Discovering the Impact of Knowledge in Recommender Systems: A Comparative Study

Recommender systems engage user profiles and appropriate filtering techniques to assist users in finding more relevant information over the large volume of information. User profiles play an important role in the success of recommendation process since they model and represent the actual user needs. However, a comprehensive literature review of recommender systems has demonstrated no concrete study on the role and impact of knowledge in user profiling and filtering approache. In this paper, we review the most prominent recommender systems in the literature and examine the impression of knowledge extracted from different sources. We then come up with this finding that semantic information from the user context has substantial impact on the performance of knowledge based recommender systems. Finally, some new clues for improvement the knowledge-based profiles have been proposed.Comment: 14 pages, 3 tables; International Journal of Computer Science & Engineering Survey (IJCSES) Vol.2, No.3, August 201

Penyelesaian masalah persamaan resapan olakan satu dimensi secara selari dan berjujukan

This article discusses the solution of one-dimensional convection-diffusion equations by using Successive Over-Relaxation Red Black (SORRB) and Gauss-Seidel Red Black (GSRB) method for parallel and sequential. The implementation for this method has been performed on parallel computers for distributed memory systems using Parallel Virtual Machine (PVM) and C which used 18 personal computers with Intel Pentium IV processor. This research successfully results in affirmation of the theories presented by Foster (1995) which proposed that the percentage of efficiency decreases and the speedup factor increases when the numbers of processors are increasing. The research result also shows that the parallelization of GSRB and SORRB method is faster than sequential especially when the number ofprocessors increased. As a conclusion, problem solving by using parallelization will reduce execution time especially in solving large scale problems

STRATEGIC COMMUNICATION THROUGH DIGITAL PUBLIC RELATIONS AND ITS TREND IN MALAYSIA

The development of strategic communication practices through the use of digital platforms is seen to have an impact on the sustainability of strategic communication in the public and private sectors. Strategic communication is a process that determines the stability of an organization’s image, reputation, and position. The digital platform now not only serves as the main communication medium, but also able to function as a platform for dialogue communication between content creators and followers of the platform. Accordingly, the theory used to explain this article is the strategic communication theory (Hallahan et.al, 2007) According to Hallahan, strategic communication is involved in the development, implementation, and assessment of communication. This research aims to understand the impact and the role of strategic communication through digital public relations and its trends in Malaysia. The discussion and fndings in this research are based on a qualitative study that uses an in-depth interview method as a data collection technique and 12 informants among communication practitioners in Malaysia were selected through a purposive sampling technique. The results of the study found that strategic communication through digital public relations is used continuously and has a very important role to ensure that all communication strategies are used to reach the target audience. However, the function and impact of using digital platforms as the main medium of strategic communication still cannot guarantee the sustainability of corporate communication in the future

Social media and agenda setting: implications on political agenda

Since the advent of the Internet, political information is now at the fingertips of every Malaysian, especially those living in the urban areas and having access to the Internet. One does not need to have the traditional media such as radio, television or Newspaper to understand what is happening in political set up in Malaysia these days. This is because the social media, especially Facebook and twitter have made access to information so easy to the larger population. The aim of this paper is to explore the role of social media as agenda setting mechanisms in the Malaysia political scenario. The study uses secondary data sources to obtain insight on the issue. It is evident from literature that the social media, especially the social media (eg. Facebook) play an important role in shaping public opinion on important political matters. The social media has been used by the public to express their concern and grievance on issues that concern their welfare which the traditional media may not dare to report or broadcast. Agenda setting needs to be relooked into as the public agenda is taking a central stage through the new/social media. Thus, it implies, the agenda setting model could be extended or remodeled to include the new/social media due to their influence on public agenda. Further implication of this is that politicians should keep abreast with the development in the social media so that they will understand current issues that are of great concern to the people and the society at large. We have to come to terms with the fact that we are now in the digital and globalised era, hence agenda setting needs to be relooked into as the public agenda is taking a central stage through the social media
