Cortical.io Inc. is a Vienna-based science startup that offers a novel approach to natural language processing through semantic fingerprinting, allowing for the efficient and scalable analysis of large text data. Their technology facilitates better understanding and comparison of meanings in language, overcoming the limitations of existing semantic systems. Applications include document retrieval, product recommendations, and profile matching without the need for deep expertise in NLP or linguistics.

- 2. © cortical.io inc. 2015 who we are • cortical.io inc. science startup in Vienna - Austria • result of the CEPT project (Cortical Engine for Processing Text) • advances in brain theory guided us to a fundamentally new approach for natural language processing • we are investor backed in the second round • we made semantic fingerprinting accessible, robust, scalable, intuitive and easy to use
- 3. © cortical.io inc. 2015 big (text) data • businesses, organizations and governments are threatened by the big data explosion. • a substantial part of this data consists of text. • computers ‘understand’ numbers but ignore the meaning of language
- 4. © cortical.io inc. 2015 the downsides existing semantic systems are… …hard to build (sometimes impossible) …inaccurate & fragile (in real-world use) …expensive to buy (licenses & services) …tricky to integrate (setup, tuning, training) …laborious to run (metadata management) …hard to maintain (dictionaries, ontologies)
- 5. © cortical.io inc. 2015 Semantic Fingerprinting 5 • semantic fingerprinting bridges the gap between natural language processing and knowledge management • language is represented using the same data format as found in the neocortex (mammalian brain) • the cortical.io Retina behaves like a sensorial organ for language • meaning is embodied in thousands of self-learned semantic features
- 6. © cortical.io inc. 2015 Semantic Fingerprinting 6 organ piano church liver • the cortical.io Retina converts every word into its semantic fingerprint • the fingerprints allow direct semantic comparison of the meanings between words • similar fingerprints have similar meanings

- 23. © cortical.io inc. 2015 simplicity • no prior expertise in natural language processing or linguistics are needed. • easy and intuitive definition of semantic filters or classifiers. • all types of text (words, sentences, paragraphs, chapters, books, etc…) are processed in the same way using fingerprints. • easy expansion to other languages by switching to any of the available language retinas. • zero configuration and no parameter tweaking needed cortical.io advantages
- 24. © cortical.io inc. 2015 cortical.io advantages efficiency • semantic fingerprints are small 2K byte sized binary vectors. • only binary operators are used - no floating point operations needed. • linear scalability as the engine takes advantage of a parallel computing infrastructure (multicore, cluster, virtualization) to match any performance needed. • high throughput as complex NLP operations are executed in a single step and are therefore much faster than with traditional statistical systems.
- 25. © cortical.io inc. 2015 quality • higher precision on NLP operations due to the large number of semantic features used (>16K). • automatic disambiguation of human language due to the novel approach. • full language independence, equally high quality results in all languages due to complete avoidance of any statistical language models. • no unintended bias as no human input is needed as gold standard. • automatic update as new words and concepts can be added continuously. cortical.io advantages
