Abstract

OntologPSMW: Debut, Tutorial and Possibilities - [ intro slides]

by: Peter P. Yim (Ontolog; CIM3)

From the beginning of ONTOLOG back in 2002, this community has been thriving in a collaborative work environment (CWE). Our CWE has included a wiki, almost from the start, which served as a shared display and a collaborative authoring workspace, and a content repository for this CoP and the related communities that its been hosting (like OOR, IAOA, Ontology Summit, to name a few.) Until now the "wiki engine" in use has been "PurpleWiki" which is a variant of usemod wiki, with Purple Numbers and other enhancements developed by Eugene Kim and ChrisDent.

Ontolog is about ready to move on, to a richer wiki platform. The "wiki engine" we will be progressing to, is "Purple SemanticMediaWiki (PSMW)". This move has been contemplated since about the time we ran the SemanticWiki mini-series here, back in the 2008/2009 time frame. The plan now, is to deploy an OntologPSMW starting in January 2013, and do parallel runs (with both wiki platforms in production) as the community gets familiar with the new wiki and collaboratively explore how to leverage the new capabilities.

Invited to present at this session are Ken Baclawski and YaronKoren. Ken co-led the psmw-dev team (with PeterYim) that has been developing the pmwx (purple mediawiki extension) as an enhancement to MediaWiki, as well as other tools and features in OntologPSMW. Yaron is among one of the most prominent and prolific developers in the SemanticMediaWiki space. Extensions developed by Yaron, like Semantic Forms and Semantic Drilldown are practically defacto standards for almost everyone working with SemanticMediaWiki's.

Yaron Koren has just recently published his new book entitled "Working with MediaWiki" - a brilliant work that fills a long overdue need to make MediaWiki's and SemanticMediaWiki's more accessible to a wider user-base. He will be giving us a tutorial at this session based on some of the most useful material he has covered in that book.

After the two presentations, we will have an extended Q&A and open discussion segment, where the community will have a chance to get answers to questions they have in mind. We will also discuss what the potentials and possibilities might be, after we have PSMW at our disposal. Among those possibilities is the use of OntologPSMW to enrich the upcoming Ontology Summit 2013 content and deliverables, or other initiatives where crowdsourcing may be a paradigm.

[09:53] Atilla Elci: ref. Baclawski slide #5 & #19 - PSMW Project (http://project.cim3.net/PSMW)

returns 404 error!

[09:54] Peter P. Yim: sorry ... the link should be http://project.cim3.net/wiki/PSMW

[09:56] Peter P. Yim: today's session page on OntologPSWM is at:

http://ontolog-02.cim3.net/wiki/ConferenceCall_2012_12_19

[09:57] Matthew West: If the purple numbers are computed, does that mean that the reference for a

particular section might change after a page has been updated (and thereby invalidate a link that

has been made to it)?

[10:01] Yaron Koren: I was wondering the same thing, actually.

[10:02] Peter P. Yim: @Matthew & Yaron - very good and important question ... let's get that answered

during the Q&A / Discussion

[10:04] Matthew West: A really good way to do it would be for there to be an underlying anchor that

did not change, and to which the link was made, but a visible representation that did

[10:02] Steve Ray: Hmm. The coding doesn't look very user-friendly.

[10:03] Peter P. Yim: @Steve - that's where YaronKoren's Semantic Forms extensions come in

[10:04] Steve Ray: OK. Unfortunately, I will have to leave around 20 minutes past the hour, so I'll

have to view the recording.

[10:07] Steve Ray: The SPARQL example did not look like normal SPARQL syntax. Not familiar with the

[] syntax.

[10:10] Peter P. Yim: == Yaron Koren presenting ...

[10:10] Amanda Vizedom: The hierarchical relationship between "Categories" in a Knowledge

Organization Structure is usually a subtopic/supertopic relationship, rather than the typically

ontological subClass/superClass relation. This causes a lot of confusion when people use KOS

hierarchies in ontological environments, or ontologies in information organization environments. One

way to resolve this is to interpret the ontological classes as eliptically named, that is, "mammals"

becomes "documents about mammals". That allows preservation of subClass relationships, but really

means that in using an ontology, one is really doing a two-layered trick, using the original

ontology and relations between things in it, but also creating & using a ontology of documents about

things in the original ontology. So far, I'm suspecting that this is such a case. Not a problem,

inherently, but something that becomes important to be clear about ! when using existing ontologies.

[10:11] Steve Ray: @Amanda: Very interesting distinction - thanks. I can see the potential for a big

mess.

[10:14] Steve Ray: These queries don't appear to be standard SPARQL. #show?

[10:44] Ken Baclawski: @Steve: #show is not SPARQL: the label on my slide was incorrect. However, we

do plan to support SPARQL.

[10:14] Steve Ray: Perhaps I'm misunderstanding. Is there a native query language, PLUS support for

SPARQL?

[10:15] Amanda Vizedom: @Steve - YW. I have done clean-up on a number of well-intended reuses of

ontologies as KOSes and vice versa, in which the different behavior of subClass and subTopic wasn't

understood. So I'm attuned to pick up that pattern. It can be done and done well, though; it's just

important to understand which layers or behaviors are using the original ontology and which are

using the corresponding KOS/document ontology.

[10:20] Steve Ray: It also appears that the ontology specification language is not a standard one,

such as Turtle, or RDF-XML. I look forward to hearing how these new syntaxes map to traditional

ones. I will have to hear the answers off-line, as I must leave now.

[10:24] Peter P. Yim: @Ken, @Yaron - kindly discuss support for SPARQL queries

[10:43] Yaron Koren: [running demo] ... please point your browsers to: http://foodfinds.referata.com

[10:45] Matthew West: Sorry, have to go. Interesting stuff.

[10:50] Peter P. Yim: @Alexandra - can we get your full name, please? (you can morph into that by

clicking the "Settings" button (top center)

[10:57] Sumit Purohit: Thanks Everyone...have to go. Thanks for participation.

[11:01] Amanda Vizedom: @Ken - it's actually *very* common to reorganize and/or add sections to a

page

[11:02] Amanda Vizedom: & it may be that the TOC is enough

[11:01] Peter P. Yim: see: http://ontolog-02.cim3.net/wiki/ConferenceCall_2012_12_19

[11:05] Atilla Elci: @Peter: Do you mean to say that a purple number once use will never get used?

[11:07] Atilla Elci: If so, a purple number then provides an immediate tiny URL . That would be

wonderful.

[11:12] Amanda Vizedom: History available at TOC section level?

[11:19] Amanda Vizedom: I asked about the extent to which ontology has been incorporated into the

Ontolog PSMW so far. Ken responded that the ICOM ontology has been, and that this concerns

collaborative work, so seemed appropriate. More discussion will be open about what we want to

support.

[11:19] Ken Baclawski: The ICOM website is

https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=icom

[11:19] Amanda Vizedom: Thanks, @Ken

[11:21] Peter P. Yim: should we have another OntolgoPSMW session for Ontology Summit 2013 champions on

what-to and how-to's ... general consensus is 'yes' ... we will try to schedule one after the new

year, but before the Jan-17 Ontology Summit 2013 launch event

[11:23] Peter P. Yim: soliciting inputs to - http://ontolog-02.cim3.net/wiki/Demos_Prototypes_Examples &

http://ontolog-02.cim3.net/wiki/Issues_Bugs_Suggestions

[11:28] Terry Longstreth: about query language standards: There may be some synergy between SMW and

the DOL activities

[11:31] Prateek Jain: Using OWL?

[11:32] Terry Longstreth: or using Common Logic

[11:33] Prateek Jain: Yes

[11:34] Prateek Jain: I believe you can.

[11:34] Amanda Vizedom: It is not straightforward in OWL, but easy-peasy in a more expressive

ontology language. :-)

[11:34] Prateek Jain: But I will confirm it, with Pascal Hitzler

[11:34] Prateek Jain: not straightforward yes :-)

[11:34] Mike Bennett: I think as soon as we look at using RDF/OWL and queries across the wiki pages,

we need to keep Amanda's earlier point front and center. That is, the OWL thing which is "Article

about a Thing" is not the same as, but has an object property relating to, the kind of OWL Thing

which is the thing itself. Else pain will ensue.

[11:35] Yaron Koren: That's very good to know, then. Any documentation would be useful - if you find

it, I would definitely appreciate it if you sent me any links - yaron [at] wikiworks.com.

[11:35] Prateek Jain: Can you give me the exact example?

[11:35] Prateek Jain: I will just send it over to Pascal and he might be able to look at it and give

the definite answer

[11:36] Yaron Koren: Prateek - something like "Every entity that is a city should have a relationship

called "Population", and another relationship called "Mayor", and nothing else."

[11:36] Prateek Jain: Okay! I will send it over. Thanks

[11:37] Yaron Koren: Thank you!

[11:37] Mike Bennett: Happy Holidays to you Peter!

[11:37] David Mason: thanks !
