2020 Talk: From Semantic Networks to Knowldge Graphs

Since the 1960s, semantic networks of various kinds have been used for knowledge representation in AI and NLP. From the mid 1990s to 2005, Tim Berners-Lee and his colleagues adapted that technology to the Semantic Web. During the past 15 years, research in AI and related fields has created new opportunities, but it has also posed challenges that were not foreseen in 2005. This talk will analyze the strengths and weaknesses of various knowledge graphs and their implications for future developments.
