This AI3 blog maintains Sweet Tools, the largest listing of about 800 semantic Web and -related tools available. Most are open source. Click here to see the current listing!
I have been assembling for some time a listing of semantic Web-related software applications and tools. My first partial listing had about 50 sources. I recently noted the W3C’s semantic Web wiki listing of about 70 sources. I then came across the EU’s AKT (Advanced Knowledge Technologies) project, which also has about 75 tools compiled. Protégé also has a fairly long list of plugins, but not unfortunately well organized. Complicating matters still was the listing of natural language processing tools listed at the Natural Language Software Registy, another fantastic resource particularly in the annotation and information extraction arena.
Semantic Web tool sets span from comprehensive engineering environments to specific converters and editors and the like. The entire workflow extends from getting the initial content, annotating or tagging it according to existing or built ontologies, reconciling heterogeneities, and then storing and managing the RDF or OWL with subsequent querying and inferencing.
There are certainly more tools extant, and I made some choices to exclude some marginal tools (Sourceforge, for example, has more than 200 semantic Web-related projects, but the vast majority appear moribund with no actual software to download).
Thus, listed below, are today’s current, most comprehensive list of 175 semantic Web software tools and applications. I am now further characterizing these offline as to open source v. proprietary and categorizing according to SW-related workflow. I may later post those expansions.
I also welcome tool suggestions. I think the ESW tools listing is the best place ongoing for such a compilation, but so far I am not liking what I am seeing in vendors using hype to characterize their tools versus more dispassionate descriptions by practitioners.

Hi everybody!
TermExtractor, my master thesis, is online at the
address http://lcl2.di.uniroma1.it.
TermExtractor is a FREE and high-performing software package for Terminology
Extraction. The software helps a web community to
extract and validate relevant domain terms in their
interest domain, by submitting an archive of
domain-related documents in any format
(txt, pdf, ps, dvi, tex, doc, rtf, ppt, xls, xml,
html/htm, chm, wpd and also zip archives.)
TermExtractor extracts terminology consensually
referred in a specific application domain. The
software takes as input a corpus of domain documents,
parses the documents, and extracts a list of
“syntactically plausible” terms (e.g. compounds,
adjective-nouns, etc.).
Documents parsing assigns a greater importance
to terms with text layouts (title, bold, italic,
underlined, etc.). Two entropy-based measures, called
Domain Relevance and Domain Consensus, are then used.
Domain Consensus is used to select only the terms
which are consensually referred throughout the corpus
documents. Domain Relevance to select only the terms
which are relevant to the domain of interest, Domain
Relevance is computed with reference to a set of
contrastive terminologies from different domains.
Finally, extracted terms are further filtered using
Lexical Cohesion, that measures the degree of
association of all the words in a terminological
string.
