These tasks involve navigating through data by panning, zooming in a scale range or switching between different types of geographic information (topographical map, satellite imagery, thematic data, etc.). It uses a large set of data, from various sources and with different representations or resolutions. A mapping application displays a multi-scale map (or pyramid), where each scale (or level) represents a specific level of detail. These levels can present large differences in terms of content and representation (Figure 1), owed to the data heterogeneity, the generalization processes or the symbolization choices. These gaps may disturb or even lose the user while zooming in and out, making sometimes the map navigation cognitively difficult.

Lessons learned from research on multimedia summarization / Guillaume Touya (2015)  

Public Titre : Lessons learned from research on multimedia summarization Type de document : Article/Communication Auteurs : Guillaume Touya , Auteur Editeur : International Cartographic Association ICA - Association cartographique internationale ACI Année de publication : 2015 Conférence : ICA 2015, 18th workshop, Commission on Generalisation and Multiple Representation 21/08/2015 Rio de Janeiro Brésil open access proceedings Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Termes IGN] généralisation automatique de données [Vedettes matières IGN] Généralisation Mots-clés libres : benchmark  evaluation  learning  summarization Résumé : (auteur) [introduction] Map generalization is often considered as a cognitive task similar to text summary. Like text summary, generalization seeks to reduce the level of detail of initial data, highlighting the important features regarding a given need, and preserving the main characteristics of the initial data (Ruas 2002). The automation of text summarization is key research topic for language processing scientists, and it should be interesting to verify if the similarities in the human cognitive process lead to similarities in the automation techniques. Moreover, text summarization is a part of the multimedia summarization problem that also includes video and music summarization, and this complete literature is interesting to review. The aim of the paper is also to identify some guidelines for further map generalization research that can be derived from the multimedia summarization research community. This paper first identifies similarities and differences in both automation problems. Then, section 3 proposes ideas from multimedia summarization that could be beneficial for the map generalization community. Finally, the paper is concluded with some ideas for further research opportunities.
