TermExtractor is a software package for automatic
building, validation and maintenance of glossaries in
english language.

TermExtractor extracts terminology consensually
referred in a specific application domain. The package
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. Accept files formats are: txt, pdf, ps, dvi,
tex, doc, rtf, ppt, xls, xml, html/htm, chm, wpd and
also zip archives.
