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.

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 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.

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.

Methods and software for estimation of information system dependability

Information system dependability reflects the users degree of confidence in the system. Todays ICT allows connections between information systems in different applications and in different geographic locations. These information systems are called dependable because connections between them cause certain events in one information system to be reflected in the other. Therefore, it is important to have a method for the estimation of information system dependability that will be used in the information system development phase. This estimation will provide arguments for a possible modification of information systems before their final commissioning. The purpose of this paper is to provide an overview of the methods and software for the estimation of information system dependability. Five qualitative and two quantitative methods for estimation of information system dependability are presented. A list of ten estimation software it has been made and five of them are presented in detail.

Estimation of the Size of Business Sectors Covered by ERP Solutions

The paper describes a method for estimation of the size of business sectors covered by ERP solutions. It presents a short overview of existing methods for measuring the size of business sectors and software in general, including the ERP solution as its special type. A list of business sectors which are supported by ERP solutions is given. The described method for the estimation of size was applied over this business sectors list. Then, an estimation of the number of common elements which are part of the structure of the observed business sectors was performed. Based on the estimated number of common elements and estimated size of business sectors, the relationship between common and specific elements in the size of business sectors supported by ERP solutions was calculated.
