THATCamp CBR – Semantic web session

1 09 2010

The semantic web session was hugely popular, facilitated by Corey Wallis a software engineer who is involved in the development of additional services for the AusStage system as part of the Aus-e-Stage project.

I am particularly interested in the development of semantic web tools as an opportunity for LivingGreener to visualise data about sustainability issues. In addition to this as an artist and researcher I am starting to explore the use of semantic web and mapping tools as a way of developing creative work about family, identity. migration and place.

In short, Corey proposed a session that explored the potential use of semantic web technologies, such as the Resource Description Framework RDF, in supporting research and other projects in the humanities. Some initial questions to start the discussion include:

  • What are these types of technologies used for?
  • What kinds of activities in the humanities do they support?
  • What are the kinds of problems that we’ve used these technologies to solve?
  • What kinds of issues have been explored in using these types of technologies?
  • Sharing thoughts on success stories, war stories and other experiences with these types of technologies.

The conversation covered the following points:

  • what is the difference between semantic web and linked open data?
  • Relational data and semantic web? Relationship data operates within a schema eg. Database
  • semantic web creates definitions that can be read universally
  • semantic web google doc to share
  • ANDS funded research – Basil D – People Australia
  • local identifiers (URIs) with persistent identifiers (internal) – subjects, events, geo-locale, history
  • making sure that data is published in the right format – RDF (uni of melbourne)
  • friend of a friend – looking at relational ontologies  – People Australia links in
  • trove, skos – concept of a person, simple knowledge origin systems skos
  • link between tagging within the organisation and public interactions
  • XML represents data structure but not meaning, RDF document can be rendered to be human readable
  • you can embed RDF, RDF aarnet, RDFA, griddle into html
  • freebase?
  • seems to be a gap in developer expertise in RDF
  • sparql queries do not compress, distributed sources of data is more flexible and lighter and huge data store
  • breaking up sets of ontologies and cross referencing
  • bio ontologies, creative commons, isocat, dublin core, ontology register, schemipedia, swoogle
  • rdf browser, disco browser
  • australian pictorial resource, AMOL
  • problem with authorative data base of ontologies with folksonomies
  • understanding how ontologies are developed
  • the discussion about universal tags created by institutions vs crowdsourced, folksonomy tags has been going for over ten years – see Ontologies and Metadata

It seems that the way forward is to develop small manageable ontologies that can be woven together in a cohesive, flexible way. It is also important to create good code that follows with RDF standards. Given that there appears to be limited expertise in the area of RDF development, there is a need to build those skills to ensure the success of semantic web projects,
