Locating passages using a case-base of excerpts

We present the SPIRE system, a hybrid case-based reasoning (CBR) and information retrieval (IR) system. It relies on a small case-base to seed the IR system to 1) select documents that are relevant to a presented problem case, and then (2) highlight within these retrieved documents passages that contain relevant information about specific case features. SPIRE aids not only problem-solving but knowledge acquisition by focusing a text extractor---person or program---on areas of text where needed information is likely to be found. Once extracted, this information can be used to create new cases or data-base objects thus closing the loop in the problem-solving---knowledge-acquisition cycle. 1 Introduction When confronted with a new problem, we frequently try to relate it to one that we have dealt with previously. If we have knowledge of a similar prior problem, we might try to apply the same or a related solution. Similarly, we might want to evaluate a scenario and hypothesize the likeli...
