Co-WEB: A Peer-to-Peer Based, Partially Decentralized Framework for Collaborative Web-Content Publishing
Authors: Rashid Turgunbaev, Hideyuki Takada
Venue: Proceedings of the 2009 First International Conference on Advances in Future Internet (2009)

Web-content publishing is a service that is mainly provided by traditional client-server architecture. However, traditional approach requires much computer and network resources and therefore is relatively expensive. There are methods to publish web-content directly from users own computers. But in these approaches users have to keep their computers switched on continuously to publish for 24 hours. This paper describes a partially decentralized, collaborative web-content publishing system which allows organize 24 hours web-content publishing directly from web-publishers’ own computers without a change in their computers’ usual operating time. To reach 24 hours publishing time web-publishers, usually with several hours uptime period, will organize groups which will include web-publishers with different uptime ranges (e.g. from different time zones or with different life styles) to cover each others’ downtime periods. Inside a group web-publishers will synchronize their contents with each other and then, take turns in publishing group’s contents while they are on-line. We provide experiment results that show feasibility of organizing 24 hours publishing time with several hours uptime period and also give resource consumption comparison results.
Emotional factors influencing technology acceptance particularly with regard to mobile service usage
Authors: Elisabeth Platzer
Venue: Proceedings of the 11th International Conference on Human-Computer Interaction with Mobile Devices and Services (2009)

In December 2008 the 4 billion mark of mobile phone subscribers has been passed. All these people use their mobile phones in different ways and with varying objectives often guided or influenced by their emotions. Substantial profits are no longer gained with standard services like voice calls or SMS but with data services (e.g. Mobile TV or Location based services). Lots of these services are not initially successful even though their high level of usability was pre-estimated by means of traditional test procedures. Hence there is a huge demand for a method to examine individuals' adoption and usage decisions that provides acceptance explanations that are valid regarding reality not only statistics.

Authors: Chin-Teng Lin, Li-Wei Ko, Che-Jui Chang, Yu-Te Wang, Chia-Hsin Chung, Fu-Shu Yang, Jeng-Ren Duann, Tzyy-Ping Jung, Jin-Chern Chiou
Venue: Proceedings of the 5th International Conference on Foundations of Augmented Cognition. Neuroergonomics and Operational Neuroscience: Held as Part of HCI International 2009 (2009)

This study extends our previous work on mobile wireless EEG acquisition to a truly wearable and wireless human-machine interface, NCTU Brain-Computer-Interface-headband (BCI-headband), featuring: (1) dry Micro-Electro-Mechanical System (MEMS) EEG electrodes with 400 ganged contacts for acquiring signals from non-hairy sites without use of gel or skin preparation; (2) a miniature data acquisition circuitry; (3) wireless telemetry; and (4) online signal processing on a commercially available cell phone or a lightweight, wearable digital signal processing module. The applicability of the NCTU BCI-headband to EEG monitoring in real-world environments was demonstrated in a sample study: cognitive-state monitoring and management of participants performing normal tasks.
Texture Retrieval by Scale and Rotation Invariant Directional Empirical Mode Decomposition
Authors: Mingliang Hou, CunHua Li, Yong Zhang
Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

In this paper, a method fortexture retrieval based on Scale and Rotation Invariant Directional Empirical Mode Decomposition (SRIDEMD) is presented. Different from other filtering based techniques such as wavelet and Gabor decomposition, EMD uses the nonlinear filtering process called 'sifting' which attains its scalead aptivity and obtained Intrinsic Mode Functions (IMFs) which has approximate orthogonality. We extend DEMD which is a fast technique of extending 1-D EMD to 2-D case by introducing scale and rotation invariance. Features including frequency and envelopes of IMFs are extracted after 2-D Hilbert transform. Decomposition in several directions is made for rotation invariance and main direction is used. Scale-invariant features are attained by further processing the results and using fractal dimensions of the residues and IMFs. We validate the effectiveness of this method by experiments for textures from public texture database.
GRIN: a graph based RDF index
Authors: Octavian Udrea, Andrea Pugliese, V. S. Subrahmanian
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 2 (2007)

RDF ("Resource Description Framework") is now a widely used World Wide Web Consortium standard. However, methods to index large volumes of RDF data are still in their infancy. In this paper, we focus on providing a very lightweight indexing mechanism for certain kinds of RDF queries, namely graph-based queries where there is a need to traverse edges in the graph determined by an RDF database. Our approach uses the idea of drawing circles around selected "center" vertices in the graph where the circle would encompass those vertices in the graph that are within a given distance of the "center" vertex. We come up with methods of finding such "center" vertices and identifying the radius of the circles and then leverage this to build an index called GRIN. We compare GRIN with three existing RDF indexex: Jena, Sesame. and RDFBroker. We compared (i) the time to answer graph based queries, (ii) memory needed to store the index, and (iii) the time to build the index. GRIN outperforms Jena, Sesame and RDFBroker on all three measures for graph based queries (for other types of queries, it may be worth building one of these other indexes and using it), at the expense of using a larger amount of memory when answering queries.
Temporal classification of text and automatic document dating
Authors: Angelo Dalli
Venue: Proceedings of the Human Language Technology Conference of the NAACL, Companion Volume: Short Papers on XX (2006)

Temporal information is presently underutilised for document and text processing purposes. This work presents an unsupervised method of extracting periodicity information from text, enabling time series creation and filtering to be used in the creation of sophisticated language models that can discern between repetitive trends and non-repetitive writing pat-terns. The algorithm performs in O(n log n) time for input of length n. The temporal language model is used to create rules based on temporal-word associations inferred from the time series. The rules are used to automatically guess at likely document creation dates, based on the assumption that natural languages have unique signatures of changing word distributions over time. Experimental results on news items spanning a nine year period show that the proposed method and algorithms are accurate in discovering periodicity patterns and in dating documents automatically solely from their content.
On the Dependencies between Internet Flow Characteristics
Authors: M. Rosário Oliveira, António Pacheco, Cláudia Pascoal, Rui Valadas, Paulo Salvador
Venue: Traffic Management and Traffic Engineering for the Future Internet: First Euro-NF Workshop, FITraMEn 2008, Porto, Portugal, December 11-12, Revised Selected Papers (2009)

The development of realistic Internet traffic models of applications and services calls for a good understanding of the nature of Internet flows, which can be affected by many factors. Especially relevant among these are the limitations imposed by link capacities and router algorithms that control bandwidth on a per-flow basis. In the paper, we perform a statistical analysis of an Internet traffic trace that specifically takes into account the upper-bounds on the duration and rate of measured flows. In particular, we propose a new model for studying the dependencies between the logarithm of the size, the logarithm of the duration, and the logarithm of the transmission rate of an Internet flow. We consider a bivariate lognormal distribution for the flow size and flow duration, and derive estimators for the mean, the variance and the correlation, based on a truncated domain that reflects the upper-bounds on the duration and rate of measured flows. Moreover, we obtain regression equations that describe the expected value of one characteristic (size, duration or rate) given other (size or duration), thus providing further insights on the dependencies between Internet flow characteristics. In particular, for flows with large sizes we are able to predict durations and rates that are coherent with the upper-bound on transmission rates imposed by the network.

Machine learning techniques to make computers easier to use
Authors: Hiroshi Motoda, Kenichi Yoshida
Venue: Proceedings of the Fifteenth international joint conference on Artifical intelligence - Volume 2 (1997)

Identifying user-dependent information that can be automatically collected helps build a user model by which to predict what the user wants to do next and to do relevant preprocessing. Such information is often relational and is best represented by a set of directed graphs. A machine learning technique called graph-based induction (GBI) efficiently extracts regularities from such data, based on which a user-adaptive interface is built that can predict next command, generate scripts and prefetch files in a multi task environment. The heart of GBI is pairwise chunking. The paper shows how this simple mechanism applies to the top down induction of decision trees for nested attribute representation as well as finding frequently occurring patterns in a graph. The results clearly shows that the dependency analysis of computational processes activated by the user commands which is made possible by GBI is indeed useful to build a behavior model and increase prediction accuracy.
Designing spheres of informational justice
Authors: Michael Nagenborg
Venue: Ethics and Information Technology (2009)

J. van den Hoven suggested to analyse privacy from the perspective of informational justice, whereby he referred to the concept of distributive justice presented by M. Walzer in "Spheres of Justice". In "privacy as contextual integrity" Helen Nissenbaum did also point to Walzer's approach of complex equality as well to van den Hoven's concept. In this article I will analyse the challenges of applying Walzer's concept to issues of informational privacy. I will also discuss the possibilities of framing privacy from the point of the "art of separation" by looking at the intersection of information infrastructures and institutions.

Differential synchronization
Authors: Neil Fraser
Venue: Proceedings of the 9th ACM symposium on Document engineering (2009)

This paper describes the Differential Synchronization (DS) method for keeping documents synchronized. The key feature of DS is that it is simple and well suited for use in both novel and existing state-based applications without requiring application redesign. DS uses deltas to make efficient use of bandwidth, and is fault-tolerant, allowing copies to converge in spite of occasional errors. We consider practical implementation of DS and describe some techniques to improve its performance in a browser environment.
The Cryptanalysis of Reduced-Round SMS4
Authors: Jonathan Etrog, Matt J. Robshaw
Venue: Selected Areas in Cryptography: 15th International Workshop, SAC 2008, Sackville, New Brunswick, Canada, August 14-15, Revised Selected Papers (2009)

In this paper we consider the cryptanalysis of the block cipher SMS4. The cipher has received much recent attention due its simplicity and prominence (it is used in wireless networks in China) and a range of differential attacks break up to 21 of the 32 rounds used in SMS4. Here we consider the application of linear cryptanalysis to the cipher and we demonstrate a simple attack on 22 rounds of SMS4. We also consider some advanced linear cryptanalytic techniques which, under the best conditions for the cryptanalyst, might (just) extend to 23 rounds.
User Profiling for Web Search Based on Biological Fluctuation
Authors: Yuki Arase, Takahiro Hara, Shojiro Nishio
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part III: Ubiquitous and Intelligent Interaction (2009)

Because of the information flood on the Web, it has become difficult to search necessary information. Although Web search engines assign authority values to Web pages and show ranked results, it is not enough to find information of interest easily, as users have to comb through reliable but out of the focus information. In this situation, personalization of Web search results is effective. To realize the personalization, a user profiling technique is essential, however, since the users' interests are not stable and are versatile, it should be flexible and tolerant to change of the environment. In this paper, we propose a user profiling method based on the model of the organisms' flexibility and environmental tolerance. We review the previous user profiling methods and discuss the adequacy of applying this model to user profiling.
The communicative multiagent team decision problem: analyzing teamwork theories and models
Authors: David V. Pynadath, Milind Tambe
Venue: Journal of Artificial Intelligence Research (2002)

Despite the significant progress in multiagent teamwork, existing research does not address the optimality of its prescriptions nor the complexity of the teamwork problem. Without a characterization of the optimality-complexity tradeoffs, it is impossible to determine whether the assumptions and approximations made by a particular theory gain enough efficiency to justify the losses in overall performance. To provide a tool for use by multiagent researchers in evaluating this tradeoff, we present a unified framework, the COMmunicative Multiagent Team Decision Problem (COM-MTDP). The COM-MTDP model combines and extends existing multiagent theories, such as decentralized partially observable Markov decision processes and economic team theory. In addition to their generality of representation, COM-MTDPs also support the analysis of both the optimality of team performance and the computational complexity of the agents' decision problem. In analyzing complexity, we present a breakdown of the computational complexity of constructing optimal teams under various classes of problem domains, along the dimensions of observability and communication cost. In analyzing optimality, we exploit the COM-MTDP's ability to encode existing teamwork theories and models to encode two instantiations of joint intentions theory taken from the literature. Furthermore, the COM-MTDP model provides a basis for the development of novel team coordination algorithms. We derive a domain-independent criterion for optimal communication and provide a comparative analysis of the two joint intentions instantiations with respect to this optimal policy. We have implemented a reusable, domain-independent software package based on COM-MTDPs to analyze teamwork coordination strategies, and we demonstrate its use by encoding and evaluating the two joint intentions strategies within an example domain.
Marker-Less Tracking for Multi-layer Authoring in AR Books
Authors: Kiyoung Kim, Jonghee Park, Woontack Woo
Venue: Proceedings of the 8th International Conference on Entertainment Computing (2009)

An Augmented Reality (AR) book is an application that applies AR technologies to physical books for providing a new experience to users. In this paper, we propose a new marker-less tracking method for the AR book. The main goal of the tracker is not only to recognize many pages, but also to compute 6 DOF camera pose. As a result, we can augment different virtual contents according to the corresponding page. For this purpose, we use a multi-core programming approach that separates the page recognition module from the tracking module. In the page recognition module, highly distinctive Scale Invariant Features Transform (SIFT) features are used. In the tracking module, a coarse-to-fine approach is exploited for fast frame-to-frame matching. Our tracker provides more than 30 frames per second. In addition to the tracker, we explain multi-layer based data structure for maintaining the AR book. A GUI-based authoring tool is also shown to validate feasibility of the tracker and data structures. The proposed algorithm would be helpful to create various AR applications that require multiple planes tracking.

Authors: Harumi Kashiwagi, Yan Xue, Yi Sun, Min Kang, Kazuhiro Ohtsuki
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part IV: Interacting in Various Application Domains (2009)

In this paper, we present a method of integrating a CALL system with RFID tags in a classroom in order to provide the basic support for listening activities based on the concept of Total Physical Response (TPR) Approach. We designed and developed a prototype system with the function of providing corrective feedback. The prototype system has the following three features: (1) Real objects are used as the options for responding to audio questions. (2) A considerable amount of attribute information is used to increase the variation in the questions. (3) The system has a function of providing error messages and additional questions, depending on the degree of a learner's mistakes. Results from the experiment suggest that integrating real objects into the learning system by using RFID tags has a potential impact on the language learners.
Camera-Model Identification Using Markovian Transition Probability Matrix
Authors: Guanshuo Xu, Shang Gao, Yun Qing Shi, Ruimin Hu, Wei Su
Venue: Proceedings of the 8th International Workshop on Digital Watermarking (2009)

Detecting the (brands and) models of digital cameras from given digital images has become a popular research topic in the field of digital forensics. As most of images are JPEG compressed before they are output from cameras, we propose to use an effective image statistical model to characterize the difference JPEG 2-D arrays of Y and Cb components from the JPEG images taken by various camera models. Specifically, the transition probability matrices derived from four different directional Markov processes applied to the image difference JPEG 2-D arrays are used to identify statistical difference caused by image formation pipelines inside different camera models. All elements of the transition probability matrices, after a thresholding technique, are directly used as features for classification purpose. Multi-class support vector machines (SVM) are used as the classification tool. The effectiveness of our proposed statistical model is demonstrated by large-scale experimental results.
The next 700 programming libraries
Authors: Antonio Menezes Leitao
Venue: Proceedings of the 2007 International Lisp Conference (2007)

Modern software requirements are more diverse than before and can only be timely fulfilled via the extensive use of libraries. As a result, modern programmers spend a significant fraction of their time just mixing and matching these libraries. Programming language success becomes, then, more dependent on the quality and broadness of the accompanying libraries than on the language intrinsic characteristics. In spite of its recognized qualities, Common Lisp lags behind other languages as regards the quality and availability of its libraries. We argue that the best solution to overcome this problem is to automatically translate to Common Lisp the best libraries that are available in other languages. In this paper, we specifically address the translation of Java libraries using the Jnil translator tool and we provide a detailed explanation of the problems found and the lessons learned during the translation of a large Java library. Although many problems remain to be solved, the experiment proved the feasibility of the translation process and significantly increased our confidence in the future of Common Lisp.
Research and Practical Progress on Information Service Transformation
Authors: Qingling Yue, Zhaogui Qin
Venue: Proceedings of the 2009 IITA International Conference on Services Science, Management and Engineering (2009)

Guided by the requirement changing of innovation, every country is frequently adjusting development strategy to reconstructing the information service. This paper takes the method of document analysis to study the research and practice of information service transformation in different countries and find the concerns of scholars and the trend of modern information service industry development. Objectively speaking, nowadays research on information service transformation is lagging behind the practical development. The academic field hasn’t put enough focus on the problems came out of the transformation process, and rarely make innovations. The research contents are over emphasized on the technology, while the research on management system, operation system and relative principles are insufficient.
