Knowledge extraction and footprint generation using the GeoSpace Body of Knowledge

Abstract. Knowledge footprints are visualisations of personal and organisational expertise. They can be used for capturing, sharing and matching expertise in the context of promotion, research exposure, project collaboration, etc. We have developed a method for creating footprints in the geospatial domain, based on resources created by persons and organisations and using the GeoSpace Body of Knowledge as a shared, standardised vocabulary. We deployed an NLP-based keyword extraction method to annotate resources with GeoSpace BoK concepts and constructed a knowledge graph to connect these BoK concepts to personal or organisational profiles. Footprints are then created by querying the knowledge graph and visualizing the results. Initial tests have been carried out to validate the generated footprints.
