Compare Text

To compare text or web pages, follow the instructions on the input screen below. The meaning of the two texts is numerically encoded as two semantic fingerprints, which are graphically displayed as two square grids. Each blue dot on a grid contains part of the meaning of the text. A third grid, between the other two, indicates with orange dots where the left and right grids overlap. The overlap in meaning between the two texts is quantified as a percentage.

Exploring semantic fingerprints +

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.

How it works +

The Cortical.io Retina performs the following operations:

  1. Parses the input text.
  2. Detects the input language of each of the two pieces of text if the text is at least 10 words and at least 40 characters.
  3. Numerically encodes the meaning of the two pieces of text as two semantic fingerprints.
  4. Displays the semantic fingerprint as square grids, where each blue dot on a grid contains part of the meaning of the text; a third grid, between the other two, indicates with orange dots where the left and right grids overlap.
  5. Quantifies the overlap in meaning between the two pieces of text as a percentage, based on the number of overlapping points between the items to compare.
