Pattern-Based Ontology Construction from Selected Wikipedia Pages

چکیده
In this paper, we describe how ontologies can be built automatically from definitions obtained by searching Wikipedia for lexico-syntactic patterns based on the hyponymy relation. First, we describe how definitions are retrieved and processed while taking into account both recall and precision. Further, concentrating only on precision, we show how a consistent and useful domain ontology can be created with a beneficial precision of 80%.
