CAREER: Contextual Link Analysis

本项目提案侧重于主题链接分析问题，目的是提高网络搜索结果的相关性。一个网页(或作者)并不是在所有主题上都具有同等的权威性。然而，传统的链接分析技术只考虑权威性的单一度量，很少或根本不考虑派生该权威性的主题或社区。这项研究找到了确定公认权威的背景的方法，并将该背景作为话题性或社区认可纳入更准确的声誉自动分析。该项目通过区分受欢迎程度、质量和权威，进一步改进了链接分析。通过将这种分析集成到基本的链接分析技术中，使用人的相关性和质量判断来证明搜索结果质量的改进。这一背景链接分析提供了新的机会，以显著改进对权威性的衡量，从而改善搜索引擎结果排名(以及用于其他目的的主题排名)，并更好地理解相互关联的文献网络，如网络和学术出版物的主题结构。该项目还包括教育和推广活动，包括一项计划，旨在激发本科生对地区学校计算机科学研究的兴趣和经验，同时促进附近教职员工之间的互动。项目网页(http://www.cse.lehigh.edu/~brian/nsf/career-05.html)提供了研究结果和有关项目的其他信息。

This project proposal focuses on the problem of topical link analysis with a goal to improve the relevance of web search results. A web page (or author) is not equally authoritative on all topics. However, traditional link analysis techniques consider only a single measure of authority, with little or no concern for the topic or community from which that authority is derived. This research finds ways to determine the context of recognized authority, and to incorporate that context as topicality or community recognition into more accurate automated analyses of reputation. This project further improves link analysis by distinguishing between popularity, quality, and authority. By integrating such analysis into fundamental link analysis techniques, search result quality improvements are demonstrated using human relevance and quality judgments. This contextual link analysis provides new opportunities to significantly improve measurements of authority and thus search engine result rankings (as well as topical rankings for other purposes), and to better understand the topical structure of interlinked document networks such as the Web and scholarly publications. The project additionally incorporates educational and outreach activities, including a program to stimulate undergraduate interest and experience in computer science research in area schools, while promoting interaction among nearby faculty.
