Abstract

Purpose

Dissertations from the University of Novi Sad (UNS) are integrated with the research information system called the current research information system (CRIS) UNS. This paper aims to present a proposal for an extension of this system to enable the storage of student papers as prescribed by PhD study exam obligations. The proposed extension enables preservation and improves discoverability of scientific and technical works produced by students during their PhD studies.

Design/methodology/approach

An analysis of examination modes in accredited PhD study programs has been conducted. It was noted that students in examination modes verify the obtained results in the form of scientific and technical work. The main idea of this paper is to enable the preservation of those student results and to implement electronic services for retrieving those results by current and future PhD students to empower the development of science.

Findings

The proposal includes an extension of the CRIS UNS to store and publish student papers as prescribed as a PhD study exam obligation; an extension of the CERIF data model to enable storing of student papers; cataloguing student papers in the MARC 21 format; and a way to represent student papers in the Dublin Core format.

Practical implications

This paper can be a starting point for initiatives for the creation of institutional, regional, national and international Web portals for searching and browsing papers by PhD students.

Social implications

This system offers the improvement of cooperation between PhD students from different institutions and countries.

Originality/value

The paper presents an extension of institutional, national and international current research information system (CRIS) systems which will enable the preservation and improve discoverability of student papers produced during PhD studies. The proposed extension has been verified by its implementation within the CRIS UNS system, which also supports monitoring of the scientific competencies of students based on an automatic evaluation of published scientific results.

Abstract

Purpose

The purpose of this article is to describe a proposition for the evaluation of citations of scientific papers, which could serve as a supplement to the existing Rule Book of the Ministry of the Republic of Serbia, which is used in the procedure of electing candidates for particular academic and research titles. The evaluation and quantitative presentation of the results and evaluation of citations were carried out on data taken from the database of the Current Research Information System of the University of Novi Sad (CRIS UNS), which is harmonized with the Rule Book of the Ministry with respect to the evaluation of published scientific results of researchers.

Design/methodology/approach

There are different criteria to evaluate the quality of scientific papers based on their citations. The pertinent parameters can be the total number of citations, the number of citations in a defined time period and by assigning the appropriate weighting values to the citations. This work proposes a procedure of assigning the citation weighting values based on the evaluation of the scientific results in which the citation appeared according to the Rule Book in the Republic of Serbia. Based on this, the authors introduced the impact factor of researchers as the ratio of the number of points of the evaluated citations and the number of points of the evaluated papers of the researcher.

Findings

Results showed that the research information system CRIS UNS can be extended to the evaluation of citations for a single researcher, groups of researchers and institutions.

Practical implications

The proposed solution enables the evaluation of citations in the process of election and promotion of academic staff. In this way, there is a means for measuring the scientific influence of a researcher in the relevant scientific area.

Social implications

The evaluation of citations may be included in the national strategies of scientific development, funding and evaluation of research projects; for promotions of academic staff at the universities and other academic institutions; and ranking of researchers and research organizations.

Originality/value

The main idea presented in the paper is the definition of a rule book (or several rule books) for the evaluation of citations. Based on the evaluation of citations, the authors proposed the term “the impact factor of researcher”.

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 goal of this paper is to propose a data access control framework that is used for editing MARC‐based bibliographic databases. In cases where the bibliographic record editing activities carried out in libraries are complex and involve many people with different skills and expertise, a way of managing the workflow and data quality is needed. Enforcing access control can contribute to these goals.

Design/methodology/approach

The proposed solution for data access control enforcement is based on the well‐studied standard role‐based access control (RBAC) model. The bibliographic data, for the purpose of this system, is represented using the XML language. The software architecture of the access control system is modelled using the Unified Modelling Language (UML).

Findings

The access control framework presented in this paper represents a successful application of concepts of role‐based access control to bibliographic databases. The use of XML language for bibliographic data representation provides the means to integrate this solution into many different library information systems, facilitates data exchange and simplifies the software implementation because of the abundance of available XML tools. The solution presented is not dependent on any particular XML schema for bibliographic records and may be used in different library environments. Its flexibility stems from the fact that access control rules can be defined at different levels of granularity and for different XML schemas.

Research limitations/implications

This access control framework is designed to handle XML documents. Library systems that utilise bibliographic databases in other formats not easily convertible to XML would hardly integrate the framework into their environment.

Practical implications

The use of an access control enforcement framework in a bibliographic database can significantly improve the quality of data in organisations where record editing is performed by a large number of people with different skills. The examples of access control enforcement presented in this paper are extracted from the actual workflow for editing bibliographic records in the Belgrade City Library, the largest public city library in Serbia. The software implementation of the proposed framework and its integration in the BISIS library information system prove the practical usability of the framework. BISIS is currently deployed in over 40 university, public, and specialized libraries in Serbia.

Originality/value

A proposal for enforcing access control in bibliographic databases is given, and a software implementation and its integration in a library information system are presented. The proposed framework can be used in library information systems that use MARC‐based cataloguing.

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 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

The purpose of this research is to observe all data from the Common European Research Information Format (CERIF) data model that can be described using bibliographic standards and move those data to a data model of bibliographic standard.

Design/methodology/approach

Analysis of the CERIF data model and the MARC 21 format has shown that some elements of the CERIF data model could be mapped to the MARC 21 bibliographic record. A CERIF compatible data model based on the MARC 21 format is proposed. The data model was created using PowerDesigner CASE tool. The proposed data model is represented using a physical data model in the conceptual notation that is adopted in the literature for representing the CERIF data model.

Findings

A CERIF compatible data model based on the MARC 21 format is proposed. The proposed model contains all the data from the CERIF2008 data model. The central part of the proposed model is MARC 21 data model that is used as a replacement for 27 entities of the CERIF data model, including all their attributes as well as part of the attributes in entities related to organisational unit. The mappings between attributes of entities of the CERIF data model and the data model of the MARC 21 format are described.

Research limitations/implications

The CERIF compatible data model based on the MARC 21 format does not support all restrictions on data types, which are defined by the CERIF data model. This means that such restrictions have to be controlled by software.

Practical implications

The central part of the proposed CERIF compatible data model is a data model of MARC 21 format. It means that most of the data are modelled according to bibliographic standard, which is very widespread worldwide. This implies that the proposed CERIF model can be easily implemented within the existing library infrastructure. In addition, the proposed model can be used for other purposes, such as the evaluation of scientific research results, generating bibliographies of researchers, and institutions, the citations etc. A research management system based on the proposed model is implemented. Also, this system is verified and tested on data about published results of researchers employed at University of Novi Sad, Serbia.

Originality/value

A new data model compatible with the CERIF data model is proposed. The basic idea is to map part of the CERIF data model related to published results of scientific research to some well‐known bibliographic standard. It was shown that this part of the data model could be mapped to the MARC 21 data model. It can be mapped to data models of any other MARC standards in a similar way.

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 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

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.
