On-Line Applications

Please access http://lcl.uniroma1.it to play with our web applications:

SSI – a state of art knowledge-based Word Sense Disambiguation algorithm.

TermExtractor: a web application that 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.

TAV – a tool to browse and validate an automatically learned taxonomy or ontology.

Valido – a tool to help human annotators in the task of semantically tagging texts. It is based on the SSI algorithm.

OntoLearn – a tool and a set of algorithms to acquire a lexical ontology fully from scratch
