Acquiring Part-Whole Relation from the Web

The Web becomes an important resource of knowledge acquisition with the rapid development of Internet.The acquisition of part-whole relations is an important sub-task of knowledge acquisition.We proposed a method of acquiring part-whole relations from the Web using the search engine.Firstly,to acquire corpus rich in part-whole relations from the Web,we construct a type of query intended for part-whole relations.Secondly,we extract part-whole relations by filtering the corpus according to the HTML tags and the query formats.Finally,we define a measure of verifying the part-whole relations according to characteristics of part-whole relation expressions and pa-tterns of Chinese word formation.The experimental result shows that our method achieves the accuracy of 86% in the top twenty results and the best F-measure of 64%.
