Resources & Tools

Within the Ontotext project we have developed the following resources and tools:

• EntityPro. A module for the automatic recognition of named entities, based on machine learning techniques (Support Vector Machines). It is available within the TextPro platform for the linguistic analysis of texts.



• Co-reference resolution module. An algorithm to decide with a certain degree of confidence wether two mentions refer to the same entity or not.



• Ita-Chronos. A rule-based system for the automatic recognition and normalization of temporal expressions.



• Italian Content Annotation Bank (I-CAB). A corpus of Italian news stories annotated manually with temporal expressions, entities (e.g. persons, organizations, etc.), and relations between entities.



• SentiWordNet. A lexical resource in which each WordNet synset is associated to three numerical scores describing respectively how objective, positive, and negative the terms contained in the synset are.



• OntoTDT An unsupervised and language independent module for the detection of the topic/s dealt with in a collection of texts.



• Domain Ontologies. Aiming at building a large knowledge base from linguistic resources and web resources, a series of domain ontologies have been built in different fields, such as sport, broadcasters, local administration, arts and professions.
