Ex Input:
Context_1 : A vanity label (see related topic on vanity press) is an informal name given sometimes to a record label founded as a wholly or partially owned subsidiary of another, larger and better established (at least at the time of the vanity label's founding) record label, where the subsidiary label is (at least nominally) controlled by a successful recording artist, designed to allow this artist to release music by other artists they admire. The parent label handles the production and distribution and funding of the vanity label, but the album is usually released with the vanity label brand name prominent. Usually, the artist/head of the vanity label is signed to the parent label, and this artist's own recordings will be released under the vanity label's brand name. Creating a vanity label can be an attractive idea for the parent label primarily as a "perk" to keep a successful artist on the label's roster happy and a venue to bring fellow artists to the public's attention. Context_2 : The Synthesis Tour is a concert tour by American rock band Evanescence, in support of their fourth album "Synthesis". This will be the first tour where the band includes an orchestra. The tour includes 28 concerts in different cities across North-America in 2017 and 15 concerts in Europe in 2018. Context_3 : Heartbeat Records is an independent record label based in Burlington (formerly Cambridge), Massachusetts. The label specializes in Jamaican music. Founded by reggae music enthusiasts Bill Nowlin and Duncan Brown, the label's first release was a vinyl LP reissue of Linton Kwesi Johnson's "Dread Beat an' Blood" (1981). In 1983, Chris Wilson was hired as VP of A&R and the label began their association with Studio One label founder Clement Dodd and released "Best of Studio One", a compilation of Dodd-produced music by artists including Dennis Brown, Alton Ellis, The Gladiators, Marcia Griffiths, The Heptones, Slim Smith, Sugar Minott, and Johnny Osbourne, among others. Heartbeat has released over 60 Studio One albums. The label licensed music from a number of different Jamaican producers including Lee "Scratch" Perry, Joe Gibbs, Sonia Pottinger, Clancy Eccles, Alvin Ranglin, Duke Reid, Niney the Observer, Sly & Robbie, Steely & Clevie, and Lloyd Daley. The label financed and booked the Heartbeat Culture Splash Tour, consisting of Michael Rose, Sister Carol, the Meditations, Derrick Morgan, and the S.A.N.E. band, that toured the United States in 1996. In 2000, Heartbeat Records received a Grammy Award for Burning Spear's Heartbeat album entitled "Calling Rastafari" (1999) which has since been deleted from the catalog. Heartbeat Records won Boston magazine's Best of Boston 2000 award for Best Record Label. In January 2007, Heartbeat relocated to Burlington, Massachusetts. The same year, Heartbeat launched the web site and podcast entitled the Heartbeat Reggae Podcast. Context_4 : Hysterics is the second studio album released by British post-punk band The Nightingales. It was released in 1983 through the Red Flame record label and was distributed by Pinnacle. In 2004, it was re-released by the Cherry Red record label. The album spent several weeks in the top 20 in the UK Indie Chart. Context_5 : The IBCT is an independent record label owned by Kris J. Kraus, based in Southern California and started in 2009 by Walter Adam "Dirty Walt" Kibby, II, of Fishbone, and Roderick Byron "Rodcore" Palmer of the band Year Of The Dragon along with their then manager, Kraus, an attorney, who previously was the road manager for The Incredible Lance Diamond and manager of Rick James's Original Stone City Band, among others. The label released the first full-length by YOTD, Blunt Force Karma (Produced by Darryl Swann with Kraus and Kibby as Executive Producers), and the sophomore release by Dirty Walt And The Columbus Sanatation (produced by Kibby with Kraus as Executive Producer). Subsequently, the label reissued the debut of Seattle's experimental jazz quartet Uncle Pooch, Conduct Unbecoming. The label showcased at South By Southwest in 2009, 2010, and 2011. Kibby and Palmer left the label in 2010 after YOTD's tour in support of Blunt Force Karma (to date BFK is YOTD's only full-length release and most likely will remain so as Palmer left the band in 2015), leaving Kraus as the sole owner and operator. Kraus then commissioned Uncle Pooch's bassist Shane Smith as the label's Musical Director. With Smith providing all musical content and Kraus providing lyrics, artwork, and production the two of the have teamed up to guide the label through its second phase focusing exclusively on underground and uncompromising artists who defy categorization. Two more releases by Uncle Pooch, Oneiroprenia (with production by Scott Colburn, Darryl Swann, and Kraus and graphic design by Mike Sparrow) and Sonarchy (produced by Smith and Kraus graphic design by Sparrow) in 2012. After a hiatus while Kraus pursued a career as a law professor and Smith worked on demos with various artists the label returned with Smith and Los Angeles underground icon Blackbird contributing a song to the Black Rock Coalition's 25 Year Anniversary Compilation in 2016 at Kraus' urging. Smith's band Shane Smith's Karmic Unrest released their debut "The Ambivalence Of The Scared" (produced by R. L. Heyer and Kraus and mastered by Peter A. Barker) in 2017. Uncle Pooch's final album, "The Comfort Of Violence", and two releases by Headlock are scheduled for release in late 2017. The label plans on re-issuing the debut EP by unsung pioneering black rockers Sky Church originally released in 1993 by Kraus and guitarist Mytch Meadows and remastered by Barker in 2018 for the releases 25th anniversary. Context_6 : Jarren Giovanni Benton (born October 26, 1981) is an American rapper from Decatur, Georgia. In early 2012, he signed to rapper Hopsin's independent record label Funk Volume and released a mixtape called "Freebasing with Kevin Bacon" in June 2012. A year later, on June 11, 2013 he released his debut studio album "My Grandma's Basement", which received positive critical reviews and debuted at number 152 on the "Billboard" 200. On January 4, 2016, Jarren Benton posted a prank on Instagram, saying that he dropped his current label, "Funk Volume," for a label no longer in existence entitled "No Limits." Fans and news outlets alike took the prank seriously, and spread the joke as truth on the internet because they refused to find solid evidence and verify confirmation of fact to the joke. Both Funk Volume and Jarren Benton have disproved truth to the prank in the same night. However, it has been officially confirmed the Funk Volume label has split up. After the Funk Volume split up, Jarren has created his own record label under the name Benton Enterprises, choosing to go in his own direction to get his own brand out to the public, and to release his new album Slow Motion Vol. 2. The album originally was scheduled to be released on July 15th, but Jarren posted on social media on July 3rd, 2016 "Due to technical difficulties, we will be releasing Slow Motion Vol. 2 on July 22nd." The album will be released on his new website and will be his first album release under his label Benton Enterprises, his first album release since the Funk Volume departure, and his first album released on his new website. Context_7 : Overgrown Eden is the debut album from Essex alternative metal band InMe. The album was released in the UK on 30 January 2003. The album produced four singles before and after the album's release. The singles released were "Underdose", "Firefly", "Crushed like Fruit" and "Neptune". The album was re-released in its original format on 5 June 2006. This was due to getting the rights for "Overgrown Eden" from the now defunct record label Music for Nations. Due to the demise of MFN, this was the first and last album released by InMe on this record label. Context_8 : Synthesis is the upcoming fourth studio album by American rock band Evanescence. It is set to be released on November 10, 2017, by BMG Rights Management. The album includes reworked versions of the band's previous material with an orchestral arrangement and electronica music elements, in addition to two new songs. David Campbell was responsible for the arrangement, along with Amy Lee and producer William B. Hunt. In order to promote the new material, Evanescence will embark on the Synthesis Tour, which begins on October 14, 2017, in Las Vegas and visits cities across the US and Canada until December. Context_9 : The Kill 'Em All Tour was the first major concert tour by American thrash metal band Metallica. The tour, which was sponsored by their record label, Megaforce Records, was in support of their debut album, "Kill 'Em All", released two days before the start of the tour. Metallica supported Raven, Venom and Twisted Sister while supporting acts for Metallica included Anthrax and Armored Saint. Tour setlists consisted of songs off their debut album, cover songs including Diamond Head's "Am I Evil?" and Blitzkrieg's self-titled song, and songs that would be released on "Ride the Lightning." Context_10 : Uncle B is the debut studio album released by N-Dubz. The album is dedicated to former N-Dubz manager and father of Dappy, Byron Contostavlos, who died shortly before the band were signed to their second record label All Around the World. It entered the official UK Albums Chart at number 11. On January 6, 2009, it was announced on the official All Around the World website that the album had gone platinum. Seven singles have been released from the album, with the first three being released by LRC, and the last four being released by All Around the World. The album was not released until in 2008, despite recording starting in 2006. This was due to the group changing record label from LRC to All Around the World. fact_1 : The Synthesis Tour is a concert tour by American rock band Evanescence, in support of their fourth album "Synthesis". fact_2 : It is set to be released on November 10, 2017, by BMG Rights Management.

Context_1 : The "Imprisoned Graves" are a set of graves in a small cemetery located in the Central Jail of Nicosia, where 13 EOKA fighters, during the 1955-1959 liberation struggle for the liberation of Cyprus from the United Kingdom, were interred. Nine of them were hanged by British executioner Harry Allen, three were killed in action and one died in hospital from wounds. Context_2 : Junaid Hussain (Arabic: , 1994 25 August 2015) was a British Pakistani black hat hacker and propagandist under the "nom de guerre" of Abu Hussain al-Britani who supported the Islamic State of Iraq and the Levant (ISIL). Hussain, who grew up in Birmingham in a Pakistani-origin family, was jailed in 2012 for hacking Tony Blair's accounts and posting his personal information online. Hussain left the UK around 2013 for Syria. Sporadic reports surfaced from British media in 2014 speculating that Hussein could have been the infamous British executioner Mohamed Emwazi, then only known as his tabloid nickname "Jihadi John". Context_3 : Josef Kramer (10 November 1906 13 December 1945) was the Commandant of the Bergen-Belsen concentration camp. Dubbed The Beast of Belsen by camp inmates, he was a notorious German Nazi war criminal, directly responsible for the deaths of thousands of people. He was detained by the British army after the Second World War, convicted of war crimes and hanged on the gallows in Hamelin prison by British executioner Albert Pierrepoint. Context_4 : Arthur Bartholomew English was a British man who became Canada's hangman in 1912, when he was officially offered the job. Prior to this he had been an assistant to John Radclive, a veteran of twenty years of hangings. English served in this capacity until 1935. He probably used the pseudonym of Arthur Ellis after the famous English executioner, John Ellis: there is no truth in the story that John Ellis was his uncle, as John Ellis only had one brother, James Preston who was born in 1887, and therefore would have been only 25 when Arthur Ellis started his career. It is estimated that English carried out more than 600 hangings over his career. Several of his successors adopted the same pseudonym. Context_5 : Anthony Walker (21 February 1987 30 July 2005) was a Black British student of African descent from Huyton, Merseyside, England, who was murdered with an ice axe by Michael Barton (brother of footballer Joey Barton) and his cousin Paul Taylor, in an unprovoked racially motivated attack. Walker was eighteen years old and was in his second year of A-levels. He lived with his mother Gee Walker, his father Steve Walker, his two sisters and one brother. Context_6 : Pierrepoint (titled Pierrepoint: The Last Hangman for North American release), is a 2005 British film directed by Adrian Shergold about the life of British executioner Albert Pierrepoint. Context_7 : Harry Bernard Allen (5 November 1911 14 August 1992) was one of Britain's last official executioners, officiating between 1941 and 1964. He was chief executioner at 41 executions and acted as assistant executioner at 53 others, at various prisons in England, Scotland, Northern Ireland, the Channel Islands and Cyprus. He acted as assistant executioner for 14 years, mostly to Albert Pierrepoint from 1941 to 1955. Context_8 : Thomas William Pierrepoint (1870 11 February 1954) was a British executioner from 1906 until 1946. He was the brother of Henry and uncle of Albert. Context_9 : John Ellis (4 October 1874 20 September 1932) was a British executioner for 23 years, from 1901 to 1924. His other occupations were as a Rochdale hairdresser and newsagent. Context_10 : Henry Albert Pierrepoint (1878 14 December 1922) was a British executioner from 1901 until 1910. He was the father of Albert and brother of Thomas. fact_1 : He probably used the pseudonym of Arthur Ellis after the famous English executioner, John Ellis: there is no truth in the story that John Ellis was his uncle, as John Ellis only had one brother, James Preston who was born in 1887, and therefore would have been only 25 when Arthur Ellis started his career. fact_2 : John Ellis (4 October 1874 20 September 1932) was a British executioner for 23 years, from 1901 to 1924. Question: Who had only one brother and was a british executioner for 23 years?

Context_1 : Mykhailo Pylypovych Kravchuk, also Krawtchouk (Ukrainian: ) (September 27, 1892 March 9, 1942), was a Soviet Ukrainian mathematician who, despite his early death, was the author of around 180 articles on mathematics. Context_2 : Fortune's algorithm is a sweep line algorithm for generating a Voronoi diagram from a set of points in a plane using O("n"log"n") time and O("n") space. It was originally published by Steven Fortune in 1986 in his paper "A sweepline algorithm for Voronoi diagrams." Context_3 : Georgy Feodosevich Voronoy (Ukrainian: ; Russian: ; 28 April 1868 20 November 1908) was a Russian and Ukrainian mathematician. Among other things, he defined the Voronoi diagram. Context_4 : In computational geometry, a power diagram is a partition of the Euclidean plane into polygonal cells defined from a set of circles, where the cell for a given circle "C" consists of all the points for which the power distance to "C" is smaller than the power distance to the other circles. It is a form of generalized Voronoi diagram, and coincides with the Voronoi diagram of the circle centers in the case that all the circles have equal radii. Context_5 : In mathematics, a Voronoi formula is an equality involving Fourier coefficients of automorphic forms, with the coefficients twisted by additive characters on either side. It can be regarded as a Poisson summation formula for non-abelian groups. The Voronoi (summation) formula for GL(2) has long been a standard tool for studying analytic properties of automorphic forms and their "L"-functions. There have been numerous results coming out the Voronoi formula onGL(2). The concept is named after Georgy Voronoy. Context_6 : In mathematics, a weighted Voronoi diagram in "n" dimensions is a special case of a Voronoi diagram. The Voronoi cells in a weighted Voronoi diagram are defined in terms of a distance function. The distance function may specify the usual Euclidean distance, or may be some other, special distance function. Usually, the distance function is a function of the generator points' weights. Context_7 : Ivan Ivanovich Ivanov (Russian: ; 11 August 1862 17 December 1939) was a Russian-Soviet mathematician who worked in the field of number theory. Together with Georgy Voronoy he continued Pafnuty Chebyshev's work on the subject. Context_8 : In geometry, the positive and negative Voronoi poles of a cell in a Voronoi diagram are certain vertices of the diagram. Context_9 : In mathematics, a Voronoi diagram is a partitioning of a plane into regions based on distance to points in a specific subset of the plane. That set of points (called seeds, sites, or generators) is specified beforehand, and for each seed there is a corresponding region consisting of all points closer to that seed than to any other. These regions are called Voronoi cells. The Voronoi diagram of a set of points is dual to its Delaunay triangulation. Context_10 : In geometry, a centroidal Voronoi tessellation (CVT) is a special type of Voronoi tessellation or Voronoi diagram. A Voronoi tessellation is called centroidal when the generating point of each Voronoi cell is also its mean (center of mass). It can be viewed as an optimal partition corresponding to an optimal distribution of generators. A number of algorithms can be used to generate centroidal Voronoi tessellations, including Lloyd's algorithm for K-means clustering. fact_1 : Mykhailo Pylypovych Kravchuk, also Krawtchouk (Ukrainian: ) (September 27, 1892 March 9, 1942), was a Soviet Ukrainian mathematician who, despite his early death, was the author of around 180 articles on mathematics. fact_2 : Georgy Feodosevich Voronoy (Ukrainian: ; Russian: ; 28 April 1868 20 November 1908) was a Russian and Ukrainian mathematician. fact_3 : Among other things, he defined the Voronoi diagram.
