Application Of Rough Set Theory In The Research Of Ancient Pottery In Henan Province

Henan province is the birthplace of one of the Chinese nation,its unique geographical environment and a long history of Henan province to achieve a profound cultural heritage.As an important relic of human activity,ancient pottery is an important mark of the early human activities.With the development of human civilization and the progress of the technology,pottery making process is not the same,ancient pottery features such as the shape of objects,texture and patterns of changes in different periods reflects the changes of cultural relics,has a very important research value and significance.Therefore,from the perspective of the types of objects,the use of rough set theory to study the ancient pottery,to explore the different take an examination of the origin and development of classical chemistry has an important theoretical significance and practical value.In this paper,the data mining research of ancient pottery data in Henan province was carried out by rough set theory.Including cans,pots,kettles,Ge,etc.typical artifacts of Henan typical regional culture of ancient pottery database was established according to the related report of archaeological excavation of ancient pottery utensils type data.As part of artifacts incomplete,and in the process of manual recording of the record is not complete,so the construction of the data table is not complete data table.In the process of data preprocessing,for incomplete data is proposed based on incomplete data clustering of missing data imputation method;in the process of attribute reduction,the attribute reduction algorithm based on the important degree of attributes;in the rule extraction process,on the reduction of decision table extraction rules,combined with the archaeology of knowledge analysis of the relationship between heritage and culture.By analyzing the rules in the rule base,it can be concluded that some of the characteristics of the different objects are in line with one of the decision rules,then these artifacts belong to the same cultural area.Research results show that depending on the type of artifacts of ancient pottery data,the rough set method can study different cultural sites of the relationship between,the different test the origin and development of classical chemistry also has certain significance.
