Information Retrieval and the Data Science Research Center

  1. 1. DS RC Data Science Research Center Information Retrieval Maarten de Rijke
  2. 2. DS RC Information retrieval • Information retrieval: computational methods for analyzing, understanding and enabling effective human interaction with information sources • Search engines: the most visible instantiation of information retrieval theories, models and algorithms
  3. 3. DS RC Information retrieval • Analysis – Content, Structure, Semantics, Behavior • Synthesis – Aggregation, fusion, learning to rank • Evaluation – Offline evaluation, user-centered studies, online evaluation
  4. 4. DS RC Local highlights • Analysis – Ranking social content (sentiment, ―framing‖, reputation, personality traits) – Semantic search (entities, events) – Online classification – Log analysis with external partners (blog, multimedia, location, …) • Synthesis – Online learning to rank – Data fusion – Aggregated search / vertical search • Evaluation – Interleaving – Automatic generation of test sets
  5. 5. DS RC Where is information retrieval located? Visual Analytics Business Analytics Decision Theory Understand and decide Distributed Processing Data Reasoning Knowledge representati on Large Scale Databases Store and process Software Eng. System / Network Eng. Analyze and model Multimedia Retrieval Modeling and simulation Information Retrieval Machine Learning
  6. 6. DS RC What is next? The most interesting way to view the world, is live
  7. 7. DS RC What’s next? • Real-time search • Ranking and aggregation with subjective criteria — sentiment, framing, personality • Self-learning search engines — through naturally occurring interactions with users • ―I am the query‖ • See our demo
