2018
The "Internet of Things", or IoT, brings to people a brand new approach with a wide range of applications of how we live in this ever changing world. Besides various advantages of IoT that users can benefit from, the downsides of such cyber physical system are often neglected. This paper introduces IoTNegViz, an analytic tool for visualizing possible negative aspects from a cyber physical system in IoT. First, the data is extracted from Twitter, then a natural language processing tool is applied for generating and categorizing keywords. The visualization is utilized for exploring and capturing information in a spatial manner. To evaluate the usefulness and efficiency of IoTNegViz, we conduct a use-case to gather feedback and experience form users.
