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:
Disjunctive feature descriptions are also possible; WIT incorporates an efficient method for handling disjunctions (Nakano, 1991). The domain-dependent knowledge used in this module consists of a unification-based lexicon and phrase structure rules. ISSS also makes it possible for the language generation module to respond in real time because it can output a partial result of understanding at any point in time.

Citation Sentence:
Disjunctive feature descriptions are also possible ; WIT incorporates an efficient method for handling disjunctions ( Nakano , 1991 ) .

Context after the citation:
When a phrase boundary is detected, the feature structure for a phrase is computed using some built-in rules from the feature structure rules for the words in the phrase. The phrase structure rules specify what kind of phrase sequences can be considered as sentences, and they also enable computing the semantic representation for found sentences. Two kinds of sentences can be considered; domain-related ones that express the user's intention about the reser- vation and dialogue-related ones that express the user's attitude with respect to the progress of the dialogue, such as confirmation and denial.
