Hi,

i have tokenize and filtered out some words which left only numbers and english words,

then my problem now is i want to extract out both numbers and english words seperately and putting them in different results,

how can i achieve that?

Btw, i'm using text mining tool here, the file is in .txt format and is semi-structured.


Thanks for helping.

    Hi,

    sorry, I did not get your point. Can you give us an example, best of the data before the desired transformation and what you would like to achieve?

    hi, thanks for reply,

    i had solved the problem actually.

    okay i will rephrase my problem here:


    i had a text file, for example : "Bobbie goes to school today in the morning at 8 oclock with his 30 packs of noodles."

    i would like to filter out english words (bobbie, goes, to ... etc) and as well numberings (8, 30)

    but i found that the filter only allow to do one thing only, either english word or numberings,
    but does not allow for filtering both.


    i could not find other way,
    but lastly i load the file 2 times, and do filtering seperately and i got it solved.


    thanks.

    Hi,
    There was similar discussion recently on the community: https://community.rapidminer.com/discussion/55230/how-to-extract-year-from-a-string
    Maybe this can give you some hints.
    Cheers,

    You could have done it in one load also, and use the multiply operator. One port you use to filter 'number style strings', the other to do the opposite. 

    Same outcome of course but only one time dataload.
