Question: What has the recent work with stylometry revealead about some of William shakespeare's collaborations?
Context: Stylometry is the application of the study of linguistic style, usually to written language, but it has successfully been applied to music and to fine-art paintings as well. Tom Corby (born 1966) and Gavin Baily (1971) are two London based artists who work collaboratively using public domain data, climate models, satellite imagery and the Internet.  Recent work has focused on climate change and its relationship to technology and has involved collaborations with scientists working at the British Antarctic Survey. Like most playwrights of his period, William Shakespeare did not always write alone.  A number of his surviving plays are collaborative, or were revised by others after their original composition, although the exact number is open to debate.  Some of the following attributions, such as "The Two Noble Kinsmen", have well-attested contemporary documentation; others, such as "Titus Andronicus", are dependent on linguistic analysis by modern scholars; recent work on computer analysis of textual style (word use, word and phrase patterns) has given reason to believe that parts of some of the plays ascribed to Shakespeare are actually by other writers. Mnemosyne Productions was established in Norway 2003 by founders Heidi S. Tveitan/Starofash and Vegard Tveitan/Ihsahn as an extension to their work in the music industry.  This label is mainly an outlet for their own musical collaborations.  The founders have more than 10 years of experience as recording artists (Emperor, Ihsahn, Peccatum, Starofash and TSS), and have recorded and produced most of their recent work at their creative playground; SYMPHONIQUE STUDIO.  At present, they are also working with selected tasks in film and web scoring. The Cobbe portrait is an early Jacobean panel painting of a gentleman which has been argued to be a life portrait of William Shakespeare.  It is displayed at Hatchlands Park in Surrey, a National Trust property, and the portrait is so-called because of its ownership by Charles Cobbe, Church of Ireland (Anglican) Archbishop of Dublin (1686–1765).  There are numerous early copies of the painting, most of which were once identified as Shakespeare.  The Cobbe original was only identified in the collection of the Anglo-Irish Cobbe family in 2006, and had until then been completely unknown to the world.  Evidence uncovered by researchers at the Shakespeare Birthplace Trust led to the claim, presented in March 2009, that the portrait is of William Shakespeare and painted from life.  Many scholars dismiss this theory and have provided evidence to identify the portrait as one of Sir Thomas Overbury The portrait has been the centrepiece of two exhibitions dedicated to it: "Shakespeare Found: a Life Portrait" at the Shakespeare Birthplace Trust, Stratford-upon-Avon, from April–October 2009 and "The Changing Face of William Shakespeare" at the Morgan Library and Museum, New York, from February–May 2011.  An illustrated catalogue provides details of the painting and its provenance.

The Notre Dame Shakespeare Festival is a part of the University of Notre Dame's Shakespeare initiative entitled "Shakespeare at Notre Dame", a program that recognizes the centrality of the study of Shakespeare in humanistic pedagogy at the University.  Its fifteenth season (summer of 2014) was known as the 15/150, also celebrating the 450th birthday of William Shakespeare, and the 150th anniversary of the first full production of Shakespeare at the university in 1864 (Records indicate the first performance of Shakespeare at the University of Notre Dame took place in 1847, a collection of scenes also from "Henry IV)."

Tony Pinkney (born 1956) is Senior Lecturer in the Department of English, Lancaster University, England.  He played an active role in Oxford English Limited (OEL), a leftwing group pressing for progressive reforms in the Oxford University English Faculty between 1982 and 1992, and edited its journal, .  Fred Inglis has asserted in his biography of Raymond Williams that ‘Tony Pinkney was the moving spirit of OEL’.  Pinkney’s work on Raymond Williams challenged the notion of Williams as a doggedly realist writer and argued instead for his openness to certain currents in modernism and postmodernism.  Pinkney’s most recent work has focused on William Morris and utopianism and he now runs a well-known blog on this topic, 'William Morris Unbound'.  In August 2011 he launched the Kelmsgarth Press  with Makiko Minow, and he is now working on "News from Nowhere Two", a sequel to Morris's utopia.
