Lexigram v4 API Demo

Welcome to the Lexigram Demo site. Below you'll find a few interactive components that allow you to play directly with our data endpoints (no code required). To play on your own get an API key from the Get Access link in the menu. Please direct any questions or requests to support@lexigram.io.

Data Extractions

Trying to make sense of an unstructured blob of text? These are the endpoints for you. The data extraction endpoints allow you to extract medical concept mentions alongside contextual information, or highlight your text with findings in the form of HTML span tags.

Our contextualization currently includes negation and speculation, vitals, lab values, medications and their dosage, anatomy, history, allergies, and modifiers. Learn more about the importance of contextualization in medical NLP in our Lexipedia.

Extract Entities

Path: /extract/entities

The core of our data extraction API. Matches the input text against concepts in the Lexigraph to find and extract concept matches. Maintains pointers to the exact character offsets matched in the text. Identifies the types of the concept (drug, anatomy, problem, etc.) and its context (negation, speculation, ...).

Highlight Entities

Path: /highlight/entities

Returns HTML enriched versions of the input text surrounding found concepts in span tags to aid visualization of the data.
