According to https://github.com/mattbierbaum/arxiv-public-datasets/blob/master/arxiv_public_data/regex_arxiv.py#L12 we have much more categories possible. Like for the sub-categories, we might want to simply have a free range of characters?
e.g. instead of

(math|hep|astro|cond|gr|nucl|quat|stat|physics|cs|nlim|q\\-bio|q\\-fin)[a-zA-Z\\-\\.]*

having simply:

[a-zA-Z\\-\\.]*

I am a bit worry then about the robustness of the regex for ill-formed input wrt. catastrophic backtracking as we have seen elsewhere. Maybe best alternative would be to enumerate all the possibilities?

Testing a bit the regex:

  • there is a double ?? in the first component which is a typo I think?
  • better avoid having the captured parenthesis for the sub-term (math|hep|astro|cond|gr|nucl|quat|stat|ph...), we could add a non captured parenthesis
    • I don't understand the [^a-zA-Z] before the (math|hep|astro|cond|gr|nucl|quat|stat|physics|cs|nlim|q\\-bio|q\\-fin), it makes hep-lat/0509026 failing for example as it expects something before the arXiv identifier?

Suggested regex:

(ar[xX]iv\s?(\.org)?\s?\:\s?\d{4}\s?\.\s?\d{4,5}(v\d+)?)|(ar[xX]iv\s?(\.org)?\s?\:\s?[ a-zA-Z\-\.]{3,16}\s?/\s?\d{7}(v\d+)?)|((?:math|hep|astro|cond|gr|nucl|quat|stat|physics|cs|nlim|q\-bio|q\-fin)[a-zA-Z\-\.]*/\d{7}(v\d+)?)

In java syntax:

(ar[xX]iv\\s?(\\.org)?\\s?\\:\\s?\\d{4}\\s?\\.\\s?\\d{4,5}(v\\d+)?)|(ar[xX]iv\\s?(\\.org)?\\s?\\:\\s?[ a-zA-Z\\-\\.]{3,16}\\s?/\\s?\\d{7}(v\\d+)?)|((?:math|hep|astro|cond|gr|nucl|quat|stat|physics|cs|nlim|q\\-bio|q\\-fin)[a-zA-Z\\-\\.]*/\\d{7}(v\\d+)?)

We then have only one captured group for one arXiv identifier.

// regular expression for PubMed identifiers, last group gives the PMID digits
static public final Pattern pmidPattern = Pattern.compile("((PMID)|(Pub(\\s)?Med(\\s)?(ID)?))(\\s)?(\\:)?(\\s)*(\\d{1,8})");
