Emphasis at this point needs to be on the basic business classes, i. e. classes that correspond to objects as these are of relevance in the domain. the assumption is that in general these classes will lead to a related entity in the data model and as such can serve as a basis for sizing

Just as most of the natural language process technologies, the methods of ner have two classes, statistic - based and rule - based. considering of the limitation of using only one of the methods, we combined both of the methods to recognize named entity in this thesis. we combined the maching learning with ner to make the system get the ability of self - learning. we have done research on decision tree of maching learning mainly and designed a recognize model to recognize named entity. this model first used the probability and statistic way to extract the potential named entities, and then some context linguistic language information are employed in the model to recognize the named entities furtherly. as the wrong entites are denied, the recongnize effect has been improved
鑒于單獨採用基於統計方法或基於規則方法的缺陷，在這篇論文中，採用了統計與規則相結合的方法來識別命名實體。為了使系統具有學習能力，我們把機器學習方法應用於中文命名實體的識別，這里我們著重研究了機器學習中的決策樹方法在中文命名實體識別中的應用;設計了一種基於決策樹的識別模式，該模式首先利用概率統計方法，在文本中盡量完備地識別出潛在的命名實體，然後利用潛在命名實體相關的上下文詞法、語法和語義特徵作為屬性構建決策樹，否定不正確的實體，進一步提高了命名實體識別的準確率。 -
Rather than supporting direct mapping of object - oriented classes and properties to relational tables and columns, the entity framework maps relational tables, columns, and foreign key constraints to entities and relationships in conceptual models
與直接將面向對象的類及其屬性映射成關系型數據表和列不同，實體框架將數據庫內的關系表、列以及外鍵約束映射成概念模型里的實體和關系。 -
