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:
Alshawi and Crouch (1992) present an illustrative first-order fragment along these lines and are able to supply a coherent formal semantics for the CLF-QLFs themselves, using a technique essentially equivalent to supervaluations: a QLF is true iff all its possible RQLFs are, false iff they are all false, and undefined otherwise. The denotational semantics of RQLF structures involving instantiated scope and referent metavariables is given in terms of simple interpretation rules that have the effect of interpreting the quantifiers as having the scopes indicated by the lists of indices, and the pronouns as having the interpretation of the instantiation of the metavariable (in these cases at least). QLF formulas containing quantifiers are prefixed by a scoping metavariable which scoping resolution rules instantiate to a list of the indices associated with quantifiers, in an order that indicates the preferred scoping:

Context after the citation:
There are many good things about this approach. It has proved itself amenable to a large-scale implementation of impressive coverage, generality, and relative efficiency (Alsha.wi 1992). It has the theoretically desirable property of monotonicity and, in practice, a large degree of reversibility.
