Abstract

Open source software development is becoming increasingly popular as a way of producing software, due to a number of factors. It is argued in this paper that these factors may have a significant impact on the future of information retrieval (IR) systems, and that it is desirable that these systems are made open to all. Some problems are outlined that may prevent the uptake of open source IR systems and a number of open source IR systems are described.
