Hi,

this all depends on how the data is available. You probably have the words in some kind of list (Excel, CSV, Database)!? You can use the import wizard or the import operators like "Read Database" to import the data into RapidMiner. If you have the words as plain text you need operators from the text processing extension like "Read Document" or "Process Documents from Data". But you will have to provide more details for further help.

Hi,

I'm not really sure about your intention. Do you need the RapidMiner wordlist format? In this case I don't know how to create one instead of creating word vectors by one of the "Process Documents" operators. What do you mean by "help me to say yes"? What classifier do you want to use?

Hi,

i want to creat a matrix with this 600 attribut, if one of them is true, my class(label) is positive else negative...sorry about my english so i didn't find a way to insert all this attribut automaticly. i think that rapidminer word list format can help yes so i tried to instal WVTOOL but i doesn' work with rapidminer 5.1.11 ?

Hi,

creating a wordlist for these words should be possible by writing them into a single document (e.g. one word per line or separated by some other whitespace), importing this to RapidMiner, creating a word vector using "Process Documents" (with tokenization inside). The "Process Documents" operator should deliver the desired wordlist. But I have my doubts, if this will really help you, since your classifier seems only to depend on the word lookup. I'm not sure which approach would make sense and my time is limited at the moment... sorry.

Perhaps someone else may help?

Hi,

It is possible in rapid miner to creat an result attribut who regroup all the attribut with value = Yes


Ex :
ID Label AT1 AT2 AT3 AT4.... (what i need)
row1 : 1 Yes YES NO Yes NO... AT1, AT3
row2 : 2 Yes NO NO Yes NO... AT3*

Please need your help ! thank you very much !
