Geographic information systems (GIS) are digital technologies for storing, analyzing, and displaying, geographic information. They allow one to reveal the spatial and geographical nature of complex social phenomena through the production of static and dynamic maps. These tools often use data that is quantitative or categorical in nature. They are less well suited for leveraging the richness of information stored in unstructured text data such as interview transcripts, tweets, crime narratives, customer feedback, field notes, or in photographic images.
Computer assisted qualitative data analysis software (CAQDAS) and text analytics techniques have proven more valuable for extracting insightful information from such unstructured sources. They can provide rich details for better understanding complex social phenomena, such as people’s perceptions and interpretations, or reveal hidden factors or unexpected connections underlying those phenomena.
Provalis Research’s QDA Miner and WordStat provide a unique integration of GIS mapping, qualitative analysis and text analytics features, allowing one to relate unstructured text data with geographic information to create maps, timelines, and other graphic displays to enhance your analysis and presentations. The software is equally adept at utilizing location-based data embedded in text, linked with another source or stored separately from the unstructured text.
