Disclosed is a system for positioning a document in a browser at the point in the document where the answer to a given question is found. Traditional search engines return to the user a list of the top-matching documents. Sometimes the document title is accompanied by what is called a document abstract, but it just amounts to the first 200 or so characters of the docu- ment. It is often the case that not only does the title+abstract combination not answer the user's query, but it is still unclear whether reading the document will elicit the answer. The user must link to the document, and then proceed to read some or all of the document in order to discover if the answer is really there. In the context of a Question-Answering system, the system not only finds the best- matching documents, but specific passages within those documents that answer the query. When the user browses a document in the hit-list, our invention is to have the browser auto- matically scroll to the location of the matching passage position it around the center of the screen, for example and also to highlight the passage to make it stand out from the rest of the document. With this technique, the user can very quickly discover what the answer is, if it is present, of that there is no good answer to be found in the document. 1
