Abstract

Purpose

The purpose of this paper is implementation of a software system for bibliographic material processing which does not require knowledge about any format for bibliographic data input. This means that the input can be done not only by librarians, but also by other persons such as authors of bibliographic units, students, employees, etc.

Design/methodology/approach

An object‐oriented methodology for developing information systems by means of computer‐aided software engineering (CASE) tools and software components is used. The software architecture is multi‐layered and web‐based. The implementation is done in Java environment.

Findings

The result is a web application by which users can catalogue bibliographic material without being familiar with the corresponding format. Nevertheless, the bibliographic record is formed in accordance with the given format for bibliographic material processing (MARC21, UNIMARC, etc.).

Research limitations/implications

Automatic generating of screen forms for the chosen set of data for bibliographic material processing is not provided in the presented version of the application. In order to eliminate this limitation, there are preset solutions that can be integrated into the application.

Practical implications

The application is primarily intended for research institutions aiming at forming their electronic catalogue and/or bibliographies of researchers or institutions.

Originality/value

The originality of the paper lies in the software architecture of the application related to the middle layer, i.e. the one of business logic. This layer implements a mechanism by which different sets of input data are mapped to persistent data by means of the unique object model of an accepted format for the bibliographic material processing (MARC21, UNIMARC, or others).

Abstract

Purpose

The aim of this paper is to develop a system for automatic extraction of metadata from scientific papers in PDF format for the information system for monitoring the scientific research activity of the University of Novi Sad (CRIS UNS).

Design/methodology/approach

The system is based on machine learning and performs automatic extraction and classification of metadata in eight pre‐defined categories. The extraction task is realised as a classification process. For the purpose of classification each row of text is represented with a vector that comprises different features: formatting, position, characteristics related to the words, etc. Experiments were performed with standard classification models. Both a single classifier with all eight categories and eight individual classifiers were tested. Classifiers were evaluated using the five‐fold cross validation, on a manually annotated corpus comprising 100 scientific papers in PDF format, collected from various conferences, journals and authors' personal web pages.

Findings

Based on the performances obtained on classification experiments, eight separate support vector machines (SVM) models (each of which recognises its corresponding category) were chosen. All eight models were established to have a good performance. The F‐measure was over 85 per cent for almost all of the classifiers and over 90 per cent for most of them.

Research limitations/implications

Automatically extracted metadata cannot be directly entered into CRIS UNS but requires control of the curators.

Practical implications

The proposed system for automatic metadata extraction using support vector machines model was integrated into the software system, CRIS UNS. Metadata extraction has been tested on the publications of researchers from the Department of Mathematics and Informatics of the Faculty of Sciences in Novi Sad. Analysis of extracted metadata from these publications showed that the performance of the system for the previously unseen data is in accordance with that obtained by the cross‐validation from eight separate SVM classifiers. This system will help in the process of synchronising metadata from CRIS UNS with other institutional repositories.

Originality/value

The paper documents a fully automated system for metadata extraction from scientific papers that was developed. The system is based on the SVM classifier and open source tools, and is capable of extracting eight types of metadata from scientific articles of any format that can be converted to PDF. Although developed as part of CRIS UNS, the proposed system can be integrated into other CRIS systems, as well as institutional repositories and library management systems.

Abstract

Purpose

The aim of this research is to define a data model of theses and dissertations that enables data exchange with CERIF‐compatible CRIS systems and data exchange according to OAI‐PMH protocol in different metadata formats (Dublin Core, EDT‐MS, etc.).

Design/methodology/approach

Various systems that contain metadata about theses and dissertations are analyzed. There are different standards and protocols that enable the interoperability of those systems: CERIF standard, AOI‐PMH protocol, etc. A physical data model that enables interoperability with almost all of those systems is created using the PowerDesigner CASE tool.

Findings

A set of metadata about theses and dissertations that contain all the metadata required by CERIF data model, Dublin Core format, EDT‐MS format and all the metadata prescribed by the University of Novi Sad is defined. Defined metadata can be stored in the CERIF‐compatible data model based on the MARC21 format.

Practical implications

CRIS‐UNS is a CRIS which has been developed at the University of Novi Sad since 2008. The system is based on the proposed data model, which enables the system's interoperability with other CERIF‐compatible CRIS systems. Also, the system based on the proposed model can become a member of NDLTD.

Social implications

A system based on the proposed model increases the availability of theses and dissertations, and thus encourages the development of the knowledge‐based society.

Originality/value

A data model of theses and dissertations that enables interoperability with CERIF‐compatible CRIS systems is proposed. A software system based on the proposed model could become a member of NDLTD and exchange metadata with institutional repositories. The proposed model increases the availability of theses and dissertations.

Abstract

Purpose

Entering data about published research results should be implemented as a web application that enables authors to input their own data without the knowledge of the bibliographic standard. The aim of this research is to develop a research management system based on a bibliographic standard and to provide data exchange with other research management systems based on the Common European Research Information Format (CERIF) data model.

Design/methodology/approach

Object‐oriented methodology was used for information system modelling. The modelling was carried out using the computer‐aided software engineering (CASE) tool that supports the Unified Modelling Language 2.0 (UML 2.0). The implementation was realised using a set of open‐source solutions written in Java.

Findings

The result is a system for managing data about published research results. The main system features are the following: public access via the web; authors input data about their own publications by themselves; data about publications are stored in the MARC 21 format; and the user interface enables authors to input data without the knowledge of the MARC 21 format.

Research limitations/implications

A method of verifying accuracy of entered data has not been considered yet. It is necessary to allow authorised persons to verify the accuracy of the data. After verifying the accuracy the authors cannot change the data.

Practical implications

This software system has been verified and tested on data about published results of researchers employed at the University of Novi Sad in Serbia. This system can be used for evaluation and reporting on scientific research results, generating bibliographies of researchers, research groups and institutions etc.

Originality/value

A part of the research management system for entering data about authors and published results is implemented. Data about publications are stored in a bibliographic format and authors can input data about their own publications without the knowledge of the bibliographic standard. The main feature of the system architecture is mutual independence of the component for interaction with users and the component for persisting and retrieving data from the bibliographic records database.

Abstract

Purpose

This paper aims to examine the goal, which is to construct a user interface for CERIF‐compatible research management systems in an automated way. The system has to support all data items defined by the CERIF data model. The result of the automated construction is a functioning software system that can be customised according to the specific needs by manual changes in the program code.

Design/methodology/approach

The Model‐Driven Architecture (MDA) approach to software engineering is based on the idea of automated construction of software applications based on the model of a system. System modelling usually utilises the Unified Modelling Language (UML). A specific UML profile (extension) used for describing user interface‐related aspects of the system model is defined. It is used to define the behaviour of the user interface in the model itself. By relying on the concept of a standard generic screen form implementing common data management operations and tools for automatic code generation it is possible to obtain a fully functional software application that is completely defined by the system model.

Findings

A proposal of an automated user interface construction method for CERIF‐compatible research management systems is defined. The proposed application enables the management of all CERIF‐specified data items and facilitates the customisation of the model according to the specific needs. The customisation process is automated by using the tools for user interface code generation based on human‐computer interaction (HCI) standard defining the layout and behaviour of generic screen forms. The amount of automatically generated application functionality justifies the use of the model‐driven approach to software development.

Practical implications

Using the model of a system it is possible to efficiently produce a functional software application that can further be customised according to the needs of specific institutions and users. The customisation process itself is made efficient since it is iteratively performed using the same cycles of modelling and software generation. The proposed method for automated user interface construction is used for implementing the web application for research management at the University of Novi Sad.

Originality/value

A proposal for efficient software system development and its customisation is given. This way a software application is obtained that can be quickly adapted to new requirements and used in different research management systems based on a CERIF‐compatible data model.

Abstract

Purpose

The aim of the research is modelling and implementation of a client application that enables parallel search and retrieval of bibliographic records from multiple servers. The client application supports simultaneous communication over Z39.50 and SRW/SRU protocols. The application design is flexible and later addition of other communication protocols for search/retrieval is envisioned and supported.

Design/methodology/approach

Object‐oriented approach has been used for modelling and implementation of client application. CASE tool, Sybase PowerDesigner, supporting Unified Modelling Language (UML 2.0), was used for modelling. Java programming language and Eclipse environment were used for implementation.

Findings

The result of the research is a client application that enables parallel search and retrieval of multiple Z39.50 and SRW/SRU servers. Additionally, the application supports conversion from type‐1 query language, defined by Z39.50 standard, to CQL query language required for search/retrieval from SRW/SRU servers. The application was verified by performing parallel search and retrieval from several publicly accessible Z39.50 and SRW/SRU servers.

Research limitations/implications

The application supports only the use of bib‐1 attribute set for type‐1 queries created according to Z39.50 standard. Hence, only such queries can be converted to CQL notation. The use of other attribute sets is not supported.

Practical implications

The client application is integrated into the BISIS software system, version 4. This enables the cataloguing of bibliographic records retrieved over Z39.50 and SRW/SRU protocol.

Originality/value

The contribution of this work is in client application architecture that enables parallel communication with multiple servers, which can use different communication protocols, Z39.50 or SRW/SRU. Search/retrieval from servers using some other protocol is also supported. This can be achieved by adding new classes that implement protocol specification, and classes for query transformation into notation required by that new protocol, if required.

Abstract

Purpose

The purpose of this paper is to model and implement an extensible markup language (XML)‐based editor for library cataloguing. The editor model should support data input in the form of free text with interactive control of structure and content validity of records specified in the UNIMARC and MARC 21 formats. The editor is implemented in the Java programming language in the form of a software package.

Design/methodology/approach

The unified modelling language (UML 2.0) is used for the specification of both the information requirements and the model architecture. The object oriented methodology is used for design and implementation of the software packages, as well as the corresponding CASE tools.

Findings

The result is an editor for UNIMARC and MARC 21 cataloguing. The editor is based on the XML technologies by which the two basic characteristics are achieved as follows: a possibility of integrating the editor into different library software systems and, moving to another format requires only the changes of the module for bibliographic record data control.

Research limitations/implications

A basic limitation of the system is related to the subsystem that controls validation of the bibliographic records and its expansion for work with other bibliographic formats. In the proposed solution, a part of the control of data input is included into the implementation itself and it is related to the UNIMARC format. That is, a part of data by which the control is done, such as repeatability of the record elements and the codebooks, is contained in the XML document of the format that is input information in the editor. However, the control that is related to validation of the format of content in record elements cannot be performed for any other format without modification in the implementation. Therefore, the research could be continued by considering the separation of data used for content control as input information for the application. In that way, this segment would also become implementation independent. One of the solutions should be extending the XML document of the format by this data. Some other solution should mean creating a totally separate system for the content validation. Moreover, the proposed editor supports processing of a bibliographic record only in the UNIMARC and MARC 21 formats. Processing of records in other formats requires considerable changes in the model.

Practical implications

The model of a new editor is developed on the basis of the experience and needs of electronic management in city and special libraries. Based on the given model a new editor is implemented and integrated into the BISIS software system used by the mentioned libraries. Testing and verification are performed on the bibliographic records of the public city libraries.

Originality/value

The contribution of this work is in the system architecture that is based on the XML documents and is independent of the bibliographic format. The XML document that contains data about the bibliographic format represents the editor input information. After a bibliographic record is created in this editor, the record is stored into an XML document that represents the editor output information. This XML document can be stored into various software systems for data storage and retrieval.

Abstract

Purpose

The aim of this research is to model and implement a software system for library circulation, so that all requirements of city and special libraries for electronic business with the library users can be fulfilled.

Design/methodology/approach

Object‐oriented methodology is used for modelling of information systems. Modelling is carried out in the CASE tool that supports the Unified Modelling Language (UML 2.0). The software architecture of the system is based on the software components and web services.

Findings

The result is a software system for library circulation. The application of the system supports the work with the local database (intranet), as well as with the remote database (internet). Also the application supports the work with different library formats (UNIMARC, MARC21 et al.).

Research limitations/implications

The system is integrated into the BISIS system so that communication with the system for cataloguing is carried out via the text server of the BISIS system. For this reason integration into the other library software systems requires an additional programming. This limitation can be solved through implementation of the software package for communication with the system for cataloguing. In this case, the integration into another library system should require only the implementation of the method of the corresponding interface for work with bibliographic records.

Originality/value

The contribution of the paper is in the system architecture that can be configured for work in the local intranet, as well as on the internet, and that is independent of the library record format. Also, the architecture enables integration of the application in different library systems.

Abstract

Purpose

The purpose of this paper is to empirically examine supervisor-subordinate relationships and their impact on performance appraisal in Croatia. Specifically, we were interested in examining how supervisor-subordinate relationships impact subordinate perceptions of performance evaluation and the subordinate's reactions to the performance evaluation.

Design/methodology/approach

This paper uses matched data from a sample of supervisors and subordinates (n = 53) in a leading organization in the hospitality industry in Croatia, as well as objective performance appraisal data to examine the impact of supervisor-subordinate relationships on subordinate reactions to performance appraisal.

Findings

The key findings of this study include (1) supervisor trustworthiness determines the quality of their relationship with subordinates and leads to interpersonal liking, and (2) supervisor-subordinate relationship quality has a significant impact on subordinate reactions to performance appraisal process and outcomes.

Research limitations/implications

The overall sample size (n = 53) of this study is small, and limits our ability to make generalizations beyond a point. Also, since the sample included only Croatian individuals, the findings maybe an artifact of the fact that they all hold similar values. Future studies should examine these relationships in supervisor-subordinate dyads comprised of individuals of different cultural backgrounds.

Practical implications

Supervisors should attempt to have high quality relationships with most, if not all, subordinates, as this would lead to higher acceptance of the performance appraisal process, which can impact future performance. Also, trustworthiness is closely related to the subordinate's perception of the quality of relationship he/she shares with the supervisor.

Originality/value

This is the first known paper to empirically study performance appraisal processes and relationships in Croatia, which also included both supervisor and subordinate perspectives.

Abstract

Purpose

This study aims to find the symmetries and conservation laws of a new Painlevé integrable Broer-Kaup (BK) system with variable coefficients. This system is an extension of dispersive long wave equations. As the system is generalized and new, it is essential to explore some of its possible aspects such as conservation laws, symmetries, Painleve integrability, etc.

Design/methodology/approach

This paper opted for an exploratory study of a new Painleve integrable BK system with variable coefficients. Some analytic solutions are obtained by Lie classical method. Then the conservation laws are derived by multiplier method.

Findings

This paper presents a complete set of point symmetries without any restrictions on choices of coefficients, which subsequently yield analytic solutions of the series and solitary waves. Next, the authors derive every admitted non-trivial conservation law that emerges from multipliers.

Research limitations/implications

The authors have found that the considered system is likely to be integrable. So some other aspects such as Lax pair integrability, solitonic behavior and Backlund transformation can be analyzed to check the complete integrability further.

Practical implications

The authors develop a time-dependent Painleve integrable long water wave system. The model represents more specific data than the constant system. The authors presented analytic solutions and conservation laws.

Originality/value

The new time-dependent Painleve integrable long water wave system features some interesting results on symmetries and conservation laws.
