* 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.

13 6 Alessia Bardi
* *Crossref*: dump available to Crossref subscribers via MetadataPlus service, updated once a month.
14 5 Alessia Bardi
* *Micorsoft Academic Graph*: downloaded version on 2021-02-15. We plan to take a latest version on Dec 2021 before MAG will be retired.
15 7 Alessia Bardi
* *ORCID*: baseline dump obtained in XX/XX/XXXX from URL, regularly updated every week from the ORCID API available at URL
16
* *Unpaywall*: public database snapshot downloaded in March 2021. Unpaywall updates it twice a year (https://unpaywall.org/products/snapshot)

The generation of DOIBoost consists in the following phases:

20 4 Alessia Bardi
h3. 1 Filter Crossref records that
21
22 1 Alessia Bardi
* have blank title
23
* have one of the following publishers: "Test accounts", "CrossRef Test Account"
24
* 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;")@
25
* have "Addie Jackson" as author and "Elsevier BV" as publisher (empirically we say they are test records)
26
27 4 Alessia Bardi
h3. 2 Map Crossref links to projects/funders
28 2 Alessia Bardi
29 4 Alessia Bardi
Links to funding available in Crossref are mapped as funding relationships (@result@ -- @isProducedBy@ --> @project@) applying the following mapping:

h3. 3 Intersect Crossref with Unpaywall by DOI (DOIBoost1)

The records are enriched with 
61
62 1 Alessia Bardi
* TODO: AUTHORS?
63
* one @instance@ with 
64
** the @best_oa_location@ of Unpaywall
65
** @color@ set as follows: @green@ if the host is a repository; @gold@ if the host is publisher and the journal is open access; @hybrid@ if the host is publisher, the journal is not open access but there is a license; @bronze@ if no license is available.

67 4 Alessia Bardi
h3. 4 Intersect DOIBoost1 with ORCID (DOIBoost2)
68 1 Alessia Bardi
69 4 Alessia Bardi
The records are enriched with the ORCID identifiers of their authors
70
71
h3. 5 Intersect DOIBoost2 with Microsoft Academic Graph (DOIBoost3)
72
73
The records are enriched with:
74 1 Alessia Bardi
* abstracts
75
* MAG identifiers of authors
76
* affiliation relationships
77
* subjects (MAG FieldsOfStudy)
78
* conference or journal information (in the @journal@ field) TODO: or @container@, in case of the dump?
79
* [TO BE REMOVED] instances with URL from MAG
80
81 4 Alessia Bardi
h3. 6 Enrich DOIBoost3 with hosting data sources (@hostedby@) and access right information
82
83
In this phase we intersect DOIBoost3 with a dataset composed of journals from OpenAIRE, Crossref, and the ISSN gold list. 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:
84
* Each instance gain the @hostedby@ information. 
85 1 Alessia Bardi
* If the journal is open access, the access rights of the instances are also set to "Open Access" with "gold" route.
86
87
The hostedby of records that do not match are set to the "Unknown Repository".
