Abstract
(EN)
Information retrieval systems such as web search systems locate documents amongst millions and even billions of possible documents on the basis of query terms. In order to achieve this document indexes are created. We propose creating new fields in the documents to store feedback information. This information comprises query terms used in a particular search as well as information about whether a particular document retrieved is given positive or negative feedback for example. Indexes are created on the basis of this feedback information in addition to other available information. As a result relevance of search results is improved. Multiple fields of information are available for given documents (such as abstract fields, title fields, anchor text fields as well as our feedback fields). Any search algorithm which deals with multiple fields as well as multiple query terms and which provides for differential weighting of document fields is used.
