Automatic annotation of bibliographical references with target language
Authors: Harald Hammarström
Venue: Proceedings of the Workshop on Multi-source Multilingual Information Extraction and Summarization (2008)

In a large-scale project to list bibliographical references to all of the ca 7 000 languages of the world, the need arises to automatically annotated the bibliographical entries with ISO-639-3 language identifiers. The task can be seen as a special case of a more general Information Extraction problem: to classify short text snippets in various languages into a large number of classes. We will explore supervised and unsupervised approaches motivated by distributional characterists of the specific domain and availability of data sets. In all cases, we make use of a database with language names and identifiers. The suggested methods are rigorously evaluated on a fresh representative data set.
Queueing analysis and optimal control of BMAP/G(a,b)/1/N and BMAP/MSP(a,b)/1/N systems
Authors: A. D. Banik
Venue: Computers and Industrial Engineering (2009)

We first consider a finite-buffer single server queue where arrivals occur according to batch Markovian arrival process (BMAP). The server serves customers in batches of maximum size 'b' with a minimum threshold size 'a'. The service time of each batch follows general distribution independent of each other as well as the arrival process. We obtain queue length distributions at various epochs such as, pre-arrival, arbitrary, departure, etc. Some important performance measures, like mean queue length, mean waiting time, probability of blocking, etc. have been obtained. Total expected cost function per unit time is also derived to determine the optimal value N^* of N at a minimum cost for given values of a and b. Secondly, we consider a finite-buffer single server queue where arrivals occur according to BMAP and service process in this case follows a non-renewal one, namely, Markovian service process (MSP). Server serves customers according to general bulk service rule as described above. We derive queue length distributions and important performance measures as above. Such queueing systems find applications in the performance analysis of communication, manufacturing and transportation systems.
On the evaluation of dynamic critiquing: a large-scale user study
Authors: Kevin McCarthy, Lorraine McGinty, Barry Smyth, James Reilly
Venue: Proceedings of the 20th national conference on Artificial intelligence - Volume 2 (2005)

Critiquing is an important form of feedback in conversational recommender systems. However, in these systems the user is usually limited to critiquing a single product feature at a time. Recently dynamic critiquing has been proposed to address this shortcoming, by automatically generating compound critiques over multiple features that may be presented to the user at recommendation time. To date a number of different versions of dynamic critiquing have been evaluated in isolation, and with reference to artificial users. In this paper we bring together the main flavors of dynamic critiquing and perform a large-scale comparative evaluation as part of an extensive real-user trial. This evaluation reveals some interesting facts about the way real users interact with critique-based recommenders.
Evaluation of Gaussian Linear Model Order Selection Approaches
Authors: Yu-Ming Du, Xiao-dan Du, Fu-gui Zhang
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

Model order selection approaches are usually evaluated in simulations by comparing the resulting model orders to the true model order. In this paper, the mean Kullback-Leibler divergence (MKD) between the selected model and the true model is proposed as an objective measure for evaluating different model order selection approaches in simulations. For Gaussian linear model order selection problems the Kullback-Leibler divergence are reduced to simple forms and the MKD can be easily computed. Simulation results show that the MKD is a reasonable measure to evaluate different Gaussian Linear model order selection approaches, in terms of signal processing.
Word lookup on the basis of associations: from an idea to a roadmap
Authors: Michael Zock, Slaven Bilac
Venue: Proceedings of the Workshop on Enhancing and Using Electronic Dictionaries (2004)

Word access is an obligatory step in language production. In order to achieve his communicative goal, a speaker/writer needs not only to have something to say, he must also find the corresponding word(s). Yet, knowing a word, i.e. having it stored in a data-base or memory (human mind or electronic device) does not imply that one is able to access it in time. This is a clearly a case where computers (electronic dictionaries) can be of great help. In this paper we present our ideas of how an enhanced electronic dictionary can help people to find the word they are looking for. The yet-to-be-built resource is based on the age-old notion of association: every idea, concept or word is connected. In other words, we assume that people have a highly connected conceptuallexical network in their mind. Finding a word amounts thus to entering the network at any point by giving the word or concept coming to their mind (source word) and then following the links (associations) leading to the word they are looking for(target word). Obviously, in order to allow for this kind of access, the resource has to be built accordingly. This requires at least two things: (a) indexing words by the associations they evoke, (b) identification and labeling of the most frequent/useful associations. This is precisely our goal. Actually, we propose to build an associative network by enriching an existing electronic dictionary (essentially) with (syntagmatic) associations coming from a corpus, representing the average citizen's shared, basic knowledge of the world (encyclopedia). Such an enhanced electronic database resembles in many respects our mental dictionary. Combining the power of computers and the flexibility of the human mind (omnidirectional navigation and quick jumps), it emulates to some extent the latter in its capacity to navigate quickly and efficiently in a large data base. While the notions of association and spreading activation are fairly old, their use to support word access via computer is new. The resource still needs to be built, and this is not a trivial task. We discuss here some of the strategies and problems involved in accomplishing it with the help of people and computers (automation).
The XML-Based Information Sharing Technology for the Power Enterprise
Authors: Zhang Lijing, Wang Da, Pan Weihua
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 03 (2009)

In order to solve the current power enterprise information sharing problems and based on the describing the traditional forms of data transfers, We propose an advanced XML-based model which can solve the information sharing problems of heterogeneous databases. It will inquiry firstly and integrate the data next. This system is mainly used for power enterprise applications. Users can query the heterogeneous database in the model of B/S without caring the storage format of the data. At the same time, the conversion between the resources of database and the XML and the integration of the resources provide a new idea for the sharing of heterogeneous data sources, applications and release, which is a better technical solution of the heterogeneous data sharing between the internal of the enterprise and other enterprises.
Perspectives on Transactional Memory
Authors: Martín Abadi, Tim Harris
Venue: Proceedings of the 20th International Conference on Concurrency Theory (2009)

We examine the role of transactional memory from two perspectives: that of a programming language with atomic actions and that of implementations of the language. We argue that it is difficult to formulate a clean, separate, and generally useful definition of transactional memory. In both programming-language semantics and implementations, the treatment of atomic actions benefits from being combined with that of other language features. In this respect (as in many others), transactional memory is analogous to garbage collection, which is often coupled with other parts of language runtime systems.

Authors: Hongyou Li, Xiaomei Liu, Yinbiao Guo, Chen Jiang, Hui Wang
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

Pulse electrochemical surface finishing is an anodic dissolution process of metal as anode ion by ion, easily realizes surface finishing. Because of using high frequency short pulse current, the flowing field, electrical field and electrochemical behavior inside the inter-electrode gap have been improved obviously. So it can use less inter-electrode gap, and finally leads to improving surface finishing quality, efficiency and ensuring machining accuracy. Another interesting aspect of it is the availability of several electrical parameters such as pulse current density, pulse time, and duty cycle for process optimization. In this paper, Pulse electrochemical finishing (PECF) and pulse electrochemical compound finishing (PECCF) are introduced.The main technical parameters, including in inter-electrode gap, current density, compositions of steel materials and pulse parameters on the resulting surface finish were investigated. PECF and PECCF on different surface including plane and shaft's surface are introduced. Well-pleasing experimental results is gained.
3D Visualization of Medical Image Data Employing 2D Histograms
Authors: Stefan Wesarg, Matthias Kirschner
Venue: Proceedings of the 2009 Second International Conference in Visualisation (2009)

Transfer functions (TF) are a means for improving the visualization of 3D medical image data. If in addition to intensity another property is employed, two-dimensional TFs can be specified. For this, 2D histograms are helpful. In this work we investigate how the property feature size can be used for the definition of 2D TFs and the visualization of medical image data. Furthermore, we compare this method to approaches that employ gradient magnitude as second property. From our experiments with several medical image data we conclude, that structure size enhanced 2D histograms are more intuitive. This is especially true in the clinical area, where physicians are much more familiar with the meaning of the size of anatomical structures than with the concept of gradient magnitude.
Metadata-Driven SOA-Based Application for Facilitation of Real-Time Data Warehousing
Authors: Damir Pintar, Mihaela Vranić, Zoran Skočir
Venue: Proceedings of the 10th International Conference on E-Commerce and Web Technologies (2009)

Service-oriented architecture (SOA) has already been widely recognized as an effective paradigm for achieving integration of diverse information systems. SOA-based applications can cross boundaries of platforms, operation systems and proprietary data standards, commonly through the usage of Web Services technology. On the other side, metadata is also commonly referred to as a potential integration tool given the fact that standardized metadata objects can provide useful information about specifics of unknown information systems with which one has interest in communicating with, using an approach commonly called "model-based integration". This paper presents the result of research regarding possible synergy between those two integration facilitators. This is accomplished with a vertical example of a metadata-driven SOA-based business process that provides ETL (Extraction, Transformation and Loading) and metadata services to a data warehousing system in need of a real-time ETL support.
A logic of agent programs
Authors: N. Alechina, M. Dastani, B. S. Logan, J.-J. Ch. Meyer
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 1 (2007)

We present a sound and complete logic for reasoning about Simple APL programs. Simple APL is a fragment of the agent programming language 3APL designed for the implementation of cognitive agents with beliefs, goals and plans. Our logic is a variant of PDL, and allows the specification of safety and liveness properties of agent programs. We prove a correspondence between the operational semantics of Simple APL and the models of the logic for two example program execution strategies. We show how to translate agent programs written in SimpleAPL into expressions of the logic, and give an example in which we show how to verify correctness properties for a simple agent program.
Study on Association Rules Mining Based on Searching Frequent Free Item Sets Using Partition
Authors: Zhang Hui, Lu Yu, Zhou Jinshu
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 01 (2009)

Mining of association rules is an important problem in data mining, given a large set of data, extracting frequent item sets in this set is a challenging job in data mining. Item sets matching is the chief problem in extracting frequent item sets. And item set matching is the bottleneck of the mining process. It also has been proved that extracting frequent free item sets is a useful method. Many efficient algorithms have been proposed in the literature. The idea presented in this paper is to divide the database into multiple partitions and then find frequent free item sets in each partition, then merge the several partitions to generate other frequent free item sets and count the support. The algorithm costs little memory to save additional support numbers of item sets in each partition but greatly reduces the time of item set matching which is the bottleneck of the mining process. The experiments on real datasets have showed its good performance.
Populating a domain ontology from web historical dictionaries and encyclopedias
Authors: Eduardo Motta, Alexandre Andreatta, Sean Siqueira
Venue: Proceedings of the 2008 Euro American Conference on Telematics and Information Systems (2008)

An increasing volume of information is available on the web and usually is expressed as text, representing unstructured or semi-structured data. Thus, semantic information is implicit in these texts, since they are mainly intended for human consumption and interpretation. Therefore, it is not easy to automatically identify concepts or establish relations among them inside the texts. In particular, some web sites contain information on historical data about artistic manifestations like literature or music. This kind of site contains a body of knowledge on the domain, and usually is constructed with some format and content patterns that may be useful for information extraction. In order to make this information available as a structured knowledge base, an information extraction process is necessary. Ontologies are an appropriate way to represent structured knowledge bases, enabling sharing, reuse and inference. In this paper, it is described an information extraction process cycle for populating a domain ontology using texts available on the internet to extract instances of concepts, events and relations, based on existing ontology development methodologies and information extraction techniques. Through this process, latent concepts and relations expressed in natural language can be extracted and represented as an ontology, allowing new uses of the available content. A case study that applies this process is presented.
Piezocomposite SmartFoam for Active Control of Underwater Noise
Authors: Tang Jun, Wang Tongqing
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 02 (2009)

A study on smart foam for passive–active underwater sound reduction in sound pulse tube is presented. The smart foam consists of cylindrically curved sections of PVDF film embedded in polyurethane acoustic foam forming a thin, compact arrangement. The device is designed to reduce sound by the simultaneous action of the passive absorption of the foam (effective at high frequencies) and the active input of the PVDF element driven by an oscillating electrical input(effective at low frequencies). A digital time delay & feed-forward control system has been developed and severs for the smart foam control system. The concept of smart foam control system is that of an open-loop velocity feedback between sensors and actuator.
From e3-value to REA: Modeling Multi-party E-business Collaborations
Authors: Rainer Schuster, Thomas Motal
Venue: Proceedings of the 2009 IEEE Conference on Commerce and Enterprise Computing (2009)

In order to open-up enterprise applications to e-businessand make them profitable for a communication with otherenterprise applications, a business model is needed showingthe business essentials of the e-commerce business caseto be developed. Currently there are two major businessmodeling techniques - e3-value and REA (Resource-Event-Agent). Whereas e3-value was designed for modeling valueexchanges within an e-business network of multiple businesspartners, the REA ontology assumes that, in the presence ofmoney and available prices, all multi-party collaborationsmay be decomposed into a set of corresponding binarycollaborations. This paper is a preliminary attempt to viewe3-value and REA used side-by-side to see where they cancomplement each other in coordinated use in the context ofmultiple-partner collaboration. A real life scenario from theprint media domain has been taken to proof our approach.
Exploring the effectiveness of an idea-centered design to foster a computer-supported knowledge building environment
Authors: Huang-Yao Hong, Fei-Ching Chen, Hsiu-Mei Chang, Calvin C. Y. Liao, Wen-Ching Chan
Venue: Proceedings of the 9th international conference on Computer supported collaborative learning - Volume 1 (2009)

This paper compares the effectiveness of two multimedia environments-- Blackboard Learning System™ and Knowledge Forum™--in terms of their underlying design approaches to support collaborative learning and knowledge work. The two design approaches are (1) a conventional theme-based approach, i.e., to center group collaboration and meaning interaction around themes, and (2) an idea-centered approach, i.e., to center group collaboration and meaning interaction around sustained idea exchange and improvement. Findings suggest that an idea-centered design approach seems more likely to construct an environment that fosters more dynamic group and meaning interactions, thus enabling more sustained collaborative learning and knowledge building.
An Approach to Integrating the User Credit Values on Multiple E-Commerce Websites
Authors: Xiao Wei, Shunxiang Zhang
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 01 (2009)

Credit values are regarded as an important factor in E-commerce trades by both buyer and seller, so they look forward to increasing their credit values. A feasible approach is to gather the credit values distributed in different E-commerce websites. But the protection policies of E-commerce websites result in the difficulty in realizing the integration of credit values in terms of policy and technology. An approach to integrating credit values is put forward and the solutions to several key technical problems of the integration process are presented in this paper. This approach is proved to be feasible and it will be of value to the network applications.

Authors: Shiliang Su, Xia Chen, Jiaping Wu, Xiaoya Ma
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 01 (2009)

An integrative fuzzy set pair model, established by integrating fuzzy assessment and set pair analysis, was introduced to assess the land ecological security states. The approximate degree of land ecological security to the optimal standard set was calculated to describe the security level by combining multiple indices. The indices and weights were determined by Delphi and fuzzy AHP (Analytic Hierarchy Process) respectively. The model was validated and applied to the case study of Xiaolangdi Reservoir regions.
A New Adaptive Flow Control for Mesh-based Network-on-Chip (NoC)
Authors: Minghua Tang, Xiaola Lin
Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

The rate of injecting packets into the network should be regulated carefully because the packet latency could increase rapidly if the network saturated. In order to solute this problem, we present a new flow control strategy which can be coupled with any routing algorithm. In particular, we introduce the notion of Injection Level, a set of values of injection rate. We expect to simplify the process of flow control by applying a group of predefined injection rates according to the status of the network. The performance of the strategy is evaluated by a flit-accurate and opensource simulator. Results show that the NoC could avoid the saturation problem successfully.

Authors: Jennifer Cloud-Buckner, Michael Sellick, Bhanuteja Sainathuni, Betty Yang, Jennie Gallimore
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part III: Ubiquitous and Intelligent Interaction (2009)

Avatars and virtual agents are used in social, military, educational, medical, training, and other applications. Although there is a need to develop avatars with human-like characteristics, many applications include avatars based on stereotypes. Prabhala and Gallimore (2007) conducted research to develop collaborative computer agents with personality. Using the Big Five Factor Model of personality they investigated how people perceive personality based on actions, language, and behaviors of two voice-only computer agents in a simulation. However, these computer agents included no visual features in order to avoid stereotypes. The objective of the current research extends the work of Prabhala and Gallimore by investigating the effects of personality, race, and gender on perceived personality of avatars with animated faces. Results showed that subjects were able to distinguish the different personalities and race and gender significantly affected perceptions on a trait-by-trait basis.
