Abstract

This paper presents WarMemoirSampo, a portal that provides semantic search and navigation of video interviews with Finnish World War II veterans. The portal associates video fragments with contextual data extracted from the video transcriptions, enabling users to find suitable video segments via faceted search and highlighting relevant content in the video being watched. This is carried out by processing natural language texts in order to extract named entities, keywords and lemmas. The result is a Linked Data Knowledge Graph that underpins the portal. We describe the collaboration between Natural Language Processing and Semantic Web technologies used in order to produce these results.
