OpenData meets the Semantic Web at WOD2013
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 : http://l2tap.org/
- 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 : http://dev.socrata.com/
- 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).
Thanks to the organizers of the conference and to the National French Library for hosting the event.
