Characterizing Search Behavior in Web Archives

Web archives are a huge source of information to mine the past. However, tools to explore web archives are still in their infancy, in part due to the reduced knowledge that we have of their users. We contribute to this knowledge by presenting the first search behavior characterization of web archive users. We obtained detailed statistics about the users’ sessions, queries, terms and clicks from the analysis of their search logs. The results show that users did not spend much time and effort searching the past. They prefer short sessions, composed of short queries and few clicks. Full-text search is preferred to URL search, but both are frequently used. There is a strong evidence that users prefer the oldest documents over the newest, but mostly search without any temporal restriction. We discuss all these findings and their implications on the design of future web archives.
