Today we’re pleased to announce the launch of Rosette API version 1.5!

Updates include new targeted relationship extraction (replacing the previous “open” relationship extraction), changes to entity linking and extraction,  improved text embeddings, and expanded support for Chinese, Japanese, Korean, and Vietnamese, including sentiment analysis for Japanese text (beta).

What’s new?

 

Targeted Relationships

The /relationships endpoint now returns targeted relationships, specific relationships that connect two entities (think “Bill Gates was educated at Harvard). Check out the full list of extractable relationships and don’t worry, if you’re interested in “open” relationships, Rosette can still return that information as well, just set “discoveryMode” to “true”.

Entity Linking

We’ve fully removed our (previously deprecated) entity linking endpoint. As a reminder, entity linking is automatically included with every /entities call!

Entity Extraction

Our long text entity linker has been replaced by our fast short string entity linker. You will now see entity linking results from our short string linker by default. This removes linking support for Arabic.

Text Embeddings

We made some improvements to our algorithm for calculating text embeddings across multi-word input, so you should see more accurate results for document and sentence-level vectors.

Sentiment Analysis

In addition to English and Spanish, we’ve added document and entity-level sentiment analysis support  for Japanese language input (beta).

Expanded Language Support

The Rosette API now supports entity extraction in Vietnamese, short string social media entity linking in Chinese and Japanese, and Japanese-Chinese/Japanese-Korean/Korean-Chinese name matching and translation. We’ve also made some significant upgrades to our Japanese language support in general, which should be directly reflected  in your results!
