Keyword Filter and Accuracy

[rileytwo]

Can you elaborate further on the filter and accuracy? On the section concerning the filter, it is mentioned that providing a keyword, say "keyword" will search for pages that include "keyword" at least one time on the page. In the accuracy section following the filter guidelines, it's then said that a 50% accuracy rate means that "keyword" occurs at least once, while 100% means "keyword" occurs at least five times. Is there something I'm not understanding? Webcrawling is a new concept for me, but I still can't seem to make sense of this particular section.

Yes, one occurrence gives 50% and five occurrences gives 100%

Example : D<- " key2 text text text text text text text text text text key1 key1 key1 key1 key1"

• If KeywordsFilter="key1" result is 100%
• If KeywordsFilter="key2" result is 50%
• If KeywordsFilter=c( "key1","key2") result is 75% from 100/2+50/2
• If KeywordsFilter=c( "key1","key2", "key3") result is 50% from 100/3+50/3+0

It's just a strategy that we have implemented in order to handle multiple keyword occurrences. You can use your custom filter function in FUNPageFilter.
