... converted to dependency trees us- ing Stanford Parser (Marneffe et al., 2006). 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...

... differences hold to a lesser degree when a partial dictionary is provided. With MLHMM, different tokens of the same word type are usually assigned to the same cluster, but types are assigned to clusters ... We would also like to thank Noah Smith for providing us with his data sets. Eisner, 2005). Nearly all of these approaches have one aspect in common: the goal of learning is to id...

... state of a simple finite-state automaton that only has two states. The 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 ... is to enable the quality and nature of discussions that occur within an on-line discussion board to be communicated in a summary to a potential new- comer or group moderators.

... a tool for predicting metabolic engineering strategies to optimize plant freezing toler- ance. We confirm that a significant improvement in freezing tolerance in plants involves multiple regulatory ... respect to the dynamics of freezing tolerance revealed a significant correlation of sucrose synthesis and degradation with the process of cold acclimation. We conclude that acclimation to lo...

It should be pointed out that binding of the inducer to TetR does not lead to ... molecules of [Mg–Tc] + to TetR leads to changes in the tertiary structure of the protein, one can expect that these changes may lead to a decrease in the tendency of the protein to agg...

Our objective is to discover from document clusters, the latent topics that are organized into hi- erarchies following (Haghighi ... by organizing topics into a tree of a fixed depth L (Fig.1.a). Each candidate sentence o m is assigned to a path c o m in the tree and each word w i in a given sentence is assigned to a hi...

... document into a text-like document of acoustic tokens. Thus a spoken document can be represented by a count vector of acoustic tokens and token n-grams in the vector space. We apply latent semantic ... document into a sequence of tokens. As illustrated in Figure 2, a token can be of different sizes, ranging from a speech feature frame, to a phoneme, to a lexical word. A token is...

The prototype translates spoken ... Translator (Rayner et al., 2000a)). At run-time, the system behaves essentially like a phrasal translator which allows some variation in the input language. This is close in spirit to the appro...
