Have you ever used services like Open Calais ? If yes then probably you were amazed by how easy is to automatically extract semantic information directly from the submitted text. If you are not familiar with Open Calais it is a service that extracts events, people, organisations, topics and social tags from unstructured data. I would suggest to try it. A lot of developers and companies are using such services to enrich their content, to improve discovery services, to build recommendations services and to extract analytics from content.
This is one of the main goals that the FREME project wants to achieve. To build such an open approach for extracting semantic information form open data. The FREME aims at providing a platform that will make available in a friendly way such services.
More specifically we are using the FREME e-services to enrich the metadata records for the agricultural bibliographic information that we are collecting from data providers. Just to give you a specific example: we are receiving metadata records in which the name of a specific author may have several variations e.g. Giannis Stoitsis, John Stoitsis or G.S. Stoitsis. This results in a bad user experience as the specific filter will show the three different values for the same person. It is also not possible to browse through the publications of a specific author. Using the FREME e-services we can achieve two things:
- To disambiguate the author by comparing his name against an authority file like the one maintained by ORCID and
- To enrich the metadata record by introducing also ORCID uri for the author based on which we can get more info about the specific person and thus we can show this info to the end user of our services
We do similar enrichments for organisations using the Virtual International Authority File (VIAF) and places using the Geopolitical ontology. We can also add missing terms from AGROVOC that could help in multilingual browsing and searching of the bibliographic resources.
We participated in the second plenary meeting of the FREME project that took place in Turin on Thursday 3/9 and Friday 4/9 at the very nice premises of ISMB. We discussed the progress and first results from applying FREME e-services in our workflow. Stay tuned for updates on our work.
