This article describes a method used to calculate the similarity between short English texts, specifically of sentence length. The described algorithm calculates semantic and word order similarities of two sentences. In order to do so, it uses a structured lexical knowledge base and statistical information from a corpus. The described method works well in determining sentence similarity for mos...

This paper proposes using fuzzy logic techniques to dynamically control parameter settings of genetic algorithms (GAs). We describe the Dynamic Parametric GA: a GA that uses a fuzzy knowledge-based system to control GA parameters. We then introduce a technique for automatically designing and tuning the fuzzy knowledgebase system using GAs. Results from initial experiments show a performance imp...

Ali Akbar Dehkhoda, the prominent lexicographer, describes a person who has difficulty in grasping knowledge as someone who “Cannot understand something without knowing all its details.” If the knowledge required by somebody is in a language other than the person’s mother tongue, access to this knowledge will surely meet special difficulties resulting from the person’s lack of mastery over the ...

We present a general framework for an adaptive, user-interactive design support system. Adaptability requires the acquisition and usage of huge amounts of highly structured knowledge. Interactiveness, i.e., the ability to perform and react in tight co-operation with the user, is of special importance in complex domains like industrial building design. Case-based learning will be applied to prov...

This thesis presents a knowledge-based system for composition of piano minuets in early classical style (e.g. young W.A. Mozart). The problem takes an intermediate position between restricted and free problems of computerized composition of music. The composition process is split into 3 subtasks: structure planning, melody composition and bass composition. The structure plan consists of two lev...

This report presents a design method for decision rules called ARD+. It is an extension of a previously proposed ARD method. In ARD+ the emphasis is put on the gradual refinement of the conceptual model of a knowledge-based system described with attributes. A practical algorithm providing a transition from the ARD+ design to rule design is introduced. Using ARD+ and the algorithm it is possible...

The aim of this paper is to present a probability measure associated to the set of complex formules of P (set of single logic propositions), CP. This probability measure will be used in the construction of heuristic algorithms in Artificial Intelligence problems. Throughout this work it will be seen how Knowledge Base Systems (KBS) act when they receive incomplete information. Calculation of KB...

How to measure gain from the use of intelligent inference ? How can the complexity of the recognition/ classification task be estimated? What is the type of evidence which best suits an .inference mechanism? These questions are addressed here in their theoretical and methodological aspects. Their practical implications are demonstrated with 'real' crop mapping task. For this purpose, simple rul...

Nesting algorithms deal with the optimal placement of shapes in specified regions subject to specified constraints. In this paper, a complex algorithm for solving two-dimensional nesting problem is proposed. Arbitrary geometric shapes are first quantized into a binary form. These binary representations are subsequently processed by operators which nest the shapes in a rectangle of minimum area....
