Description	This paper describes our approaches for the Plagiarism Detection task of PAN 2013. We present modified three-way search methodology for source retrieval subtask. We introduce new query type – the paragraph based queries. Their purpose is to check some parts of suspicious text in more depth. The other two types of queries are: the keywords based for retrieval of documents concerning the same theme; and the intrinsic plagiarism based for retrieval sources which contain text detected as different, in a manner of writing style, from other parts of the suspicious document. The query execution was controlled by its type and by preliminary similarities discovered during the searches. We discuss 2-tuples snippet similarity measurement for decision making over search result download, which indicates how many neighbouring word pairs coexist in the snippet and in the suspicious document. Our tests indicate advantages setting of snippet similarity threshold. This paper describes our approaches for the Plagiarism Detection task of PAN 2013.
