Descriptive and Technical Study of Languages and Metadata Systems Used on the Web

Cristian Vasquez, 2002

Introduction

These days most of the web content is designed by humans to be read by themselves, forming a chaotic library from which knowledge is difficult and expensive to extract.

Distinct communities promote the use of the "Semantic Web," which adds representation to the Web, to be machine-processable. The idea is to establish channels for feasible processing, integration, and reuse of Information, betting as the extraction of knowledge of better utility to humans. The semantic Web would only be an extension of the existing Web, where the Information acquires meaning through the use of Metadata, which provides semantics to its content and enables automatic reasoning about the Information.
