Corpus and Web: Two Allies in Building and Automatically Expanding Conceptual Classes
Nicolas Béchet, Jacques Chauché, Violaine Prince, Mathieu Roche · 2010
In this paper, the approaches to building and expanding conceptual classes are presented. The classes are built with syntactic and semantic information provided by a corpus. Then, expansion is addressed by using the objects of syntactic relations found in the corpus. Relations between classes are thus designed. They are called induced relations. Then we use objects of induced syntactic relations (called complementary objects) to expand conceptual classes. We propose an automatic experimental protocol to measure the relevance of the provided concepts. The protocol helps alleviating the judgment effort of a human expert. The expansion method is evaluated and mixed in order to provide the most reliable technique in expanding conceptual classes.
