Description

UD English-ESL / Treebank of Learner English (TLE) contains manual POS tag and dependency annotations for 5,124 English as a Second Language (ESL) sentences drawn from the Cambridge Learner Corpus First Certificate in English (FCE) dataset.

UD English-ESL/TLE is a collection of 5,124 English as a Second Language (ESL) sentences (97,681 words), manually annotated with POS tags and dependency trees in the Universal Dependencies formalism. Each sentence is annotated both in its original and error corrected forms. The annotations follow the standard English UD guidelines, along with a set of supplementary guidelines for ESL. The dataset represents upper-intermediate level adult English learners from 10 native language backgrounds, with over 500 sentences for each native language. The sentences were randomly drawn from the Cambridge Learner Corpus First Certificate in English (FCE) corpus. The treebank is split randomly to a training set of 4,124 sentences, development set of 500 sentences and a test set of 500 sentences. Further information is available at esltreebank.org
