Visits to International Teams
Research Stays Abroad
Raphaël Gazzotti
Date: March-April.
Visit of the Natural Language Processing research group of the Universidad Nacional de Córdoba, Argentina, for one month as a secondment of the MIREL H2020 Project.
We proceed to the tokenization of a small sample of questions and answers from the customer service of a big insurance company. Then, following a guideline, we annotated, thankfully to a graphical interface developed within the Natural Language Processing research group at the FaMAF, insurance-related concepts from this corpus and considered them as Named Entities. We mapped these concepts to two ontologies -YAGO and Property and Casualty data model developed by the Object Management Group that we translated to OWL format- [50]. We expect to map them to more ontologies and increase existing ones, like a financial ontology and another specific to communication, then ultimately to Linked Open Data. In a future step, we would like to identify and label automatically concepts using a small annotated corpus as a training set. We believe that annotated concepts can improve automatic categorization of questions and help to reason with different levels of abstraction.
