Distributed Service - Oriented Architecture for Information Extraction System "Semanta"
Authors: Lukasz Jastrzebski, Maciej Piasecki, Grzegorz Strzelecki
Venue: Proceedings of the 5th International Conference on Intelligent Systems Design and Applications (2005)

Our objective is to provide a flexible, scalable, distributed architecture that assures a high performance for Information Extraction (IE) systems working in Internet. The architecture is based on both the general paradigm of the Service-Oriented Architecture (in the sense of [18]), clientserver approach and strong separation of concerns between storage and processing components. An experimental IE system, named Semanta, utilising the proposed architecture is also presented. In the following document, we describe five main Semanta services, which are Web User Interface (WebUI), Web Crawler Service (WCS), Parsing Service (PS), IE Service and Manager.

Online and Offline Character Recognition Using Alignment to Prototypes
Authors: Jonathan Alon, Vassilis Athitsos, Stan Sclaroff
Venue: Proceedings of the Eighth International Conference on Document Analysis and Recognition (2005)

Nearest neighbor classifiers are simple to implement, yet they can model complex non-parametric distributions, and provide state-of-the-art recognition accuracy in OCR databases. At the same time, they may be too slow for practical character recognition, especially when they rely on similarity measures that require computationally expensive pairwise alignments between characters. This paper proposes an efficient method for computing an approximate similarity score between two characters based on their exact alignment to a small number of prototypes. The proposed method is applied to both online and offline character recognition, where similarity is based on widely used and computationally expensive alignment methods, i.e., Dynamic Time Warping and the Hungarian method respectively. In both cases significant recognition speedup is obtained at the expense of only a minor increase in recognition error.
Formal Communication Semantics of SystemC^FL
Authors: K. L. Man
Venue: Proceedings of the 8th Euromicro Conference on Digital System Design (2005)

In this paper, we define a formal communication semantics for SystemCFL that deals with concurrency and interaction. The communication semantics of Systemv C^FL is formally defined in a standard structured operational semantics (SOS) style. The correctness of the proposed communication semantics of SystemCFL is also validated. A case study (RPC protocol with refinement) is given to illustrate the use of the newly developed communication semantics of SystemCFL .
SEAT-LA: A Soft Error Analysis Tool for Combinational Logic
Authors: R. Rajaraman, J. S. Kim, N. Vijaykrishnan, Y. Xie, M. J. Irwin
Venue: Proceedings of the 19th International Conference on VLSI Design held jointly with 5th International Conference on Embedded Systems Design (2006)

Radiation induced soft errors in combinational logic is expected to become as important as directly induced errors on state elements. Consequently, it has become important to develop techniques to quickly and accurately predict soft error rates (SER) in logic circuits. In this paper, we propose a new approach, which can be applied to designs that use cell libraries characterized for soft error analysis and utilizes analytical equations to model the propagation of a voltage pulse to the input of a state element. The average error of the SER estimates using our approach compared to the estimates obtained using circuit level simulations is 6.5% while providing an average speed up of 15000. We have demonstrated the scalability of our approach using designs from the ISCAS-85 benchmarks.
Time synchronization attacks in sensor networks
Authors: Michael Manzo, Tanya Roosta, Shankar Sastry
Venue: Proceedings of the 3rd ACM workshop on Security of ad hoc and sensor networks (2005)

Time synchronization is a critical building block in distributed wireless sensor networks. Because sensor nodes may be severely resource-constrained, traditional time-synchronization protocols cannot be used in sensor networks. Various time-synchronization protocols tailored for such networks have been proposed to solve this problem. However, none of these protocols have been designed with security in mind. If an adversary were able to compromise a node, he might prevent a network from effectively executing certain applications, such as sensing or tracking an object, or he might even disable the network by disrupting a fundamental service such as a TDMA-based channel-sharing scheme. In this paper we give a survey of the most common time synchronization protocols and outline the possible attacks on each protocol. In addition, we discuss how different sensor network applications that are affected by time synchronization attacks, and we propose some countermeasures for these attack.
Automatically Mining Result Records from Search Engine Response Pages
Authors: Dheerendranath Mundluru, Jayasimha Reddy Katukuri, Saygin Celebi
Venue: Proceedings of the Fifth IEEE International Conference on Data Mining (2005)

Usually, Web applications such as deep Web crawlers, metasearch engines, and other Web mining systems need to extract information displayed in the form of result records on response pages returned by search engines in response to submitted queries. Extracting such records is challenging as search engines are heterogeneous in displaying their records. In addition, response pages returned by many search engines include other noisy content such as advertisements, suggestion links, etc., which make the extraction task even more complicated. In this paper, we propose a highly effective and efficient algorithm for automatically mining result records from search engine response pages.
Predictive crowd simulations for Cultural Heritage applications
Authors: Diego Gutierrez, Ignacio Armenteros, Bernard Frischer
Venue: Proceedings of the 3rd international conference on Computer graphics and interactive techniques in Australasia and South East Asia (2005)

Computer technologies and digital recreations have been widely used in the field of Cultural Heritage in the past decade. However, most of the effort has concentrated in accurate data gathering and geometrical representation of buildings and sites. Only very recently, works are starting to go beyond that approach by including digital people, performing specific rites, acting as guides or merely walking around. The main goal, however, is to depart from the dead, empty reconstructions, and to try to add a new level of realism.In this paper we present our use of virtual crowds to predict behaviors in Cultural Heritage applications, hoping to help scholars draw more educated conclusions on unknown matters. The two examples we are working on at this moment are a study of the ergonomics of the Roman Colosseum and the efficiency of the Roman Senate voting system.
Interactive learning of mappings from visual percepts to actions
Authors: Sébastien Jodogne, Justus H. Piater
Venue: Proceedings of the 22nd international conference on Machine learning (2005)

We introduce flexible algorithms that can automatically learn mappings from images to actions by interacting with their environment. They work by introducing an image classifier in front of a Reinforcement Learning algorithm. The classifier partitions the visual space according to the presence or absence of highly informative local descriptors. The image classifier is incrementally refined by selecting new local descriptors when perceptual aliasing is detected. Thus, we reduce the visual input domain down to a size manageable by Reinforcement Learning, permitting us to learn direct percept-to-action mappings. Experimental results on a continuous visual navigation task illustrate the applicability of the framework.

Authors: Tobias Haist, Marcus Reicherter, Min Wu, Lars Seifert
Venue: Computing in Science and Engineering (2006)

Most people believe the most powerful integrated circuit on the personal computer (PC) is the CPU, but chances are good that they're wrong. Today's consumer graphics boards incorporate highly-integrated, parallel-working graphics processing units (GPUs) with transistor counts and performance that exceed those of CPUs.
Verifiable audit trails for a versioning file system
Authors: Randal Burns, Zachary Peterson, Giuseppe Ateniese, Stephen Bono
Venue: Proceedings of the 2005 ACM workshop on Storage security and survivability (2005)

We present constructs that create, manage, and verify digital audit trails for versioning file systems. Based upon a small amount of data published to a third party, a file system commits to a version history. At a later date, an auditor uses the published data to verify the contents of the file system at any point in time. Audit trails create an analog of the paper audit process for file data, helping to meet the requirements of electronic record legislation, such as Sarbanes-Oxley. Our techniques address the I/O and computational efficiency of generating and verifying audit trails, the aggregation of audit information in directory hierarchies, and constructing verifiable audit trails in the presence of lost data.
User-Oriented Job Management in a Grid Environment
Authors: Cuiju Luan, Guanghua Song, Yao Zheng, Guiyi Wei
Venue: Proceedings of the The Fifth International Conference on Computer and Information Technology (2005)

In a grid environment, job management is an important issue, and efforts can be made to improve its efficiency, flexibility, convenience and security. This paper presents a user-oriented job management with detailed design and implementation. The proposed job management has the advantages of reusability of job definition, flexibility and automation of file operations. The job management uses a workflow mode, that is, the whole management is divided into several separate steps. A job management wizard is designed to conduct each step. Therefore, what the grid user needs to do is to define the job by constructing necessary information at runtime. In order to save the memory and manage the jobs better, the job management adopts a two-level storage method. The first level stores the job index information, while the second keeps detailed information of the job in an XML file. Our experiments show that this approach is user friendly and job reusable.
Can coexisting overlays inadvertently step on each other?
Authors: Ram Keralapura, Chen-Nee Chuah, Nina Taft Taft, Gianluca QIannacco
Venue: Proceedings of the 13TH IEEE International Conference on Network Protocols (2005)

By allowing end hosts to make routing decisions at the application level, different overlay networks may unintentionally interfere with each other. This paper describes how multiple similar or dissimilar overlay networks making independent routing decisions could experience race conditions, resulting in oscillations in both route selection and network load. We pinpoint the causes for synchronization in terms of partially overlapping routes and periodic path probing processes and derive an analytic formulation for the synchronization probability of two overlays. Our model indicates that the probability of synchronization is non-negligible across a wide range of parameter settings, thus implying that the ill-effects of synchronization should not be ignored. Using the analytical model, we find an upper bound on the duration of traffic oscillations. We validate our model through simulations that are designed to capture the transient routing behavior of both the IP- and overlaylayers. We use our model to study the effects of factors such as path diversity (measured in round trip times) and probing aggressiveness on these race conditions. Finally, we discuss the implications of our study on the design of overlay networks and the choice of their path probing parameters.
A New Risk Management Approach Deployed over a Client/Server Distributed Functional Architecture
Authors: Victor M. Gulias, Carlos Abalde, Laura M. Castro, Carlos Varela
Venue: Proceedings of the 18th International Conference on Systems Engineering (2005)

This work shows our experience in the development of a large, scalable and reliable client/server risk management information system. It was developed using the distributed functional language. Erlang for describing the domain logic and the imperative language Java for the thin-client interface. The robust system architecture, and the extensibility and adaptability of the framework to any business model, are the main novelties of this work in the field of risk management information systems. This paper provides a semi-formal and non-technical explanation about the system intervals.
Searching for Flash Movies on the Web: A Content and Context Based Framework
Authors: Jun Yang, Qing Li, Liu Wenyin, Yueting Zhuang
Venue: World Wide Web (2005)

The phenomenal growth of online Flash movies in recent years has made Flash one of the most prevalent media formats on the Web. The retrieval and management issues of Flash, vital to the utilization of the enormous Flash resource, are unfortunately overlooked by the research community. This paper presents the first piece of work (to the best of our knowledge) in this domain by suggesting an integrated framework for the retrieval of Flash movies based on their content characteristics as well as contextual information. The proposed approach consists of two major components: (1) a content-based retrieval component, which explores the characteristics of Flash movie content at compositional and semantic levels; and (2) a context-based retrieval component, which explores the contextual information including the texts and hyperlinks surrounding the movies. An experimental Flash search engine system has been implemented to demonstrate the feasibility of the suggested framework.
Kukkia and Vilkas: Kinetic Electronic Garments
Authors: Joanna Berzowska, Marcelo Coelho
Venue: Proceedings of the Ninth IEEE International Symposium on Wearable Computers (2005)

This paper describes our first experiments in developing kinetic electronic garments, within the context of fashion and personal expression. We have integrated the shape memory alloy Nitinol in textile substrates to create Kukkia and Vilkas, two animated dresses that move or change shape over time, using resistive heating and control electronics. We describe fabrication details, including Nitinol shape setting and felting of the textile substrate. We suggest various models for programming the behavior of such an artifact, including animated, reactive, and interactive models.
UbiqStack: a taxonomy for a ubiquitous computing software stack
Authors: Martin Modahl, Bikash Agarwalla, Scott Saponas, Gregory Abowd, Umakishore Ramachandran
Venue: Personal and Ubiquitous Computing (2005)

This paper describes a taxonomy for a ubiquitous computing software stack called UbiqStack. Through the lens of the UbiqStack taxonomy we survey a variety of subsystems designed to be the building blocks from which sophisticated infrastructures for ubiquitous computing are assembled. Our experience shows that many of these building blocks fit neatly into one of the five UbiqStack categories, each containing functionally-equivalent components. Effectively identifying the best-fit &#x201c;Lego pieces&#x201d;, which in turn determines the composite functionality of the resulting infrastructure, is critical. The selection process, however, is impeded by the lack of convention for labeling these classes of building blocks. The lack of clarity with respect to what ready-made subsystems are available within each class often results in naive re-implementation of ready-made components, monolithic and clumsy implementations, and implementations that impose non-standard interfaces onto the applications above. This paper describes the UbiqStack classes of subsystems and explores each in light of the experience gained over 2&#x00a0;years of active development of both ubiquitous computing applications and software infrastructures for their deployment.
Innovative Media in Support of Distributed Intelligence and Lifelong Learning
Authors: Gerhard Fischer, Shinichi Konomi
Venue: Proceedings of the IEEE International Workshop on Wireless and Mobile Technologies in Education (2005)

Individual, unaided human abilities are constrained. Media have helped us to transcend boundaries in thinking, working, learning, and collaborating by supporting distributed intelligence. Wireless and mobile technologies provide new opportunities for empowering humans, but not without potential pitfalls. We explore these opportunities and pitfalls from a lifelong-learning perspective and discuss how wireless and mobile technologies can influence and change conceptual frameworks such as the relationship between planning and situated action, context awareness, human attention, distances in collaborative design activities, and the trade-off between tools for living and tools for learning. The impact of wireless and mobile technologies is illustrated with our research projects, which focus on moving "computing off the desktop" by "going small, large, and everywhere." Specific examples include human-centered public transportation systems, collaborative design, and information sharing with smart physical objects.
New approaches to support vector ordinal regression
Authors: Wei Chu, S. Sathiya Keerthi
Venue: Proceedings of the 22nd international conference on Machine learning (2005)

In this paper, we propose two new support vector approaches for ordinal regression, which optimize multiple thresholds to define parallel discriminant hyperplanes for the ordinal scales. Both approaches guarantee that the thresholds are properly ordered at the optimal solution. The size of these optimization problems is linear in the number of training samples. The SMO algorithm is adapted for the resulting optimization problems; it is extremely easy to implement and scales efficiently as a quadratic function of the number of examples. The results of numerical experiments on benchmark datasets verify the usefulness of these approaches.
Graphical Object Recognition using Statistical Language Models
Authors: Laura Keyes, Andrew O' Sullivan, Adam Winstanley
Venue: Proceedings of the Eighth International Conference on Document Analysis and Recognition (2005)

This paper describes a proposed system for the recognition and labeling of graphical objects within architectural and engineering documents that integrates Statistical Language Models (SLMs) with traditional classifiers. SLMs are techniques used with success in Natural Language Processing (NLP) for use in such tasks as Speech Recognition and Information Retrieval. This research proposes the adaptation of SLMs for use with graphical notation i.e. Statistical Graphical Language Model (SGLMs). Reasoning of the similarities between natural language and technical graphics is presented and the proposed use of SGLM for graphical object recognition is described.
ReachMedia: On-the-move interaction with everyday objects
Authors: Assaf Feldman, Emmanuel Munguia Tapia, Sajid Sadi, Pattie Maes, Chris Schmandt
Venue: Proceedings of the Ninth IEEE International Symposium on Wearable Computers (2005)

Mobile and wearable interfaces try to integrate digital information into our everyday experiences but usually require more attention than is appropriate and often fail to do so in a natural and socially acceptable way. In this paper we present "ReachMedia," a system for seamlessly providing just-in-time information for everyday objects, built around a wireless wristband with an RFID reader to detect objects that the user is interacting with. It enables hands and eyes free interaction with relevant information using a unique combination of audio output and gestural input, allowing socially acceptable, on-the-move interaction. This paper will focus on the general merits of the design, and the novel gesture recognition technique used, showing 95% classification rate using the realtime online classification system.
Heterogeneity-Aware Distributed Access Structure
Authors: Alejandra Gonzalez Beltran, Peter Milligan, Paul Sage
Venue: Proceedings of the Fifth IEEE International Conference on Peer-to-Peer Computing (2005)

Efficient access to distributed and dynamic multidimensional data is vital for applications in large, heterogeneous, decentralised, resource-sharing environments such as Grids and Peer-to-Peer systems. Most systems providing this functionality assume homogeneous participants. This paper proposes HADAS, an access structure exploiting heterogeneity to build a self-aware adaptive information system.
eCommerce security
Authors: Bob Gehling, David Stankard
Venue: Proceedings of the 2nd annual conference on Information security curriculum development (2005)

Internet security has become a consistent and growing problem as new Internet-based technologies and applications are developed. The number of security violation related incidents continues to increase [6]. A reported incident can be as simple as a single computer being compromised or as severe as a complete network compromise involving hundreds of client computers. All Internet content you read, send, and receive carries a risk. The amount of security risks increases at the same time that dependence on information technology grows. This demands the need for a comprehensive security program and makes the job of those persons tasked with network security even harder.
A Large Scale Distributed Platform for High Performance Computing
Authors: Nabil Abdennadher, Regis Boesch
Venue: Proceedings of the 8th International Symposium on Parallel Architectures,Algorithms and Networks (2005)

This paper describes a Global Computing (GC) environment, called XtremWeb-CH (XWCH). XWCH is an improved version of a GC tool called XtremWeb (XW). XWCH tries to enrich XW in order to match P2P concepts: distributed scheduling, distributed communication, development of symmetrical models. Two versions of XWCH were developed. The first, called XWCH-sMs, manages inter-task communications in a centralized way. The second version, called XWCH-p2p, allows a direct communication between "workers". XWCH is evaluated in the case of a real high performance genetic application.
