Personal Chatbot Resume

Personal Facebook Messenger Chatbot created using wit.ai Artificial Intelligence software, Heroku Node.Js server, and Facebook's developer console. Chatbot can be accessed through my personal website at http://johancornelissen.com.

Intention

This chatbot was designed to autonomously assist recruiters viewing my personal resume website. It serves to answer basic questions about my experience, hobbies, personal projects, autonomously without my involvement. By using wit.ai open-source artificial intelligence software the javascript code can detect the user's intentions with confidence.

Tools Used

• Facebook Developer Console : https://developers.facebook.com/apps
• Heroku : https://www.heroku.com
• Wit.Ai : https://wit.ai

Future Enhancements:

For the future, it is recommended that the index.js code is tidied up. This can be done by creating JSON files for each of the intents as well as for each "type" entity such as the "job_type" entity. This would allow the code to be seperate from the data used to power the bot and removes unnecessary code clutter.

Additionally, the chatbot can always be improved using more AI training and extra intents and keywords.
