The goal of this collaborative exploratory research project (0842546, Clement Yu, UIC and 0842608 Weiyi Meng, SUNY Binghamton) is to investigate two important problems in opinion retrieval. The first is to determine whether a negation word flips the sentiment of an opinionated word and the second is to examine how the opinions about a topic change over time and what causes significant changes. This project aims to demonstrate within 18 months that within two domains (consumer products/services and medical/health), whether a negation word flips the polarity of an opinionated word or phrase can be accurately determined when there is a single occurrence of such negation word in a sentence, and the significant time points and words/phrases that characterize the changes of sentiments for a given topic can be accurately obtained. The research results from this project will lay the foundation in achieving longer-term goals that include determining the polarity of the sentiment of a feature with reference to a given query in any given domain, identifying the events that cause the significant change of sentiments, measuring the intensity of sentiments and its change over time, and studying the interactions between the negation and temporal aspects of opinion retrieval. It is expected that the proposed project can have a significant impact on future search engine technology, information retrieval, text mining, and blog retrieval and analysis. 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. The project Web site (http://www.cs.binghamton.edu/~meng/OpRetSGER.html) provides access to research results.

这个合作探索性研究项目（0842546，UIC 的 Clement Yu 和 0842608 Weiyi Jia，SUNY Binghamton）的目标是研究观点检索中的两个重要问题。第一个是确定否定词是否会改变固执己见的词的情绪，第二个是检查关于某个主题的观点如何随着时间的推移而变化以及导致重大变化的原因。该项目旨在在18个月内证明，在两个领域（消费品/服务和医疗/健康）内，当句子中出现一次否定词时，可以准确判断否定词是否会翻转固执己见的词或短语的极性，并准确获取表征给定主题情绪变化的重要时间点和词/短语。该项目的研究成果将为实现长期目标奠定基础，包括根据任何给定领域中的给定查询确定特征的情感极性，识别导致情感显着变化的事件，测量情感强度及其随时间的变化，以及研究意见检索的否定和时间方面之间的相互作用。预计该项目将对未来的搜索引擎技术、信息检索、文本挖掘以及博客检索和分析产生重大影响。研究成果将被纳入 PI 教授的几门课程中，并招募学生参与研究活动。研究成果将通过发表的论文进行传播。该项目网站 (http://www.cs.binghamton.edu/~meng/OpRetSGE​​R.html) 提供对研究成果的访问。
