An evaluative baseline for geo-semantic relatedness and similarity / Andrea Ballatore in Geoinformatica, vol 18 n° 4 (October 2014)  

Public [article]  inGeoinformatica > vol 18 n° 4 (October 2014) . - pp 747-767 Titre : An evaluative baseline for geo-semantic relatedness and similarity Type de document : Article/Communication Auteurs : Andrea Ballatore, Auteur ; Michela Bertolotto, Auteur ; D. Wilson, Auteur Année de publication : 2014 Article en page(s) : pp 747-767 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] intégration de données [Termes IGN] relation sémantique [Termes IGN] requête (informatique) [Termes IGN] système d'information géographique Résumé : (Auteur) In geographic information science and semantics, the computation of semantic similarity is widely recognised as key to supporting a vast number of tasks in information integration and retrieval. By contrast, the role of geo-semantic relatedness has been largely ignored. In natural language processing, semantic relatedness is often confused with the more specific semantic similarity. In this article, we discuss a notion of geo-semantic relatedness based on Lehrer’s semantic fields, and we compare it with geo-semantic similarity. We then describe and validate the Geo Relatedness and Similarity Dataset (GeReSiD), a new open dataset designed to evaluate computational measures of geo-semantic relatedness and similarity. This dataset is larger than existing datasets of this kind, and includes 97 geographic terms combined into 50 term pairs rated by 203 human subjects. GeReSiD is available online and can be used as an evaluation baseline to determine empirically to what degree a given computational model approximates geo-semantic relatedness and similarity.

Towards dynamic behavior-based profiling for reducing spatial information overload in map browsing activity / E. Mac Aoidh in Geoinformatica, vol 16 n° 3 (July 2012)  

Public [article]  inGeoinformatica > vol 16 n° 3 (July 2012) . - pp 409 - 434 Titre : Towards dynamic behavior-based profiling for reducing spatial information overload in map browsing activity Type de document : Article/Communication Auteurs : E.

This leads to the problems of information overload and lengthy map download and render times. In order to address these problems in an effective and unobtrusive manner, the available content must be implicitly filtered and prioritized according to the user’s interests. Personalization of the user’s map elides less relevant information and prioritizes relevant information. The authors previously introduced a novel technique for detailed behavior-based spatial profiling. This article provides an analysis of the technique while exploring the properties of user interactions with a typical Web-based map browsing system. A technique for the automatic identification of specific interaction patterns is introduced and explored in a bid to improve current behavior-based map personalization techniques. The goal of this work is to move towards real-time profiling to support spatial dataset personalization, thus improving the user experience by reducing information overload.

Personalizing map content to improve task completion efficiency / D. Wilson in International journal of geographical information science IJGIS, vol 24 n° 5-6 (may 2010)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 24 n° 5-6 (may 2010) . - pp 741 - 760 Titre : Personalizing map content to improve task completion efficiency Type de document : Article/Communication Auteurs : D.

Users encounter problems of information overload in using interactive maps to complete tasks. This is further exacerbated by device limitations and interaction constraints in increasingly popular mobile platforms. Application developers must then address restrictions related to screen size and limited bandwidth in order to effectively display maps on mobile devices. In order to address issues of user information overload and application efficiency in interactive map applications, we have developed a novel approach for delivering personalized vector maps. Ongoing task interactions between users and maps are monitored and captured implicitly in order to infer individual and group preferences related to specific map feature content. Personalized interactive maps that contain spatial feature content tailored specifically to users' individual preferences are then generated. Our approach addresses spatial information overload by providing only the map information necessary and sufficient to suit user interaction preferences, thus simplifying the completion of tasks performed with interactive maps. In turn, tailoring map content to specific user preferences considerably reduces the size of vector data sets necessary to transmit and render maps on mobile devices. We have developed a geographic information system prototype, MAPPER (MAP PERsonalization), that implements our approach. Experimental evaluations show that the use of personalized maps helps users to complete their tasks more efficiently and can reduce information overload.

Evaluating the benefits of multimodal interface design for compass-a mobile GIS / J. Doyle in Geoinformatica, vol 14 n° 2 (April 2010)

Mobile device limitations, such as small user interface footprint and pen input whilst in motion, result in information overload on such devices and interfaces which are difficult to navigate and interact with. This has become a major issue as mobile GIS applications are now being used by a wide group of users, including novice users such as tourists, for whom it is essential to provide easy-to-use applications. Despite this, comparatively little research has been conducted to address the mobility problem. We are particularly concerned with the limited interaction techniques available to users of mobile GIS which play a primary role in contributing to the complexity of using such an application whilst mobile. As such, our research focuses on multimodal interfaces as a means to present users with a wider choice of modalities for interacting with mobile GIS applications. Multimodal interaction is particularly advantageous in a mobile context, enabling users of location-based applications to choose the mode of input that best suits their current task and location. The focus of this article concerns a comprehensive user study which demonstrates the benefits of multimodal interfaces for mobile geospatial applications.
