CLT seminar: Barbara Plank - Using hyperlinks to improve taggers for Twitter

SEMINAR

Tweets are notoriously hard to analyze, because of spelling variations and the limited context available, but tweets are about real-world events, often described in more details on websites they link to. If the websites are easier to analyze, we may project our analysis of unknown or ambiguous words from the websites to the tweets. We show how such projections can be used to improve POS and NER tagging of tweets, achieving error reductions up to 18.4% on various datasets.
