SemanticWiki mini-series Background
The Semantic Wiki mini-series a 6-month mini-series comprising Talks, Panel Discussions and Online Discourse. The series is co-organized by FZI Karlsruhe, Mayo Clinic, Ontolog, RPI Tetherless World Constellation and Salzburg Research, Austria. This represents a collaborative effort between members from academia, research, software engineering, semantic web and ontology communities. The 6-month mini-series intends to bring together developers, administrators and users of semantic wikis, and provide a platform where they can conveniently share ideas and insights. Through a series of (mainly virtual) talks, panel discussions, online discourse and even face-to-face meetings, participants will survey the state-of-the-art in semantic wiki technology and get exposure to exemplary use cases and applications. Together, they will study trends, challenges and the outlook for semantic wikis, and explore opportunities for collaboration in the very promising technology, approach or philosophy which people has labeled "semantic wiki."

This series of virtual events will dovetail into the face-to-face workshop: "Social Semantic Web: Where Web 2.0 Meets Web 3.0" at the AAAI Spring Symposium (March 23-25, 2009 at Stanford, California, USA - see: http://tw.rpi.edu/sss09 ).

See: our SemanticWiki mini-series homepage and the developing program for the rest of the series.

Session Abstract: Semantic Wiki Applications & Use Cases (2): horizontal applications
Session Abstract: by LiDing & JieBao - [ slides ]

We will be focusing general purposed applications and use cases that can be applied across many domains. Our presenters at this session will take us through applications such as: Data oriented computing: privacy, protection, distributed data, inference (e.g., T1, T2); Supporting community and collaboration (e.g., T3, T4, T5, L1)þ; Usability: visualization and user interaction (e.g., T6);þ and Methodology: design pattern and quality control (e.g. L2).


 * T1: YaronKoren - External Data in Semantic MediaWiki - [ slides ]
 * Abstract: A demonstration of how external data can be imported painlessly into an SMW wiki using the External Data extension.


 * T2: PhilippZaltenbach - Expansion of MediaWiki search: The enhanced retrieval extension - [ slides ]
 * Abstract: The search mechanism of MW was often considered a weak spot of the MW engine. Meanwhile popular installations such as Wikipedia include a more sophisticated search engine - called MWSearch - based on Lucene. We will introduce our enhanced retrieval extension that is built on top of MWsearch. The major plus of this extension is the increase of recall by incorporating related terms and concepts, such as synonyms, broader and narrower terms.


 * T3: PeterDolog - Tag Based Recommendations in KIWI - [ slides ]
 * Abstract: In this talk I will talk about how we utilized the flexible SOA architecture and widgets to extend the KIWI semantic wiki with tag based recommendations.


 * T4: MikeAxelrod - Sheparding the zoo, a lighthearted chat about fostering collaboration and wiki culture in a large corporate environment. - [ slides ]
 * Abstract: This brief presentation will touch on a few of the challenges faced in developing a semantic wiki in a large organization. The focus will be on introducing semantic wiki concepts to people representing a wide range of concerns and technical abilities, and how we might bring them together in semantic wiki-space.


 * T5: MarcFeickert - A Semantic Wiki for Your Grandmother - [ slides ]
 * Abstract: FamilySearch has produced a wiki to help the public a) learn how to perform genealogical research to find their ancestors and b) collaborate with genealogy experts of different areas to aid in research. We have decided to shift our wiki to a semantic architecture in order to take advantage of the rich tagging that will allow better browsing and searching of the wiki from multiple integrated tools at http://www.familysearch.org. The challenge is to make such a wiki usable by our main focus group, which consists primarily of retired senior citizens with little to no knowledge of how to use a computer application. The SMW+ package offers the WYSIWYG features and integration of wiki tools that will allow us to accomplish our goal. In this presentation, I will talk more about the purpose of the wiki, our target audience and their needs, the design of our ontology, our use of Semantic Forms and other tools for easing the editing process. I will additionally talk about some specific challenges that we face, namely: incompatibility of SMW+ and current MediaWiki versions, how to convert existing pages to an SMW format, and how best to allow wiki contributors to effectively contribute to the ontology.


 * T6: JoelNatividad - Visualizing Semantic Inline Query Results with SRF-Ploticus - [ slides ]
 * Abstract: Apart from SRF-GooglePie and SRF-GoogleBar, which themselves had data security limitations - there was no generic charting/plotting package to visualize Semantic Inline Query Results in Semantic MediaWiki. This talk is a quick overview and introduction of the new result printer which seeks to fill this gap - SRF-Ploticus.  Leveraging Ploticus' flexibility, we will show how SRF-Ploticus can visualize inline query results - from simple pie and bar charts, to more specialized "semantic-friendly" formats like frequency distributions, scatter plots and heatmaps.

Lightning Talks:

 * L1: JenniferVendetti - The Stanford Protege Wiki -  [ slide ]
 * Abstract: the presenter will be talking about the SemanticMediaWiki implementation used by the Protege team (at the Stanford Center for Biomedical Informatics Research) to support the Protege community, which includes over 100,000 registered users.


 * L2: EnricoDaga - ODP & Evaluation Wikiflow - [ slides ]
 * Abstract: this will be a brief presentation on our ODP wiki portal for ontology design patterns, and on "Evaluation WikiFlow," an extension to support workflow for evaluation and certification of articles in a SemanticMediaWiki environment.
 * see also the presentation by AldoGangemi & ValentinaPresutti on "Pattern-based Ontology Design" - ConferenceCall_2009_02_05

Questions and Discussion captured from the chat session:
Transcript: (lightly edited for clarity only)

GuoqianJiang: @Yaron, for the input format, do you consider the RDF output from SMW itself as one of inputs for your extension?

Michael Dale: and it gets really useful when you use it in templates : )

EricRLindahl: This seems like a way for a single-step rewrite. What about rewrites in general? Using other ground terms within the page vs. URI resolution rewrite algorithms.

EricRLindahl: (also per Jiang's SPARQL type question)

EnricoDaga: data as wiki-page/csv... can be used as alternaive store for other extensions' data, flexible, I think...

MikeAxelrod: I think there will be uses for this approach...

MikeBennett: What about Genericode - this is a way of maintaining selection lists of things like ISO country codes. Is that something that is supported by these mechanisms?

KeiCheung: nice presentation, Yaron. I just installed it for my wikineuron project. will let you know how it goes ...

PeterDolog: well, I guess quick integration of data from legacy web applications in enterprise environment could be an application for the external page data

YaronKoren: Guoqian - no, I haven't really considered supporting RDF - it's too complicated...

PeterDolog: Yaron, I might be interested in more details of your extensions

PeterDolog: we need something similar in KIWI, in one use case, so we might learn something from you

YaronKoren: Ah, great.

YaronKoren: Well, you can look at the source code, for one thing - it's really not that long.

PeterDolog: ok

YaronKoren: (Assuming you're talking about External Data.)

PeterDolog: well, external to the wiki

YaronKoren: Right.

PeterDolog: but still intranet based in enterprise terminology

MarcFeickert: Phillip, can you maintain your own list of synonyms with this extension?

GuoqianJiang: Yaron, RDF output has more explicit semantics. in some way, you may not need interpret them by yourself.

YaronKoren: Well, if nothing else, I haven't seen a use case for supporting RDF yet.

Michael Dale: YaronKoren: probably would be good to support Xpath via some xml lib integration

Michael Dale: in case you need fine grain access to xml attributes and what not

MarcFeickert: good call

Michael Dale: for example the people.xml from gov track

YaronKoren: Maybe... it would only really be necessary if the XML had two different tags or attributes of the same name.

MarcFeickert: if you are not in charge of writing the XML, it could

Michael Dale: it could also be a shorter expression / less logic to get at a given piece of data.

YaronKoren: Sure. I'm just afraid XPath support would add a lot of complexity.

MarcFeickert: for you or for the user?

YaronKoren: Marc - definitely for the programmer, probably for the user/admin as well.

MarcFeickert: complexity for advanced users is sometimes okay, but I understand the reluctance if it adds too much effort on your end as well

GuoqianJiang: Philipp, does autocompletion in searchbox support the query expansion e.g. synonym?

PhilippZaltenbach: the autocomplete shows only tile of wiki pages. wiki pages are separated in regular article pages (instances), category pages, property pages, template pages

MarcFeickert: and how can we expand the stemming dictionaries for multiple langauges?

RaviSharma: Philipp, How do you connect vocabularies or define related terms, are these a reasoning or inference engine sitting behind the Tags or serach terms?

PhilippZaltenbach: no we are not using external vocabularies at the moment for the query expansion. the only external vocabulary (for getting synonyms) is wordnet. but that is done by the MWsearch extension.

MarcFeickert: so by expanding the wordnet project, it would trickle down to expand this?

MarcFeickert: or would there be a way to import or tranform dictionaries?

MarcFeickert: actually, I need to talk to you in depth at another time. I'll email you to set something up

GuoqianJiang: query expansion for an external vocabulary would be very useful

MarcFeickert: agreed

MarcFeickert: we intend to cover 20-30 languages

PhilippZaltenbach: @marc: you can of course use different languages for annotating synoyms in your wiki. at the moment we simply do not care what a users specifies in the wiki as synonym. so you are free to use different languages.

PhilippZaltenbach: at mark, sure feel free to mail me

RaviSharma: PeterDolog, How is a single (?) Triplestoreservice related or delivered or choreographed with SOA Services in the upper architecture layer such as COntentItemService?

PhilippZaltenbach: the connecting of external vocabularies (even in different languages) is an issue we have on our radar, but as i said, we have not investigated further on how to realize that

GuoqianJiang: how do you represent the internal vocabularies in Halo?

GuoqianJiang: for external vocabulary, we mapped them to wiki pages

PhilippZaltenbach: internally we use the special relations such as "also known as" or "broader term". these pre-defined properties are actually mapped to SKOS properties.

GuoqianJiang: I mean we may use the same mechanism for external voca as long as we observe the rule

MarcFeickert: is it possible to use those properties to define synonyms for a single page? Like asking the contributor to input them into a semantic form?

PhilippZaltenbach: we didn't want to force the not-technical user to use properties such as "skos:altLabel" or "skosrefLabel". but when you export your ontology these skos properties will be serialized too

MarcFeickert: And here I think also of text in the page that may need its own synonym separate of the page title

MarcFeickert: You've hit on my professional area, Philipp

GuoqianJiang: Is this query expansion a separate extension?

PeterDolog: ok, give me a second to recollect the thought and read your questions

PhilippZaltenbach: the synonyms actually relate to the source article where you put in your semantic annotations such as "also known as:blabla"

PhilippZaltenbach: marc, i have to leave soon, but i am looking forward to hear from you via email!

MarcFeickert: I have asked Daniel Hansch for your contact info.

PhilippZaltenbach: the query expansion is just a "feature" of the enhanced retrieval extension which i highlighted

GuoqianJiang: Philipp, you mean enhanced retrieval extension could be separated from Halo?

MarcFeickert: aber alles ist ausgezeichnet!

PhilippZaltenbach: yes, it will be available as a separate extension which you can plug in into an SMW (without having to use HALO extension)

GuoqianJiang: great

PhilippZaltenbach: ok, i have to leave guys, cu!

MarcFeickert: Tschuss!

GuoqianJiang: thanks, Philipp

PeterDolog: RaviSharma: any store has to be connected to the entitymanager, so there is always a bit of work to connect it

PhilippZaltenbach:

PeterDolog: content item is an entity in the data model

PeterDolog: accessible through hibernate like interface

PeterDolog: that you can actually query it directly

YaronKoren: Peter: are these tags editable by everyone, or are they user-specific?

PeterDolog: Yaron, which things?

YaronKoren: The tags you were talking about.

PeterDolog: Whether any person can add tags? Yes

PeterDolog: Any user can tag

YaronKoren: No, the question is, if one person adds a tag, can another person edit/remove it.

PeterDolog: it depends how you set the rights control

PeterDolog: in principle yes, if you want

PeterDolog: but you can restrict it

YaronKoren: I see, okay.

PeterDolog: but if you look at the screenshot, I did not have any "-" symbol for me

PeterDolog: so it was restricted

PeterDolog: it was simple to make recommendations because the core datamodel is basically a triple (Content Item x Tags x Users)

PeterDolog: similarly, access control is then simple

PeterDolog: and then you can put a type system over it through semantic web annotations

GuoqianJiang: good talk, Mike

MikeAxelrod: thx

GuoqianJiang: we did meet many scenarios you described in your zoo

YaronKoren: Peter - is this (tagging) the semantic content of KIWI, or is it in addition to the semantic content?

PeterDolog: it is a bit tricky

PeterDolog: actually tag is a special kind of content item

PeterDolog: i.e. kind of a resource

PeterDolog: which link to another "media/text" based content item

PeterDolog: and it is cartesian

PeterDolog: i.e you can see the link bidirectionally

PeterDolog: I do not know if it answered your question

YaronKoren: Okay, I think I understand...

YaronKoren: Basially, unlike SMW, KIWI doesn't store semantic data on the page - it's all separate "resources".

PeterDolog: yes

PeterDolog: also concepts in an ontology are currently separate content items

PeterDolog: and you can use them as labels for tags

YaronKoren: Hm, okay.

PeterDolog: also user is a content item

PeterDolog: so content item is a base entity

PeterDolog: and then you type it

PeterDolog: and link instances around

YaronKoren: Okay.

PeterDolog: actually to clarify

PeterDolog: we distinguish between rdf/owl annotations and tags

PeterDolog: we allow both

PeterDolog: and we can link them

MarcFeickert: I'm out of breath...

LiDing: thank marc

YaronKoren: Peter: people type in RDF directly?

PeterDolog: well, they can, if they have an editor in their configuration

PeterDolog: but that is not what usually happen to normal user

PeterDolog: this is why we actually introduced tagging in the KIWI project

PeterDolog: I cannot imagine a project manager - one of the use cases we are targeting

PeterDolog: who would write RDF

YaronKoren: Right.

PeterDolog: some people in the project are working on some simple editor for kind of rdf annotations

PeterDolog: they are actually text analysis people

PeterDolog: and are currently making some drag and drop highliting plugin

PeterDolog: to get those derived in writing directly

PeterDolog: but user in fact does not see that it is RDF

PeterDolog: but we would like to have a bit more than just tags

PeterDolog: so we (meaning the whole project) are thinking how to support that

YaronKoren: Right, interface is important.

PeterDolog: But tagging seems to be acceptable

PeterDolog: simple tagging is actually not semantic

PeterDolog: so one way to extend it is to somehow support editing of links between ontologies and tags

MarcFeickert: can Poticus work for a non-semantic wiki? We'd love to play with it now

PeterDolog: Yaron, both architecture and some details on the whole KIWI data model is described here: http://www.kiwi-project.eu/images/stories/deliverables/d3.1_kiwi_architecture_final.pdf

PeterDolog: in case, you'd like to know more

YaronKoren: Okay, thanks.

YaronKoren: Ploticus=awesome.

JoelNatividad: Thanks Yaron

MikeBennett: @Joel: thanks for your kind mention of the EDM Council Semantics Repository

JoelNatividad: It would not have been possible without all the help and feedback

JoelNatividad: you gave during the dev process

JoelNatividad: Hi Mike!

YaronKoren: Hey, I'm glad I did.

JoelNatividad: So glad to see you here

MikeBennett: Hi Joel - good to see you also, the Ploticus stuff looks really exciting.

MarcFeickert: I almost wet my pants

MarcFeickert: very cool

YaronKoren: I'm looking forward to the time-series stuff - animated graphs? Damn.

YaronKoren: Jennifer: that's too bad. That's the first I've heard of people not being able to find pages after they create them.

YaronKoren: (Although maybe people just don't tell me about it.)

YaronKoren: ...created using forms, that is.

RaviSharma: Joel: Excellent semantic plugin through Queries, it does have general value such as in BI OLAP Reports, my own opinion, you can probably offer to Excel or other databses this as a add-on similar to what financial analysts use as excel @risk, but very useful and is this likelty to be open source?

JoelNatividad: @Ravi: it is open source and the good thing about CSV is that it opens in Excel without a problem

JoelNatividad: @Ravi: perhaps, we can create Excel Bundles too in addition to the PDF Bundle

JenniferVendetti: Yaron: sorry - I was perhaps speaking too fast during my 3 minute talk. What I meant to say is that sometimes users enter something slightly incorrect in a form and then their plug-in is listed under an area that they didn't anticipate. The fix would be to correct the category or property that they entered, but they don't always seem to know what they have done wrong because they are unaware of the strict ontological structure in place for the plug-ins library.

YaronKoren: Oh, okay, that makes sense.

JenniferVendetti: ... even though we have documented this.

YaronKoren: Jennifer: I think, having seen your forms to some extent, that there might be ways to make them a little more usable.

YaronKoren: Like, for instance, having a dropdown for the plugin name using the "values from category" parameter.

JenniferVendetti: Yaron: Great - I am very happy for your suggestions. I will look at this values from category parameter. Sounds like it would be great for solving data entry problems.

YaronKoren: You can also have the title of the new page be automatically-generated, if the name is meant to just fit a format based on the page's data.

YaronKoren: These are both relatively new features.

JenniferVendetti: Oh - I didn't know about the auto-generation of new page names. Sounds like we should use this as well. Thank you for this suggestion!!

YaronKoren: Sure.

RaviSharma: to speakers: is there a uniform tagging and query standard emerging other than GRRDLE such as agreed Meta-tags etc?

MikeAxelrod: bye all!

Duane Searsmith: thanks!

MarcFeickert: thanks for all the fish

EnricoDaga: thank you all
