In this brief paper, a simple and fast computational method, the Planar Visibility Graph Networks Algorithm was proposed based on the famous Visibility Graph Algorithm, which can fulfill converting two dimensional timeseries into a planar graph. The constructed planar graph inherits several properties of the series in its structure. Thereby, periodic series, random series, and chaotic series convert...
The text clustering is one of core problems in text mining and information retrieval field, clustering algorithm is divided into four categories: the partitioned clustering algorithm, the hierarchical clustering algorithm, density-based clustering algorithm, as well as intelligence clustering algorithm. However, most clustering algorithms cannot meet the demand of speed and self-adapting about text...
