... and tagging. In preprocessing, (A) we separate the text into paragraphs (i.e., sequences of tokens), (B) we determine tokens in the paragraphs, and (C) we assign possible tags to each token. ... separated into different tokens if they are joined together. Natural spaces and line breaks are also regarded as tokens. (C). We assign tags to each token based on the type of the token....

We con- vert the tokens in training data to lower case, and re-tokenize the sentences using the same tokenizer from ... sensitive to parser er- rors; on the other hand, integrated model is forced to use a longer distortion limit which leads to more search errors during decoding time. It is possible to 9...

... automaton is set to initial state (q 0 ) at the top of a message. It makes a transition to state (q 1 ) when it encounters a quoted span of text. Once in state (q 1 ), the automa- ton remains in ... a span of text is to the spans of text in the parent message. This is computed using the mini- mum of all cosine distance measures between the vector representation of the span of...
