Abstract
The Open Archives Initiative (OAI) is an experimental initiative for the interoperability of Digital Libraries (DLs) based on metadata harvesting. The goal of OAI is to develop and promote interoperability solutions to facilitate the efficient dissemination of content. At present, however, there are still several challenging issues such as metadata incorrectness, poor quality of metadata, and metadata inconsistency that have to be solved in order to create a variety of high-quality services. In this paper we propose an integrated DL system with OAI and self-organizing capabilities. The system provides two value-added services, cross-archive searching and interactive concept browsing services, for organizing, exploring, and searching a collection of harvested metadata to satisfy users’ information needs. We also propose a multi-layered Self-Organizing Map (SOM) algorithm for building a subject-specific concept hierarchy using two input vector sets constructed by indexing the harvested metadata collection. By using the concept hierarchy, we can also automatically classify the harvested metadata collection for the purpose of selective harvesting.
