The Design and Implementation of Parallel Digital Library Management System

As the number of documents in digital library grows, it becomes increasingly difficult to store, manage the large amount of documents and finding requested relevant documents by users. Parallel Digital Library management System (PDLS) is used for this purpose. PDLS is a general tool for building and managing digital libraries of all kinds of documents to meet user needs. It implements system management and query processing in parallel. The functions of PDLS include data collection, format standardization, information extraction, automatic classification, data loading, data maintenance, query processing, external data entering, personalized recommendation etc. This study introduces the design and implementation of PDLS.
