The Theory of K-representations as a Flexible Tool for Designing Natural-Language Interfaces of Recommender System

P. 6-10.
Fomichov V. A.

The paper describes a new method of constructing recommender systems with natural-language interface. This method is based on the theory of K-representations (knowledge representations) - a new theory of designing semantic-syntactic analyzers of natural language texts with the broad use of formal means for representing input, intermediary, and output data. The current version of the theory is set forth in a monograph (the author is V.A. Fomichov) published by Springer in 2010. The stated approach is implemented in the programming environment PHP + MySQL: an experimental recommender system has been developed.

Theory of K-representations as a Comprehensive Formal Framework for Developing a Multilingual Semantic Web
Fomichov V. A. Informatica. 2010. Vol. 34. No. 3. P. 287-296.

A comprehensive theoretical framework for the development of a Semantic Web of a new generation, or of a Multilingual Semantic Web, is outlined. Firstly, the paper grounds the possibility of using a mathematical model being the kernel of the theory of K-representations and describing a system of 10 partial operations on conceptual structures for building semantic representations (or text meaning representations) of, likely, arbitrary sentences and discourses in English, Russian, French, German, and other languages. The possibilities of using SK-languages defined by the theory of K-representations for building semantic annotations of informational sources and for constructing semantic representations of discourses pertaining to biology and medicine are illustrated. Secondly, an original strategy of transforming the existing Web into a Semantic Web of a new generation with the well-developed mechanisms of understanding natural language texts is described. The third subject of this paper is a description of the correspondence between the inputs and outputs of the elaborated algorithm of semantic-syntactic analysis and of its advantages; the semantic representations of the input texts are the expressions of SK-languages (standard knowledge languages). The input  texts can be the statements, questions, and commands from the sublanguages of English, Russian, and German. The algorithm has been implemented by means of the programming language PYTHON.

A Formal Model for Constructing Semantic Expansions of the Search Requests about the Achievements and Failures
Fomichov V. A., Kirillov A. V. In bk.: Artificial Intelligence: Methodology, Systems, and Applications. 15th International Conference, AIMSA 2012, Varna, Bulgaria, September 12-15, 2012. Proceedings. Iss. 7557. Heidelberg; Dordrecht; L.; NY: Springer, 2012. P. 296-304.

The paper describes a new method of constructing semantic expansions of search requests about the achievements and failures of active systems (organizations, people) for improving the results of Web search. This method is based on the theory of K-representations (knowledge representations), proposed by V.A. Fomichov - a new theory of designing semantic-syntactic analysers of natural language texts with the broad use of formal means for representing input, intermediary, and output data. The method uses an original formal model of a goals base – a knowledge base containing the information about the goals of active systems. The stated approach is implemented with the help of the Web programming language Java: an experimental search system AOS (Aspect Oriented Search) has been developed and tested.

The prospects revealed by the theory of K-representations for bioinformatics and Semantic Web
Fomichov V. A. In bk.: Actes de la 18e conference sur le Traitement Automatique des Langues Naturels. Actes de la 15e Rencontre des Etudiants Cercheurs en Informatique pour le Traitement Automatique des Langues. France, Montpellie, 27th June - 1st July 2011. Vol. 1: Actes: articles longs. Montpellier: AVL Diffusion, 2011. P. 5-20.

The paper describes the structure and possible applications of the theory of K-representations (knowledge representations) in bioinformatics and in the development of a Semantic Web of a new generation. It is an original theory of designing semantic-syntactic analyzers of natural language (NL) texts with the broad use of formal means for representing input, intermediary, and output data. The current version of the theory is set forth in a monograph by V. Fomichov (Springer, 2010). The first part of the theory is a formal model describing a system consisting of ten operations on conceptual structures. This model defines a new class of formal languages – the class of SK-languages. The broad possibilities of constructing semantic representations of complex discourses pertaining to biology are shown. A new formal approach to developing multilingual algorithms of semantic-syntactic analysis of NL-texts is outlined. This approach is realized by means of a program in the language PYTHON.
