OpenData meets the Semantic Web at WOD2013

With a few people from Logilab we went to the 2nd International Workshop on Open Data (WOD), on the 3rd of june.

Although the main focus was an academic take on OpenData, a lot of talks were related to the Semantic Web technologies and especially LinkedData.

The full program (and papers) is on the following website. Here is a quick review of the things we though worth sharing.

  • privacy oriented ontologies :
  • interesting automations done to suggest alignments when initial data is uploaded to an opendata website
  • some opendata platforms have built-in APIs to get files, one example is Socrata :
  • some work is being done to scale processing of linked data in the cloud (did you know you could access ready available datasets in the Amazon cloud ? DBPedia for example )
  • the data stored in wikipedia can be a good source of vocabulary on certain machine learning tasks (and in the future, wikidata project)
  • there is an RDF extension to Google Refine (or OpenRefine), but we haven't managed to get it working out of the box,
  • WebSmatch uses morphological operators (erosion / dilation) to identify grids and zones in Excel Spreadsheets and then aligns column data on known reference values (e.g. country lists).

We naturally enjoyed the presentation made by Romain Wenz about with the unavoidable mention of Victor Hugo (and CubicWeb).

Thanks to the organizers of the conference and to the National French Library for hosting the event.
