Message-ID: <4AC8DE87.3030905@inf.ed.ac.uk> Apologies for cross-postings ------------------------------------------------------------------------------ CALL FOR PAPERS ------------------------------------------------------------------------------ Workshop on Matching and Meaning: Automated development, evolution and interpretation of ontologies http://dream.inf.ed.ac.uk/events/wmm-2010 31st March 2010, part of AISB'10 Convention, Leicester, UK OVERVIEW The problem of semantic misalignment - of two (or more) systems failing to understand one another when their semantic representation is not identical - occurs in a huge variety of areas: the Semantic Web, databases, natural language processing; anywhere, indeed, where semantics are necessary but centralised control is undesirable or impractical. In highly dynamic domains, where interactions are between a large, diverse and evolving community, there is a need for the resolving of these misalignments - through developing and evolving existing ontologies or interpreting unknown ontologies in terms of known ones - to be done automatically and on-the-fly. The aim of this workshop is to bring together researchers interested in the problems of automated development, evolution and interpretation of ontologies in the many different domains in which it occurs. We are primarily interested in the exchange of ideas and the stimulation of debate, and the workshop is intended to be a forum for researchers to present ongoing work and ideas and to engage in discussion with other researchers from the field. We are particularly interested in novel ideas and innovative research, which may be in its early stages, and encourage reports on work in progress. Topics of interest include: * Ontology evolution * Ontology matching and alignment * Ontology versioning * Representational or structural change * Formal aspects of ontology dynamics * Formalisation of and reasoning with contexts * Foundational issues * Social and collaborative matching * Background knowledge in matching * Extensions to ontology languages to better support change * Non-monotonic reasoning for ontologies and the Semantic Web * Inconsistency handling in evolving ontologies * Uncertainty in matching * Change propagation in ontologies and metadata * Ontologies for dynamic environments * Dynamic knowledge construction and exploitation * Matching for dynamic applictions (e.g., p2p, agents, web-services) * Case studies, software tools, use cases, applications * Open problems SUBMISSION GUIDELINES We encourage the submission of extended abstracts of 2-5 pages that discuss ongoing research, problem descriptions and overviews of the domain. Accepted papers will be included in the AISB 2010 proceedings unless the authors prefer them not to be (for example, if the work is very similar to work presented elsewhere which they nevertheless feel it would be valuable to present in this context, or if the work is at a stage where discussion would be valuable but publication would be premature). Authors wishing their submissions to be included in the convention proceedings must follow the style guide on the convention website. Submissions will be subject to light reviewing, mainly intended to check fit to workshop. Abstracts should be submitted electronically in pdf format to mchan-at-ed.ac.uk by 18th December 2009. Notification of acceptance will be sent to the submitting author on 15th February 2010. VENUE The workshop will take place at De Montfort University in Leicester, as part of the AISB 2010 Convention (http://www.aisb.org.uk/convention/aisb10/), from March 31st to 1st April, 2010. All workshop participants must be registered for the AISB 2010 Convention. Registration for this workshop is included in the convention registration fee. IMPORTANT DATES Submission: Friday, 18th December 2009 Notification: Monday, 15th February 2010 Workshop: 31st March - 1st April 2010 AISB10 Convention: 29th March - 1st April 2010 PROGRAMME Presentations: Authors of accepted abstracts will give presentations of their work; exact times to be decided. Posters: If it is not possible to fit in presentations for all accepted authors, some may be asked to present posters instead. There will be a session of 5 minute poster talks. Panel: The technical programme will end with a 90 minute panel discussion on a topic of mutual interest to be decided. Three speakers will speak for 10 minutes each with a brief to stimulate debate during the remaining 60 minutes. Discussion amongst all participants, rather than question-and-answering for the panel, will be strongly encouraged.

Our hope is to integrate ideas from diverse domains such as (but not limited to) HCI, cognitive science, AI, psychology, computer science, information science, and computational linguistics to generate novel perspectives on understanding, characterizing, and predicting system characteristics and user behavior at both the individual and aggregate/ social levels. We also hope that his workshop will provide a venue for researchers in both academia and industry to discuss the use of cognitive models to inform designs of future social information systems in diverse application areas. We broadly define social information systems as systems that support social functions. Difference forms of social information systems have gained significant popularity over the last decade. For example, social networking sites such as Facebook and MySpace and social tagging systems such as del.icio.us and CiteUlike.org attract several thousand users a day. While serving different social functions, these systems provide its users increased social presence and opportunities for easy collaboration and social interaction. User behavior on these systems has been generally conducted based on analysis of snapshots of long-term user interaction patterns such as logs of user activities, connections between users, etc. But, very little is known about the cognitive mechanisms underlying these interactions. A good understanding of the individual cognitive mechanisms is important for engineering better interface representations and interaction methods that support user behavior in social systems. Additionally, models that aim at characterizing these mechanisms can complement existing research and provide a basis for a more complete explanation of emergent social and collaborative behavior in social information systems. Submission We welcome submission from researchers and practitioners who are interested in developing computational models of social information systems. We particularly welcome submissions from diverse disciplines, and we welcome and value suggestions about themes or directions of research related to this area. Please submit an 3-5 page research or position paper about your work. Papers will be reviewed and selected based on their relevance to the workshop and ability to contribute to the discussion. Email your paper, in PDF, to socialcog2010 at gmail.com with the subject line "CHI 2010 Cognitive Models Workshop? by December 15, 2009. Authors will be notified by January 10th, 2010. Papers should be in the ACM SIGCHI submissions format. If you have any questions please feel free to contact us by email directly.

As of right now we can execute a production in SS-RICS that will query the ConceptNet database and return declarative memory chunks depending on your assertion. So you can say something like Hammers LocationOf - which is basically a request to find where you are likely to find hammers, and a fact, of type concept, will be created with Hammer and LocationOf ToolBox as a slot. So you would know that hammers are found in tool boxes. We have worked hard to convert the ConceptNet database into something that is more "accessible" than what was originally provided by the Python interface. We have converted the database to SQL Server and that has helped tremendously. Hopefully we will publish something this year. Cheers, Troy D.

In most years, a summer school and workshop are organized at Carnegie Mellon University for training and discussion of the theory. This year, there will be a European version of these events in the Spring that we would like to develop in a yearly event if there is sufficient interest. There will be a four-day spring school, and a two-day workshop Spring School The spring school will take place from Monday April 12 to Thursday April 15. Participants have the choice between either following a compressed four-day version of the traditional summer school curriculum, or to carry out a project of their own with guidance from experienced ACT-R modelers. The latter option assumes some prior ACT-R experience, either through self study, or having followed an earlier ACT-R summer school. The standard curriculum is structured as a set of six units, of which we will do four in the course of the week. Each unit lasts a day and involving a morning theory lecture, an afternoon discussion session and an assignment which participants are expected to complete during the day. Computing facilities will be provided or attendees can bring their own laptop on which the ACT-R software will be installed. To provide an optimal learning environment, admission is limited. Prospective participants should submit by January 10 an application consisting of a curriculum vitae, a statement of purpose, and, if applicable, a description of the project they would like to do during the spring school. Demonstrated experience with a modeling formalism similar to ACT-R will strengthen the application, as well as general programming experience. Applicants will be notified of admission by January 20. European ACT-R Workshop The European ACT-R workshop will take place from Friday April 16 to Saturday April 17. The workshop will feature research presentations, discussion sessions and instructional tutorials. We still have to determine the exact structure of the workshop, so suggestions for the topics of the tutorials and discussion sessions are welcome. Admission to the workshop is open to all. Registrations fees and housing Spring School + Workshop: Euro 150 Workshop only: Euro 100 Late fee (registration after March 12): Euro 50 Housing will be offered in the university guest house for approximately Euro 60/day (single, double rooms are around Euro 75). Registration To apply to the Spring School, send and email to Niels Taatgen (niels at ai.rug.nl ), and attach the requested documents, before January 10, 2010.

It's a modeling convenience that was put into ACT-R 6.0 to address issues that people had using ACT-R 5.0, particularly with respect to the perceptual buffers. Keeping the chunk around was the less common action in most models and there were lots of explicit buffer clearings required in the productions. That was often confusing and required more work to get it "right". So, the clearing was made the default action instead. It can be turned off on a buffer by buffer basis with the :do-not-harvest parameter, and it can also be prevented in a production by using the buffer on the RHS (even without making any modification).

OK. So, I can assume that DM is a form of a Bayesian network. I am looking right now to determine its relationship to the basic Bayes theorem (as per Russell and Norvig, p 479): P(b|a) = (P(a|b)P(b)) / P(a) This may be just stupid probability theory math to some, but I would really like to understand it. It's important to me.

I found log likelihood in Bayesian networks on p. 716 in Russell and Norvig: AI--A Modern Approach, which describes the answer to my question almost in full. Surely, there has to be others who would want to know this. That this stuff is in Russell and Norvig may be helpful to many. Anderson reformed his Activation formula into a maximum-likelihood parameter learning problem that used log likelihood: Log[posterior(i|C)] = log[prior(i)] + Summation from for members j of C of the log[likelihood(j|i)] in which the components of his Activation formula line up with each piece of this formula respectively. That makes ACT-R a statistical inference method overall. There is more to read up on this in Russell and Norvig, but it seem this is a good starting point for those looking at ACT-R from a computer science perspective. A hearty thanks to Darryl for the reference he sent. Karri Peterson -------------- next part -------------- An HTML attachment was scrubbed...

Under the direction of Gerd Gigerenzer, one focus of ABC investigates how heuristics, that is computational models of simple cognitive processes, enable people to make effective decisions with limited information. The focus of LIFE is the study of systematic changes in human behavior over evolutionary and ontogenetic time. The student?s primary affiliation will be with ABC, an interdisciplinary group of psychologists, computer scientists, and evolutionary biologists, to name just a few of the disciplines represented. The Center provides excellent resources, including a laboratory run by professional staff, and generous travel support for conferences. The working language for both ABC and LIFE is English. [ www.mpib-berlin.mpg.de/en/forschung/abc www.imprs-life.mpg.de/ ] Lael Schooler is particularly interested in supervising students with interests in the cognitive mechanisms underlying decision making across the life course and that have a background in computational modeling, preferably in ACT-R. The ACT-R community strives for a coherent theory of cognition that can account for phenomena ranging from basic laboratory experiments on human memory to driving a car or controlling robots. [act-r.psy.cmu.edu en.wikipedia.org/wiki/ACT-R ] Applicants should hold, or anticipate receiving, a master's degree, Diplom or equivalent in a relevant field prior to the their preferred start date, which can be either April 1st or October 1st , 2010. Students admitted will receive a monthly stipend of about 1,100 EUR funded by LIFE. The initial fellowship is for 2 years and two 6-month extensions are possible. The deadline for applications is November 30, 2009. We strongly encourage applications from women, and members of minority groups. The Max Planck Society is committed to employing more handicapped individuals and especially encourages them to apply. For details about the application process, visit [ www.imprs-life.mpg.de/en/admission/howto.html ].
