چکیده

In the last decade machine learning techniques based on logic such as Inductive Logic Programming (ILP) have started being used in learning grammars from corpora. While the first approaches were based on the translation of grammar into first-order predicate logic, an attempt has been made recently to adapt the ILP learning schema to the feature constraint logic of typed-unification grammars. In this framework, the learner applies in turn generalisation and specialisation to the typed feature structures representing the grammar in order to improve its coverage of the training corpus provided. In this paper we demonstrate how the lexical resource WordNet could be incorporated into an existing grammar learning tool and show how lexical semantic constraints could be learned on the basis of the ontology information.

A Framework for Inductive Learning of Typed-Unification Grammars

LIGHT, the parsing system for typed-unification grammars [3], was recently extended so to allow the automate learning of attribute/feature paths values. Motivated by the logic design of these grammars [2], the learning strategy we adopted is inspired by Inductive Logic Programming [4]; we proceed by searching through hypothesis spaces generated by logic transformations of the input grammar. Two...

The role of Persian causative markers in the acquisition of English causative verbs

     This project investigates the relationship between lexical semantics and causative morphology in the acquisition of causative/inchoative-related verbs in English as a foreign language by Iranian speakers. Results of translation and picture judgment task show although L2 learners have largely acquired the correct lexico-syntactic classification of verbs in English, they were constrained by ...

Integrating a Unification-Based Semantics in a Large Scale Lexicalised Tree Adjoining Grammar for French

In contrast to LFG and HPSG, there is to date no large scale Tree Adjoining Grammar (TAG) equiped with a compositional semantics. In this paper, we report on the integration of a unification-based semantics into a Feature-Based Lexicalised TAG for French consisting of around 6 000 trees. We focus on verb semantics and show how factorisation can be used to support a compact and principled encodi...

FCGlight: Making the bridge between Fluid Construction Grammars and main-stream unification grammars by using feature constraint logics

Fluid Construction Grammars (FCGs) are a flavour of Construction Grammars, which themselves are unification-based grammars. Its syntax is (only) up to certain extent similar to other unification-based grammars. However, it lacks a declarative semantics, while its procedural semantics is truly particular, compared to other unification-based grammar formalisms. Here we propose the re-definition o...
