The 26th of June was the first Chatbot Summit in Europe. Even better, it was held in my favorite city- Berlin.


In the opening keynote from Yoav Barel, the CEO of Chatbot Summit, he made it clear that the future of chatbots are to become personal assistants. Assistants for health, banking, travel and everything you can imagine. Peer Bentzen from Deutsche Post confirmed it in the panel discussion. Peer is a heavy user of an health assistant bot.


My highlights from the Summit (mainly focused on Development & AI and less on UX)

"As soon as it works, nobody calls it AI anymore"

a quote from 1956 by John McCarthy in the keynote by Jordi Torras from Inbenta.

AI (artificial Intelligence) is used and abused, although the definition is clear and probably different from 1956. So as soon as we will not hear about AI in chatbots anymore it means AI is working.

The hybrid approach: Unsupervised pre-learning combined system actions defined by humans

Björn Gülsdorff – Creative Virtual


This the approach we are using within ContentForces in combination with a human in the loop (see below). The Hybrid Model nr 1


A human in the loop

Chris van Pelt – Crowd Flower


A nice example with the Covfefe tweet from Donald Trump. But in the end this is the model to start and improve. Human interaction, directly used a training. The Hybrid Model nr 2


Unsupervised pre-learning for pizza toppings

Jairson Vitorino CTO from E.life

An nice example of the The Hybrid Model nr 1


Cold start the the Natuaral Language Understanding AI

With interesting panel members as Ivan Yamshchikov and Kate McCurdy.

Lack of data forces Chatbots to start rule based, to coldstart. Multilingual is even a bigger challenge. For example in Finnish every word can have many forms which increase the dimensionality (deep learning).

5 million users for an Indian dating chatbot

Haptik by Aakrit Vaish

It was all about UX, and Aakrit mentioned that they feed the bot with interesting content and the users react on it. I am wondering if the behavior of European users would be the same.


Change the habit to use the chatbot.

Meekan by Doodle (Google)

Interesting UX, between more convenient and straightforward there is a big challenge to change the behavior. In this case to move users from (Google) Calendar to Meekan.

Natural Language Processing on Steroids

And Karsten Schmidt from SAP Labs put it technically nice to together.
