Fig. 18.16: Case frame for the verb ‘laugh’.<br />

In fig. 18.16, we presented the description of the world by rectangular boxes,<br />

while the relationship between each of two boxes is done by a relation<br />

represented by an ‘ellipse’.<br />

ATN.<br />

The following points may be noted for describing semantics from an<br />

i) While starting with the sentence S in the ATN, determine the noun<br />

phrase <strong>and</strong> verb phrase to get a representation of the noun <strong>and</strong> the<br />

verb. Bind the noun concept with the subject (agent) of the<br />

corresponding case frame.<br />

ii) While processing the noun phrase, determine the noun; the<br />

singularity/plurality of the article <strong>and</strong> bind marker to noun concept.<br />

iii) While processing the verb phrase, determine the verb. If the verb is<br />

transitive, then find its corresponding noun phrase <strong>and</strong> declare this as<br />

object of the verb.<br />

iv) While processing the verb, retrieve its case frame.<br />

v) While processing the noun retrieve the concept of noun.<br />

The following example illustrates the principle of generating semantic<br />

inferences from a dynamically exp<strong>and</strong>ing ATN.
