Discovering Co-Location Patterns and Rules in Uncertain Spatial Datasets

  • Co-location mining, which focuses on the detection of co-location patterns, is one of the tasks of spatial data mining. A co-location pattern is a set of spatial features frequently located in close proximity of each other. Most previous works are based on transaction-free apriori-like algorithms which use user-defined thresholds and are designed for point objects. Due to the absence of a clear notion of transactions, it is nontrivial to use association rule mining techniques to tackle the co-location mining problem. The approach we propose is based on a grid transactionization of geographic space and can be extended for spatial extended objects. Uncertainty of a feature presence in transactions is taken into account in our model. The statistical test is used instead of global thresholds to detect significant co-location patterns and rules. We evaluate our approach on real and synthetic data. In addition, we explain the data modeling framework which is used on a real dataset of pollutants and childhood cancer cases.
