Historical collaborative geocoding

The latest developments in digital have provided large data sets that can increasingly easily be accessed and used. These data sets often contain indirect localisation information, such as historical addresses. Historical geocoding is the process of transforming the indirect localisation information to direct localisation that can be placed on a map, which enables spatial analysis and cross-referencing. Many efficient geocoders exist for current addresses, but they do not deal with the temporal aspect and are based on a strict hierarchy (..., city, street, house number) that is hard or impossible to use with historical data. Indeed historical data are full of uncertainties (temporal aspect, semantic aspect, spatial precision, confidence in historical source, ...) that can not be resolved, as there is no way to go back in time to check. We propose an open source, open data, extensible solution for geocoding that is based on the building of gazetteers composed of geohistorical objects extracted from historical topographical maps. Once the gazetteers are available, geocoding an historical address is a matter of finding the geohistorical object in the gazetteers that is the best match to the historical address. The matching criteriae are customisable and include several dimensions (fuzzy semantic, fuzzy temporal, scale, spatial precision ...). As the goal is to facilitate historical work, we also propose web-based user interfaces that help geocode (one address or batch mode) and display over current or historical topographical maps, so that they can be checked and collaboratively edited. The system is tested on Paris city for the 19-20th centuries, shows high returns rate and is fast enough to be used interactively.Comment: WORKING PAPE

A Partnership to Increase Access to Our Nation's Historical Records

The City of Philadelphia, Department of Records, in collaboration with the Free Library of Philadelphia has designed this collaborative project in an effort to link critical historical data collections from across the region, providing access to a broader scope of information to researchers, historians, genealogists, students, and other members of the public. To conduct this project, the partnership is seeking $108,882 over a two year period from this grant award (to be matched by$37,644 in City General Revenues). This project is designed to begin the process of collaboration between these two organizations with two of the library's most critical and historically significant digital collections--the Centennial Exhibition of 1876 Collection and the Historical Images of Philadelphia Collection. Through this project the partners will both integrate metadata and implement new user tools that will enhance end-user access

Pantheon 1.0, a manually verified dataset of globally famous biographies

We present the Pantheon 1.0 dataset: a manually verified dataset of individuals that have transcended linguistic, temporal, and geographic boundaries. The Pantheon 1.0 dataset includes the 11,341 biographies present in more than 25 languages in Wikipedia and is enriched with: (i) manually verified demographic information (place and date of birth, gender) (ii) a taxonomy of occupations classifying each biography at three levels of aggregation and (iii) two measures of global popularity including the number of languages in which a biography is present in Wikipedia (L), and the Historical Popularity Index (HPI) a metric that combines information on L, time since birth, and page-views (2008-2013). We compare the Pantheon 1.0 dataset to data from the 2003 book, Human Accomplishments, and also to external measures of accomplishment in individual games and sports: Tennis, Swimming, Car Racing, and Chess. In all of these cases we find that measures of popularity (L and HPI) correlate highly with individual accomplishment, suggesting that measures of global popularity proxy the historical impact of individuals

First Conference on Disparities and Quality of Care

Summarizes March 2005 discussions on the link between racial/ethnic disparities in health care and the quality of care. Key topics include making the case for action, increasing the patient-centeredness of care, measuring impact, and changing the system

Towards place-based exploration of Instagram: Using co-design to develop an interdisciplinary geovisualization prototype

An abundance of geographic information is hidden within texts and multimedia objects that has the potential to enrich our knowledge about the relationship between people and places. One such example is the geographic information embedded within user-generated content collected and curated by the social media giants. Such geographic data can be encoded either explicitly as geotags or implicitly as geographical references expressed as texts that comprise part of a title or image caption. To use such data for knowledge building there is a need for new mapping interfaces. These interfaces should support both data integration and visualization, and geographical exploration with open-ended discovery. Based on a user scenario on the Via Francigena (a significant European cultural route), we set out to adapt an existing humanities interface to support social and spatial exploration of how the route is perceived. Our dataset was derived from Instagram. We adopted a thinking by doing approach to co-design an interdisciplinary prototype and discuss the six stages of activity, beginning with the definition of the use case and ending in experimentation with a working technology prototype. Through reflection on the process of tool modification and an in-depth exploration of the data encoding, we were better able to understand the strengths and limitations of the data, the tool, and the underlying workflows. This in-depth knowledge helped us to define a set of requirements for tools and data that will serve as a valuable contribution for those engaged in the design of deep mapping interfaces for place-based research

Placenames analysis in historical texts: tools, risks and side effects

International audienceThis article presents an approach combining linguistic analysis, geographic information retrieval and visualization in order to go from toponym extraction in historical texts to projection on customizable maps. The toolkit is released under an open source license, it features bootstrapping options, geocod-ing and disambiguation algorithms, as well as cartographic processing. The software setting is designed to be adaptable to various historical contexts, it can be extended by further automatically processed or user-curated gazetteers, used directly on texts or plugged-in on a larger processing pipeline. I provide an example of the issues raised by generic extraction and show the benefits of integrated knowledge-based approach, data cleaning and filtering
