The memory capacities for auto-and hetero-associative incompletely connected memories are calculated. First, the capacity is computed for xed parameters of the system. Optimization yields a maximum capacity between 0.53 and 0.69 for hetero-association and half of it for auto-association, improving previous results. The maximum capacity requires sparse input(More)
As more and more knowledge and information becomes available through computers, a critical capability of systems supporting knowledge management is the classification of documents into categories that are meaningful to the user. In a step beyond the use of keywords, we developed a system that analyzes the sentences contained in unstructured or(More)
As the second part of a special issue on “Neural Networks and Structured Knowledge,” the contributions collected here concentrate on the extraction of knowledge, particularly in the form of rules, from neural networks, and on applications relying on the representation and processing of structured knowledge by neural networks. The transformation of the(More)
This paper describes a platform-independent application for the monitoring of distributed applications. The tool is intended for system administrators to properly distribute the components of a distributed application onto particular machines. An essential part of this tool is based on intelligent mobile agent technology used to access the target systems.(More)
This paper proposes the design and implementation of a context-based free text interpreter (CFTI), a computer-based natural language understanding (NLU) system that can handle text as generated and used by humans, within a given context. It takes advantage of tracking the contextual meaning of words and phrases during (and after) the development of an(More)
Knowledge representation and reasoning methods in artificial intelligence almost exclusively rely on symbol-oriented methods: Statements describing aspects and objects of the system to be modelled are represented through symbols (mostly text strings), and these symbols are stored in a computer, and manipulated according to the inference rules prescribed by(More)
