| Abstract | Determining the size of the World Wide Web is extremely difficult. The Web can be viewed as the largest data source available and presents a challenging task for effective design and access. One proposed Web mining approach to handling the problem of effective design and access is personalization. With personalization, Web access or the contents of a Web page are modified to better fit the desires of the user. This may involve dynamically creating Web pages that are unique per user or using the desires of a user to determine what Web documents to retrieve. This paper presents a Web mining model based on dynamic clustering and hidden Markov model. The output of the model is some information for dynamically creating a Web page which can best meet the user's desires. The assumption of the dynamic clustering is that if a group of users who have the same interest trend, those pages they have visited are probably related. We propose that human should be the authority to judge the correlation of two pages. First, the model statistic a user's Web browsing records in the log file; find a group of users who have the same interest trend with the user; collect all the pages in which this group of users are interested; calculate the correlation between pages; and cluster the pages into several categories according to a predetermined threshold. Each Web page category is considered as a stochastic state variable. In the second phase, our model based on hidden Markov model is further constructed to mine the latent desires of a user given an observed sequence of Web pages that the user have browsed. In order to get the optimal parameters (transition probability matrix, the conditional probability and the initial state) in the model, we applied the Baum-Welch parameter estimation method in EM algorithm to train the model on the data set. Experimental results show that the model is practicable and efficient |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
