{"product_id":"ontology-based-semantic-data-integration-von-marcello-leida","title":"Ontology-based Semantic Data Integration","description":"\u003cp\u003eThis book embraces several aspects of Data  Integration, focusing on semantic heterogeneity. A first step toward solving the problem of semantic  heterogeneity is to formally specify the meaning of  the terminology used in the integration system and  to use that definition to access the integrated  information. Ontologies are the most promising technology to  achieve this aim. Real Time data translation is obtained through a  mapping which contains the necessary instructions  about the localisation of the information, the  assembling directives and how the final data is  presented. Therefore, the quality of mapping reflects accuracy  and reliability of the data integration system. This book provides several contributions to research  in data integration systems: starting from the  architectural point of view, we define a system  based on several ontologies that are used to  describe the meta-data involved in the different  integration steps. A novel formalisation of mapping language, able to  deal efficiently with different data semantics is  then presented, along with an innovative approach to  automatically generate the mapping schema.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838358819\"\u003e\u003ch3\u003eAn ontology based approach to semi-automatic real time data intergration and query from multiple  heterogeneous sources\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838358819","offer_id":39498895294557,"sku":"9783838358819","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/2a304e74-ebdc-417c-9aba-b223238c76f9.jpg?v=1757655796","url":"https:\/\/shop.autorenwelt.de\/products\/ontology-based-semantic-data-integration-von-marcello-leida","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
