【摘要】：各企業(yè)在進(jìn)行數(shù)據(jù)共享之前,首要考慮的是數(shù)據(jù)模型的數(shù)據(jù)映射關(guān)系,然而數(shù)據(jù)模型在不斷的更替與升級(jí),給數(shù)據(jù)集成帶來了很大困難。文中設(shè)計(jì)了一種對(duì)數(shù)據(jù)源結(jié)構(gòu)進(jìn)行統(tǒng)一描述的數(shù)據(jù)字典元模型,利用數(shù)據(jù)元來規(guī)范數(shù)據(jù)項(xiàng),將編輯距離算法思想應(yīng)用其中,實(shí)現(xiàn)數(shù)據(jù)項(xiàng)與數(shù)據(jù)元字典中數(shù)據(jù)元的相似度匹配。應(yīng)用語義樹的表示方法來描述數(shù)據(jù)元結(jié)構(gòu),利用語義相似度算法進(jìn)行數(shù)據(jù)元間的相似性、一致性檢查,尋找數(shù)據(jù)元間的關(guān)聯(lián)關(guān)系,間接地定位數(shù)據(jù)項(xiàng)間的語義關(guān)系,為數(shù)據(jù)映射奠定良好基礎(chǔ)。以中石化標(biāo)準(zhǔn)數(shù)據(jù)元規(guī)范油田企業(yè)搜索引擎數(shù)據(jù)項(xiàng),確保研究的實(shí)用價(jià)值。
[Abstract]:Before the enterprises share data, the first consideration is the data mapping relationship of the data model. However, the data model is constantly changing and upgrading, which brings great difficulties to the data integration. In this paper, a data dictionary meta-model is designed to describe the data source structure uniformly. The data element is used to standardize the data item, and the edit distance algorithm is applied to realize the similarity matching between the data item and the data element in the data element dictionary. The representation method of semantic tree is used to describe the data element structure, the similarity among data elements is checked by semantic similarity algorithm, the association relationship between data elements is searched, and the semantic relation among data items is indirectly located. Lay a good foundation for data mapping. The standard data element of Sinopec is used to standardize the data items of oil field enterprise search engine to ensure the practical value of the research.
