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However, in the context of attribute initializers and assignments the named instances of the expression s type are introduced into the lexical scope with weaker visibility than variables and attributes and may be referenced with their unqualified names, for example
然而,在屬性初始化程序和賦值的上下文中,表達式類型的命名實例被引入到了詞法作用域lexical scope可見性弱於變量和屬性,並可以通過使用它們的無限定名unqualified names引用這些命名實例:Then it presents the design of information push service based on agent by using artificial intelligence technique. a brief introduction of each function module in this system and their internal transaction sequence are followed. the detail design and implement of key parts in each module is also given, which includes setting up user interest model with vector space model, searching information by using word segmenting and searching engine, filtering information using sorting algorithm, ordering information using pagerank algorithm
本文首先分析了傳統的信息「拉取」方式存在的主要問題以及推送技術的產生;然後結合人工智慧領域的agent技術,提出了基於agent的信息推送服務的總體設計,並簡要闡述了各功能模塊的內部處理流程和思想;接著給出了各模塊的詳細設計與實現,主要包括:利用向量空間模型( vectorspacemodel )建立用戶興趣模型,通過分詞並與搜索引擎協作實現信息檢索,採用分類演算法對已檢索的信息進行過濾,用pagerank演算法對信息排序。The main work is as follows : 1. introduce the main thoughts in overall designs of the chinese intelligent input method based on grammar and semantics, present its overall structures and make clear the functions of its function models. meanwhile, briefly introduce the collocation repository 、 grammatical repository and semantic repository used in this input method ' s core algorithms, provide the definitions needed for algorithm descriptions
