An OAI-Based Filtering Service for CITIDEL from NDLTD

One goal of the Computing and Information Technology Interactive Digital Educational Library (CITIDEL) is to maximize the number of computing-related resources available to computer science scholars and practitioners through it. In this paper, we describe a set of experiments designed to help this goal by adding to CITIDEL a sub-collection of computing related electronic theses and dissertations (ETDs) automatically extracted from the Networked Digital Library of Theses and Dissertations (NDLTD) OAI Union Catalog. We analyze the metadata quality of the NDLTD OAI Union Catalog and describe three different experiments that combine different sources of evidence to improve the accuracy in filtering out the computing related entries.
