Text retrieval in Norway

Abstract

After discussing the characteristics of text retrieval systems, their development is outlined. An explanation is given of the information requirements of lawyers in relation to legal databases. The work undertaken by the Norwegian Research Centre (NRCCL) is described. Details are given of the use made of STATUS and the redesigned version subsequently called NOVA*STATUS, which has been used to run various services as part of the NORIS (previously JURIS) research programme for text retrieval systems. Various research results from the NORIS work are described. Details are given of the controlled experiments in evaluating text retrieval systems performance and the ways of formulating searches. Results are discussed in terms of precision and recall. A particular feature of the investigations relate to the use of ranked output and the criteria for ranking. A new software package called SIFT is how being developed for use on a NOR minicomputer, in the light of the experiences with STATUS and the NORIS research results. 17 refs.
