Quertle is a biomedical and life science big data analytics company specializing in knowledge discovery and literature searching.

Company technology

Quertle has developed a suite of analytic technologies to support knowledge discovery in text information.[citation needed] The company has combined multiple artificial intelligence methods with quantum logic, computational linguistics, and statistics into a unique literature discovery solution. This combined approach includes a set of methods for identifying and understanding specific terms.[1] The method enables case-sensitive searching and word sense disambiguation of polysemic terms.

The company is also using artificial intelligence for automated identification of concepts within documents that are specifically related to why the documents match selection criteria.

Quertle also applies predictive visual analytics based on the text of the result documents, which enable understanding and exploration.

Company products

Quertle’s flagship product is its biomedical and life science search and discovery engine, Qinsight,[2] which applies the Quantum Logic Linguistics approach in combination a knowledge extraction-specific ontology (as compared to typical classification ontologies). Qinsight is an outgrowth of the company’s prior and Quetzal web sites,[3] which served as development and training test sites.

Quertle also partners with other companies to embed its technologies in other websites and products.[citation needed]
