MEGA UDPOS

Universal Dependencies POS tagging as part of the MEGA benchmark suite. A multilingual part-of-speech tagging dataset based on Universal Dependencies treebanks, utilizing the universal POS tag set of 17 tags across 38 diverse languages from different language families. Used for evaluating multilingual POS tagging systems.

Phi-3.5-MoE-instruct from Microsoft currently leads the MEGA UDPOS leaderboard with a score of 0.604 across 2 evaluated AI models.

Abstract

Universal Dependencies is an open community effort to create cross-linguistically consistent treebank annotation for many languages within a dependency-based lexicalist framework. The annotation consists in a linguistically motivated word segmentation; a morphological layer comprising lemmas, universal part-of-speech tags, and standardized morphological features; and a syntactic layer focusing on syntactic relations between predicates, arguments and modifiers. In this paper, we describe version 2 of the guidelines (UD v2), discuss the major changes from UD v1 to UD v2, and give an overview of the currently available treebanks for 90 languages.

MicrosoftPhi-3.5-MoE-instruct leads with 60.4%, followed by MicrosoftPhi-3.5-mini-instruct at 46.5%.
