Extraction of spatio‐temporal data about historical events from text documents / Susanna Abraham in Transactions in GIS, vol 22 n° 3 (June 2018)  

Public [article]  inTransactions in GIS > vol 22 n° 3 (June 2018) . - pp 677 - 696 Titre : Extraction of spatio‐temporal data about historical events from text documents Type de document : Article/Communication Auteurs : Susanna Abraham, Auteur ; Stephan Mäs, Auteur ; Lars Bernard, Auteur Année de publication : 2018 Article en page(s) : pp 677 - 696 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications SIG [Termes IGN] base de données historiques [Termes IGN] histoire [Termes IGN] recherche d'information géographique [Termes IGN] Time-geography [Termes IGN] traitement du langage naturel Résumé : (Auteur) Often, we are faced with questions regarding past events and the answers are hidden in the historical text archives. The growing developments in geographic information retrieval and temporal information retrieval techniques have given new ways to explore digital text archives for spatio‐temporal data. The question is how to retrieve the answers from the text documents. This work contributes to a better understanding of spatio‐temporal information extraction from text documents. Natural language processing techniques were used to develop an information extraction approach using the GATE language processing software. The developed framework uses gazetteer matching, spatio‐temporal relationship extraction and pattern‐based rules to recognize and annotate elements in historical text documents. The extracted spatio‐temporal data is used as input for GIS studies on the time–geography context of the German–Herero resistance war of 1904 in Namibia. Related issues when analyzing the historical data in current GIS are discussed. Particularly problematic are movement data in small scale with poor temporal density and trajectories that are short or connect very distant locations.

Towards a knowledge base to support geoprocessing workflow development / Barbara Hofer in International journal of geographical information science IJGIS, vol 31 n° 3-4 (March-April 2017)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 31 n° 3-4 (March-April 2017) . - pp 694 - 716 Titre : Towards a knowledge base to support geoprocessing workflow development Type de document : Article/Communication Auteurs : Barbara Hofer, Auteur ; Stephan Mäs, Auteur ; Johannes Brauner, Auteur ; Lars Bernard, Auteur Année de publication : 2017 Article en page(s) : pp 694 - 716 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Systèmes d'information géographique [Termes IGN] analyse spatiale [Termes IGN] base de connaissances [Termes IGN] exploration de texte [Termes IGN] flux de données [Termes IGN] opérateur spatial [Termes IGN] service web Résumé : (Auteur) The spatial analysis functionalities of geographic information systems (GIS) are increasingly used across the web. Interface specifications of geoprocessing web services define the syntactic properties of the services (number and type of parameters) and provide textual descriptions of the operations. The discovery and reuse of web services based on these syntactic properties is restricted and has led to the quest for extended operation descriptions. A number of extended operation descriptions have been proposed and are reviewed in this article. The reviewed descriptions focus on particular steps of the workflow development process. In this article we analyse all phases of the development process of a spatial analysis workflow regarding the requirements of operation descriptions. These requirements are translated into a knowledge base that contains information about spatial analysis operations for the operations’ discovery, selection and composition. The knowledge base also foresees the automated discovery of operations in well-defined application contexts such as the transformation of data types or coordinate reference systems. The knowledge base combines the geooperator approach with elements of ontology-based approaches. The geooperator browser is the implementation of the discovery and selection of geoprocessing operations based on the knowledge base. A draft formalization of the knowledge base demonstrates its use and the support it provides during the composition of operations.

Spatial data fusion in spatial data infrastructures using linked data / Stefan Wiemann in International journal of geographical information science IJGIS, vol 30 n° 3-4 (March - April 2016)  

Public [article]  inInternational journal of geographical information science IJGIS > vol 30 n° 3-4 (March - April 2016) . - pp 613 - 636 Titre : Spatial data fusion in spatial data infrastructures using linked data Type de document : Article/Communication Auteurs : Stefan Wiemann, Auteur ; Lars Bernard, Auteur Année de publication : 2016 Article en page(s) : pp 613 - 636 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] données localisées [Termes IGN] fusion de données [Termes IGN] géomatique web [Termes IGN] implémentation (informatique) [Termes IGN] Open geospatial consortium [Termes IGN] standard OGC [Termes IGN] système d'information géographique [Termes IGN] web des données Résumé : (Auteur) The synthesis of spatial data from the various sources available on the Web is a major challenge for current applications based on Web-based information retrieval and spatial decision-making. This article addresses spatial data fusion, with particular emphasis on its application in Spatial Data Infrastructures (SDIs). Possibilities for the integration of SDI and Semantic Web developments in the context of spatial data fusion are reviewed with a focus on the harmonized description and usage of feature relations. Specifically, potential applications of Linked Data principles are discussed in detail. On this basis, a classification and a decomposition of fusion processes in a service-oriented environment are proposed. A prototype implementation demonstrates the feasibility and usability of the approach using Open Geospatial Consortium (OGC) and Semantic Web standards.

Moving code – Sharing geoprocessing logic on the Web / Matthias Müller in ISPRS Journal of photogrammetry and remote sensing, vol 83 (September 2013)  

Public [article]  inISPRS Journal of photogrammetry and remote sensing > vol 83 (September 2013) . - pp 193 - 203 Titre : Moving code – Sharing geoprocessing logic on the Web Type de document : Article/Communication Auteurs : Matthias Müller, Auteur ; Lars Bernard, Auteur ; Daniel Kadner, Auteur Année de publication : 2013 Article en page(s) : pp 193 - 203 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes IGN] architecture orientée services [Termes IGN] réutilisation logicielle [Termes IGN] service web [Termes IGN] traitement d'image Résumé : (Auteur) Efficient data processing is a long-standing challenge in remote sensing. Effective and efficient algorithms are required for product generation in ground processing systems, event-based or on-demand analysis, environmental monitoring, and data mining. Furthermore, the increasing number of survey missions and the exponentially growing data volume in recent years have created demand for better software reuse as well as an efficient use of scalable processing infrastructures. Solutions that address both demands simultaneously have begun to slowly appear, but they seldom consider the possibility to coordinate development and maintenance efforts across different institutions, community projects, and software vendors. This paper presents a new approach to share, reuse, and possibly standardise geoprocessing logic in the field of remote sensing. Drawing from the principles of service-oriented design and distributed processing, this paper introduces moving-code packages as self-describing software components that contain algorithmic code and machine-readable descriptions of the provided functionality, platform, and infrastructure, as well as basic information about exploitation rights. Furthermore, the paper presents a lean publishing mechanism by which to distribute these packages on the Web and to integrate them in different processing environments ranging from monolithic workstations to elastic computational environments or “clouds”. The paper concludes with an outlook toward community repositories for reusable geoprocessing logic and their possible impact on data-driven science in general.
