It also shows the design and the implementation of a Data Analysis System that provides automation for generating Relationship Graphs of the mobile phone data and the survey answers. The system can be broken into three parts. The system first takes the raw data that are in CVS format to generate Probe Data Packages, which are the data from the mobile phone, and the Survey Data Packages, which are the data from survey answers. The system then takes each of the Probe Data Packages and their corresponding Survey Data Package to generate Formatted Data, which will be further used to create Relationship Graphs. Multiple Relationship Graphs have been generated to demonstrate the results of the experiment and the feasibility of the system from the development perspectives.</dim:field>
