    Hi,

    I'm not really sure what you want...

    BUT! You can always try this regex:
    ([^\s]+\s){500}
    What it does is search for any number of non whitespace characters, followed by a whitespace character, this pattern repeated 500 times. It works on the site http://www.regexplanet.com/simple/index.html at least (credits to Sebastian for the URL  ;) ) !

    Thanks for your answer...

    So i will clarify my problem a little bit...for example:
    Text1.txt (Total: 110 words)
    Text2.txt (Total: 410 words)
    Text3.txt (Tota: 50 words)

    I need Text Files in 50 words blocks...the result should be:
    Text1.txt -> 3 Segments Files: Text1_Seg1.txt (50 words), Text1_Seg2.txt (50 words), Text1_Seg3.txt (10 words) = Total 110 words
    ......

    can i do this with the operator SplitSegmenter or TextSegmenter (TextMining PlugIn)

    Thanks for your answers

    Hi,
    did you try the regular expression above? I don't know why it shouldn't work...
