New entry from plain text fails

• Mandatory: I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

The new automatic parser of entries from text fails to extract anything from citations extracted from papers or sites. Here are two examples:

Is there life after Fortnite? An emerging trend in game design brings novelty

Subramony, D., Molenda, M., Betrus, A., and Thalheimer, W. (2014). The Mythical Retention Chart and the Corruption of Dale’s Cone of Experience. Educational Technology, Nov/Dec 2014, 54(6), 6-16.

With the old, manual one at least I can extract the relevant parts and then correct the record. Is it possible to have it back?

Steps to reproduce the behavior:

1. Copy one of the citations above
2. in JR "New entry from plain text"
3. Paste and push "Add to current library"
4. Nothing happens

Thanks!

Also using the example from the page: https://docs.jabref.org/collect/newentryfromplaintext gives "0 entries were parsed from your query" with JabRef 5.1--2020-06-04--7cc5747 (latest available today)

To diagnose the problem I started JabRef.bat --debug from the portable installation. After other errors not directly related to my problem, here is the output when I ask to parse the entry from the example page:

Seems like Grobid (the parser) tries to connect somewhere but the connection is refused. No sign of this need to connect in the documentation. Could it be the Grobid demo server http://cloud.science-miner.com/grobid/? From the browser I can connect to this page without problems.

Thanks for your help!

WE have our own grobid server, but there are also currently some issues. We are trying to investigate this. See also #6587 #6369

Tried various entries from article references, but no one succeeded. Maybe I'm doing something wrong, but don't understand what.
Could be useful for you if I send you all the failed references?
For now I wait for the next official release before testing again.
Thanks!

Thank you for the offer, @crystalfp .
Actually, the root cause is already known, so this would add no new information.

I guess the maintainers already have this on their "radar".

[humbleambition]

Fantastic, you're working on this already then.
Any idea when this is likely to get fixed?

This issue has been inactive for half a year. Since JabRef is constantly evolving this issue may not be relevant any longer and it will be closed in two weeks if no further activity occurs.

As part of an effort to ensure that the JabRef team is focusing on important and valid issues, we would like to ask if you could update the issue if it still persists. This could be in the following form:

• If there has been a longer discussion, add a short summary of the most important points as a new comment (if not yet existing).
• Provide further steps or information on how to reproduce this issue.
• Upvote the initial post if you like to see it implemented soon. Votes are not the only metric that we use to determine the requests that are implemented, however, they do factor into our decision-making process.
• If all information is provided and still up-to-date, then just add a short comment that the issue is still relevant.

Thank you for your contribution!

This issue still happens, at least on macOS and on Windows (not on GNU/Linux).
