Dataset Card for "MobIE"

Dataset Summary

This script is for loading the MobIE dataset from https://github.com/dfki-nlp/mobie .

MobIE is a German-language dataset which is human-annotated with 20 coarse- and fine-grained entity types and entity linking information for geographically linkable entities. The dataset consists of 3,232 social media texts and traffic reports with 91K tokens, and contains 20.5K annotated entities, 13.1K of which are linked to a knowledge base. A subset of the dataset is human-annotated with seven mobility-related, n-ary relation types, while the remaining documents are annotated using a weakly-supervised labeling approach implemented with the Snorkel framework. The dataset combines annotations for NER, EL and RE, and thus can be used for joint and multi-task learning of these fundamental information extraction tasks.

This version of the dataset loader provides NER tags only. NER tags use the BIO tagging scheme.

Data Fields

The data fields are the same among all splits.

• id : a string feature.
• tokens : a list of string features.
• ner_tags : a list of classification labels, with possible values including O (0), B-date (1), I-date (2), B-disaster-type (3), I-disaster-type (4), ...
