Domain adaptation with artificial data for semantic parsing of speech
Authors: Lonneke van der Plas, James Henderson, Paola Merlo
Venue: Proceedings of Human Language Technologies: The 2009 Annual Conference of the North American Chapter of the Association for Computational Linguistics, Companion Volume: Short Papers (2009)

We adapt a semantic role parser to the domain of goal-directed speech by creating an artificial treebank from an existing text tree-bank. We use a three-component model that includes distributional models from both target and source domains. We show that we improve the parser's performance on utterances collected from human-machine dialogues by training on the artificially created data without loss of performance on the text treebank.

Authors: Zhou Zhi-min, Zhang Yuan-liang, Li Xiao-yan, Hong Shao-jun, Xia Zhi-hui
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 03 (2009)

Interference will possibly happen between the tools and the surfaces to be machined while cutting the unitary wave-front correctors with single linear blade diamond tools. According to the mathematic model of the work piece surface and the tool path, the mathematical model is established to show the minimum setting angle while there is no interference between the tools and the surfaces to be machined. Also, the maximum setting angle meeting the ordered surface roughness is deduced based on the relationship between the microcosmic unevenness height of optical surfaces and the parameters of cutting edges and the setting angle. Practical cutting experiments are performed on an ultra-precision lathe. The results of experiments indicate that it is feasible to machine unitary wave-front correctors by linear blade nature diamond tool. The mathematics model of the minimum setting angle between the linear blade diamond tool and work piece's surface is practical when machining unitary wave-front correctors

Authors: Manami Saito, Kazuhide Yamamoto, Satoshi Sekine
Venue: Proceedings of the Human Language Technology Conference of the NAACL, Companion Volume: Short Papers on XX (2006)

This paper describes a system which identifies discourse relations between two successive sentences in Japanese. On top of the lexical information previously proposed, we used phrasal pattern information. Adding phrasal information improves the system's accuracy 12%, from 53% to 65%.
Computational intelligence tools for next generation quality of service management
Authors: Rafael del-Hoyo, Bonifacio Martín-del-Brío, Nicolas Medrano, Julian Fernández-Navajas
Venue: Neurocomputing (2009)

In this paper we explore the interest of computational intelligence tools in the management of heterogeneous communication networks, specifically to predict congestion, failures and other anomalies in the network that may eventually lead to degradation of the quality of offered services. We show two different applications based on neural and neuro-fuzzy systems for quality of service (QoS) management in next generation networks for voice and video service over heterogeneous Internet protocol (V2oIP) services. The two examples explained in this paper attempt to predict the communication network resources for new incoming calls, and visualizing the QoS of a communication network by means of self-organizing maps.
An agent-based system approach to fixture design
Authors: Sertac Pehlivan, Joshua D. Summers, Farhad Ameri
Venue: International Journal of Computer Applications in Technology (2009)

The development of an integrated computer-aided fixture design (CAFD) environment is heavily influenced by system architecture. Many of the architectures that have been employed in developing CAFD tools have followed a traditional or a concurrent engineering design process model, driven by the traditional notions of systematic fixture design. This paper takes a new approach by exploring the fundamental differences between various distributed design architectures, with the goal of matching the requirements for an extendable CAFD environment capitalising on the strengths of various system architecture templates to support the requisites of fixture design information support. Ultimately, an architecture is proposed and illustrated through a case study.
Engineering of Services and Business Models for Grid Applications
Authors: Jürgen Falkner, Anette Weisbecker
Venue: Proceedings of the 6th International Workshop on Grid Economics and Business Models (2009)

In the context of using grid applications in medicine and bioinformatics a combination of classic biomedical services like the analysis of biomaterial with grid services is quite common. Services for customers in those fields need to comprise both and offer an easy way to use these combined services. Within the German project Services@MediGRID, methods for the systematic development of complex customer services including the use of grid applications are developed. In coordination with this service engineering approach for grid applications, commercial business models are derived for a set of biomedical grid services.
Customizable Visualization of Multi-omics Data in the Context of Biochemical Networks
Authors: Peter Droste, Stephan Noack, Katharina Noh, Wolfgang Wiechert
Venue: Proceedings of the 2009 Second International Conference in Visualisation (2009)

This contribution presents a novel approach of visualization in the context of biochemical networks. In this field of application, simulation and experimental studies continuously produce a wide variety of data with a direct relation to nodes and edges of the networks. This leads to an urgent requirement of a data visualization method which is flexible and adaptable to many applications. The visualization software tool presented here allows creating network diagrams with a programmable style of network components. This was realized by defining the scripting language OVL in order to give a fast and intuitive access to visual properties of nodes and edges. Additionally, networks can be displayed in different abstraction levels. So, data visualization becomes highly customizable to individual requirements and preferences.
Some Interpretative Tools for Non-Symmetrical Correspondence Analysis
Authors: Eric J. Beh, Luigi D'Ambra
Venue: Journal of Classification (2009)

Non-symmetrical correspondence analysis (NSCA) is a very practical statistical technique for the identification of the structure of association between asymmetrically related categorical variables forming a contingency table. This paper considers some tools that can be used to numerically and graphically explore in detail the association between these variables and include the use of confidence regions, the establishment of the link between NSCA and the analysis of variance of categorical variables, and the effect of imposing linear constraints on a variable.
Integrated Representation and Visualisation of the Dynamics in Computer-mediated Social Networks
Authors: Andreas Harrer, Sam Zeini, Sabrina Ziebarth
Venue: Proceedings of the 2009 International Conference on Advances in Social Network Analysis and Mining (2009)

In this paper we will demonstrate the potential of processing and visualising the dynamics of computer-mediated communities by means of Social Network Analysis. According to the fact that computer-mediated community systems are manifested also as structured data, we use data structures like e-mail, discussion boards, and bibliography sources for an automatic transformation into social network data formats. Currently our developed converter DMD (Data Multiplexer Demultiplexer) supports GraphML, UCINET, and Pajek formats besides our own data formats which are used for real-time analysis of CSCL (Computer Supported Collaborative Learning) activities. In the case of communication data our converters utilize conversation graphs reflecting aspects of speech act and conversational theory to produce directed graphs in the cases where one-mode person networks are desired. The paper will demonstrate a 3-dimensional visualisation of an author community based on Bibtex bibliography data converted into GraphML. Based on this dataset we visualise publications network with a tool called Weaver, which is developed in our research group. According to Lothar Krempel’s algorithm, Weaver uses the first two dimensions to embed the network structure within a common solution space. The third dimension is used for representing the time axis and thus the dynamics of co-authorship relations.Concluding we aim to discuss potential issues and problems of our approach and the possibilities especially concerning the appropriate visualisation and segmentation of long term communications, such as mailing lists.
Coordinating Heterogeneous Game-Based Learning Approaches in Online Learning Environments
Authors: Javier Torrente, Pablo Lavín Mera, Pablo Moreno-Ger, Baltasar Fernández-Manjón
Venue: Transactions on Edutainment II (2009)

Game-based learning is quickly becoming a popular trend in Technology-Enhanced Learning. However, the field is very broad with many different initiatives being classified as game-based learning. On the other hand, instructors are demanding effective ways to track the interaction of the students with the games and to assess the learning process. The diversity is a major issue in this regard, requiring instructors to understand each game and to evaluate different kinds of games in different ways. In this work we present a unified mechanism to gather tracking and assessment information from different and varied games. All the information is stored in an online learning environment, where the instructor can consult it. The keystone of the approach is a tracking and assessment API that can be implemented by different games on the client-side and by diverse online learning environments on the server-side. This approach is illustrated with the <e-Adventure> family of educational platforms, which support this interoperable API.
Videogames in Computer Space: The Complex History of Pong
Authors: Henry Lowood
Venue: IEEE Annals of the History of Computing (2009)

The earliest digital games emerged out of laboratories and research centers in the 1960s and 1970s. The intertwined histories of Nolan Bushnell's Computer Space and Pong illustrate the transition from these "university games" to accessible entertainment and educational games as well as the complicated historical relationship among the arcade, computer, and videogames.
Logical Foundations for Similarity-Based Databases

Venue: Database Systems for Advanced Applications: DASFAA 2009 International Workshops: BenchmarX, MCIS, WDPP, PPDA, MBC, PhD, Brisbane, Australia, April 20 - 23, 2009 (2009)

Extensions of relational databases which aim at utilizing various aspects of similarity and imprecision in data processing are widespread in the literature. A need for development of solid foundations for such extensions, sometimes called similarity-based relational databases, has repeatedly been emphasized by leading database experts. This paper argues that, contrary to what may be perceived from the literature, solid foundations for similarity-based databases can be developed in a conceptually simple way. In this paper, we outline such foundations and develop in detail a part of the the facet related to similarity-based queries and relational algebra. The foundations are close in principle to Codd's foundations for relational databases, yet they account for the main aspects of similarity-based data manipulation. A major implication of the paper is that similarity-based data manipulation can be made an integral part of an extended, similarity-based, relational model of data, rather than glued atop the classic relational model in an ad hoc manner.
An Overview of Prophet
Authors: Zheng Chen, Yin-Liang Zhao, Xiao-Yu Pan, Zhao-Yu Dong, Bing Gao, Zhi-Wen Zhong
Venue: Proceedings of the 9th International Conference on Algorithms and Architectures for Parallel Processing (2009)

Speculative Multithreading (SpMT) has been proposed as a perspective method to exploit Chip Multiprocessors (CMP) hardware potential. This paper researches speculative thread-level parallelism(TLP) for general-purpose programs. The Prophet system consists of a SpMT compiler framework and a simulator prototype based on the SpMT execution model. In the Prophet system, procedures are represented as weighted control flow graph (WCFG), the thread generator uses structural analysis and heuristic algorithm to partition the WCFG into sub-graphs which represent the candidate threads. Inter-thread data dependences are predicted by pre-computation slice (p-slice) to reduce RAW violation. Since the partition is speculative, thread state control mechanism and multi-versioning cache system are designed to buffer the speculative data, and a snooping bus based cache coherence protocol is used to detect data dependence violation. Simulation-based evaluation shows that the Prophet system could achieve significant speedup for general-purpose programs.
Implementation of a Non-bonded Interaction Calculation Algorithm for the Cell Architecture
Authors: Eduard Fomin, Nikolay Alemasov
Venue: Proceedings of the 10th International Conference on Parallel Computing Technologies (2009)

Calculation of non-bonded interactions takes up to 80% of the total execution time of a molecular dynamics program. It can be accelerated by porting the algorithm to the Cell architecture. A simple method of such porting has been applied to the MOLKERN program, which simulates the structure and dynamics of biomolecular models. A 32-fold speedup was achieved for calculation of short-range non-bonded interactions, and threefold, for long-range Coulomb interactions. The overall program speedup proved to be more than 4.

Living cells possess properties that enable them to withstand the physiological environment as well as mechanical stimuli occurring within and outside the body. Any deviation from these properties will undermine the physical integrity of the cells as well as their biological functions. Thus, a quantitative study in single cell mechanics needs to be conducted. In this paper we will examine fluid flow and Neo-Hookean deformation. Particularly, a mechanical model to describe the cellular adhesion with detachment is proposed. Restricting the interest on the contact surface and elaborating again the computational results, it is possible to develop our idea about to reproduce the phases coexistence in the adhesion strip. Subsequently, a number of simulations have been carried out, involving a number of human cells with different mechanical properties. All the collected data have been used in order to train and test a suitable Artificial Neural Network (ANN) in order to classify the kind of cell. Obtained results assure good performances of the implemented classifier, with very interesting applications.
Virtual Agents and 3D Virtual Worlds for Preserving and Simulating Cultures
Authors: Anton Bogdanovych, Juan Antonio Rodriguez, Simeon Simoff, Alex Cohen
Venue: Proceedings of the 9th International Conference on Intelligent Virtual Agents (2009)

Many researchers associate a culture with some form of knowledge; other scholars stress the importance of the environment inhabited by the knowledge carriers; while archaeologists learn about cultures through the objects produced in the environment as a result of utilizing this knowledge. In our work we propose a model of virtual culture that preserves the environment, objects and knowledge associated with a certain culture in a 3D Virtual World. We highlight the significance of virtual agents in our model as, on the one hand, being the knowledge carriers and, on the other hand, being an important element establishing the connection between the environment, objects and knowledge. For testing the resulting model we have developed a research prototype simulating the culture of the ancient City of Uruk 3000 B. C. (one of the first human-built cities on Earth) within a Virtual World of Second Life.
The reliability of anaphoric annotation, reconsidered: taking ambiguity into account

Venue: Proceedings of the Workshop on Frontiers in Corpus Annotations II: Pie in the Sky (2005)

We report the results of a study of the reliability of anaphoric annotation which (i) involved a substantial number of naive subjects, (ii) used Krippendorff's &alpha; instead of K to measure agreement, as recently proposed by Passonneau, and (iii) allowed annotators to mark anaphoric expressions as ambiguous.
Modeling covariance matrices via partial autocorrelations
Authors: M. J. Daniels, M. Pourahmadi
Venue: Journal of Multivariate Analysis (2009)

We study the role of partial autocorrelations in the reparameterization and parsimonious modeling of a covariance matrix. The work is motivated by and tries to mimic the phenomenal success of the partial autocorrelations function (PACF) in model formulation, removing the positive-definiteness constraint on the autocorrelation function of a stationary time series and in reparameterizing the stationarity-invertibility domain of ARMA models. It turns out that once an order is fixed among the variables of a general random vector, then the above properties continue to hold and follow from establishing a one-to-one correspondence between a correlation matrix and its associated matrix of partial autocorrelations. Connections between the latter and the parameters of the modified Cholesky decomposition of a covariance matrix are discussed. Graphical tools similar to partial correlograms for model formulation and various priors based on the partial autocorrelations are proposed. We develop frequentist/Bayesian procedures for modelling correlation matrices, illustrate them using a real dataset, and explore their properties via simulations.

A combinatorial approach to involution and &#x03b4;-regularity I: involutive bases in polynomial algebras of solvable type
Authors: Werner M. Seiler
Venue: Applicable Algebra in Engineering, Communication and Computing (2009)

Involutive bases are a special form of non-reduced Gr&#x00f6;bner bases with additional combinatorial properties. Their origin lies in the Janet&#x2013;Riquier theory of linear systems of partial differential equations. We study them for a rather general class of polynomial algebras including also non-commutative algebras like those generated by linear differential and difference operators or universal enveloping algebras of (finite-dimensional) Lie algebras. We review their basic properties using the novel concept of a weak involutive basis and present concrete algorithms for their construction. As new original results, we develop a theory for involutive bases with respect to semigroup orders (as they appear in local computations) and over coefficient rings, respectively. In both cases it turns out that generally only weak involutive bases exist. The ACM Portal is published by the Association for Computing Machinery. Copyright © 2010 ACM, Inc.

Implementation of a Performance-Based Loop Scheduling on Heterogeneous Clusters
Authors: Chao-Tung Yang, Lung-Hsing Cheng
Venue: Proceedings of the 9th International Conference on Algorithms and Architectures for Parallel Processing (2009)

Cluster computing systems usually connect several commodity computers in local-area networks to form a single, unified resource for parallel computing. Loop scheduling and load balancing on parallel and distributed systems are critical problems that are difficult to cope with, especially on the emerging heterogeneous clusters. In this aspect, an important issue is how to assign tasks to nodes so that the nodes' loads are well balanced. In this paper, we propose a performance-based approach that partitions loop iterations according to the performance weighting of cluster nodes. A heterogeneous cluster was built to verify the proposed approach, and two kinds of application program were implemented for execution on this testbed. Experimental results show that the proposed approach performs better than previous schemes.
The category of double fuzzy preproximity spaces
Authors: A. M. Zahran, M. Azab Abd-Allah, Kamal El-Saady, A. Ghareeb
Venue: Computers Mathematics with Applications (2009)

In this paper, we introduce the notions of double neighborhood systems and double fuzzy preproximity in double fuzzy topological spaces. We used double neighborhoods to study the initial structure of double fuzzy topological spaces, and the joins between them and the initial structures of double fuzzy preproximity spaces. Furthermore, we have proved that the category of double fuzzy preproximity spaces is a topological category, and hence a topological construct.
