中文摘要 | 綱要映對是指將兩個綱要的元素做語意和結構上的對應,是綱要整合的重要工作,綱要映對在資料庫相關領域應用非常廣泛,例如:資料整合、電子商務、語意查詢處理等。以前大部份的綱要映對研究偏重在關聯式的資料模式上,較少對XML文件做處理。近年來順應全球資訊網的發展,愈來愈多研究偏重在XML文件以及 XML綱要DTD的轉換和映對上,但以XML Schema做映對的研究仍屬少數。而且大部份的綱要映對研究都是半自動產生映對,需要部份人工輔助。因此,本研究探討XML綱要映對的相關方法及問題,並以綱要映對為基礎,提出一個XML Schema的自動綱要映對架構,藉由XML Schema豐富的內容及混合的比對方法,更精確的比對出綱要之間的映對關係。 |
英文摘要 | Schema mapping, which is an important task of schema integration, makes elements of two schemas matching semantically and structurally to each other. Schema mapping is used widely in the relative domain of database, such as data integration, electronic commerce, semantic query processing and so forth. There are many researches in schema mapping. Most of them put great emphasis on relational data model but seldom on XML data model. Currently, the developing of the World Wide Web has increased the researches in XML document and in translating and mapping of DTD. But there are still few researches in mapping of XML Schema. Moreover, most schema mapping is typically performed manually, perhaps supported by auxiliary information. Therefore, we study the approaches and questions of XML Schema mapping and propose a schema-based approach, which can match XML Schema automatically. Through the rich content of XML Schema and the well-composed mapping approach, we can produce more accurate mapping results. |
