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

6 5 1. Principle of the graph to tree transfer (structural transfer) 1.1 Graph having already a tree structure watch applehe agt obj Graph structure watch applehe agtobj Tree structure

7 6 1.2 A node of the graph has several mother nodes : reverting relations He was watching the falling apple. watch applehe agt obj fall obj Graph structure watch applehe agt obj fall obj Graph structure 1. Principle of the graph to tree transfer (structural transfer)

8 7 1.2 A node of the graph has several mother nodes : reverting relations He was watching the falling apple. watch applehe agt obj fall obj Graph structure watch applehe agtobj fall INV(obj) Tree structure 1. Principle of the graph to tree transfer (structural transfer)

9 8 1.3 Opening a closed circuit. He eats his apple. pos(apple, he(icl>human)) Graph structure Tree structure eat applehe:1 agt obj he:1 pos eat applehe agt obj pos 1. Principle of the graph to tree transfer (structural transfer)

10 9 1.3 Processing a compound UW. Isaac sees that an apple fall and he explains it. Graph structure noun)) agt(see(icl>do),Isaac(icl>proper noun) obj(see(icl>do),:01) explain Isaac agt see agt :01 obj and :01 apple fall obj 1. Principle of the graph to tree transfer (structural transfer) explain Isaac:01 agt see :01 obj and apple fall obj Isaac:01 agt :01 obj Tree structure
