Jesse Wang presented on the Microsoft Office Connector, which leverages Microsoft Office applications to bring semantic information to users from various sources. The connector allows users to navigate and interact with semantic data graphs within Office applications. It also includes an API for inputting and modifying semantic data. Wang demonstrated configuring semantic data sources like MediaWiki and databases, and using the connector to edit and access semantic information from within Office tools with no special formatting required. The goal is to provide relevant contextual information to Office users from linked semantic sources.
