Texto completoIntegrating them into a federated database system, by describing the precise data meaning in a way both homogeneous between databases and as formal as possible. This precise data meaning is contained in the databases’ content specifications (surveying rules). Method : The general organization of the present specifications follows that of the databases’ schemata, but these schemas are heterogeneous and influenced by implementation problems. To overcome this problem, we suppose that it will be possible to find, in the specifications’ text, a number of common terms referring to shared geographical concepts. All these concepts would constitute what is called a domain ontology. Our idea is not to create a complete ontology but rather a partial, ad hoc one, which would be extended to take new concepts into account as needed. The specifications would then be represented as a bundle of what we call representation procedures, which describe how, given a geographic entity (instance of some geographical concept), one or more representations of this entity are built up into the different databases depending on the nature and the properties of the entity. Thus these procedures describe the links between the ontology and the schemata of the databases. Results : For the example of hydrography in two different IGN databases, BDCarto and BDTopo, our hypothesis seems confirmed : a common ontology could rather easily be defined. Concerning the representation procedures, we were able to establish the main kinds of elementary rules from which they can be constructed. To describe formally these procedures, we then defined a formal language whose grammar has been described in BNF and is based on these elementary rules. Finally, we have made a software prototype, containing a parser for this language, for entering, saving and handling the formal specifications

Texto completoThis PhD thesis deals with topographic databases integration. This process aims at facilitating the use of several heterogeneous databases by making the relationships between them explicit. To automatically achieve databases integration, several aspects of data heterogeneity must be detected and solved. Identifying heterogeneities between topographic databases implies comparing some knowledge about their respective contents. Therefore, we propose to formalise and acquire this knowledge and to use it for topographic databases integration. Our work focuses on the specific problem of topographic databases schema matching, as a first step in an integration application. To reach this goal, we propose to use a specific knowledge source, namely the databases specifications, which describe the data implementing rules. Firstly, they are used as the main resource for the knowledge acquisition process in an ontology learning application. As a first approach for schema matching, the domain ontology created from the texts of IGN's databases specifications is used as a background knowledge source in a schema matching application based on terminological and structural matching techniques. In a second approach, this ontology is used to support the representation, in the OWL 2 language, of topographic entities selection and geometry capture rules described in the databases specifications. This knowledge is then used by a reasoner in a semantic-based schema matching application

Texto completoSome spatial knowledge, current or historical, exists only in the form of text. Examples of such sources of unstructured spatial knowledge include travel guides, historical documents and social media posts. Textual sources contain naturally heterogeneous spatial knowledge: they can be written by different authors, using different vocabulary, from different points of view, they can cover large and diverse geographic areas, and they can contain varied levels of detail. These are some of the reasons why it is difficult to integrate geographic information from textual sources into GIS models, which require highly-structured complete data with direct spatial referencing. The open-world assumption of semantic Web technologies makes knowledge graphs a better solution for modelling and storing geographic information extracted from heterogeneous, incomplete and imperfect natural language text. Structured as a geospatial knowledge graph, what was once ambiguous spatial knowledge can be disambiguated and formally linked to reference geographic resources, thereby enriching it with direct spatial referencing where possible and significantly facilitating its accessibility and reuse.The objective of this thesis is to develop an operational approach for the creation of knowledge graphs from text and geographic reference data that is adapted to the special case of constructing geospatial knowledge graphs that include both direct and indirect spatial referencing. We apply our research to a French text corpus, which allows us to empirically identify and validate a functional methodology for creating geospatial knowledge graphs from text. The corpus is composed of the Instructions nautiques, a series of books published by the Shom that describe the maritime environment and give coastal navigation instructions.The main contribution of this thesis is the ATONTE Methodology for the semi-automatic construction and population of knowledge graphs, geospatial or not, from heterogeneous textual sources, expert knowledge and reference data. We present the ATONTE Methodology in detail and demonstrate how we implemented it to construct a geospatial knowledge graph of the content of the Instructions nautiques.The first of the three components that make up ATONTE is a novel methodology for the manual development of domain ontologies from text and the knowledge of domain experts. We apply this methodology to our corpus, integrating our findings from interviews carried out with expert users of the corpus, to develop the ATLANTIS Ontology: a geospatial seed ontology of the domain of the Instructions nautiques.The second component consists of a baseline approach for automatic nested entity and binary relation extraction from text using a deep neural network. It requires training two existing pretrained deep language models, one for the task of entity extraction and the other for relation extraction, on a domain-specific manually-annotated textual dataset. We implement the approach to extract the spatial entities and relations from our corpus, creating a French-language annotated training dataset in the process. We provide benchmark results for this dataset for three tasks: nested spatial entity extraction, binary spatial relation extraction, and end-to-end spatial entity and relation extraction. The third and final component is dedicated to automatically structuring the information extracted during the previous stage as a knowledge graph according to the ontology developed during the first stage, and disambiguating the entities via entity linking to a reference resource. We present a proof of concept of this stage, using off-the-shelf tools to first structure the spatial entities and relations extracted from the Instructions nautiques according to the ATLANTIS Ontology and then link the entities to their corresponding entries in the BD TOPO®. The result is an operational basis for the geospatial ATLANTIS Knowledge Graph of the Instructions nautiques

Texto completoNowadays, the volume of data coming from the public sector is growing rapidly on the Open Data Web. Most of data come from governmental agencies such as Statistical and Mapping Agencies. Together, these public institutions publish geo-coded statistics that are of utmost importance for policy-makers to conduct various analyses upon their jurisdiction, in time and space. However, through times, all over the world, the subdivisions of such ju- risdictions (portions of space on Earth) delimited by or, under the control of human groups (e.g., administrative or electoral areas) are subject to change: their names, belonging or boundaries change for political or administrative reasons. Likewise, the Territorial Statistical Nomenclatures (TSNs) that are sets of artifact areas (although they usually correspond to political or administrative structures) built by Statistical Agencies to observe a territory at several levels (e.g., regions, districts, sub-districts) also change over time. Changes in TSNs are an obstacle to maintain the comparability of socio-economic data over time, unless past data are recalculated according to present geographic areas, a complicated process that, in the end, hide the territorial changes. Then, territorial changes lead to breaks in the statistical series, and are sources of misinterpretations of statistics, or statistical bias when not properly documented. Therefore, solutions for representing different versions of TSNs, and their evolution on the Open Data Web are to be proposed in order to enhance the understanding of territorial dynamics.In this thesis, we present the Theseus Framework with reference to philosophical issue raised by the Ship of Theseus that, according to legend, was rebuilt entirely over the years, every plank of the ship being replaced one by one. This software framework adopts Semantic Web technologies and Linked Open Data (LOD) representation for the description of the TSNs’ areas, and of their changes: this guaranties the syntactic and, moreover, semantic interoperability between systems exchanging TSN information. Theseus is composed of a set of modules to handle the whole TSN data life cycle on the LOD Web: from the modeling of geographic areas and of their changes, to the exploitation of these descriptions on the LOD Web. All the software modules rely on two ontologies, TSN Ontology and TSN-Change Ontology, we have designed for an unambiguous description of the areas in time and space, and for the description of their changes. In order to automate the detection of such changes in TSN geospatial files, Theseus embeds an implementation of the TSN Semantic Matching Algorithm that computes LOD semantic graphs describing all the TSN elements and their evolution, based on the vocabulary of the two ontologies.This framework is intended first for the Statistical Agencies, since it considerably helps in complying with Open Data directives, by automating the publication of Open Data representation of their geographic areas that change over time. Second, the created LOD graphs enhance the understanding of territorial dynamics over time, providing policy-makers, researchers, general public with semantic descriptions of territorial changes to conduct various analyses upon their jurisdiction, in time and space. The applicability and genericity of our approach is illustrated by three tests of Theseus, each of them being led on three official TSNs: The European Nomenclature of Territorial Units for Statistics (NUTS) (versions 1999, 2003, 2006, and 2010) from the European Eurostat Statistical Institute; The Switzerland Administrative Units (SAU), from The Swiss Federal Statistical Office, that describes the cantons, districts and municipalities of Switzerland in 2017 and 2018; The Australian Statistical Geography Standard (ASGS), built by the Australian Bureau of Statistics, composed of seven nested divisions of the Australian territory, in versions 2011 and 2016

Texto completoThis thesis is in the context of the ANR project GEONTO covering the constitution, alignment, comparison and exploitation of heterogeneous geographic ontologies. The goal is to automatically extract terms from topographic travelogues to enrich a geographical ontology originally designed by IGN. The proposed method allows identification and extraction of terms contained in a text with a topographical connotation. Our method is based on a model that relies on certain grammatical relations to locate these terms. The implementation of this model requires the use of methods or techniques of NLP (Processing of Language). Our model represents the relationships between terms to extract and other elements of the texts that can be identified by using external predefined resources, such as specific lexicons: verbs of travelogue (verbs of displacement, verbs of perceptions, topographical verbs), pre-positions (prepositions of place, adverbs, adjectives), place name, generic thesauri, ontologies of domain (in our case the geographical ontology originally designed by IGN). Once marked by linguistic patterns, the proposed relationships allow us to annotate and automatically retrieve terms. Then various indices help deduce whether the extracted terms evoke topographical concepts. It is through reasoning rules that deductions are made. These rules are based on intrinsic knowledge (evocation of space in the language) and external knowledge contained in external resources mentioned above, or their combination. The advantage of our approach is that the method can extract not only the terms related directly to place name but also those embedded in sentence structure in which other terms coexisted. Experiments on a corpus consisting of 12 travel stories (2419 pages, provided by the library of Pau) showed that our method is robust. As a result, it was used to extract 2173 distinct terms with 1191 valid terms, with a precision of 0.55. This demonstrates that the use of the proposed relationships is more effective than that of couples (term, place name) (which gives 733 distinct terms valid with an accuracy of 0.38). Our method can also be used for other applications such as geographic named entity recognition, spatial indexing of textual documents
