New ladderpath index measures language complexity using pattern reuse

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new metric called the ladderpath index to measure language complexity. This index quantifies the steps required to reconstruct a sequence by reusing recurring substructures, drawing from algorithmic information theory. When applied to 21 parallel corpora, the ladderpath index showed remarkable consistency across languages, suggesting a universal complexity level. The findings also indicate a trade-off between different linguistic levels, such as character inventory and vocabulary, supporting the idea that total complexity is conserved. AI
