Consistency check of words on link among hypertext documents

Consistency check algorithm is shown below.

1. For each target HTML document, extract anchor text, (eg, a text enclosed  by a pair of <a> and </a> in a HTML document), referencing URL (eg, a url  described in the 'href' attribute within anchor tag), and document texts  referenced, and then construct a tuple with them.

2. For each anchor text in a tuple, expand it to several words that include  synonyms or translated words of anchor text by using an existing word or  translation database. In Fig 2, original anchor text is expanded into three  words including text itself, synonym and translated word.

3. For each expanded word, search the word in referenced document. If none  of expanded words are found, the anchor text is not used in referenced  document. This means that two documents (document that holds anchor text
