2nd Temporal Web Analytics Workshop (TempWeb02) April 17th 2012 with WWW 2012 in Lyon, France.

New: Great attendance and presentations at TempWeb02, thanks to all!. Papers are now available at ACM DL and presentations will be available soon.


Time is a key dimension to understand the web. It is fair to say that it has not received yet all the attention it deserves and TempWeb is an attempt to help remedy this situation by putting time as the center of its reflexion.

Studying time in this context actually covers a large spectrum, from dating methodology to extraction of temporal information and knowledge, from diachronic studies to the design of infrastructural and experimental settings enabling a proper observation of this dimension.

For its second edition, TempWeb includes 6 papers out of a total of 17 papers submitted which put it's acceptance rate at 35%. The number of papers submitted has almost doubled compared to the first edition, which we like to interpret as a clear sign of positive dynamic and an indication of the relevance of this effort.
The workshop proceedings will be published in ACM DL (ISBN 978-1-4503-1188-5).

We hope you will find in these papers, the keynotes and the discussion and exchanges of this edition of TempWeb some motivations to look more into this important aspect of Web studies.
