In this chapter, we will demonstrate several techniques to isolate relationships between elements of text. Central to this task is the process of parsing. With this process, we will split text into units which typically corresponds to a Part-Of-Speech (POS). Once the text has been parsed, we can isolate any relationships that might exist.
We will start by demonstrating how we can graphically depict parse trees. We will use Stanford GUI tools for this purpose. By being able to graphically visualize a parse tree, we can better understand the relationships found in the tree. Next, we will examine several techniques to parse text using simple text. Parsing text in this manner is more readily used by computers for subsequent analysis as opposed to a graphical representation.
Parent-child relationships are patterned after familial relationships. However...
