[SIPTA] risk analysis

by Kreinovich

Dear Friends, I am currently attending a joint conference on risk and safety analysis PSAM/ESREL in Helsinki, Finland (my presentation was at an uncertainty session organized by Matthias Troffaes). I have learned a lot about risk analysis, the corresponding problems are very interesting and often misundertood. Misunderstanding comes from the fact that the word `risk' has two different meanings: in financial applications, any possibility to lose momey -- whether we know its probability or not -- is called risk. In this sense, taking risk into account is a part of normal decision making. In engineering applications of risk analysis, however, risk usually refers to rare events, events for which normal decision makers are not good in taking them into account. For example, when designing a nuclear power station, an offshore oil platform, or a space station, we need to take into account vey rare events, events that may lead to catastrophic consequences, such as an unusual strong earthquake at the location of the nuclear power station. To properly take such rare events into account, we need to estimate the probability of such an event. For usual events -- e.g., small earthquakes -- we can estimate their probability by looking into the past records and estimating the frequency of similar events in the past. For rare events, we may have one record in the distant past or no records at all, so we cannot estimate their probabilities as simply frequencies. Instead, we can, e.g., estimate the frequencies of earthquakes of different strength s and extrapolate -- e.g., if these probabilities follow the power law A*s^(-a) for some constants A and a -- to the desired strength S. As a result of an extrapolation, we do not get precisely known probabilities, we need imprecise probabilities -- and many imprecise probability techniques such as p-boxes (bounds on cumulative distribution functions) are indeed actively used in risk analysis. In the extrapolation, we can also use expert knowledge -- and several talks described how fuzzy techniques can be used to capture such knowledge. Risk analysis is an extremely important but still under-developed part of engineering design. I would like to join the conference organizers and participants in encouraging researchers to contribute ideas and results.

[SIPTA] URSW 2012: Call for Papers

[SIPTA] 1st CFP - Semantic Technologies meet Recommender Systems & Big Data

by Thomas Lukasiewicz

Apologies for possible multiple posts ============================ CALL FOR PAPERS ============================ International Workshop on Semantic Technologies meet Recommender Systems & Big Data - SeRSy 2012 in conjunction with ISWC 2012, Boston, USA, November 11-15, 2012 http://sisinflab.poliba.it/sersy2012/ IMPORTANT DATES --------------- Submission for workshop papers: Jul 31 Notification of acceptance: Aug 21 Camera-ready versions: Sep 10 MOTIVATION ---------- People generally need more and more advanced tools that go beyond those implementing the canonical search paradigm for seeking relevant information. A new search paradigm is emerging, where the user perspective is completely reversed: from finding to being found. Recommender Systems may help to support this new perspective, because they have the effect of pushing relevant objects, selected from a large space of possible options, to potentially interested users. To achieve this result, recommendation techniques generally rely on data referring to three kinds of objects: users, items and their relations. Recent developments of the Semantic Web community offer novel strategies to represent data about users, items and their relations that might improve the current state of the art of recommender systems, in order to move towards a new generation of recommender systems which fully understand the items they deal with. More and more semantic data are published following the Linked Data principles, that enable to set up links between objects in different data sources, by connecting information in a single global data space: the Web of Data. Today, Web of Data includes different types of knowledge represented in a homogeneous form: sedimentary one (encyclopedic, cultural, linguistic, common-sense) and real-time one (news, data streams, ...). This data might be useful to interlink diverse information about users, items, and their relations and implement reasoning mechanisms that can support and improve the recommendation process. The challenge is to investigate whether and how this large amount of wide-coverage and linked semantic knowledge can be automatically introduced into systems that perform tasks requiring human-level intelligence. Examples of such tasks include understanding a health problem in order to make a medical decision, or simply deciding which laptop to buy. Recommender systems support users exactly in those complex tasks. The primary goal of the workshop is to showcase cutting edge research on the intersection of Semantic Technologies and Recommender Systems, by taking the best of the two worlds. This combination may provide the Semantic Web community with important real-world scenarios where its potential can be effectively exploited into systems performing complex tasks. TOPICS ------- Topics of interest include (but are not limited to): Recommendation approaches using Semantic technologies - Linked Data for Recommender Systems - Ontology-based recommendation algorithms - Merging and ranking recommendations - Social recommender systems - Reasoning with Big Data Data Acquisition - Discovery of relevant Linked Data sources for recommendation algorithms - Tracking provenance, evaluating reliability, quality and trustworthiness of Linked Data - Linking, aggregating, intertwining and mining Linked Data for recommender systems - Integrity and privacy issues New Reference Architectures for Recommender Systems - Linked Data in new Recommender Systems architectures - Efficiency, performance and scalability issues - Distributed architectures Innovative applications - Semantic technologies for Cross-lingual and cross-domain recommender systems - Mining user data streams - Semantic technologies for improving transparency and explanations Evaluation methodologies and approaches - Big datasets for the evaluation - Evaluation methodologies for real time personalization in big datasets - Semantic technologies for improving novelty, diversity and serendipity FORMAT ----------------------- We welcome work at all stages of development: papers can describe applied systems, empirical results or theoretically grounded positions. * Full papers (10-12 pages) * Short papers (4-6 pages) * Demos (2-4 pages for description) Papers should be formatted according to the general ISWC2012 submission guidelines. Accepted format is PDF.

[SIPTA] WPMSIIP 2012: 2nd Announcement

by Marco Cattaneo

==================================================================== WPMSIIP 2012 (10-15 Sept 2012, Munich, Germany) --- 2nd Announcement ==================================================================== Dear friends and colleagues, The Working Group on Foundations of Statistics at the Department of Statistics, LMU Munich, organizes a workshop on principles and methods of statistical inference with interval probability. This workshop is a follow-up to four earlier WPMSIIPs held in Durham (2008, 2010), Munich (2009), and Ljubljana (2011). The WPMSIIP workshop runs from Monday 10 September until Saturday 15 September 2012. Each of the five workdays is focused on a specific topic, while on Saturday 15 an excursion is planned. The major aim of the workshop is to stimulate discussion of ongoing research in imprecise/interval probability theories, providing a platform to discuss unsolved problems and to address unanswered questions. Therefore, especially the afternoons are structured very informally. For more information and an outline of the tentative programme, please visit: http://www.statistik.lmu.de/institut/ag/statsoz_neu/research/WPMSIIP_2012/ Everyone, including PhD students, is welcome to participate and/or to present their views on one or more of the covered topics, on one or more days! We welcome any stimulating contribution, ranging from a presentation to a short informal statement. If you want to join the workshop, please contact Marco Cattaneo (cattaneo(a)stat.uni-muenchen.de) or the organisers of the specific day(s) that you would like to contribute to, preferably before the end of June.
