Description:

Seems grobid will make mistake when a reference has square brackets.

Hi @elonzh !

Unfortunately the two articles given as examples cannot be used as training data - first one is CC BY but non-derivative and the second one is closed access.

If you have the chance to find similar errors in one or two CC-BY articles, don’t hesitate to reference it here 😃

Another error case:

Paper:

[math/0506081] The Dantzig selector: Statistical estimation when $p$ is much larger than $n$

Reference:

I detect reference errors by clustering alignments, and this algorithm is context-free and works great if the page is well-formatted.

Maybe we can integrate the algorithm into Grobid?
