Formal Foundations of Constraint-Based Semantics for Natural Language
In this project I am developing a framework for a formal semantics which
permits fine grained distinctions of meaning that can account for some
of the inferential properties of natural language. I am constructing a
family of intensional logics that allow for a distinction between equivalence
and identity, and so does not reduce logical equivalence to intensional
identity. These intensional logics provide languages of semantic representation.
The system which I am developing is intended to provide the basis for a
viable computational semantics that can be integrated into a constraint-based
grammar. The project is funded by grant RG AN2687/APN9387 from the Arts
and Humanities Board Research Board of the UK. It includes Howard Gregory
as a post-doctoral research assistant and Christian Ebert as a part-time
research assistant. Two papers that describe the work being done in this
project are (with Chris Fox) A
Framework for the Hyperintensional Semantics of Natural Language with Two
Implementations and (with Carl Pollard)
Strategies
for Hyperintensional Semantics .
Phrasal Utterance Resolution in Dialogue (with Jonathan Ginzburg)
We are developing an implemented system for interpreting fragments in
dialogue within a type feature structure framework. We are building on
the results of earlier work on ellipis resolution in HPSG which I did with
Howard Gregory in the SOAS
Ellipsis Project, and Ginzburg's
previous research on modelling dialogue. More information on our HPSG dialogue
project can be obtained from the project
site. The project is funded by grant R000222969 from the Economic and
Social Research Council of the UK. It includes Raquel Fernandez as a part-time
research assistant. The following papers present different aspects of the
project: (with Jonathan Ginzburg and Howard Gregory) SHARDS:
Fragment Resolution in Dialogue and (with Christian Ebert,
Howard Gregory, and Nicolas Nicolov) Generation
of Fragment Paraphrases in Dialogue.
