Résumé
We introduce an end-to-end methodology (from text
processing to querying a knowledge graph) for the sake of
knowledge extraction from text corpora with a focus on a list of
vocabularies of interest. We propose a pipeline that incorporates
Natural Language Processing (NLP), Formal Concept Analysis
(FCA), and Ontology Engineering techniques to build an ontology
from textual data. We then extract the knowledge about
controlled vocabularies by querying that knowledge graph, i.e.,
the engineered ontology. We demonstrate the significance of the
proposed methodology by using it for knowledge extraction from
a text corpus that consists of 800 news articles and reports about
companies and products in the IT and pharmaceutical domain,
where the focus is on a given list of 250 controlled vocabularies.
