... Saur ´ ı et al., 2004) as an annotation language for temporal markup. TimeML marks time expressions with the TIMEX3 tag, events with the EVENT tag, and tempo- ral links with the TLINK tag. In addition, ... a modular system for automatic temporal annotation that adds time expressions, events and temporal relations to news texts. 1 Introduction The TARSQI Project (Temporal Awar...

With each successive event, the temporal focus is either maintained or shifted, and a temporal ordering ... indefinites, e.g., “a Tuesday”, are tagged without a value. Finally, expressions which are ambiguous without a strongly preferred reading are left without a value. This representation tr...

... attributes associated with events as tagged in the Timebank Corpus. (1) Tense and (2) grammatical aspect are necessary in any approach to temporal ordering as they define both temporal location and structure ... and aspectual class. These imperfect guesses, combined with other linguistic features, are then used in a second stage to classify the temporal re- lationship between two eve...

With a ... structures instead of licensing them: while a context-free grammar without productions licenses nothing, a constraint grammar without constraints would allow everything. A new constraint mus...

... allosteric DNAzyme with dual RNA-cleaving and DNA-cleaving activities is very challenging. We used an in vitro-selected pistol-like (PL) DNAzyme as a DNA scaffold for designing a DNAzyme with dual catalytic ... As compared with PL DNAzyme, DRc DNA- zyme function seemed to have decreased sensitivity to the reaction temperature. DRc DNAzyme exhibited a broad functional range for temperatu...
