Problems related to indexicality, such as Sidelle's Answering Machine Paradox [10], have been problematic for direct reference theorists. the solutions suggested to date are not wholly satisfactory. I suggest that the correct solution requires an account of context shifting in natural language. However, existing context shifting accounts assume that context shifting is a purely semantic, operator-governed mechanism. this view has trouble dealing with so-called 'free shifts', such as the answering machine problem. I discuss these approaches and sketch a new account in terms of discourse context, which should be viewed as a pragmatic feature.

the paper addresses the problem of usingcontextual information by neural nets solving problems of contextual nature. the models of a context-dependent neuron and a multi-layer net are recalled and supplemented by the analysis of context-dependent and hybrid nets' architecture. the context-dependent nets' properties are discussed and compared withthe properties of traditional nets considering the VapnikChervonenkis dimension, contextual classification and solving tasks of contextual nature. the possibilities of applications to classification and control problems are also outlined.

GloBuddy is a dynamic broad-context phrase book that assists English speaking travelers in finding words and phrases, in a foreign language, that axe relevant to their current situation or context. Unlike traditional phrase books, such as Berlitz, GloBuddy achieves a broad range of contexts by using common sense knowledge from the OpenMind database and the OMCSnet, in conjunction with a translation program. When GloBuddy is launched on a hand-held device travelers will be able to turn to it for help in any context or situation.

context is vital for deciding which of the possible senses of a word is being used in a particular situation, a task known as disambiguation. Motivated by a survey of disambiguation techniques in natural language processing, this paper presents a mathematical model describing the relationship between words, meanings and contexts, giving examples of how context-groups can be used to distinguish different senses of ambiguous words. Many aspects of this model have interesting similarities with quantum theory.

the development of more and more complex distributed applications over large networks of computers has raised the problem of semantic interoperability across applications based on local and autonomous semantic schemas (e.g., concept hierarchies, taxonomies, ontologies). In this paper we propose to view each semantic schema as a context (in the sense defined in [1]), and propose an algorithm for automatically discovering relations across contexts (where relations are defined in the sense of [7]). the main feature of the algorithm is that the problem of finding relationships between contexts is encoded as a problem of logical satisfiability, and so the discovered mappings have a well-defined semantic. the algorithm we describe has been implemented as part of a peer-to-peer system for Distributed Knowledge Management, and tested on significant cases.

In this paper we will discuss the context management features of the new logic programming language DALI, aimed at defining agents and multi-agent systems. In particular, a DALI agent, which is capable of reactive and proactive behaviour, builds step-by-step her context. context update is modelled by the novel concept of "evolutionary semantics", where each context manipulation is interpreted as a program transformation step. We show that this kind of context-based agent language is well-suited for representing many significant commonsense reasoning examples.

Classical context Sensitive languages can be parsed by dynamically adding or removing production rules from the rules set. the grammar is modified according to the context, and evolves during parsing, allowing to take the context into consideration at the syntactical level and not in a separate semantic analysis. this approach has proven greater flexibility in the definition of programming languages, improving the readability and maintenability of program codes and the general usability of the language, thus improving the human-computer interaction. Examples of implementation of classical context sensitive languages as well as examples derived from practical applications are provided.
