1 ..........Earliest algorithms for automatically assigning part-of-speech Stochastica Inflection RULE BASED.CO None.d 2 ..is the study of the way words are built up from smaller meaning-bearing units Morphemes a Inflection bo Derivation.co None.d 3 A real HMM tagger isn't just choosing the best tag for a simple word but the best sequence of tags for an entire sentence 4 All the nodes at each level are expanded once before going to the next (lower) level Depth-Firsta Prefixes.b Breadth-First Expansion None.de 5 In Semantic analysis we take linguistic inputs and constructing meaning representations 6 In agenda parsing Search states consist of partial trees and a pointer to the next input word in the sentence 7 In bottom up parsing we guarantee that any parse in progress will be S-rooted 8 Inference refer generically to a system's ability to draw valid conclusions based on the meaning representation of inputs and its store of background knowledge Inputs that mean the same thing should have the same meaning representation
