DaWaK 2007 : Submission site is ready
by Nguyen Manh Tho 17 Mar '07

17 Mar '07

Apologies for multiple copies due to cross postings. Please send to interested colleagues and students. DaWaK 2007 Submission online available at: https://www.ares-conf.org/dawak/ Important Dates: Submission of abstracts: April 2, 2007 Submission of full papers: April 13, 2007 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++ 9th International Conference on Data Warehousing and Knowledge Discovery (DaWaK 2007) Regensburg, Germany Sept. 3 to Sept. 7, 2007 http://www.dexa.org/drupal/?q=dawak ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++ Call for Papers =================== Data Warehousing and Knowledge Discovery has been widely accepted as a key technology for enterprises and organisations to improve their abilities in data analysis, decision support, and the automatic extraction of knowledge from data. With the exponential growing amount of information to be included in the decision making process, the data to be considered becomes more and more complex in both structure and semantics. Consequently, the process of retrieval and knowledge discovery from this huge amount of heterogeneous complex data builds the litmus-test for the research in the area. During the past years, the International Conference on Data Warehousing and Knowledge Discovery (DaWaK) has become one of the most important international scientific events to bring together researchers, developers and practitioners to discuss latest research issues and experiences in developing and deploying data warehousing and knowledge discovery systems, applications, and solutions. This years conference (DaWaK 2007), builds on this tradition of facilitating the cross-disciplinary exchange of ideas, experience and potential research directions. DaWaK 2007 seeks to introduce innovative principles, methods, algorithms and solutions to challenging problems faced in the development of data warehousing, knowledge discovery and data mining applications. Submissions presenting current research work on both theoretical and practical aspects of data warehousing and knowledge discovery are encouraged. Particularly, we strongly welcome submissions dealing with emerging real world applications such as real-time data warehousing, analysis of spatial and spatiotemporal data, OLAP mining, mobile OLAP, mining natural science data (e.g. bioinformatics, geophysics) Major Tracks =============== Topics of interest include in these tracks but are not limited to: Data Warehousing =================== Analytical front-end tools for data warehousing/OLAP Active/real-time data warehousing Data warehouse architecture Web/multimedia data warehouses Data extraction, cleansing, transforming and loading Spatial and spatiotemporal data warehouses Data warehouse maintenance and evolution Data warehousing in mobile/wireless environments Data warehouse design (conceptual, logical and physical) Data warehousing and the semantic web Data warehousing consistency and quality Data warehouse schema evolution and transformations Data warehousing with unstructured data (e.g., text) and semi-structured data (e.g., XML) Design and maintenance of metadata repository Data warehouse security and reliability Data warehousing applications: corporate, scientific, government, healthcare, bioinformatics, etc. Parallel /distributed data warehousing View maintenance/adaptation Frameworks for Business Process Management (BPM) and Business Intelligence (BI) Performance optimization and tuning Multidimensional modelling and queries Data warehousing and industry applications (e.g. ERP, CRM) Integration of data warehouses and data mining Knowledge Discovery ====================== Knowledge discovery framework and process Security, privacy and social impact of data mining Integration constraints and knowledge in KDD process Mining unstructured and structured data Data and knowledge representation Exploring data analysis, inference of causes, prediction Evaluating, consolidating, and explaining discovered knowledge Statistical techniques for generation a robust, consistent data model Interactive data exploration/visualization and discovery Mining temporal, spatial and multimedia data Data mining techniques: clustering, classification, association rules, decision trees, neural-network, etc Mining large/complex datasets, continuous data streams, sensor networks Data mining support for the design of information systems Mining ubiquitous, moving, time-series data Integration of data warehousing, OLAP and data mining Mining Trends, Opportunities and Risks Languages and interfaces for data mining Distributed and parallel data mining/knowledge discovery Mining from low-quality information sources High performance and parallel/distributed data mining Complexity, efficiency, and scalability in data mining Pre-processing and post-processing of data mining Data mining applications: bioinformatics, E-commerce, Web, intrusion/fraud detection, finance, healthcare, marketing, telecommunications, etc Paper Submission Details ========================== Authors are invited to submit research and application papers representing original, previously unpublished work. Papers should be submitted in PDF or Word format. Submissions must conform to Springer's LNCS format and should not exceed 10 pages (including all text, figures, references and appendices). Authors who want to buy extra pages may submit a paper up to 12 pages with the indication that the authors will purchase extra pages once the paper is accepted. Submissions which are not conform to the LNCS format and/or which do exceed 10 pages (or up to 12 pages with the extra page purchase commitment) will be rejected without reviews. Submitted papers will be carefully evaluated based on originality, significance, technical soundness, and clarity of exposition. All accepted papers will be published in Lecture Notes in Computer Science (LNCS) by Springer-Verlag. Duplicate submissions are not allowed. A submission is considered to be a duplicate submission if it is submitted to other conferences/workshops/journals or it has been already accepted to be published in other conferences/workshops/journals. Duplicate submissions thus will be automatically rejected without reviews. This year, we will plan to have the Best Paper Awards for the best papers selected by the PC-members. As the last year, authors of best papers selected from DaWaK2007 conference will be invited to submit an extension for a special issue of International Journal of Data Warehousing and Mining (IJDWM). Authors are requested to send the abstract of their paper to be received by April 2nd 2007, due date of the full paper electronic submission is April 13th 2007.

Late Arrival & Resource Workflow Conceptualization
by Donal K. Fellows 13 Mar '07

13 Mar '07

Hi everyone! I'm sorry to say that I'm going to be arriving late at the F2F. I missed my flight due to bad weather, and so I had to go onwards a day later. I'll be arriving sometime on Wednesday afternoon, depending on how long it takes to get my bags and the hire-car, as well as the traffic (though the last time I arrived on that flight, the traffic wasn't a big deal). I'm especially annoyed to be missing the Workflow discussion and the Data grid use-cases, but I'll be in the air or on the road when those are on. I suspect I'll arrive sometime during the QoS part. Since I'm not going to be in the Workflow discussion, I'll instead write about an idea I've been working on as part of the EU BREIN project. It is an attempt to produce a conceptualization of Workflows based on (abstract) Resources instead the more conventional ideas of Services, Messages or Jobs. It's specifically intended to be a conceptualization, and as such it does not make *any* attempt to define an actual language or concrete terms for things covered by the likes of JSDL or BES (or even CIM for that matter). It's much more abstract than that right now. The document so far is available in the Workflow Design Team area of the OGSA documents tree on GridForge. I was going to put it in here, but I object to receiving large documents through email and I assume others do too. :-) Alas, the style used is not very nice; that's driven by project requirements. A few things to note about what I've done with it so far. I'm fairly sure I can capture the vast majority of resources, including things like CPUs, batch queues, applications, networks, disk space. I think I can also capture the notions of reservations, software licenses. The key to this is a three-layer model: 1: Locality - represents a space in which resources exist. 2: Resource - represents something that can be allocated, and which has some kind of usage/consumption pattern. (I do not know whether access control should be applied at the level of the locality or the resource.) 3: Aspect - represents a description of a view on a resource. I've identified three basic consumption patterns, being: * Presence Required - resource must be present in the locality for the duration of an activity using the resource * Exclusive Hold - resource must be present in locality at start of the activity, is removed/hidden from the locality while the activity is processing, and is returned to the locality when the activity completes * Consume - as with Exclusive Hold, except that upon activity completion the resource is destroyed and not returned to the locality Activities gain access to resources by describing which aspects they require and in how many localities; resources are not referred to directly (though since resources have a unique name, using that as an aspect is trivial). I don't define any logic for combining aspects (an aspect's description could be bounded in time, which is necessary for characterizing reservations using the intermediate concept of allocated time slices) or subsuming them (so an Intel Core 2 Duo is more specific than an x86, but still capable of satisfying a request for an x86), though I feel that such a logic is a Very Good Idea (if furiously difficult to define). When an activity's required aspects are satisfied, it may execute, and upon finishing execution, may create further resources in one or more localities. Such result resources (which another activity may depend upon) represent the outcome of the activity, and might also include things like a transferred dataset or a deployed software system. Result resources won't "overwrite" any resource with the same name, though they may be unnamed, in which case a new (globally?) unique name will be chosen for them at creation time. A workflow is just a set of activities that presumably depend on each other (though I suppose they don't have to) and a workflow is said to be complete when no activities are enabled (i.e. have their aspect requirements satisfiable) or the action of any enabled activity would force the overwrite of one or more named resources. It is obviously possible to define a workflow that is always creating more and more resources by having an activity that only produces unnamed resources; don't do that! :-) A few examples of actions: * Simple job execution: the action requires aspects from a single locality that correspond to the resources and application name/version that you'd expect based on a JSDL description of the job. * Dataset transfer: the action requires an aspect that corresponds to the dataset in the source locality, and another aspect that corresponds to sufficient free disk space in the target locality. If using some sort of network reservation, requiring an aspect for bandwidth from the locality/ies representing the network between the source and the target is a good idea. * Distributed metacomputing: the action is like a simple job execution on several distinct localities, and quite possibly with some extra requirements on the network locality/ies for bandwidth and/or latency. Known open questions: * Undeployment of resources that are not typically Consumed. * Access control (especially the locus of AuthZ decisions). * Whether localities are themselves resources. * How good the model of reservations is! * Whether localities need to be referred to explicitly by actions and how localities and action aspect requirements interact in the description of actions. * How much quality-of-service can be described as aspects on suitable resources. Feedback is definitely welcome on this idea, which is definitely an example of a product of the half-bakery. But I think it has merit (especially as it is not the same as either Orchestration or Choreography as I understand it; I expect these ideas to instead complement more standard workflows) especially when applied to the sorts of things which come up on the Grid. Acknowledgements: This is purely my own work, but many people were responsible for the forment of ideas from which it sprang. The following people are especially notable: * Jay Ungar, who started me thinking about abstract resources and workflows * Dean Kuo and Viktor Yarmolenko at Manchester, who started me thinking about abstract actions and reservations * My colleagues from the BREIN project, especially from the Agents group at the University of Hohenheim, who helped me understand what sorts of abstractions are needed in (some kinds of) workflows Hmm, this message has turned out to be rather longer than I originally anticipated! My apologies. Donal Fellows (stuck overnight in Amsterdam, on the grounds that it is less awful than being stuck in JFK).

GIN documentation process: First GIN-INFO draft (v.1.00) available
by Morris Riedel 13 Mar '07

13 Mar '07

Dear GIN team, I have compiled a first draft of the experience document in the area of GIN-INFO that is available from: http://indico.cern.ch/materialDisplay.py?sessionId=4 <http://indico.cern.ch/materialDisplay.py?sessionId=4&materialId=0&c onfId=12489> &materialId=0&confId=12489 This document is not ready yet - I'm currently waiting for feedback, especially from people of GIN-INFO (I got Laurence comments already). This document will be discussed in my session tomorrow - so have a look at the document if possible to provide feedback. Furthermore, I started a similar document for GIN-JOBS already, while Dane Skow plans to do the same for GIN-AUTH. An early draft of GIN-JOBS will be presented tomorrow as well. Early drafts of GIN-DATA and GIN-OPS will be next after GIN-JOBS. So, people that would like to contribute to these documents should send me the following: (1) name (2) affiliation (3) three sentences what you did in GIN (4) documents to which you would like to contribute Finally, some of the OGSA-WG members have already stated interest in the GIN-INFO experience document - so let us get this ready as soon as possible. More details tomorrow during the session.
