In this work, we study processing an l-keyword query (p1, p2, ..., pl) against a relational database which can be modeled as a weighted graph, G(V, E). Here V is a set of nodes (tuples) and E is a set of edges representing foreign key references between tuples. Let Vi be a set of nodes that contain the keyword pi. We study finding top-k minimum cost connected trees that contain at least one node in every subset Vi. We denote our problem as GST-k. When k = 1, it is known as a minimum cost group Steiner tree problem which is NP-Complete. We observe that the number of keywords, l, is small, and propose a novel parameterized solution, with l as a parameter, to find the optimal GST-1, in better time complexity. Our solution can handle graphs with a large number of nodes. Our GST-1 solution can be easily extended to support GST-k, which outperforms the existing GST-k solutions over both weighted undirected/directed graphs. We conducted extensive experimental studies, and report our finding. ----------------------------------------------------------------------- 中野　美由紀東京大学　生産技術研究所　喜連川研究室 Miyuki NAKANO Institute of Industrial Science, Univ. of Tokyo miyuki(a)tkl.iis.u-tokyo.ac.jp

The First Workshop on Community Computing W2. The Fourth Workshop for Ubiquitous Networking and Enablers to Context-Aware Services W3 Dependable Ubiquiotus Nodes (IWDUN) W4 Int'l Workshop on Real Field Identification (RFId2007) ________________________________________ W1. The First Workshop on Community Computing Organizers: Minkoo Kim (Ajou University) and Hideyuki Nakashima (Future University, Hakodate) Community computing is a new paradigm for building ubiquitous systems which can solve problems by the collaboration of entities in ubiquitous environment. Community computing makes the collaborative and adaptive service development more intuitive and natural. Many people are researching various topics for community computing including context modeling, wireless and sensor networks, and smart objects in the field of ubiquitous computing. This workshop is intended to act as a focal point for researchers and practitioners whose works are related to community computing, to enable them to share their ideas and experiences. Topics: Topics include, but are not limited to: * Models or Studies for cooperation system in Ubiquitous environment * Smart Object Designs and implementations for Community Computing * Middleware or infrastructure for Community Computing * Context Modeling for Community Computing * Security and Privacy issues in Community Computing * Case Studies with Community Computing Systems * Communication issues in Community Computing * Collaboration with Multi-Agent System Contact: Minsoo Kim(visual[AT]ajou.ac.kr), Ajou Univ., Korea ________________________________________ W2. The Fourth Workshop for Ubiquitous Networking and Enablers to Context-Aware Services Organizers: Chair organizer:　Shinji Shimojo (Osaka University) Organizers:　Yuuichi TERANISHI & Kaname HARUMOTO (Osaka University), Junzo KAMAHARA (Kobe University), Takeshi OKUDA (Nara Institute of Science and Technology), Hiroshi SUNAGA & Michiharu TAKEMOTO (NTT). A "ubiquitous networking" is a federated network technology which supports various enablers such as 3G mobiles, RFID tags, sensors, actuators, etc. It has enough capability to deal with huge number of IP packets generated from enablers. At the same time, a lot of broadband contents are requested to be delivered with perfectly controlled QoS. Efficient and scalable routing and transport mechanism for supporting such various traffics are fundamental requirement on the network. From a service perspective, a number of context or ambient aware services are envisaged for "ubiquitous networking." A service platform will manage and create services based on the context. There should be discussions how to collect and generate user context, how to create or synthesize services efficiently, and how to develop such systems using emerging software and hardware technologies. There could be also discussions how to control network performance based on user policy or service level agreement. Providing robust security over all ubiquitous networks in a simple fashion is an important issue associated with service provisioning to users. Keeping privacy in ubiquitous networks is also a big issue. The other important aspect is enablers or ubiquitous objects themselves where users are commonly faced with. What is a suitable design and implementation of such objects? How they could be connected to a ubiquitous network to provide contexts or how could they communicate with each other? This Workshop is one of the best opportunities to address this theme in sufficient depth and breadth, and is intended to share knowledge and exchange ideas, thereby promoting new studies and research topics in this area. Papers should be sent to the Organizers at "ucs2007-ws-ubiq-nw[AT]lab.ntt.co.jp" no later than 31 Aug., 2007.

Dependable Ubiquiotus Nodes (IWDUN) Organizers: Hideyuki Tokuda (Keio University), Michael Beigl (TU Braunschweig), Kazunori Takashio, Jin Nakazawa and Masayuki Iwai　(Keio University) Recent years have seen a rapid proliferation of micro ubiquitous nodes. As well as o-the-shelf cellular phones, mobile audio players, and portable game devices, wireless sensor nodes are of great interest for researchers especially for devel- oping ubiquitous computing systems. Among those proposed by the academia, particle nodes and Motes have been commercialized so that we can deploy them for practical applications like environmental monitoring, remote health care, and context captures. Despite the range of development of sensor nodes, systems support that ensures their dependability has not been investigated. We believe that the use of such micro ubiquitous nodes in practical applications necessi-tates the systems support that enables users to leverage from those applications without being burdened by malfunction of the nodes, malicious users attacking them, or inconsistent behaviors of them. The primary motivation of this work- shop is hence to nding research issues inherent in achieving dependable micro ubiquitous nodes, looking at existing research on them, and systems on them. Topics: * Application Scenarios Deserving Dependability * Middleware Support for Dependability. * Operating Systems Support for Dependability * Surveys on Dependability for Embedded Systems * Programming Paradigm * Operating Systems Model * Experiences on Dependable Sensor Nodes * Micro Ubiquitous Nodes Contact: Jin Nakazawa(jin[AT]ht.sfc.keio.ac.jp), Keio University ________________________________________ W4. Int'l Workshop on Real Field Identification (RFId2007) Organizers: Sozo Inoue(Kyusyu University), Mitsuo Tsukada (NTT), Marc Langheinrich (ETH), George Roussos (Univ. London), Benessa Defend (UMASS Amherst), Yasunobu Nohara (Kyushu Univ.), Yuichiro Yamaguchi (Oki Electric), Tomoki Yoshihisa (Kyoto Univ.), Yutaka Yanagisawa (NTT), Miyako Ohkubo (IPA) We define RFId (Real Field IDentification) as a technology for identifying, recognizing, and/or authenticating objects, events, and/or contexts in the real world. It includes of course RFID (Radio Frequency IDentification), smart devices as sensors, and/or various recognition techniques, with a strong tie with platform software/hardware, and applications. As a result of recent proposals and trials for the technology, fundamental techniques are facing the needs to be tried in the real field, and application experiences are to be fed back to new research challenges. In this workshop, we encourage contributions for interacting these aspects of RFId Topics: RFId as/for * Identification (with/without new devices) * Recognition * Infrastructure * Location Services * Security/Privacy * Data Management * Scalability * Deployment * Real Applications * Business Models * Social Acceptance Contact: Sozo Inoue(sozo[AT]lib.kyushu-u.ac.jp), Kyusyu University ________________________________________ Workshop Chair Masayoshi Ohashi, KDDI R&D Labs Japan ma-oohashi[AT]kddi.com For further information, please visit <http://http://www.ht.sfc.keio.ac.jp/ucs2007/>

A prominent example of this Web spam is the targeted manipulation of link-based ranking systems to increase the rankings (and, hence, the amount of user traffic) of particular Web pages, regardless of the intrinsic merits of those pages. Interestingly, popular link-based Web ranking algorithms like PageRank, HITS, and TrustRank rely on a fundamental assumption that the quality of a page and the quality of a page's links are the same. In this talk, we analyze link-based web spasm and propose the concept of link credibility and argue that the intrinsic quality of a page in terms of its content should be distinguished from its intrinsic link credibility. Concretely, we propose several techniques for semi-automatically assessing link credibility for all Web pages, since manually determining the link redibility of every page on the Web is infeasible. Second, we propose a novel credibility-based Web ranking algorithm -- CredibleRank. The new ranking algorithm incorporates link credibility information directly into the quality assessment of each page on the Web. CredibleRank effectively counters the influence of link hijacking, honeypots, and other spammer attacks that seek to corrupt link-based algorithms. Finally, we introduce concrete metrics for measuring the spam-resilience properties of ranking algorithms and show how the proposed credibility-based ranking algorithm outperforms both PageRank and TrustRank over real-world Web data of over 100 million pages.

Automated Application Deployment and Staging using Code Generation in Elba Project Prof. Calton Pu (Georgia Institute of Technology) ABSTRACT Large N-Tier applications running in data centers have complex deployment requirements and dependencies that change frequently. The increasing complexity and scalability requirements of such applications demand automated design, testing, deployment and monitoring of applications. The goal of Elba project is creating automated staging and testing of complex enterprise systems before deployment to production. Automating the staging process lowers the cost of testing applications and improves its reliability. Elba software tools extract test parameters from production specifications, such as SLAs, and deployment specifications, and via the Mulini generator, create staging plans for the application. A benchmark application, the TPC-W, is used to validate the generated configuration. Simple learning tools identify system bottlenecks and refine application deployments based on performance and cost. Biography : Calton Pu was born in Taiwan and grew up in Brazil. He received his PhD from University of Washington in 1986 and served on the faculty of Columbia University and Oregon Graduate Institute. Currently, he is holding the position of Professor and John P. Imlay, Jr. Chair in Software at the College of Computing, Georgia Institute of Technology. He is currently working on three areas. First, he is using automated code generation techniques to automate and ensure the correct deployment of large scale N-tier applications in the Elba project. Second, he is investigating software and statistical techniques to defend against Denial of Information attacks in areas such as email and web spam. Third, he is working on the application of specialization and other techniques to ensure the reliability, trust, and security of system and application software. He has been the principal investigator of the Infosphere, Synthetix, and Immunix projects, with technical contributions such as Epsilon Serializability, Reflective Transaction Framework, and Continual Queries over the Internet. His collaborations include applications of these techniques in scientific research on macromolecular structure data, weather data, and environmental data, as well as in industrial settings. He has published more than 50 journal papers and book chapters, 150 conference and refereed workshop papers, and served on more than 100 program committees, including the co-PC chairs of SRDS'95, ICDE・9, COOPIS・2, SRDS・3, and co-general chair of ICDE'97, CIKM'01, ICDE・6. 3. Spatial Alarms: Scalable Architecture and Energy-efficient Processing Techniques Prof. Ling Liu (Georgia Institute of Technology) Time based alarms are used by many on a daily basis. Spatial alarms extend the very same idea to location based triggers, which are fired whenever a mobile user enters the spatial region of the location alarms. Spatial alarms provide critical capabilities for many mobile location based applications ranging from personal assistants, inventory tracking to industrial safety warning systems. In this talk we present a scalable architecture for energy efficient processing of spatial alarms, while maintaining low computation and storage costs on mobile clients. Two important architectural designs are considered: Client-based and Sever-based solutions. In client based architecture, we focus on efficient techniques for processing spatial alarms while minimizing energy consumption on mobile clients. In Sever-based architecture, we focus on systematic methods for indexing spatial alarms, enabling efficient processing of public alarms, group-shared spatial alarms and private spatial alarms. In this talk we will first introduce the concept of safe distance to reduce the number of unnecessary mobile client wakeups for spatial alarm evaluation, enabling mobile clients to sleep for longer intervals of time in the presence of active spatial alarms. We show that our safe distance techniques can significantly minimize the energy consumption on mobile clients compared to periodic wakeups while preserving the accuracy and timeliness of spatial alarms. Second, we present a suite of techniques for minimizing the number of location triggers to be checked for spatial alarm evaluation upon each wakeup. This further reduces the computation cost and energy expenditure on mobile clients. We evaluate the scalability and energy-efficiency of our approach using a road network simulator. Our spatial alarms middleware architecture offers significant improvements on battery lifetime of mobile clients, while maintaining high quality of spatial alarm services, especially compared to the conventional approach of periodic wakeup and checking all alarms upon wakeup. -- ----------------------------------------------------------------------- 中野　美由紀東京大学　生産技術研究所　喜連川研究室 Miyuki NAKANO Institute of Industrial Science, Univ. of Tokyo miyuki(a)tkl.iis.u-tokyo.ac.jp
