The concept lattice is the structure of dates which is established according to the information in formal context. This structure reveals the nature of the relationship between attributes of the object. It is an effective tool for concept discovery from dates and has been widely used in information retrieval, digital library, software engineering and knowledge discovery. The attribute reduction is important. There are a lot of similarities in the research technique between formal context and topology. This paper tries to watch attribute reduction in concept lattice from the perspective of topology, establishing some connections with subbase reduction in topology. This paper tries to define the restrictions and product of formal context according to the definition of a new topological space, looking whether some topological property can be maintained. Thus the content of formal context has been enriched in some degree.
