Component/s: languageidentifier
Fix Version/s: 0.5
- set component and fix version
> Language detection is weak.
> ---------------------------
>
> Key: TIKA-209
> URL: https://issues.apache.org/jira/browse/TIKA-209
> Project: Tika
> Issue Type: Bug
> Components: languageidentifier
> Affects Versions: 0.3
> Reporter: Robert Newson
> Fix For: 0.5
>
>
> in org.apache.tika.utils.Utils the getUTF8Reader method assigns a language
> determination without checking the confidence rating from ICU's
> CharsetDetector.
> Please add a configurable level (0-100);
> if (language != null && match.getConfidence() > THRESHOLD) {
> metadata.set(Metadata.CONTENT_LANGUAGE, match.getLanguage());
> metadata.set(Metadata.LANGUAGE, match.getLanguage());
> }
> Obviously using charset to imply language is generally weak but it would be
> sufficient if the confidence threshold was controlled. Today, the text
> "hello" is tagged as French, for example.
