7 Conclusion
</SectionTitle>
    <Paragraph position="0"> We have offered a mechanism for the generation of lexical paraphrases of queries posed to an Internet resource. These paraphrases were generated using WordNet and part-of-speech information to propose synonyms for the content lemmas in the queries.</Paragraph>
    <Paragraph position="1"> Statistical information obtained from a corpus was used to rank the paraphrases. Our evaluation shows that paraphrasing improves retrieval performance.</Paragraph>
    <Paragraph position="2"> This is achieved despite mis-tagging and erroneous paraphrasing of co-located words.</Paragraph>
