Singleton: A Role of the Search Engine to Reveal the Existence of Something in Information Space

Abstract

Information is very important to the existence of something. The information space in this case becomes a continuously explored presentation and determines the existence of something. However, that existence must be related to the access tool, the search engine, serving as an intermediary. Not a few search engines have been present, each having different behaviour. This paper reveals the role of search engines based on singleton through logical reasoning and the set concept. While some measurement results have showed how the concept is played by search engines.
