Multilanguage OpenCalais like system?

Question

I was very impressed with the OpenCalais system. It's (is/has) a web service where you send your text, they analyze it, then you are provided with a series of categorized (RDF enabled) tags that your document belongs to.

But - at the moment - English is the only supported language.

Do you know of similar systems that handle multilanguage documents? (I'm interested n Italian, but multi language is a plus, of course)

Answer 1

Apache Stanbol can analyze texts in many different languages. So far the following languages are supported (precision and recall values may vary according to the language):

• English,
• 中文 (Chinese),
• Español (Spanish),
• Русский (Russian),
• Português (Portuguese),
• Deutsch (German),
• Italiano (Italian),
• Nederlands (Dutch),
• Svenska (Swedish),
• Dansk (Danish),
• العربية (Arabic),
• עברית (Hebrew),
• 日本語 (Japanese).

The analysis will return the discovered entities. The analysis output format can be:

• JSON-LD,
• RDF/XML,
• RDF/JSON,
• Turtles,
• N-TRIPLES.

Entities, or tagging, of texts can be further tailored according to the system configuration. Ideally any custom vocabulary can be plugged into the system.

There are a couple of demo end-points:

• http://dev.iks-project.eu:8080/enhancer
• http://dev.iks-project.eu:8081/enhancer

Not sure whether all the above languages are supported in the afore-mentioned end-points.

RedLink GmbH is going to provide cloud services based on Apache Stanbol and related software.

The WordLift plugin for WordPress already provides text analysis within WordPress for all the afore-mentioned languages (currently in testing stage). You can try it out installing the plug-in in WordPress and submitting textual contents in the post body.

You can also subscribe and write to the Apache Stanbol mailing list for specific requests or information.

Answer 2

OpenCalais supports both French and Spanish metadata tagging for entities. The set of entities will be extended in future releases. See our online documentation at http://www.opencalais.com/documentation/calais-web-service-api
