In the past few years, a new wave of many technologies, particularly the Internet has emerged with the potential to further enhance the teaching and learning environment in higher education. Many studies in the recent years have shown that E-learning use in the classrooms has increased over the past years. However, the process of E-learning and its applications is limited in the Kingdom of Saudi Arabia. Through this empirical study, a limited research was initiated to track the perceptions of the students toward the E-learning. The results indicate an overall positive attitude towards the E-learning. Read More Read Less

Abstract This paper encompasses the factors affecting the localisation and internationalisation of web sites, more specifically, a virtual restaurant booking web site. A subset of the key web usability issues derived was used in the experimental design and was known as web site variables. These variables were classified into Text Elements construct, Web Interface Elements construct and Web Design Elements construct.... This paper encompasses the factors affecting the localisation and internationalisation of web sites, more specifically, a virtual restaurant booking web site. A subset of the key web usability issues derived was used in the experimental design and was known as web site variables. These variables were classified into Text Elements construct, Web Interface Elements construct and Web Design Elements construct. This paper reports on the usability aspects of HCI, localisation and internationalisation of web sites, and the initial results of a main study phase. Read More Read Less

Abstract Among the techniques that the distributed database designer considers for performance improvement are fragmentation, replication and allocation techniques. Fragmentation is the process of dividing a relation into two or more relations called fragments. Usually two fragmentation techniques are considered, these are: vertical and horizontal fragmentation. A third rarely considered one is hybrid or mixed fragmentation. In this paper, vertical fragmentation... Among the techniques that the distributed database designer considers for performance improvement are fragmentation, replication and allocation techniques. Fragmentation is the process of dividing a relation into two or more relations called fragments. Usually two fragmentation techniques are considered, these are: vertical and horizontal fragmentation. A third rarely considered one is hybrid or mixed fragmentation. In this paper, vertical fragmentation along with a two-phases allocation method in the context of relational DDBSs is proposed to partition a relation vertically and allocate the resulting fragments/attributes across different sites. The proposed algorithm will greatly minimize communication cost and query response time in DDBSs. Empirical results have supported this hypothesis and shown that this method will present an efficient solution to vertical fragmentation and allocation problem in distributed environments.

Abstract In the context of the National Agency of Research project “Miipa-doc”, we develop a new type of Knowledge Organization System (KOS) called Hypertagging based on the tagging of electronic documents and the principles of faceted classification.

In the context of the National Agency of Research project “Miipa-doc”, we develop a new type of Knowledge Organization System (KOS) called Hypertagging based on the tagging of electronic documents and the principles of faceted classification. It was designed to simplify the tasks of information management for the organizations’ staff. In this paper, we propose a new recommendation model and algorithm which are based on a faceted classification by level in the aim to facilitate the documents’ indexing. This approach exploits the user trace indexing of his/her documents to learn about the user preferences and then to produce their recommendations. Consequently, these recommendations will provide a kind of knowledge base aiming at improving document ranking and highlight most relevant information that meeting user needs. This model is based on a statistical method called Association Rules (AR) using an Apriori algorithm to generate the recommendations. Read More Read Less

Abstract In the current era of knowledge economy scientific productivity measurement has profound implications. Scientific collaboration is a core component in scientific collaboration measurement for which researches use a few determinants. We in this study have measured the scientific collaboration in Canadian Universities during the period 2002 and 2008 using Canadian Bibliometric Database (CBD) of the Observatory of Science and Technology... In the current era of knowledge economy scientific productivity measurement has profound implications. Scientific collaboration is a core component in scientific collaboration measurement for which researches use a few determinants. We in this study have measured the scientific collaboration in Canadian Universities during the period 2002 and 2008 using Canadian Bibliometric Database (CBD) of the Observatory of Science and Technology (OST-Quebec). Using an exploratory model, we did analyses of the data and found that the funding has significant impact on the quality of publications. Our results also reveal that organizational attributes play a crucial role in explaining research collaboration, especially in terms of the language of universities. Read More Read Less
