Introduction

Football, GDP and WHO

In this assignment we combined the world of football with GDP and WHO to find interesting stats and facts about them.

Frontend

Our frontend is written using HTML, CSS and JavaScript. We just need to open the index.html file in frontend directory.

Server

Our server is made using flask. To activate the server

#changing directory
$cd server

#creating a virtual environment
$python3 -m venv venv

$source venv/bin/activate

$pip3 install -r requirements.txt

#starting our server
$python3 server.py

The server runs on localhost:5000. We can leave the server running in the background.

Database

For our database, we stored the triples in the GraphDb triplestore. The directories in Data are

• Datasets: Our CSV datasets
• Mappings: Our R2RML mappings. It also contains the configs when we need to use the r2rml engine to uplift the dataset
• Outputs: The .ttl files generated from after running the r2rml engine which then would be uploaded to our triplestore

To uplift the data, just run ./update_ttl.sh in the Data directory.

NOTE: The appearances.ttl file is too large to upload using normal method. We need to create a directory ~/graphdb-import and move the appearances.ttl there. Only then it can be imported to our triplestore. See this for further information.

The GraphDb server runs on localhost:7200. The name of our repository is group_e_football.

Documentation

To see the ontology, r2rml and sparql queries documentation, please run a live server in the directory Documentation/groupE_OntologyDocumentation/ and access the index-en.html file in this directory.

Although you can access the index-en.html directly, however, if you do not run the live server, you may not be able to see the webVowl visualization of the ontology.
