We have summarized 32 functionality-based categories. This is done based on the instances selected from the WT10G corpus. The WT10G corpus is the standard Corpus used in TREC text retrieval conference evaluations. All the instances are carefully annotated manually.
	This is the distribution graph showing the number of instances for each category. For example, there are 264 instances annotated as “Dynamic Banner” class, 62 instances annotated as “Web Application” class, and 5 instances annotated as “Calendar”.
