Abstract
Illustrated embodiments provide a computer implemented method, an apparatus, and a computer program product for unsupervised stemming schema learning and lexicon acquisition from corpora. In one illustrative embodiment, the computer implemented method obtains a corpus from corpora, analyzes the corpus to deduce a set of possible stemming schema and reviews and revises the set of possible stemming schema, to create a pruned set of stemming schema. The computer implemented method further deduces a lexicon from the corpus using the pruned set of stemming schema.
