LIG-MRIM at NTCIR-12 Lifelog Semantic Access Task

Résumé

This paper describes the participation of the LIG-MRIM research team to the Lifelog Semantic Access sub-task of the NTCIR-12 (2016). Our approach mainly relies on mapping the query terms to visual concepts computed on the Lifel-ogs images according to two separated learning schemes. A post-processing is then performed if the topic is related to temporal, location or activity information associated with the images. The results obtained are promising for a first participation to such a task, with event-based MAP above 29% and an event-based nDCG value close to 39%.
