Who Are We?

Semantics 21 are software and algorithm developers who specialise in providing state-of-the-art, intelligent, multimedia analytics applications for law enforcement and associated organisations.

In the pursuit of reducing the ‘Semantic gap’ (the intelligence separating humans from computers), our applications are designed towards replicating the intelligent decision making patterns of humans, whilst harnessing the power, automation, consistency and continuity of the latest computing technology.

We have three leading applications LASERp,LASERv andLASERm with many more products in development. Details of these can be seen in the ‘S21 Suite’ section of the website.

But What Is Semantics?

  • The study of the relationships between various signs and symbols and what they represent. [The American Heritage® Stedman's Medical Dictionary]

  • The meaning or understanding of image content [Image Semantics, Dictionary of Computer Vision and Image Processing, Fisher. R. B. et al, 2014]

What Are Our Aims?

When we design, develop and test the cutting-edge tools that we provide, we have very clear and crisp guidelines which help us ensure that we are working for you, the users of our tools. The market is saturated with tools which add layers of complexity, overload users with information, and put more pressure onto users, as opposed to assisting them in getting the job done. We are different. We strive to deliver:

  • Tools which are intuitive, simple and yet powerful; to assist the users.
  • Tools with the power required, without 'falling short' or 'overkill'; they distil complexities and simplify workflows.
  • Tools which allow users to concentrate on what they are reviewing, as opposed to the how.
  • Tools which save time, by harnessing the power of advanced algorithms, because ultimately time is money.
  • Tools which help identify more victims, and faster than our competitors. Fully compliant and in support of the Project VIC (including its UK CAID variant) eco-system of standardized technologies.


You may ask yourself why we do what we do?
We have a simple answer: All our products are aimed towards simplifying, streamlining, modernising and future proofing digital forensics.

In a constant 'cat and mouse' game of catch-up, law enforcement agencies are always on the back foot, reactive as opposed to proactive. Budget, time and expertise constraints understandably prevent them from being able to invest time and money into research to modernise procedures, and harness the power of computers.

We aim to tackle this issue, and make intelligent tools for you. Our applications are able to filter through thousands of images and videos, to actually 'understand' what their content is, how relevant the content is for the current investigation, and whether or not it needs further review.
