A conceptual framework Node of knowledge enables, among others, presentation of knowledge in a formalized record suitable for insert into a relational database. To correctly transform all words from natural language sentences to formalized records, it is necessary to design a metamodel of a language and define rules for transformation of each sente...

The paper describes the improvement of the system for automatic question answering based on the knowledge expressed in natural language sentences. The system is implemented using a relational database. This system will be the basis for the development of a web application for obtaining answers to the posed questions. In order for natural language s...

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). FNOK was used for development of a Question Answering (QA) System whose research results are presented in this paper. The QA system is based on storing text in relational databa...

Svakodnevnim korištenjem raznih softvera ljudi se susreću s pogreškama nastalim u procesu njihova razvoja. One mogu biti trivijalne, ali mogu biti i kritične za korištenje određenih funkcionalnosti softvera. Pogreške prilikom razvoja su neizbježne, zato se u testiranje softvera ulažu velike količine novca i vremena. No, unatoč velikom trudu i ulaga...

Verbalized text contains knowledge necessary and sufficient for transfer of numerous human cognitions. The question is how this knowledge was saved into text. Authors believe that they found an important idea how to assemble knowledge into nodes of knowledge. Similar methods in the field of knowledge networks exist, but none of them does it in the...

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 Pyth...

This paper presents the results of a research on implementation of online tests in e-course and the effort of their improvement in order to design the basis for formative and summative students' assessment. The research was conducted on Information Systems course at the Department of Informatics, University of Rijeka, and it included 335 students....

Rad opisuje razvoj sustava za prihvaćanje ljudskog pitanja u prirodnom jeziku od korisnika i pružanje jednog ili više točnih odgovora. Opisani sustav je dio većega sustava za upravljanje znanjima temeljenoga na Node of Knowledge (NOK) konceptualnom okviru. Prikazan je dio NOK konceptualnog okvira i u sklopu njega nova metoda prikaza znanja iskazano...

Knowledge representation is one of the areas covered by artificial intelligence. Method Nodes of Knowledge (NOK) is one of the methods which allows a graphical representation and organization of knowledge in the form of a DNOK diagram (Diagram of Nodes Of Knowledge) as a network of nodes. With this diagram the meaning of sentences is preserved. The...

This paper presents research results on transformation of database structure and its content into new representation by using the Node of knowledge method (NOK method). It describes the way an Entity-relationship model and its relational database can be transformed into a NOK model. The rules that enable this transformation of entity-relationship c...

This paper presents the results of a comparative research of paper-based testing versus online testing using MudRi. The research was conducted on three courses at the Department of Informatics, University of Rijeka, and included 1231 tests. In observed courses, online tests have largely replaced traditional paper-based tests in the last few years....

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...

U ovom radu ukratko je opisan model organizacije znanja na tri razine (jezično, opće i radno znanje) te metoda NOK (Nodes Of Knowledge) za organiziranje mreže znanja. NOK je metoda za predstavljanje znanja (engl. knowledge representation, KR). U radu se raspravlja odnos ljudskog znanja i objektivne stvarnosti te položaj i mogućnost organiziranja um...

This paper presents the results of a research on code merging in a specific development environment. The research data was collected during a timeframe of 5 years of software development and maintenance. Four different software products were monitored. During that time 49.572 procedure mergings occurred and 498 of them were recognized as conflicts....

The negative capacitance circuits are very interesting analog building blocks with many possible applications like the compensation of undesired parasitic capacitance, bandwidth enhancement of amplifiers, equalization filters design without passive inductors, etc. This paper presents a method for improving and controlling CMOS floating negative cap...

A low-energy CMOS Successive Approximation Register (SAR) ADC dedicated for use in wireless sensor networks is presented. Wireless sensor networks (WSN) are built with individual nodes which sense, compute and communicate, and operate with extremely limited energy. The crucial component of such network nodes is an ADC which acts as interface betwee...

The article shows a proposition of a metrics for measuring the size and contributions of ERP solutions through the number of covered business sectors. The size is defined as a feature which shows to what extent the ERP solution participates in covering business sectors, while contribution is a feature which shows to what extent the ERP solution con...
