Keyword Spotting is a well-known method in document image retrieval. In this method, Search in document images is based on query word image. In this Paper, an approach for document image retrieval based on keyword spotting has been proposed. In proposed method, a framework using relevance feedback is presented. Relevance feedback, an interactive and efficient method is used in this paper to imp...

We study in this paper how explicit user feedback can be used by a case-based reasoning system to improve the quality of its retrieval phase. More specifically, we explore how both ranking feedback and relevance feedback can be exploited to modify the weights of case features. We propose some options to cope with each type of feedback. We also evaluate, in an interactive setting, their impact o...

Development assistance has a chequered past, in large part because planning for development assistance is historically such a fractured enterprise internally, and so disassociated from development assistance recipients’ assets and needs. The authors of environment-shaping offer an alternative development programme planning methodology that highlights above all else the ever-important relationsh...

In this paper we will describe Berkeley’s approach to the ImageCLEFphoto task for CLEF 2007. Once again (as in ImageCLEFphoto for CLEF 2006) we used entirely text-based methods for retrieval. For some runs this year, however, we exploited the basic similarity of the topics and database from 2006 to acquire the metadata descriptions of the “example images” in the 2007 queries, and used that meta...

Abstract. This paper presents a case-based reasoning (CBR) approach to provide adaptive support in microworlds. Interaction in microworlds is complex and unstructured, making the analysis of student behaviour difficult and the provision of computer-based feedback challenging. Our approach starts with the ellicitation of expected solutions to microworld tasks (both valid and common mistakes) to ...

abstract the extent to which teachers’ written corrective feedback (wcf) is conducive to esl learners’ improvement has been discussed since truscott’s claim in 1996. the mentioned debate continues because there has been lots of contrastive research studies with different results. this paper presents the results of a 2-month study of the effectiveness of wcf to 65 low intermediate iranian learne...
