Hierarchical Semantic Classification: Word Sense Disambiguation with World Knowledge

Massimiliano Ciaramita, Thomas Hofmann, Mark Johnson
2003 International Joint Conference on Artificial Intelligence  
We present a learning architecture for lexical semantic classification problems that supplements task-specific training data with background data encoding general "world knowledge". The model compiles knowledge contained in a dictionaryontology into additional training data, and integrates task-specific and background data through a novel hierarchical learning architecture. Experiments on a word sense disambiguation task provide empirical evidence that this "hierarchical classifier" outperforms a state-of-the-art standard "flat" one.
