... would expect the performance of a generic WSD system to drop when moving to the domain corpus for domain- related words (cf. Table 1), while the performance would be similar for generic words. In ... deploying WSD systems in specific domains. We will also show that, given the source corpus, our technique can save up to 60% of effort when tagging domain- related occur- rences. We per...
