Recommendation System for EOSCF

The recommendation system component focuses on creating recommendations for a requested resource. So far, its data source is only the mongo of the RS.

Use cases that are being implemented: https://wiki.eoscfuture.eu/display/EOSCF/RS+Content-based+Use+Cases

V2 BREAKING

1. All the API urls have an added v1 eg. http://0.0.0.0:4559/similar_services/recommendation -> http://0.0.0.0:4559/v1/similar_services/recommendation
2. The recommendation responses have changed to match RecommendationSet

{
  "panel_id": "similar_services",
  "recommendations": [
    12, 23, ...
  ],
  "explanations": [
    "explanation1", "explanation2" ...
  ],
  "explanations_short": [
    "explanation_short1", "explanation_short2" ...
  ],
  "score": [
    0.7, 0.6, ...
  ],
  "engine_version": "v1"
}

Building and Running

Prerequisites:

1. Read access to RS Mongo (from Cyfronet)
2. Read/write access to our Internal Mongo (from Athena)
3. Read/write access to our internal Redis storage

Build and run:

1. Make sure that you have added the .env file in the project root
2. Run docker build -t rs-image . -f Dockerfile-rs
3. Run docker run -p <port>:4559 rs-image

The image can be deployed using docker-compose if the .env variables are set correctly.
