Modeling of Time and Document Aging for Request Prediction - One Step Further

By Ernst-georg Haffner, Uwe Roth, Thomas Engel and Christoph Meinel


An important problem of prediction algorithms is the treatment of document aging and the change in user request behavior. This paper proposes a possibility to model time in a standard prediction scenario and analyses the results in a test environment. The knowledge of characteristics in the generated test sessions is also applied to real user logs to determine explicit values of implicit access log information. With this technique, client server communication on the Internet should be improved. Keywords Prediction, Internet performance, document aging. 1. INTRODUCTION As reaction to the steady growth of the WWW, several methods to decrease user-perceived latency have been introduced. Prediction on server-side or client-side - carefully applied - is one possibility to improve Internetapplication performance. The idea of predicting future events originates from compiler construction and "Very large database"-design (VLDB) and is now being applied to Internet applications [12]. Many..
