     2
     3=== What? ===
     4
     5- reveal and describe relationships among words
     6  - on various levels:
     7    - noun, verb prepositional phrases, clauses
     8    - dependency relation
     9 
     10
     11=== Why? ===
     12
     13- syntactic units are carriers of meaning
     14  - e.g. "in the city"
     15    - meaning of "in", "the" is unclear, or very complicated
     16    - meaning of "in the city" is simply "where"
     17  - usable for mining information, question answering
     18
     19
     20=== How? ===
     21
     22- prerequisites
     23  - morphological information (e.g. part of speech, number, gender)
     24  - lexical semantic information (e.g. "pregnant" goes with women only)
     25- statistical methods
     26  - annotated corpus -> inference of rules
     27  - hard to customize
     28- rule-based methods
     29  - hard to develop and maintain the grammar information
     30  - easy to customize
     31
     32... to be continued
