摘要
网页排序算法的好坏很大程度上影响了万维网搜索引擎的用户体验。语义网为万维网带来了机器可理解的资源描述信息,也为搜索引擎带来了更大的挑战:搜索引擎的检索和排序的对象将不再局限于网页,而是包括了任何可以由URI唯一标识的对象,比如本体、本体中的词汇等等。本文介绍了语义网中不同的排序问题和目前已有的一些算法,并展望了语义网未来面临的排序问题和可能的解决方法。
The Web page ranking algorithms determine the user experience of search engines to a great extent. While the Semantic Web brings the machine-understandable resource description to the traditional World Wide Web, it brings more challenge to the search engines： the objects to be retrieved and ranked are no longer limited to Web pages, and they extensively contain objects which can be identified by URI, such as ontologies and vocabularies defined within ontologies. The paper expatiates diverse ranking problems in semantic Web and some algorithms to solve them, and finally gives a prospect for the future ranking problems and possible solutions.
