This paper deals with normalization of language data from Early New High German. We describe an unsupervised, rulebased approach which maps historical wordforms to modern wordforms. Rules are specified in the form of context-aware rewrite rules that apply to sequences of characters. They are derived from two aligned versions of the Luther bible and weighted according to their frequency. The eva...

Stemming has been an influential part in Information retrieval and search engines. There have been tremendous endeavours in making stemmer that are both efficient and accurate. Stemmers can have three method in stemming, Dictionary based stemmer, statistical-based stemmers, and rulebased stemmers. This paper aims at building a hybrid stemmer that uses both Dictionary based method and rule-based...

Constraint Handling Rules (CHR) is a declarative rulebased concurrent committed-choice programming language. Petri nets are a well-known formalism for modeling and analysis of concurrent processes. We aim to develop a framework to exploit Petri nets as a tool for the modeling and analysis of CHR programs. In this paper, we show that place/transition nets can easily be embedded into CHR and we d...

This paper gives an overview of ongoing work on a system for the generation of NL descriptions of classes defined in OWL ontologies. We present a general structuring approach for such descriptions. Since OWL ontologies do not by default contain the information necessary for lexicalization, lexical information has to be added to the data via annotations. A rulebased mechanism for automatically d...

The main purpose of this paper is to demonstrate an empirical approach to social simulation. The systems and the behaviour of middle-level managers of a real company are modelled. The managers' cognition is represented by problem space architectures drawn from cognitive science and an endorsements mechanism adapted from the literature on conflict resolution in rulebased systems. Both aspects of...

3D flower models are important components for impressive virtual reality environments. However, flowers’ leaves or petals are 3D free curved-surfaces and they are very difficult to model. We present a user interface with which the user can easily model flowers using freehand sketches. The user interfaces for generation, transformation, and copy are specialized to model leaves and petals, and th...

This paper presents a technical approach for temporal symbol integration aimed to be generally applicable in unimodal and multimodal user interfaces. It draws its strength from symbolic data representation and an underlying rulebased system, and is embedded in a multi-agent system. The core method for temporal integration is motivated by findings from cognitive science research. We discuss its ...

Basically, medical diagnosis problems are the most effective component of treatment policies. Recently, significant advances have been formed in medical diagnosis fields using data mining techniques. Data mining or Knowledge Discovery is searching large databases to discover patterns and evaluate the probability of next occurrences. In this paper, Bayesian Classifier is used as a Non-linear dat...
