Producing Geo-historical Context from Implicit Sources: A Geovisual Analytics Approach
نویسنده
چکیده
Geo-historical context, or GHC, is a contextual setting based on the interconnectedness of phenomena, events, and place across multiple spatial and temporal scales. GHC allows for situations to be understood and reasoned with, often with aid of visual representations such as maps. This paper introduces a conceptual model of GHC that theoretically motivates a Geovisual Analytics application called the Context Discovery Application (CDA), which is also presented. The CDA is designed to aid in the production of geo-historical context by using computational processes to identify and extract potentially relevant context information from heterogeneous, implicit situation information. This information can then be explored through visual interfaces to help users explain and understand the information. A hypothetical humanitarian context analysis case study is used to show how the CDA can be applied to real world problems.

Developing Geo-temporal Context from Implicit Sources with Geovisual Analytics
The key Geovisual Analytics research question addressed in this paper is how knowledge of past situations can be computationally extracted from heterogeneous and implicit information spaces and presented as visual artifacts within an interactive environment to facilitate reasoning about situations from geographic and temporal (or geo-temporal) contextual perspectives. This paper in particular w...
متن کاملA Geovisual Analytic Approach to Understanding Geo-Social Relationships in the International Trade Network
The world has become a complex set of geo-social systems interconnected by networks, including transportation networks, telecommunications, and the internet. Understanding the interactions between spatial and social relationships within such geo-social systems is a challenge. This research aims to address this challenge through the framework of geovisual analytics. We present the GeoSocialApp w...
متن کاملGeovisual analytics to support crisis management: Information foraging for geo-historical context
Information foraging and sense-making with heterogeneous information are context-dependent activities. Thus visual analytics tools to support these activities must incorporate context. But, context is a difficult concept to define, model, and represent. Creating and representing context in support of visually-enabled reasoning about complex problems with complex information is a complementary b...
متن کاملGeovisual analytics framework integrated with storytelling applied to HTML5
The paper considers how the integration between visualization and storytelling can make statistical findings more comprehensible and accessible to the general public. Traditional practices for geovisual analytics methods applied to official statistics require tools for greater user participation and an improved user experience. The approach set out in this paper allows the analyst (the author) ...
متن کاملTowards a Geovisual Analytics Observatory
In response to the charge “How can we best develop a systematic understanding of the intersection between human abilities, cartographic design decisions, and map use context? Can we predict what will work?” I argue for building a geovisual analytics observatory (GeO) to frame and support fundamental investigations based on empirical evidence of the who, what, how, when and why of human inferenc...
