The term "studies" in the above text seem to refer, most naturally, to controlled experiments, though, plausibly, it could refer to longitudinal or case studies, or perhaps user surveys. > Thanks for saying the idea is elegant. Hopefully, studies such as > [1,2,3] are building evidence that it is also useful. [snip] The "studies" cited in this subsequent text do not seem to fall into any of the paradigms I mentioned. One could, perhaps, stretch, and call them case studies, though, as such, I do not find them especially illuminating. Perhaps it's best to call them "worked examples". The first (<www.reengineeringllc.com/ Oil_Industry_Supply_Chain_by_Kowalski_and_Walker.pdf>) is perhaps more of a system description or white paper with a worked example embedded. Furthermore, it does not seem to me that there is an active research program, at least. I'm pretty sure I read the first article some time ago, and the second examples have the strings "Version 20041215" and "version 20041029" which strongly suggests that they are from 2004 (I also recall seeing these or similar from at least that time frame). I recall an email thread twixt me and Adrian wherein he explicitly said that he didn't have formal studies: http://lists.w3.org/Archives/Public/public-sws-ig/2005Jul/0007.html """The problem can get worse with rule systems, if we stick to the techie notations that us techies know and love. Or it can be mitigated, if we make sure that the person writing the rules has to document what they mean at the real world business level. If this is done by including lightweight English in the rules themselves, the rules and the documentation cannot get out of step. We can also get English explanations of the reasoning. We don't yet have HCI studies to say whether this is a good approach. As you said elsewhere in your posting, such studies are hard to do, and sometimes inconclusive. However, a system** that supports the approach is live, online. So, one can get an idea of the 'value proposition' (ouch!) by viewing and running the RDF and other examples provided. One can also use a browser to write and run one's own examples. Non-commercial use of the system is free."""" (Note, that this was specifically in the context of the need for explanations, and explanations in NL.) I don't mind advocacy, and often proof is in the pudding and the proving is in the eating. I personally am happy to document my own idiosyncratic and native speaker reactions. But can we *please* not pollute the discussion space with such misclassification and hyperbole? In either direction? (E.g., Pat's skepticism about NL/CNL techniques also carries no water with me and I *am also* suspicious, by inclination, of NL/CNL techniques!). I know four things in this area: 1) our pilot study was surprisingly promising for understanding (so, search results; verification by domain experts, etc.) 2) someone reported using Swoop's NLP view for verification and even correction by domain experts (that last part I don't understand quite as we don't provide a parser) 3) I know that there are ontology building teams that make use of stilted NL toward CNL as a core part of their methodology with crappy tool support 4) Some users have expressed some happiness at Manchester syntax, though there have been reports that it's still "too logicy" I thought the last was mentioned by the presenter of this paper: <http://owl-workshop.man.ac.uk/acceptedLong/submission_30.pdf> (Which is well worth reading, folks! And it includes a study study :)) But I cannot find this in the paper itself. So I'm unsure about 4. (The paper is a good reminder that, well, our tools suck. I say this as a toolbuilder! I can see places in the paper where I can predict how swoop would do, and it's not pretty :) Sigh. I mostly know, I think, how to fix a lot of it, but it's also true that Swoop was not designed for "normal" users. Though I don't know how "normal" the users are if they are comfortable in an Eclipse based environment :)). Cheers, Bijan.
