Seven Pillars of the Open Semantic Enterprise

Seven Pillars of the Open Semantic Enterprise
Guideposts for How to Make the Transition

The beginning of a new year and a new decade is a perfect opportunity to take stock of how the world is changing and how we can change with it. Over the past year I have been writing on many foundational topics relevant to the use of semantic technologies in enterprises.

In this post I bring those threads together to present a unified view of these foundations — some seven pillars — to the open semantic enterprise.

By open semantic enterprise we mean an organization that uses the languages and standards of the semantic Web, including RDF, RDFS, OWL, SPARQL and others to integrate existing information assets, using the best practices of linked data and the open world assumption, and targeting knowledge management applications. It does so using some or all of the seven foundational pieces (“pillars”) noted herein.

The foundational approaches to the open semantic enterprise do not necessarily mean open data nor open source (though they are suitable for these purposes with many open source tools available [3]). The techniques can equivalently be applied to internal, closed, proprietary data and structures. The techniques can themselves be used as a basis for bringing external information into the enterprise. ‘Open’ is in reference to the critical use of the open world assumption.

These practices do not require replacing current systems and assets; they can be applied equally to public or proprietary information; and they can be tested and deployed incrementally at low risk and cost. The very foundations of the practice encourage a learn-as-you-go approach and active and agile adaptation. While embracing the open semantic enterprise can lead to quite disruptive benefits and changes, it can be accomplished as such with minimal disruption in itself. This is its most compelling aspect.

Like any change in practice or learning, embracing the open semantic enterprise is fundamentally a people process. This is the pivotal piece to the puzzle, but also the one that does not lend itself to ready formula about pillars or best practices. Leadership and vision is necessary to begin the process. People are the fuel for impelling it. So, we’ll take this fuel as a given below, and concentrate instead on the mechanics and techniques by which this vision can be achieved. In this sense, then, there are really eight pillars to the open semantic enterprise, with people residing at the apex.

This article is synthetic, with links to (largely) my preparatory blog postings and topics that preceded it. Assuming you are interested in becoming one of those leaders who wants to bring the benefits of an open semantic enterprise to your organization, I encourage you to follow the reference links for more background and detail.

Benefits A Review of the Benefits

OK, so what’s the big deal about an open semantic enterprise and why should my organization care?

We should first be clear that the natural scope of the open semantic enterprise is in knowledge management and representation [1]. Suitable applications include data federation, data warehousing, search, enterprise information integration, business intelligence, competitive intelligence, knowledge representation, and so forth [2]. In the knowledge domain, the benefits for embracing the open semantic enterprise can be summarized as greater insight with lower risk, lower cost, faster deployment, and more agile responsiveness.

The intersection of knowledge domain, semantic technologies and the approaches herein means it is possible to start small in testing the transition to a semantic enterprise. These efforts can be done incrementally and with a focus on early, high-value applications and domains.

There is absolutely no need to abandon past practices. There is much that can be done to leverage existing assets. Indeed, those prior investments are often the requisite starting basis to inform semantic initiatives.

Embracing the pillars of the open semantic enterprise brings these knowledge management benefits:

  • Domains can be analyzed and inspected incrementally
  • Schema can be incomplete and developed and refined incrementally
  • The data and the structures within these frameworks can be used and expressed in a piecemeal or incomplete manner
  • Data with partial characterizations can be combined with other data having complete characterizations
  • Systems built with these frameworks are flexible and robust; as new information or structure is gained, it can be incorporated without negating the information already resident, and
  • Both open and closed world subsystems can be bridged.

Moreover, by building on successful Web architectures, we can also put in place loosely coupled, distributed systems that can grow and interoperate in a decentralized manner. These also happen to be perfect architectures for flexible collaboration systems and networks.

These benefits arise both from individual pillars in the open semantic enterprise foundation, as well as in the interactions between them. Let’s now re-introduce these seven pillars.

Pillar #1Pillar #1: The RDF Data Model

As I stated on the occasion of the 10th birthday of the Resource Description Framework data model, I belief RDF is the single most important foundation to the open semantic enterprise [4]. RDF can be applied equally to all structured, semi-structured and unstructured content. By defining new types and predicates, it is possible to create more expressive vocabularies within RDF. This expressiveness enables RDF to define controlled vocabularies with exact semantics. These features make RDF a powerful data model and language for data federation and interoperability across disparate datasets.

Via various processors or extractors, RDF can capture and convey the metadata or information in unstructured (say, text), semi-structured (say, HTML documents) or structured sources (say, standard databases). This makes RDF almost a “universal solvent” for representing data structure.

Because of this universality, there are now more than 150 off-the-shelf ‘RDFizers’ for converting various non-RDF notations (data formats and serializations) to RDF [5]. Because of its diversity of serializations and simple data model, it is also easy to create new converters. Once in a common RDF representation, it is easy to incorporate new datasets or new attributes. It is also easy to aggregate disparate data sources as if they came from a single source. This enables meaningful compositions of data from different applications regardless of format or serialization.

What this practically means is that the integration layer can be based on RDF, but that all source data and schema can still reside in their native forms [6]. If it is easier or more convenient to author, transfer or represent data in non-RDF forms, great [7]. RDF is only necessary at the point of federation, and not all knowledge workers need be versed in the framework.

Pillar #2 Pillar #2: Linked Data Techniques

Linked data is a set of best practices for publishing and deploying instance and class data using the RDF data model. Two of the best practices are to name the data objects using uniform resource identifiers (URIs), and to expose the data for access via the HTTP protocol. Both of these practices enable the Web to become a distributed database, which also means that Web architectures can also be readily employed (see Pillar #5 below).

Linked data is applicable to public or enterprise data, open or proprietary. It is really straightforward to employ. Structured Dynamics has published a useful FAQ on linked data.

Additional linked data best practices relate to how to characterize and classify data, especially in the use of predicates with the proper semantics for establishing the degree of relatedness for linked data items from disparate sources.

Linked data has been a frequent topic of this blog, including how adding linkages creates value for existing data, with a four-part series about a year ago on linked data best practices [8]. As advocated by Structured Dynamics, our linked data best practices are geared to data interconnections, interrelationships and context that is equally useful to both humans and machine agents.

Pillar #3 Pillar #3: Adaptive Ontologies

Ontologies are the guiding structures for how information is interrelated and made coherent using RDF and its related schema and ontology vocabularies, RDFS and OWL [10]. Thousands of off-the-shelf ontologies exist — a minority of which are suitable for re-use — and new ones appropriate to any domain or scope at hand can be readily constructed.

In standard form, semantic Web ontologies may range from the small and simple to the large and complex, and may perform the roles of defining relationships among concepts, integrating instance data, orienting to other knowledge and domains, or mapping to other schema [11]. These are explicit uses in the way that we construct ontologies; we also believe it is important to keep concept definitions and relationships expressed separately from instance data and their attributes [9].

But, in addition to these standard roles, we also look to ontologies to stand on their own as guiding structures for ontology-driven applications (see next pillar). With a relatively few minor and new best practices, ontologies can take on the double role of informing user interfaces in addition to standard information integration.

In this vein we term our structures adaptive ontologies [11,12,13]. Some of the user interface considerations that can be driven by adaptive ontologies include: attribute labels and tooltips; navigation and browsing structures and trees; menu structures; auto-completion of entered data; contextual dropdown list choices; spell checkers; online help systems; etc. Put another way, what makes an ontology adaptive is to supplement the standard machine-readable purpose of ontologies to add human-readable labels, synonyms, definitions and the like.

A neat trick occurs with this slight expansion of roles. The knowledge management effort can now shift to the actual description, nature and relationships of the information environment. In other words, ontologies themselves become the focus of effort and development. The KM problem no longer needs to be abstracted to the IT department or third-party software. The actual concepts, terminology and relations that comprise coherent ontologies now become the explicit focus of KM activities.

Any existing structure (or multiples thereof) can become a starting basis for these ontologies and their vocabularies, from spreadsheets to naïve data structures and lists and taxonomies. So, while producing an operating ontology that meets the best practice thresholds noted herein has certain requirements, kicking off or contributing to this process poses few technical or technology demands.

The skills needed to create these adaptive ontologies are logic, coherent thinking and domain knowledge. That is, any subject matter expert or knowledge worker likely has the necessary skills to contribute to useful ontology development and refinement. With adaptive ontologies powering ontology-driven apps (see next), we thus see a shift in roles and responsibilities away from IT to the knowledge workers themselves. This shift acts to democratize the knowledge management function and flatten the organization.

Pillar #4 Pillar #4: Ontology-driven Applications

The complement to adaptive ontologies are ontology-driven applications. By definition, ontology-driven apps are modular, generic software applications designed to operate in accordance with the specifications contained in an adaptive ontology. The relationships and structure of the information driving these applications are based on the standard functions and roles of ontologies, as supplemented by the human and user interface roles noted above [11,12,13].

Ontology-driven apps fulfill specific generic tasks. Examples of current ontology-driven apps include imports and exports in various formats, dataset creation and management, data record creation and management, reporting, browsing, searching, data visualization, user access rights and permissions, and similar. These applications provide their specific functionality in response to the specifications in the ontologies fed to them.

The applications are designed more similarly to widgets or API-based frameworks than to the dedicated software of the past, though the dedicated functionality (e.g., graphing, reporting, etc.) is obviously quite similar. The major change in these ontology-driven apps is to accommodate a relatively common abstraction layer that responds to the structure and conventions of the guiding ontologies. The major advantage is that single generic applications can supply shared functionality based on any properly constructed adaptive ontology.

This design thus limits software brittleness and maximizes software re-use. Moreover, as noted above, it shifts the locus of effort from software development and maintenance to the creation and modification of knowledge structures. The KM emphasis can shift from programming and software to logic and terminology [12].

Pillar #5 Pillar #5: A Web-oriented Architecture

A Web-oriented architecture (WOA) is a subset of the service-oriented architectural (SOA) style, wherein discrete functions are packaged into modular and shareable elements (”services”) that are made available in a distributed and loosely coupled manner. WOA uses the representational state transfer (REST) style. REST provides principles for how resources are defined and used and addressed with simple interfaces without additional messaging layers such as SOAP or RPC. The principles are couched within the framework of a generalized architectural style and are not limited to the Web, though they are a foundation to it [14].

REST and WOA stand in contrast to earlier Web service styles that are often known by the WS-* acronym (such as WSDL, etc.). WOA has proven itself to be highly scalable and robust for decentralized users since all messages and interactions are self-contained.

Enterprises have much to learn from the Web’s success. WOA has a simple design with REST and idempotent operations, simple messaging, distributed and modular services, and simple interfaces. It has a natural synergy with linked data via the use of URI identifiers and the HTTP transport protocol. As we see with the explosion of searchable dynamic databases exposed via the Web, so too can we envision the same architecture and design providing a distributed framework for data federation. Our daily experience with browser access of the Web shows how incredibly diverse and distributed systems can meaningfully interoperate [15].

This same architecture has worked beautifully in linking documents; it is now pointing the way to linking data; and we are seeing but the first phases of linking people and groups together via meaningful collaboration. While generally based on only the most rudimentary basis of connections, today’s social networking platforms are changing the nature of contacts and interaction.

The foundations herein provide a basis for marrying data and documents in a design geared from the ground up for collaboration. These capabilities are proven and deployable today. The only unclear aspects will be the scale and nature of the benefits [16].

Pillar #6 Pillar #6: An Incremental, Layered Approach

To this point, you’ll note that we have been speaking in what are essentially “layers”. We began with existing assets, both internal and external, in many diverse formats. These are then converted or transformed into RDF-capable forms. These various sources are then exposed via a WOA Web services layer for distributed and loosely-coupled access. Then, we integrate and federate this information via adaptive ontologies, which then can be searched, inspected and managed via ontology-driven apps. We have presented this layered architecture before [13], and have also expressed this design in relation to current Structured Dynamics’ products [17].

A slight update of this layered view is presented below, made even more general for the purposes of this foundational discussion:

Open Enterprise Architecture
(click to expand)

Semantic technology does not change or alter the fact that most activities of the enterprise are transactional, communicative or documentary in nature. Structured, relational data systems for transactions or records are proven, performant and understood. On its very face, it should be clear that the meaning of these activities — their semantics, if you will — is by nature an augmentation or added layer to how to conduct the activities themselves.

This simple truth affirms that semantic technologies are not a starting basis, then, for these activities, but a way of expressing and interoperating their outcomes. Sure, some semantic understanding and common vocabularies at the front end can help bring consistency and a common language to an enterprise’s activities. This is good practice, and the more that can be done within reason while not stifling innovation, all the better. But we all know that the budget department and function has its own way of doing things separate from sales or R&D. And that is perfectly OK and natural.

Clearly, then, an obvious benefit to the semantic enterprise is to federate across existing data silos. This should be an objective of the first semantic “layer”, and to do so in a way that leverages existing information already in hand. This approach is inherently incremental; if done right, it is also low cost and low risk.

Pillar #7 Pillar #7: The Open World Mindset

As these pillars took shape in our thinking and arguments over the past year, an illusive piece seemed always to be missing. It was like having one of those meaningful dreams, and then waking up in the morning wracking your memory trying to recall that essential, missing insight.

As I most recently wrote [1], that missing piece for this story is the open world assumption (OWA). I argue that this somewhat obscure concept holds within it the key as to why there have been decades of too-frequent failures in the enterprise in business intelligence, data warehousing, data integration and federation, and knowledge management.

Enterprises have been captive to the mindset of traditional relational data management and its (most often unstated) closed world assumption (CWA). Given the success of relational systems for transaction and operational systems — applications for which they are still clearly superior — it is understandable and not surprising that this same mindset has seemed logical for knowledge management problems as well.  But knowledge and KM are by their nature incomplete, changing and uncertain. A closed-world mindset carries with it certainty and logic implications not supportable by real circumstances.

This is not an esoteric point, but a fundamental one. How one thinks about the world and evaluates it is pivotal to what can be learned and how and with what information. Transactions require completeness and performance; insight requires drawing connections in the face of incompleteness or unknowns.

The absolute applicability of the semantic Web stack to an open-world circumstance is the elephant in the room [1]. By itself, the open world mindset provides no assurance of gaining insight or wisdom. But, absent it, we place thresholds on information and understanding that may neither be affordable nor achievable with traditional, closed-world approaches.

And, by either serendipity or some cosmic beauty, the open world mindset also enables incremental development, testing and refinement. Even if my basic argument of the open world advantage for knowledge management purposes is wrong, we can test that premise at low cost and risk. So, within available budget, pick a doable proof-of-concept, and decide for yourself.

Seven Pillars The Foundations for the Open Semantic Enterprise

The seven pillars above are not magic bullets and each is likely not absolutely essential. But, based on today’s understandings and with still-emerging use cases being developed, we can see our open semantic enterprise as resulting from the interplay of these seven factors:

Open Semantic Enterprise

Thirty years of disappointing knowledge management projects and much wasted money and effort compel that better ways must be found. On the other hand, until recently, too much of the semantic Web discussion has been either revolutionary (“change everything!!”) or argued from pie-in-the-sky bases. Something needs to give.

Our work over the past few years — but especially as focused in the last 12 months — tells us that meaningful semantic Web initiatives can be mounted in the enterprise with potentially huge benefits, all at manageable risks and costs. These seven pillars point to way to how this might happen. What is now required is that eighth pillar — you.

[1] See, M.K. Bergman, 2009. “The Open World Assumption: Elephant in the Room“, AI3:::Adaptive Information blog, December 21, 2009.
[2] In most instances, semantic technologies are poorly suited to transactional or operational applications. Also, there are instances in modeling specific closed-world domains where ontologies can be quite useful, such as in aerospace, petrochemicals, engineering, etc., where the scope of the domain can be precisely bounded and defined. Such efforts tend to be high cost with lengthy lead times. There are vendors who support efforts in these areas, though my company, Structured Dynamics, does not. Our focus and the more generally suitable case for semantic technologies we believe is in knowledge representation and management.

[7] For example, for dataset authoring, Structured Dynamics has developed irON, an instance record and object notation that can be serialized as JSON (called irJSON), XML (called irXML) or comma-separated values (or CSV comma-delimited files, called commON). The purpose of these notations is to provide easier authoring environments and scripting support to RDF-ready datasets. The advantage is to shield users from the nuances of RDF. The design of commON is especially geared to using spreadsheets as authoring environments for instance record tables or simple outline structures.  See further the irON specification.

[9] Our best practices approach makes explicit splits between the “ABox” (for instance data) and “TBox” (for ontology schema) in accordance with our working definition for description logics, a fundamental underpinning for how we use RDF:

“Description logics and their semantics traditionally split concepts and their relationships from the different treatment of instances and their attributes and roles, expressed as fact assertions. The concept split is known as the TBox (for terminological knowledge, the basis for T in TBox) and represents the schema or taxonomy of the domain at hand. The TBox is the structural and intensional component of conceptual relationships. The second split of instances is known as the ABox (for assertions, the basis for A in ABox) and describes the attributes of instances (and individuals), the roles between instances, and other assertions about instances regarding their class membership with the TBox concepts.”

By open semantic enterprise we mean an organization that uses the languages and standards of the semantic Web, including RDF, RDFS, OWL, SPARQL and others to integrate existing information assets, using the best practices of linked data and the open world assumption, and targeting knowledge management applications.

17 thoughts on “Seven Pillars of the Open Semantic Enterprise

  1. I agree with most of what you have written; however I think that rdf is not a natural way for humans to view data/content. I also think that because of the general lack of uptake and knowledge of semantic technologies and standards a closer look and questioning of the validity of the suggested solutions needs to be undertaken. In my view many of the concepts concerning efforts to bring about a semantic web are heavily skewed to needs of computation and not to the needs of the humans that will be undertaking KM task. Maybe there needs to be a synthesis of media and communications studies with semantic technology to bring about some new views and ideas in this area.

  2. With regard to the open-world assumption, I would suggest that the strict logical interpretation (as in description logic) of ontological content is a complementary issue. Cyc and Vulcan (SILK) take this problem head on. In OWL, most people would say birds fly. Then they consider penguins. The lack of defeasibility, both in thinking about knowledge and in the technology of the semantic web at this point may prove as significant as confusion (or lack of awarness) of open versus closed world perspectives.

    In this post you begin with the benefits of integration using open semantic technologies, which is great, but how many enterprises want to be open or semantic versus receiving benefits from openness and semantics? So, perhaps the term “open semantic enterprise” is a misnomer. Or, perhaps, it would apply to an interesting but relatively small segment of the potential market for the open semantics for which you advocate so well.

  3. @Paul,

    As I tried to make clear, OWA is not complementary, but fundamental. I will research the ‘defeasibility’ lack.

    As for the ‘openness’ observations, I likely was not clear in this portion:

    “The foundational approaches to the open semantic enterprise do not necessarily mean open data nor open source (though they are suitable for these purposes with many open source tools available [3]). The techniques can equivalently be applied to internal, closed, proprietary data and structures. The techniques can themselves be used as a basis for bringing external information into the enterprise. ‘Open’ is in reference to the critical use of the open world assumption.”

    It is true that “open” conveys many things to many people. (We had our own internal dialog about the wisdom of the ‘open’ moniker.)

    Truthfully, I would prefer a different handle than the “open world assumption” because of these conflations.

    If you have an alternative description, I would seriously consider it.

    Thanks, Mike

  4. @Bruce,

    As stated, I stand by my assertion about the RDF data model. Please read more closely: I am not advocating RDF in all aspects; simply at the data federation layer.

    Whatever data format and serialization is comfortable to you for whatever step in the process, go for it! Though RDF can be used for data transfer our own view is that is largely immaterial; its real use is in internal data federation.

    With our irON work and support for RDFizers, I hope we are clearly signaling our support for whatever data format you want in the wild.

    Via this perspective, there really should be no trade-off between “human” and “machine” uses for data. Use the format that best suites the task at hand. In the end, we can boil it all down to the interoperable canonical model.

    Thanks, Mike

  5. The seven pillars presented are a mere summary of the European Semantic Technology research programme of the last 10 years. The problem here (and true for many business-it problems) is that these pillars are technology-religious from the beginning. Ontologies should not be build by techies, but by the experts themselves. Just like in BPM where those that decide on which process is going to fulfill which business objective, in Business Semantics Management (check my blog business experts decide on the meaning of terms and rules based on their business goals.

    This brings me to another important pillar that is missing here, or should I say first class citizen: the human stakeholders in the extended enterprise themselves. Business experts in the business zone of the “semantic enterprise” must be facilitated with the right methods and tools (see e.g., to agree on the meaning of their vocabularies and business rules (i.e. business semantics) before even thinking about flattening a version of that agreement into an enterprise information model (whether in monolithic OWL or widely known UML) that can be passed on to application builders in the tech zone of the enterprise. If the techies finds flaws in enterprise information model (E.g., some terms are underspecified leading to misunderstandings or so) these new requirements for starting a new consensus process is fed back to the business zone. SBVR is a promising standard based on the proven foudnations of fact-oriented modelling to allow business experts define business vocabulary and rule semantics in a natural manner.

    I also like the emphasis of the open world assumption. I have been evangelising this for years as well. I call the opposite: the closed world “syndrome”.

  6. From a purely theoretical perspective I think the concept of semantics is exciting. However the approaches suggested are flawed. For example ontologies are derived from the sturdy of plants and animals. One of the primary reasons ontologies are applicable in this domain is that the objects defined in these ontologies are constrained or bounded by physical, chemical or biological theories. Scientific information such as cancer research data also has some of these constraints. As a result the subject matter experts and their constituents in their community of interest all agree to conform to a well-defined set of natural theories that help govern the ontologies, taxonomies and semantics for the objects used in the community.

    Business information has no “natural” constraints. This becomes evident when trying to reverse engineer a taxonomy or ontology within an existing enterprise. There are no natural boundaries, definitions or theories governing the meaning of terms. They are some generally accepted terms in the accounting arenas such as defined in GAPP but even those are subject to creative interpretation or manipulation. Another factor that diminishes the value of ontologies in a business environment is the need to have “adaptive” ontologies. This indicates there is already a concern than the ontology is not stable and must be adapted. What is the volatility of the ontology? How frequently will it need to be adapted and under what circumstances and by what process? What this seems to imply is that the ontologies are subjective, volatile and unstable.

    Extracting the semantics from data when replacing legacy systems or attempting to integrate systems such as customer data integration has a purpose but that purpose and value is only limited to the duration of the project. Once the project is completed those artifacts, like requirements are historical and typically never referred to again. I suggest that building ontologies, taxonomies and pursing semantics have a limited half-life.

    The lack of natural constraints and stability and the limited business value and half-life of semantics suggests that it although an interesting theoretical pursuit, will contribute little measurable value to the business. Even within the world of nature there is increasing anxiety with the ontology that defines the animals species given that with improved science some of the characteristics that defined a species are no longer considered unique and as a result the structure of the ontology no longer represents an accurate model. Imagine this volatility when attempting to define abstract, unstructured, ill-conceived and ambiguous business terms. The result may be interesting but of minimal value to improving the business.

    Another factor to consider is that business training does not include skills in building ontologies, taxonomies or the understanding of semantics. This expertise is certainly no evident in IT nor is a hiring criteria for CIO’s. So where will the expertise to develop these elaborate ontologies come from and who will continually adapt them within businesses? Will there be a department of ontologies, taxonomies and semantics?

    Ultimately unless we can show a strong correlation between the development and maintenance of ontologies, taxonomies and the use of semantics to the business, this will continue to be a theoretical pursuit. It is a pursuit that I thoroughly enjoy but unlikely one on which to build a career.
