Temporal questions

On the temporal interpretation of certain surprise questions

This article considers a special kind of surprise questions, i.e. those introduced by the adversative particle ma (but), and compares it with surprise exclamations. The main issue addressed here concerns the obligatory presence in the questions of the imperfect verbal form, versus the obligatory presence in exclamations of a non-imperfect indicative. It will be shown that the special semantics ...

Evaluation of Complex Temporal Questions in CLEF-QA

This paper presents the evaluation of a Temporal QA system for the treatment of temporal complex questions. The system was implemented as a multilayered architecture where complex temporal questions are first decomposed into simple questions, according to the temporal relations expressed in the original question. These simple questions are then processed independently by our standard Question A...

Splitting Complex Temporal Questions for Question Answering Systems

This paper presents a multi-layered Question Answering (Q.A.) architecture suitable for enhancing current Q.A. capabilities with the possibility of processing complex questions. That is, questions whose answer needs to be gathered from pieces of factual information scattered in different documents. Specifically, we have designed a layer oriented to process the different types of temporal questi...

A Preliminary Work on Classifying Time Granularities of Temporal Questions

Temporal question classification assigns time granularities to temporal questions ac-cording to their anticipated answers. It is very important for answer extraction and verification in the literature of temporal question answering. Other than simply distinguishing between "date" and "period", a more finegrained classification hierarchy scaling down from "millions of years" to "second" is propo...
