Transcript

  1. NETSCITY tutorial – GEOCOLLAB Workshop 2022 Unveiling world scale scientific

    production and collaborations between cities
  2. GEOCOLLAB project Two main research areas: oMarine science (research on

    seaweeds and algae) o Gene editing o Else? Possible sources (what do we already have access to?): o Bibliographic databases (WoS, Scopus, …) o Conference data (to be identified) oResearch Projects data (ERC, ANR, Research in Svalbard…) o Contracts (science-industry partnerships); Patents… o Phd theses (Theses.fr, etc.)
  3. Spatial information • Postal address: 5 cours des Humanités, 93000,

    Aubervilliers, FR • Organisation (without a city field): University of Edinburgh, Scotland, UK (It can be in Roslin or Edinburgh) • Organisation + ROR/Grid ID (Dimensions.ai; OpenAlex) Caltech, https://ror.org/05dxps055 Max Planck Society, https://ror.org/01hhn8329 (with many child institutes)
  4. Existing softwares for bibliometric mapping CiteSpace, Leydesdorff’s programs and Sci2

    Tool o geocoding data at the street level o mapping network data using Google Earth Maps and Yahoo! Maps using KML files From Chen, 2016 A practical guide for mapping Scientific litterature
  5. Bibliographic data – what is the row material we need?

    « CITY, PROVINCE, COUNTRY » city province country Monterotondo RM Italy Milan Italy Rome Italy Khania Greece POSTAL ADDRESSES
  6. Other types of sources: e.g. conference attendance Netconf project With

    B. Bernela & F. Briatte
  7. Map by M. Maisonobe, CNRS. Data: LORD & TAI-NUI

  8. Data processing : 1) Extraction of addresses 1) Geocoding 1)

    Clustering at the urban area/country levels File with bibliographic metadata Sources: Web Of Science, Scopus, or personal files in .csv Input Netscity Outputs • Cartes • Tables • Fichier d’export Context
  9. Many heterogeneities, transliteration issues and data entry errors

  10. Why should we agregate the geocoded data at the urban

    area level? The output of the geocoding process for 2012 Web of Science publications – Québec area
  11. Why should we agregate the geocoded data at the urban

    area level? The output of the geocoding process for 2012 Web of Science publications – London area
  12. The case of Rome

  13. The variable administrative fragmentation of the territory at the world

    level
  14. Methods: grouping into agglomerations Issues ▪ Group together publication sites

    that are in the same urban area. ▪ Globally comparable urban areas, despite very different urban realities ➢ Search for a delimitation adapted to the urban phenomenon ➢ Delimitation by spatial crossing between urban population density and scientific publications’ spatial distribution Maisonobe, Jégou & Eckert, 2018, Delineating urban agglomerations across the world: a dataset for studying the spatial distribution of academic research at city level DOI : 10.4000/cybergeo.29637
  15. None
  16. Counting methods: arbitrating bet. Full & fractional countings References: Van

    Hooydonk, 1997; Gauffriau et al., 2008, Leydesdorff & Park, 2017 • Full: the total number of addresses/urban areas/countries per publications • Fractional: the sum of each fractioned credit totals one (avoiding double counts) → With NETSCITY the reference unit for normalization can be the address, the urban area or the country
  17. Counting methods: arbitrating bet. Full & fractional countings 2 variables

    can be normalised and mapped with NETSCITY 1. Number of publications/projects per geographical entity (the total number geographical entities involved in a publication/project) 1. Intensity of scientific collaboration between geographical entities (the total number of links between the geographical entities involved in a publication/project) For instance, if a given publication stems from three different urban areas, each inter-urban link receives 1/3 as a weight for this publication. More generally, if a publication is co-signed from 𝑛 urban areas, each pair of urban areas (A, B), with A < B, is assigned a value 𝑙 equals to: 1/𝑛(𝑛 − 1)/2 = 2/(𝑛(𝑛 − 1))
  18. Weighted projection method This method is the normalised counting method

    used in the web application NETSCITY (Maisonobe et al. 2019) A variant: « Newman » projection method (2001). See https://toreopsahl.com/tnet/two-mode-networks/ 2-mode 1-mode
