Can anyone suggest or help me how can I filter out string data with truncated values.
I’m guessing you’re asking how you can filter out rows whose string values in a given column have an ellipsis?
The easiest way, if so, would probably to use the Row Filter node, specifying the regex to match on; there is actually an ellipsis character
… as opposed to three periods
... so you’ll need to determine which to include in your regex.
Yeahh…you can put it that way. Some of the tweets have those elipsis and some arent (You can refer to the image down below). I have been using string manipulation node, row filter node…it works but some data have been missed to be filter out.
I havent try Regex yet, okay @quaeler thank you for the suggestion.
In this case, since we know that the truncated tweets are due to a bug in the Twitter implementation with retweets (see previous discussion here), you might be able to filter based on strings starting with “RT” that are 140 characters long.
Thanks @ScottF for the help. I hope that your KNIME Team Member can fix this bug asap. This will mean so much to me
It is fixed and the fix should go out with the next summer release of KNIME Analytics Platform.
