Are web users really Markovian?
2012
Proceedings of the 21st international conference on World Wide Web - WWW '12
Preserved Fulltext
Our main result invokes statistical order estimation tests for Markov chains to establish that Web users are not, in fact, Markovian. ...
User modeling on the Web has rested on the fundamental assumption of Markovian behavior -a user's next action depends only on her current state, and not the history leading up to the current state. ...
INTRODUCTION The Markovian model for Web user behavior posits that when a user is browsing a Web page P , the next page she visits depends only on P and not on how the user arrived at P . ...

The objective of this paper is to propose an approach that extracts automatically web user profiling based on user navigation paths. ...
Web user profiling consists of the best representative behaviors, represented by Markov models (MM). ...
In the data collections, we have a relation table with 200 attributes, and few of them are really useful to achieve our objective. ...

We assume that this phenomenon follows a Markovian law and most of the discussion is dedicated to the case of three quality conditions of each user, for which we characterize an optimal index policy and ...
It is really interesting to observe the way in which the different policies treat the two classes. ...

We first focus on three-state channels and show that threshold policies (of giving higher priority to users with higher transmission rate) are not necessarily optimal. ...
We consider Markovian channel dynamics, relaxing the common but unrealistic assumption of i.i.d. channels. ...
A class of users could, for instance, identify users located at the same physical properties (e.g. distance, obstacles), requesting to download the same type of file (e.g., video, mp3, web page, etc.), ...
