Abstract: Navigation data generation techniques and systems are described to address the complexities of digital content and that overcome the challenges of the conventional techniques. In one example, digital content is received by a flow graph system and used to generate a flow graph that models functionality available via the digital content as graph nodes and connections between the functions as edges between the graph nodes based on a markup language of the digital content. Each of the graph nodes includes a respective utterance that describes functionality available via that node and thus is usable to locate this functionality using semantic similarity to an input query. The flow graph is used as a basis to generate navigation data.
