Abstract:
We discuss combining knowledge- based (or rule-based) and statistical part-of-speech taggers.
We use two mature taggers, ENGCG and Xerox Tagger, to independently tag the same text and combine
the results to produce a fully disambiguated text. In a 27000 word test sample taken from a previously
unseen corpus we achieve 98.5 % accuracy. This paper presents the data in detail.
We describe the problems we encountered in the course of combining the two taggers and discuss
the problem of evaluating taggers.
