WHUIR at the NTCIR-12 Temporal Intent Disambiguation Task

WHUIR participated in the Temporal Intend Disambiguation (TID) Task of the Temporalia track at NTCIR-12. This paper describes our work of this specific subtask. Given a query, the task is to assign the probability value to four temporal classes i.e. Past, Recency, Future or Atemporal. Our overall strategy has been to rely on established off-the-shelf components (e.g., standard classifiers from LIBSVM and natural language processing methods from Stanford CoreNLP) and focus on feature discovering. We considered nineteen features in total from query itself. We used all the features for SVR in different parameter sets and chose the best three sets on the dry run data for the formal run. Results are presented and discussed in this paper.
