Morphological analysis and disambiguation are crucial stages in a variety of natural language processing applications, especially when languages with complex morphology are concerned. We present a system which disambiguates the output of a morphologi- cal analyzer for Hebrew. It consists of sev- eral simple classifiers and a module which combines them under linguistically moti- vated constraints. We investigate a number of techniques for combining the predictions of the classifiers. Our best result, 91.44% ac- curacy, reflects a 25% reduction in error rate compared with the previous state of the art.
