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.
Warrant Officer Kenji Yanagiya (柳谷 謙治 , Yanagiya Kenji , March 1919 – February 29, 2008) was a member of the Imperial Japanese Navy's Zero fighter aces who fought the Battle of Solomon Islands in October 1942 – June 1943.
 He is best known as the only escort fighter pilot of the Yamamoto mission to survive the war.
Major Kenji Hatanaka (畑中 健二 , Hatanaka Kenji ) (28 March 1912 – 15 August 1945) was a Japanese military officer and one of the chief conspirators in the Kyūjō incident, a plot to seize the Imperial Palace and to prevent the broadcast of Emperor Hirohito's surrender speech to mark the end of World War II.
Lt. Col. 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.
Hirohito (裕仁 , April 29, 1901 – January 7, 1989) was the 124th Emperor of Japan according to the traditional order of succession, reigning from December 25, 1926, until his death.
 He was succeeded by his eldest son, Akihito.
 In Japan, he is now referred to primarily by his posthumous name, Emperor Shōwa (昭和天皇 , Shōwa-tennō ) .
 The word "Shōwa" is the name of the era that corresponded with the Emperor's reign, and was made the Emperor's own name upon his death.
 The name Hirohito means "abundant benevolence".
Lt. Col. Masahiko Takeshita (竹下正彦 , Takeshita Masahiko ) was the head of the domestic affairs section of the Military Affairs Bureau of the Imperial Japanese Army during World War II.
 In August 1945, he helped plan a "coup" along with Major Kenji Hatanaka and a handful of others , with the intent of preventing the Emperor's announcement of Japan's surrender from being broadcast.
Lieutenant General Takeshi Mori (森 赳 , Mori Takeshi , 25 April 1894 – 15 August 1945) commanded the Japanese Empire's First Imperial Guards Division at the very end of World War II.
 He was killed by Major Kenji Hatanaka during the Kyūjō Incident.
Japanese invasion money, officially known as Southern Development Bank Notes (Japanese: 大東亜戦争軍票 "Dai Tō-A Sensō gunpyō", "Greater East Asia War military scrip"), was currency issued by the Japanese Military Authority, as a replacement for local currency after the conquest of colonies and other states in World War II.
 In February 1942 in Japan, laws were passed establishing the Wartime Finance Bank and the Southern Development Bank.
 Both institutions issued bonds to raise funds.
 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.
 The latter provided financial services in areas occupied by the Japanese military, and Southern Development Bank notes were in fact used as de facto military scrip.
 In December 1942, the outstanding balance of Southern Development Bank notes stood at more than 470 million; in March 1945, more than 13 billion.
The Jewel Voice Broadcast (玉音放送 , "Gyokuon-hōsō" ) was the radio broadcast in which Japanese Emperor Hirohito (Emperor Shōwa 昭和天皇 "Shōwa-tennō") read out the Imperial Rescript on the Termination of the War (大東亜戦争終結ノ詔書 , Daitōa-sensō-shūketsu-no-shōsho ) , announcing to the Japanese people that the Japanese Government had accepted the Potsdam Declaration demanding the unconditional surrender of the Japanese military at the end of World War II.
 This speech was broadcast at noon Japan Standard Time on August 15, 1945, after the Battle of Okinawa, the atomic bombings of Hiroshima and Nagasaki, and the Soviet invasion of Manchuria.
Comfort bag (慰問袋, "imon-bukuro") was a gift packet prepared by civilians to be sent to Imperial Japanese Military soldiers for the purpose of encouraging them.
 The bag contains comfort articles (慰問品, "imon-hin") not issued by the Japanese Military, such as toiletries, dried fruits, canned foods, and letters of encouragement.
 Bags were prepared by schoolgirls or local patriotic women's societies.
 These activities were also made in Korea, which was then under Japanese rule, to encourage Korean soldiers in the Imperial Japanese Military.
