An Object-Oriented Framework for Developing Information Retrieval Applications

Abstract. Design and development of information retrieval (IR) systems is a complex and expensive process. In the process of building an IR system, developers need to explore a large design space: on the one hand, they have tochoose from a plethora of IR techniques developed due to the signi cant advances made in theoretical and experimental research in information retrieval; on the other hand, many of these techniques need to be tailored to the particular application in hand. Hence, an IR system implementation tool which allows exploration and composition of di erent IR system components 1 is very valuable in building e ective and e cient IR systems. To construct such a tool, we need to develop modular and extensible IR components such that these components can be used in a mix and match fashion. This paper describes an extensible and modular framework which can be used to construct IR applications.

An Object-Oriented Framework for Developing Information Retrieval Applications on Digital Libraries

Abstract. Design and development of information retrieval (IR) systems is a complex and expensive process. In the process of building an IR system, developers encounter a large design space: on the one hand, they have tochoose from a plethora of IR techniques developed due to the signi cant advances made in theoretical and experimental research in information retrieval; on the other hand, many ofthese techniques need to be tailored to the particular application in hand. Hence, an IR system implementation tool which allows exploration and composition of di erent system strategies is very valuable to build e ective and e-cient IR systems. To build such a tool, we need to develop modular and extensible IR components such that these components can be used in a mix and match fashion.This paper describes an extensible and modular framework which can be used to construct IR applications.
