System and method used to provide fast and accurate retrieval of findings results from large amounts of report documents (the corpus), such as medical record documents. The system maintains a dynamic list of the characteristics of no-finding called no-finding descriptors, each identified by a tag. Upon entering the corpus, the sentences of each new document are searched, and each sentence the content of which is similar to one of the descriptors is tagged. When search is conducted, the user enters a word or phrase, which expresses the subject of search. This subject is searched for in the corpus and from which a list of all sentences that contain the subject - the initial result list. This initial results list includes both finding and no-finding results. The final result list is obtained by extracting from the initial result list all occurrences of the tagged no-finding sentences. |
