## Architecture
![architecture](https://raw.githubusercontent.com/sameer-goel/Smart-HR-Bot-with-SentimentAnalysis-Integrated-with-SMS-and-other-services/master/images/readme/hrbot.png)

## Motivation to build this bot
Bot is built for those employees (say warehouse field workers) who does not have internet access and line up to a paper based register,  to log basic daily tasks. With this bot they can do it using SMS, Call, Ask Alexa as regular dialog coversation like you are asking your assitant or friend to do the task for you.

The task this bot can do are:

1. Logging daily work hours.
2. Calculate total pay for the month.
3. FAQ search like polcies, agent, salary etc
4. Most importantly, all the interactions are beging analyzed by Amazon Comprehend for sentiment analysis. This way if the user is not happy we can divert the interation immidiatly to human.
You can always add more more HR functionalities like vacations calander, leave balance etc
