A graphic for understanding semantic technology

Many people grasp the idea of what semantic technology is, at least from the point of view of how semantics relates to the meaning behind words, but conveying how it works, and why, to customers, journalists, or even friends, can be a bit more complex.

All of the nuances of the expression of human language – slang, abbreviations, idiomatic expressions – make extracting the precise meaning of a given word or phrase difficult without a deep understanding of contextual meaning. This is what differentiates semantics from other technologies because it is able to mirror how people, not computers, process information.

When trying to explain how our semantic technology works, sometimes a verbal explanation is not enough – it’s not easy, after all, to put 300+ human years of development into a few words… Which is why a live, personalized demo is the best way to understand, and appreciate all of the mechanisms at work behind our technology.

Another way is through the classic graphic that we use in every presentation.  Here, we use the example of things that we use every day – emails, tweets, text documents – types of unstructured information, which are human created, and therefore subject to all of the ambiguities of language, for an example. If we follow the graphic below, we can see how Cogito processes unstructured information:

Cogito scheme

1: Unstructured information in different formats and from different sources (documents, emails, web pages, news streams, etc.) is our input text.

2: The Semantic analysis process encompasses different levels of analysis (morphological analysis, parsing, sentence analysis, semantic analysis) and our semantic network, Sensigrafo, which is a representation of knowledge – the meanings of words, the relationships between concepts – that reflects the richness of how knowledge is structured. This part of the process allows Cogito to accurately interpret the meaning of any text.

3: The output of the analysis is a conceptual map – a structured representation of the previously unstructured text.

4: The conceptual map is the starting point from which to leverage data for any number of information related challenges: semantic search, text analytics, automatic categorization, natural language processing, sentiment analysis, and more.

We invite you to contact us for a live demonstration to see first hand how Cogito could help you and your business manage information for competitive advantage.
