in Information Sciences spacetime may also have semantics, or ‘’qualitative’’ functional aspects that also need to be included in descriptions of phenomena. Graph theoretical ideas Another recurring theme of Burgess's work has been graph theory. Working with search engine researchers Geoffrey Canright and Knut Engø Monsen, Burgess developed a page ranking algorithm similar to PageRank eigenvalue sink remedies in directed graphs. This work also met with resistance from the American journal establishment, and was delayed before final publication. With PhD Student Kyrre Begnum, he explored the related technique of Principal Component Analysis for analysing correlations in the machine-learned anomalies described above. Graphs as a model of security made another connection with physics, through the idea of percolation, or path criticality. Knowledge management Since 2007, Burgess has turned his attention to the matter of knowledge representations and knowledge management, often using Promise Theory as an agency model. Music and media Burgess is an accomplished guitarist, and a composer of various styles of music from orchestral to jazz, rock and pop, which he has published amateur music freely and released a number of albums on streaming platforms. He is also an amateur oil painter and occasional digital artist. During the 2020 pandemic, Burgess produced a “zero budget” series of three documentary films called Bigger, Faster, Smarter in which he interviewed a number of industry luminaries about the nature of processes in space and time, networks, and the future of technology. The series was written, filmed, narrated and edited entirely by Burgess. He also composed and performed the music for the series.
