Moko is a mythological character in the Cook Islands.

Moko may also refer to:

In the mythology of Mangaia in the Cook Islands, Moko is a wily character and grandfather of the heroic Ngaru. (Gill 1876:234).

Moko is a ruler or king of the lizards, and he orders his lizard subjects to climb into the basket of the sky demon Amai-te-rangi to spy on him. When Amai-te-rangi pulls up his basket, he is disappointed to find it full of miserable little reptiles, which escape and overrun his home in the sky (Gill 1876:234).

In computational linguistics, word-sense disambiguation (WSD) is an open problem of natural language processing, which governs the process of identifying which sense of a word (i.e. meaning) is used in a sentence, when the word has multiple meanings (polysemy). The solution to this problem impacts other computer-related writing, such as discourse, improving relevance of search engines, anaphora resolution, coherence, inference et cetera.

Research has progressed steadily to the point where WSD systems achieve sufficiently high levels of accuracy on a variety of word types and ambiguities. A rich variety of techniques have been researched, from dictionary-based methods that use the knowledge encoded in lexical resources, to supervised machine learning methods in which a classifier is trained for each distinct word on a corpus of manually sense-annotated examples, to completely unsupervised methods that cluster occurrences of words, thereby inducing word senses. Among these, supervised learning approaches have been the most successful algorithms to date.
