Context-aware web retrieval

点击翻译按钮获取中文摘要

A "genre" is a classifying statement that allows us to recognize items that are similar, even in the face of great diversity. There are many different web page genres, from journal articles to personal home pages to FAQs. Genres cut across all knowledge domains. For instance, a journal article is a journal article whether in engineering or sociology, and an FAQ is an FAQ whether about how to plant a tree or how to hook up a new device to your computer. Similarly, a type of task is not domain specific; for example, shopping is a transactional task and should retrieve web pages of appropriate genres (shopping sites), whether shopping for medicine or handbags, i.e., there is a relationship between type of task and the genre(s) of web pages that should satisfy that task.
