Coordination of phrases of different syntactic categories has posed a problem for generative systems based only on syntactic categories. Although some prefer to treat them as exceptional cases that should require some extra mechanism (as for elliptical constructions), or to allow for unrestricted cross-category coordination, they can be naturally derived in a grammatic functional generative app...

grammatic representations in reasoning and problem solving sponsored by the American Association for Artificial Intelligence. The symposium brought together psychologists, computer scientists, and philosophers to discuss a range of issues covering both externally represented diagrams and mental images and both psychologyand AI-related issues. In this article, we develop a framework for thinking...

The pattern matching capabilities of neural networks can be mobilised for an automated, natural language, partial parser. First, language complexity is addressed by decomposing the problem into more tractable subtasks. Second, a representation is devised that enables effective, single layer networks to be used to map a pre-defined grammatic framework onto actual sentences. This paper examines d...

Executive summary We deal with the overall problem of mapping XML schemas to object models, where the resulting object models are meant for pro-grammatic, schema-aware access to XML data. The provision of such 'X-toO mappings' involves various challenges; one of them is variation in style of schema organization. Without appropriate countermeasures, such variation affects the resulting object mo...

This article presents the concept of School Dictionary Slovenian Language (ŠSSJ), which is being made as part project Spletni portal Franček, Jezikovna svetovalnica za učitelje slovenščine in Šolski slovar slovenskega jezika (Franček Web Portal, Counselling for Teachers and Language). The Language, a Franček portal, first specialized educational lexicographic-grammatic Slovenian, brings lexicog...

In the paper, we present the description of the Czech syntactic parser synt developed at FI MU NLP laboratory. The presented system is based on the meta-grammar formalism with a head-driven chart parser. The parsing technique provides fast analysis of the context free backbone with successive evaluation of the contextual constraints using so called “forest of values.” The meta-grammar formalism...

For the purposes of tool development, computer languages are usually described using context-free grammars with annotations such as semantic actions or pretty-printing instructions. These descriptions are processed by generators which automatically build software, e.g., parsers, pretty-printers and editing support. In many cases the annotations make grammars unreadable, and when generating code...

We present the issues involved in information obfuscation both for the embedding of information within digital signals and the detection of the hidden information. More standard cryptographic techniques acheive security through an encoding so that an evesdropper is unable to understand the signal. Obfuscation, preceded by an encoding, provides a method for the embedding of information within ot...
