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.

Masataka Ida (井田正孝 , Ida Masataka ) (5 October 1912 – 6 February 2004) was a young Lieutenant Colonel in the Military Affairs Section of the Japanese Ministry of War, at the end of World War II.  He had been stationed on Formosa (Taiwan), but was ordered back to Tokyo early in 1945.  Along with Major Kenji Hatanaka and a few others, he was one of the chief conspirators in a plot to overthrow the government of Prime Minister Kantarō Suzuki; they wished to see the institution of martial law under War Minister Korechika Anami.  The plan changed, however, into a plot, engineered by Major Kenji Hatanaka, to seize the Imperial Palace and prevent the broadcast of the Emperor's surrender speech.  Lt. Col. Ida took part in this plot only briefly, trying to talk Hatanaka out of it by the end.  Not many know about his attempted 'coup', which, although it failed, came dangerously close to lengthening the war, and altering the face of modern history.

The former loaned money primarily to military industries, but also to a wide range of other ventures, including hydroelectric generators, electric power companies, shipbuilding and petroleum.
