Abstract

We present GEO (Generating an Extensional definition from an Ostensive definition), a method to exhaustively gather items falling under an ostensively defined concept from the Web. By utilizing structural information about HTML documents, GEO automatically and efficiently gathers thousands of items from Web pages taking only 2 or 3 items as input. GEO also yields high precision (0.99 at maximum, 0.97 in average over a set of inputs). We also introduce a new style of searching information, called Item Search, in which GEO plays an essential role. Item Search can look for items in a targeted category that are the best matches against a given query. Some examples of Item Search are presented as the proof-of-concept of the idea.
