I have a corpus consisting of sentences that are to be categorised in order to train a text categorisation algorithm.
I am looking for a (preferably web-based) tool that:
- Allows me to input a list of sentences;
- Define a set of categories, for example: economics, sports, science, life;
- Has a user interface to present to a coder/annotator one sentence after the other, allowing him/her to classify the sentence into zero, one, or more of the previously defined categories;
- Provides some way to export the sentences together with their categories.
Ideally, the tool would allow some of the sentences to be categorised by several coders (to measure coder reliability/agreement) and feature a REST-based API for data export.
