People use native language to describe the world which surrounds them. Using native language is the most intuitive way to describe things. Possibility of describing the object with the combination of known phrases is the main advantage of the native language. If we examine deeper this form of world’s description we could clearly see that it suffers from ambiguity because of synonyms, homonyms, pronouns or concealed words. To extract the information from written or other recorded sources we need to know not only the meaning (semantics) of the individual expressions, but the context as well. We need to identify the contents on the basis of relationships between expressions. To do so we build up some sort of an intelligent dictionary of expressions in our brains, which we can call knowledge base.
