Synopsis

Temporal web dynamics and how they impact upon various components of information retrieval (IR) systems have received a large share of attention in the last decade. In particular, the study of relevance in information retrieval can now be framed within the so-called time aware IR approaches, which explain how user behaviour, document content and scale vary with time, and how we can use them in our favour in order to improve retrieval effectiveness. This book provides a comprehensive overview of time-aware IR approaches, centred around the following questions: what are temporal web dynamics, why do they occur, and when and how to leverage temporal information throughout the search cycle and architecture. It first explains the general and wide aspects associated to temporal web dynamics, from content and structural changes to variations of user behaviour and interactions. Next, it pinpoints several research issues and the impact of such temporal characteristics on search, essentially regarding processing dynamic content, temporal query analysis and time-aware ranking.It also addresses particular aspects of temporal information extraction (how to timestamp documents and generate temporal profiles of text). To this end, it presents existing temporal search engines and applications in related research areas, e.g., exploration, summarization, and clustering of search results, as well as future event retrieval and prediction, where the time dimension also plays an important role.
