In the coming posts a selected set of grammar formalisms are briefed.
These formalisms have been applied to the Arabic language. Projects that are
claimed to have wide coverage over the Arabic grammar by their writers are listed.
Most of the rule based and some of the corpus based projects with their
formalisms are selected to be briefed.
2.1. Overview
The most complex task that a natural language parser has to
perform is syntactic analysis. The two main parts of the syntactic analysis
component of a parser are the grammar and the parsing algorithm. The grammar
encodes the linguistic rules and specifies how each sentence is constructed
from its parts. The parsing algorithm applies the defined rules by the grammar
to a given input. The output scheme defines the format of the parser’s output.
Grammar can be characterized and compared in many different ways. Two
characterizing factors are presented in the next section. The first depends on
linguistic properties and the other comes from processing perspective. Briefs
for the most well-known formalisms that have been successfully applied are
presented in the coming posts.
