Developing FAIR Ontological Pathways: Linking Evidence of Movement in Lidar to Models of Human Behaviour. Journal of Computer Applications in Archaeology, 2020

This computational ontology enables the investigation of movement and its topographic manifestations in the landscape at various spatio-temporal scales. It creates an explicit framework for accessing meaningful information about movement generated through research using both detection and modelling-led approaches. Developing explicit computational frameworks to provide meaningful context is critical, particularly as remote sensing and modelling projects increase in scale and complexity. The process of developing a computational ontology exposes a deeper underlying issue, and one applicable to many topics we address as archaeologists: if we begin to unpack the concept of ‘movement’ it is readily apparent that it is a complex phenomenon, like many human habits, and studying it requires drawing together a variety of types of physical evidence and multiple, often competing, theoretical models of human processes and practices. If we wish to make archaeological ‘data’ on movement available, how do we create appropriate contextual information – really useful metadata – so that this data can be incorporated into the variety of studies for which knowledge of movement is relevant? This is essentially the challenge posed broadly by the FAIR principles, and in particular by the principle of interoperability, which suggests that we “use a formal, accessible, shared, and broadly applicable language for knowledge representation”. Rather than simply seeking to fulfill the requirements of an arbitrary standard, attempting to meet the challenge of interoperability provides an impetus and opportunity to attempt to bridge the gap between data and model, and to reconsider how we conceive and represent knowledge in archaeological digital data and modelling projects. This kind of computational ontology, we suggest, can serve as the key for making the data from both these sources actually FAIR.

It is the outcome of a multidisciplinary analysis. The term « observatory » covers numerous meanings, and many achievements are currently exist under various forms. Our objective is to take advantage of the synergy between scientists with different backgrounds in order to take into account the added value from their scientific expertise. This should help clarify the definition and the basic constitutive principles of such systems. We present our vision of this kind of observatory via a conceptual approach. The scientific device is highlighted and the technical presentation is outlined

Le formalisme " Pollen " est utilisé pour identifier, décrire et localiser les entités géographiques au long de leurs changements. Trois mécanismes de changement sont identifiés et trois concepts proposés: la " généalogie " induisant des liens entre entités géographiques de générations successives, le " mouvement " affectant leur position ou forme, la " vie " traduisant les modifications du contenu de ces espaces.

Knowledge representation techniques such as ontologies are expected to help reducing this gap. Such techniques have already been used in different fields of application, from medical images to landscape pictures. We think they also have a great potential in remote sensing applications due to the interdisciplinary expert knowledge necessary for image interpretation. In this paper, we introduce what are ontologies and we discuss a potential ontological architecture for remote sensing applications. This architecture involves top-domain ontologies (OBOE, SWEET) and domain ontologies (land cover, image, spatio-temporal relations, protocol, sensor). We illustrate our thoughts with an example of Landsat TM image interpretation for detecting beaches.
