Foundation Of Satistical Natural Language Processing

The book written by Christopher D.Manning and Hinrich Schutze is very difficult to understand . The language of this book is not so easy . I have read WSD ( Word Sense Disambiguation ) chapter of this book and I realized that the language of this book is really tough . If you are a new comer in NLP field then you may not understand all the sentences of this book . I have some knowledge on NLP though I think this book is for advanced learner in NLP . Those who have a profound knowledge in NLP those people only can understand this book . Other chapters are also too difficult to understand ..

Rhetorical Structure Theory

Rhetorical Structure Theory (RST) is basically a relation pattern between two part of a sentence. The main part or clause is known as Nucleus and the secondary part or clause is known as Satellite . now RST defines some relations between satellite and nucleus .

There are four points to remember :

1> Relations

2> Schema

3> Schema Application

4> Structures


Relation definition consists of four fields :

1> Constraints on the nucleus

2> Constraints on the satellite

3> Constraints on the both satellite and nucleus

4> The Effect


some relations are circumstance , contrast , joint , motivation , enablement , sequence etc ...
