Overview

• A bot is a remote controlled software program that can interact with a human, do some automated tasks like searching in Bing, ordering pizza for you or giving recommendation based on your choices, just like a real human being. • Bots are software programs while ro-bots are mechanical as

well as software programs.• Examples, Siri, Cortana, SmarterChild of AOL messenger etc.

What is a Bot ?

How Traditional bots are built?

• Hell lot of language parsers to identify grammar and meaning of utterances.• Fixed response based on logic.• Strong dependence on database and AI. • Regular expressions to identify keywords.• Not easy, Complex code, Lots of research work.• Identify Domain knowledge and personality development just like

humans. • Separate set of API needed to provide integration to other services. • Expensive and needs to be marketed separately.

How traditional Bots are built?

Why Bot Framework?

• Easy to use and easy to learn.• Comprehensive documentation.• Years of experience on language understanding is provided

for free as service (LUIS). • Support for multiple languages and standards (REST, .NET,

NodeJS)• Supports built in integration with Microsoft Research AI

Service (LUIS) for natural language understanding. • Connector services to host BOTs over pre-existing channels

Other 3rd party APIs.

• Bots are based on HTTP standards• Direct line APIs are used by each connector to communicate with

Bots.• Standard Authorization headers can be used for

BotAuthentication or even you can opt for custom authentication.• Conversation is based on pooling of HTTP Get.• Each conversation creates an ID to identify state.

Insights

• Conversations are gradually becoming an integral part of digital life• It is hard for a service to have humans to respond to every

questions• Conversational User Interface developed by Microsoft and used in

Cortana is an example how a personal digital assistant can help you in daily life.• Easy to develop with new APIs. • Integration to common set of services.• A need of modern world.

Dialogs and Forms

• Dialogs provides state full conversation• Dialog is a class implemented from IDialog maintains a stack of

conversation context. • Conversation state is stored as a State Service and is portable

across different machines. • Form flows provide guided conversation allowing the users to

choose path based on their own choices. • Wizard based approach implemented on top of Dialog Model.
