Task: Question Answering
Input (English): Context: The Korean Empire (Hanja: ; "Daehan Jeguk"; literally "Great Korean Empire") was proclaimed in October 1897, after the Donghak Peasant Revolution of 1894 to 1895 and Gabo Reforms that swept the country from 1894 to 1896. It lasted until the annexation of Korea by Japan in August 1910., Seoul ()  officially the Seoul Special City  is the capital and largest metropolis of the Republic of Korea (commonly known as South Korea), forming the heart of the Seoul Capital Area, which includes the surrounding Incheon metropolis and Gyeonggi province, the world's 16th largest city. It is home to over half of all South Koreans along with 678,102 international residents., The Tumen River, also called the Tuman River (called the "Duman" in South Korea), is a long river that serves as part of the boundary between China, North Korea and Russia, rising on the slopes of Mount Paektu and flowing into the East sea. The river has a drainage basin of 33,800 km (13,050 sq mi)., Japan ("Nippon" or "Nihon" ; formally "" or "Nihon-koku", means "State of Japan") is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, It is lying off the eastern coast of the Asia Mainland (east of China, Korea, Russia) and stretching from the Sea of Okhotsk in the north to the East China Sea and near Taiwan in the southwest. , Kaesong (Gaeseong) is a city in North Hwanghae Province in the southern part of North Korea, a former Directly-Governed City, and the capital of Korea during the Taebong kingdom and subsequent Goryeo dynasty. The city is near the Kaesong Industrial Region close to the border with South Korea and contains the remains of the Manwoldae palace. Called Songdo while it was the ancient capital of Goryeo, the city prospered as a trade centre that produced Korean ginseng. Kaesong now functions as the DPRK's light industry centre. It was also known by the Japanese pronunciation of its name, "Kaij", during the Japanese occupation from 1910 to 1945., East Asia is the eastern subregion of the Asian continent, which can be defined in either geographical or ethno-cultural terms. Geographically and geopolitically, it includes China, Hong Kong, and Macao; Mongolia and Taiwan; North and South Korea; and Japan; it covers about , or about 28% of the Asian continent, about twice the area of Europe., Vietnam, officially the Socialist Republic of Vietnam (SRV), is the easternmost country on the Indochina Peninsula in Southeast Asia. With an estimated 90.5 million inhabitants , it is the world's 14th-most-populous country, and the eighth-most-populous Asian country. Vietnam is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, Thailand across the Gulf of Thailand to the southwest, and the Philippines, Malaysia and Indonesia across the South China Sea to the east and southeast. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1976., The Kingdom of Joseon (literally "Great Joseon State"; also Chosn, Choson, Chosun) was a Korean kingdom founded by Yi Seonggye that lasted for approximately five centuries, from July 1392 to October 1897. It was officially renamed the Korean Empire in October 1897. It was founded following the aftermath of the overthrow of Goryeo in what is today the city of Kaesong. Early on, Korea was retitled and the capital was relocated to modern-day Seoul. The kingdom's northernmost borders were expanded to the natural boundaries at the Yalu and Tumen Rivers through the subjugation of the Jurchens. Joseon was the last dynasty of Korea and its longest-ruling Confucian dynasty., Hanja is the Korean name for Chinese characters. More specifically, it refers to those Chinese characters borrowed from Chinese and incorporated into the Korean language with Korean pronunciation. "Hanja-mal" or "hanja-eo" refers to words that can be written with hanja, and "hanmun" refers to Classical Chinese writing, although "hanja" is sometimes used loosely to encompass these other concepts. Because hanja never underwent major reform, they are almost entirely identical to traditional Chinese and "kyjitai" characters. Only a small number of hanja characters are modified or unique to Korean. By contrast, many of the Chinese characters currently in use in Japan and Mainland China have been simplified, and contain fewer strokes than the corresponding hanja characters., The Gabo Reform, also known as the Kabo Reform, describes a series of sweeping reforms suggested to the government of Korea beginning in 1894 and ending in 1896 during the reign of Gojong of Korea in response to the Donghak Peasant Revolution. Historians debate the degree of Japanese influence in this program, as well as its effect in encouraging modernization. The name Gabo (, ) comes from the name of the year 1894 in the traditional sexagenary cycle., A posthumous name is an honorary name given to royalty, nobles, and sometimes others, in East Asia after the person's death, and is used almost exclusively instead of one's personal name or other official titles during his life. The posthumous name is commonly used when naming royalty of China, Korea, Vietnam, and Japan., Goryeo, also spelled as Kory (9181392), was a Korean dynasty established in 918 by King Taejo. This kingdom later gave name to the modern exonym "Korea". It united the Later Three Kingdoms in 936 and ruled most of the Korean Peninsula until it was removed by the founder of the Joseon in 1392. Goryeo expanded Korea's borders to present-day Wonsan in the northeast (936943), the Yalu River (993) and finally almost the whole of the Korean Peninsula (1374)., The House of Yi , also called the Korean Imperial Household or Jeonju Yi clan , was the household of Joseon and the Korean Empire , consisting of the descendants of Yi Seonggye , the founder of Joseon , known by his posthumous name , Taejo ( `` highest ancestor '' ) . All his descendants are members of the Jeonju Yi clan , including the imperial family of the Korean Empire ( 1897 -- 1910 ) . After the Japan -- Korea Treaty of 1910 , in which the Empire of Japan annexed the Korean Peninsula , some members of the Yi clan were mediatised into the Imperial House of Japan and the Japanese peerage by the Japanese government until 1947 , just before the Constitution of Japan was promulgated . Since then , their status as royalty has not been acknowledged by any country ; however , they continue to attract occasional media attention in South Korea . This happened most recently with the July 2005 funeral of Yi Gu , former head of the royal household . At present , three members claim themselves as heirs to the throne . Yi Won , a first cousin and the son of the 9th son of Prince Ui , has posthumously adopted as son of Gu by the house members ' decision , thus regarded as de facto head of the house . Yi Hae - won , his aunt and second eldest daughter of Prince Ui , was declared as the empress by some of the house members at 2006 . Yi Seok , another son of Prince Ui , leads independent imperial restorationist organization and recognized as an heir ., Korea is a historical state in East Asia, since 1945 divided into two distinct sovereign states: North Korea (officially the "Democratic People's Republic of Korea") and South Korea (officially the "Republic of Korea"). Located on the Korean Peninsula, Korea is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the East Sea., Subject: house of yi, Relation: part_of, Options: (A) asia (B) august (C) chinese (D) city (E) country (F) drainage basin (G) empire (H) goryeo (I) government (J) japan (K) japanese (L) july (M) metropolis (N) name (O) ocean (P) october (Q) part (R) river (S) sea (T) series (U) state (V) the republic (W) trade
