Voice-driven Knowledge Graph Journey with Neo4j and Amazon Alexa

In 2016, 25% of web searches on Android were made by voice and this percentage is predicted to double by 2018.

From Amazon Alexa to Google Home, smart watches and in-car systems, touch is no longer the primary user interface.

This talk will demonstrate how graphs and machine learning are used to create an extracted and enriched graph representation of knowledge from text corpus and other data sources.

This representation is then used to map user intents made by voice to an entry point in this Neo4j-backed knowledge graph.

Every user interaction is then taken into account in any further steps and we will highlight why graphs are an ideal data structure for keeping an accurate representation of user context in order to avoid what is called “machine or bot amnesia.”

The session will conclude by explaining about how recommendations algorithms are used to predict next steps of the user’s journey.
