... We deliberately avoid reasoning about utterances as co- ordinated rational behavior, as earlier systems did; this allows us to get by with a much simpler logic. The problem we solve encompasses the genera- tion ... this state; all other atoms are as- sumed to be false. Actions have a number of param- eters, as well as a precondition and effect, both of which are logical formulas. Wh...

... (V H )with protein A was used as a surrogate for direct stability measurements. The V H domains in camelid heavy chain antibodies are most similar to the classical V H 3 family and as such bind protein ... the wild type host, whereas clear sequence preferences were observed in destabilized hosts. As the stringency of the screen increased, the functional solutions increasingly resembled...

... detection, we used a multiclass classifier that labels each token independently. 3 Since over 92% of the anchor phrases in our evaluation domain contain a single word, we simplify the task by re- ducing ... anchor phrases in the training corpus to their syntactic head word (e.g., “acts” for the anchor “acts as a costimulatory signal”). We implemented this model using a logistic re- gression...

... parsing methods have been used. Partial parsing was usually fast enough, but it also generated noisy data_" as many as 50% of all generated phrases could be incorrect (Lewis and Croft, 1990). ... In our system the database text is first pro- cessed with a fast syntactic parser. Subsequently cer- tain types of phrases are extracted from the parse trees and used as compound...
