Prerequisite

• Docker(Compose)

Build docker image

docker-compose build

Running specs

docker-compose run web make test

Crawl public product's info from an e-commerce

The spider script collect product info from Petlove's site. After spider script has finished, a dataset.csv file will be generated to data/external directory.

  docker-compose run web make crawl_petlove

Make a prediction

Run docker container

docker-compose up -d

Make HTTP request using curl:

curl -d '{"name": "Ração Premier Pet Formula Cães Adultos Raças Pequenas","description": "Indicada para cães adultos de raça pequena, Ração Sabor Frango, Contem apenas ingredientes nobres e selecionados sob rigoroso controle de qualidade, Pelagem bonita e saudável, rico em acido graxo essenciais, Omega 3 e Omega 6, Ajuda no equilibrio intestinal, combinação de ingredientes de alta digestibilidade, fibras alimentares e prebioticos, Enriquecido com vitaminas e minerais que proporcional maior saúde e vitalidade"}' -H "Content-Type: application/json" -X POST http://localhost:5000/api/predict

Expected response:

{
  "prediction": {
    "category": "Cachorro, Rações, Ração Seca"
  }
}

Access Jupyter notebook

docker run -it -v $PWD:/opt/nb -p 8888:8888 felixleung/auto-sklearn \
/bin/bash -c "mkdir -p /opt/nb && jupyter notebook --notebook-dir=/opt/nb --ip='0.0.0.0' --port=8888 --no-browser --allow-root"

Datasets

• A public dataset of 1980 products with 88 categories extracted from Petlove, each product has name, description and category - https://s3.amazonaws.com/product-categorization/dataset.csv
