  4. - 1. Principle of the graph to tree transfer - 2. Our tools - 3. Discussion

  5. watch watch obj agt he apple he apple agt obj Graph structure Tree structure 1. Principle of the graph to tree transfer(structural transfer) 1.1 Graph having already a tree structure

  6. watch watch fall fall obj obj obj obj agt agt he he apple apple Graph structure Graph structure 1. Principle of the graph to tree transfer(structural transfer) He was watching the falling apple. agt(watch(icl>do).@entry.@past.@progress,he(icl>human)) obj(watch(icl>do).@entry.@past.@progress,apple.@def) obj(fall(icl>occur).@past.@progress,apple.@def) 1.2 A node of the graph has several mother nodes : reverting relations

  7. watch fall obj obj agt he apple Graph structure 1. Principle of the graph to tree transfer(structural transfer) He was watching the falling apple. agt(watch(icl>do).@entry.@past.@progress,he(icl>human)) obj(watch(icl>do).@entry.@past.@progress,apple.@def) obj(fall(icl>occur).@past.@progress,apple.@def) watch he apple agt obj Tree structure fall INV(obj) 1.2 A node of the graph has several mother nodes : reverting relations

  8. eat eat obj agt he apple he:1 apple pos agt obj he:1 pos 1. Principle of the graph to tree transfer(structural transfer) He eats his apple. agt(eat(icl>do).@entry,he(icl>human)) obj(eat(icl>do).@entry,apple) pos(apple, he(icl>human)) Graph structure Tree structure 1.3 Opening a closed circuit.

  9. explain :01 Isaac:01 explain :01 agt obj fall agt obj fall obj Isaac :01 and and apple agt obj apple see obj Isaac:01 see :01 agt obj Tree structure 1. Principle of the graph to tree transfer(structural transfer) Isaac sees that an apple fall and he explains it. agt(explain(icl>do).@entry,Isaac(icl>proper noun)) obj(explain(icl>do).@entry,:01) obj:01(fall(icl>occur).@entry,apple) and(explain(icl>do).@entry,see(icl>do)) agt(see(icl>do),Isaac(icl>proper noun) obj(see(icl>do),:01) Graph structure 1.3 Processing a compound UW.
