The objective of SDI service is to reduce users' effort in their pursuit of relevant infomlation. However, the performance of SDI service based on simple matching of user interest profiles with new documents, has been inefficient. To improve the efficiency of such services agent based approaches are proposed. Collaborative filtering system is one type of agent teclmology that uses a database about user preferences to predict additional documents of items that the new user might like. It combines the opinions of humans to make personalized, accurate predictions. This study is therefore, an attempt to assess the applicability of collaborative filtering approach to SDI service. This report presents the basic ideas of collaborative filtering systems and describes the results obtained from a preliminary experiment conducted based on the data obtained from Intemational Livestock Research Institute's (ILRI) sm service. Finally, based on the experiment findings, recommendations for further research are forwarded.enInformation ScienceThesis
