Materialized View Construction Based on Clustering Technique
[chapter]
2014
Lecture Notes in Computer Science
Preserved Fulltext
However the survey work reveals a few attempts to construct materialized views based on attribute similarity measure by statistical similarity function and thereafter applying the clustering techniques ...
In this paper we have proposed materialized view construction methodology at first by analyzing the attribute similarity based on Jaccard Index then clustering methodology is applied using similarity based ...
Based on the similarity between attributes a novel weighted graph based clustering algorithm is proposed to construct the views. Similar attributes are grouped together to form every cluster. ...
