Spatiotemporal Network Analysis and Visualization
International Journal of Applied Geospatial Research, 2015Spatiotemporal social network analysis shows relationships among people at a particular time and location. This paper presents an algorithm that mines text for person and location words and creates connections among words. It shows how this algorithm output, when chunked by time intervals, may be visualized by third-party social network analysis ...

Spatiotemporal Modeling and Analysis—Introduction and Overview
KI - Künstliche Intelligenz, 2012Over the past five to seven years the analysis of trajectory data has established itself as an independent research discipline within the area of data mining. In this article we provide an overview on data characteristics, state-of-the-art preprocessing and analysis methods of trajectory data.

Special Issue on Spatiotemporal Modeling and Analysis
KI - Künstliche Intelligenz, 2012Localization technologies such as navigation systems or mobile phones have steadily conquered our everyday life over the past fifteen years. We have become used to knowing exactly where we are. The challenge of today is to know where the others are and where they are going.

A Spatiotemporal Analysis of Arson
Journal of Research in Crime and Delinquency, 2015Objectives: To investigate the characteristics of spatial and temporal patterning of arson incidents in a large urban county. Methods: Using multiyear geocoded crime data from the Los Angeles County Sheriff’s Office (2005 to 2012 ...

Spatiotemporal crowdsourcing behavior: Analysis on OpenStreetMap
2015 Conference on Technologies and Applications of Artificial Intelligence (TAAI), 2015We in this paper explore the user-editing behavior for the crowdsourcing-based OpenStreetMap service. OpenStreetMap, which is an open-sourced web-based map service, have been recognized as the indispensable means in disaster rescue and recovery. Self-motivated contributors may cooperate and share important geographic information to support many ...

As we have suggested many times throughout the book, the general form of an archaeological problem seems to be “why an archaeological site is the way it is?” If we translate it into the spatial domain, we should be asking “where social agents performed their actions and work processes on the basis of the observed relationships between the actual ...

Ranking Regression Analysis of Spatiotemporal Variables
Environment and Planning A: Economy and Space, 1990Socioeconomic systems are often characterized by spatiotemporal structured data sets. If many potentially explanatory variables are available, a ranking of their relevance is desirable. A numerical procedure is presented which allows for a stepwise selective regression analysis of such variables based on least square principles.

Analysis of spatiotemporal patterns in a model of olfaction
Neurocomputing, 2004Abstract We model spatiotemporal patterns in locust olfaction with the dynamic neural filter, a recurrent network that produces spatiotemporal patterns in reaction to sets of constant inputs. We specify, within the model, inputs corresponding to different odors and different concentrations of the same odor.

A severe thunderstorm morphs into a tornado that cuts a swath of destruction through Oklahoma. How do we study the storm’s mutation into a deadly twister? Avian flu cases are reported in China. How do we characterize the spread of the flu, potentially preventing an epidemic? The way to answer important questions like these is to analyze the spatial and
