Dataset Summary

This dataset provides the data for LAMA. The dataset include a subset of Google_RE (https://code.google.com/archive/p/relation-extraction-corpus/), TRex (subset of wikidata triples), Conceptnet (https://github.com/commonsense/conceptnet5/wiki) and Squad. There are configs for each of "google_re", "trex", "conceptnet" and "squad", respectively.

The dataset includes some cleanup, and addition of a masked sentence and associated answers for the [MASK] token. The accuracy in predicting the [MASK] token shows how well the language model knows facts and common sense information. The [MASK] tokens are only for the "object" slots.

This version of the dataset includes "negated" sentences as well as the masked sentence. Also, certain of the config includes "template" and "template_negated" fields of the form "[X] some text [Y]", where [X] and [Y] are the subject and object slots respectively of certain relations.

Data Fields

The trex config has the following fields:

• uuid: the id
• obj_uri: a uri for the object slot
• obj_label: a label for the object slot
• sub_uri: a uri for the subject slot
• sub_label: a label for the subject slot
• predicate_id: the predicate/relationship
• sub_surface: the surface text for the subject
• obj_surface: The surface text for the object. This is the word that should be predicted by the [MASK] token.
• masked_sentence: The masked sentence used to probe, with the object word replaced with [MASK]
• template: A pattern of text for extracting the relationship, object and subject of the form "[X] some text [Y]", where [X] and [Y] are the subject and object slots respectively. template may be missing and replaced with an empty string.
• template_negated: Same as above, except the [Y] is not the object. template_negated may be missing and replaced with empty strings.
• label: the label for the relationship/predicate. label may be missing and replaced with an empty string.
• description': a description of the relationship/predicate. description may be missing and replaced with an empty string.
• type: a type id for the relationship/predicate. type may be missing and replaced with an empty string.

The conceptnet config has the following fields:

• uuid: the id
• sub: the subject. subj may be missing and replaced with an empty string.
• obj: the object to be predicted. obj may be missing and replaced with an empty string.

Dataset Creation

Curation Rationale

This dataset was gathered and created to probe what language models understand.

Source Data

Initial Data Collection and Normalization

See the reaserch paper and website for more detail. The dataset was created gathered from various other datasets with cleanups for probing.

Who are the source language producers?

The LAMA authors and the original authors of the various configs.

Annotations

Annotation process

Human annotations under the original datasets (conceptnet), and various machine annotations.

Who are the annotators?

Human annotations and machine annotations.

Personal and Sensitive Information

Unkown, but likely names of famous people.

Considerations for Using the Data

Social Impact of Dataset

The goal for the work is to probe the understanding of language models.

Discussion of Biases

Since the data is from human annotators, there is likely to be baises.

[More Information Needed]

Other Known Limitations

The original documentation for the datafields are limited.
