Leveraging the Legacy of Conventional Libraries for Organizing Digital Libraries

Abstract

With the significant growth in the number of available electronic documents on the Internet, intranets, and digital libraries, the need for developing effective methods and systems to index and organize E-documents is felt more than ever. In this paper we introduce a new method for automatic text classification for categorizing E-documents by utilizing classification metadata of books, journals and other library holdings, that already exists in online catalogues of libraries. The method is based on identifying all references cited in a given document and, using the classification metadata of these references as catalogued in a physical library, devising an appropriate class for the document itself according to a standard library classification scheme with the help of a weighting mechanism. We have demonstrated the application of the proposed method and assessed its performance by developing a prototype classification system for classifying electronic syllabus documents archived in the Irish National Syllabus Repository according to the well-known Dewey Decimal Classification (DDC) scheme.
