Text-2-Knowledge:una piattaforma linguistico-computazionale per l'estrazione di conoscenza da testi

The paper describes the automatic extraction of domain knowledge from Italian document collections and presents a fully-implemented ontology learning system (T2K, Text-2-Knowledge) that includes a battery of tools for Natural Language Processing, statistical text analysis and machine learning. Evaluated results show the considerable potential of systems like T2K, exploiting an incremental interleaving of NLP and machine learning techniques for accurate large-scale semi-automatic extraction and structuring of domain-specific knowledge.
