متن کاملDoes Size Really Matter?
Investigators have pondered whether or not ESP size has an impact on mercury capture by sorbent injection or deposition on fly ash. If important, ESP size would then have an impact on how effectively a power plant captures mercury and can comply with mercury control requirements. There are two possible elements to the impact of ESP size. First, does a larger ESP enable more mercury capture to o...
متن کاملDoes negation really matter?
We explore the role negation and speculation identification plays in the multi-label document-level classification of medical reports for diseases. We identify the polarity of assertions made on noun phrases which reference diseases in the medical reports. We experiment with two machine learning classifiers: one based upon Lucene and the other based upon BoosTexter. We find the performance of t...
