@kerstarno The problem is that the interface takes the input as a single piece of text (ignoring break-lines). If the input is provided with a "." after the title the entities are extracted correctly

Hi @fedenanni,

thanks for having a look into this. I get the point about the line break and the "." making it clearer. So, that's fine in the original use case

However, checking the text you posted above, I've found a few other things, which I am going to list here for the time being, even though they point to different issues. I'll leave it to you to create new entries here on GitHub as needed.

There is one case, for example, where the use of "." as a delimiter is a little tricky: at the end, the text names the designer "Karl v. Appen", where "v." is the abbreviated "von". The tool currently interprets this as "Karl v." and leaves his last name out completely. This only happens when I specify the language as German, by the way. When I specify the language as English, "Karl v. Appen" is recognised correctly.

There are a few other observations when checking the text in English and in German and comparing them. In German, the tool detects:

• The Berliner Ensemble (which it links to the German Wiki, meaning that the page actually doesn't exist, as this would be linked to the English Wiki instead, https://en.wikipedia.org/wiki/Berliner_Ensemble)
• Berliner Ensemble (again, this time without "The", and linking correctly to the German Wiki page)
• Coriolanus is linked to the Wiki page about the person (not sure, if this could be distinguished by the closeness of the name "Shakespeare" to actually be the play?)
• William Shakespeare (correct)
• Bertolt Brecht (correct)
• Paul Dellau (linking to a page that only says that this entry doesn't exist, https://de.wikipedia.org/wiki/Paul_Dellau; and it doesn't seem as if there were an entry for him at all in Wikipedia)
• Manfred Wekwerth (correct)
• Joachim Tenscher (same as for Paul Dellau above, https://de.wikipedia.org/wiki/Joachim_Tenscher)
• Karl v. Appen (interpreted as Karl v., same as for Paul Dellau and Joachim Tenscher, https://de.wikipedia.org/wiki/Karl_v)

In English, the tool detects:

• Berliner Ensemble (correct)
• Coriolanus (correctly detected as the play by Shakespeare)
• "Coriolanus, von William Shakespeare in der Bearbeitung von Bertolt Brecht" (which doesn't lead to anything in Wiki)
  • With this, in English, William Shakespeare and Bertolt Brecht are not detected as entities themselves
• "Buhnenfassung des Berliner Ensemble" (which doesn't lead to anything in Wiki)
• Musik (which leads to a "May refer to" page)
• Paul Dellau (same as in German)
• Regie (which leads to a Wiki page, more of a stub, though, that explains the term, but not necessarily in the way it is meant in this context, where it essentially means the direction of the play)
• Manfred Wekwerth (correct)
• Joachim Tenscher (same as in German)
• Karl v. Appen (same as for Paul Dellau and Joachim Tenscher, even though there is a Wiki page for https://en.wikipedia.org/wiki/Karl_von_Appen)
  • I'm assuming the problem here is that the Wikidata object (https://www.wikidata.org/wiki/Q895513) is always using "von" and never "v.", so that this connection cannot be made; the only part that says "Karl v. Appen" is the file name of the image linked in the Wikidata object

Let's have a chat about these during our meeting later on today.
