Entity Extraction

Automatically find names of people, places, organizations and more across many languages

entity extraction


Things not strings

Entities are the key actors in your text data: the organizations, people, locations, products, dates and more that are mentioned in your content. Using a synthesis of established text analysis best practices and machine learning statistical modeling, Rosette uncovers these entities, delivering structure, clarity, and insight to your data.

Real world applications

Entity extraction is the foundation for applications in eDiscovery, social media analysis, financial compliance and government intelligence. Rosette allows you to:

  • Resolve a person’s identity for government security and fraud detection
  • Track customer sentiment around products and companies
  • Analyze research for patent law, legal discovery, and compliance
  • Exploit valuable information from open source intelligence
  • Provide targeted search for content publishers and recommendation engine

Customizable to your unique needs

Rosette is unique among entity recognition software in its adaptability. In addition to supervised training, our on-premise field training kits enable you to run unsupervised training on your own data to create personalized entity extraction models for your use case.

This can mean training Rosette on a specific type of content, such as news articles, blogs, restaurant reviews, financial documents, medical records, legal contracts, patent filings, or short strings of text like tweets. It can also involve creating new entity types beyond our pre-built list, such as disease and drug names for a medical extractor or job titles and skills for resume evaluation.

Product Highlights

  • 20 supported languages
  • 18 entity types detected
  • Intuitive cloud API
  • Customizable SDK
  • Fast and scalable
  • Industrial-strength support
  • Constantly stress-tested and improved

How It Works

A powerful hybrid solution

Rosette entity extraction is a hybrid solution: combining established natural language processing best practices such as advanced statistical modeling complemented by regular pattern matching and gazetteers. This combination gives Rosette the flexibility to extract entities missed by more simplistic solutions, improving accuracy and recall.

Statistical modeling

While regular expressions and lists are important aspects of entity extraction, Rosette’s machine learning and advanced linguistic processing functionality sets it apart. With statistical modeling, our users avoid four major problems inherent to simplistic extraction solutions:

  • Labor required to create an comprehensive list of all necessary entity types
  • Unknown entities will be missed by even the most exhaustive list
  • Lack of context consideration means that place names (Newton, MA) may be confused with people names (Isaac Newton)
  • Failing to extract misspelled list items

To meet these concerns, Rosette entity extraction starts with a statistical model that is trained on millions of news and blog articles. As a result, it understands the context of both common entities you expect to find like people, organizations, products, and locations, as well as new entities you were unaware of.

Pattern matching

Rules expressed as regular expressions find entities which follow a pattern, such as dates, times, and email addresses. Many standard string patterns are pre-built into Rosette, and on-premise customers can easily customize their extraction workflow by editing or adding rules based on their specific needs.

Gazetteers and entity lists

Rosette extracts 18 common entities types including people, organizations, products, and locations (full list above). Unlike a home-brew or academic extractor, Rosette’s gazetteers are regularly updated and stress-tested for enterprise level speed and performance.

Custom entity lists or gazetteers, available to on-premise customers, can be added when users know specific words or phrases that they expect to discover in their data. For example, a clothing manufacturer may add a list of basic colors they’d like to extract from tweets.
