# Grant related tasks

3/4 phases of the grant contain citations related tasks.

* [x] Link PID or DOI to archived versions

> As of v2, we have linkage between fatcat release entities by doi, pmid, pmcid, arxiv.

* [ ] URLs in corpus linked to best possible timestamp (GWB)

> CDX API probably good for sampling; we'll need to tap into `/user/wmdata2/cdx-all-index/` - (note: try pyspark)

* [ ] Harvest all URLs in citation corpus (maybe do a sample first)

> A seed-list (from refs; not from the full-text) is done; need to prepare a
> crawl and lookups in GWB. In 05/2021 we did a test lookup of GWB index on the
> cluster. A full lookup failed, due to [map
> spill](https://community.cloudera.com/t5/Support-Questions/Explain-process-of-spilling-in-Hadoop-s-map-reduce-program/m-p/237246/highlight/true#M199059).

* [x] Links between records w/o DOI (fuzzy matching)

> As of v2, we do have a fuzzy matching procedure (yielding about 5-10% of the total results).

* [ ] Publication of augmented citation graph, explore data mining, etc.
* [ ] Interlinkage with other source, monographs, commercial publications, etc.

> As of v3, we have a minimal linkage with wikipedia. In 05/2021 we extended Open Library matching (isbn, fuzzy matching)

* [x] Wikipedia (en) references metadata or archived record

> This is ongoing and should be part of v3.

* [ ] Metadata records for often cited non-scholarly web publications
* [ ] Collaborations: I4OC, wikicite

We attended an online workshop in 09/2020, organized in part by OCI members;

# TODO

* [x] create a first index, ES7 [schema PR](https://git.archive.org/webgroup/fatcat/-/merge_requests/99)
* [x] build API, [spec notes](https://git.archive.org/webgroup/fatcat/-/blob/10eb30251f89806cb7a0f147f427c5ea7e5f9941/proposals/2021-01-29_citation_api.md)
