twfeel - the on-demand topic sentiment provider

WIP: Twitter is currently only data source provider

Demo

twfeel can be demoed using either:

• REST Service
• Hangouts Chat

REST Service

Note, you will have to obtain the know invocator token (token) to execute this query either in browser or from command line

curl -H "Content-Type: application/json" -X GET \
		"https://twfeel.demo.knative.tech/v1/feel/knative?token=${TW_FEEL_TOKEN}" \
		| jq "."

Hangouts Chat

Assuming the @tfeel bot has already been configured, you can use it either in direct messages (DM) by typing the name of topic

knative

or invite it to any chat room and ask the bot in your message

@tfeel knative

Slack

Assuming the @kfeel app has already been added to your Slack instance, you can use it like this

/kfeel knative

Setup

For information on how to install Knative see how to on Knative site

Deploy Service

First you will need to obtain Twitter API keys and create secrets

kubectl create secret generic twfeel-secrets -n demo \
	--from-literal=ACCESS_TOKEN=${TW_FEEL_TOKEN} \
	--from-literal=REDIS_PASS=${REDIS_PASS} \
	--from-literal=T_CONSUMER_KEY=${TK_CONSUMER_KEY} \
	--from-literal=T_CONSUMER_SECRET=${TK_CONSUMER_SECRET} \
	--from-literal=T_ACCESS_TOKEN=${TK_ACCESS_TOKEN} \
	--from-literal=T_ACCESS_SECRET=${TK_ACCESS_SECRET}

Note, if you changed any of the variable above, you will need to edit the Knative service manifest in config/service.yaml

Then deploy the service

kubectl apply -f config/service.yaml

Chat Bot

In the Google API Console, enable the Hangouts Chat API by doing the following:

• In the navigation, click APIs & Services > Dashboard.
• In the Dashboard, click Enable APIs and Services.
• Search for "Hangouts Chat API" and enable the API.

Once the API is enabled, click the Configuration tab. In the Configuration pane, do the following:
