Aiming at this problem, the main research issues and achievements in this paper are as follows : bi - directional data transformation between rdb and xml with semantic constraints preserved for most of existing researches on static data transformation between xml and rdb, dtd is taken as the schema description language for xml, and the semantic constraints are often lost during the transformation process. to overcome these disadvantages, the author adopts xml - schema, a standard schema description language proposed by w3c to replace dtd, as the description method owing to its more powerful functions than dtd, and of course with the syntax much more complicated. after analyzing the constraints characteristics in both xml - schema and relational schema, a semantic constraints - preserved algorithm is proposed which can realize the bi - directional schema mapping between rdb and xml through a formalized description of xml based on regular tree and a general expression for relational schema based on direct graph approach
保留語義約束的xml與rdb雙向靜態數據轉換技術現有研究大多採用dtd （ documenttypedefinition ，文檔類型定義）作為xml的模式描述語言，並且在模式映射過程中丟失語義約束信息，本文分析了xml - schema （ xml - schema採用與dtd完全不同的語法，數據描述能力更強同時也更為復雜，已被w3c確定為替代dtd作為xml模式描述語言的標準）及關系模式的語義約束特徵，通過基於正則樹的xml形式化描述方法以及基於有向圖的一般關系模式表示方法的研究，建立保留語義約束的xml - schema與關系模式的雙向模式映射演算法，實現了xml與rdb的雙向數據轉換，較好地解決了xml與rdb在靜態數據轉換層面的數據集成問題，可有效滿足企業大量rdb數據面向xml的發布以及與日俱增的xml數據存入rdb的應用需求。 -
Traditional coding algorithms are based on simple n - gram models. those distant constraints and some redundancies in natural language, such as word order redundancies, semantic redundancies and syntactic redundancies, are neglected in the n - gram models. in order to find and reduce those redundancies, we need more intelligent algorithms based on more effective models
通用無損數據編碼是數據壓縮領域的一個重要的分支，現有的無損數據編碼方法大多是基於n - gram模型的， n - gram模型忽略了自然語言中的遠距離約束和諸如詞序冗餘、語義冗餘、句法冗餘等冗餘，為了找出並減少這些冗餘，需要更有效的語言模型和更智能的演算法。 -

The relax ng compact syntax provides a much less verbose, and easier to read, format for describing the same semantic constraints as relax ng xml syntax
Relax ng緊湊語法提供了一種格式用於描述與relax ng xml語法相同的語義約束，這種格式更簡潔、更易於閱讀。 -
This bug occurs when stored data fails to satisfy certain syntactic or semantic constraints ; when software crashes due to an error, not in the coding, but in the data the code is manipulating
這種錯誤在已存儲的數據不能滿足某些句法或語義約束時發生；此時軟體會因為代碼操縱的數據中的錯誤而不是編碼中的錯誤而崩潰。 -
Constraints of lexical tones on semantic activation on the recognition of spoken words in chinese were investigated in three cross - modal priming lexical decision experiments
摘要進行了三個跨通道啟動詞匯判斷實驗，探討漢語聽覺詞匯加工中聲調信息對語義激活的制約作用。 -
Verifying the soundness of the uml statecharts model can be translated into the verification of the soundness of the global reachable state transition diagram, and the algorithms verifying the soundness and the properties of semantic - related are given. at the aspect of verifying the consistency of temporal constraints of workflow, the time events are added into the uml statecharts, then the rules translating the extended uml statecharts into timed automata are given. the upper constraints ( the most time interval between two tasks ), lower constraints ( the least time interval between two tasks ) and deadline constraints are defined by tctl. the consistency of these constraints in build time, instantiation time and run - time are defined respectively
在驗證工作流時序約束一致性方面，在uml狀態圖中加入了時間事件，給出了將擴展后的uml狀態圖轉化為時間自動機的規則，用時間計算樹邏輯定義了兩個任務間的最大、最小時間間隔（上、下界約束）和工作流的最終期限約束，並給出了這三類約束分別在創建階段、實例化階段和運行階段的一致性定義，通過alur的演算法對時序約束一致性進行驗證。 -
