Although there are several tools for automatic categorization, the main approaches are essentially three: keywords, statistical and rules-based systems.
Keyword systems require a list of terms that describe the knowledge/content. For those who are not linguistics or knowledge experts it may be not easy to immediately identify the basic categories (or knowledge domains) and all of the terms that describe their content for the success of their project.
Statistical systems sound appealing because they seem fully automatic. But this is not true. It is a classic, top-down, theoretical approach which typically results in a taxonomy that is [...]
Recent events related to the problems with HealthCare.gov seem to confirm the famous line (at least in the world of software) that “nobody ever got fired for buying IBM.”
The success of HealthCare.gov, opened to the public on October 1, depends in part on the ability to quickly resolve technical problems associated with the site. In the recent New York Times article that highlighted the multitude of problems with the site, one vendor, MarkLogic, was singled out as a possible culprit: “Some of the companies building the system opposed an early decision by the Medicare agency to use [...]

Today, while we are seeing more and more of the big players diving into the field of semantics most of them are not yet exploiting it in their core products.
Most approaches that you experience actually rely on machine learning, a wide variety of systems aimed at learning from data. These systems can be set up quickly and work well with data, but applied [...]
Consider these two scenarios:
8 a.m.: In advance of a product launch, a pharmaceutical analyst is at his desk, searching for news and information related to recent drug patents, highlighting the active ingredient, the intended application/use, as well as who owns it and the date and country in which it is filed, and any other pertinent information related to its performance in the market or other relevant innovations.
7 p.m.: At home, the same analyst is looking for a used car, something along the lines of a Volvo wagon, with air bags, maximum 150,000 miles, automatic [...]
Thanks to the expansion of the internet and the explosion of social media, the importance of semantic technology continues to grow. The semantic interpretation of content takes search beyond the border of keyword logic and into the network of relationships and connections between information and documents.
Inside the enterprise, unstructured information is made even more accessible by semantic technology, where the content of text documents, emails, social media posts and more is increasingly being recognized as a strategic asset.
We have identified 10 areas where we expect to see semantic technology making an impact in the coming year. See the [...]
