LIG at CLEF 2016 Cultural Microblog Contextualization: TimeLine Illustration based on Microblogs
Résumé
This paper presents the approach used by the LIG-MRIM research group to the participation of the task 3 (TimeLine illustration based on Microblogs) for the CLEF of Cultural Microblog Contextualization track. This task deals with the retrieval of tweets related to cultural events (music festivals). For the content-based elements, we use the classical BM25 model [4]. Then, we diversify the results based on duplicate removal, using tf-based representations of tweets. In a third step, we apply optional re-ranking related to time-line, activity and popularity of authors of tweets.
