Hello together, 

i have a nominal attribute title which contains a text description and between the text description the year (4 digits). Sometimes there are also some other digits in the text. So i have to search for "4 digits within the text" and generate a new attribute for year. 

Example: 

title = "that is the 1st test attribute 2019 but not the last one."

Now i want to extract the year of the title attribute. 

Year = 2019 

I tried it first with regex and the Replace operator with the regex  "\d{4}" but i only could replace the digits and not extract into a new attribute. 

Can someone please help me or give an idea how to solve this issue. 

Thank you in advance, i am a newbie to rapidminer. 

Best, 
Chris

    Hi Chris @sirhc
    You almost had it.  The missing piece was to use a so-called capturing group in your replace-what parameter (round brackets) and use the number of the capturing group in the replace-by parameter with a dollar sign.
    Replace-what: .*(\d{4}).*
    Replace-by: $1
    The process below shows a simple example.  Please note that it uses the last occurrence of a year in case there are multiple years.  If there is no year in the title, it returns the complete title instead.
    Hope this helps,

    Hi Chris,
    The process below takes care of cases without a year (the extracted value is then missing) and calculates the age.
    Hope this helps,

    Hi @sirhc,

    For the example text, we have at least three options.
    Extract Information
    Keep document parts
    Cut document

    Can you give a test of these operators with regex?

    My example process used two of them.

    Hi @yyhuang

    thanks, this was okay but not completely as expected since it needed to be documents first. 

    Hi @IngoRM

    thank you very much. This helped me a lot :smile:
    Is it possible to only take the year and if there is no year in the attribute title i just leave it empty?
    Probably i have to run another Replace Operator and filter for something like that: [a-zA-Z] , right? 

    In the next step i have to generate a new attribute age and calculate the age by today minus the year attribute which i calculated extracted above. Is there a simple way for that? Or just an idea? 

    Thank you very much - you guys helped me a lot. 

    Best Chris

    Hi Chris,
    The process below takes care of cases without a year (the extracted value is then missing) and calculates the age.
    Hope this helps,
    Ingo
