It has been hypothesized that Tree Adjoining Grammar (TAG) is particularly well suited for sentence generation. It is unclear, however, how a sentence generation system based on TAG should choose among the syntactic possibilities made available in the grammar. In this paper we consider the question of what needs to be done to generate with TAGs and explain a generation system that provides the ...

The paper presents a grammar for anisotropic two-dimensional mesh adaptation in hp-adaptive Finite Element Method with rectangular elements. It occurs that a straightforward approach to modeling this process via grammar productions leads to potential deadlock in h-adaptation of the mesh. This fact is shown on a Petri net model of an exemplary adaptation. Therefore auxiliary productions are adde...

Developing a Tree Adjoining Grammar which contains the information necessary for building the basic compositional semantics of sentences is a highly complex engineering task. To ensure consistency, ease of writing, of maintainance and of debugging, it is therefore important that this information be described at the appropriate level of abstraction. In the first part of this paper (sections 2 an...

Linguistic utterances are full of errors and novel expressions, yet linguistic communication is remarkably robust. This paper presents a double-layered architecture for open-ended language processing, in which ‘diagnostics’ and ‘repairs’ operate on a meta-level for detecting and solving problems that may occur during habitual processing on a routine layer. Through concrete operational examples,...

Research in the origins and evolution of language has now reached a level where languages with grammatical structures are emerging in computer simulations and robotic experiments based on situated embodied language games played by populations of agents. This paper focuses on some of the technical AI issues related to this research. Specifically, we report on a system for planning complex meanin...

This paper presents a Logic Programming approach to parsing and production in Fluid Construction Grammar (FCG) [13]. It builds on previous work on the formalisation of FCG in terms of First Order Logic (FOL) concepts, more specifically on the definition of its core inference operations, unification and merge, in terms of FOL unification and search in the space of a particular set of FOL terms c...

This chapter has two objectives. It discusses a design pattern for phrasal constructions and introduces the templates that can be used to instantiate this pattern in Fluid Construction Grammar, using as illustration nominal phrases such as “the green mouse” or “this mouse of mine”. Phrasal constructions not only build phrases but also combine the meanings contributed by their constituents and p...

proceeded difference in opinion of grammarians led to the capacity of thought in grammar of arabic language, and cause to the conflict in thought of the grammarians. this research aims to study the difference between grammarians in modern grammatical matters, which is similar to that difference that took place between grammarians in basra and kufa in matters of arabic grammar. the present resea...

A dialogue system can present itself and/or address the user as an active agent by means of linguistic constructions in personal style, or suppress agentivity by using impersonal style. We compare system evaluation judgments and input style alignment of users interacting with an in-car dialogue system generating output in personal vs. impersonal style. Although our results are consistent with e...
