... HTH functions could be performed by both isoforms, although for antenna development only full-length HTH was sufficient. It may therefore be that Meis2e- like proteins are functional for some activities, ... represents a naturally occurring dominant negative form of Meis2 that might be able to interfere by competing with other Meis isoforms for binding to Pbx1, for example. Our attempt...

... Finally, language model integration with RSVP is relatively straightforward, as we shall demonstrate. See Roark et al. (2010) for methods integrating language modeling into grid scanning. 2 RSVP ... sequences shown exceeds the maximum value of 6 for 3 of the symbols. This occurs when the specified letter is mistyped one or more times. For example, for each mistyped non- backspace symbo...

... not enough for the WSD model- ing. The lack of training information leads to a low performance of the supervised methods. 3) With a large-scale training corpus, the un- supervised WSD method has ... mathematical modeling methods can be applied to EP-based WSD methods. This section focuses on the application of the EP concept to WSD, and chooses Bayesian method for the classifier...

... new chart parsing method for Lambek grammars, inspired by a method for D- Tree grammar parsing. The formulae of a Lam- bek sequent are firstly converted into rules of an indexed grammar formalism, ... are used in an Earley-style predictive chart algorithm. The method is non-polynomial, but performs well for practical purposes much better than previous chart m...

... appropriate for TREC style title queries (Lavrenko, 2004). The top 50 returned documents form the basis for all pseudo-relevance feedback, with other parameters tuned separately for the RM and HAL methods. For ... (Bai et al., 2005), the Information Flow method built upon the original HAL largely out- performed RM. We expect that eHAL would pro- vide an even better basis for Infor...

... semantic score accounts for the semantic preference on a given set of lexical categories and a particular syntactic structure for the sentence. Various formulation for the lexical score and ... literatures. Hence, we will concentrate on the formulation for semantic score. 3. Semantic Tagging Canonical Form of Semantic Representation Given the formulation in Eqn. (1), first we...

... available for CoNLL and MUC, the BBN corpus was split at our discretion: sec- tions 03–21 for TRAIN, 00–02 for DEV and 22-24 for TEST. Corpus sizes are compared in Table 1. 2.2 Evaluating NER performance One ... We found that tagging mod- els built on each corpus perform relatively poorly when tested on the others. We therefore present three methods for analysing internal and inter-...
