In this paper we present Grammatic – a tool for textual syntax definition. Grammatic serves as a front-end for parser generators (and other tools) and brings modularity and reuse to their development artifacts. It adapts techniques for separation of concerns from ApsectOriented Programming to grammars and uses templates for grammar reuse. We illustrate usage of Grammatic by describing a case st...

Grammatic is a tool for grammar definition and manipulation aimed to improve modularity and reuse of grammars and related development artifacts. It is independent from parsing technology and any other details of target system implementation. Grammatic provides a way for annotating grammars with arbitrary metadata (associativity attributes, semantic actions or anything else). It might be used as...

A new approach to ambiguity of context-free grammars is presented, and within this approach the LL and LR techniques are generalized to solve the following problems for large classes of ambiguous grammars: |Construction of a parser that accepts all sentences generated by the grammar, and which always terminates in linear time. |Identiication of the structural ambiguity: a nite set of pairs of p...

OBJECTIVE To investigate the cognitive and neural basis for nonfluent speech in progressive nonfluent aphasia (PNFA). BACKGROUND Nonfluent speech is the hallmark feature of PNFA, and this has been attributed to impairments in syntactic processing, motor-speech planning, and executive functioning that also occur in these patients. Patients with PNFA have left inferior frontal atrophy. METHOD...

grammatic's miracle of the qur'an as a new topic has been studied in this paper. this miracle means that there are the words and phrases in the quran having two or more grammatic states in point of viow of scholars in arabic literature. so that, firstly, all the aspects of sense are accepted and seem reasonable and acceptable and secondly, in light of these states, different meanings ...

The present study is a practical guide to editors who refine partially machine-translated text as a basis for linguistic analysis. The posteditors' tasks are: to code preferred English equivalents, to code English structural symbols, to resolve grammatic properties, and to code syntactic connections (dependencies). A general introduction to the field of machine translation is contained in The R...

The pattern matching capabilities of neural networks can be used to locate syntactic constituents of natural language. This paper describes a fully automated hybrid system, using neural nets operating within a grammatic framework. It addresses the representation of language for connectionist processing, and describes methods of constraining the problem size. The function of the network is briee...

We derive the two-particle fluctuation correlator in a thermal gas of π-mesons to the lowest order in an interaction due to a resonance exchange. A dia-grammatic technique is used. We discuss how this result can be applied to event-by-event fluctuations in heavy-ion collisions, in particular, to search for the critical point of QCD. As a practical example, we determine the shape of the rapidity...
