Cognition Network Technology: Taking On Cancer By Repositioning Knowledge In A Semantic Network

rsz_defThis week saw Frost & Sullivan award its 2013 Company of the Year to Definiens, a provider of image analysis solutions and data mining solutions for life science, tissue diagnostics, and clinical digital pathology. Definiens’ gaining of the title owes much to its work around tissue datafication that’s leveraging its Definiens Cognition Network Technology, which the company says mimics the human mind’s cognitive powers to reposition knowledge within a semantic network.

“What we do essentially is look at ways to be able to better diagnose cancer and develop therapies,” says Merrilyn Datta, CMO at Definiens. The company looks to extract data from tumor images, historically available as slides from biopsies, datafying the tissues involved to create digital images and then using its Cognition Network Technology to extract all the different relevant objects in that image and correlate them to patient outcomes. “That can be extremely, extremely powerful,” says Datta.

The image analysis technology was developed by Physics Nobel Laureate Gerd Binning, and includes a set of principles aimed at emulating the human mind’s cognitive powers, which are defined by the ability to intuitively aggregate pixels into ‘objects’ and understand the context and relationships between those objects rather than the computer’s normal way of just examining images pixel by pixel. These principles include:  context, which is established and utilized through the technology’s creation of a hierarchical network of pixel clusters representing nested structures within the image; navigation, for supporting efficient navigation inside the network in order to enable specific local processing and addressing of specific contexts; and evolution of the network, in which the individual stages of segmentation and classification are alternated and the structures represented within the network are created and constantly improved in a series of loops, whereby each classification can be enhanced with local context and specific expert knowledge.

Northwestern Joins VIVO Semantic Network

Elsevier reports that Northwestern University “in collaboration with Elsevier, a world-leading provider of scientific, technical and medical information products and services, today announced its participation in VIVO, a semantic network that enables the discovery of researchers across institutions. By bringing its researchers together in a single hub called Northwestern Scholars, an implementation of Elsevier’s SciVal Experts research networking tool, and connecting to VIVO through SciVal, Northwestern University facilitates collaboration and accelerates knowledge discovery within the organization and with other research institutions throughout the United States and beyond.” Read more

What is a Semantic Platform?

Bryan Bell, Expert SystemTo begin: Semantics is the study of meaning. It focuses on the relation between words and phrases and due to the relationship what they mean in context. Semantics is a game changer when it comes to the management of large volumes of structured and unstructured data. Having the ability to understand words in context using lexical or linguistic semantics will drive linked data initiatives and ultimately, as many believe, will make Web 3.0 a reality. With this in mind, possessing a “semantic platform” is the new marketing target for many software companies and they are quickly moving to describe themselves as a semantic platform in hopes of aligning themselves with the semantic snowball as it continues to gather speed.
