Open source machine learning tools for developers and product teams to expand bots beyond answering simple questions.

Rasa Core's primary purpose is to help you build contextual, layered conversations with lots of back-and-forth. To have a real conversation, you need to have some memory and build on things that were said earlier. Rasa Core lets you do that in a scalable way.

RASA NLU is an open-source tool for intent classification and entity extraction. You can think of it as a set of high level APIs for building your own language parser using existing NLP and ML libraries.

Botpress is an open-source bot creation tool written in Javascript. It is powered by a rich set of open-source modules built by the community. We like to say that Botpress is like the Wordpress of Chatbots; anyone can create and reuse other people's modules.

CodeScene identifies patterns in the evolution of your code. This gives you the power to predict its future and to find the code that is hard to evolve and prone to defects. The investigation takes only minutes but saves you from future limitations, bottlenecks or maintenance issues.

CodeScene gives you a better understanding of your software systems. Here are just a few of all the questions that CodeScene will help you find answers to:

Which part of the code might become productivity bottlenecks?
Which parts of the code will be hard to maintain?
What is the technical risk when a key developer leaves the project?
Which parts of the code should we improve to get a real productivity and quality gain?
How is the knowledge distribution between teams in your codebase?

With API.AI, you can create conversational scenarios within minutes, then build advanced dialogues to manage the conversation flow with the user. Once you build your agent, you can integrate it with SDKs or use our one-click integration modules. When your product is launched, it constantly improves with machine learning and can be updated in real-time based on user interactions.

Activities and ideas for making agile retrospectives more engaging

Fractal is a tool to help you build and document web component libraries, and then integrate them into your projects.

Component (or pattern) libraries are a way of designing and building websites in a modular fashion, breaking up the UI into small, reusable chunks that can then later be assembled in a variety of ways to build anything from larger components right up to whole pages.

Fractal helps you assemble, preview and document website component libraries, and then integrate them into your web sites, apps and build processes to create joined up, ‘living’ projects.

Fractal can be run from the command line or integrated into your project via its API.

A source-control branching model, where developers collaborate on code in a single branch called ‘trunk’ *, resist any pressure to create other long-lived development branches by employing documented techniques, avoid merge hell, do not break the build, and live happily ever after.

Superset is a data exploration platform designed to be visual, intuitive and interactive.

Superset's main goal is to make it easy to slice, dice and visualize data. It empowers users to perform analytics at the speed of thought.

Superset provides:

A quick way to intuitively visualize datasets by allowing users to create and share interactive dashboards
A rich set of visualizations to analyze your data, as well as a flexible way to extend the capabilities
An extensible, high granularity security model allowing intricate rules on who can access which features, and integration with major authentication providers (database, OpenID, LDAP, OAuth & REMOTE_USER through Flask AppBuiler)
A simple semantic layer, allowing to control how data sources are displayed in the UI, by defining which fields should show up in which dropdown and which aggregation and function (metrics) are made available to the user
Deep integration with Druid allows for Superset to stay blazing fast while slicing and dicing large, realtime datasets
Fast loading dashboards with configurable caching
