Hi,
I am involved in a project which is trying to provide searching and hit
highlighting on the scanned image of historical newspapers. We have an XML
based OCR format. A sample is below. We need to index the CONTENT attribute
of the String element which is the easy part. We would like to be able find
the "hits" within this XML document in order to use the positioning information
to draw the highlight boxes on the image. It doesn't make a lot of sense to
just extract the CONTENT and index that because we loose the positioning
information. My second thought was to make a custom analyzer which dropped
everything except for the content element and then used the highlighting class
in the sandbox to reanalyze the XML document and mark the hits. With the
marked hits in the XML we could find the position information and draw on the
image. Has anyone else worked with OCR information and lucene. What was your
approach? Does this approach seem sound? Any recommendations?
Thanks, Corey
