You will be presented with a citation segment from the section of an NLP research paper, as well as the context surrounding that citation. Classify the intent behind this citation by choosing from one of the following categories:
- Background: provides context or foundational information related to the topic.
- Extends: builds upon the cited work.
- Uses: applies the methods or findings of the cited work.
- Motivation: cites the work as inspiration or rationale for the research.
- CompareOrContrast: compares or contrasts the cited work with others.
- FutureWork: cites the work as a direction for future research.

Your answer should be a single word from the following list of options: ["Background", "Extends", "Uses", "Motivation", "CompareOrContrast", "FutureWork"]. Do not include any other text in your response.

Section Title:
None

Context before the citation:
They proved to be useful in a number of NLP applications such as natural language generation (Iordanskaja et al., 1991), multidocument summarization (McKeown et al., 2002), automatic evaluation of MT (Denkowski and Lavie, 2010), and TE (Dinu and Wang, 2009). Paraphrase tables (PPHT) contain pairs of corresponding phrases in the same language, possibly associated with probabilities. 1http://www.statmt.org/wmt10/

Context after the citation:
One of the proposed methods to extract paraphrases relies on a pivot-based approach using phrase alignments in a bilingual parallel corpus (Bannard and Callison-Burch, 2005). With this method, all the different phrases in one language that are aligned with the same phrase in the other language are extracted as paraphrases. After the extraction, pruning techniques (Snover et al., 2009) can be applied to increase the precision of the extracted paraphrases. In our work we used available2 paraphrase databases for English and Spanish which have been extracted using the method previously outlined.
