\section{Introduction}
-In PAN 2013 competition on plagiarism detection we participated in both the Source Retrieval
-and the Text Alignment subtask. In both tasks we adapted methodology used in PAN 2012\footnote{%

Section~\ref{source_retr} describes querying approach for source retrieval, where we used three different
types of queries. We present a new type of query based on text paragraphs.
-The query execution were controled by its type and by preliminary similarities

discovered during the searches.
Section~\ref{text_alignment} describes our approach for the text alignment
(pairwise comparison) subtask. We briefly introduce our system,
\section{Conclusions}
-We introduces querying strategy with snippet similarity measure which approved to be

+In source retrieval subtask the strategy performed with the second best ratio
of recall to the number of used queries.
We focused our queries on selected parts of text
and on parts with no discovered external similarities.
