May I suggest you to have a look at our semantic tagger at http://www.wikimeta.org. Methods and algorithms are described in some papers but this one is the more accurate with the actual version of our system:

Canadian AI 2011 – May 2011 – Automatic Semantic Web annotation of named entities
(referenced here http://dl.acm.org/citation.cfm?id=2018202 and downloadable here http://www.echarton.com/download/pdf/2011/sem-labeler-canai.pdf)

Vary nice site and survey.

Thanks for the updates; I will make them in the next day or three. I will also change the categories, as requested.

Please note SPARQLmotion has been listed since 2008. Go to http://www.mkbergman.com/sweet-tools/ and do a search.

Thanks, Mike

TopBraid Live is an enterprise SOA-capable Semantic Web application platform optimized for delivering dynamic model-based applications. With TopBraid Live, you can quickly implement solutions that integrate data, content, application services and user interactions. More information is available at: http://www.topquadrant.com/products/TB_Live.html

We believe TopBraid Live fits in the category “Composite App/Framework” while TopBraid Composer is probably a better fit for “Ontology/Vocabulary Editor” or IDE category.

Another entry for the “Ontology/Vocabulary Editor” is TopBraid Enterprise Vocabulary Net (EVN). Where TopBraid Composer is a very powerful Eclipse plugin for expert users, TopBraid EVN is a web-based system that targets a different user base.

TopBraid Enterprise Vocabulary Net (TopBraid EVN) is a web-based solution for simplified development and management of interconnected controlled vocabularies. It supports business stakeholders who need to collaborate on defining and linking enterprise vocabularies, taxonomies, thesauri and ontologies used for information integration, customization and search. More information is available at: http://www.topquadrant.com/solutions/ent_vocab_net.html

TopBraid Ensemble (TBE) is the quickest route from an ontology to a working web application. Once you have your ontology, optionally with some RDF data, all that remains to be done is pointing a web browser to one of the pre-configured application templates. Applications pre-packaged with Ensemble let you navigate through semantic models and corresponding data, using trees, grids and search form components. They can also include maps and graph visualization and query builder components.

TopBraid Ensemble (applications are not for browsing only. They feature model-driven edit forms, drag and drop and auto-complete operations. All TBE applications offer full multi-user support. Ensemble applications work with any data store supported by the TopBraid Suite and with all popular web browsers. Pre-packaged applications are merely a starting point with Ensemble. Using only a web browser, you can easily customize applications by adding, removing and reconfiguring components, popup dialog boxes, and additional pages to create multi-page applications. More information at: http://www.topquadrant.com/products/TB_Ensemble.html

Ensemble may fit in the category you are calling “Browser (RDF, OWL or semantic)” or since TBE applications fully support multi-user editing and collaboration, a better fit may be “Wikis and -related” category or even “Data Presentation”.

SPARQLMotion is visual a scripting language and an engine for semantic data processing. Scripts implementing sophisticated data services and processing such queries and data transformations can be quickly assembled with easy to use graphical tools saving weeks of development time. More information is available at: http://www.topquadrant.com/products/SPARQLMotion.html

SPARQLMotion fits in your “Mashup/Meshup Framework” category

TopSPIN is an inference engine that works with SPARQL Rules (aka SPIN). SPARQL Rules are constraints and inference rules on Semantic Web models implemented using SPARQL. Constraints use SPARQL ASK, rules use SPARQL CONSTRUCT and SPARQL Update (DELETE, INSERT). Also supported are meta-modeling capabilities that allow users to define their own SPARQL functions and query templates without having to write Java code. TopSPIN inferences directly over RDF data without a need to transform RDF into some other format as it is commonly done with other inference engines. It provides incremental inferencing and explanations. More information is available at: http://www.topquadrant.com/products/SPIN.html. There is an open source SPIN API at http://topbraid.org/spin/api/

Knoodl’s capabilities include:

Cloud-based application (Amazon EC2)
Ontology editing
Ontology import/export
Collaboration and queryable threaded discussions
Role-based security
Choice of scalable RDF stores (Jena, Mulgara, or Oracle)
Ontology Guided Search
SPARQL Endpoints
HTTP service for graph updates
SPARQL query wizard
User designed views of query results
