How was geography communicated in Diderot and d’Alembert’s Encyclopédie (1751-72)? In this presentation, the interdisciplinary GEODE team will investigate the role of geographical knowledge within this encyclopedia, as part of our larger project to study these themes across French encyclopedias from the eighteenth to the twenty-first centuries. The Encyclopédie consists of 17 volumes of text (~74k articles, or 22M words) and 11 volumes of plates. And yet, the latter contain no maps. Apart from some pages (vol. 5 of plates) related to the “construction of globes” all the geography of the Encyclopédie is contained in the volumes of text. Addressing critics of the approach to the selection of knowledge shared throughout the work in his “Encyclopédie” article (vol. 5 of text), Diderot argues that an Encyclopedia might be seen as “dry”, but that its role is to share geographical knowledge of places that is “scientific”. It should be able to be used to “create good maps”. We take up Diderot’s call, using information retrieval and spatial analysis to create a dataset of all place names in the Encyclopédie, identify historical spatial coordinates as reported in the text, and connect all named places to modern coordinates through entity linking. The resulting dataset allows us to map the Encyclopédie. We explore the spatial coverage of the text, including the outsized representation of certain parts of the world, like France. In addition to this explicit geospatial approach to the data, we use network analysis to explore references to places across articles and volumes. Using such a variety of methods, for the first time, we name, define, classify, and locate, and map places in this key Enlightenment text.

Abstract: This paper describes the methodology for creating GeoEDdA, a gold standard dataset of geo-semantic annotations from entries in Diderot and d’Alembert’s eighteenth-century Encyclopédie.
Aiming to explore spatial information beyond toponyms identified with the commonly used Named Entity Recognition (NER) task, we test the newer span categorization task as an approach for retrieving complex references to places, generic spatial terms, other entities, and relations.
We test an active learning method, using the Prodigy web-based tool to iteratively train a machine learning span categorization model. The resulting dataset includes labeled spans from 2,200 paragraphs.
As a preliminary experiment, a custom spaCy spancat model demonstrates strong overall performance, achieving an F-score of 86.42%. Evaluations for each span category reveal strengths in recognizing spatial entities and persons (including nominal entities, named entities and nested entities).

7th ACM SIGSPATIAL International Workshop on Geospatial Humanities
Following the success of previous editions, this workshop concerns with the use of geographic information systems and other spatial technologies in humanities research, placing an emphasis on new methodologies that leverage the aforementioned technical developments. The standard tools from geographic information systems, as well as more advanced methods such as text- and image-based geographical analysis or spatial simulation, can all benefit from innovative approaches leveraging machine learning, parallel and/or distributed computation, semantic technologies, etc. on humanities sources like archival manuscripts, maps, encyclopedias, newspapers, correspondence collections and more. These kinds of documents pose new challenges for identifying and analyzing spatial information. The workshop aims to bring together researchers and practitioners from different sub-fields of computer science and the geographical information sciences interested in the application of spatial methods and technology to the humanities to discuss how to address these issues in ways that generate new knowledge in multiple disciplines. Participants will demonstrate their contributions and explore how modern GIS and other technologies can inform, and be inspired by, the digital humanities.

Abstract: This paper introduces the Perdido Python library for geoparsing and geocoding French texts. The architecture of the Perdido Geoparser, which includes three layers: back-office, API, and Python library, is outlined. We also provide details on the methods used in the development of the processing chain and the various tasks covered, such as named entity recognition and classification (NERC), and toponym resolution. Lastly, we showcase the different features of the Python library and explain how to use it. The library is built as an overlay using API services, enabling users to manipulate, visualize, and export the results of geoparsing and geocoding. A Jupyter notebook is also provided to demonstrate all the functionalities implemented in the library.

Abstract: The GeoDISCO project aims at studying the major changes in encyclopedic geographical discourse in France between 1751 (when the first volume of the Encyclopédie ou dictionnaire raisonné des sciences, des arts et des métiers, by Diderot and D’Alembert, was published) and today (Wikipedia-France, 2018).
Using linguistic and GIS methods to investigate patterns in geographical content will help us understand why authors deployed language in such ways that use place as a scaffold for ideas and practices. The spatial history of French encyclopedias is a foundation for asking broader questions about the relationship between early modern geographical information and digital geographical resources.

Abstract: Points of interest (POI) are central in many applications such as tourism, itinerary search, crisis management. Cartographic providers usually represent these POI with a spatial entity. However, the description of these entities may significantly vary from one provider to another (e.g., missing properties, outdated information, conflicting values). Spatial entity matching (or record linkage) aims at detecting correspondences between entities referring to the same POI. Most existing approaches have a fixed function for combining similarity measures, thus limiting customization. Besides, evaluating the matching quality is a difficult task since a ground truth dataset cannot be built for all entities and providers. In this paper, we describe GeoAlign, an application that allows fine-grained tuning for spatial entity matching. A merging step is also provided using different strategies. Finally, we propose to estimate the quality of correspondences based on the differences between combination functions and to visualize this estimation in GeoAlign.

Abstract: In this paper we use network analysis to identify qualitative “neighbors” for toponyms in an eighteenth-century French encyclopedia, but could apply to any entry-based text with annotated toponyms. This method draws on relations in a corpus of articles, which improves disambiguation at a later stage with an external resource. We suggest the network as an alternative to geospatial representation, a useful proxy when no historical gazetteer exists for the source material’s period. Our first experiments have shown that this approach goes beyond a simple text analysis and is able to find relations between toponyms that are not co-occurring in the same documents. Network relations are also usefully compared with disambiguated toponyms to evaluate geographical coverage, and the ways that geographical discourse is expressed, in historical texts.

Abstract: Our project involves building a platform able to retrieve, map and analyze the occurrences of place names in fictional novels published between 1800 and 1914 and whose action occurs wholly or partly in Paris. We describe a proof of concept using queries made via the TXM textual analysis platform for the extraction of street names. Then, we propose a fully automatic process using the named entity recognition (NER) components of the PERDIDO platform. This paper describes some encouraging initial results obtained by combining NLP approaches (NER methods) with textometric tools for the automated geoparsing of street names.

Authors: Mauro Gaio, Ludovic Moncla
Abstract: The textual geographical information is frequently or- ganized around spatial named entities. Such entities have intrinsic ambiguities and Named Entity Recognition and Classification methods should be improved in order to handle this problem. This article describes a knowledge-based method implementing a full process with the aim of annotating in a more precise way the spatial information in the textual documents. This gain in accuracy guarantees a better analysis of the spatial information and a better disambiguation of places. The backbone of our proposal is a construction grammar and a cascaded finite-state transducers. The evaluation shows that the introduced concept of hierarchical overlapping, is very helpful to detect a local context associated with Named Entities.

Abstract: Geoparsing and geocoding are two essential middleware ser- vices to facilitate final user applications such as location- aware searching or different types of location-based services. The objective of this work is to propose a method for es- tablishing a processing chain to support the geoparsing and geocoding of text documents describing events strongly lin- ked with space and with a frequent use of fine-grain topo- nyms. The geoparsing part is a Natural Language Proces- sing approach which combines the use of part of speech and syntactico-semantic combined patterns (cascade of transdu- cers). However, the real novelty of this work lies in the geoco- ding method. The geocoding algorithm is unsupervised and takes profit of clustering techniques to provide a solution for disambiguating the toponyms found in gazetteers, and at the same time estimating the spatial footprint of those other fine-grain toponyms not found in gazetteers. The fea- sibility of the proposal has been tested with a corpus of hiking descriptions in French, Spanish and Italian.

Abstract: This paper proposes an approach for the reconstruction of itineraries extracted from narrative texts. This approach is divided into two main tasks. The first extracts geographical information with natural language processing. Its outputs are annotations of so called expanded entities and expressions of displacement or perception from hiking descriptions. In order to reconstruct a plausible footprint of an itinerary described in the text, the second task uses the outputs of the first task to compute a minimum spanning tree.

Abstract: The aim of this work is to find sub-types for Place Named Entities, from the analysis of relations between Place Names and a nominal group within a specific phrasal context. The proposed method combines the use of specific intra-sentential lexico-syntactic relations and external resources like gazetteers, thesauri, or ontologies. It relies on expanded spatial named entities recognition transcribed into a symbolic representation expressed in terms of semantic features. This symbolic representation will then be associated with a geo-coded representation, depending on the available resources. Our method is completely implemented and has been tested on a corpus of travelogues.
