-In section~\ref{text_alignment} we present modified common text feature fot text alignment.
-We also compare performance of both the previous and the modified algorithms.
-
+Section~\ref{text_alignment} describes our approach for the text alignment
+(pairwise comparison) subtask. We briefly introduce our system,
+and then we discuss the feature types, which are usable for pairwise comparison,
+including the evaluation of their feasibility for this purpose. We then describe
+the global (corpus-wide) optimizations used, and finally we discuss
+the results achieved and further development.
