SCOUT is an expert system designed to aid the practicing physician in searching a full-text database of biomedical literature for information in the domain of oncology. In the clinical setting, an information-retrieval system needs to provide only a few relevant documents that address a patient-specific query. SCOUT models the expertise of an oncologist and an information specialist in a probabilistic inference system; it applies expert heuristics both in selecting the best source of information for a particular question and in developing an effective, source-specific search statement that retrieves only a minimal number of pertinent documents.
SCOUT是一个专家系统，旨在帮助执业医师在生物医学文献全文数据库中搜索肿瘤学领域的信息。在临床环境中，信息检索系统只需提供几份与患者特定查询相关的文档。SCOUT在概率推理系统中对肿瘤学家和信息专家的专业知识进行建模；它在为特定问题选择最佳信息源以及制定有效的、针对特定信息源的搜索语句时应用专家启发式方法，该搜索语句只会检索极少量相关文档。
