Ignore FORM tags in HTMLHighlighter

GoogleCodeExporter commented 9 years ago

When using HTMLHighlighter some times boilerpipe keeps some artifacts related 
coming from FORM and LABEL tags.

This can be easily prevented by addding a new ignorable element to TAG_ACTIONS 
map in HTMLHighlighter.java:

TAG_ACTIONS.put("FORM", TA_IGNORABLE_ELEMENT);

Adding FORM as an ignorable element at the highlighter (but not at the 
Extractor itself) has two disadvantages:

1. The highlighted HTML will not be consistent with the TextDocument's content 
information (i.e., it should rather go into DefaultTagActionMap)
2. FORM may span over many otherwise relevant text blocks. Adding FORM as 
TA_IGNORABLE_ELEMENT significantly reduces extraction accuracy (with L3S-GN1, 
avg. token-level F1 goes down by about 5% to 7%).

Could you please give examples (URLs) where boilerpipe fails currently?
Please try the very latest version from trunk, or -- preferably -- the version 
at http://boilerpipe-web.appspot.com/
