10:21:21 guus: wordnet isn't a conventional thesaurus 10:21:26 Guus: Wordnet is not a thesaurus in the ISO sense 10:21:26 ...nor mesh 10:21:38 ....but in the library world, ppl have been making thesauri for ages 10:22:39 ralph: can we target a specific thesaurus? 10:22:48 aharth has joined #swbp 10:22:49 al: sure. we already have gemmet(?) who use a prev version of skos 10:22:53 ...also uk govt categories 10:23:34 ... in swad-e we did a cycle of review/test/etc 10:24:04 ralph: i didn't realise it had been used, wasn't clear from the docs 10:24:09 al: is linked from the swad-e pages 10:24:26 http://www.w3.org/2001/sw/Europe/reports/thes/ 10:24:56 usecases: http://www.w3.org/2001/sw/Europe/reports/thes/usecase.html 10:25:02 DanBri: the Digital Library community likes this because RDF allows them to use many representation types and specialize 10:25:18 ... worries me because of a view toward "facet modelling" 10:25:28 ... I think they don't realize what can be done with OWL 10:25:47 ... in the RDF & OWL world we can say "subClassOf" 10:26:06 ... in the thesaurus world they are accustomed to want to say 'broader' and 'narrower' 10:26:22 Al: SKOS attempts to not replicate things that are already in OWL 10:26:35 DanBri: 'denotes' relationship bridges models 10:26:35 PhilT has joined #swbp 10:26:50 http://www.w3.org/2001/sw/Europe/reports/thes/8.8/ 10:27:17 ... subtle distinction between modelling in RDF and OWL over modelling thesaurii -- will be important for us to explain thi 10:27:24 s/explain thi/explain this/ 10:27:25 al: of whole skos core vocab, the broader property is the most important one in there 10:27:49 david: al, you said the thesaurus community only recently thinking beyond print... can you expand? 10:27:55 ...what are the changes? 10:28:16 al: single biggest impact of that, working in the print community, you have a thesaurus which is a book, terms, record cards... 10:28:26 ...you fill terms from thesaurus into record card 10:28:29 ...so term-centric 10:28:34 ...as people working with this 10:28:59 ...a problem with that, 'cos in a thesaurus you have two kinds of term, preferred descriptors and non-preferred terms 10:29:07 ...a descriptor is a main label for a concept 10:29:38 al: ...so confounding of term as unique id vs usage in natural language 10:29:45 david: i'm with you ... but ... so what? 10:30:00 al: althought a thesaurus is supposed to be concept oriented, in practice it is term oriented 10:30:19 WN draft might be : http://www.w3.org/2001/sw/BestPractices/WNET/wordnet-sw-20040713.html 10:30:34 guus: all these communities have built vocabs, they're v domain specific, terms represent agreements within a community 10:30:59 ...if people commit to this particular terminology 10:31:18 q+ to note comment from Brad @ Siderean 10:31:23 q? 10:31:27 al: as we move into networked world 10:31:32 Guus, ok to use zakim q? 10:31:48 Guus: even within a community there will be conflicts and disagreements in usage 10:31:55 al: where two vocabs collide in networked world, this is a new problem/issue to pre-electronic version 10:31:55 sure! 10:32:14 david: can you make that explicit in the document 10:33:14 action: aliman make explicit in skos core doc the fact that you're trying to deal with potential for multiple thesauri using the same terms, overlap etc., different from paper publishing world 10:33:27 Steve: this is an area in which Published Subjects might be helpful 10:33:30 steve: some relationship to published subjects 10:33:52 guus: not sure ... that this is specifically work for this tf 10:34:29 ...happy to see port tf to propose a skos-based convention for represnting real-life thesauri in rdf/xml 10:34:31 ...could be very short 10:34:56 ...my main problem is ?size of doc / quickstart / primer 10:34:57 q? 10:35:14 ack danbriscribe 10:35:14 danbriscribe, you wanted to note comment from Brad @ Siderean 10:35:42 phil: you're looking at having multiple independent domain specific thesauri, but not at detailed cross domain mappings 10:35:51 Phil: are we looking at the problem of translating across domains; e.g. medical to something else? 10:35:59 Alistair: that's part of SKOS Mapping 10:36:16 DanBri: faceted browser for Dublin Core was built using a term-centric approach 10:36:38 ... the developer said the term-centric approach was easier to deal with, though less elegant 10:37:03 ralph: this discusssion positions what you've done better for me, in space of problem we're trying to solve. 10:37:08 JeffP has joined #swbp 10:37:28 ...is particularly important to emphasise the point that guus just made, perhaps in skos core guide, that the motivation be given right up front... 10:37:34 ...with examples 10:38:02 ...there's a risk that community rivalry might project from perceived qualities of a thesaurus to skos itself 10:38:06 ...so show several! 10:38:14 q+ to mention semantic blogging use case 10:38:24 ...so skos would be more persausive if described this way 10:38:46 ...so important distinction, between basic thesaurus representation versus fancy stuff on mapping 10:39:13 ...get basics out asap, showing some use for thesaurus world without getting bogged down in mapping 10:39:40 phil: suggesting that words on these constraints needed in the doc? 10:39:55 ralph: not sure we need to write it that explicitly, just make sure we work through real use case examples 10:40:03 ...by implication this shows our priorities 10:40:12 jjc: felt to me that al's later examples could have been more prominent 10:40:22 ack ralphs 10:40:22 RalphS, you wanted to comment about use cases 10:40:32 guus: i was visiting sound and vision institute 10:40:38 ...tv and radio archive of the netherlands 10:40:42 ...dutch 10:40:56 ...simple textual file, i just want to have a document to give them, to translate that 10:41:08 ...simple use cases are there 10:41:23 ...another one, dutch royal library, GOO (general object something) 10:41:30 ...v simple, uses 3 or 4 things from skos 10:41:38 ...term, broader term, related, ... 10:41:59 ...give them something to allow their developers something to build an rdf representation 10:42:06 ralph: so speed is important? 10:42:20 al: totally agree; with skos-core guide, as short and simple as possible, ... 10:42:40 [libraries-> web not sw; blogs, instances] 10:42:48 al: suggestions welcomed 10:42:54 danbriscribe, you wanted to mention semantic blogging use case 10:43:21 DanBri: several things going on here; lots of historical context for wanting to help migrate things to Semantic Web 10:43:33 ... librarians want to see their role in Sem Web 10:43:47 ... many cheaper and scruffier examples being generated 10:43:56 ... SKOS is interesting because it is right in the middle 10:44:11 ... it fits with the light-weight data sharing things like FOAF but it also fits into the library world 10:44:36 q+ to suggest standard use case scenarios across SWBP work 10:44:37 ... I'd like to see 2 classes of examples; a dump syntax for thesaurii and syntaxes that mix into the rest of the RDF world 10:45:14 ... with the move from print to electronic, what's changed in the library world is how they operate 10:45:29 ... there now are blog operators that create thousands of categories that point to a page 10:45:49 ... hierarchical categories in SKOS have been shown to work nicely 10:46:11 ... can now show to the library world that their work on thesaurii can show up in this new blog category world 10:46:25 phil: a point about pragmatics 10:46:35 ...a solution space for semantic tech for library world 10:46:46 ...as they're potentially an early adopter, could be some pain there 10:46:56 ...is it within our remit to help with take up 10:47:18 ...? there's some responsibility within this team to act as a reference point, or respond to, frustrations from early adopters 10:47:23 ...is that a wg responsibility? 10:48:08 david: this is our constant problem. charter is v broad. i wouldn't say that it is the wrong thing to do. potentially too hard for the group as it currently stands. 10:48:29 ...we could do less of something else we're doing, or else find someone out there to help with this 10:48:38 q+ to mention EU projects, IG, public-esw-thes 10:48:48 q? 10:49:07 phil: from my standpoint in industry, when you're trying to become an early adopter of this technology, BP seems to be an ideal home for channeled frustrations 10:49:10 jjc: i disagree 10:49:23 david: a pain registry would be good in theory... 10:49:38 ...but because i'm sensitive to what this group is being asked to do 10:50:03 danbriscribe, you wanted to mention EU projects, IG, public-esw-thes 10:50:26 DanBri: the people who participate in WGs are not generic reassignable resources; they have some role in their host organization 10:51:07 ... for example, those of us funded by EU are here to create supporting materials 10:51:50 ... when this goes out to WD, the WG has the responsiblity to respond to public comment 10:52:49 ralph: wg charter is, for better/worse, v broad 10:53:02 ...i view the intent of the charter of this wg to help the real world use the sw tech 10:53:06 ...migrate to it, etc 10:53:21 ...we can't afford to take on every user community whose pain we feel 10:53:36 ...but we should be confident that everything we work on addresses some genuine user community problem 10:53:54 ...what i've been pushing here is for the materials that we deliver to show the real world problem that is being addressed 10:53:57 q? 10:54:10 ...depending on the prob, we may or may not be able to demonstrate we solved it all 10:54:21 ...so be clear about what probs we want to be seen as solving 10:54:41 ...agree w/ phil that some of that is needed, but also +1 david's point re resource limitations 10:55:46 david: ralph likes to (rightfully I think!) pick up the concept of use cases... If a discussion comes up, Ralph will remind us to define a use case, also in document review. This is a really good idea. When we talk about what use cases we're going to do, the same short list comes up 10:56:13 It's always FOAF and DOAP 10:56:22 [DOAP vs DOPE] 10:56:27 ...drug ontology thing 10:56:40 ...we have a short list of a common candidates for use cases 10:56:56 DOPE: http://www.informatik.uni-bremen.de/swc/dope.htm 10:56:59 ...if we use same list across all our note candidates... 10:57:01 [missed] 10:57:04 DOPE: http://www.informatik.uni-bremen.de/swc/dope.html sorry 10:57:23 David: if we focus on the same use cases we will have developed a full suite of examples for those cases 10:57:26 ...eg. we could look back and say, 'we did xyz to bring foaf into mainstream fold, ... 10:57:35 ...so we should probably come up with list of these use cases 10:57:52 jjc: back to phil's earlier point... i think it is important that we don't do support of individual users 10:58:03 ...ralph talked about communities not individuals 10:58:17 ...we do latter on jena-dev list 10:58:19 phil: I agree 10:58:31 David: I see indivs supported in IG; communities supported by WG 10:58:41 burkhardt has joined #swbp 10:58:45 steve: re topicmaps angle... this skos looks like a v interesting project 10:58:58 ...collab, make sure whatever we do in the rdf/tm tf is consistent 10:59:12 al: thanks, agree; Kal Ahmed, ...[missed names] have been active w/ skos 10:59:31 ...re Published Subject Indicator, currently discussing whether to have a PSI property in SKOS 10:59:37 guus: to wrap up... 11:00:23 al: re spec document, people seem ok with that, concerns have been with the guide document 11:01:13 al: guide is at an early stage, built from our wiki content 11:01:19 ...feasible to publish for end of november 11:01:26 q+ to ask for actions 11:01:29 ack davidw 11:01:29 DavidW, you wanted to suggest standard use case scenarios across SWBP work 11:01:33 ack ralphs 11:01:33 RalphS, you wanted to address Phil's point about helping with others' pain 11:01:35 ack danbri 11:01:35 danbriscribe, you wanted to ask for actions 11:01:39 oops :) 11:01:41 q+ to ask for actions 11:01:48 guus: more discussion tommorrow? 11:02:04 al: might be useful to run new features of skos core past the WG 11:02:11 ...because of the subject indicator discussion 11:03:05 guus: so i hear two issues; 1st is potential examples, 2nd is to talk about topic maps [& denotes property] 11:03:28 ...ie. open issues within task force; alongside discussion of rel'n to topicmaps tf 11:03:37 ralph: david commented about standard use casees 11:03:59 ...guus has emphasised that there are use cases; please lets pick some. 11:04:02 q? 11:04:08 ...concern i have with foaf is that it is simple and intuitive 11:04:21 ...but foaf is already developed, and rdf friendly 11:04:31 ack RalphS 11:04:31 RalphS, you wanted to caution about standard use cases 11:04:38 guus: foaf is a description template, not a vocab 11:04:59 ralph: not clear useful to list foaf as a skos use case 11:05:40 ...anything we do, there's some community out there, who we should know about and whoese needs we should address 11:06:02 danbriscribe, you wanted to ask for actions 11:07:55 al: I could've written this by showing classic print thesauri followed by skos version; could do that, but foaf developer folks wouldn't follow. There are different communities who need different kinds of example. 11:08:02 guus: who is main community? digital library? 11:09:00 al: point is that this is skos core guide... is that the right title for the right document? 11:09:40 ...another point is a primer specifically for using skos w/ thesauri 11:09:43 "Expressing Your Thesaurus in the Semantic Web" 11:09:46 guus: how about not having skos in title 11:10:23 Steve: not just thesaurii; also controlled vocabularies, subject headings 11:10:34 (various proposals uncaptured; discussion of whether just thesauri ...) 11:11:04 all: great work alistair! 11:12:02 pepper has joined #swbp 11:12:22 rrsagent, pointer? 11:12:22 See http://www.w3.org/2004/11/01-swbp-irc#T11-12-22 11:21:35 q+ scribe volunteers welcomed [except Ralph] 11:21:40 q+ to note scribe volunteers welcomed [except Ralph] 11:31:01 RalphS, I believe the intro to http://www.w3.org/2001/sw/BestPractices/WNET/wordnet-sw-20040713.html explains how SKOS, Wordnet, and RDF/OWL fit together. Would be great if you could review that bit of the doc in particular. 11:35:28 [thanks, DanBri; I will take a look there] 11:36:50 ---wordnet TF 11:36:51 guus: history: history wordnet in rdf several times - but none endorsed by princeton 11:36:53 thanks libby 11:37:14 JeffP has joined #swbp 11:37:42 Scribe: Libby 11:37:57 ...phase one - wordnet datastructures in RDF/OWL - no changes, make it so that everytime wornet is updated, get an rdf/owl version too 11:38:24 ...brian has been working on a draft: http://www.w3.org/2001/sw/BestPractices/WNET/wordnet-sw-20040713.html 11:39:02 ...details to be worked on: wordnet has synsets, a group of terms. many linguistic relationships between the synsets and the terms 11:39:29 q+ to encourage review of wordnet-sw Intro section (re overlap between TFs, eg. wordnet vs skos vs TMs etc) 11:39:38 q- danbriscribe 11:39:45 ...main problem with the phase one conversion is lack of people's time: more work on the document and then liase with princeton 11:39:57 ...? someone was definitely interested in working on this 11:40:02 [ WordNet Task Force description is http://www.w3.org/2001/sw/BestPractices/WNET/tf ] 11:40:07 ...which maybe enough 11:40:08 s/?/Christianne Fellbaum/ 11:40:17 thanks ralph 11:40:22 [hope I spelled her name closely enough] 11:40:55 guss: issues: what shoudl the base uri be for wordnet; how shoudl updates be handled? and how shoudl words be repreesnted 11:41:41 ...this is the only document we have really. focus discussion on how to get more effort into here 11:42:07 danbri: everyone wants to do the exciting stuff not phase one stuff: this is hard wor 11:42:09 k 11:42:22 guus would love to do it if he had the time 11:43:20 danbri: good for all to review the introduction to this...easy to confuse the differnt tasks, e.g. could skos grow to address any of the wordnet tasks? 11:44:04 ....some of these are research questions e.g. similarity of structures between thesaurus and a lexical database 11:44:09 q+ re skos wordnet 11:44:26 jeremy: maybe just a few terms to connect those...maybe in a separate namespace 11:44:33 q+ to say a word on skos & wordne 11:45:05 brian: issue in modelling wordnet is : what is it you're modelling - a lexical concept, a sequence of characters? 11:45:13 [Christiane attended our 27-May WG meeting to talk about WordNet-SWBP collaboration; see http://lists.w3.org/Archives/Public/public-swbp-wg/2004May/0149.html ] 11:45:38 ....people using it in RDF want a large set of classes not "the word bicycle" 11:45:46 danrbi: yes - two traditions 11:46:05 guus: we decided to do the lexical one first and the classes one in phase 2 11:46:21 q- 11:46:44 q+ to ask guus re 'adding an interpretation later' 11:46:47 some text from guus: http://www.cs.vu.nl/~guus/public/wn.txt 11:47:23 jeremy: we could just discuss the resource issue? 11:47:47 david: do it with skos? 11:47:59 jeremy: complexifying stage 1 11:48:53 guus: problem is too many representations and people like a common reference 11:49:01 q? 11:49:54 ralph: has princeton endorsed any rdf reepresentations?
