Much research has recently been devoted to developing approaches, techniques, and technologies which assist people with navigation within buildings. Routing is an essential technique often requested by users prior to real-time navigation, providing them with appropriate routes within buildings. A survey of the literature reveals indoor routing approaches(More)
Developing a network based on Twitter data for social network analysis (SNA) is a common task in most academic domains. The need for real-time analysis is not as prevalent due to the fact that researchers are interested in the analysis of Twitter information after a major event or for an overall statistical or sociological study of general Twitter users.(More)
When evaluating a network topology, occasionally data structures cannot be segmented into absolute, heterogeneous groups. There may be a spectrum to the dataset that does not allow for this hard clustering approach and may need to segment using fuzzy/overlapping communities or cliques. Even to this degree, when group members can belong to multiple cliques,(More)
Social network analysis and social network visualizations can provide a meaningful statistical and topological understanding of latent communities. However, the majority of current visualization approaches just represent sub-communities as clusters of closely related nodes in a node-link diagram and embed limitations to represent overlapping communities and(More)
Adaptive visualization approaches attempt to tune the content and the topology of information visualization to various user characteristics. While adapting visualization to user cognitive traits, goals, or knowledge has been relatively well explored, some other user characteristics have received no attention. This paper presents a methodology to adapt a(More)
Spatial information in the form of location-based services, spatial queries, geographical information systems, navigation systems and other spatially aware tools have become commonplace in the past decade. This workshop reviews cutting edge research in the area of spatial information science, including navigation and wayfinding, the use of shared spatial(More)
