GUM is an open source corpus of richly annotated English texts from 16 genres: academic, bio, courtroom, conversation, essay, fiction, interview, letters, news, podcasts, speeches, textbooks, travel, vlogs, how-to and Reddit forum discussions. The corpus is created by students as part of the Computational Linguistics curriculum at Georgetown University and is available under Creative Commons licenses.

This is the first version of GUM series 10, containing roughly 228K tokens annotated for:

 �

- Multiple POS tags (100% manual gold PTB, extended PTB, converted CLAWS5 and UPOS) and UD morphological features

- Manually corrected lemmatization and morphological segmentation

- Sentence segmentation and rough speech act (manual)

- Document structure using TEI tags (paragraphs, headings, figures, captions etc., all manual)

- Constituent and dependency syntax (manually corrected Universal Dependencies, and PTB parses from gold tags with function labels and enhanced dependencies)

- Information status (given-active/inactive, accessible-inferable/common ground/aggregate, and new)

- Entity type, salience and coreference annotation (including non-named entities, singletons, appositions, cataphora and several types of bridging), as well as Centering Theory annotations

- Entity linking (Wikification) of all named entities with Wikipedia articles, including their non-named and pronominal mentions

- Discourse parses in enhanced Rhetorical Structure Theory (eRST) and discourse dependencies

- Discourse signal annotations classified into 9 major and 45 minor types indicating how the presence of a relation is marked (based on the Signaling Corpus scheme)

- Abstractive summaries for each document (two summaries per document in the test set)
