Classification of Short Technical Texts Using Sugeno Fuzzy Inference System

Abstract

The paper presents the results of classification of the short technical texts on the purpose of instruments using fuzzy sets theory and fuzzy logic. An important stage in designing special-purpose technical systems is the choice of equipment with specific operational characteristics. The need to categorize short technical texts, which present a brief description of equipment, annotations, fragments of databases, appears due to the fact that information about the equipment found in thematic abstract collections, technical and design documentation or in contextual advertising is often not structured and scattered. The other problems are a large number of typos, incorrect word usage and definitions in the texts. Much attention is paid to the characteristics of the objects of research and to recording their specific features – a large number of technical terms, abbreviations, symbols. The classifying technique is described, the expediency of application of fuzzy inference of Sugeno system associated with fuzziness of the natural language, the simplicity of mathematical calculations in the course of the experiment. A Sugeno model combines the description of the objects of research in the form of linguistic rules and functional dependencies. This approach greatly facilitates the interpretation of classification results

Intelligent Fault Detection and Identification Approach for Analog Electronic Circuits Based on Fuzzy Logic Classifier

“…Statistical analysis functions, such as the mean, minimum, and maximum, are used to extract the features from the obtained circuit frequency responses, which represent the input for the fuzzy logic classifier. A fuzzification process is performed by defining the functions of a fuzzy membership for each input of the Sugeno fuzzy logic classifier [30]. In this process, the crisp values of each input are represented by linguistic labels by manually analyzing the values of the input functions for the different classes to define the triangular membership degree for each fuzzy input value.…”
