Dataset Card for Corpus for Knowledge-Enhanced Language Model Pre-training (KELM)

Dataset Summary

Data-To-Text Generation involves converting knowledge graph (KG) triples of the form (subject, relation, object) into a natural language sentence(s). This dataset consists of English KG data converted into paired natural language text. The generated corpus consists of ∼18M sentences spanning ∼45M triples with ∼1500 distinct relations.

Supported Tasks and Leaderboards

The intended task is data-to-text generation, taking in a knowledge graph tuple and generating a natural language representation from it. Specifically, the data is in the format the authors used to train a seq2seq language model with the tuples concatenated into a single sequence.

Languages

The dataset is in English.

Dataset Structure

Data Instances

Each instance consists of one KG triple paired with corresponding natural language.

Data Fields

• triple: Wikipedia triples of the form <subject> <relation> <object> where some subjects have multiple relations, e.g. <subject> <relation1> <object1> <relation2> <object2> <relation3> <object3>. For more details on how these relations are grouped, please refer to the paper.
• sentence: The corresponding Wikipedia sentence.

Data Splits

The dataset includes a pre-determined train, validation, and test split.

Dataset Creation

Curation Rationale

The goal of the dataset's curation and the associated modeling work discussed in the paper is to be able to generate natural text from a knowledge graph.

Discussion of Biases

From the paper:

Wikipedia has documented ideological, gender6, and racial biases in its text. While the KELM corpus may still contain some of these biases, certain types of biases may be reduced.
