Evaluation campaigns ![Top](lechani_files/fleche-montante.gif)
- TREC Microblog : The Microblog track examines search tasks and evaluation methodologies for information seeking behaviors in microblogging environments.
- TREC Medical Record Retrieval : The goal of the Medical Records track is to foster research on providing content-based access to the free-text fields of electronic medical records.
- CLEF Medical Image Retrieval : ImageCLEF aims to provide an evaluation forum for the cross–language annotation and retrieval of medical images and text-based medical information retrieval.
- CLEF Living Lab :Living labs is a new evaluation paradigm for information retrieval (IR), where the idea is to perform experiments in situ, with real users doing real tasks using real-world applications.
- TREC temporal summarization : The goal of the TREC Temporal Summarization Track is to develop systems for efficiently monitoring the information associated with an event over time.
