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.

Wallace Hall, formerly known as Science Hall, is a historic building located on the campus of Simpson College in Indianola, Iowa, United States.  The 2½-story, brick structure was designed by Wichita, Kansas architect, and Indianola native, William T. Proudfoot.  He would become partner in the prominent Des Moines architectural firm of Proudfoot & Bird.  This is the firm's earliest known extant building in Iowa.  The Romanesque Revival style is found in the round arched openings, stone trim, decorative brickwork, prominent gables centered at the front and rear elevations, and slender turrets on the corners.  The building was completed in 1888.  George Washington Carver studied art in the attic classroom while attending Simpson in 1890-1891.  A new science hall was completed in 1956, and named for Carver.  This building remained vacant for the most part, and suffered a fire a few years later.  It was eventually renovated, and on June 4, 1967 it was rededicated and at that time was renamed.  It now honors Henry A. Wallace, a geneticist and former Vice President of the United States.  It was listed on the National Register of Historic Places in 1991. Ray McSavaney (December 18, 1938 – July 2, 2014) was an American photographer of fine art based in Los Angeles, California.
