It will be at Jake Melnick's Corner Tap at 41 E. Superior St. A map from the conference hotel is attached. It is a 1 mile walk. It looks like we are expecting about 35 people. This will be a wine, beer and cocktail event with hors d'oeuvres and socializing. We have a private room and a private bar. Hope to see all of you there. Cheers, Phil Philip I.

If one were walking, there is most certainly a more direct route and I think it is considerably less than a mile then. One should simply walk North on Dearborn to Superior, make a right heading toward the Lake and go to 41 E. Superior.

It is detailed in a paper I wrote with Hedderik van Rijn and John Anderson for ICCM-2004. I prepared a small webpage with the paper and the code. Unfortunately I have documented the code yet, but it should be relatively clear if you look at the paper. Here is the page: http://www.ai.rug.nl/~niels/temporal.html Good luck!

I've been trying to make this process easier on myself. However, I've quickly come to realize that this interfacing problem is one faced by all modelers regardless of architecture. In my conversations with the robotics folks at NRL, it's also become clear that they face a similar problem. As such, I'm proposing the formation of the CommonReality OpenGroup. What is it? It is a group that will work towards creating a general abstraction layer for architectures and devices to permit better interoperability across architectures, devices, hardware, and software. Participation is open to anyone interested. The goal is to produce reference implementations of this abstraction layer in all the primary modeling languages (not architectures, since this should be architecturally agnostic). These reference implementations can then be used by architecture and device developers to ensure reliable interactions. I have posted a power point presentation on the general rationale behind the open group as well as a prototype description to get people thinking and talking. http://sourceforge.net/projects/commonreality/ I ask that anyone and everyone who thinks they have a stake in this to participate. It will only work if we have a wide array of participants from numerous fields. This message is being cross-posted to the Soar and ACT-R lists. If you are aware of others who would be interested, please forward accordingly. =============================================== "The unexamined life isn't worth living; however, the over-examined life isn't living."

One good source of previously published papers is a double-symposium on the AMBR multi-tasking models from the 10th Conference on Computer-Generated Forces and Behavior Representation. These papers are available for download from the conference website by going to http://www.sisostds.org/ and following these links: Conferences and Workshops Conference on Behavior Representation in Modeling and Simulation (formerly CGF) 10th CGF-BR View Papers and Presentations The papers are organized by paper number. You are looking for papers 66-74. There are a variety of other conferences at which AMBR papers have been published/presented in the last few years. Unfortunately, most conferences don't put their content on a public website. I am attaching a complete set of AMBR references as a resource for those seeking more material. Additionally, we have a book in press with Erlbaum. The copyeditors are working it over right now and it should be available publicly mid-year next year. Here is the reference: Gluck, K. A. & Pew, R.

I believe that this is an important project for the following reasons: 1. In theory, all knowledge starts as declarative and is compiled into productions. Since step by step instructions and other forms of process knowledge are a key part of the knowledge an expert brings to any task, ACT-R needs to have some way of representing, executing, and proceduralizing this sort of knowledge. ACT-R has a mechanism for proceduralization (admittedly an incomplete and evolving one, but there is a mechanism) but the Tutorial Appendix is the only mechanism I know of for executing declarative process knowledge (i.e., rules). 2. In my domain (accounting), experts rarely have sufficient practice at any task to proceduralize their knowledge, at least the higher level knowledge. Clearly, high-order knowledge contains primitive components that are highly practiced (like basic math skills), but accountants constantly face new issues that require working through declarative structures to resolve. In addition, they always need to explain their actions and, therefore, are constantly using declarative representations of process knowledge (since procedural knowledge is unavailable for explanation except if the expert observes their own actions and then retrospectively infers the procedural knowledge used). Finally, administratively, managing large production systems is very difficult in ACT-R. I need to manage large knowledge bases to properly model my subjects. Declarative knowledge is much easier to manage because it fits into a relational database structure very nicely. I am building an Access database to manage chunks. The database will merely produce a text file with the "add-dm" and "chunk-type" statements needed to feed the information into ACT-R. The system will also be able to track links between productions and chunks through the chunks embedded in the productions slots in the same way ACT-R instantiates productions, which should help manage the productions as well. It would add the "P" statements needed to feed productions into ACT-R as well. This will give me a very powerful tool to sort, select, edit, and display chunks and productions is just about any way I want to. I haven't progressed too far with the database side because I need to build more extensive, generic, productions in ACT-R to work with declarative knowledge, particularly process oriented declarative knowledge. That is, before I build a massive database, I need an ACT-R system that can handle it. If you are working on a similar project(s), or know of someone who is, I would love to hear from you. There are no other ACT-R researchers at the U. of Maryland and so I could use someone to talk to. Thanks. Jim James M. Peters, Ph.D. Department of Accounting and Information Assurance R. H.
