Overview of NTCIR-11 Temporal Information Access (Temporalia) Task

Abstract

This paper describes the overview of NTCIR-11 Temporal Information Access (Temporalia) task. This pilot task aims to foster research in temporal aspects of information retrieval and search. Temporalia is composed of two subtasks: Temporal Query Intent Classication (TQIC) and Temporal Information Retrieval (TIR) subtask. TQIC attracted 6 teams which submitted a total of 17 runs, while 6 teams took part in TIR proposing 18 runs. In this paper we describe both subtasks, datasets, evaluation methods and results of meta analyses.
