Past – Present – Future with Semantic A.I.

How can we utilize the power of technology to enable us to preserve historical data and connect vast amounts of content, people, and intent while helping us understand trends that might predict the future?

Strategic use of Well-Implemented Thesauri, Semantic Footprinting, and Concept-Based Tagging

This panel discussion is presented jointly with Lizzy Jongma, Joop Vanderheiden and Ioanna Lytra and takes a deep dive into the fascinating world of historical and archaeological documentation and explores the information sources and research methodologies available to those who are seeking to gain a richer understanding of Semantic A.I. and connect knowledge sources in a meaningful way.

Our panelist, Lizzy Jongma will discuss how setting up a comprehensive World War II thesaurus provided by PoolParty benefited her organization by giving meaning, matching objects and establishing a holistic framework for knowledge and information about the Second World War.

Next, Joop Vanderheiden presents a case study in which a solution for adding metadata to archaeological reports minimizes manual tagging effort, yet offers a rich search and discovery experience.

Finally, Ioanna Lytra will focus on PoolParty Text Mining and Natural Language Processing (NLP) capabilities, in particular, will explain the technologies behind automatic concept extraction and disambiguation, semantic classification, and context-based recommendations.

This panel discussion showcases the role that well-implemented thesauri, Semantic Footprinting and concept-based tagging including common and current challenges historians and knowledge engineers are facing along with various use case discussions.
