I am not sure I understand your query, it looks like it may be a
Categorical Regression or even an ordinary Multiple Regression application.
At this superficial look it appears that your data could be translated
to a statistical package such as SPSS.
It appears that you want to predict a continuous variable rather a
nominal level one so I don't see it as a classification problem.
Do you have a limited set of words that applies to every case? "top"
"10" . . . ? with values yes and no or yes/no/does not apply?
How many cases (entities, records, lines) do you have in your data set?
How many variables (attribute fields, columns)) to you want to use as
predictors? Do you have the one nominal level predictor (publication)
and 6 dichotomous predictors only?
How many different values does the variable "publication" have?
What does "sales conversion" rate mean?
Why do you think having these words in the article field would be
predictive of sales conversion?
