Building the Perfect Corpus

Considerations for creating linguistically representative and diverse datasets for computational linguistics.

Why does this matter?

The quality of a corpus is largely determined by its capacity to capture the richness, diversity, and nuance of the language it represents.

A robust corpus is essential for computational linguists to avoid bias and ensure that language models actually reflect how people communicate in the real world.

5 Pillars of Corpus Design

1. Genres & Registers

To capture different styles of language, a corpus must include various text categories and situational contexts. This allows for the study of syntactic and stylistic variations.

Genre

(Hover me)

Category

Formal or thematic characteristics (e.g., Novels, News, Scientific Articles).

Register

(Hover me)

Context

Variations based on situation, formality, and relationship between speakers.

Books and Genres
Science
Arts
Economics
Everyday Life

2. Topics & Domains

Language varies drastically between specialized fields. A diverse corpus must cover a wide range of topics to capture:

  • Specialized terminologies
  • Domain-specific discourse structures
  • Unique language patterns

3. Demographic Inclusivity

To avoid bias, include texts from various demographic groups. Variations in language are often driven by:

Age Gender Socioeconomic Status Education

4. Regional & Cultural

Capture the geographical diversity of language. A globally representative corpus includes:

Dialects Idioms Cultural References

5. The Balance of Size

A corpus must be large enough for statistical significance, yet manageable enough for processing.
