摘要：Hidden Web�s broad and relevant coverage of dynamic and high quality contents coupled with the high change frequency of web pages poses a challenge for maintaining and fetching up-to-date information. For the purpose, it is required to verify whether a web page has been changed or not, which is another challenge. Therefore, a mechanism needs to be introduced for adjusting the time period between two successive revisits based on probability of updation of the web page. In this paper, architecture is being proposed that introduces a technique to continuously update/refresh the Hidden Web repository.
