Gathering Metadata from Web-Based Repositories of Historical Publications
نویسندگان
چکیده
In this paper we examine the problem of extracting schema-conforming metadata out from HTML sources. A technique founded on semistructured data analysis is explained. It is based on the combination of HTML styles, which abstract the visual characteristics of documents, and document-oriented context-free grammar, which provide structural information. This technique is flexible enough to be applied not only on individual HTML docuements, but also on hyperlinked web structures. This provides an informed, very controlled way of navigating the repositories.
