Retrieving data based not only on key words is a challenge. We worked on semi-structured data (cultural heritage corpora). Our project aimed at getting the most relevant text-units of documents (sets of sentences, paragraphs, sections, etc.) according to a spatial query. This paper proposes a method to build summarized spatial indexes for text-units based… (More)
This paper deals with Information Extraction and Retrieval in a Geographic oriented Digital Libraries environment. The proposed approach (implemented within PIV 1 prototype) is based on a semantic analysis of digital corpora and free text queries. First, we present requirements and a methodology of semantic annotation for automatic indexing and… (More)
This paper presents the Virtual Itineraries in Pyrenees (PIV) project. Spatial and temporal unified models are proposed to give a formal representation to geographical information. The aim is to improve the access to local cultural and heritage document collections. The models take into account characteristics of heterogeneous human expression modes:… (More)
Natural Language 'schematizes' space; textual geographic information is usually a selection of certain aspects of a referent scene while neglecting others. Thus, an indexing process relying on such information obviously contains some degree of imprecision and uncertainty. The PIV prototype is a GIR system dedicated to geographic evocations tagging,… (More)
In scalable and widely distributed Service-Oriented Architecture (SOA) environments, supervision is necessary to ensure services are behaving as expected and to trigger the corrective actions when needed. More specically, when dealing with distributed and scalable Enterprise Service Bus (ESB), the control of services and their interactions must be… (More)
Corpus resocialization can be achieved through digital revitalizing, i.e., making a corpus available for new users with new uses. We propose a semi-automatic identification of spatial and temporal markers that make up metadata for localized documents. Metadata is then exploited by concrete applications in environments for tourism and teaching.
