Hello,
I have a problem with my text pre processing. Maybe anyone can help me :)

My text looks like this:

T-Mobile US Inc. and two regional carriers, General Communication Inc. in Alaska and CT Cube LP in Texas. The order is subject to review by President Barack Obama.
Commodities
Oil futures rose 67 cents to $93.98 a barrel as U.S. crude supplies dropped, while gold for August delivery climbed $8 to $1,405 an ounce.
Europe
European markets finished sharply lower today with shares in London leading the region. The FTSE 100 was down 2.12% while France's CAC 40 was off 1.87% and Germany's DAX fell lower by 1.20%.

I want to remove the URLs from the text. How can I do this?I think filter tokens does not work?! Is the solution Remove Document parts?

I think the solution should look like this rule: if the word starts with http. or www. then delete the word from the text..... (but only the url of the text)



Kind regards

    Hi fokko,

    depending on your setup you might use "Replace" (for example sets) or "Replace Tokens" (for tokenized documents) and use a regex like this: \[\d*\][^\[\]]* to identify all url links from your text input.

    Cheers,
    Helge

    Thanks for your response. But I can´t solve my problem. I don´t understand the regex command. If I want to delete the words from the text which beginn with http. , what is the regex? and what is the configuration for the operator?

    To sovle the problem, my setup only consists of process document from files and then I tried replace for example sets.

    I dont tokenize in my setup. (If I tokenize a URL like www.helpme.com , I would have www help me com. So If I search for www , I cannot delete the complete URL.

    Thank you for comments

    But I have still the problem to implement your help into my process, because I have other operators. The load text doesn´t work for my setup beacuse I have lots of texts.

    The purpose of my process is to find "positive" or "negative" words in text documents (.txt)

    Another question: if I want to filter out any documents with the term  "via twitter. How can I do this? I tried filter examples. My Setup only works for one word, but not for two or a term.

    Hi fokko,

    here is your process with an alternative input chain in it showing you how to attach the filter techniques. It is useful not to convert your data to the example set format too early as this limits your options to filter and replace tokens or documents.

    Thank you a lot. :) Great support Helge

    I tried to add other text filters in this setup. So I want to filter texts with: GROK-126315. How can I implement this? I tried some ways (multiply, the same process again) but it doesn´t work up to now. [ Update: I found a basic way to solve this)

    Besides my implemention of the new input chain doesn´t work

    Hi fokko,

    can you send me a process or provide more information regarding your current issues? If you want to filter more tokens just add another filter to your process (like the one for twitter). You may also set some regular expressions with your filters to reduce the amount of operators.

    Cheers,
    Helge

    The problem is to implement the input chain for the text data. I built the setup but it has an error and I don´t really know how to fix it.
