| Abstract | This paper proposes a rule based web image annotation method which improves the precision and recall of annotation by the use of decision tree. This decision tree learns the relationship between images and their annotations based on the proposed 17 attributes that specify the structural relationship between them in HTML documents and the visual characteristics of the images. By converting and pruning this learned tree, a set of rules with high estimated accuracy which determines whether or not a word can be the keyword of an image can be generated. Upon experimental results, the proposed method made 57 rules and the precision and recall of annotation by these rules were about 88% and 95% for the various concepts, respectively. We argue the contribution of this work in two aspects. First, we suggest the clear criteria for precise annotation inferred by the statistical analysis of many web pages. Second, to cope with the deterioration of recall caused by the lack of measure for the visual characteristics, the visual similarity between an image and its concept combines to the attributes that used for tree learning. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
