Kaynak Keşif Yeteneğinin Artırılması için İnternet Kaynaklarının İçeriklerinin Standart Biçimde Tanımlanması

Abstract

Since internet resources are not yet machine-understandable, there are some problems with satisfaction of information needs of users. Unstructural representation of resources and employing ad-hoc solutions for the issue of how to interpret these resources constitute the reasons that an eye would easily catch at first sight. Given that a drastic and staedy in­crease in the number as well as in the volume of lntemet resources has been obseNed over years, in addition to search engines based on content terms, the necessity of software agents being capable of automatically discovering and haNesting these resources has arisen. Success of this type of software agents very closely depends on standartization of mod­eling of resources to be processed. A semantic modeling defined as a re­sult of such an effort is called RDF (Resource Description Framework), and the studies on this model is controlled by WWW (World-Wide Web) Consortium. The DC (Dublin Core) metadata elements have been defined using the property of extensibility of RDF to handle electronic catolog in­formation. in this article, an authoring editor, called H-DCEdit, is intro­duced. This editor makes use of RDF/DC model to define contents of Turkish electronic resources. To serialize (or to code) a RDF model, SGML (Standard Generalized Markup Language) has been used. in addi­tion to this work, by using DSSSL (Document Style Semantics and Spec­ification Language) standard, the format information in regard to a given RDFIDC document has been separated from its content, and hence H­DCEdit provides different views of an RDFIDC document.
