ABOUT US

Semasphere was founded in 2010 In London, UK to develop technologies in the area of knowledge-based data analytics and to provide services for applications and products where knowledge integration can significantly enhance the value of the output. The company was created to leverage significant experience in using domain expertise to extract high value from data using specialised techniques such as data mining, information fusion and context-based analysis.

Dr. Dan Grecu is the founder and the Technology Lead of Semasphere. Over the past two decades, Dr. Grecu has accumulated a unique experience in developing and enhancing techniques for generating high-value information from data using domain, expert and context-based knowledge. The machine learning techniques he developed as part of his PhD work in the US have been part of a patent for generating methods for network intrusion detection and prevention based on application behaviour signatures. They were also part of the core technology of Okena, a network security start-up acquired by Cisco Systems. As part of the research he conducted in response to NASA flight safety challenges, he developed an advanced methodology for detecting and characterizing technical flight incidents in large volumes of flight data. He currently leads R&D work focusing on developing widely usable tools for exploration and discovery of high-value information in large data repositories using domain, expert and context knowledge.
