Purpose: This study aims to introduce an empirical model which incorporates newsgroups, knowledge forums, knowledge assets and knowledge application processes to share organisational knowledge. Therefore it seeks to illustrate an application for integrating knowledge management (KM) into the business process. Design/methodology/approach: The Taiwanese contingent of an international certification body - also a council member of the International Organisation for Standardisation (ISO) - was selected for a case study. A hybrid technology infrastructure was designed and employed to implement the proposed model. Based on knowledge value added validation, the proposed KM model provides a set of new operating systems for sharing knowledge within an organisation. Findings: Although many theories regarding implementation of KM in organisations have been proposed and studied, an application model for practical integration of various modern principles to share organisational knowledge is strategically important. Therefore a model that integrates principal KM applications into the business process, and the measurement of the resulting benefits, has been developed. Originality/value: Knowledge is a valuable asset for an individual in today's economy; nevertheless the acquisition of such an asset relies heavily on knowledge sharing within an organisation. The author has proposed an exclusive hybrid platform with an empirical process model to address innovative approaches and practical values of KM within an organisation. © Emerald Group Publishing Limited 1468-4527.

Web forums become the means of online communication and information sharing sources for the learning about health care and related treatment knowledge. By adopting web crawlers and natural language processing techniques, the automatic identification approach of the concerned HIV-related messages is proposed to facilitate the health authorities and social support groups in instant counseling. The proposed supervised GA/k-means for classification approach can help construct an effective identification and classification model with acceptable classification performance accompanied with its full flexibility to develop different fitness functions in accordance with the need of different requirements. Furthermore, with the aid of correspondence analysis, the most frequently used terms in concerned HIV-related messages are identified and focus on risky sexual behavior whereas unconcerned messages are those who of worried well. © 2013 Taylor & Francis.

Social network awareness (SNA) has been used extensively as one of the strategies to increase knowledge sharing and collaboration opportunities. However, most SNA studies either focus on being aware of peer's knowledge context or on social context. This work proposes online formative assessments with SNA, trying to address the problems of online formative assessment (i.e. lack of individual assistances and low participant rate) and enhance learning effectiveness. This study focuses on being aware both peer's social context and knowledge context for student to promote the opportunity of peer interaction and to select the appropriate helpers to ask for help when facing problems in online assessments. Social-context information particularly includes centrality (i.e. social network position) of a candidate, and social distance (i.e. the shortest distance between the candidate and a seeker) in a sociogram, and nimbus (i.e. willingness to help others) of a candidate. A corresponding system, called Social Network Awareness for Formative Assessments (SNAFA), is further developed. The education experiments particularly focused on the effects of social-context awareness on learning activity and social activity. The results showed that the SNAFA not only increase the participant rate of students on formative assessment and opportunities of knowledge sharing, but also promote learning achievement, compared to the Traditional Formative Assessment (TFA). Meanwhile, centrality, which is represented by two indices: degree and closeness, also plays an important role in the SNAFA environment. More specifically, students with higher centrality (regardless of degree and closeness) 1) are more likely to take advantage of the social network position to ask for help, 2) easily become target helpers that peers seek to, 3) utilize the SNAFA more frequently, and 4) have better learning achievement, compared with those with lower centrality. © 2013 Elsevier Ltd.

The development of a real-time monitoring and early warning system and corresponding decision-making procedures has become a high-priority concern for the Taiwanese government in recent years. Studies have indicated that observing water level and scour depth is not sufficient for evaluating bridge safety. Therefore, a high-tech bridge safety monitoring system based on monitoring the vibration behaviour of a bridge is developed in this study and applied to Xibin Bridge. A flood event is recorded and studied to understand the relationship between bridge vibration behaviours and scour. The study results for the monitoring system are verified using in-field vibration measurements and simulations by a numerical model.
