[SIPTA] CFP URSW 2013 (deadline extended)

by Thomas Lukasiewicz

CALL FOR PAPERS 9th International Workshop on Uncertainty Reasoning for the Semantic Web http://c4i.gmu.edu/ursw/2013 In conjunction with the 12th International Semantic Web Conference (ISWC'13) Sydney, Australia October 21-22, 2013 >>>>> New paper submission deadline: 24th July, 2013 <<<<< ISWC is a major international forum for presenting visionary research on all aspects of the Semantic Web. The Uncertainty Reasoning for the Semantic Web (URSW) workshop at ISWC'13 is an exciting opportunity for collaboration and cross-fertilization between the uncertainty reasoning community and the Semantic Web / Linked Data community. Effective methods for reasoning under uncertainty are vital for realizing many aspects of the Semantic Web vision, but the ability of current-generation web technology to handle uncertainty remains extremely limited. Thus, there is a continuing demand for uncertainty reasoning technology among Semantic Web researchers and developers, and the URSW workshop creates a unique opening to bring together two communities with a clear commonality of interest but limited history of interaction. By capitalizing on this opportunity, URSW could spark dramatic progress toward realizing the Semantic Web vision. AUDIENCE The intended audience for this workshop includes the following: - Researchers in uncertainty reasoning technologies with interest in Semantic Web / Linked Data and Web-related technologies; - Semantic Web and Linked Data developers and researchers; - People in the knowledge representation community with interest in the Semantic Web / Linked Data; - Ontology researchers and ontological engineers; - Web services and cloud computing researchers and developers with interest in the Semantic Web / Linked Data. TOPIC LIST We intend to have an open discussion on any topic relevant to the general subject of uncertainty in the Semantic Web and Linked Data (including fuzzy theory, probability theory, and other approaches). Therefore, the following list should be just an initial guide: - Syntax and semantics for extensions to Semantic Web / Linked Data languages to enable representation of uncertainty; - Logical formalisms to support uncertainty in Semantic Web / Linked Data languages; - Probability theory as a means of assessing the likelihood that terms in different ontologies refer to the same or similar concepts; - Architectures for applying plausible reasoning to the problem of ontology mapping; - Using fuzzy approaches to deal with imprecise concepts within ontologies; - The concept of a probabilistic ontology and its relevance to the Semantic Web; - Best practices for representing uncertain, incomplete, ambiguous, or controversial information in the Semantic Web / Linked Data; - The role of uncertainty as it relates to web services and cloud computing; - Interface protocols with support for uncertainty as a means to improve interoperability among web services; - Uncertainty reasoning techniques applied to trust issues in the Semantic Web and Linked Data; - Existing implementations of uncertainty reasoning tools in the context of the Semantic Web and Linked Data; - Issues and techniques for integrating tools for representing and reasoning with uncertainty; - The future of uncertainty reasoning for the Semantic Web and Linked Data. IMPORTANT DATES >>> July 24, 2013 (updated!): Paper submissions due <<< August 9: Paper acceptance notification August 31: Camera-ready papers due October 21-22: 9th Workshop on Uncertainty Reasoning for the Semantic Web SUBMISSION DETAILS The URSW workshop will be accepting submissions of technical papers and position papers. Each submission will be evaluated for acceptability by at least three members of the Program Committee. Decisions about acceptance will be based on relevance to the above topic list, originality, potential significance, topicality and clarity. Since all accepted papers will be presented at the workshop, we require that at least one of the submitting authors must be a registered participant at the ISWC 2013 Conference, and committed to attend the URSW workshop. Submissions to the workshop are only accepted in electronic format and should be sent via the workshop’s submission site: https://www.easychair.org/account/signin.cgi?conf=ursw2013. Papers must be formatted in the style of the Springer Publications format for Lecture Notes in Computer Science (LNCS). This is the very same format adopted by the ISWC 2013. For complete details, see Springer’s Author Instructions (http://www.springer.com/computer/lncs?SGWID=0-164-6-793341-0) Technical papers submitted to the URSW workshop must not exceed 12 pages, including figures and references. Submissions exceeding this limit will not be reviewed. Position papers consist of a summary of ideas, projects, or any research efforts that are relevant to the URSW workshop and must not exceed 4 pages. Following the general acceptance rules of the ISWC 2013 conference, papers that, at the time of submission, are under review for or have already been published in or accepted for publication in a journal or another conference will not be accepted to the URSW workshop. PRESENTATION AND PUBLICATION URSW 2013 will be a half-day workshop. All papers accepted for URSW will be presented during the workshop and published in the workshop proceedings. Authors of accepted technical papers will have 20 minutes to present their work, while authors of accepted position papers will have a 10-minute slot to share their ideas. After each presentation, 5 minutes will be allocated to questions from the audience. Both technical and position papers will be published in the URSW workshop proceedings, to be available after the ISWC 2013 Conference. In addition, extended and revised versions of selected technical papers presented at URSW 2013 will be eligible for participating in an international journal special issue or in a post-proceedings book.

[SIPTA] [CFP] SeRSy@ACM RecSys 2013 - 2nd International Workshop on Recommender Systems meet Big Data & Semantic Technologies

by Thomas Lukasiewicz

Apologies for possible multiple posts ============================ CALL FOR PAPERS ============================ 2nd International Workshop on Recommender Systems meet Big Data & Semantic Technologies - SeRSy 2013 in conjunction with RecSys 2013, Hong Kong, October 12-16, 2013 http://sisinflab.poliba.it/sersy2013/ http://recsys.acm.org/recsys13/sersy/ MOTIVATION ---------- Recommendation techniques generally rely on data referring to three kinds of objects: users, items and their relations. The widespread success of Semantic Web techniques, creating a Web of interoperable and machine readable data, offers novel strategies to represent data 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. Indeed, 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 significantly improve complex search and filtering tasks that cannot be solved merely through a straightforward matching of queries (or user profiles) and items. Such tasks involve finding information from large document collections, categorizing and understanding that information, and producing some output, such as an actionable decision. 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. TOPICS ------- Topics of interest include (but are not limited to): - Recommendation approaches exploiting Big Data and Semantic technologies - Linked Data for Recommender Systems - Ontology-based recommendation algorithms - Reasoning with Big Data - Discovery of relevant Linked Data sources for recommendation algorithms - Linking, aggregating, intertwining and mining Linked Data for recommender systems - Linked Data in new Recommender Systems architectures - Semantic technologies for Cross-lingual and cross-domain recommender systems - Semantic technologies for improving transparency and explanations - Big datasets for the evaluation - Evaluation methodologies for real time personalization in big datasets - Semantic technologies for improving novelty, diversity and serendipity SUBMISSION ----------------------- We welcome work at all stages of development: papers can describe applied systems, empirical results or theoretically grounded positions. Accepted papers will be published as CEUR workshop proceedings (http://ceur-ws.org) Based on the quality of accepted papers we are planning to schedule a special issue of a top-level journal in 2013. * Full papers (5-6 pages) * Short papers (2-3 pages) * Demos (1-2 pages for description) Papers should be formatted according to the general RecSys2013 submission guidelines.
