In this paper, we deal with editing tabular forms for program specifications based on a particular graph grammar HNGG [2]. First, we formalize syntax-directed editing methods by extending of the notion of the Cornell Program Synthesizer [8] to attribute NCE graph grammars (cf. [1]). Next, we discuss the algorithms of the editing methods. keyword Graph Grammars, Visual Programming, Software Deve...

The 200 million word corpus of the Bank of English was annotated morphologically and syntactically using the English Constraint Grammar analyser, a rulebased shallow parser developed at the Research Unit for Computational Linguistics, University of Helsinki. We discuss the annotation system and methods used in the corpus work, as well as the theoretical assumptions of the Constraint Grammar syn...

We present a relational learning framework for grammar induction that is able to learn meaning as well as syntax. We introduce a type of constraint-based grammar, lexicalized well-founded grammar (lwfg), and we prove that it can always be learned from a small set of semantically annotated examples, given a set of assumptions. The semantic representation chosen allows us to learn the constraints...

We present an approach to multilingual web content based on multilingual grammars and syntax editing for a controlled language. Content can be edited in any supported language and it is automatically kept within a controlled language fragment. We have implemented a web-based syntax editor for Grammatical Framework (GF) grammars which allows both direct abstract syntax tree manipulation and text...

Visual programming languages use pictures as programs. One approach to building a visual programming environment is to parameterlze a generic environment with a language specification. We describe a mechanism for specifying visual languages that can be used as the basis of a language-independent visual programming environment. Our mechanism is a new type of grammar, called a picture layout gram...

What roles do syntax and semantics have in the grammar of a language? What are the consequences of these roles for syntactic structure, and why does it matter? We sketch the Simpler Syntax Hypothesis, which holds that much of the explanatory role attributed to syntax in contemporary linguistics is properly the responsibility of semantics. This rebalancing permits broader coverage of empirical l...
