Semantics-based multiword expression extraction
Authors: Tim Van de Cruys, Begoña Villada Moirón
Venue: Proceedings of the Workshop on a Broader Perspective on Multiword Expressions (2007)

This paper describes a fully unsupervised and automated method for large-scale extraction of multiword expressions (MWEs) from large corpora. The method aims at capturing the non-compositionality of mwes; the intuition is that a noun within a mwe cannot easily be replaced by a semantically similar noun. To implement this intuition, a noun clustering is automatically extracted (using distributional similarity measures), which gives us clusters of semantically related nouns. Next, a number of statistical measures -- based on selectional preferences --- is developed that formalize the intuition of non-compositionality. Our approach has been tested on Dutch, and automatically evaluated using Dutch lexical resources.

Pass the establishment of the excellent courses model in colleges to put forward a new kind of evaluation method.
Carbon Emission of Food Consumption: An Empirical Analysis of China's Residents
Authors: Jing Zhi, Jixi Gao
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

Based on the application of life cycle analysis (LCA), this paper quantifies the impact of food consumption on carbon emission during the period 1990-2006. The results showed that the carbon footprint due to food consumption is increasing. The impact of direct food consumption on carbon emission was just a small part of the life cycle of food consumption, and about 30% of carbon emission was a consequence of food transportation. Meat consumption was the most carbon-intensive food, and compared with 1990, the carbon-density of 1 kg of food increased by 0.52 kgC/kg. The direct impact on carbon emission for urban residents was lower than rural residents, but indirect impact was nearly twice that of rural residents; urban residents consumed more energy due to food transportation and keeping food fresh, the carbon emission related to keeping food fresh was 4 times that of rural residents. This paper provides quantitative evidence of the impact of food consumption on the environment. We suggest that the key to reducing this impact is to improve energy efficiency, especially in the transportation sector.

Authors: Wen Xingqi
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

Tourism business networks are becoming more and more popular in the development of tourism industry. This article analyses the coordination of cooperative activities in tourism business networks by challenging the sustainability of the ‘manipulating’ demand approach in favor of the Value System Continuum in them. It is hypothesized that local tourism businesses must develop new key capabilities in order to face future global competition. The paper focuses on five key capabilities required to manage tourism business networks. The author put forward that capabilities need in tourism business network managing includes: the coordination of cooperation in tourism business networks, value adding relational value production, building the network brand identity, accumulating necessary knowledge and skills, relative independence and multirole of network node, etc.
Improving fuzzy cognitive maps learning through memetic particle swarm optimization
Authors: Y. G. Petalas, K. E. Parsopoulos, M. N. Vrahatis
Venue: Soft Computing - A Fusion of Foundations, Methodologies and Applications (2008)

Fuzzy cognitive maps constitute a neuro-fuzzy modeling methodology that can simulate complex systems accurately. Although their configuration is defined by experts, learning schemes based on evolutionary and swarm intelligence algorithms have been employed for improving their efficiency and effectiveness. This paper comprises an extensive study of the recently proposed swarm intelligence memetic algorithm that combines particle swarm optimization with both deterministic and stochastic local search schemes, for fuzzy cognitive maps learning tasks. Also, a new technique for the adaptation of the memetic schemes, with respect to the available number of function evaluations per application of the local search, is proposed. The memetic learning schemes are applied on four real-life problems and compared with established learning methods based on the standard particle swarm optimization, differential evolution, and genetic algorithms, justifying their superiority.
MDA-Based Framework for Automatic Generation of Consistent Firewall ACLs with NAT
Authors: Sergio Pozo, A. J. Varela-Vaca, Rafael M. Gasca
Venue: Proceedings of the International Conference on Computational Science and Its Applications: Part II (2009)

The design and management of firewall ACLs is a very hard and error-prone task. Part of this complexity comes from the fact that each firewall platform has its own low-level language with a different functionality, syntax, and development environment. Although several high-level languages have been proposed to model firewall access control policies, none of them has been widely adopted by the industry due to a combination of factors: high complexity, no support of important features of firewalls, no common development process, etc. In this paper, a development process for Firewall ACLs based on the Model Driven Architecture (MDA) framework is proposed. The framework supports the market leaders firewall platforms and is user-extensible. The most important access control policy languages are reviewed, with special focus on the development of firewall ACLs. Based on this analysis a new DSL language for firewall ACLs, AFPL2, covering most features other languages do not cover, is proposed. The language is then used as the platform independent meta-model, the first part of the MDA-based framework.
Beyond-Birthday-Bound Security Based on Tweakable Block Cipher
Authors: Kazuhiko Minematsu
Venue: Fast Software Encryption: 16th International Workshop, FSE 2009 Leuven, Belgium, February 22-25, 2009 Revised Selected Papers (2009)

This paper studies how to build a 2n-bit block cipher which is hard to distinguish from a truly random permutation against attacks with q ≈ 2 n/2 queries, i.e., birthday attacks. Unlike previous approaches using pseudorandom functions, we present a simple and efficient proposal using a tweakable block cipher as an internal module. Our proposal is provably secure against birthday attacks, if underlying tweakable block cipher is also secure against birthday attacks. We also study how to build such tweakable block ciphers from ordinary block ciphers, which may be of independent interest.
Towards efficient event aggregation in a decentralized publish-subscribe system
Authors: Jianxia Chen, Lakshmish Ramaswamy, David Lowenthal
Venue: Proceedings of the Third ACM International Conference on Distributed Event-Based Systems (2009)

Recently, decentralized publish-subscribe (pub-sub) systems have gained popularity as a scalable asynchronous messaging paradigm over wide-area networks. Most existing pub-sub systems, however, have been designed with the implicit assumption that published data is clean and accurate. As the pub-sub paradigm is incorporated in real-world applications with human participants, this assumption becomes increasingly invalid due to the inherent noise in the event stream. The noise can take many forms, including redundant, incomplete, inaccurate, and even malicious event messages. This paper explores the distributed computing issues involved in handling event streams with redundant and incomplete messages. Given a distributed broker overlay-based pub-sub system, we present our initial ideas for (1) aggregating event information scattered across multiple messages generated by different publishers and (2) eliminating redundant event messages. Key to our approach is the concept of an event-gatherer---a designated broker in the routing graph that acts as a proxy sink for all messages of a particular event---located at the graph center of the corresponding routing tree. This paper proposes a novel decentralized algorithm to find this graph center. Early results show that the proposed scheme typically reduces the message load by over 60% with less than 25% time overhead to subscribers.
Towards a Modeling Language for Designing Auditory Interfaces
Authors: Mexhid Ferati, Davide Bolchini, Steve Mannheimer
Venue: Proceedings of the 5th International Conference on Universal Access in Human-Computer Interaction. Part III: Applications and Services (2009)

Auditory applications are systems that communicate content, navigation capabilities and functionality mainly via the aural channel, or via a combination of the aural and visual channels, and can support the user interaction in a multimodal fashion as well (e.g. through touch or speech). In this paper, we present the preliminary results of an exploratory research effort aimed at establishing a design modeling language for auditory applications, by extending an existing interactive application design model (IDM, Interactive Dialogue Model) used in the area of hypermedia and information-intensive applications. Our exploratory research capitalizes on previous experience in hypermedia modeling, aural information architectures, and design of auditory applications. We use an auditory application, the Acoustic Edutainment Interface (AEDIN), as a real case study to inform and exemplify the use of the modeling language.

The conclusionis that the main factor to corrosion is acid value, andthen is salt value after desalt, pH value, content of salt,sulphur value and iron ion value. Getting rid of saltfrom crude oil as possible is benefit to equipment, andmonitoring salt value after desalts, pH value couldpredict corrosion.
A Simple Momentum Controller for Humanoid Push Recovery
Authors: Bassam Jalgha, Daniel C. Asmar
Venue: Proceedings of the FIRA RoboWorld Congress 2009 on Advances in Robotics (2009)

While working in a dynamic environment, humanoid robots are subject to unknown forces and disturbances, putting them at risk of falling down and damaging themselves. One mechanism by which humans avoid falling under similar conditions is the human momentum reflex. Although such systems have been devised, the processing requirements are too high to be implemented on small humanoids having microcontroller processing capabilities. This paper presents a simplified momentum controller for fall avoidence. The system is tested on a simulated robot developed under Gazebo as well as under a real humanoid. Results show successful fall avoidance.
A Multiple-Aspects Visualization Tool for Exploring Social Networks
Authors: Jie Gao, Kazuo Misue, Jiro Tanaka
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)

Social network analysis (SNA) has been used to study the relationships between actors in social networks, revealing their features and patterns. In most cases, nodes and edges in graph theory are used to represent actors and relationships, and graph representations are used to visually analyze social networks. However, many visualization tools using network diagrams tend to depict most information about social networks by using the properties of nodes, which result in a visual burden when identifying actors or relationships according to certain properties. There is a lack of tools to support work by investigators to provide insights into multiple-aspect networks. We considered actors, relationships, and communities to be three important elements, and developed a tool called MixVis that integrates a tagcloud, network diagrams, and a list to show the elements. Our tool allows users to explore social networks from elements of interest, and acquire details through links with the three different viewpoints.
Make Learning Fun with Programming Contests
Authors: Gines Garcia-Mateos, Jose Luis Fernandez-Aleman
Venue: Transactions on Edutainment II (2009)

Usually, higher education teachers have to deal with highly populated classes and low levels of motivation. Making more entertaining courses is a good way to overcome these limitations. But, how can fun and entertainment be introduced in a course which is mainly based on a final exam evaluation? We propose a new methodology based on two key ideas: (i) replacing the final exam with a series of activities in a continuous evaluation context; and (ii) making those activities more appealing to the students. We describe an e-learning experience carried out in a second-year programming course for computing majors. The activities are designed as on-line programming competitions, where all students participate and are able to see their global ranking. Experimental results show the effectiveness of this approach. On average, the dropout rate decreased from 72% to 45% while the pass rate doubled.
Ambient Intelligence in Working Environments
Authors: Christian Bühler
Venue: Proceedings of the 5th International on ConferenceUniversal Access in Human-Computer Interaction. Part II: Intelligent and Ubiquitous Interaction Environments (2009)

The concept of ambient intelligence (AmI) has recently been adopted related to living scenarios and denoted as ambient assisted living (AAL). It has received high attention related to the demographic shift and the positive options of care and support for elderly people at home and on the move. However, there exists an equally important field of application related to work. In the context of labour high mobility and flexibility of people is requested. The demand to work up to higher ages complements the situation. People in the workforce develop growing expertise and different abilities over time. They need tailored support systems at work keeping the efficiency and effectiveness and elements of prevention or adjustment to changing abilities. Indeed, environments in industry and at work provide already a high degree of networking and computing infrastructure, much more than in the private sector and can provide a basis for an advanced AmI infrastructure. The idea is discussed within the framework of creating accessible workplaces for people with disabilities. Here, so far a reactive strategy has been followed based on the individual case. Only in case a concrete person with a disability is included in the work force and only in that very moment a workplace adaptation is considered. However, now this reactive strategy is outdated, because today the complete infrastructure needs to be considered to make a workplace accessible. Following an AmI strategy ---ambient assisted working (AAW) provides a flexible approach towards workplace adaptation for all, including people with disabilities and older people in the workforce. In order to use AAW, the process has to start much earlier in a more inclusive way. Without knowing the exact demands of a future worker, the system needs to be designed. The flexible networking character of AmI provides the required flexibility.
Exploiting Data Missingness in Bayesian Network Modeling
Authors: Sérgio Rodrigues De Morais, Alex Aussem
Venue: Proceedings of the 8th International Symposium on Intelligent Data Analysis: Advances in Intelligent Data Analysis VIII (2009)

This paper proposes a framework built on the use of Bayesian networks (BN) for representing statistical dependencies between the existing random variables and additional dummy boolean variables, which represent the presence/absence of the respective random variable value. We show how augmenting the BN with these additional variables helps pinpoint the mechanism through which missing data contributes to the classification task. The missing data mechanism is thus explicitly taken into account to predict the class variable using the data at hand. Extensive experiments on synthetic and real-world incomplete data sets reveals that the missingness information improves classification accuracy.
Privacy Preserving Publication of Moving Object Data
Authors: Francesco Bonchi
Venue: Privacy in Location-Based Applications: Research Issues and Emerging Trends (2009)

The increasing availability of space-time trajectories left by location-aware devices is expected to enable novel classes of applications where the discovery of consumable, concise, and actionable knowledge is the key step. However, the analysis of mobility data is a critic task by the privacy point of view: in fact, the peculiar nature of location data might enable intrusive inferences in the life of the individuals whose data is analyzed. It is thus important to develop privacy-preserving techniques for the publication and the analysis of mobility data.This chapter provides a brief survey of the research on anonymity preserving data publishing of moving objects databases.While only few papers so far have tackled the problem of anonymity in the off-line case of publication of a moving objects database, rather large body of work has been developed for anonymity on relational data on one side, and for location privacy in the on-line, dynamic context of location based services (LBS), on the other side. In this chapter we first briefly review the basic concepts of k-anonymity on relational data. Then we focus on the body of research about privacy in LBS: we try to identify some useful concepts for our static context, while highlighting the differences, and discussing the inapplicability of some of the LBS solutions to the static case. Next we present in details some of the papers that recently have attacked the problem of moving objects anonymization in the static context. We discuss in details the problems addressed and the solutions proposed, highlighting merits and limits of each work, as well as the various problems still open.
Aesthetic Coloring for Complex Layout Using Genetic Algorithm
Authors: Quan Zhang, Wenke Kang, Chenglei Zhao, Xinguo Ming
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 03 (2009)

Aesthetic coloring is most important in computer visual arts while it is affected by complex factors such as color number, color attribute value, area color covered, and color pairs. In previous researches many intelligent evaluation systems have been presented for simple layout. Color design for complex layout by artificial intelligent is still an unsolved problem. In this study GA was used to solve the complex optimization problem. To the question Moon and Spencer’s aesthetic measure was used to construct the optimization model. The modified GA was introduced in the intelligent program. And an illustrative example was analyzed in the end. Results showed that the aesthetic coloring system can automatically create beautiful color images in a short time. Future work should focus on improving the aesthetic measure model.

One Telemedical Solution in Bulgaria
Authors: P. Mihova, J. Vinarova, I. Pendzhurov
Venue: Proceedings of the 12th Conference on Artificial Intelligence in Medicine: Artificial Intelligence in Medicine (2009)

A new arena of healthcare is emerging, because physicians, hospitals, financial health planners and administrators are coming together in a single highly integrated and coordinated virtual health organization.The mission of Telemedicine is to provide medical services independently of geographical distances between the involved sites. Patients can get access to medical expertise that may not be available at the patients' site through Telemedicine. Experience over the last decade has shown that the goals of Telemedicine are not automatically reached by the introduction and use of particular new technologies per se, but rather require the implementation of integral services and specialized information systems.Software Teleconsult aims are to provide logistic and telemedical services between two distant hospitals on the territory of Bulgaria. The objectives of this development are to combine medicine field, e-health and informatics research so as to share information and experience in order to perform the best patient services at a reasonable price.
