Data mining service for OAIster digital library

Abstract

OAIster is a digital library with more than 10 million resources - one of the largest repositories in the world. It supports two search methods: ordinary web-based search and the SRU search-retrieve protocol which returns metadata in BibClass format. Unfortunately with SRU, the OAIster database search is quite time-consuming and only single keyword queries are supported. The goal of this paper is to present new web service for searching in OAIster repository. The service is based on the SQI web service and allows multi keyword search. It is currently implemented in the ObjectSpot search engine but it might be used in any other service which supports SQI and RSS 2.0 data formats. The results and comparison with SRU client are evaluated in this paper. © 2008 IADIS.
