... summarization (Edmundson, 1969). 4.2 Statistical Learning based Prediction In addition, we take a more general statistical approach to capture the cross-event relations and predict unknown time arguments. ... 4 Approaches Based on these motivations we have developed two approaches to conduct cross-event propaga- tion. Section 4.1 below will describe the rule- based app...

The constraint based encoding of this problem presented in ... the generation process. In constraint programming, the solutions to a constraint satisfaction problem (CSP) are found by alternating propagation with distribution steps. Propagation is a process...

The eval- uation of the prediction models indicate that thoug...

We show that the relevant repetition tendency is based on slow adaptation rather than short-term prim- ing and demonstrate ... the case of lexical priming as a shorter response time in lexical decision making tasks, or as a preference for one syntactic construction over an alternative one in syntactic primi...

Regulation of LAT expression LAT expression is markedly increased upon TCR-med- iated activation; this is inhibited by rapamycin at the translational level. In c...
