Context paragraphs:
Folk music of England: The folk music of England is traditionally based music, which has existed since the later medieval period.  It is often contrasted with courtly, classical and later commercial music.  Folk music has been preserved and transmitted orally, through print and later through recordings.  The term is used to refer to English traditional music and music composed, or delivered, in a traditional style.  English folk music has produced or contributed to several important musical genres, including sea shanties, jigs, hornpipes and dance music, such as that used for Morris dancing.  It can be seen as having distinct regional and local variations in content and style, particularly in areas more removed from the cultural and political centres of the English state, as in Northumbria, or the West Country.  Cultural interchange and processes of migration mean that English folk music, although in many ways distinctive, has particularly interacted with the music of Scotland.  It has also interacted with other musical traditions, particularly classical and rock music, influencing musical styles and producing musical fusions, such as British folk rock, folk punk and folk metal.  There remains a flourishing sub-culture of English folk music, which continues to influence other genres and occasionally to gain mainstream attention.

The Critics Group: The Critics Group, also known as The London Critics Group, was a group of people who met to explore 'how best to apply the techniques of folk-music and drama to the folk revival' under the direction of Ewan MacColl and Peggy Seeger, with some participation from Bert Lloyd and Charles Parker.  Running for eight years from the mid-1960s to the early 1970s, it was not a conventional musical group or band as it had no permanent line-up.  Members would perform with each other on an ad-hoc basis as situations demanded.

Open information extraction: In natural language processing, open information extraction (OIE) is the task of generating a structured, machine-readable representation of the information in text, usually in the form of triples or n-ary propositions.  A proposition can be understood as truth-bearer, a textual expression of a potential fact (e.g., "Dante wrote the Divine Comedy"), represented in an amenable structure for computers [e.g., ("Dante", "wrote", "Divine Comedy")].  An OIE extraction normally consists of a relation and a set of arguments.  For instance, ("Dante", "passed away in" "Ravenna") is a proposition formed by the relation "passed away in" and the arguments "Dante" and "Ravenna".  The first argument is usually referred as the subject while the second is considered to be the object.

Cruel River: Cruel River is the second solo studio album by English folk singer-songwriter Steve Knightley.  Knightley had spent 2006 with Show of Hands, his duo with Phil Beer, recording, releasing and promoting their twelfth album together, "Witness", which saw the duo explore a worldbeat sound that departed from their usual English folk sound.  The album was a success with critics and most fans, although some were perplexed by its direction.  During a break in promoting that album with touring in early 2007, Knightley decided to record his first solo album since 1999.  Hiring regular Show of Hands collaborator Mark Tucker to co-produce the album with himself, Knightley recorded the album in Presshouse Studios, Colyton in February 2007.  The album explores a stripped-back, minimal English folk sound, similar to that of early Show of Hands.  Lyrically, the album tackles dark subject matter.

Shirley Collins: Shirley Elizabeth Collins MBE (born 5 July 1935) is an English folk singer who was a significant contributor to the English Folk Revival of the 1960s and 1970s.  She often performed and recorded with her sister Dolly, whose accompaniment on piano and portative organ created unique settings for her sister's plain, austere singing style.

Harry Boardman: Harry Boardman (1930–1987) was an English folk singer who was born in Failsworth, Lancashire.  He sang both unaccompanied and accompanying himself on the Anglo concertina or banjo.  "Boardman has specialised in the lore, songs and dialect poems of his native Lancashire.  A fine singer, his recorded and printed work has done much to preserve the otherwise ignored aspects of his local tradition." —Fred Woods.  He was active as a folk singer and collector of Lancashire folklore from the late 1950s with some collaboration from his wife Lesley.  In 1991 the Harry Boardman Memorial Trust was established to increase public awareness of traditional music and related arts, including the folk music of the British Isles and local traditions of North West England.  Harry appeared regularly, together with Dave Hillier at the Pack Horse Hotel in Bridge Street, Manchester during the early 1960s.

Ewan MacColl: James Henry Miller (25 January 1915 – 22 October 1989), better known by his stage name Ewan MacColl, was an English folk singer, songwriter, communist, labour activist, actor, poet, playwright and record producer.

Patti Reid: Patti Reid is an English folk singer from Penrith, Cumbria, England.  She released an eponymous album on Fellside Records in 1987 and has appeared on several compilation albums featuring English folk singers.  She released another album, "Pink Sand" in 2002.

Anne Briggs: Anne Patricia Briggs (born 29 September 1944) is an English folk singer.  Although she travelled widely in the 1960s and early 1970s, appearing at folk clubs and venues in England and Ireland, she never aspired to commercial success or to achieve widespread public acknowledgment of her music.  However, she was an influential figure in the English folk music revival, being a source of songs and musical inspiration for others such as A. L. Lloyd, Bert Jansch, Jimmy Page, The Watersons, June Tabor, Sandy Denny, Richard Thompson and Maddy Prior.

Dave Burland: Dave Burland (born 12 July 1941, Barnsley, West Riding of Yorkshire, England) is an English folk singer and guitarist.  A former policeman, he has been performing in English folk clubs since 1968 and has been described by "The Guardian" as having a "uniquely relaxed singing style".
