... grammar: gotol (ql , ~) = q'a; gotol (q,, I~ ) = q,; gotol (q~, noun) = q~; gotol (qs, g) qs; gotol(qs, verb) = ~,; goto~(qs, ~=) = qs; goto, (~, , Po ) = elo; goto, (es, ~) = ... 'natural' syntax trees, generally belong to this subset. For an example, see section 6. 5.2 The automaton To determine the automaton we specify, in addition to the set of states Q,...

... of vertebrate elastic fibers. Furthermore, the elastomeric properties have been related to the capacity to shift from a weakly globular structure to an extended form, mediated by the Pro- and Gly-rich repeats ... and the short pre- dicted secondary structures tend to move along the pri- mary structure (Fig. S1), whereas a helices tend to stretch or to bend. This was confirmed by two...

... time. Finally, we want to relate LMBOT to the STSSG of Sun et al. (2009). To this end, we also introduce the top-down semantics for LMBOT. As expected, both semantics coincide. The top-down semantics ... T ∗ Σ . The finite tree automa- ton M recognizes the tree language L(M) = {t ∈ T Σ | δ(t) ∩ F = ∅} . A tree language L ⊆ T Σ is regular if there exists a finite tree automaton M such tha...

This may seem to be ... of words flagged to nearly zero should raise the precision but lower the recall. The problem is to balance this trade-off to arrive at recall AND precision levels acceptable to...

Selecting words from the network linked to those of the texts makes explicit words related to the same topic as the topic referred by ... very much linked together, we assume that the words of the window belong to two different domains. It means that the window is located across the transition from one topic to a...

Given that we did not have the resources to build an ontology by hand, we decided to use unsupervised methods which cluster words together according to the ... used In addition to the tools and resources previously enumerated, we had to develop some basic tools which one expects to find in any language.
