I have about 7000+ rows of data with titles and abstracts (around 20-30 sentences per abstract). I have read it from csv, and column filtered and strings to documents. I have applied taggers and bow creator. Then I wanted to preprocess the documents. However, I get these errors
ERROR Number Filter 0:14 Could not create DocumentBufferedFileStoreCell for document: 8690713e-3
WARN Punctuation Erasure 0:10 Selected document column "Preprocessed Document" could not be found in the input data table.
WARN KNIMEApplication$3 Potential deadlock in SWT Display thread detected. Full thread dump will follow as debug output.
WARN KNIMEApplication$4 Potential deadlock in AWT Event Queue detected. Full thread dump will follow as debug output.
It would be much appreciated how I can fix this or de-route the preprocessing steps.
