Recommender Systems on the Web: A Model-Driven Approach
Authors: Gonzalo Rojas, Francisco Domínguez, Stefano Salvatori
Venue: Proceedings of the 10th International Conference on E-Commerce and Web Technologies (2009)

Recommendation techniques have been increasingly incorporated in e-commerce applications, supporting clients in identifying those items that best fit their needs. Unfortunately, little effort has been made to integrate these techniques into methodological proposals of Web development, discouraging the adoption of engineering approaches to face the complexity of recommender systems. This paper introduces a proposal to develop Web-based recommender systems from a model-driven perspective, specifying the elements of recommendation algorithms from a high abstraction level. Adopting the item-to-item approach, this proposal adopts the conceptual models of an existing Web development process to represent the preferences of users for different items, the similarity between obtained from different algorithms, and the selection and ordering of the recommended items according to a predicted rating value. Along with systematizing the development of these systems, this approach permits to evaluate different algorithms with minor changes at conceptual level, simplifying their mapping to final implementations.

Authors: Hong Sun, Karen Lemmens, Tim Van den Bulcke, Kristof Engelen, Bart De Moor, Kathleen Marchal
Venue: Bioinformatics (2009)

Motivation: We developed ViTraM, a tool that allows visualizing overlapping transcriptional modules in an intuitive way. By visualizing not only the genes and the experiments in which the genes are co-expressed, but also additional properties of the modules such as the regulators and regulatory motifs that are responsible for the observed co-expression, ViTraM can assist in the biological analysis and interpretation of the output of module detection tools. Availability: The ViTraM software is platform-independent.

Research on Distributed Information Resources Management of Virtual Enterprise
Authors: Min Huang, Bo Sun
Venue: Proceedings of the 2009 IITA International Conference on Services Science, Management and Engineering (2009)

As new organizing form, virtual enterprise has developed rapidly in many industries and domains. For virtual enterprise has some especial features such as resource dispersing, member diversity, organization dynamics and flexibility and so on, information resources management of it has much more difficulties. According to the features of virtual enterprise, the model of a distributed information resources management system based on mobile agents has been designed, and the model of mobile agent is discussed in detail. Some methods and mechanisms about uniform description, access, discovery of resource in the resource management of virtual enterprise have been researched deeply, and some tests have been done on the prototype system based on the model and methods presented in the paper, which provides some references and advises to solving this problem.
Safe composition of non-monotonic features
Authors: Martin Kuhlemann, Don Batory, Christian Kästner
Venue: Proceedings of the eighth international conference on Generative programming and component engineering (2009)

Programs can be composed from features. We want to verify automatically that all legal combinations of features can be composed safely without errors. Prior work on this problem assumed that features add code monotonically. We generalize prior work to enable features to add and remove code, describe our analyses and implementation, and review case studies. We observe that more expressive features increase the complexity of developed programs rapidly -- up to the point where tools and automated concepts as presented in this paper are indispensable for verification.
Passivity-Based Adaptive Chaos Control of a New 3D Chaotic System with Uncertain Parameters
Authors: Zhou Xiaobing, Zhang Jinfu, Jiang Murong
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 03 (2009)

In this paper, we propose a novel simple adaptive controller for the control of a new 3D chaotic system with uncertain parameters. With the study of the property of a passive system, the corresponding necessary condition under which the new uncertain chaotic 3D system can be equivalent to a passive system via smooth state feedback is proposed. It is found that the new system transformed by this new uncertain 3D chaotic system can be globally asymptotically stabilized at each equilibrium point of its uncontrolled system, provided that the controller and the parameter estimation update law were suitable designed. In addition, simulation results indicate that the proposed chaos control method is very effective and feasible in this new 3D chaotic system.
Possibility of Participatory Design
Authors: Makoto Okamoto
Venue: Proceedings of the 1st International Conference on Human Centered Design: Held as Part of HCI International 2009 (2009)

Participatory design has attracted attention as a design method in recent years. Scenario or Inclusive Design is one way to make users participate in the design process. In this paper, I report on some case studies in which the visually-impaired participated in the design process. The sighted designer worked together with the visually-impaired wearing eye masks. The visually-impaired could tell designers some problems in their lives or their demand which was difficult to express in words.
Equivalence Knowledge Cumularspharolith and IV-type Completeness of the Knowledge Base K in R-logic CR
Authors: Yalin Zheng, Yong Li
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 01 (2009)

By casting off the direct restriction of topological structure,this paper presents another matching scheme between the input $A^\ast $ and the knowledge $A \to B$ based on the equivalence relation $\mathcal{R}$ on formulae set $\mathcal{F(S)}$ and the corresponding equivalence classification \begin{equation*}\mathcal{F(S)}/\mathcal{R}=\{ [A]_\mathcal{R}\ | A \in\mathcal{F(S)} \}\end{equation*} therefore, obtains another algorithm of approximate reasoning -- the IV-type $\mathcal{R}-$ algorithm. The paper presents the IV-type completeness and the IV-type perfection of the knowledge base $\mathcal{K}$ in $\mathcal{R}-$logic $\mathbb{C}_{\mathcal{R}}$ and regular $\mathcal{R}-$logic $\mathbb{C}_{\mathcal{R}}$.

Loss of Genetic Variation in Hatchery Produced Haliotis Asinina Using AFLP and Allozyme Markers
Authors: Zhongbao Li, Jiyuan Zhang, Ji Li, Lina Wang
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 01 (2009)

The genetic diversity and differentiation between wild and hatchery Haliotis asinina populations were tested by allozyme and AFLP techniques. The results from allozyme technique showed that there was a decline in mean number of alleles per locus, percentage of polymorphic loci and observed heterozygosity and a change in allele frequency in three loci, SDH-1, AAT-1 and EST-1. Allelic richness, percentage of polymorphic loci and observed heterozygosities ranged from 1.4 (0.2) to 1.2 (0.1), from 30 to 20, from 0.150 (0.104) to 0.140 (0.103) within both wild and hatchery H.asinina populations, respectively. Compared to wild population, the hatchery population from AFLP technique also showed that there was a reduction in effective number of allele, gene diversity, shannon's information index and percentage of polymorphic loci, they ranged from 1.5215 to 1.4675, from 0.2932 to 0.2609, from 0.4252 to 0.3778 and from 69.93 to 62.09, respectively. But low level of differentiation was found between wild and hatchery H.asinina populations. It is inferred that it is small effective population size inbreeding that results in loss of genetic variation in the hatchery H.asinina seed.
Hawk-Eye: Augmented reality in sports broadcasting and officiating
Authors: Paul McIlroy
Venue: Proceedings of the 7th IEEE/ACM International Symposium on Mixed and Augmented Reality (2008)

Hawk-Eye is the camera based ball-tracking system that enables players to challenge line-calling decisions on the courts of major tennis events such as Wimbledon. Paul McIlroy uncovers the machine vision technology behind the verdict on the big screen. He describes how the International Tennis Federation tested and accredited the system as an officiating aid and the technical challenges overcome to meet their stringent criteria for accuracy and reliability. He also reveals the pitfalls encountered in taking a vision system out of the lab and attempting to integrate it into the unforgiving world of broadcast television in remote corners of the earth.

Authors: Hao Hanzhou, Jin Menggui, Liu Chengwu, Li Ruiming, Wang Zhinong
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 03 (2009)

The DD2005-03 sequential extraction method, developed for the analysis of heavy metals in soil, was applied to 234 soil samples covering the area of the Henan Province representative agriculture soil. On average, the order of Cd in each fraction was Exchangeable (27.3%) > Weakly bound to organic matter (22.7%) > Strongly bound to organic matter (16.4%) > Residual (15.1%) > Carbonate (12.1%) > Fe/Mn oxide bound (4.5%) > Water soluble (2.0%), Zn was Residual (66.3%) > Fe/Mn oxide bound (10.9%) > Weakly bound to organic matter (9.4%) > Exchangeable (6.0%) > Strongly bound to organic matter (3.9%) > Carbonate (2.9%) > Water soluble (0.6%). The accuracy of the sequential extraction was judged by the relative error (RE). RE for Cd ranged from 0 to 45% with mean 16.3%.RE for Zn ranged from 0.1-11.4% with mean 3.4%. On average, bioavailability index (BI) for Cd and Zn is 39.1% and 9.0% respectively. The mobility of the elements in the order Cd > Zn corresponds with the plant- availability of individual elements.

Marginal Partial Likelihood Approach in the Cox Model with Non-ignorable Missing Covariates
Authors: Liu Huanbin, Sun Liuquan
Venue: Proceedings of the 2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009) (2009)

Marginal partial likelihood approach is used for estimating the parameters for the Cox model with missing covariates and a non-ignorable missing data mechanism. An efficient algorithm based on Markov chain Monte Carlo stochastic approximation is proposed to solve the resulting estimating equations. Simulation studies show that the proposed estimation procedure works well and gives accurate estimates and their variance estimates. We also illustrate the method with a melanoma data set.
Networking Dual-Surveillance/Dual-Telepaths to Sustain Parking Structures
Authors: Li-Yen Hsu
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

oday, the demand for flexible, large-scale parking structures is increasing all over the globe. To enhance safety or to sustain development, dual-surveillance based supervisory control and data acquisition (SCADA) networks are modeled to be spatially integrated with a helix circulation pattern. Moreover, reliable wireless area communication is systematically organized to counter the effects of an adversary’s multipath radio. Their sequential-order, integrative connectivity, and reliability provide the benefits of efficient maintenance, energy savings, environmental control, safety/security, and human-care image promotion, which is due to their effective dual sensing, systematic fault-tolerance, and integrative management in area perspectives. Such systems can potentially reduce the loss due to fire-protection, such as water damage, and can help promote flexible land-use, including express delivery stations that use wireless or radio frequency identification (RFID) applications. Therefore, their adaptability and reliability can promote sustainable urban development.
Play-Personas: Behaviours and Belief Systems in User-Centred Game Design
Authors: Alessandro Canossa, Anders Drachen
Venue: Proceedings of the 12th IFIP TC 13 International Conference on Human-Computer Interaction: Part II (2009)

Game designers attempt to ignite affective, emotional responses from players via engineering game designs to incite definite user experiences. Theories of emotion state that definite emotional responses are individual, and caused by the individual interaction sequence or history. Engendering desired emotions in the audience of traditional audiovisual media is a considerable challenge; however it is potentially even more difficult to achieve the same goal for the audience of interactive entertainment, because a substantial degree of control rests in the hand of the end user rather than the designer. This paper presents a possible solution to the challenge of integrating the user in the design of interactive entertainment such as computer games by employing the "persona" framework introduced by Alan Cooper. This approach is already in use in interaction design. The method can be improved by complementing the traditional narrative description of personas with quantitative, data-oriented models of predicted patterns of user behaviour for a specific computer game Additionally, persona constructs can be applied both as design-oriented metaphors during the development of games, and as analytical lenses to existing games, e.g. for evaluation of patterns of player behaviour.
Requirements Reasoning for Distributed Requirements Analysis Using Semantic Wiki
Authors: Peng Liang, Paris Avgeriou, Viktor Clerc
Venue: Proceedings of the 2009 Fourth IEEE International Conference on Global Software Engineering (2009)

In large-scale collaborative software projects, thousands of requirements with complex interdependencies and different granularity spreading in different levels are elicited, documented, and evolved during the project lifecycle. Non-technical stakeholders involved in requirements engineering activities rarely apply formal techniques; therefore it is infeasible to automatically detect problems in requirements. This situation becomes even worse in a distributed context when all sites are responsible to maintain their own requirements list using various requirements models and management tools, and the detection of requirements problems across multiple sites is error-prone, and unaffordable if performed manually. This paper proposes an integrated approach of basing distributed requirements analysis on semantic wiki by requirements reasoning. First, the functions concerning reasoning support provided by semantic wiki for requirements analysis are proposed. Second, the underlying requirements rationale model for requirements reasoning is presented with sample reasoning rules. Third, our rationale model is mapped to the WinWin requirements negotiation model which further adds to its credibility.
Introspection-Based Verification and Validation
Authors: Hans P. Zima, Mark L. James
Venue: Proceedings of the Third IEEE International Conference on Space Mission Challenges for Information Technology (2009)

Future missions of deep-space exploration will require an on-board computational capability that can support autonomy and enhanced science processing. The integration of emerging commodity multi-core technology into space-borne systems can provide the required performance; however, protecting such systems against faults has become a critical research issue. In this paper we present an approach to fault tolerance based on a newly developed introspection framework thatsupports runtime monitoring of program execution and feedback-oriented recovery. We discuss the relationship ofthis approach to traditional Verification and Validation (V&V) and propose methods for the automatic generation of assertions from static anddynamic analysis.

Authors: Emma Nuraihan Mior Ibrahim, Nor Laila Noor
Venue: Proceedings of the Symposium on Human Interface 2009 on Human Interface and the Management of Information. Information and Interaction. Part II: Held as part of HCI International 2009 (2009)

The global nature of the Internet raises questions about variety of ways, whether and how trust is established that guide people's behavior and beliefs. This study explores on the understanding of trust from the non technical perspectives in the context of web mediated information environment (W-MIE); conceptualized within the notion of online legitimacy [1]. We take up the problem of how to enhance the trustworthiness of information on the web through the design deployment that can be rationalized and understood by the ordinary users. The paper highlights four dimensions of design elements that make up the Institutional Trust Inducing Features framework [2] which warrants increased attention. This paper is merely situating our comments in designing information artifact within a sensitive context that is culturally imbued beyond the typical security scope but rather the conceptual understand-ing on how user's engage with information interactions.

Authors: Sun Xuekang, Gu Wanyi, Xiao Xingquan, Xu Baocheng, Guo Zhigang
Venue: Proceedings of the 2009 WASE International Conference on Information Engineering - Volume 02 (2009)

Multipath routing which has great potential to improve network characteristics for mobile wireless networks is one of central problems nowadays. Since most of the proposed multipath algorithms are On-Demand based, they need extra feedback information that lead the delay to grow. In this paper, we propose a proactive Multipath Optimized Link State Routing Protocol (MOLSR) based on OLSR(Optimized Link State Routing Protocol), which introduces the cross-layer concept as well as the node discovery algorithm employed to discover every node on the route to build disjoint path. Simulation results show that MOLSR achieves lower delay and packet drop ratio with little more overhead than the classic OLSR algorithm.

Authors: Jaime Moreno-Llorena, Xavier Alamán Roldán, Ruth Cobos Perez
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part III: Ubiquitous and Intelligent Interaction (2009)

SKC is a prototype system for knowledge management in the Web by means of semantic information without supervision and tries to select the knowledge contained in the system by paying attention to its use. This paper explains user activity analysis in order to find out their interest for knowledge elements in the system, and the application of this interest for users classification and knowledge identification for their interest, inside and outside SKC. As a result a model for user interest based on interaction is obtained.
XQPage: A Webpage Programming Language Based on XQuery
Authors: Huitao Zhang, Husheng Liao, Zhiming Gui
Venue: Proceedings of the 2009 First International Workshop on Database Technology and Applications (2009)

The paper proposes a new webpage programming language that is based on XQuery: XQPage. It augments the abilities of XQuery to support the Document Object Model in browser, and to support the event response mechanism of DOM objects through extending the updating facility of XQuery. In contrast to the traditional ways using XQuery in webpage currently, it does not need any host language and can be directly applied in webpage design. It enables developers to construct, modify and operate webpage in native XML processing language. The demonstration illustrates that it is flexible, efficient, easy to use and can meet the requirement of most webpage programming.
Assistive Tools to Reach European Accessibility Web Standards
Authors: Sonia Colas, Nicolas Monmarché, Mohamed Slimane
Venue: Proceedings of the 5th International Conference on Universal Access in Human-Computer Interaction. Part III: Applications and Services (2009)

People with disabilities can use assistive technology to browse the Internet, but web sites must respect WCAG recommendations in order to be easily visited. Creating accessible web sites can be a difficult task for small communities because web sites are sometimes managed by beginner webmasters. We have developed tools for helping them to reach accessibility compliance. It can be used to create or modify a web site in order to reach, step-by-step, a better level of accessibility. It is designed to assess the compliance to HTML, CSS and WCAG specifications. Our tool integrates the UWEM specifications published by the WAB Cluster for harmonizing assessment methods in Europe.
