The Cortical.io Retina performs the following operations:
The Cortical.io Retina technology is accessed via a REST API. To extract keywords, detect language, and create semantic fingerprints, you can include the following API calls in your application:
/text/keywordsendpoint: Returns a list of keywords for inputted text
/text/detectlanguage endpoint: Can identify more than 50 languages
/text endpoint: Generates a semantic fingerprint for inputted text
To begin to integrate Cortical.io services into your application, register for a free API key.
To extract keywords from text or from a web page, follow the instructions on the screen.
Keywords are listed in the output area, and the meaning of the input is numerically encoded as a semantic fingerprint, which is graphically displayed as a square grid. Each blue dot on the grid contains part of the meaning of the text.
To view an example of keyword extraction from text or from a web page, at the bottom of the input area, select an example.
To view a larger fingerprint, above the fingerprint, click the double-arrow icon.
Every dot on a semantic fingerprint represents a collection of terms that are associated with one another. You can view some of the terms that are located at any of the blue dots on the grid by hovering over that dot. Dots that are close to one another on the grid are also close in meaning. Together, all blue dots on the grid represent the meaning of the inputted text or web page.
To export keywords in a .csv file for use in another application, at the bottom of the input area, click Export keywords. The .csv file is saved to your default download folder.
