h1. DOIBoost h2. DOIBoost: Crossref, Unpaywall, Microsoft Academic Graph, ORCID The idea behind DOIBoost and its origin can be found in the paper (and related resources) at: * La Bruzzo S., Manghi P., Mannocci A. (2019) OpenAIRE's DOIBoost - Boosting CrossRef for Research. In: Manghi P., Candela L., Silvello G. (eds) Digital Libraries: Supporting Open Science. IRCDL 2019. Communications in Computer and Information Science, vol 988. Springer, doi:10.1007/978-3-030-11226-4_11 . Open Access version available at: https://doi.org/10.5281/zenodo.1441071 In short, the goal is to enrich the records available on Crossref with what's available on Unpaywall, Microsoft Academic Graph, ORCID intersecting all those datasets by DOI. h3. Inputs * *Crossref*: dump available to Crossref subscribers via MetadataPlus service, updated once a month. * *Micorsoft Academic Graph*: downloaded version on 2021-02-15. We plan to take a latest version on Dec 2021 before MAG will be retired. * *ORCID*: baseline dump obtained in XX/XX/XXXX from URL, regularly updated every week XX XX from the ORCID API available at URL * *Unpaywall*: public database snapshot downloaded in March 2021. Unpaywall updates it twice a year (https://unpaywall.org/products/snapshot) dump published on XX/XX/XXXX. The generation of DOIBoost consists in the following phases: h3. 1 Filter Crossref records that * have blank title * have one of the following publishers: "Test accounts", "CrossRef Test Account" * have no authors with valid names, where valid means: not blank and different from all strings in this list: @List(",", "none none", "none, none", "none &na;", "(:null)", "test test test", "test test", "test", "&na; &na;")@ * have "Addie Jackson" as author and "Elsevier BV" as publisher (empirically we say they are test records) h3. 2 Map Crossref links to projects/funders Links to funding available in Crossref are mapped as funding relationships (@result@ -- @isProducedBy@ --> @project@) applying the following mapping: | *funder* | *grant code* | *Link to* | | DOI: {10.13039/100010663, 10.13039/100010661, 10.13039/501100007601, 10.13039/501100000780, 10.13039/100010665} or name: 'European Union’s Horizon 2020 research and innovation program' | series of 4-9 digits in @award@ | Link to H2020 project | | DOI: {10.13039/100011199, 10.13039/100004431, 10.13039/501100004963, 10.13039/501100000780} | series of 4-9 digits in @award@ | Link to FP7 project | | DOI: 10.13039/501100000781 OR name: 'European Union's'| series of 4-9 digits in @award@ | Link to FP7 or H2020 project | | DOI: 10.13039/100000001 | @award@ | Link to NSF project | | DOI: 10.13039/501100001665 OR name: {'The French National Research Agency (ANR)', 'The French National Research Agency'} | @award@ | Link to ANR project | | DOI: 10.13039/501100002341 | @award@ | Link to Academy of Finland project | | DOI: 10.13039/501100001602 | @award@, removing the initial 'SFI' if present | Link to SFI project | | DOI: 10.13039/501100000923 | @award@ | Link to ARC project | | DOI: 10.13039/501100000038 | @award@ ignore: we cannot map the project codes in Crossref to project codes in OpenAIRE | Link to NSERC (@unidentified@ project) | | DOI: 10.13039/501100000155 | @award@ ignore: we cannot map the project codes in Crossref to project codes in OpenAIRE | Link to SSHRC (@unidentified@ project) | | DOI: 10.13039/501100000024 | @award@ ignore: we cannot map the project codes in Crossref to project codes in OpenAIRE | Link to CIHR (@unidentified@ project) | | DOI: 10.13039/501100002848 OR name :'CONICYT, Programa de Formación de Capital Humano Avanzado' | @award@ | Link to CONICYT project | | DOI: 10.13039/501100003448 | series of 4-9 digits in @award@ | Link to GSRT project | | DOI: 10.13039/501100010198 | @award@ | Link to SGOV project | | DOI: 10.13039/501100004564 | series of 4-9 digits in @award@ | Link to MESTD project | | DOI: 10.13039/501100003407 | @award@ | Link to MIUR project.

Each journal comes with its International Standard Serial Numbers (issn, eissn, lissn) and, when available, a flag that tells if the journal is open access. The intersection is done on the basis of the International Standard Serial Numbers. The records with a @journal.[l|e]issn@ that match are enriched as follows: * Each instance gain the @hostedby@ information. * If the journal is open access, the access rights of the instances are also set to "Open Access" with "gold" route. The hostedby of records that do not match are set to the "Unknown Repository".
