Meta File Format #167

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello All,

For those who used "DependencyDFE" or such FEs that uses external file to read 
collected meta data. Can someone point me to a sample file so I can see its 
format? 

I'm using a version of "DependencyMetaCollector" which do seem to require that 
file (created during reading process). Note: I'm using 
ClassificationUnitFeatureExtractor, if that's any important.

Thanks!

Is there a specific reasons you want to see the file format?

If this is a non-lucene Version of a FE it is probably a Java serialized 
version of a FrequencyDistribution.

Questions like this one should be answered on the developers mailing list 
rather than via issue.
The format of these files is FeatureExtractor-specific. Have a look at 
LuceneBasedMetaCollector (write) and LuceneFeatureExtractorBase (read) to get 
an idea how this works for Lucene-based NGram FeatureExtractors.
