The goal of this collaborative exploratory research project (0738652, Clement Yu, UIC and 0738727 Weiyi Meng, SUNY Binghamton) is to investigate the potential benefit of a dictionary-based approach for document retrieval. This project aims to demonstrate within one year that within a given domain, the use of multiple dictionaries (both domain specific dictionaries and general dictionaries) will obtain high retrieval effectiveness. The demonstration will be facilitated using existing TREC query and document collections. Rules for adding semantically related terms to queries that can yield high retrieval effectiveness within the selected domain will be identified. These rules will be carefully analyzed to obtain fundamental insights for the gain of effectiveness achieved due to the use of the dictionaries. This project is also to seek evidence that certain dictionary constructs (e.g., the frequency of use of a word in a context) can lead to significant gains in effectiveness if they are added to a dictionary. The research results from this project will lay the foundation in achieving longer-term goals that include the identification of domain independent principles of using different types of dictionaries in the same system, and the development of tools to add useful dictionary constructs across dictionaries and to assist users in query expansion semi-automatically when there are multiple dictionaries. It is expected that the proposed project can have a significant impact on search engine technology, including retrieval in specialized domains such as law and medicine, question-answering, blog retrieval and analysis, and enterprise search. Research results will be incorporated into several courses the PIs teach and students will be recruited to participate in the research activities. Research results will be disseminated through published papers as well as a textbook on Web-based search technology.

该协作探索性研究项目的目标（0738652，Clement Yu，UIC和0738727 Weiyi Meng，Suny Binghamton）是为了调查基于字典的文档检索方法的潜在好处。该项目的目的是在一年内证明，在给定的领域内，使用多个词典（域特定词典和一般词典）将获得很高的检索有效性。演示将使用现有的TREC查询和文档收集来促进。将确定可以在选定域内产生高检索有效性的查询中添加语义相关术语的规则。将仔细分析这些规则，以获取基本见解，以获取由于使用字典而获得的有效性。该项目还寻求证据表明，如果某些词典构造（例如，在上下文中使用单词的使用频率），如果将它们添加到字典中，则可以从有效性上取得显着提高。该项目的研究结果将为实现长期目标奠定基础，包括在同一系统中使用不同类型的字典识别域的独立原则，以及开发工具以跨字典添加有用的字典结构，并在有多个字典时协助用户进行查询扩展的半度性扩展。预计拟议的项目可以对搜索引擎技术产生重大影响，包括在法律和医学等专业领域的检索，提问，博客检索和分析以及企业搜索。研究结果将被纳入PIS教学的多个课程中，并将招募学生参加研究活动。研究结果将通过已发表的论文以及有关基于Web的搜索技术的教科书进行传播。项目网站（http://www.cs.binghamton.edu/~meng/docretsger.html）提供了对研究结果的访问。
