Analysis of intra-institutional research collaboration: a case of a Serbian faculty of sciences

Current research information systems (CRISs) offer great opportunities for scientometric studies of institutional research outputs. However, many of these opportunities have not been explored in depth, especially for the analysis of intra-institutional research collaboration. In this paper, we propose a hybrid methodology to analyze research collaboration networks with an underlying institutional structure. The co-authorship network extracted from the institutional CRIS of the Faculty of Sciences, University of Novi Sad, Serbia, is analyzed using the proposed methodology. The obtained results show that the organizational structure of the institution has a profound impact on both inter- and intra-institutional research collaboration. Moreover, researchers involved in inter-department collaborations tend to be drastically more productive (by all considered productivity measures), collaborative (measured by the number of co-authorship relations) and institutionally important (in terms of the betweenness centrality in the co-authorship network) compared to those who collaborate only with colleagues from their own research departments. Finally, our results indicate that quantifying research productivity by the normal counting scheme and Serbian research competency index is biased towards researchers from physics and chemistry research departments.

A BIBO ontology extension for evaluation of scientific research results

The paper addresses the issue of semantic description of the bibliographic data in RDF and OWL. More precisely, the paper focuses on presenting scientific research results together with their evaluation and quantitative expression. The existing ontologies that are commonly used for describing bibliographic data are Dublin Core, FOAF and BIBO. The paper gives a proposal for presenting data for evaluation of scientific results as an extension of the BIBO ontology. The purpose of the research in this paper is going towards research management system integration in terms of evaluation of scientific research results for individuals and institutions.

Developing an Eclipse editor for MARC records using Xtext

In this paper, we present the idea of developing an editor for MAchine‐Readable Cataloguing records that is part of a library management system. The idea was realized and implemented as a part of the library management system BISIS. The objective was to generate an Eclipse plug‐in of the editor in an Xtext environment by specifying the Xtext grammar and generating an Eclipse Modelling Framework model of the MAchine‐Readable Cataloguing record. The next step was to specify additional features of the editor in the Xtext environment such as content assist and constraints on the record used for checking the correctnessu2009of the input. The implementation of additional functionalities of the editor was carried out in the Eclipse plug‐in development environment, and user interface components were implemented by using Standard Widget Toolkit and JFace libraries. A special emphasis is placed on the Eclipse extension model that relies on the Open Services Gateway initiative standard and enables efficient implementation of the systems with a component‐based, service‐oriented architecture. We took advantage of that model and created an extensible and adoptable application that can be used by any database management system and can be integrated in other library management systems. Finally, we discuss a possible way of extracting applications from Eclipse by using Rich Client Platform technology. Copyright

Towards Culture-Sensitive Extensions of CRISs: Gender-Based Researcher Evaluation

Current research information systems (CRISs) offer great opportunities for extraction of useful and actionable knowledge based on various data analysis techniques. However, many of these opportunities have not been explored in depth, especially in culture-sensitive areas such as gender-based evaluation of researchers. In this paper, we present GERBER, a methodology and accompanying tool for performing gender-based analysis of CRIS data. The tool enables the extraction of co-authorship networks, computation of various author metrics, and statistical comparison of male and female researchers. Functionality of GERBER is demonstrated on data extracted from the CRIS of the University of Novi Sad (UNS). We also present a plan to integrate GERBER into CRIS UNS in order to facilitate continuous gender-based researcher evaluation. Experiences obtained during such integration will enable us to propose more general methodological guidelines and APIs for culture-sensitive extensions of CRIS systems and standards.

A community detection technique for research collaboration networks based on frequent collaborators cores

Community structure is one of prominent features of complex real-world networks. In this paper we propose a novel technique for detecting communities in research collaboration networks. The main idea of the algorithm is that research communities can be efficiently recovered from sub-graphs encompassing frequent collaborators. Moreover, the algorithm can be used to cluster weighted undirected networks from other domains as well. An experimental evaluation of the algorithm was conducted on a co-authorship network representing collaborations between researchers employed at our Department. The results of the evaluation showed that the algorithm identifies strong and meaningful clusters corresponding to groups dealing with specific research topics. Moreover, we compared our method to seven other community detection techniques showing that it performs better or equally with respect to the quality of obtained community structures.

USING OCL IN THE FORMAL SPECIFICATION OF THE LIBRARY STANDARDS

The goal of the research was to check whether we can use a formal specification language such as OCL — Object Constraint Language to express all constraints on the library records proposed by the M...

Evaluation of citations: a proposition to supplement the corresponding rule book in Serbia

Purpose n n n n nThe 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. n n n n nDesign/methodology/approach n n n n nThere 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. n n n n nFindings n n n n nResults 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. n n n n nPractical implications n n n n nThe 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. n n n n nSocial implications n n n n nThe 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. n n n n nOriginality/value n n n n nThe 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”.

Cataloguing government documents using the MARC 21: A case study of materials from the AP Vojvodina government sessions

The paper provides suggestions for cataloguing session materials (especially minutes of sessions) using the MARC 21 Format for Bibliographic Data and MARC 21 Format for Authority Data. The suggested solution is shown on the example of materials from the government of the Autonomous Province of Vojvodina in Serbia (APV) sessions. Two business applications were developed on the basis of this MARC 21 cataloguing of the materials: a web application for searching government materials and a web application for generating various reports for the APV government. The web application supports searching metadata as well as the full text of the material and search criteria may include all of the given words or exact phrase. The examples of the reports supported by the application are: total number of sessions; total number of agenda items and sub-items; session attendance by the government members.
