- 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:
introduction

Context before the citation:
The PICO framework (Richardson et al. 1995) for capturing well-formulated clinical queries (described in Section 2) can serve as the basis of a knowledge representation that bridges the needs of clinicians and analytical capabilities of a system. Third, the paradigm of evidence-based medicine (Sackett et al. 2000) provides a task-based model of the clinical information-seeking process. The Semantic Network provides a consistent categorization of all concepts represented in the UMLS Metathesaurus.

Context after the citation:
The confluence of these many factors makes clinical question answering a very exciting area of research. Furthermore, the need to answer questions related to patient care at the point of service has been well studied and documented (Covell, Uman, and Manning 1985; Gorman, Ash, and Wykoff 1994; Ely et al. 1999, 2005). MEDLINE, the authoritative repository of abstracts from the medical and biomedical primary literature maintained by the National Library of Medicine, provides the clinically relevant sources for answering physiciansâ questions, and is commonly used in that capacity (Cogdill and Moore 1997; De Groote and Dorsch 2003). However, studies have shown that existing systems for searching MEDLINE (such as PubMed, the search service provided by the National Library of Medicine) are often inadequate and unable to supply clinically relevant answers in a timely manner (Gorman, Ash, and Wykoff 1994; Chambliss and Conley 1996).
