Public Cloud Data Auditing With Practical Key Update And Zero Knowledge Privacy, Yong Yu, Yannan Li, Man Ho Au, Willy Susilo, Kim-Kwang Raymond Choo, Xinpeng Zhang
Faculty of Engineering and Information Sciences - Papers: Part A
Data integrity is extremely important for cloud based storage services, where cloud users no longer have physical possession of their outsourced files. A number of data auditing mechanisms have been proposed to solve this problem. However, how to update a cloud user's private auditing key (as well as the authenticators those keys are associated with) without the user's re-possession of the data remains an open problem. In this paper, we propose a key-updating and authenticator-evolving mechanism with zero-knowledge privacy of the stored files for secure cloud data auditing, which incorporates zero knowledge proof systems, proxy re-signatures and homomorphic linear authenticators. …

Disaster Management (DM) is a complex set of interrelated activities. The activities are often knowledge intensive and time sensitive. Sharing the required knowledge timely is critical for DM. In developed countries, for recurring disasters (e.g. floods), there are dedicated document repositories of Disaster Management Plans (DMP) that can be accessed as needs arise. However, accessing the appropriate plan in a timely manner and sharing activities between plans often requires domain knowledge and intimate knowledge of the plans in the first place. In this paper, we introduce an agent-based knowledge analysis method to convert DMPs into a collection of knowledge units …

Tibetan Word Sense Disambiguation Based On A Semantic Knowledge Network Diagram, Lirong Qiu, Xinmin Jiang, Renqiang Ling
Faculty of Engineering and Information Sciences - Papers: Part A
The method based on semantic knowledge is the most dynamic research direction in rule-based techniques. This method has been proven effective in studying English and Chinese word sense disambiguation. This study proposes two methods for selecting the correct Chinese meaning of Tibetan ambiguous words from Tibetan sentences in Tibetan-Chinese parallel corpora using semantic knowledge from HowNet and translation information from the aforementioned corpora. We can use these methods to build Tibetan-Chinese parallel corpora with word sense tagging. The two proposed methods are 1) the word sense disambiguation method based on HowNet and Tibetan-Chinese parallel corpora, and; 2) the semantic knowledge-based …
Inter-Organisational Knowledge Sharing In Regional Sustainable Development Communities, Rosemary Van Der Meer, Luba Torlina, Jamie Mustard
Inter-Organisational Knowledge Sharing In Regional Sustainable Development Communities, Rosemary Van Der Meer, Luba Torlina, Jamie Mustard
Faculty of Engineering and Information Sciences - Papers: Part A
There has been an increasing interest in the use of inter-organisational groups to address regional implications in sustainable development. These groups bring together local knowledge and expertise and span boundaries between government and industry organisations. Our focus is in understanding how knowledge is shared in such inter-organisational groups. Utilising interviews, observations and social network analysis, we examine the knowledge sharing implications derived from the mixed membership, multilevel interaction, and the need to span boundaries with external organisations in these collaborations.

The purpose of this paper is to examine the resource influences on the knowledge sharing in teleconsultation. The study was conducted by interviewing 28 participants from 11 hospitals in the Ministry of Health, Malaysia. Top-down microanalysis of interview data was performed using a descriptive knowledge sharing framework that focuses on resource influences. The results indicate that resources can influence knowledge sharing opportunities in teleconsultation in areas such as professional development and learning, greater training opportunities, having champions within the hospitals, IT support and the facilitation from administration.
A Framework For Inter-Organizational Knowledge Sharing: Managerial Influences, Rosemary A. Van Der Meer, Luba Torlina
A Framework For Inter-Organizational Knowledge Sharing: Managerial Influences, Rosemary A. Van Der Meer, Luba Torlina
Faculty of Engineering and Information Sciences - Papers: Part A
The purpose of this paper is to determine whether an existing organizational knowledge management framework could be utilized in an inter-organizational domain. We selected the threefold KM framework developed by Holsapple and Joshi (2000; 2002). This framework has been well tested and provides clearly defined elements to examine the influences on knowledge management and knowledge sharing in an organizational context. We report the results of testing the framework in three inter-organizational case studies and propose some adaptations to the managerial influences for inter-organizational analysis.
A Social Network Model For Understanding Technology Use For Knowledge-Intensive Workers, Kon Shing Kenneth Chung
A Social Network Model For Understanding Technology Use For Knowledge-Intensive Workers, Kon Shing Kenneth Chung
Faculty of Engineering and Information Sciences - Papers: Part A
This chapter presents a theoretical model based on social network theories and the social influence model for understanding how knowledge professionals utilise technology. In particular, the association between egocentric network properties (structure, position and tie) and information and communication technology (ICT) use of individuals in knowledge-intensive and geographically dispersed settings is explored. A novel triangulation methodology is adopted where in-depth interviews and observation techniques were utilised to develop constructs for the conceptual model which were then vetted by domain-level experts. A reliable and validated social network-based questionnaire survey is also developed to operationalise the model. Results show that task-level ICT …

Evaluating Disaster Management Knowledge Model By Using A Frequency-Based Selection Technique, Siti Hajar Othman, Ghassan Beydoun
Faculty of Engineering and Information Sciences - Papers: Part A
Disaster Management (DM) is a multidisciplinary endeavour and a very difficult knowledge domain to model. It is a diffused area of knowledge that is continuously evolving and informally represented. Metamodel is the output artefact of metamodelling, a software engineering approach, which makes statements about what can be expressed in the valid models of the knowledge domain. It is an appropriate high level knowledge structure to facilitate it being communicated among DM stakeholders. A Disaster Management Metamodel (DMM) is developed. To satisfy the expressiveness and the correctness of a DMM, in this paper we present a metamodel evaluation technique by using …

Knowledge Sharing Through Virtual Layers In Regional Sustainable Development Networks, Rosemary A. Van Der Meer, Luba Torlina, Jamie Mustard
Faculty of Engineering and Information Sciences - Papers: Part A
Our research examines how the organisational structure facilitates knowledge sharing within the group. This case study examines a Victorian regional sustainable group using interviews and social network analysis to identify the group's organisational structure and its effect on knowledge sharing between the members. Our findings indicate that while the mixed membership, lack of hierarchy and layered structure are complex, these elements work together to provide members with a rich body of knowledge. The diversity and differences in membership are complimentary and combined can provide a more in-depth understanding of the regional sustainable development issues.
A State-Based Knowledge Representation Approach For Information Logical Inconsistency Detection In Warning Systems, Jun Ma, Guangquan Zhang, Jie Lu
A State-Based Knowledge Representation Approach For Information Logical Inconsistency Detection In Warning Systems, Jun Ma, Guangquan Zhang, Jie Lu
Faculty of Engineering and Information Sciences - Papers: Part A
Detecting logical inconsistency in collected information is a vital function when deploying a knowledge-based warning system to monitor a specific application domain for the reason that logical inconsistency is often hidden from seemingly consistent information and may lead to unexpected results. Existing logical inconsistency detection methods usually focus on information stored in a knowledge base by using a well-defined general purpose knowledge representation approach, and therefore cannot fulfill the demands of a domain-specific situation. This paper first proposes a state-based knowledge representation approach, in which domain-specific knowledge is expressed by combinations of the relevant objects' states. Based on this approach, …
Network Structure, Ict Use And Performance Attitudes Of Knowledge Workers, Kon Shing Kenneth Chung, Liaquat Hossain
Network Structure, Ict Use And Performance Attitudes Of Knowledge Workers, Kon Shing Kenneth Chung, Liaquat Hossain
Faculty of Engineering and Information Sciences - Papers: Part A
In this study, we examine the effect of social network structure and information and communication technologies (ICT) use on performance attitudes of knowledge-intensive workers in dispersed occupational communities. We first develop a theoretical framework and use it to develop a valid and reliable survey instrument. Secondly, we apply structural hole measures (constraint and efficiency) for exploring the association with ICT use and attitudes to performance. Empirical results suggest that density of knowledge workers' professional network is positively associated with ICT use whereas network efficiency is negatively correlated with ICT use at both task and communication-structure level. The findings show that …
Network Measures And Simulation For Knowledge Intensive Work Performance, Kon Shing Kenneth Chung, Liaquat Hossain, Joseph Davis
Network Measures And Simulation For Knowledge Intensive Work Performance, Kon Shing Kenneth Chung, Liaquat Hossain, Joseph Davis
Faculty of Engineering and Information Sciences - Papers: Part A
We describe the process of designing a reliable and valid instrument for collecting network and attribute data. Here, we explore the relationship between social networks structure, information and communication technologies (ICT) use and attitude towards performance in knowledge intensive work. We first develop a model for exploring the inherent relationship between the three concepts based on existing literature. We then develop appropriate item sets for measuring different independent (network structure, ICT use) and dependent variables (performance). We use the reliable item sets along with justifications to construct different phases of our instrument. In doing so, we introduce a simulation approach …
