Home Page of Natural Language Analysis

Abstract:

This is the first stage of Natural Language Analysis (Parsing) which analyzes the syntactic structure of sentences. Parsing not only varifies that sentences are syntactically well formed but also determines their linguistic relations such as subject-verb, verb-object, and noun modifier, the parser provides a framework for semantic interpretation. This is often represented as a parse tree.

Static version of Natural Language Analysis:

This picture shows the sentence that will be derived. When the actual VRML world is viewed, the user can click on the box to get the next animations.

This snapshot shows that the sentence is substituted by noun phase(NP) and verb phase(VP). When the actual VRML world is viewed, the user can see this view by clicking on the view point "view1".

Here the noun phase is substituted by Def and noun. When the actual VRML world is viewed, the user can see this view by clicking on the view point "view2".

Here the verb phase is substituted by verb and noun phase. When the actual VRML world is viewed, the user can see this view by clicking on the view point "view3".

Here the noun phase is substitued by Def and noun. When the actual VRML world is viewed, the user can see this view by clicking on the view point "view4".
