How to build Facebook Chatbots with IBM Watson

Niklas Heidloff    

I’ve open sourced a simple sample of a chatbot for Facebook that leverages IBM Watson Dialog and IBM Watson Natural Language Classifier for conversations with users.

Get the code from GitHub.

The GitHub project contains a sample of a Facebook bot built on the Facebook Messenger Platform which is currently available as beta. The sample bot is pretty simple but might people give some ideas how to use cognitive Watson services and how to host the bot on Bluemix.

The sample bot shows recent tweets with a positive or negative sentiment about a specific topic via the Insights for Twitter service. Check out the screenshots folder for more information.

The left screenshot shows the usage of the Dialog service. The right column shows additionally the Natural Language Classifier. In this example users can type in ‘awesome’ which is a word that is not hardcoded anywhere.

facebookbot5

I’ve implemented the bot via Node.js. In order to invoke the action that reads the tweets I’ve extended the dialog definition with the JavaScript code which is supposed to be invoked.

<item>Alright. Here are the {Sentiment} tweets about {Topic}:$ExecCode$showTweets(sender, "{Topic}", "{Sentiment}")</item>

In order to use buttons in the chat I’ve extended the dialog definition with the button data.

Rather than clicking on buttons users can also type in text like ‘awesome’. Rather than hardcoding all alternatives the Watson classifier is used to determine whether users are interested in positive or negative tweet. The id of the classifier is defined as part of the dialog definition.

<item>Are you interested in positive or negative tweets?$ShowButtons$[{"type":"postback","title":"Positive","payload":"positive"},{"type":"postback","title":"Negative","payload":"negative"}]#3a84cfx63-nlc-5285</item>

Deploying TensorFlow Models to Kubernetes on IBM Cloud
Mon, Dec 11th 2017 1:45p   Niklas Heidloff
Ansgar Schmidt and I open sourced a sample that shows how to use TensorFlow to recognize certain types of flowers. The first version of the sample used the MobileNet model which we deployed to the serverless platform OpenWhisk to run the predictions. This article describes how to deploy a TensorFlow model to Kubernetes. TensorFlow supports various image recognition models that can be retrained for certain objects. MobileNet is small and can be run in OpenWhisk. The more precise and bigger Incept

Tutorials how to build Solutions on the IBM Cloud
Mon, Dec 11th 2017 8:21a   Niklas Heidloff
In addition to Patterns and How-Tos there is another good resource for developers to learn how to use the IBM Cloud. The Solution Tutorials provide step-by-step instructions on how to implement common patterns based on best practices and proven technologies. I like these tutorials for several reasons: They cover typical scenarios many developers need to understand when getting started with the IBM Cloud. They are well written and easy to follow. Every tutorial is one page with all the content y

Sample Application how to use TensorFlow in OpenWhisk

TensorFlow provides predefined models that can be retrained to recognize certain objects in images. OpenWhisk is a serverless platform that executes functions in the cloud. With Kubernetes you can run heavy workloads in the cloud, for example the training of new TensorFlow models. Check out our open source sample that shows how to use these technologies together to recognize certain types of flowers. Get the code from GitHub or try out the live demo. Let me summarize how Ansgar Schmidt and I hav

Deploying the TensorFlow Inception Model on the IBM Cloud
Tue, Nov 28th 2017 11:22a   Niklas Heidloff
As a developer I’m trying to better understand how developers work together with data scientists to build applications that leverage machine learning. In this context one key question is how developers can access models from their applications. Below is a quick introduction to TensorFlow Serving and a description how to deploy TensorFlow models onto the IBM Cloud. Here is the description of TensorFlow Serving from the home page: “TensorFlow Serving is a flexible, high-performance ser

Visual Recognition with TensorFlow and OpenWhisk
Mon, Nov 27th 2017 2:01p   Niklas Heidloff
My colleague Ansgar Schmidt and I have built a new demo which uses TensorFlow to predict types of flowers. The model is trained in a Kubernetes cluster on the IBM Cloud. Via a web application pictures can be uploaded to initiate the prediction code which is executed as OpenWhisk function. We’d like to open source and document this demo soon. Keep an eye on our blogs. For now here is a screenshot of the web application. As starting point for this demo we’ve used a codelab from Google

Watson Conversation How-Tos have been published
Tue, Nov 21st 2017 8:22a   Niklas Heidloff
I’ve written two How-Tos which describe how to use the Watson Conversation tools Ansgar Schmidt and I had open sourced. The new page on developer.ibm.com contains How-Tos which describe everything that might be of interest for developers using the IBM Cloud. In contrast to patterns How-Tos are typically shorter and sometimes contain ‘only’ documentation and no source code.

Building Facebook Messenger Bots with Botkit and Watson
Thu, Nov 16th 2017 10:54a   Niklas Heidloff
I’ve implemented a sample Facebook Messenger bot which leverages the Node.js library Botkit and IBM Watson Conversation. With Botkit you can build bots for Slack, Facebook Messenger, Twilio and other messaging clients. For natural language understanding different services can be used, for example IBM Watson, Api.ai, Wit.ai or Rasa. Most of the code can be shared for Slack and Facebook Messenger bots. Check out the code on GitHub. Similarly to my sample Slack bot, the Facebook Messenger bo

Creating Alexa Skills with OpenWhisk and IBM Watson
Thu, Nov 16th 2017 8:43a   Niklas Heidloff
My first code pattern (formerly known as developer journeys) has been published on developer.ibm.com/code. The pattern describes how to build Alexa skills with OpenWhisk. Rather than using intent and entity identification from Alexa, Watson Conversation is used. This allows developers to define conversation flows declaratively and developers can reuse conversations that are available in the Bot Asset Exchange. My colleague Mark Sturdevant improved the documentation and created a video. Check out

Integrating Applications without writing Code
Tue, Nov 14th 2017 2:52p   Niklas Heidloff
IBM App Connect is an IPaaS (Integration Platform as a Service) to connect different applications without having to write code. Similarly to IFTTT users are typically business users or citizen developers from line of business departments. App Connect provides currently roughly 50 connectors to integrate applications like Salesforce, SAP, Slack and Gmail. See the documentation for details. Users can graphically build flows that are either event-triggered, for example if a document is changed in a

This week I attended W-JAX in Munich, Germany, which is a developer conference with 1400 attendees with a focus on Java and enterprise technologies. My colleagues and I presented and demonstrated the IBM Cloud and the IBM Code developer site. Below are some pictures. The IBM team: Discussions with developers at the booth: I gave a session about Slack bots and IBM Watson Conversation: One thing I really liked was a demo another company gave at their booth. They connected Anki Overdrive cars to
