[Termes IGN] web sémantiqueRésumé : (Auteur) The collection of volunteered geographic information (VGI) is a user-generated content practice to engage a large number of citizens to collectively create geospatial data. Based on the advent of Web 2.0 and the recent increasing popularity of crowdsourcing approaches, VGI has gained the interest of the geoscience community, because of its ability to complement the collection of geographic information coming from traditional sensing technologies. However, the involvement of a crowd of volunteers, potentially untrained or nonexperts, implies that VGI can be of varying quality. Tracing VGI provenance enables the recording of the collection activity; the information about who gathered what, where and when can then be employed to judge the VGI quality. In this paper, we focus on the adoption of a provenance-based Human Computation approach to aggregate and consolidate VGI. We discuss the representation, inference and publication of Human Computation VGI and its provenance. As more and more of those community-based data collection efforts happen on the Web, we propose the adoption of Semantic Web technologies, through employing an ontological formulation to capture provenance and by following Linked Data principles to publish provenance data on the Web.

Chapter 1 (this chapter) introduces the motivation for the research, and the specific problem being addressed, delineates the scope of the research, and defines some of the nomenclature to be used. Finally there is a summary, including the contribution of this research and an overview of the thesis.
Chapter 2 identifies a number of case studies which illustrate some of the major issues involved in currently used digital representations of spatial data. In most of these instances, a significant failure of the logic of the computer representation can occur, albeit in rare circumstances.
Chapter 3 presents a perspective on the history and current status of the field, and reviews some of the alternative approaches that have been, and are being investigated by other researchers. Research into the specific issue of representing the spatial information in computer form is highlighted in this chapter, rather than the larger body of work that concentrates on the mathematical model, some examples of which are included as background information.
Chapter 4 introduces a construct which has potential in addressing and solving the issues. This is named the "regular polytope", and is rigorously defined. The properties are explored, and the space of regular polytopes is shown to be a metric topology, and to be a Boolean algebra. In addition, the regular polytope is shown to be "regular" in the topological sense (see Section 1.4.4). Finally, the issue of detection of overlap and equality is explored, first for the purely integer-based representation, and then for a representation based on rational numbers with a limited range of quotients and divisors.
Chapter 5 addresses the issue of connectivity, which is a critical issue in the storage, query and manipulation of spatial data. In seeking a useful definition, it is found that a single definition is not sufficient to all requirements, so the two most useful (to be known as Ca and Cb)7 are discussed in detail. Finally, these are applied to the regular polytope representation of spatial regions, using the integer and the domain restricted (finite precision) rational representations as defined in Chapter 4.
Chapter 6 discusses alternative approaches to spatial algebra, and relates the functionality of the regular polytope representation to these. The expressiveness of the regular polytope approach is considered in relation to: The regional connection calculus (Randell et al. 1992), The proximity space (Naimpally and Warrack 1970) and the Boolean connection algebra (Stell 1999). Use is also made of the "Egenhofer 9-intersection matrix" in these discussions for comparison purposes. This is followed by a discussion of the richness of the algebra provided in comparison with other possibilities. Finally, the relationship between this work and the constraint database (Kuper et al. 2000) approach is explored.
Chapter 7 presents some alternate data models that could be used to implement the approach in a database management system. For comparison purposes, a brief summary of conventional vertex representation of polyhedra is included. A basic data model for storage of spatial data in regular polytope form is then described. An alternative model, the "approximated polytope", is introduced which, while retaining the rigour of the regular polytope will address some practical issues, using a storage form more closely aligned to the point/line/polygon paradigm. Also included are basic strategies for topological encoding, with a discussion of practical issues raised by these models.
Chapter 8 describes the implementation of a demonstration set of Java classes, intended as a tool for the practical review of the approach. The implementation is described, the test cases illustrated and some of the practical considerations that arose as a result documented. Special reference is made to the significant issue that arises in cadastral applications of the mixture of 2D and 3D definitions. This chapter gives an indication of the further development that is needed for a full implementation, and contains a discussion of the practicalities involved in converting geo-information to the regular polytope form from the conventional vertex representations.
Chapter 9 Revisits the case studies from Chapter 2 to highlight their solutions using the regular polytope.
Chapter 10 contains the conclusions that can be drawn from the research, summarising the findings in terms of the research question and the results obtained. There is scope for further research in this subject area, and this is also identified.
A bibliography of references follows.
Appendix I contains a summary of the definitions, axioms and assumptions used throughout the thesis.
Appendix II contains proofs of assertions that apply to half spaces, as made in the body of the work.
Appendix III contains proofs of assertions that apply to the integer representation of regular polytopes.
Appendix IV contains proofs of assertions that apply to the domain-restricted rational number representation of regular polytopes.
Appendix V contains the header documentation for selected classes and methods from the Java implementation discussed in Chapter 8.
Appendix VI contains the details of the encoding used in the Java demonstration classes.
Appendix VII contains some calculations of data storage requirements that can be expected for the various data models proposed in Chapter 7. Also included, for comparison are some estimated requirements for similar objects to be stored as conventional vertex representations with and without topological encoding.Note de contenu : 1.
