中文摘要： 主要研究基于网络的情感语义词 汇抽取和语义情感词典自动构建的关键技术。利用互联网络海量信息和技术，通过给定的语义情感概念种子和已有情感词典，基于网络信息中情感概念共起互信息频率特征、概念共现网络结构特征以及聚类的算法抽取情感概念，计算情感概念的情感权值和概念间的语义关系权值。讨论多维情感语义词典的构建结构，包括情感概念的多级分类和多种语义关系构建。构建和利用语义关系的推导规则，自动推导新的情感语义关系，并对构建的情感语义词典进行评价和算法修整。同时基于构建的中文情感语义词典和藏汉词汇词典，研究构建藏文情感语义词典。最后通过基于构建获得的汉藏情感语义词典对网络舆情进行细粒度情感计算和情感倾向分析技术研究，进一步验证情感语义词典构建方法和词典的有效性。

英文摘要： Research the key technology about Web extraction of semantic emotional concepts and automated construction of semantic lexicon. Using Internet's huge amounts of information and technology, through some given semantic emotional concept of seeds and built lexicons, based on co-occurrence characteristics of retrieval concepts' hits and co-occurrence network structure characteristics of the seeds and extracted concepts and clustering algorithm, to extract the emotional concept in bootstrapping, and to calculate the feelings weights of emotional concepts and the semantic relations' weights between concepts. Discuss the multidimensional structure of emotional semantic dictionary, including multi-stage classification of emotional concept and the building of semantic relations. Building and using derivation semantic rules of emotional relation, to automatic derivation new emotional semantic relations, and to evaluate the semantic lexicon construction and recondition the algorithm for extracting semantic emotional lexicon based the Web. At the same time, to research construction method of Tibetan semantic emotional lexicon based on the constructed Chinese lexicon and Sino-Tibetan lexicon. Finally, based on constructed semantic emotional lexicon in Sino-Tibetan, to study affective computing and analysis of network public opinion, and verify the e effectiveness of semantic emotional lexicon and its building methods based on Web in further.
