چکیده

Work on the interpretation of temporal expressions in text has generally been pursued in one of two paradigms: the formal semantics approach, where an attempt is made to provide a well-grounded theoretical basis for the interpretation of these expressions, and the more pragmaticallyfocused approach represented by the development of the TIMEX2 standard, with its origins in work in information extraction. The former emphasises formal elegance and consistency; the latter emphasises broad coverage for practical applications. In this paper, we report on the development of a framework that attempts to integrate insights from both perspectives, with the aim of achieving broad coverage of the domain in a well-grounded manner from a formal perspective. We focus in particular on the development of a compact notation for representing the semantics of underspecified temporal expressions that can be used to provide component-level evaluation of systems that interpret such expressions.

A New Interpretation of the Semantics of "Moral Obligation" from Allame Tabatabaie's Viewpoint

The most important part in analyzing moral concepts includes those used as predicate in moral sentences covering moral concepts of valuation and obligation. Moral concepts in the field of values include those like “good” and “bad” while obligatory concepts include “ought to” and “ought no” and “duty”. Many papers have been written about “moral obligation”; however, dissociating the area of sema...

A Rule Based Approach to Temporal Expression Tagging

In this paper we present the DANTE system, a tagger for temporal expressions in English documents. DANTE performs both recognition and normalization of the expressions in accordance with the TIMEX2 annotation standard. The system is built on modular principles, with a clear separation between the recognition and normalisation components. The interface between these components is based on our no...

A Compositional Semantics of Temporal Expressions in English

This paper describes a compositional semantics for temporal expressions as part of the meaning representation language (MRL) of the JANUS system, a natural language understanding and generation system under joint development by BBN Laboratoires and the Information Sciences Institute. 1 The analysis is based on a higher order intansional logic described in detail in Hinrichs, Ayuso and Scha (198...

The Semantic Representation of Temporal Expressions in Text

Temporal expressions—references to points in time or periods of time—are widespread in text, and their proper interpretation is essential for any natural language processing task that requires the extraction of temporal information. Work on the interpretation of temporal expressions in text has generally been pursued in one of two paradigms: the formal semantics approach, where an attempt is ma...
