Towards Modular Development of Typed Unification Grammars
Development of large-scale grammars for natural languages is a complicated endeavor: Grammars are developed collaboratively by teams of linguists, computational linguists, and computer scientists, in a process very similar to the development of large-scale software. Grammars are written in grammatical formalisms that resemble very-high-level programming languages, and are thus very similar to c...
متن کاملTyped Unification Grammars
We introduce TFS, a computer formalism in the class of logic ibrmaiisms which integrates a powerful type system. Its basic data structures are typed feature structures. The type system encourages an objectoriented approach to linguistic description by providing a multiple inheritance mechanism and an inference mechanism which allows the specitication of relations between levels o[ linguistic de...
متن کاملInductive learning of lexical semantics with typed unification grammars
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...
متن کاملFormalization and Parsing of Typed Unification-Based ID/LP Grammars
This paper de nes uni cation based ID/LP grammars based on typed feature structures as nonterminals and proposes a variant of Earley's algorithm to decide whether a given input sentence is a member of the language generated by a particular typed uni cation ID/LP grammar. A solution to the problem of the nonlocal ow of information in uni cation ID/LP grammars as mentioned in Sei ert (1991) is in...
متن کاملA 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...
