Using machine learning to monitor and optimize chatbots

[A version of this post appears on the O’Reilly Radar.]

The O’Reilly Data Show Podcast: Ofer Ronen on the current state of chatbots.

In this episode of the Data Show, I spoke with Ofer Ronen, GM of Chatbase, a startup housed within Google’s Area 120. With tools for building chatbots becoming accessible, conversational interfaces are becoming more prevalent. As Ronen highlights in our conversation, chatbots are already enabling companies to automate many routine tasks (mainly in customer interaction). We are still in the early days of chatbots, but if current trends persist, we’ll see bots deployed more widely and take on more complex tasks and interactions. Gartner recently predicted that by 2021, companies will spend more on bots and chatbots than mobile app development.

Like any other software application, as bots get deployed in real-world applications, companies will need tools to monitor their performance. For a single, simple chatbot, one can imagine developers manually monitoring log files for errors and problems. Things get harder as you scale to more bots and as the bots get increasingly more complex. As in the case of other machine learning applications, when companies start deploying many more chatbots, automated tools for monitoring and diagnostics become essential.

The good news is relevant tools are beginning to emerge. In this episode, Ronen describes a tool he helped build: Chatbase is a chatbot analytics and optimization service that leverages machine learning research and technologies developed at Google. In essence, Chatbase lets companies focus on building and deploying the best possible chatbots.

Here are some highlights from our conversation:

Democratization of tools for bot developers

It’s been hard to get the natural language processing to work well and to recognize all the different ways people might say the same thing. There’s been an explosion of tools that leverage machine learning and natural language processing (NLP) engines to make sense of all that’s being asked of bots. But with increased capacity and capability to process data, there’s now better third-party tools for any company to take advantage of and build a decent bot out of the box.

… I see three levels of bot builders out there. There’s the non-technical kind where marketing or sales might create a prototype using a user interface—like maybe Chatfuel, which requires no programming, and create a basic experience. Or they might even create some sort of decision tree bot that is not flexible, but is good for maybe basic lead-gen experiences. But they often can’t handle type-ins. It’s often button-based. So, that’s one level, the non-technical folks.
