Research And Implementation Of Keyword Query Module In Wording Unified Dictionary System

International activities of the large communication company has been growing athigh speed, meanwhile the text data also growing exponentially.XMLis becomingstandard form in online description and exchange information, and is widely used inQualcomm BREW platform, data card platform and many other application platformand product line. The validity of XMLdocuments retrieval has become an importantresearch direction.XML keyword query has recently becomea research hotspotofXMLdata queries.Main thesisare listed in following: This thesis developed with the background ofWording unified dictionary tool project. First The related technical features of BREWplatform and related concepts and technologies of XML that used for projectdevelopment is introduced.The whole frame is programed by the analysis of systemrequirements.An important part of the project is completed in the functional design, thatwas design and implementation of search module in Wording unified dictionarydatabase keyword, the implement of the module mainly depended on a search algorithm,this algorithm The algorithm is characterized by high efficiency and high precision.Finally, effectiveness and efficiency of XML keyword query methods and the traditionalkeyword search methods MLCA are experimental compared. Proved the superiority ofthe XML keyword query algorithm.At present, the project has been completed and put into the internal use incompany,and the reaction is good.Over millions of dollars can be saved every year byusing it.
