SOCIAL-OBJECTs have three main subclasses: ORGANIZATIONs, SOCIAL-ROLEs, and GEOPOLITICAL-ENTITYs. ORGANIZATIONs constitute one of the major classification systems in the ontology and are based largely on the Standard Industrial Classification Manual (1987). Prominent dimensions for classifying ORGANIZATIONs are for-profit versus nonprofit, private versus public, and service versus manufacturing. Some of the major subtypes of ORGANIZATION are shown in Figure 6 . Most notably, CORPORATIONs are classified under PRIVATE-ORGANIZATIONs.

SOCIAL-ROLEs classify all roles played by HUMANs in our society. They include FAMILY-ROLEs, SERVICE-ROLEs, POLITICAL-ROLEs, RELIGIOUS-ROLEs, GOVERNMENTAL-ROLEs, FINANCIAL-ROLEs, BUSINESS-ROLEs, COMMUNICATION-ROLEs, and so on. It may be noted that SOCIAL-ROLEs indicates the different professions that people take up. The agent of an individual event (such as TEACH) need not always belong to the corresponding SOCIAL-ROLE (such as TEACHER). The SOCIAL-ROLE classification is shown in Figure 7.

The two main subtypes of GEOPOLITICAL-ENTITYs are LARGE-GEOPOLITICAL-ENTITYs and SMALL-GEOPOLITICAL-ENTITYs. the former includes NATIONs, STATEs, PROVINCEs, and REGIONs while the latter includes CITYs, TOWNs, COUNTYs, and DISTRICTs. It may be noted that the onomasticon is most developed under GEOPOLITICAL-ENTITYs. We have instances of concepts such as NATION and CITY that cover most major GEOPOLITICAL-ENTITYs in the world. You may directly map certain lexical entries to such instances when they are available.

Important GEOPOLITICAL-ENTITYs are shown in Figure 8. This completes our tour of all the major kinds of OBJECTs in the ontology. OBJECTs account for more than two thirds of the number of concepts in the ontology.
