Abstract

Purpose

Digital humanities database is one of the essential tools in digital humanities research area. Therefore, examining the usage of digital humanities database in academic papers is conducive to assessing the value of digital humanities database for scientific research activities and improving the construction of digital humanities infrastructure.

Design/methodology/approach

This paper constructs an evaluation system of digital humanities database from the perspective of academic influence and social influence, with mention frequency, usage motivation, platform access data, usage region and usage discipline as indicators and takes China Biographical Database Project as the empirical object to explore the usage of digital humanities database in China.

Findings

The data analysis result demonstrates that digital humanities databases are widely used and recognized in China. However, the problem of low actual usage remains.

Originality/value

This paper constructs the digital humanistic database's evaluation system and discusses applying the digital humanistic database in China, which provides a new perspective and method for the influence evaluation study of the digital humanistic database.

Abstract

Purpose

Graph rewriting concerns the technique of transforming a graph; it is thus natural to conceive its application in the evolution of graph databases. This paper aims to propose a two-step framework where rewriting rules formalize instance or schema changes, ensuring graph’s consistency with respect to constraints, and updates are managed by ensuring rule applicability through the generation of side effects: new updates which guarantee that rule application conditions hold.

Design/methodology/approach

This paper proposes Schema Evolution Through UPdates, optimized version (SetUpOPT), a theoretical and applied framework for the management of resource description framework (RDF)/S database evolution on the basis of graph rewriting rules. The framework is an improvement of SetUp which avoids the computation of superfluous side effects and proposes, via SetUpoptND, a flexible and extensible package of solutions to deal with non-determinism.

Findings

This paper shows graph rewriting into a practical and useful application which ensures consistent evolution of RDF databases. It introduces an optimised approach for dealing with side effects and a flexible and customizable way of dealing with non-determinism. Experimental evaluation of SetUpoptND demonstrates the importance of the proposed optimisations as they significantly reduce side-effect generation and limit data degradation.

Originality/value

SetUp originality lies in the use of graph rewriting techniques under the closed world assumption to set an updating system which preserves database consistency. Efficiency is ensured by avoiding the generation of superfluous side effects. Flexibility is guaranteed by offering different solutions for non-determinism and allowing the integration of customized choice functions.

Abstract

Purpose

The study aims to survey information-seeking behavior of the Iranian medical faculty members and to identify the reasons and obstacles of their usage via the internet, scientific databases and online social networks.

Design/methodology/approach

In this cross-sectional study, a structured questionnaire used to collect data. The research population includes faculty members of four faculties of Hamadan University of Medical Sciences in Iran, including health, nursing – midwifery, paramedicine and rehabilitation. SPSS software was used to analyze data in descriptive and analytical levels.

Findings

Low internet speed, network traffic and lack of time were the main barriers and difficulties. Gender was significantly related with familiarity with databases, problems and barriers to accessing information, barriers to using social network, as well as purpose and motivation of using social network. Search for educational and research resources and use of social network to increase their general information were the main goals of participants to using the internet and databases. A negative significant relationship was observed between usage of social network with age (r = −0.204, P = 0.047) and experience (r = −0.239, P = 0.019).

Originality/value

The usage of faculty members of various digital resources is growing ever more. This study examines the use of faculty members of the internet, scientific databases and online social networks simultaneously.

Abstract

As yet, the services and guides offered commercially do not address the problem of database selection fully. There is a need for a database selector that can either take database selection out of the hands of the inexperienced or act as an advisor to more experienced online users. One approach to assisting business database selection is to produce better software, but of what type? Examination of the problem suggests that an expert system, which embodies and applies problem‐solving skills, might be suitable, since the task of database selection requires specific cognitive skills; intermediaries with skills in selecting databases exist; and intermediaries can articulate the methods they use to select databases.

Abstract

The characteristics and advantages of database machines are summarized, and the application of database machines to library functions is described, noting the ability to attach multiple hosts to the same database, as well as flexibility in choosing operating and database management systems for different functions without loss of access to a common database.

Abstract

Outlines two distinct views of database marketing – as a total marketing strategy and as a tactical tool. Argues that a database marketing strategy can be realized only in companies with a genuine customer focus. As a result the tactical choice is more appropriate to most companies. Suggests that the problems of database saturation, where further cross‐selling using a database is not cost‐effective, can be overcome through widening the company′s credibility as a supplier as well as by increasing the size of the database. A database marketing strategy uses the tools of image and brand building to establish this credibility.

Abstract

To date, librarians have not produced a study comparing databases that are appropriate for political science research. This study compares the coverage, content, and retrieval methods for nine databases. The study uses sampling to evaluate search results for six topics, providing relevancy percentages for each database. The article also reviews the types of documents cited in these samples, and provides recommendations for matching each database to particular research needs.

Abstract

A framework based on the database entropy concept developed for characterizing the learning process of a database is applied to the dynamic measurement of the promptness and coherence of a distributed database. The results can be of great value in the design and implementation of self‐adaptive distributed databases.

Abstract

The value of downloading for database users is identified. These values are for temporary storage of data to repackage information and long term storage in newly created internal databases. The impact of these activities on the database producers and online vendors is discussed. Two factors which affect the volume of downloading are the availability of the technology and the legal implications of downloading. Several pricing policy solutions are mentioned.
