  1. The key to these issues is a proper context representation and reasoning model, which should satisfy the following requirements : 1 ) it should have the capability to deal with uncertainties, which is an intrinsic property of context ; 2 ) it should be first - order, since we need to discuss at the level of entities, attributes and relations. this property is also necessary for representing generally applicable context reasoning knowledge. 3 ) it should have reasonable complexity, since the application wants to now the up - to - date context

    上述題的核心是目前缺乏一個良好形式化的上下文表示和推理模型,而這個模型必須滿足如下屬性: 1 )能處理由於傳感器的不可靠以及不確定的知識帶來的上下文的不確定性; 2 )具備一階( first - order )描述能力,這是因為上下文信息需要在實體的屬性和實體間的關系層次進行描述,同時這種能力也是使上下文推理知識具有通用性的基礎; 3 )合理的,因為應用查上下文時希望了解的是即時的情況。

    為滿足結構、大規模的xml數據管理需要,本文深入研究了xml信息檢索系統中的結構索引演算法設計和結構化查優化中的查代價估計題,以及查結果和查條件間的相關演算法,主要取得了4個方面的成果:第一,分析了已有的xml數據索引演算法中存在的題,提出了一種高效的動態xml結構索引演算法difx ,它採用動態後向結構相似性( d - bisimilarity )的概念,可以根據實際查需求以及索引最優化的要求動態決定索引中保存的結構信息。
