[SMW-devel] Results of the first day of SMWCon
Hi everyone! You can now watch all the talks that were on the first day of SMWCon. http://www.youtube.com/playlist?list=PLwtfwT1GnUQRaLki-YcF-_n8ndayi--W5 Here is a small summary for those who haven't been at the event. The day have begun with magnificent talk about Wikidata from its project leader, Denny Vrandečić. In some sense Wikidata implements the original vision of SMW and make the Wikipedia semantically annotated. We next had three sessions. First one was pretty technical and was dedicated mostly to performance issues: after the traditional talk about the current state of the project by Markus and Jeroen, Nischay told about the new storage meschnism in SMW. Then Eloy describes how SMW is used in Wikia and what benefits it gives to the wiki-owners and what problems it sometimes caused. Second session was not about SMW but about the other wiki engines that have similar functions. OntoWiki that separates the text and the semantic annotations is used by AKSW laboratory for a lot of Linked Data projects. BlueSpice, an extension bundle to make MediaWiki more user-friendly and ready-to-use in the enterprises. KWARC tools that allows to include machine-readable data to the mathematical content. There are a lot of things SMW community can learn from these great tools. Third session was dedicated to SMW applications in different domains. We've seen how SMW helps people to support structured discussion about the ontology objects (Cicero system). The other talk was about using enhanced SMW for synchronizing the long-term strategies of organizations to design the common future (Foresight creation). Benedikt shows how to apply the platform for financial analysis of a small organization. Finally Remco presented the case of government application of SMW (Architectural Knowledge). Ask questions here and on the talk's pages! Cheers, - Yury Katkov, WikiVote -- Monitor your physical, virtual and cloud infrastructure from a single web console.

[SMW-devel] s13n stands for semantification
Hi everyone! I talked about the topic of semanticfication of the MediaWiki extension with a lot of people in SMWCon and saw the great interest to this topic. We have tried to describe the problem on this page: http://semantic-mediawiki.org/wiki/User:Yury_Katkov/s13n_stands_for_semantification To the users: if you're interested in topics of s13n and have the use case that is not described there - please describe it. To the developers: let's think together what's needed to be done in the SMW core to make s13n of the extensions cleaner and easier. Also the rough time/effort estimate would be great (maybe SMW companies can sponsor the development?)

Re: [SMW-devel] s13n stands for semantification
Hi Markus! That's very nice! How hard/long is that task? We can now use something like SMWStore::updateDataBefore hook, but not good approach sometimes: with voting and history s13n you'll need to create a lot of property values each time the data is updated. When you semantify the page history you'll need to create several hundreds datavalues representing the revisions of the current page - that's too exprensive. - Yury Katkov, WikiVote On Fri, Nov 16, 2012 at 4:34 PM, Markus Krötzsch mar...@semantic-mediawiki.org wrote: On 16/11/12 11:27, Yury Katkov wrote: Hi everyone!

Re: [SMW-devel] s13n stands for semantification
s13n of page history is just converting all revision data into properties and subobjects. Many promising usecases have been show in Semantic History extension: http://tw.rpi.edu/proj/semhis.wiki/index.php/Main_Page Here are some examples of questions that can be answered with s13n of history: - Show me the edits made by postdocs - Show me the edits that were commented as 'style improvement' - Who has changed the first name of James Hendler? - What kind of properties do users from Category:Developers change mostly? - Yury Katkov, WikiVote On Fri, Nov 16, 2012 at 7:24 PM, Nischay Nahata nischay...@gmail.com wrote: Hi Yury, On Fri, Nov 16, 2012 at 8:02 PM, Yury Katkov katkov.ju...@gmail.com wrote: Hi Markus!

Re: [SMW-devel] [Semediawiki-user] s13n stands for semantification
Hey, Can you clarify the idea of named graphs a little bit? And what storage overhead we have in them? Instead of having rows such as ( subject id, property id, value ) in the store, you instead have ( subject id, property id, value, graph id ) Of course our schema is more complex then this, but it's the same idea.
