Starting in early 2016, cloud vendors started to promote the concept of bots as a cool new feature and new way for users to interact with their applications within the enterprise. Understanding the general acceptance of a bot as a user interface, the push to gain traction in the space began in earnest. Seeing this shift in emphasis in the vendor landscape prompted PSC Labs to create an investigation team for a short-term project.
In this presentation, Adam Lepley (@AdamLepley) presented the first of a number of talks (here, here and here) he has given on the MS Bot Framework, how it works, why it was created and how easy it is to use.
What is the Microsoft Bot Framework?
Chat bots are not a new concept. Various web sites and chat clients have been leveraging varied forms bots for many years, but mostly with the emphasis on consumer facing applications. Targeting chat applications also comes with the benefit of building on a platform the user already is familiar with. It also removes the friction of leaning a new application and lessens the burden on developers on creating complex custom UI.
Within the lab we always like to learn about a new technology and then make a plan to better understand it and demonstrate capability in it. The plan was initially to download the examples, install, learn and then expand on what we learn and make our own examples with broader applicability to PSC clients.
We looked into:
What did we find?
Adam discussed and demonstrated how easy it is to create a bot using the framework. He was able to build a hello world bot in about 10 minutes and publish it to a point where we could actually interact with it in the meeting itself.
The investigation team created the three bots aimed at demonstrating increased productivity gains and enhanced user experiences:
The common assumption is text is the primary integrations when using chat clients. This is mostly true when two humans communicate over chat, but as it relates to bots, we have a variety options Microsoft provides with its abstraction.
The bot framework supports text (plain and rich), images (up to 20 Mb), video (up to 1 mins), buttons and the following rich content cards…
In addition to the rich content cards, Microsoft has released a separate service which enables you to build more complex card content layouts which can be rendered from data coming from the bot framework. This also exposed more native platform specific custom rendering of cards.
We set out to build a bot which would help fill out weekly timesheet for our consultants. Our bot has two main features: displaying and creating a weekly timesheet. For displaying the previous week’s timesheet, used a carousel card which can display a collocation of cards representing the days of the week. Each card also has a set of buttons which can either link to additional actions within the bot, or external links to an existing website.
Product information Bot
We created a bot demonstrating the ability to search a product database which in turn triggered an external API call to an associated Azure machine learning service. Users can interact with the bot via a series of question and answers. e.g. “What product are you searching for? Please select one of the following”. The results are then fed back to the bots in the form of a chart graphic. This bot demonstrates a powerful way to access a variety of on demand reports right within a chat client.
Productivity Bot using Natural Language interpretation
We used the Azure LUIS service (Language Understanding Intelligent Service), which is a part of Microsoft’s cognitive services and uses machine learning to help derive intent from text. Users can use an unstructured text request to “create a task” or “create new task” or “I want a new task” which the LUIS service derives the intent to be “Create a Task”. Using the secure integration with and external task tracking service (Trello) the bot is then able to ask the user the necessary questions to create a task based on user inputs.
Bots are being used today by startups and some commercial enterprises trying to break into the corporate enterprise space. Our time spent with the Microsoft Bot Framework has convinced us that bots are ready for the enterprise and there are use cases for their effective implementation today.
