WikiMorph: Learning to Decompose Words into Morphological Structures

WikiMorph is a JSON dataset that contains word breakdowns for English words. These word breakdowns primarily consist of morphological compounds (both from English and the word's etymology) along with each compound's associated definition. It also contains other fields that might be useful, such as syllables and parts-of-speech tags. The dataset contains entries for 355,782 unique words and 505,033 total entries. The data collection process for this dataset was described in the paper "WikiMorph: Learning to Decompose Words into Morphological Structures", with some additional updates after publication.
