There is today wide agreement that knowledge modeling and the semantic dimension of information plays an increasingly central role in networked economy: semantic-based applications aim to provide a framework for information and knowledge sharing, reliable information exchange, meaning negotiation and coordination between distinct organizations or among members of the same organization. Often, theoretical ideas seem very promising but their actual implementation brings up unexpected problems and issues. The FOMI 09 Workshop aims to collect useful experiences and lessons learned by the presentation of (1) experienced problems in ontology application, (2) new insights on known problematic issues, (3) new results and observations in ontology implementation, (4) lessons learned on the best way to apply ontological methodologies to real situations. FOMI 09 will facilitate open discussion and experience sharing. Very similar problems arise in disparate ontology applications and an open discussion helps to highlight commonalities and to spread ideas for possible solutions. For this reason, FOMI welcomes researchers and practitioners that embrace this perspective without restrictions on the domain they deal with: business, medicine, engineering, finance, law, biology, geography, electronics, etc. CONFERENCE TOPICS (not exhaustive) *problems in ontology application:* - practical issues in using ontologies in the enterprise - real cases of successful/unsuccessful use of ontology in business - from legacy systems to the new ontology-driven systems *ontology and knowledge management:* - ontology and ontological methodologies in knowledge management; - adaptation of ontologies for companies and organizations; - ontology development and change within organizations; - ontology effectiveness and evaluation - ontology-driven representation of products, services, functionalities, design, processes; - ontologies for the know-how; - ontologies for corporate knowledge; *ontology in practice:* - ontologies for electronic catalogs, e-commerce, e-government; - ontologies for marketing; - ontologies for finance; - ontologies for engineering; - ontologies for medical sciences; - etc. SUBMISSIONS AND DATES Submitted papers will be reviewed by at least two member of the Program Committee and selected on the basis of technical quality, relevance of the described experiences, and clarity of the presentation. In particular, we insist that papers should (1) be written for a wide audience and (2) focus on the problematic, successful, etc. ontological aspects. Following the previous FOMI editions, we are considering publishing the proceedings of the workshop in the FAIA series (IOS Press) or as a special issue of "Applied Ontology". * Format and other information will be added in the conference website shortly. * Deadlines: - Paper Submission: April 2, 2009 - Acceptance Notification: May 23, 2009 - Camera Ready: June 23, 2009 ORGANIZING COMMITTEE Chair: Roberta Ferrario, Alessandro Oltramari - Laboratory for Applied Ontology (ISTC-CNR), Trento - Italy.

However, it does not provide a capability to change the type of the chunk to which the slot is added in the process. This is problematic in that new slots added to an existing chunk cannot be referred to in subsequent productions, since the chunk type is inconsistent with the existence of the new slots. To see where this causes problems in a model of language processing, consider the case of verbs like "sneeze" which typically occur in sentences like "she sneezed" where they project intransitive verb constructions. Such verbs occasionally occur in larger "caused-motion" constructions as in "she sneezed the napkin off the table" (this is an important area of research in Construction Grammar). If the processing of the verb "sneezed" leads to projection of an intransitive verb construction, then when "the napkin" and "off the table" are processed, there will be no slots in the intransitive verb construction into which these constituents can be integrated. Using P* productions, slots can be created for integrating "the napkin" and "off the table" into the intransitive verb construction. However, in subsequent processing, these new slots cannot be referenced since they aren't part of the chunk type definition for intransitive verb construction chunks. Currently, the only way I know of to handle this in ACT-R 6 is to create a new chunk type "caused-motion" which contains the extra slots when "the napkin" and "off the table" are processed, and then copy all the slot values from the intransitive verb construction to the new caused-motion construction in addition to integrating "the napkin" and "off the table" into the new chunk. It would be computationally simpler to just add the slots to the intransitive verb construction and change the chunk type to reflect the additions, i.e. to caused-motion in this example. Besides being computationally simpler, there are other reasons for preferring this approach. If the intransitive verb construction is integrated into a larger linguistic unit, then when the new caused-motion construction is created, all references to the intransitive verb construction must be tracked down and replaced. For example, in "she sat down and then she sneezed the napkin off the table" if the intransitive verb construction projected by "sneezed" is integrated as an argument of the conjunction "and then" prior to the processing of "the napkin" and "off the table" (as in the current model), then it will be necessary to replace the reference to the intransitive verb construction with the reference to the caused-motion construction. In general, this may require significant processing effort. Although important in Construction Grammar, the use of an intransitive verb like "sneezed" in the caused-motion construction is fairly uncommon. However, the need for a capability to dynamically add slots to and adjust the chunk type of a chunk is actually quite pervasive in language processing. Consider for example, ditransitive verbs like "give". There are two distinct ways in which ditransitive verbs are used, with an indirect object as in "he gave me the book" and with a prepositional phrase argument as in "he gave the book to me". At the time the verb is processed, which form will actually occur is undetermined. Currently in our language model, a verb like "gave" projects a ditransitive construction which contains slots for both an indirect object and the "to" prepositional phrase. This allows the model to handle both forms without having to create new chunks on the fly for each case. With an ability to dynamically modify chunk types after adding needed slots, the model could project the more likely chunk type given the context and frequency of use (i.e. either indirect object or "to" prepositional phrase") and still handle the alternative form when it occurs, rather than having to provide slots for both possibilities in a single construction. To support subsequent processing, we would like the chunk type to accurately reflect the chunk. To the degree that this is not the case, problems are likely to result. Verb-particle compounds which are ubiquitous in English, provide another example of the need for this capability. If the input is "he looked...", what construction should the verb "looked" project? According to Longman's dictionary, the most common use of "look" is in combination with "at" as in "he looked at the book", but "look" also occurs in combination with an adjective as in "he looked happy" and with a range of different particles as in "look up", "look over", "look for" where the meaning of the expression depends on the combination of "look" and the preposition--indicating storage of these verb-particle combinations as a unit in the mental lexicon. Besides needing to store verb-particle combinations to determine meaning, the argument expectations vary with each combination. Thus, we can say "he looked up" or "he looked it up" or "he looked the name up" or "he looked up the name" (and in spoken language "look it!" is becoming more and more common) but not "he looked it at" or "he looked the book at". To handle all these possibilities, some kind of accommodation mechanism is needed which does not involve backtracking and is unlikely to be a repair mechanism--given the ease with which humans process such variability. At the processing of the verb "looked" the model should project the construction which is the best candidate given the current context and prior history of use, but the model must be prepared to accommodate the subsequent input. Humans appear to be very good at handling this kind of variability, typically being unaware that there are multiple possibilities at each choice point. The ability to add slots to existing chunks using P* productions, combined with a capability to dynamically adjust the chunk type of the resulting chunk appears to provide just the needed capability. The alternative of having to project new chunk types and copy over slot values and adjust preceding references requires more computation than is likely to be consistent with human language processing of such inputs. More generally, such a mechanism would give ACT-R a functionally motivated capability to create new chunk types, providing a learning mechanism that appears to be needed to support the learning of new construction types during language acquisition. If children do not come with a full construction ontology built in, then some mechanism for extending previously learned constructions to novel constructions is needed. Allowing for the addition of slots to existing chunks, combined with a capability to modify the chunk type--when the linguistic input warrants it--perhaps creating a new chunk type in the process, would provide just such a mechanism.

It is in fact possible to access slots which have been added to a chunk via a p* through other productions. The key to doing so is that either those slots must be accessed via the abstractions in a p* or the production must be created after the slot has been added to the chunk-type. Attached is a simple example showing both situations - a production accessing a newly created slot of a chunk in a test through p* and a production which gets learned via production compilation specifically referring to a newly created slot. It's not an elegant model, but it does show that new slots can be accessed and directly incorporated into productions. What I'm not quite getting is why you need to be able to access those slots in productions which you're writing. If you know what those extra slots are to write them into a production why can't you just put them into the chunk-type definition up front? There is essentially no penalty for a chunk having "extra" slots which are empty and it is possible for chunk-types to be structured in a hierarchy so that you can have general as well as specific productions handling things. The question I have is how does changing the chunk-type actually solve the issue? How could you write productions which referenced the new chunk-type unless you also knew its name and in fact all of its slots in advance, and if you know that, why do you need p* to create the slots? I'm not saying that I oppose such a mechanism, but I'm just not sure what exactly it solves and how exactly it's intended to operate.

Thanks for the sample code! One question -- your second example using production compilation leads to creation of a regular production (not P*) called PRODUCTION1 that references the "new-slot" of the "content" chunk in the imaginal buffer. Since this is not a P* production and the "new-slot" slot name is not passed in as a variable via the goal chunk as in the first example, it doesn't seem like this production should work. Am I missing something? With respect to creating new chunk types, it is true that a mechanism for creating productions capable of processing the new chunk types would also be needed. Our primary use would be to specialize a chunk into a pre-defined chunk subtype consistent with the added slot(s). With respect to having "extra" slots, there are a couple of reasons for not wanting to have "extra" slots in chunks to handle all the possible construction forms: 1) these "extra" slots can interfere with subsequent processing by matching to productions when they shouldn't (i.e. we'd like the "extra" slots to be restricted to appropriate chunk subtypes), and 2) in general, it is not possible to handle all the possible construction alternatives in a single construction, nor is it desirable. For example, the verb "give" also comes in verb-particle constructions like "give up", "give in" and "give out" in addition to the normal ditransitive forms. Trying to create very general chunk types with lots of slots to handle all the possibilities would dilute the constructions in inappropriate ways. For example, having slots for arguments like "the napkin" and "off the table" in the case of constructions for intransitive verbs like "sneeze" in order to handle the special (an infrequent) caused-motion use, would effectively eliminate the concept of an intransitive verb. And if modifier (or adjunct) slots as well as arguments slots are included in construction chunks, then the number of such slots in undetermined (e.g. "he hiked up the hill, over the top, down the back, thru the woods..."). In fact, in the case of modifiers, we may want to add slots to a construction chunk without (essentially) changing the chunk type. The model currently makes extensive use of chunk types organized into a chunk type hierarchy. In general, the more specific the chunk type in a buffer that matches a production, the higher the utility of the production. It is to take advantage of this capability that we would like to have specialized chunk types. If a new slot is added to an existing chunk (based on the input) and the type of that chunk is specialized to a more specific (pre-defined) chunk type as a result, then productions matching the specialization can fire and are likely to lead to better representations.

So, you may be able to add new modules or modify ones which you have to do this and see what you get. A buffer modification request in a p* will (now) pass arbitrary slot names to a module and the module can do whatever it wants to the chunk in the buffer including overwriting it with another chunk of any type. I'd recommend the overwrite so as to not flush the 'incomplete' one to DM. The qualifiers of almost and now above reflect that priory to r732 there was actually a validation test which would prevent a module from doing that, but if you checkout the most up to date sources you can do what's described there with p*. Below is a stub of a module which uses a buffer modification request to create a new chunk for a buffer of a fixed type and slots which are all predefined. It doesn't copy any of the slot values from the chunk currently in the buffer, but that wouldn't take too much more to add. There's also an extremely simple model which uses that along with a trace of it running. So, you should now be able to try something like that out with your own modules to see if it gives you what you need.

To remedy this situation, Information Reuse and Integration (IRI) seeks to maximize the reuse of information by creating simple, rich, and reusable knowledge representations and consequently explores strategies for integrating this knowledge into legacy systems. IRI plays a pivotal role in the capture, representation, maintenance, integration, validation, and extrapolation of information; and applies both information and knowledge for enhancing decision-making in various application domains. This conference explores three major tracks: information reuse, information integration, and reusable systems. Information reuse considers optimizing representation methodologies; information integration studies strategies for creatively applying models in novel domains; and reusable systems focus on ontological opportunities for deploying models and corresponding processes. The IEEE IRI conference serves as a forum for researchers and practitioners from academia, industry, and government to present, discuss, and exchange ideas that address real-world problems with real-world solutions. The conference feature contributed and invited papers. Theoretical and applied papers are both included. The conference program will include special sessions, open forum workshops, and keynote speeches. A forum will be conducted with the intent of bridging IRI and Systems of Systems and why the future of intelligent computing - including computing applications - will lie at the juxtaposition of these two topical areas. There will be new IRI Society Memberships and Awards. The conference includes, but is not limited to, the areas listed below: - Large Scale Data and System Integration - Component-Based Design and Reuse - Unifying Data Models (UML, XML, etc.) and Ontologies - Database Integration - Structured/Semi-structured Data - Middleware & Web Services - Reuse in Software Engineering - Data Mining and Knowledge Discovery - Sensory and Information Fusion - Reuse in Modeling & Simulation - Automation, Integration and Reuse across Various Applications - Information Security & Privacy - Survivable Systems & Infrastructures - AI & Decision Support Systems - Heuristic Optimization and Search - Knowledge Acquisition and Management - Fuzzy and Neural Systems - Soft Computing - Evolutionary Computing - Case-Based Reasoning - Natural Language Understanding - Knowledge Management and E-Government - Command & Control Systems (C4ISR) - Human-Machine Information Systems - Space and Robotic Systems - Biomedical & Healthcare Systems - Homeland Security & Critical Infrastructure Protection - Manufacturing Systems & Business Process Engineering - Multimedia Systems - Service-Oriented Architecture - Autonomous Agents in Web-based Systems - Information Integration in Grid Computing Environments - Information Integration in Mobile Computing Environments - Information Integration in Ubiquitous Computing Environments - Systems of Systems - Semantic Web and Emerging Applications - Information Reuse, Integration and Sharing in Collaborative Environments Instructions for Authors: ------------------------- Papers reporting original and unpublished research results pertaining to the above and related topics are solicited.
