> Key: TIKA-3147
> URL: https://issues.apache.org/jira/browse/TIKA-3147
> Project: Tika
> Issue Type: Task
> Reporter: Tim Allison
> Priority: Major
>
> I noticed that "the quick brown fox jumped over the lazy dog" was identified
> as English in tika-eval. However, if I added semi-colons, it was identified
> as Chinese.
> This is in alignment with what I've recently seen on a new batch of technical
> documents that are mostly numbers and abbreviations...these are being
> identified as Chinese.
> Ideally, we'd strip out punctuation while building the models, and while
> running language id.
> As a short term fix, we should at least strip out punctuation during
> detection.
