Different datasets were used for this benchmark:

• Generic: is a set of tweets with comments about celebrities, brands, movies and products. The tweets were collected with Twitter API and tagged by humans using CrowdFlower platform.

The rest of the datasets are part of the Crowdflower's data for everyone initiative:

• Products & brands: tweets with comments about multiple brands and products. The full dataset can be accessed here.

• Apple products: tweets with comments about Apple products. The full dataset can be accessed here.

• Airlines: tweets with comments about different US airlines. The full dataset can be accessed here.

Scripts provided:

• api_benchmarks.py runs all the APIs classifications, just set the following variables in the main script:

  • api_name = to the name of the API to run (monkeylearn, metamind, alchemyAPI
  • dataset_name = the name of the dataset to run ["generic", "products", "apple", "airlines"]

• get_accuracies.py calculates the accuracy, precision and recall of each category (positive, neutral and negative). You must select the dataset to run the calculations at the top of the script.

• settings.py before running the scripts, you must fill this file with your tokens for each API.
