It process documents not only based on latent semantic analysis, but also based on text multilevel dependency structure. the method first analysis the latent semantic structure of texts, make single value decomposition on text - matrix, reconstruct the semantic matrix ; then a method based on text multilevel dependency structure is adopted, deeply analysis the content of the semantic matrix, abstract the important sentences to generate abstraction and make up the shortage of latent semantic analysis on structure and syntax
首先通過對文本進行潛在語義分析，對文本矩陣進行相應的奇異值分解，重構語義矩陣;然後採用基於篇章多級依存結構的文摘分析方法，對重構的語義矩陣表示的文本內容進行深入的分析，抽取重要的句子生成文摘，這樣就彌補了潛在語義分析在詞法和句法分析上的不足;同時過濾和去除了語義噪音，縮小了問題的規模。 -

First, by analysing the disadvangtages of the decomposition and recovery algorithm in the usual security model, a new algorithm of double structure tables, which is suitble for master - slaver structure tables, is presented in this paper. second, in resolving the semantic ambiguity and operational incompleteness easily emerged in master - slaver structure tables, an improved master - slaver structure table model and relative decomposition and recovery algorithm are provided. third, considering the merits and demerits of security model, a multilevel secure transaction model is defined on the basis of security model
本文通過分析以往安全模型的分解和恢復演算法的缺點，提出了一個適合於主從結構表這種雙結構表安全模型的分解和恢復演算法;針對主從結構表安全模型容易產生語義模糊性和操作不完備性等問題，提出了一個改進的主從結構表安全模型，並提出了其分解和恢復可行方法;討論了安全模型的優缺點，定義了建立在安全模型基礎之上的多級安全事務模型，分析了多級事務面臨的眾多難題，提出了一個安全、正確的多級事務調度演算法;根據上述的諸多理論，開發了一個多級安全數據庫管理系統的原型系統。
