Question 1

dependency tree analysis

Answer 1

a form of analysis, in which we visualize representation where each word depends on exactly one parent, either another word or a dummy root symbol as shown in the figure

Question 2

Answer 2

if we put the words in their linear order, preceded by the root, the edges can be drawn above the words without crossings, or, equivalently, a word and its descendants form a contiguous substring of the sentence.

Question 3

non projective trees
