… Tagsets & Tagset Mappings Q1: How do we measure distributional properties in tagsets?
► POS tags encapsulate some combination of morphological & syntactic (& other?) …
When evaluating POS tagging or category induction methods involving mapping to simpler
tagset, one should report a measurement of external quality ► We propose one which
records the number of ambiguities lost in the lexicon 3. …

A problem: no standard set of categories (ie part-of-speech tags) for evaluating category induction► smaller mapped tagsets are often used (Goldwater and Griffiths 2007; Toutanova and Johnson 2008)
