LitBank is an annotated dataset of 100 works of English-language fiction to support tasks in natural language processing and the computational humanities, described in more detail in the following publications:
-
David Bamman, Sejal Popat and Sheng Shen (2019), "An Annotated Dataset of Literary Entities," NAACL 2019.
-
Matthew Sims, Jong Ho Park and David Bamman (2019), "Literary Event Detection," ACL 2019.
-
David Bamman, Olivia Lewke and Anya Mansoor (2020), "An Annotated Dataset of Coreference in English Literature", LREC.
LitBank currently contains annotations for entities, events, entity coreference, and quotation attribution in a sample of ~2,000 words from each of those texts, totaling 210,532 tokens.

The entity annotation layer of LitBank covers six of the ACE 2005 categories in text:
- People (PER): Tom Sawyer, her daughter
- Facilities (FAC): the house, the kitchen
- Geo-political entities (GPE): London, the village
- Locations (LOC): the forest, the river
- Vehicles (VEH): the ship, the car
- Organizations (ORG): the army, the Church
The targets of annotation here include both named entities (e.g., Tom Sawyer) and common entities (the boy). These entities can be nested, as in the following:

The event layer in LitBank identifies events with asserted realis (depicted as actually taking place, with specific participants at a specific time) -- as opposed to events with other epistemic modalities (hypotheticals, future events, extradiegetic summaries by the narrator).
| Text | Events | Source |
|---|---|---|
| My father’s eyes had closed upon the light of this world six months, when mine opened on it. | {closed, opened} | Dickens, David Copperfield |
| Call me Ishmael. | {} | Melville, Moby Dick |
| His sister was a tall, strong girl, and she walked rapidly and resolutely, as if she knew exactly where she was going and what she was going to do next. | {walked} | Cather, O Pioneers |
For more, see: Matt Sims, Jong Ho Park and David Bamman, "Literary Event Detection," ACL 2019.
The coreference layer in LitBank covers the six ACE entity categories outlined above (people, facilities, locations, geo-political entities, organizations and vehicles); while the entity tagging above only covers proper noun phrases (Tom Sawyer) and common noun phrases (the boy), the coref annotations also cover personal pronouns (he) as well.
We annotate three different categories of coreference phenomena -- coreference of identity (which links a mention in text to a discourse entity); copula (which links an attribute mention to another mention); and apposition (which links an appositive expression to another mention).
| Phenomenon | Example | Source |
|---|---|---|
| Coreference | One may as well begin with [Helen]x's letters to [[her]x sister]y | Forster, Howard's End |
| Copula |  |
Melville, Bartleby, the Scrivener |
| Apposition |  |
Conrad, Heart of Darkness |
Annotations largely follow OntoNotes guidelines (though singleton mentions are annotated here), with several departures for literary style (including the distinction between generic/specific mentions, near-identity and the revelation of identity). For more on the coreference criteria used in these annotations, see David Bamman, Olivia Lewke and Anya Mansoor (2020), "An Annotated Dataset of Coreference in English Literature", LREC.
The quotation layer in LitBank identifies all instances of direct speech in the text, attributed to its speaker.
| Quote | Speaker | Source |
|---|---|---|
| — Come up , Kinch ! Come up , you fearful jesuit ! | Buck_Mulligan-0 | Joyce, Ulysses |
| ‘ Oh dear ! Oh dear ! I shall be late ! ’ | The_White_Rabbit-4 | Carroll, Alice in Wonderland |
| “ Do n't put your feet up there , Huckleberry ; ” | Miss_Watson-26 | Twain, Huckleberry Finn |
This layer captures dialogue in quotation marks and other typographical markers (such as dashes in Joyce's Ulysses), and excludes strings wrapped in quotation marks that do not constitute dialogue, such as the use of scare quotes for emphatic use (for jargon, neologisms or irony), titles of works of art, and the mention of a term (as distinct from its use).
Speaker labels are identical to those in the coref/ section of LitBank, to enable linking the quotation and coreference layers.
For more on the quotation annotations, see this paper.
A trained tagger (which can be used to tag entities and events in new text) can be found in the tagger/ directory. (A model for coreference resolution is coming shortly.)
The corpus is drawn from the public domain texts on Project Gutenberg, and includes individual works of fiction (both novels and short stories) that include a mix of high literary style (e.g., Edith Wharton's Age of Innocence, James Joyce's Ulysses) and popular pulp fiction (e.g., H. Rider Haggard's King Solomon's Mines, Horatio Alger's Ragged Dick). We select approximately 2,000 words from each of 100 texts; the total annotated dataset contains 210,532 tokens.
