| Summary: | Mobility data mining in the form of trajectory data mining has been extensively investigated in recent years. Predictive modeling and pattern discovery approaches have been proposed to predict movements and locations, and to extract useful trajectory and location patterns. Nowadays, mobility data consist of not only trajectory data. Mobility data from smart phones include measurements such as call duration/time, call type, digital media consumption, calendar information, apps usage, social interactions, and mobile browsing. These heterogeneous multivariate data allow one to discover interesting and more complex behavioral patterns and rules in terms of space and time.
In this paper, we investigate spatiotemporal rule mining on heterogeneous multivariate mobility data. We propose a systematic approach consisting of three main steps: data fusion, frequent temporal multivariate-location extraction, and rule generation. In particular, we explore the task of extracting multivariate spatiotemporal patterns corresponding to the "where", "when", and "who" queries (and their combinations) related to phone call variables collected from smart phone users. Experimental results on the data from Nokia Mobile Data Challenge is used to show the feasibility and usefulness of our proposed approach. |
