Keyword Spotting is a well-known method in document image retrieval which is based on query word image. In this paper, a document image retrieval system based on keyword spotting and relevancefeedback is presented. Relevance feedback as an interactive method is used in this paper to improve theperformance of Document Image Retrieval System (DIRS). In the proposed method, we compare several strategies of positive and negative feedbacks which include Only Positive Feedback , Only Negative Feedback and Positive and Negative Feedback .
