OpenLink Tweet Unroller — Codenamed “Outarde”, this powerful productivity tool leverages the power of RDF deployed using Linked Data principles. Outarde adds new dimensions to the creation, publication, access, and recall of Knowledge Graphs. For instance, it simplifies the transformation of Twitter Threads into Knowledge Graph nuggets for future reuse and recall using Text Search or declarative query languages such as SQL or SPARQL.
