SUSI.AI

Susi (acronym for Scientific User Support Intelligence) is an advanced AI made by people at FOSSASIA. It is an AI made by the people and for the people. Susi is an Open Source Project under LGPL Licence. SUSI.AI already has many Skills and anyone can add new skills through simple console rules. If you want to participate in the development of the SUSI server you can start by learning to deploy it on a cloud system like Google Cloud. This way whenever you make a change to Susi Server, you can test it out on various Susi Apps instantly. Google Cloud with Kubernetes provide this ability. Let’s dig deep into what is Google Cloud Platform and Kubernetes. What is Google Cloud Platform ? Google Cloud Platform lets you build and host applications and websites, store data, and analyze data on Google’s scalable infrastructure. Google Cloud Platform (at the time of writing this article) also provides free credits worth $300 for 1 year for testing out the Platform and test your applications. What is Kubernetes ? Kubernetes is an open-source system for automatic deployment, management and scaling of containerized applications. It makes it easy to roll out updates to your application with simple commands from your development machine and scale horizontally easily by adding more clusters as demand increase. Deploying Susi Server on Kubernetes Deploying Susi Server on Kubernetes is a fairly easy task. Follow up the steps to get it running. Create a Google Cloud Account Sign up for a Google Cloud Account (https://cloud.google.com/free-trial/) and get 300$ credits for initial use. Create a New Project After successful sign up, create a new project on Google Cloud Console. Let’s name it Susi-Kubernetes .  You will be provided a ProjectID. Remember it for further reference. Install Google Cloud SDK and kubectl Go to https://cloud.google.com/sdk/ and see instructions to setup Google Cloud SDK on your respective OS. After Google Cloud SDK install, run gcloud components install kubectl This will install kubectl for interacting with Kubernetes. Login and setup project Login to your Google Cloud Account using $ gcloud auth login 2. List all the projects using $ gcloud config list project [core] project = <PROJECT_ID> 3. Select your project $ gcloud config set project <PROJECT_ID> 4. Install JDK8 for susi_server setup and set it as default. 5. Clone your fork of the Susi Server Repository $ git clone https://github.com/<your_username>/susi_server.git $ cd susi_server/ 6. Build project and run Susi Server locally $ ./gradlew build $ bin/start.sh Susi server must have been started started and web interface is accessible on http://localhost:4000 Install Docker and build Docker image for Susi Install Docker. Debian and derivatives:  sudo apt install docker Arch Linux:   sudo pacman -S docker  Build Docker Image for Susi $ docker build -t gcr.io/<Project_id>/susi:v1 . Push Image to Google Container Registry private to your project. $ gcloud docker -- push gcr.io/<Project_id>/susi:v1 Create Cluster and Deploy your Susi Server there Create Cluster. You may specify different zone, number of nodes and machine type depending upon requirement. $ gcloud container clusters create <Cluster-Name> --num-nodes…

What is Susi? Susi is an open source intelligent personal assistant which has the capability to learn and respond better to queries. It is also capable of making to-do lists, setting alarms, providing weather and traffic info all in real time. Susi responds based on skills. What is a skill? How do we teach a skill? A skill is a piece of code which performs a set of actions in order to respond to the user’s query. These skills are based on pattern matching which help them mapping the user’s query to a specific skill and responding accordingly. Teaching a skill to Susi is surprisingly very easy to implement. One can take a look at the Susi Skill Development Tutorial and a video workshop by Michael Christen. I will try to give a basic idea on how to create a skill, it’s basic structure and some of the skills I developed in the first week. Prepare to create a skill: Head over to http://dream.susi.ai Create a etherpad with some relevant name Delete all text currently present in there Start writing your skill Adding to this, for testing a skill one can head over to Susi Web Chat Interface. Basic Structure for calling an API: <Regular expression to be matched here> !console:<response given to the user> { "url":"<API endpoint>", "path":"<Json path here>" } eol So, let me explain this line by line. The regular expression is the one to which the user’s query is matched first. The console is meant to output the actual response the user sees as response. In place of the “url”, the API endpoint is passed in. “path” here specifies how we traverse through the response Json or Jsonp to get the object, starts with “$.”. At last, “eol” which is the end-of-line marks the end of a skill. Let’s take an example for better understanding of this: random gif !console: $url$ {    "url" : "http://api.giphy.com/v1/gifs/trending?api_key=dc6zaTOxFJmzC",    "path" : "$.data[0].images.fixed_height" } eol   This skill responds with a link to a random gif. Steps involved: Match the string “random gif” with the user’s query. On successful match, make an API call to the API endpoint specified in “url” On response, extract the object at the specified path in the json under “path” Respond to the user with the “url” key’s value which would here be an URL of a GIF. Let’s try it out on Susi Web Chat. For this, you will first have to load your skill using the dream command followed by etherpad name: dream <etherpad name>. And then you can start testing your skill. So, we queried “random gif” and we got a response “Click Here!”. The complete URL didn’t show up because all the URLs are currently parsed and a hyperlink for each is created. So try clicking on it to find a GIF.   Now, let’s look at one more skill I developed during this period. # Returns the name of the president of a country president of *|who is the president of…
