論文の詳細を見る
This paper presents a method of finding a specification page on the Web for a given object (e.g., ``Ch. dYquem) and its class label (e.g., ``wine). A specification page for an object is a Web page which gives concise attribute-value information about the object (e.g., ``county-``Sauternes) in well formatted structures. A simple unsupervised method using layout and symbolic decoration cues was applied to a large number of the Web pages to acquire candidate attributes for each class (e.g., ``county for a class ``wine). We then filter out irrelevant words from the putative attributes through an author-aware scoring function that we called site frequency. We used the acquired attributes to select a representative specification page for a given object from the Web pages retrieved by a normal search engine. Experimental results revealed that our system greatly outperformed the normal search engine in terms of this specification retrieval.
