Exploiting the Functionality of Object-Oriented Database Management Systems for Information Retrieval

In this paper, we present the approach of FIRE to utilizing an object-oriented Database Management System (DBMS) for Information Retrieval (IR) purposes. First, a comprehensive overview of previous attempts to use DBMSs for implementing IR systems is given. Next, di erences between DBMSs and IR systems, with regard to indexing and retrieval, are discussed. In addition, some shortcomings of DBMS...
