Hime: Mining And Ensembling Heterogeneous Information For Protein Interaction Predictions, Huaming Chen, Yaochu Jin, Lei Wang, Chi-Hung Chi, Jun Shen
Faculty of Engineering and Information Sciences - Papers: Part B
esearch on protein-protein interactions (PPIs) data paves the way towards understanding the mechanisms of infectious diseases, however improving the prediction performance of PPIs of inter-species remains a challenge. Since one single type of sequence data such as amino acid composition may be deficient for high-quality prediction of protein interactions, we have investigated a broader range of heterogeneous information of sequences data. This paper proposes a novel framework for PPIs prediction based on Heterogeneous Information Mining and Ensembling (HIME) process to effectively learn from the interaction data. In particular, the proposed approach introduces an ensemble process together with substantial features that …

Micro learning aims to assist users in making good use of smaller chunks of spare time and provides an effective online learning service. However, to provide such personalized online services on the Web, a number of information overload challenges persist. Effectively and precisely mining and extracting valuable information from massive and redundant information is a significant preprocessing procedure for personalizing online services. In this study, we propose a deep sequence labelling model for locating, extracting, and classifying key information for micro learning services. The proposed model is general and combines the advantages of different types of classical neural network. Early …

Attention-Based Knowledge Tracing With Heterogeneous Information Network Embedding, Nan Zhang, Ye Du, Ke Deng, Li Li, Jun Shen, Geng Sun
Faculty of Engineering and Information Sciences - Papers: Part B
Knowledge tracing is a key area of research contributing to personalized education. In recent times, deep knowledge tracing has achieved great success. However, the sparsity of students’ practice data still limits the performance and application of knowledge tracing. An additional complication is that the contribution of the answer record to the current knowledge state is different at each time step. To solve these problems, we propose Attention-based Knowledge Tracing with Heterogeneous Information Network Embedding (AKTHE). First, we describe questions and their attributes with a heterogeneous information network and generate meaningful node embeddings. Second, we capture the relevance of historical data …

A New Approach To Keep The Privacy Information Of The Signer In A Digital Signature Scheme, Dung Hoang Duong, Willy Susilo, Viet Cuong Trinh
Faculty of Engineering and Information Sciences - Papers: Part B
In modern applications, such as Electronic Voting, e-Health, e-Cash, there is a need that the validity of a signature should be verified by only one responsible person. This is opposite to the traditional digital signature scheme where anybody can verify a signature. There have been several solutions for this problem, the first one is we combine a signature scheme with an encryption scheme; the second one is to use the group signature; and the last one is to use the strong designated verifier signature scheme with the undeniable property. In this paper, we extend the traditional digital signature scheme to …
Facilitating Application-Aware Bandwidth Allocation In The Cloud With One-Step-Ahead Traffic Information, Dian Shen, Junzhou Luo, Fang Dong, Jiahui Jin, Junxue Zhang, Jun Shen
Facilitating Application-Aware Bandwidth Allocation In The Cloud With One-Step-Ahead Traffic Information, Dian Shen, Junzhou Luo, Fang Dong, Jiahui Jin, Junxue Zhang, Jun Shen
Faculty of Engineering and Information Sciences - Papers: Part B
Bandwidth allocation to virtual machines (VMs) has a significant impact on the performance of communication-intensive big data applications hosted in VMs. It is crucial to accurately determine how much bandwidth to be reserved for VMs and when to adjust it. Past approaches typically resort to predicting the long-term network demands of applications for bandwidth allocation. However, lacking of prediction accuracy, these methods lead to the unpredictable application performance. Recently, it is conceded that the network demands of applications can only be accurately derived right before each of their execution phases. Hence, it is challenging to timely allocate the bandwidth to …
A Cost-Effective Software Testing Strategy Employing Online Feedback Information, Zhiquan Zhou, Arnaldo Sinaga, Willy Susilo, Lei Zhao, Kai-Yuan Cai
A Cost-Effective Software Testing Strategy Employing Online Feedback Information, Zhiquan Zhou, Arnaldo Sinaga, Willy Susilo, Lei Zhao, Kai-Yuan Cai
Faculty of Engineering and Information Sciences - Papers: Part B
An online partitioning strategy is presented, in which test cases are selected based on feedback information collected during the testing process. The strategy differs from con- ventional approaches because the partitioning is performed online rather than off-line and because the partitioning is not based on program code or specifications. It can, therefore, be implemented in the absence of the source code or specification of the program under test. The cost-effectiveness of the proposed strategy has been empirically investigated with a set of subject programs, namely, SPACE, SED, GREP, and the Siemens Suite of Programs. The results demonstrate that the proposed …

The use of simulation to predict building energy performance has been shown to have significant benefits in terms of reducing energy consumption and greenhouse gas emissions. However, in terms of implementation, the process can be disjointed and messy, with a lack of integration between architects and engineers. For the process of creating a building energy simulation to be more efficient, a seamless transition from an architectural design to an energy model is required. This paper highlights some of the practical issues manifest in the process of data exchange for energy analysis. It presents a proposed workflow for the exchange of …

Revisiting An Information Infrastructure For Development: Exploring The Cost Of Information In Pacific Island Development, William J. Tibben
Revisiting An Information Infrastructure For Development: Exploring The Cost Of Information In Pacific Island Development, William J. Tibben
Faculty of Engineering and Information Sciences - Papers: Part A
Information and communication technologies (ICTs) have been associated with development programmes for many decades. A theme of Lamberton's commentary on such initiatives focuses on the lack of attention given to information as a key factor in the development process. His writing reiterated a number of arguments that he saw as being fundamental to the application of an information perspective to development issues. With a focus on agricultural development policy in the Pacific region, the paper uses a number of propositions that are suggested by Lamberton to analyse contemporary development initiatives in Pacific Island agriculture. These propositions focus attention on information …

Modelling Variations In Hospital Service Delivery Based On Real Time Locating Information, Nagesh Shukla, John Keast, Darek Ceglarek
Modelling Variations In Hospital Service Delivery Based On Real Time Locating Information, Nagesh Shukla, John Keast, Darek Ceglarek
Nagesh Shukla
Variations in service delivery have been identified as a major challenge to the success of process improvement studies in service departments of hospital such as radiology. Largely, these variations are due to inherent system level factors, i.e., system variations such as unavailability of resources (nurse, bed, doctors, and equipment). These system variations are largely unnecessary/unwarranted and mostly lead to longer waiting times, delays, and lowered productivity of the service units. There is limited research on identifying system variations and modelling them for service improvements within hospital. Therefore, this paper proposes a modelling methodology to model system variations in radiology based …
Factor Analytic Mixed Models For The Provision Of Grower Information From National Crop Variety Testing Programs, Alison B. Smith, Aanandini Ganesalingam, Haydn Kuchel, Brian R. Cullis
Factor Analytic Mixed Models For The Provision Of Grower Information From National Crop Variety Testing Programs, Alison B. Smith, Aanandini Ganesalingam, Haydn Kuchel, Brian R. Cullis
Faculty of Engineering and Information Sciences - Papers: Part A
Crop variety testing programs are conducted in many countries world-wide. Within each program, data are combined across locations and seasons, and analysed in order to provide information to assist growers in choosing the best varieties for their conditions. Despite major advances in the statistical analysis of multi-environment trial data, such methodology has not been adopted within national variety testing programs. The most commonly used approach involves a variance component model that includes variety and environment main effects, and variety by environment ( VxE ) interaction effects. The variety predictions obtained from such an analysis, and subsequently reported to growers, are …

Information Technology And Open Innovation: A Strategic Alignment Perspective, Tingru Cui, Hua Ye, Hock Hai Teo, Jizhen Li
Faculty of Engineering and Information Sciences - Papers: Part A
Advances in information technology (IT) have enabled firms to increasingly rely on open innovation. Although researchers and practitioners are interested in this phenomenon, there is a lack of theoretically driven research on how IT impacts organizational open innovation performance. Drawing on the strategic IT alignment perspective and related literature, we proposed a model to explain the performance of organizational open innovation; i.e., the alignment between IT strategies and the openness of open innovation strategies results in different outcomes for open innovation. Through the analysis of data from 225 firms in China, we found that the alignment between IT flexibility and …

Action Research In Emerging Technologies In Health Information Systems: Creating A Mobile Information Environment In A Hospital Ward, Linda Dawson, Julie Fisher, Stephen Weeding, Liza Heslop, Andrew Howard
Associate Professor Linda Dawson
Wireless networks, mobile devices and associated applications are key emerging technologies ideal for nomadic workers such as clinicians in hospital ward settings. These mobile information environments can potentially enhance clinicians' use of patient management and clinical systems by providing decision support and clinical information at the bedside or point of care. Such technologies need to be critically assessed in a hospital environment for their wider potential and application for delivery of information at the point of care. This paper describes the use of action research methods in a project which analysed an existing clinical Information Communication Technology (ICT) environment in …

Towards A Framework For Mobile Information Environments: A Hospital-Based Example, Linda Dawson, Sea Ling, Maria Indrawan, Stephen Weeding, Juanita Femando
Associate Professor Linda Dawson
We propose a conceptual framework to describe and understand mobile information environments. In our proposal, such an environment can be categorised into different abstraction levels or communities: user level, workflow level, device level and architecture level. A hospital-based example is then used as an illustration for the proposed framework.

Emerging Of Academic Information Search System With Ontology-Based Approach, Norasykin Mohd Zaid, Sim Kim Lau
Faculty of Engineering and Information Sciences - Papers: Part A
This paper describes the comparison of ontology development tools for development of academic information search system that assists inexperienced research students at a local university in Malaysia to search for academic resources in the local language context (Bahasa Malaysia). The cohort of inexperienced research students faces two main problems when using current system comprises of keyword search. Firstly the language barrier-limiting students' capabilities to conduct keyword search in foreign language (such as English). Secondly limited research experience in querying often results in obtaining irrelevant search results. The proposed semantic search system aims to apply ontology-based search to overcome the above …

A Review Of Data Quality Assessment Methods For Public Health Information Systems, Hong Chen, David Hailey, Ning Wang, Ping Yu
A Review Of Data Quality Assessment Methods For Public Health Information Systems, Hong Chen, David Hailey, Ning Wang, Ping Yu
Faculty of Engineering and Information Sciences - Papers: Part A
High quality data and effective data quality assessment are required for accurately evaluating the impact of public health interventions and measuring public health outcomes. Data, data use, and data collection process, as the three dimensions of data quality, all need to be assessed for overall data quality assessment. We reviewed current data quality assessment methods. The relevant study was identified in major databases and well-known institutional websites. We found the dimension of data was most frequently assessed. Completeness, accuracy, and timeliness were the three most-used attributes among a total of 49 attributes of data quality. The major quantitative assessment methods …
The Instructional Information Processing Account Of Digital Computation, Nir Fresco, Marty J. Wolf
The Instructional Information Processing Account Of Digital Computation, Nir Fresco, Marty J. Wolf
Faculty of Engineering and Information Sciences - Papers: Part A
What is nontrivial digital computation?It is the processing of discrete data through discrete state transitions in accordance with finite instructional information. The motivation for our account is that many previous attempts to answer this question are inadequate, and also that this account accords with the common intuition that digital computation is a type of information processing. We use the notion of reachability in a graph to defend this characterization in memory-based systems and underscore the importance of instructional information for digital computation. We argue that our account evaluates positively against adequacy criteria for accounts of computation.
The Information In Aggregate Data, David Steel, Eric Beh, Raymond Chambers
The Information In Aggregate Data, David Steel, Eric Beh, Raymond Chambers
Professor David Steel
Ecological inference attempts to draw conclusions concerning individual-level relationships using data in the form of aggregates for groups in the population. The groups are often geographically defined. A fundamental statistical issue is how much information aggregate data contain concerning the relationships and parameters that we are trying to estimate. The information affects the standard errors of estimates as well as the power of any tests of hypothesis. It also affects the ability to tell, from the aggregate data, which different models under consideration are supported by the data. In this chapter likelihood-based methods are considered. We show in general how …
Is 'Community' Important For Community Information Systems?, Alison E. Freeman, Peter Hyland, Mark Freeman, Karlheinz Kautz
Is 'Community' Important For Community Information Systems?, Alison E. Freeman, Peter Hyland, Mark Freeman, Karlheinz Kautz
Faculty of Engineering and Information Sciences - Papers: Part A
Community information systems have the power to transform communities. However, without fully understanding the pre-requisite factors affecting community information system viability, and the complex relationships between these factors, communities struggle to manage such projects in a way that leads to viable systems that deliver real benefits. This paper develops and presents a Model of Community Information System Viability Pre-requisite Factors, based on both existing literature and the study of three community information system projects. This Model represents the generic factors that inform viability (i.e. leadership, active membership, funding, awareness, and system design and functionality), and also considers the impact of …
Information Processing As An Account Of Concrete Digital Computation, Nir Fresco
Information Processing As An Account Of Concrete Digital Computation, Nir Fresco
Faculty of Engineering and Information Sciences - Papers: Part A
It is common in cognitive science to equate computation (and in particular digital computation) with information processing. Yet, it is hard to find a comprehensive explicit account of concrete digital computation in information processing terms. An information processing account seems like a natural candidate to explain digital computation. But when 'information' comes under scrutiny, this account becomes a less obvious candidate. Four interpretations of information are examined here as the basis for an information processing account of digital computation, namely Shannon information, algorithmic information, factual information and instructional information. I argue that any plausible account of concrete computation has to …
Instructional Information Processing: Replies Considered, Nir Fresco
Instructional Information Processing: Replies Considered, Nir Fresco
Faculty of Engineering and Information Sciences - Papers: Part A
Wolf and White address different aspects of the paper, and in this present reply, space only permits making two brief remarks. Starting with White's intriguing observation, digital computation without erasing information is possible. This clearly has important implications for real-world digital computing systems, since they can be designed and constructed in a more energy-efficient manner, if information erasure operations are kept to a minimum. Yet, avoiding information erasure operations completely in the course of computation is another matter. At least prima facie, this introduces difficulties relating to memory storage. Information is conveyed by data and (particularly persistent) data in computing …

Faculty of Engineering and Information Sciences - Papers: Part A
Building Information Modelling (BIM) has been widely acknowledged as an emerging technological and procedural shift within the Architecture, Engineering and Construction (AEC) industry. BIM represents a methodology to manage the building design and project data in digital format throughout a building lifecycle. With the implementation of BIM, the design, construction and operation processes can be better streamlined to improve project efficiency. Because of its far-reaching benefits, there is a current push for BIM by governments worldwide, including Australia. However, a significant lack of the understanding of BIM and industry readiness has been identified as a major hindrance; hence, there is …
