> Key: TIKA-5052
> URL: https://issues.apache.org/jira/browse/TIKA-5052
> Project: Tika
> Issue Type: Task
> Reporter: Tim Allison
> Priority: Major
>
> The recent Arabic ISO issue encouraged me to look again at mojibuster. I've
> spent the last few days curating and improving a train/dev/test corpus
> derived largely from [~jnioche]'s common-crawl html contribution back in
> January 2024(?). The corpus is heavily oversampled for non-ascii and is a
> treasure trove.
> Along the way, I experimented with a hashed byte ngram model, and it seems to
> work much better so far than the earlier naive bayes approach. This model
> also incorporates UTF16 rather than adjudicating a side car wide unicode
> classifier.
> I'll continue to have bots tagging the original html corpus and supplement it
> with other datasets to make training and evaluating new models easier.
> Initial results with a cnn model were promising, but a bit slow without jdk25
> vectorization. I'll likely keep working on that.
> And, of course, we can add more charsets as needed: DOS and ebcdic maybe?
