The influence of domain expertise on visual overviews of spatiotemporal data / Susanne Bleisch in International journal of cartography, vol 3 n° 2 (December 2017)  

Public [article]  inInternational journal of cartography > vol 3 n° 2 (December 2017) . - pp 166-186 Titre : The influence of domain expertise on visual overviews of spatiotemporal data Type de document : Article/Communication Auteurs : Susanne Bleisch, Auteur ; Matt Duckham, Auteur ; Christopher Pettit, Auteur Année de publication : 2017 Article en page(s) : pp 166-186 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] base de connaissances [Termes IGN] base de données spatiotemporelles [Termes IGN] exploration de données géographiques [Termes IGN] géovisualisation [Termes IGN] méta connaissance Résumé : (auteur) Overviews of spatiotemporal data are acknowledged to play an important role in visualization in initiating and supporting geovisualization and exploratory data analysis (EDA). However, relatively little research has focused on the visual overviews themselves, and their potential impacts on EDA outcomes. In a user study, we evaluated the influence of different levels of domain knowledge on the usefulness of four distinct types of static visual overview of spatiotemporal data. Beyond simply orienting users, our results indicate that visual overviews can be important in gaining insights into a data set, for example, in learning about metadata. Although subjects without domain knowledge struggled to judge the quality of their findings, they were as successful at identifying interesting patterns in the data as those with domain expertise. Our results suggest that detailed background knowledge of a data set can actively hinder EDA. Being already familiar with their own data sets, our results highlight the tendency of data experts to disregard findings that do not match their pre-existing domain knowledge. Based on these findings, our conclusions identify a range of potential avenues for future work, including the use of visual overviews that deliberately do not, from first view, reveal the context of the data they show. This later approach could help in cases where domain experts need to see their data with ‘fresh eyes’, and detect interesting patterns in spatiotemporal data before relating the findings to specific knowledge about the data sets and the domain.

Decentralized detection and monitoring of convoy patterns / Jeremy Yeoman in International journal of geographical information science IJGIS, vol 30 n° 5-6 (May - June 2016)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 30 n° 5-6 (May - June 2016) . - pp 993 - 1011 Titre : Decentralized detection and monitoring of convoy patterns Type de document : Article/Communication Auteurs : Jeremy Yeoman, Auteur ; Matt Duckham, Auteur Année de publication : 2016 Article en page(s) : pp 993 - 1011 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Analyse spatiale [Termes IGN] capteur actif [Termes IGN] migration animale [Termes IGN] modèle numérique de déplacement Mots-clés libres : decentralized spatial computing  movement patterns  movement data  convoys  flocks Résumé : (Auteur) This article describes research into the design and analysis of decentralized algorithms for computing convoy patterns (a density-based movement pattern amongst moving point objects, previously formalized and computed in a centralized manner). A series of decentralized algorithms are presented and discussed (naïve, tree-based, and further devolved reactive approaches) for mobile geosensor nodes to share the necessary information to enable in-network detection and monitoring of convoys; these approaches require neither centralized control nor quantitative positioning. Empirical evaluation of algorithm characteristics and performance (via simulation experiments with synthetic and real movement data) demonstrate algorithm efficiency and effectiveness (with various strategies to structure information flow and devolve decision-making considerably improving communication efficiency).

A framework for models of movement in geographic space / Jia Wang in International journal of geographical information science IJGIS, vol 30 n° 5-6 (May - June 2016)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 30 n° 5-6 (May - June 2016) . - pp 970 - 992 Titre : A framework for models of movement in geographic space Type de document : Article/Communication Auteurs : Jia Wang, Auteur ; Matt Duckham, Auteur ; Michael F. Worboys, Auteur Année de publication : 2016 Article en page(s) : pp 970 - 992 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Analyse spatiale [Termes IGN] analyse spatio-temporelle [Termes IGN] granularité (informatique) [Termes IGN] modèle numérique [Termes IGN] objet mobile [Termes IGN] temps instantané Résumé : (Auteur) This article concerns the theoretical foundations of movement informatics. We discuss general frameworks in which models of spatial movement may be developed. In particular, the article considers the object–field and Lagrangian–Eulerian dichotomies, and the SNAP/SPAN ontologies of the dynamic world, and classifies the variety of informatic structures according to these frameworks. A major challenge is transitioning between paradigms. Usually data is captured with respect to one paradigm but can usefully be represented in another. We discuss this process in formal terms and then describe experiments that we performed to show feasibility. It emerges that observational granularity plays a crucial role in these transitions.

GI Expertise / Matt Duckham in Transactions in GIS, vol 19 n° 4 (August 2015)  

Public [article]  inTransactions in GIS > vol 19 n° 4 (August 2015) . - pp 499 – 515 Titre : GI Expertise Type de document : Article/Communication Auteurs : Matt Duckham, Auteur Année de publication : 2015 Article en page(s) : pp 499 – 515 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique [Termes IGN] expertise [Termes IGN] information géographique numérique [Termes IGN] recherche scientifique Résumé : (auteur) This article concerns the identification of the expertise that GI scientists have in common. Rather than attempt to be exhaustive, the approach is to identify a minimal set of expert topics shared across GI science. In this article, a set of five expert topics is proposed for this purpose: structure, uncertainty, dynamism, language and cognition, and design with geographic information. The article then examines the extent to which the literature lends support for these five topics, using two analyses: first, a qualitative analysis of the papers found in the 2006 Classics from IJGIS; and second a citation analysis investigating the occurrences of keywords related to the proposed expert topics. The results suggest that these five areas of expertise do indeed tend to distinguish research in GI science from that in other fields, and in particular where the expert topics occur in combination. The establishment of an acknowledged core of shared expertise should assist in interdisciplinary research and teaching collaboration, usually founded on a shared understanding of what expertise different partners can contribute.
