Semantic Signatures®

A Semantic Signature® is a representation of ALL concepts covered in a block of text. Each block of text contains semantic dimensions ("concepts") with associated weights. The dimensions capture the strength of each concept in the text.

Semantic Signatures® provide a weighted representation of the concepts contained in a piece of text. The weight of each concept represents the strength of that concept in the text. The Semantic Signatures® for two pieces of text that both address the same subject will share many common concepts with high weights. Our technology can therefore recognize that these two pieces of text are related even though they share no common keywords.

This is an example of the semantic concepts with their respective weights for the Magnetic Field article in Wikipedia. A sample of the concepts and weights of that page are below:

Science/Physics/Electromagnetism (0.59533894)

Shopping/Health/Alternative/Magnetic_Therapy (0.3567098)

Business/Industrial_Goods_and_Services/Industrial_Supply/Magnets (0.3112189)

These dimensions and their associated weights can also be used to easily organize text. Other semantic technologies cannot do this unless they first understand the text. You can see the power of Semantic Signatures® using the Wikipedia Extension demo we have provided.

Semantic Signatures® can be constructed for a wide range of texts including words, phrases, word-lists (e.g. metadata), short text (such as text advertisements), web pages, or full text documents.

The Benefits of Using Semantic Signatures®

  • Automatically generates semantic dictionaries from categorized content.
  • Overcomes the failure of keyword matching and classification.
  • Understands unstructured content with no human intervention.
  • Highlights the topic strengths and subtle interactions of meaning within each document that make the document unique.
  • Bypasses the computational complexity of deep natural language understanding.
