+Table~\ref{t2} shows that there is some difference in classification when
+choosing different parameter sets. The results show that adding the focus word
+is very important knowledge since the percentage increases quite a bit.
+However, knowing only the focus word gives exceptionally low performance.
+
+Knowing the next words or the previous words gives some improvement but not a
+whole lot.
+
+Table~\ref{t1} shows that the method does not make a big difference.
+
+Using ten-fold cross validation decreases the percentage.
