13:49:22 RRSAgent has joined #decision-xg 13:49:22 logging to http://www.w3.org/2010/09/30-decision-xg-irc 13:50:01 piotr_nowara has joined #decision-xg 13:50:19 Meeting: #decision-xg 13:50:48 chair: Jeff Waters and Don McGarry 13:51:08 Agenda: http://www.w3.org/2005/Incubator/decision/wiki/Decision_Mtg_14_Agenda 13:51:21 Scribe: Jeff Waters 13:51:37 ScribeNick: jeffw 13:52:26 eblomqvi has joined #decision-xg 13:57:13 jeffw: Hi, Piotr and Eva! 13:57:19 hi 13:57:33 jeffw: We have Marion on the telephone as well. 13:57:43 I am calling in now 13:57:55 hi 13:58:42 jeffw: This is a fun time for our incubator, since we have a nice position paper which Eva has wonderfully edited and prepared for the Workshop on Ontology Patterns for ISWC 2010. 13:59:26 jeffw: Piotr, will you be able to join us on the phone as well? 14:00:36 i'm trying to make a call 14:00:37 jeffw: Thank you Eva for you edits and fixes for the work. 14:00:50 it seems that the french line doesn't work 14:01:14 eblomqvi: Jeff, will you be able to provide some input? 14:01:34 jeffw: Yes, I'll be able to provide the inputs you requested. 14:04:12 i've joined the teleconference 14:04:24 jeffw: I thought the reviewers liked the topic, and appreciated the readability, but in some ways wanted more. 14:04:51 eblomqvi: I had a related topic, regarding the agenda, and there was another opportunity for a practical exercise in the workshop trying to produce some patterns. 14:05:19 eblomqvi: We have a call for proposals for things to work at the workshop and I suggested we had some modeling problem to submit to the workshop 14:06:03 eblomqvi: I found an old email where Jeff listed some ideas that we've encountered that might be worth submitting, like the metrics issues and a few others. 14:06:54 eblomqvi: The deadline is also tomorrow, if you would like to proceed it's not a huge effort to submit to the patterns portal as a suggestion, if it happens to get selected, it could be helpful and nice opportunity to see what would come out of it. 14:07:21 eblomqvi: In case you are interested, I could try to describe one or two of these problems and we could see if we could submit by tomorrow. 14:07:45 marion: That sounds like a great idea. I have a question about the page limit, is it 4 or 5? 14:08:14 eblomqvi: it is 4, so I will still need to cut it down tomorrow afternoon, so the deadline I gave you was a little early. 14:08:27 marion: I could look through and make suggestions for cutting. 14:10:58 jeffw: Yes, and I agree that we should submit some problem, there is 14:11:06 topic: Paper status and remaining fixes 14:11:58 jeffw: so we've been discussing that, did anyone else have any comments? 14:12:24 marion: I have some suggestions, but it would help if I could work from a version I could edit 14:12:57 eblomqvi: You can edit in a plain text editor, the latex file, you'll see some strange sequences but you can at least edit the plain text 14:13:18 eblomqvi: You should be able to edit with notepad fine. 14:15:06 eblomqvi: We can use Word next time, I just started writing while people were on vacation, but if we can survive for now, we'll figure it out better next time. 14:15:28 topic: Modeling a Question as a Statement with Variable, Referencing using Quads, and rdf:Sequence for Options 14:16:54 jeffw: ok, one pattern that occurs in the options is an ordered list, so one issue is how best to represent an ordered list 14:19:33 jeffw: Is there a problem with using rdf:Sequence for an ordered list? I know there are other solutions for modeling ordered lists. 14:20:14 eblomqvi: It's similar to problem of named graphs, you want to talk about it and be on the modeling level rather than the data level, I think I sent you this link once before 14:20:38 eblomqvi: but I will post again, so it's one of the solutions for how to model this in OWL. So I will post this link for you. 14:20:44 http://swan.mindinformatics.org/spec/1.2/collections.html 14:21:07 jeffw: Just the existence of other solutions suggests there may be problems with the rdf solutions. 14:22:42 eblomqvi: rdf solutions are just talking about the data, but if you want to say things about the constructs of the list that's the main difference 14:23:01 jeffw: ok, I see that, that insight will help me think about it. 14:23:15 the link I posted above is one suggested solution for modelling sets, bags and lists 14:23:39 jeffw: Piotr, do you have a preferred solution for ordering? 14:24:06 piotr_nowara: I found this solution that Eva found, but I don't have a preferred solution. 14:29:05 jeffw: named graph issue, I wanted to use the concept of question as a component of a decision, so I found the quads and named graphs as the better solution, any thoughts? 14:30:17 eblomqvi: re provenance, it is the same sort of problem, it seems like people are heading in this direction as opposed to reification, we are going in the direction others are 14:32:02 piotr_nowara: modeling questions, questions can be modeled as a statement, so you're statement with variable idea, 14:36:11 jeffw: For how to model this, I was thinking about a variable class, then subclasses like who, what, where, when and then perhaps subclasses like whatComputer, whatCity 14:36:23 marion: consider upper ontologies, that would be a good idea 14:37:05 eblomqvi: There are different types of question, if you ask who, it should be of type Person, if where, then of type Location, so we could look at question/answering literature, maybe I could have a look and pull some links 14:39:33 jeffw: Yes, I'd very much anything you can find and it could be posted to the wiki or whatever. That would help me. 14:40:04 marion: we need to understand what and how and why we are answering the question 14:40:49 eblomqvi: if you really want to do question/answering, we won't necessarily get the correct answer, like weighing options, we are not necessarily finding THE answer as much as allowing for uncertainty 14:41:13 marion: You have to allow counter-factuals or else you can't consider the options appropriately. 14:41:20 jeffw: Can you give me an example? 14:42:05 marion: it's a what-if question, it poses as a proposition, it suggests a situation that isn't true and then reasoning on that to see what would be if it were true 14:43:48 jeffw: yes, I like your idea, and it goes beyond what I was describing, i wanted a way to point to a machine understandable version of a question and you are suggesting going beyond so that it points to a machine understandable version of a question that can help you actually come up with a solution 14:44:33 marion: you could consider the outcome, have the computer rank order based on pre-set, etc. 14:45:34 marion: What could exist now v. what could exist if other things occurred and there is secondary issues like cognition under stress and it seems to me this is doable 14:49:03 marion: if you could indicate this is a question, then if no known domains refer to it, then you could consider how to incorporate 14:49:29 topic: Update and Insights on "Core Decision" Model Issues for Decisions 14:50:41 piotr_nowara: I'd like to discuss the issue about the question, I'd like to suggest introducing a boolean variable that some questions like Should I buy this kind of computer where the answer is yes/no 14:51:10 piotr_nowara: so we should consider this type of variable. 14:52:21 eblomqvi: for the other core decisions model, I promised to answer the e-mail and I haven't, but I got some of the discussion with some interesting points, the notion of a situation could be used to model criteria etc. and I did'nt have a chance to think hard on this 14:52:46 eblomqvi: but I should have more time in the coming week, piotr would you like to recapture your thoughts on criteria? 14:53:48 piotr_nowara: I need a couple days to explore my criteria pattern and how they are related, to summarize, I think criterion is a point of reference by which we can evaluate, and it is determined by something, like a regulation or constraint that sets some criterion, a criterion center 14:54:30 piotr_nowara: but determining the domain .... (I think we lost the connection) 14:55:25 eblomqvi: I am very interested to see your progress on this criterion pattern, I'd be happy to see it even if not the final version and we could learn and utilize 14:58:23 piotr_nowara: the requirements determine which domain for which the criteria is valid, there is a yes/no but there is the quality of SQL knowledge, so the situation pattern could be used to express that domain connection, should we introduce the broader concept of the criterion 14:58:43 piotr_nowara: or should we just do a simple pattern 14:59:16 eblomqvi: Piotr, I would suggest you do both, cause we could take a modular approach, you could do the basic pattern and in a more detailed version, you expand, would that work? 14:59:32 piotr_nowara: I like that idea and I'll let you know when I have some results 15:00:38 topic: Status of Web-based Tool for Decisions with Linked Open Data 15:04:54 jeffw: The concept of the tool is that you might begin with a question, like "What city should I vacation in?" and you could have some keywords, like "vacation" and "city", and these keywords could drive a search for relevant linked open data sets. 15:05:30 jeffw: Once those datasets are listed, you could browse them to see which one or more might be relevant and you pick one (or more) 15:06:36 jeffw: Then the items in that dataset become your options, for example "cities", and the properties of that dataset, e.g. population, number of museums, etc., become the potential criteria. 15:07:26 jeffw: you then pick the properties you want for the criteria, how you want to weight them and any min/max threshold, such as population < 300,000 with a weight of 1.5 15:08:13 piotr_nowara has left #decision-xg 15:08:22 jeffw: then the criteria are applied to the options both to filter out options which don't fit the boundary conditions, but also to order the options based on the criteria and its weight, assuming the criteria can all be quantified and normalized for comparative purposes. 15:09:06 jeffw: Then you make your decision based on the reordered options. All of this is captured in our decision format including the amount of time spent in which states of the decision process. 15:09:44 jeffw: That's the concept and I'll ask our tool developers to see if they can join us next time to discuss this in more detail. 15:09:57 jeffw: Thanks everyone for calling in.
