Content Tagging in Yle Areena: improving quality and process

Semantic tagging of video and audio content makes content 'smarter', which makes it possible to provide cost-efficiently personalised user experiences in an OTT service such as Yle Areena. In theory, every tag should describe the content. However, due to the long tail and wide variety of content a broadcaster such as Yle publishes, and due to the distribution nature of how content and tagging is created, maintaining consistent and correct tagging is sometimes challenging. This presentation discusses measures to improve our tagging process, presents our findings and current work in this area, and outlines future possibilities.
