  3. A concept - based approach is expected to resolve the word sense ambiguities in information retrieval and apply the semantic importance of the concepts, instead of the term frequency, to representing the contents of a document. consequently, a formalized document framework is proposed. the document framework is used to express the meaning of a document with the concepts which are expressed by high semantic importance. the framework consists of two parts : the " domain " information and the " situation background " information of a document. a document - extracting algorithm and a two - stage smoothing method are also proposed. the quantification of the similarity between the query and the document framework depends on the smoothing method. the experiments on the trec6 collection demonstrate the feasibility and effectiveness of the proposed approach in information retrieval tasks. the average recall level precision of the model using the proposed approach is about 10 ? higher than that of traditional ones

    為了獲取詞語在文章中的語義權重,解決詞語的同義、多義模糊問題,提升信息檢索的效率,提出了一種基於概念的檢索模型,模型中設計了一種形式化的文本內容表示框架,框架由2部分構成:文章的"領域"以及"情景與背景"信息,並由概念(形式化語義)加以表示.同時,提出了提取該概念框架的方法,給出了用於框架與檢索要求間匹配的兩階段平滑演算法.實驗表明,在trec6提供的小規模語料集下,採用所提出方法的信息檢索模型與傳統模型相比,平均召回準確率提升了約10 ? ,效果顯著,充分說明了基於本文描述方法構建的、以概念作為處理中介的信息檢索系統的有效性和可行性

Through discussing such core technologies in the automatic processing of chinese information as automatic word segmentation, feature selecting and automatic representation of texts, the thesis makes some improvements and perfection on the current methods of automatic word segmentation and text space reduction of chinese texts, therefore improved their efficiencies and effects. with regard to the methods of text classification, the paper introduced two supervisory automatic classification methods of chinese texts based on multi - classification, i. e. fuzzy clustering and boosting, which settled the problem of low percentage of recall. through comparing the results of experiments with the two methods, an automatic classification system of multi - classification texts is constructed based on the boosting method, which received good effects in application and provides a good resolution to the problem of real - time classification of information

  7. For coping with this disadvantage, we put forward a sample selecting method without model. in this method, we selected a subset from unlabeled sentences which had a similar syntactic rule distribution to the set of all sentences, so the precision and recall of the parser trained by the labeled subset would be similar to the result of parser trained by all sentences, and the labor of labeling would be less

    因為這個子集包含的句法規則分佈能近似於原句子集的句法規則分佈,所以這個子集標注后訓練的句法分析器的精確率和召回率近似於用原句子集標注后訓練的句法分析器的精確率和召回率,而標注子集所需的人力比標注原句子集所需的人力小。
