Keeping a Digital Library Clean: New Solutions to Old Problems
Alberto Laender, Universidade Federal de Minas Gerais, Brazil
Abstract: Digital Libraries are complex information systems that involve rich sets of digital objects and their respective metadata, along with multiple organizational structures and services such as searching, browsing and personalization, and are normally built having a target community of users with specific interests. However, keeping a digital library updated and consistent, particularly when its content is obtained from multiple and distinct sources, is not a trivial task. In this talk, we address two problems usually faced when managing digital libraries of scientific publications: the disambiguation of author names and the search for the full-text of cataloged articles. We discuss the implication of these two problems to the quality of the services provided by a digital library and describe the solutions we have proposed to solve them.
