Abstract

Purpose

This paper aims to present social trust as a variable of influence by demonstrating the possibilities of trusted social nodes to improve influential capability and rate of successfully influenced social nodes within a social networking environment.

Design/methodology/approach

This research will be conducted using simulated experiments. The base algorithm in research uses genetics algorithm diffusion model (GADM) where it carries out social influence calculations within a social networking environment. The GADM algorithm will be enhanced by integrating trust values into its influential calculations. The experiment simulates a virtual social network based on a social networking site architecture from the data set used to conduct experiments on the enhanced GADM and observe their influence capabilities.

Findings

The presence of social trust can effectively increase the rate of successfully influenced social nodes by factorizing trust value of one source node and acceptance rate of another recipient node into its probabilistic equation, hence increasing the final acceptance probability.

Research limitations/implications

This research focused exclusively on conceptual mathematical models and technical aspects so far; comprehensive user study, extensive performance and scalability testing is left for future work.

Originality/value

Two key contributions of this paper are the calculation of social trust via content integrity and the application of social trust in social influential diffusion algorithms. Two models will be designed, implemented and evaluated on the application of social trust via trusted social nodes and domain-specified (of specific interest groups) trusted social nodes.

Abstract

Purpose

The purpose of this study is to investigate the perception of knowledge workers on practice of knowledge management (POKM) as an organizational knowledge sharing enabler in an information technology shared services company to understand issues faced and provide recommendations on different technological characteristics of the system.

Design/methodology/approach

The initial stage of the research involved a preliminary review of the existing knowledge management-related documents. This was followed by a top management interview to understand the organization’s business goals and knowledge management (KM) expectations. A total of 70 knowledge workers took part in the research activity. Twenty-five participants from nine departments took part in the preliminary interview, and 52 successful survey forms were collected from a total of 70 respondents. The entire investigation took close to nine months. Data compilation and research result analysis took about three months to complete.

Findings

The outcomes of the research show that the quality of POKM is stable, easy to use and organization of the content is rated as good. However, POKM has poor response time and search capability. The content is found to be difficult to locate in the POKM but most participants agree that knowledge stored in the POKM is helpful, can be accessed anytime and anywhere and useful for their day-to-day job. As for the user interface, POKM is not very pleasant to use with a weak set of functions and features. For user satisfaction toward POKM, it is shown that users are not satisfied with the efficiency and effectiveness of the systems. However, employees generally are satisfied with the ease of access, download and reuse of knowledge contains in POKM. In term of perceived POKM benefits, users agree that POKM is an enabler for acquiring new knowledge and innovative ideas, managing and storing knowledge and accomplishing tasks more efficiently. Lastly, knowledge users agree that POKM functions enable knowledge networking, sharing and creation in the organization.

Originality/value

POKM was launched and implemented for close to 10 years; however, the organization has failed to achieve some of the goals such as knowledge sharing among employees, creation of new skills and knowledge, measuring knowledge sharing activities and knowledge sharing strategy. The importance of this study is to understand and highlight the technological perspective of POKM from the knowledge workers. Findings will summarize issues faced by the case company for further action and remedy. The outcomes of the study also provide a comprehensive view and guideline to organizations who are interested to implement a KM system.
