Something is missing#
The extractor uses several fallbacks to make sure enough text is returned. Content extraction is a tradeoff between precision and recall, that is between desired and undesirable content. Being ready to accept more unwanted text makes it easier to gather more of the relevant text in the output. Here are ways to tackle the issue:
Changing the minimum acceptable length in the settings
Using the more basic baseline or html2txt functions instead (which is also faster)
(see also reported issues with The New Yorker)
Beyond raw HTML#
In such cases the way to go is to use a browser automation library like Playwright. For available alternatives see this list of headless browsers.
Using another download utility (see
pycurl with Python and
curl on the command-line).
Installing the additional download utility
pycurlmanually or using
pip3 install trafilatura[all]can alleviate the problem: another download library is used, leading to different results.
Several alternatives are available on the command-line, e.g.
wget -O - "my_url" | trafilaturainstead of
trafilatura -u "my_url".
Downloads may fail because your IP or user agent are blocked. Trafilatura’s crawling and download capacities do not bypass such restrictions.
Web page no longer available on the Internet#
Download issues can be addressed by retrieving the files somewhere else, i.e. from already existing internet archives like the Internet Archive or the CommonCrawl.
Download first and extract later#
Since the they have distinct characteristics it can be useful to separate the infrastructure needed for download from the extraction. Using a custom IP or network infrastructure can also prevent your usual IP from getting banned.
