Collect XML samples for Research Categories

giorgiosironi commented 5 years ago

Problem / Motivation

Collect sample JATS XML describing possible categories of a journal, in order to inform a data model for them that can work across multiple organizations/publishers/journals.

Tasks

[ ] IJM
[ ] Several Hindawi related (and unrelated) journals
[ ] More please

Clarification needed and assumptions

What is the source of truth for JATS XML, although here is not that important to have a canonical version, even outdated samples could do

fred-atherden commented 5 years ago

Subject areas are defined in JATS inside the element article-categories, using subj-group and subject elements.

IJM use the same model as eLife here, for example:

<article-categories>
<subj-group subj-group-type="display-channel">
  <subject>Research article</subject>
</subj-group>
<subj-group subj-group-type="heading">
  <subject>Methodology</subject>
</subj-group>
<subj-group subj-group-type="heading">
  <subject>Dynamic microsimulation</subject>
</subj-group>
</article-categories>

Hindawi content (going from the samples that we have) only define the article type (rather than any MSA/research subject):

<article-categories>
<subj-group subj-group-type="heading">
  <subject>Research Article</subject>
</subj-group>
</article-categories>

bioRxiv example:

<article-categories>
<subj-group subj-group-type="author-type">
  <subject>Regular Article</subject>
</subj-group>
<subj-group subj-group-type="heading">
  <subject>New Results</subject>
</subj-group>
<subj-group subj-group-type="hwp-journal-coll">
  <subject>Bioinformatics</subject>
</subj-group>
</article-categories>

Difficulty might be that the value of the subj-group-type attribute may change across journals (there is no default).

Going to look into how else this is used in content from the PubMed archive...

fred-atherden commented 5 years ago

To clarify what I mean by

Difficulty might be that the value of the subj-group-type attribute may change across journals (there is no default).

There are essential two categories usually defined in JATS in the article-categories element, the article type, and a subject area (if there is one).

If we take IJM and Hindawi as examples it, the subj-group[@subj-group-type="heading"] has been used to define each - in IJM it states a subject area and in Hindawi it defines a type of article.

giorgiosironi commented 5 years ago

Understanding whether Research Article type is also in the scope of this, whereas Neurosciences type is
You can have multiple MSA for one article, see IJM example
at least in the eLife case, we can have empty subjects so they need to exist before articles are actually added to them
Hindawi, and even in the eLife case, doesn't necessarily have an MSA
you could have an XML input for MSA, but it wouldn't be JATS, rather XML for a single subject
one of the purposes of journal-cms /subjects is to assign non-XML content like blog articles to those as well
multitenancy requirement to be considered
subj-group-type="heading" is not ~static~ consistent across publishers
big question: can we assume there is a mapping from XML values (Cancer Biology) to MSA ids (cancer-biology)?

giorgiosironi commented 5 years ago

Question: is the XML always changed to do a subject change? Assumption: if we can change the XML of articles (including the typesetter side) that undergo a subject change in a reasonable fast way, we could use it as the source of truth

We may model this in Producer then, as the XML that would come out of it would have the new subject and would be ingested in a silent correction or new version. We confirm this happens in all versions (v1, v2).

giorgiosironi commented 5 years ago

Are there any additional categories added to an article that are not in an XML? In the eLife case no.

Worth mentioning that JATS 1.2 added attributes for such IDs.

Not really, it's about subjects being more than just a title.

Was a quick note, but "one of", the "normal form" of subjects as independent entities from the articles that use them is clear by now.

fred-atherden commented 5 years ago

Here's an example from PLOS bio with numerous child subjects:

Note that this isn't very representative of how many publishers use these elements. From a set of ~1,000,000 articles taken from PMC, 14% (138,000) contain an article-categories element with nested subj-groups.

fred-atherden commented 5 years ago

Of the same 1,000,000 PMC articles, only 1% (11,044) have a subj-group containing more than 1 subject elements. Example (in the subj-group[@subj-group-type="hwp-journal-coll")]:

<article-categories>
    <subj-group subj-group-type="hwp-journal-coll">
        <subject>1014</subject>
        <subject>1009</subject>
        <subject>1011</subject>
        <subject>1053</subject>
    </subj-group>
    <subj-group subj-group-type="heading">
        <subject>Research Articles</subject>
    </subj-group>
    <subj-group subj-group-type="overline">
        <subject>SPECIAL ISSUE: Scaling Effects Regulating Plant Response to Global
            Change</subject>
    </subj-group>
</article-categories>

Of this 1%, only 4,424 contain subj-group[not(@subj-group-type="hwp-journal-coll")] elements with more than one subject, which indicates that the normal capture is for a subj-group element to have only 1 subject (and a possible child subj-group - although in the majority of cases this isn't present).

Possibly noteworthy that subj-group[@subj-group-type="hwp-journal-coll")] is presumably a Highwire press requirement.

fred-atherden commented 5 years ago

Example of the same subject in separate languages (provided by Érudit):

<article-categories>
    <subj-group subj-group-type="heading" xml:lang="en">
        <subject>Front Matter</subject>
    </subj-group>
    <subj-group subj-group-type="heading" xml:lang="fr">
        <subject>Liminaire</subject>
    </subj-group>
</article-categories>

Note @xml:lang is included on the subj-group rather than the subject.

fred-atherden commented 5 years ago

Noting also that there's a JATS element, compound-subject which can be used in place of subject, inside subj-group.

This is not commonly used (627 of the 1,000,000 PMC articles contain it), so unsure whether we want to support it - certainly not needed for MVP (not in IJM, Hindawi or bioRxiv content that we've seen).

Here's an example of it's use:

<article-categories>
    <subj-group subj-group-type="heading">
        <subject>Case Report</subject>
    </subj-group>
    <subj-group subj-group-type="topic">
        <compound-subject>
            <compound-subject-part content-type="code">bjrcr</compound-subject-part>
            <compound-subject-part content-type="label">BJRCR</compound-subject-part>
        </compound-subject>
        <compound-subject>
            <compound-subject-part content-type="code">gen-trct</compound-subject-part>
            <compound-subject-part content-type="label">Genitourinary
                tract</compound-subject-part>
        </compound-subject>
        <compound-subject>
            <compound-subject-part content-type="code">ct</compound-subject-part>
            <compound-subject-part content-type="label">CT</compound-subject-part>
        </compound-subject>
    </subj-group>
</article-categories>

fred-atherden commented 5 years ago

The root article element may have an attribute @article-type. I include this information for completeness, I don't think we need to take this into consideration in this context, but I suppose we could (I don't know how it is currently used for Continuum for example). This attribute has a set of suggested values (provided by the JATS committee), which we should work from if included here.

Example:

<article article-type="research-article">
...
</article>

eLife has the following allowed values - 'article-commentary', 'correction', 'discussion', 'editorial', 'research-article', 'retraction', 'review-article'.
IJM has the following - 'editorial', 'research-article', 'book-review'
Hindawi don't use it (from a small sample of their XML)
bioRxiv use 'article'

thewilkybarkid commented 5 years ago

I don't know how it is currently used for Continuum for example

Don't believe it's used anywhere. (Edit: don't know about the Bot.)

giorgiosironi commented 5 years ago

Thank you for all the examples, I am distilling a checklist in the XML section of https://docs.google.com/document/d/1PmLD6NEiqpjKTnjW-n1Hho_G-znp5lW3ba8PGmOHnQE/edit?ts=5d662f5c#

fred-atherden commented 5 years ago

F1000/Wellcome/Gates open res used nested subj-group element (only to one degree)

Example:

<subj-group>
    <subject>Articles</subject>
    <subj-group>
        <subject>Bioinformatics</subject>
    </subj-group>
</subj-group>

It's a bit strange - all of the parent subj-groups have a <subject>Articles</subject> - the nesting itself, doesn't seem to carry any meaning (as far as I can tell).

giorgiosironi commented 5 years ago

Should this be closed as a duplicate of https://github.com/libero/publisher/issues/256?

fred-atherden commented 5 years ago

@giorgiosironi, yes, the only reason I haven't is because I am unable to (lack the necessary permissions).

giorgiosironi commented 5 years ago

Added you to https://github.com/orgs/libero/teams/elife-developers/members so you should have the same permissions as anyone else now.
