# Uncommon Types

Free text data that is not necessarily common across verticals. Examples: company/business name, product descriptions, reviews, notes, etc.

Telmai can offer: 

Frequency analyzer to identify placeholder or over-represented data 

Statistical analysis of built-in features (length, spaces, tokens etc) 

Language detection (separate data from different geographies) \[for distant future] 

Tokenization and NLP analysis of frequent or important words 

ML score (our DQ score)
