Abstract: | Database systems have many advantages for implementing document retrieval systems. One of the main advantages would be the integration of data and text handling in a single information system. However, it has not been clear how much a database implementation would cost in terms of efficiency. In this paper, we compare a database implementation and a stand-alone implementation of a flexible representation of the content of documents and the associated search strategies. The representation used is a network of document and index term nodes. The comparison shows that certain features of a database system can have a significant effect on the efficiency of the implementation. Despite this, it appears that a database implementation of a sophisticated document retrieval system can be competitive with a stand-alone implementation. |
