"problems in tokenizing imported Excel text documents via
I am new to rapidminer, and have been watching videos and reading the postings. Still have the foggist idea, hence this post.
I want to import text from Excel (with each row = a short document), and then tokenize to generate a wordlist. It's simple, but I don't know why I can't get any wordlist by executing the following steps.
1. Read excel (one column with 317 rows, and each row stores a short document)
2. Data to documents
3. Process documents
3a. Tokenize within Process documents
The results:
for the ExampleSet(Process Documents) two columns are shown: first column (Row No.) with 1 to 317, but second column (text), empty.
for the Wordlist (Process Documents) is totally empty.
When I execute steps 1 and 2, it works as I can see the outputs, but not nothing with steps 3 and 3a.
Have been trying in the last two days, so a bit drained, and demoralized as I believe it's a simple problem.
Appreciate if someone can point out my mistake.
Thank you,
George
