Client-side mobile user profile for content management using data mining techniques
Mobile device can be used as a medium to send and receive the mobile internet content. However, there are several limitations using mobile internet. Content personalisation has been viewed as an important area when using mobile internet. In order for personalisation to be successful, understanding the user is important. In this paper, we explore the implementation of the user profile at client-side, which may be used whenever user connect to the mobile content provider. The client-side user profile can help to free the provider in performing analysis by using data mining technique at the mobile device. This research investigates the conceptual idea of using clustering and classification of user profile at the client-site mobile. In this paper, we applied K-means and compared several other classification algorithms like TwoStep, Kohenen and Anomaly to determine the boundaries of the important factors using information ranking separation
Architectural building safety and health performance model for stratified low-cost housing: education and management tool for building managers
The safety and health performances aspects of a building are the most challenging aspect of facility management. It requires a deep understanding by the building managers on the factors that contribute to health and safety performances. This study attempted to develop an explanatory architectural safety performance model for stratified low-cost housing in Malaysia. The proposed Building Safety and Health Performance (BSHP) model was tested empirically through a survey on 308 construction practitioners using partial least squares (PLS) and structural equation modelling (SEM) tool. Statistical analysis results supports the conclusion that architecture, building services, external environment, management approaches and maintenance management have positive influence on safety and health performance of stratified low-cost housing in Malaysia. The findings provide valuable insights for construction industry to introduce BSHP model in the future where the model could be used as a guideline for training purposes of managers and better planning and implementation of building management
Pervasive business intelligence platform to improve the quality of decision process in primary and secondary education – A Portuguese case study
Business Intelligence (BI) can be seen as a method that gathers
information and data from information systems in order to help companies to be
more accurate in their decision-making process. Traditionally BI systems were
associated with the use of Data Warehouses (DW). The prime purpose of DW is to
serve as a repository that stores all the relevant information required for making the
correct decision. The necessity to integrate streaming data became crucial with the
need to improve the efficiency and effectiveness of the decision process. In primary
and secondary education, there is a lack of BI solutions. Due to the schools reality
the main purpose of this study is to provide a Pervasive BI solution able to
monitoring the schools and student data anywhere and anytime in real-time as well
as disseminating the information through ubiquitous devices. The first task
consisted in gathering data regarding the different choices made by the student since
his enrolment in a certain school year until the end of it. Thereafter a dimensional
model was developed in order to be possible building a BI platform. This paper
presents the dimensional model, a set of pre-defined indicators, the Pervasive
Business Intelligence characteristics and the prototype designed. The main
contribution of this study was to offer to the schools a tool that could help them to
make accurate decisions in real-time. Data dissemination was achieved through a
localized application that can be accessed anywhere and anytime.This work has been supported by FCT - Fundação para a Ciência e Tecnologia within the Project Scope UID/CEC/00319/2013
Considerations regarding the agile development of portals
Starting with methodologies, methods and techniques used generally in the development of information systems, a personal approach regarding quick development of portals has been introduced. After a strict theoretical foundation the proposal has been applied within a real collaborative knowledge portal development project. We consider the proposed agile development approach (based on the prototype technique enriched with MDA valences) suitable to all kind of information systems. The agile development framework establishes the life-cycle phases of product development taking into account the desired functionalities.portal, prototype technique, model driven architecture, agile development
