- 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:
We then use the program Snob (Wallace and Boulton 1968; Wallace 2005) to cluster these experiences. We train the system by clustering the âexperiencesâ of the response-generation methods in addressing requests, where each experience is characterized by the value of the confidence measure employed by a method and its subsequent performance, reflected by precision and recall (Equations (7) and (8), respectively).

Citation Sentence:

Context after the citation:
Figure 8(a) is a projection of the centroids of the clusters produced by Snob into the three most significant dimensions discovered by Principal Component Analysis (PCA)âthese dimensions account for 95% of the variation in the data. The bottom part of Figure 8(b)  Clusters of response-generation methods obtained from the training set: (a) dimensions produced by PCA and (b) sample clusters. shows the (unprojected) centroid values of three of the clusters (the top part of the figure will be discussed subsequently).15 These clusters were chosen because they illustrate clearly three situations of interest.
