Opscidia’s ontology generator
A key problem in building efficient text-mining tools is to have proper domain-specific ontologies that can be used as building blocks for other text-mining applications. These ontologies can have many usages for researchers, innovators, librarians, and others.
The value of the Ontology Generator
In the framework of OpenAIRE Open innovation call, Opscidia was selected to propose a solution to address this need. Opscidia is a French start-up created in 2019 with the mission of leveraging Open Science to increase the diffusion of research results and promote their reuse for innovation, public policy design and general public information.
The solution proposed by Opscidia is an ontology generator that consists in three layers:
- Data collection layer: here it consists mostly in harvesting the resources (API or Dumps of specific OpenAIRE communities)
- Concept detection layer: A simple, unsupervised algorithm extracts and hierarchizes concepts related to a seed concept entered by the user. It can easily scale-up both with the amount of data and with the amount of users / requests.
- Visualization layer: A visualization tool represents graphically the produced ontology and links it back to the documents of the corpus from which the ontology was created.
The results of the Ontology Generator
You can also view a video that demonstrates the Opscidia operation within OpenAIRE in the follοwing video.

User groups and the impact of the Ontology Generator to them
Such services can benefit different groups of people willing to take advantage of recent innovations:
- For research funders and policymakers to detect the future technological trends
- For researchers to improve innovative text-mining approaches
- For media and citizens, for example to fight against fake news.
For this last example, Opscidia is supported by the Vietsch Foundation to build a Science Checker, a free to access search engine that verifies scientific claims by means of analysing the pertinent and available scientific literature.
The application domain of the Ontology Generator
The exact same method could of course be applied to other OpenAIRE communities, and this is one possible continuation of this project. Similar approaches have also been used to help detect the emerging technological trends in a project with Future and Emerging Technologies group (FET) of the European commission. It can also be used to identify scientific documents useful to build a literature review. Other applications could be the inclusion into diverse downstream artificial intelligence pipelines, the enrichment of an existing ontology etc.
Sustainability of the Ontology Generator
The Ontology generator is hosted and maintained by the Opscidia team within its services production environment. Opscidia team is more than enthusiastic to extend this service beyond this project. Some possible extensions have already been drafted for other OpenAIRE communities and within the EOSC environment.
Please feel free to contact the Opscidia team if you have any suggestion.
RELATED OpenAIRE PRODUCTS/SERVICES
One of the easiest use-case of this application is to promote the exploration of a community collection from OpenAIRE connect. The application built during this project is useful to draw a map of the concepts of the collection, and to link it to the content of the collection.
As an example, the methodology developed during the project has been applied on OpenAIRE Covid19 collection and integrated into the OpenAIRE Covid 19 gateway. The result of the application of our methodology to the OpenAIRE COVID19 collection can be accessed here.
You can view the COVID-19 screencast in YouTube in the video above.
Requirements to use http://openaire.opscidia.com/ are very accessible. Users just need a browser and an internet access.
