KeyError: 'Title'

Just tested the python script but got this error:

any idea what could be wrong?

Oh boy. The try-catch used to set the document’s title is off. I will correct it asap. If you know your way around Python, line 278 needs to be removed/commented out. That should do the trick.

pdf-highlights uses the author and title info as given in the PDF’s attributes and includes them in output.txt.

Thanks for the quick answer! I am currently without computer, but I will try as soon as I get it back :)

[ncarboni]

just tried and now it does execute without errors. It does work with PDF highlighted in Devonthink, where I get:

# [](x-devonthink-item://) [🕵️‍♀️](x-devonthink://search?query=)
[](x-devonthink://search?query=)

# Notes

@: Typically crowdsourcing-based approaches to gather annotated data use inter-annotator agreement as a measure of quality. However, in many domains, there is ambiguity in the data, as well as a multitude of perspectives of the information examples. In this paper, we present ongoing work into the CrowdTruth m  

1: The CrowdTruth metrics model the inter-dependency between the three main components of a crowdsourcing system – worker, input data, and annotation. The goal of the metrics is to capture the degree of ambiguity in each of these three components. The metrics are available online at https://github.com/ CrowdTruth/CrowdTruth-core

while, if I highlight something on preview I don't get anything out of it

# [TITLE](x-devonthink-item://) [🕵️‍♀️](x-devonthink://search?query=TITLE)
[AUTHOR](x-devonthink://search?query=AUTHOR)

Questions:

• Do you know how can I resolve the issue?
• in the header of the highlight what exactly should it appears?

Does the PDF has the Title and Author attributes set? That is the info used in printing the first part of the output.

You could either edit the PDF's attributes or add the author's name and title manually to the output. Editing PDF metadata such as these attributes requires Adobe Acrobat, Skim or any other sophisticated PDF tool.

As for the empty output after highlighting something in Preview, that might depend on the color or annotation type. Did you highlight the same text with the same tool in both DT and Preview?

In any case, if you can provide me with the PDF, I can take a look.

[ncarboni]

Ok, the PDF I tried is this one (with the highlighting already in): CrowdTruth 2.0: Quality Metrics for Crowdsourcing with Disagreement (0004) 2.pdf. Now that I see the two different highlight colours side-by-side I wonder if in Mojave or somewhere around high sierra they maybe change the default highlighting colour in preview. I remember it more bright...

Does the PDF has the Title and Author attributes set? That is the info used in printing the first part of the output.

No it didn't. Good point. I was secretly hoping it would take automatically the DT link (e.g. x-devonthink-item://8EB5A5EE-F929-4B10-B7A4-AA27F5A22C33) to the PDF there! But still pretty good! :)

You could either edit the PDF's attributes or add the author's name and title manually to the output. Editing PDF metadata such as these attributes requires Adobe Acrobat, Skim or any other sophisticated PDF tool.

I see I can also add them with DT, but I will try to see if there is a way to automatically embed them when adding the file with a reference manager. Do you do it automatically for each PDF?
