The abstraction of the real world melds the semantics of its objects with the spatial characteristics seamlessly. This is visible in a way the human perceives the real world where it is often difficult to pin point the spatial characteristics of the objects from their semantics. In other words the spatial characteristics are generally hidden with the semantics of the objects. As for example, describing relations of objects the terms near, far or touching are often used which are spatial relations but in general considered as semantic properties which is not true. Hence, it is a trend to consider that the spatial behaviors of objects are parts of its semantics. Similar approaches where the spatial properties are considered as part of semantics have been translated in technical advancements made by the technologies. There is a general trend to mix up spatial components in the semantics or the semantics in the spatial components within technologies. For instance, a classic GIS ignores semantics of objects to focus on the spatial components whereas a non GIS uses spatial components as the semantic parameters of the objects. As the technology is getting matured, it is moving closer to the human perception of the real world. Today, the knowledge management is being researched in real sense to model and to manage knowledge possessed by humans

The emergence of Internet technologies has provided a strong base to share the information in a wider community. As the needs of information have grown it has become necessary to represent them in a proper and meaningful way. It involves attesting semantics to the documents. The major approach to attach semantics to documents involves first to categorize them properly and then to index them with the relevant semantics for efficient retrieval. This categorization and indexing of the Web documents have become important topic for research. These researches focus on the use of knowledge management to structure documents which involves ontologies to conceptualize knowledge of a specific domain. Then, there is knowledge representation which is a vital part of knowledge management. It provides the possibilities to represent knowledge in order to be inferred. Knowledge representations and reasonings have traditionally been a domain within Artificial Intelligence. However, the recent growth in Semantic Web technologies has added fuel to the use of knowledge explicitly in a Web environment. The XML-based knowledge
