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 Li Ding & 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); Usability: visualization and user interaction (e.g., T6); 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 Aldo Gangemi & Valentina Presutti on "Pattern-based Ontology Design" - ConferenceCall_2009_02_05
- 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.

Questions and Discussion captured from the chat session
Transcript: (lightly edited for clarity only)
Guoqian Jiang: @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)
Enrico Daga: data as wiki-page/csv... can be used as alternaive store for other extensions' data, flexible, I think...
Mike Axelrod: I think there will be uses for this approach...
Mike Bennett: 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?
Kei Cheung: nice presentation, Yaron. I just installed it for my wikineuron project. will let you know how it goes ...
Peter Dolog: well, I guess quick integration of data from legacy web applications in enterprise environment could be
an application for the external page data
Yaron Koren: Guoqian - no, I haven't really considered supporting RDF - it's too complicated...
Peter Dolog: Yaron, I might be interested in more details of your extensions
Peter Dolog: we need something similar in KIWI, in one use case, so we might learn something from you
Yaron Koren: Ah, great.
Yaron Koren: Well, you can look at the source code, for one thing - it's really not that long.
Peter Dolog: ok
Yaron Koren: (Assuming you're talking about External Data.)
Peter Dolog: well, external to the wiki
Yaron Koren: Right.
Peter Dolog: but still intranet based in enterprise terminology
Marc Feickert: Phillip, can you maintain your own list of synonyms with this extension?
Guoqian Jiang: Yaron, RDF output has more explicit semantics. in some way, you may not need interpret them by yourself.
Yaron Koren: Well, if nothing else, I haven't seen a use case for supporting RDF yet.
Michael Dale: Yaron Koren: 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
Marc Feickert: good call
Michael Dale: for example the people.xml from gov track
Yaron Koren: Maybe... it would only really be necessary if the XML had two different tags or attributes of the same name.
Marc Feickert: 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.
Yaron Koren: Sure. I'm just afraid XPath support would add a lot of complexity.
Marc Feickert: for you or for the user?
Yaron Koren: Marc - definitely for the programmer, probably for the user/admin as well.
Marc Feickert: complexity for advanced users is sometimes okay, but I understand the reluctance if it adds too much effort on your end as well
Guoqian Jiang: Philipp, does autocompletion in searchbox support the query expansion e.g. synonym?
Philipp Zaltenbach: the autocomplete shows only tile of wiki pages. wiki pages are separated in regular article pages (instances),
category pages, property pages, template pages
Marc Feickert: and how can we expand the stemming dictionaries for multiple langauges?
Ravi Sharma: Philipp, How do you connect vocabularies or define related terms, are these a reasoning or inference engine sitting
behind the Tags or serach terms?
Philipp Zaltenbach: 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.
Marc Feickert: so by expanding the wordnet project, it would trickle down to expand this?
Marc Feickert: or would there be a way to import or tranform dictionaries?
Marc Feickert: actually, I need to talk to you in depth at another time. I'll email you to set something up
Guoqian Jiang: query expansion for an external vocabulary would be very useful
Marc Feickert: agreed
Marc Feickert: we intend to cover 20-30 languages
Philipp Zaltenbach: @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.
Philipp Zaltenbach: at mark, sure feel free to mail me
Ravi Sharma: Peter Dolog, How is a single (?) Triplestoreservice related or delivered or choreographed with SOA Services in
the upper architecture layer such as COntentItemService?
Philipp Zaltenbach: 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
Guoqian Jiang: how do you represent the internal vocabularies in Halo?
Guoqian Jiang: for external vocabulary, we mapped them to wiki pages
Philipp Zaltenbach: internally we use the special relations such as "also known as" or "broader term". these pre-defined
properties are actually mapped to SKOS properties.
Guoqian Jiang: I mean we may use the same mechanism for external voca as long as we observe the rule
Marc Feickert: 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?
Philipp Zaltenbach: 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
Marc Feickert: And here I think also of text in the page that may need its own synonym separate of the page title
Marc Feickert: You've hit on my professional area, Philipp
Guoqian Jiang: Is this query expansion a separate extension?
Peter Dolog: ok, give me a second to recollect the thought and read your questions
Philipp Zaltenbach: the synonyms actually relate to the source article where you put in your semantic annotations such as "also known as:blabla"
Philipp Zaltenbach: marc, i have to leave soon, but i am looking forward to hear from you via email!
Marc Feickert: I have asked Daniel Hansch for your contact info.
Philipp Zaltenbach: the query expansion is just a "feature" of the enhanced retrieval extension which i highlighted
Guoqian Jiang: Philipp, you mean enhanced retrieval extension could be separated from Halo?
Marc Feickert: aber alles ist ausgezeichnet!
Philipp Zaltenbach: yes, it will be available as a separate extension which you can plug in into an SMW (without having to use HALO extension)
Guoqian Jiang: great
Philipp Zaltenbach: ok, i have to leave guys, cu!
Marc Feickert: Tschuss!
Guoqian Jiang: thanks, Philipp
Peter Dolog: Ravi Sharma: any store has to be connected to the entitymanager, so there is always a bit of work to connect it
Peter Dolog: content item is an entity in the data model
Peter Dolog: accessible through hibernate like interface
Peter Dolog: that you can actually query it directly
Yaron Koren: Peter: are these tags editable by everyone, or are they user-specific?
Peter Dolog: Yaron, which things?
Yaron Koren: The tags you were talking about.
Peter Dolog: Whether any person can add tags? Yes
Peter Dolog: Any user can tag
Yaron Koren: No, the question is, if one person adds a tag, can another person edit/remove it.
Peter Dolog: it depends how you set the rights control
Peter Dolog: in principle yes, if you want
Peter Dolog: but you can restrict it
Yaron Koren: I see, okay.
Peter Dolog: but if you look at the screenshot, I did not have any "-" symbol for me
Peter Dolog: so it was restricted
Peter Dolog: it was simple to make recommendations because the core datamodel is basically a triple (Content Item x Tags x Users)
Peter Dolog: similarly, access control is then simple
Peter Dolog: and then you can put a type system over it through semantic web annotations
Guoqian Jiang: good talk, Mike
Mike Axelrod: thx
Guoqian Jiang: we did meet many scenarios you described in your zoo
Yaron Koren: Peter - is this (tagging) the semantic content of KIWI, or is it in addition to the semantic content?
Peter Dolog: it is a bit tricky
Peter Dolog: actually tag is a special kind of content item
Peter Dolog: i.e. kind of a resource
Peter Dolog: which link to another "media/text" based content item
Peter Dolog: and it is cartesian
Peter Dolog: i.e you can see the link bidirectionally
Peter Dolog: I do not know if it answered your question
Yaron Koren: Okay, I think I understand...
Yaron Koren: Basially, unlike SMW, KIWI doesn't store semantic data on the page - it's all separate "resources".
Peter Dolog: yes
Peter Dolog: also concepts in an ontology are currently separate content items
Peter Dolog: and you can use them as labels for tags
Yaron Koren: Hm, okay.
Peter Dolog: also user is a content item
Peter Dolog: so content item is a base entity
Peter Dolog: and then you type it
Peter Dolog: and link instances around
Yaron Koren: Okay.
Peter Dolog: actually to clarify
Peter Dolog: we distinguish between rdf/owl annotations and tags
Peter Dolog: we allow both
Peter Dolog: and we can link them
Marc Feickert: I'm out of breath...
Li Ding: thank marc
Yaron Koren: Peter: people type in RDF directly?
Peter Dolog: well, they can, if they have an editor in their configuration
Peter Dolog: but that is not what usually happen to normal user
Peter Dolog: this is why we actually introduced tagging in the KIWI project
Peter Dolog: I cannot imagine a project manager - one of the use cases we are targeting
Peter Dolog: who would write RDF
Yaron Koren: Right.
Peter Dolog: some people in the project are working on some simple editor for kind of rdf annotations
Peter Dolog: they are actually text analysis people
Peter Dolog: and are currently making some drag and drop highliting plugin
Peter Dolog: to get those derived in writing directly
Peter Dolog: but user in fact does not see that it is RDF
Peter Dolog: but we would like to have a bit more than just tags
Peter Dolog: so we (meaning the whole project) are thinking how to support that
Yaron Koren: Right, interface is important.
Peter Dolog: But tagging seems to be acceptable
Peter Dolog: simple tagging is actually not semantic
Peter Dolog: so one way to extend it is to somehow support editing of links between ontologies and tags
Marc Feickert: can Poticus work for a non-semantic wiki? We'd love to play with it now
Peter Dolog: 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
Peter Dolog: in case, you'd like to know more
Yaron Koren: Okay, thanks.
Yaron Koren: Ploticus=awesome.
JoelNatividad: Thanks Yaron
Mike Bennett: @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!
Yaron Koren: Hey, I'm glad I did.
JoelNatividad: So glad to see you here
Mike Bennett: Hi Joel - good to see you also, the Ploticus stuff looks really exciting.
Marc Feickert: I almost wet my pants
Marc Feickert: very cool
Yaron Koren: I'm looking forward to the time-series stuff - animated graphs? Damn.
Yaron Koren: Jennifer: that's too bad. That's the first I've heard of people not being able to find pages after they create them.
Yaron Koren: (Although maybe people just don't tell me about it.)
Yaron Koren: ...created using forms, that is.
Ravi Sharma: 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
Jennifer Vendetti: 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.
Yaron Koren: Oh, okay, that makes sense.
Jennifer Vendetti: ... even though we have documented this.
Yaron Koren: Jennifer: I think, having seen your forms to some extent, that there might be ways to make them a little more usable.
Yaron Koren: Like, for instance, having a dropdown for the plugin name using the "values from category" parameter.
Jennifer Vendetti: 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.
Yaron Koren: 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.
Yaron Koren: These are both relatively new features.
Jennifer Vendetti: 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!!
Yaron Koren: Sure.
Ravi Sharma: to speakers: is there a uniform tagging and query standard emerging other than GRRDLE such as agreed Meta-tags etc?
Mike Axelrod: bye all!
