In the Inspire project we studied methods of Answer Set Programming on applications that are related with Interpreting Natural Language.
Principal Investigator (Project Manager): Peter Schüller
Duration: April 2015 to September 2017
Funding: Scientific and Technological Research Council of Turkey (TÜBİTAK) Program 3501
English Title: Interpreting Natural Language using Answer Set Programming, Inconsistency Management, and Relevance Theory
Turkish Title: Çözüm Kümesi Programlaması, Tutarsızlık Yönetimi, ve Bağıntı Kuramıyla Doğal Dilin Yorumlaması
Natural language is a very efficient form of communication: humans leave out many details when they use language because other humans can easily fill these details. As an example, ‘morning coffee’ means ‘coffee drunk in the morning’ while ‘morning newspaper’ means ‘newspaper read in the morning’, and humans understand that without effort although neither ‘drunk’ nor ‘read’ is visible in the text. This underspecification, often combined with a high ambiguity of natural language, is a big challenge for NLU systems. The Inspire project aims to advance scientific methods that allow computers to interpret natural language text with the goal of recovering its intended meaning.
An existing approach in that direction is the usage of background knowledge bases (WordNet, FrameNet) together with abductive reasoning. The idea of abduction is to find the best explanation for a given observed text input. In this project we want to build an improved NLU formalism based on Answer Set Programming (ASP).
ASP is a general purpose logic programming formalism that supports comfortable representation of knowledge and nonmonotonic reasoning (such as abduction). In an ASP program we describe a set of potential solutions and relationships/constraints between concepts. Based on such a representation, an ASP solver (a software tool) computes solutions that respect all specified relationships and constraints. ASP can handle circular knowledge without problems and allows for an efficient integration of external knowledge such as WordNet and FrameNet.
The project has been concluded successfully in 2017.
- Mishal Benz (Kazmi) was funded by the project and received her PhD degree in 2017.
- The First-Order Horn Abduction Framework was developed and published.
- The CaspR Coreference Resolution Adjudication Tool was created and published.
- Several publications in collaboration with DEMACS at University of Calabria on lazy instantiation of constraints in Answer Set Programming.
