Overview

CREES automatically annotates short texts. It identifies if a text is about a crisis, crisis-types and information-types.
The Crisis Event Extraction Service (CREES) provides multiple functions for annotating short text documents for helping to classify large amount of short document (e.g. tweets) by 1) identifying if a document is related to a crisis event (e.g., fire, earthquake); 2) the type of event discussed and, 3) the type of information present in a document.

The CREES add-on provides three different customs functions that can be applied on textual columns or individual cells for annotating the contained text. Each cell should contain a small document similar in length to tweets.

The CREES add-on makes available the following functions:

- CREES_RELATED: Identifies if a short text document discusses a crisis event (returns one of the following labels: non-related, related).

- CREES_EVENT: Identifies the type of event discussed within a short textual document (returns one of the following labels: bombings, collapse, crash, derailment, earthquake, explosion, fire, floods, haze, meteorite, none, shootings, typhoon, wildfire).

- CREES_INFO: Identifies the type of information discussed within a short textual crisis-related document (returns one of the following labels: affected_individuals, caution_and_advice, donations_and_volunteering, infrastructure_and_utilities, not_applicable, not_labeled, other_useful_information, sympathy_and_support).
More information about each function can be obtained in the built-in documentation. You can access it by typing its the function name in a spreadsheet cell.
