The intuition that different text classi\ufb01ers behave in qualitatively different ways has long motivated attempts to build a better metaclassi\ufb01er via some combination of classi\ufb01ers. We introduce a probabilistic method for combining classi\ufb01ers that considers the context sensitive reliabilities of contributing classi\ufb01ers. The method harnesses reliability indicators\u2014variables that provide a valuable signal about the performance of classi\ufb01ers in different situations. We provide background, present procedures for building metaclassi\ufb01ers that take into consideration both reliability indicators and classi\ufb01er outputs, and review a set of comparative studies undertaken to evaluate the methodology.<\/p>\n","protected":false},"excerpt":{"rendered":"
