[Z7 Beta] Random (?) sentences in the outline view

samvimes

Hi all,

when working with this PDF ( https://www.degruyter.com/document/doi/10.1515/9781400856626.159/html188BET靠谱吗), I've noticed that Zotero shows an outline as available, which was already a surprise because Firefox doesn't show an outline for this document.

Apparently there is some automatic outline detection happening (which would be a great feature) that in this case is not very helpful!it just shows some apparently random sentences in the outline view:

Yes, this feature is still experimental, but it will improve over time.Thanks for reporting.

So far I've noticed quite a few cases in which the outline extraction produces somewhat unhelpful results.In this PDF, for example ( https://www.degruyter.com/document/doi/10.1524/9783050060187/html188BET靠谱吗), Zotero just recognizes the PDFs table of contents as chapter headings:

Is it helpful to you if I report all the problems I'm seeing with this feature?

Definitely helpful!

Okay, I'll keep them coming in this case:

In this book ( http://link.springer.com/10.1007/978-3-322-80378-8), the extraction just extracts the book's title:

In this text ( https://www.nomos-elibrary.de/index.php?doi=10.5771/0023-5652-2015-182-78) it just extracts the first sentence and the title:

In another scanned and OCRed book, it just recognizes part of the heading of one chapter title:

In this case, I had removed the first page of the PDF file before generating the outline to obtain this results.

If I keep the first page, here is the result:

Note that it is working nicely in some cases, so it is really useful to have this feature, even if only partially working.

I have found 3 books where I see the problem also.
188BET靠谱吗I have sent them to support@zotero.org.

Another interesting recent OA article: https://doi.org/10.1021/acsami.3c17037
It is extracting some useful bookmarks, but the structure is not recognized:

188BET靠谱吗In an OCRed PDF, Zotero detects some random sentences as Outline:

Maybe it is because I quite often work with OCRed texts, but so far the outline detection feature has rarely been successful for me.
