Formalisation method for the text expressed knowledge

This paper describes a method of knowledge representation as a set of text expressed statements. The method is based on the identification of word-categories/phrases and their semantic relationships within the observed statement. Furthermore, the identification of semantic relationships between words/phrases using wh-questions that clarify the role of the word/phrase in the relationship is described. A conceptual model of the computer system based on the formalization method of text-expressed knowledge is proposed. The subsystem text formalization is described in detail, especially its parts: syntactic analysis of the sentence, sentence formalization, phrase structure grammar and lexicon. The phrase structure grammar is formed by induction and it is used to generate the language of the formalized notation of a sentence. The derivation of grammar is based on the simple phrase structure grammar which was used for the syntactical analysis of informal language notation. In its base, the suggested method translates sentences of the informal language into formal language sentences which are generated by the derivated phrase structure grammar. Current limitations of the method that also set the path of its further development are shown. Next concrete steps in the development of the method are also described.

Intelligent question — Answering systems: Review of research

With the development of ICT the need for automated question-answering systems is becoming increasingly important. Question-answering systems are still under development and experimentation. This paper is an overview of the research area that deals with question-answering systems; it explains the concept of question-answering systems and points out the problems that occur during their development. It also refers to a complex assessment techniques that are necessary when designing such systems. The system described is a real system and so are the test results.

Application of analytic hierarchy process (AHP) to measure the complexity of the business sector and business software

The paper shows a proposition of metrics for measuring the complexity of the business sector and business software. The metrics is based on a subjective estimation of complexity of the elements from the structure of business sector or business software, and reaching conclusions on the final complexity through the Analytic Hierarchy Process (AHP). Defined in this manner, the metrics represents a unique metrics for measuring the complexity of elements of business sector and business software, which enables their comparison. Due to this, the paper also shows possible situations between the measured complexities. The paper also presents a short overview of existing metrics for measuring the complexity of business sectors and business software.

The meaning and relationship of relevant elements in business organisation structure

One of the factors for reaching competitive advantage is establishing a corresponding business organisation structure which will be able to support its existence in the world of general globalisation processes. A modern approach to the establishment of such a structure is observing it from the viewpoint of its business processes. This paper tries to define the meaning and relation of relevant elements which contribute the dynamics of a business system and information elements which are being transformed in the process.

A Comparison and the Desireable Features of Version Control Tools

The software development team is regularly faced with two major problems: access to previous software versions and simultaneous work of many programmers on the same source code at the same time. Some development teams solve these problems by using version control tools, while others opt for manual version control. This paper analyzes both approaches and compares them according to certain criteria.

Model of a system for team software development

The paper describes a program support system for team development in a computer network environment. Existing program solutions already on the market are encapsulated and are not adapted to the needs of users working in an application development team. The objective is to develop a model of the system supporting a network application development. Along with the features providing application development in a network environment, the project solution includes facilities for producing various reports, automatic backup and version control

Comparison of Two Versions of Formalization Method for Text Expressed Knowledge

The Node of Knowledge (NOK) method is a method for knowledge representation. It is used as a basis for development of formalism for textual knowledge representation (FNOK). Two versions of formalization methods and, respectively, two Question Answering (QA) systems are developed. The first system uses grammars; it is written and implemented in Python. The second, improved system is based on storing text in relational databases without losing semantics and it is implemented in Oracle.

A Proposition for Classification of Business Sectors by ERP Solutions Support

This paper illustrates the results of an analysis of business sectors covered by ERP solutions. The authors answer questions in regards to business sectors supported by ERP solutions, while presenting a list of supported business sectors. Using a statistical analysis, an answer is given to the question of whether there are any business sectors that are supported by a large number of ERP solutions, and whether it is possible to classify business sectors based on the occurrence of the support. Finally, three classifications are described that stem from different statistical views of covering business sectors by ERP solutions, and a suggestion for a unique classification of business sectors is given.

Design phase of information systems integration process

A method of integrating separated information subsystems of a business system in a single information system is described. The problems of an integration process are analyzed as well as the problems concerning separated information subsystems. For successful integration, the process of planning a data model is important. On the basis of an integral data model, it is possible to construct an integrated database.

Adjective representation with the method Nodes of Knowledge

The paper analyzes the semantics of adjectives in sentences in English language. The goal is, based on the analysis of individual sentences and the method of induction, to show the semantic relationship between the adjective and other word types by using the method Nodes of Knowledge (NOK). The NOK method is used for formal knowledge representation expressed in text, i.e. to represent the knowledge network. The method incorporates the enrichment of representation with hidden semantics contained in the context of an individual sentence. The paper analyzes and graphically represents the location of the adjective in a sentence using the NOK method diagram (DNOK). DNOK graphically shows the knowledge network, which can be computer-implemented into the knowledge base as a part of the construction of intelligent information systems. The construction of intelligent information system is not possible without a complete metamodel of language and this work is a contribution to the research.
