The study of temporal dynamics and its impact can be framed within the so-called temporal IR approaches, which explain how user behavior, document content and scale vary with time, and how we can use them in our favor in order to improve retrieval effectiveness.

This half-day tutorial will outline research issues with respect to temporal dynamics, and provide a comprehensive overview of temporal IR approaches, essentially regarding processing dynamic content, temporal information extraction, temporal query analysis, and time-aware retrieval and ranking. The tutorial is structured into two sessions. During the first session, we will explain the general and wide aspects associated to temporal dynamics by focusing on the web domain, from content and structural changes to variations of user behavior and interactions. We will begin with temporal indexing and query processing. Next step, we will explain current …
