Tools for Semantic Work

Is it really nearly two years since I gave the Semantic Wiki Seminar? It seems so. Not a lot seems to have been happening towards the use of semantic tools until now. I have just discovered two linked tools, VisualUnderstandingEnvironment and Zotero. I didn't discover them, I read about them in a computer magazine. Some useful things do happen.

It is also worth a note that I did some work to tidy up the pages on the Semantic Web on the C2 wiki.

CubicWeb is a tool which I have just discovered and started to work with. It provides a tool for constructing objects with semantic content using the python language, linked to a database (I am using postgreSQL). More to follow. One of the things which I want to explore is a possible link between Literate Programming and the Semantic Web - see LiterateProgrammingAndTheSemanticWeb.

Semantic Wiki Seminar 8th April 2008

I have given a seminar on Semantic Wikis in the KEG seminar series on 8th April 2008.

See http://keg.cs.aston.ac.uk/semDtls/semDtls.php?id=105 Semantic Wiki Seminar summary on KEG.

Thank you for coming and joining the discussion.

A copy of the slides is available from me for anyone who wishes. Many of the links are on this wiki anyway.

I am convinced that we need to make more use of the insights of the semantic web in the tools we use every day. I use a lot of different tools such as Outlook (for my university emails, calendar, etc.) OneNote? (quite the most interesting part of Microsoft Office 2007), Blackboard, PebblePad? (I did the training last September) and several different wikis including this one. I just wish they were better integrated and had the semantic insights of the Semantic Wiki. What can I do to help it happen? I am not sure, except ask why none of the tools work in a semantic way.

Semantic MediaWiki

Semantic MediaWiki (SMW) is an extension of MediaWiki – the wiki-system powering Wikipedia – with semantic technology, thus turning it into a semantic wiki. While articles in MediaWiki are just plain texts, SMW allows users to add structured data, comparable to the data one would usually store in a database. SMW uses the fact that such data is already contained in many articles: users just need to "mark" the corresponding places so that the system can extract the relevant data without "understanding" the rest of the text. With this information, SMW can help to search, organise, browse, evaluate, and share the wiki's content.

Ontoworld now renamed as SemanticWeb.Org

The Ontoworld wiki is now renamed and now links to Semantic Web. Up until now www.semanticweb.org was in existence as a second name. This change causes a problem for me and perhaps others, as Semantic Web is a generic term for, well, the Semantic Web and now it is also the name for a specific site, which I propose to call Semantic Web Dot Org to make it clear I am talking about the site and not the whole Semantic Web. All the remaining links on this page will need to be changed over (thanks someone) but not straight away.

There is a page about the Semantic Wiki Seminar on Semantic Web Dot Org, which is the semantic wiki I talked about in the seminar.

In the context of Semantic Web Dot Org, many wiki links can have properties attached to them which are indexed.

For example, take the page for Aston University which is there. There is a box labelled Facts about Aston University which contains information which is all gathered from the links scattered around in the text. If you click on the words Aston University you will get more information on both inbound and outbound links. You can see the links by editing the source of the page. At one point there is the following text:

Located in [[has location city::Birmingham]] in 
[[has location country::England]]

This is where two of the links are declared. The phrase has location country is a property with a page in Semantic Web Dot Org - see has location country.

New properties can be declared very easily, just by making the link. I have built one called Implementer of to describe my relationship to the OntoClean Paper example which I am implementing. There is also an inverse property Has implementer which is also declared, and the two are linked through another property Inverse. There is a network of property links which join together great deal of information.

If you have followed me this far you will see that there are references to OWL and RDF cropping up. Underlying Semantic Web Dot Org is a relationship to RDF which includes being able to export material as RDF, and links in the structure to ontologies.

Sandbox for SemanticWeb.Org

This location is a duplicate of SemanticWeb.Org which can be used for testing ideas on how semantic wikis work.


I want to discuss an ontology called OntoClean which I am using to develop examples on Semantic Web Dot Org.

A good starting point for access to OntoClean is the OntoClean Community Portal which is also a good example of Semantic Web Dot Org at work gathering data.

Please do look at those pages and either join Semantic Web Dot Org and discuss it there or discuss it on this wiki.

Ontoclean in use

The Protege ontology package has an implementation of OntoClean

There is also AEON at ontoware.org I have not evaluated these items.
