A Survey on Phrase Mining methods for Unstructured Data
Phrase mining is a key research problem for semantic analysis and text based information retrieval. A phrase is a sequence of words that appear continuously in the text, and serves as a whole semantic unit in some particular context of documents. The aim of phrase mining involves extraction of quality phrases from large and structured sets of texts. The latest domain independent method of Seg Phrase outperforms the existing methods that rely on complex, linguistic analyzers. But still domain experts need to select quality phrases from abundant candidates. Bearing this in mind to reduce the human effort we propose the concept of automated phrase mining framework Autophrase, which supports any language without the need of POS tagger.
