I have a data set in MySQL with two columns "content_id","abstract" like "0001","adddddddidij". Fro every content_id, I want to transform the corresponding abstract into a term vector. I use the operator "Process Documents"but it shows the error "Expected Document but received ExampleSet". I am frustrated by it  and really appreciate the help.  Thx.

    no need to be frustrated  ;)

    The operator "Process Documents", well, does exactly that: It takes a (set of) documents as input and performs the inner operators for preprocessing. Just try the operator "Process Documents from Data" instead which, as the name might imply, does the same but used a data set (example set) as input.
