question: What was the man that preceded Frederick IV of Hohenstaufen also known as in another language?
answer: Kaiser Rotbart
context: Title: Frederick I, Holy Roman Emperor
  Passage: Frederick I (German: "Friedrich I" , Italian: "Federico I" ; 1122 – 10 June 1190), also known as Frederick Barbarossa (Italian: "Federico Barbarossa" ), was the Holy Roman Emperor from 1155 until his death.  He was elected King of Germany at Frankfurt on 4 March 1152 and crowned in Aachen on 9 March 1152.  He became King of Italy in 1155 and was crowned Roman Emperor by Pope Adrian IV on 18 June 1155.  Two years later, the term "sacrum " ("holy") first appeared in a document in connection with his Empire.  He was later formally crowned King of Burgundy, at Arles on 30 June 1178.  He was named "Barbarossa " by the northern Italian cities which he attempted to rule: Barbarossa means "red beard" in Italian; in German, he was known as "Kaiser Rotbart ", which has the same meaning.

  Title: Round-trip translation
  Passage: Round-trip translation (RTT), also known as back-and-forth translation, recursive translation and bi-directional translation, is the process of translating a word, phrase or text into another language (forward translation), then translating the result back into the original language (back translation), using machine translation (MT) software.  It is often used by laypeople to evaluate a machine translation system, or to test whether a text is suitable for MT when they are unfamiliar with the target language.  Because the resulting text can often differ substantially from the original, RTT can also be a source of entertainment.
  Title: Language transfer
  Passage: Language transfer (also known as L1 interference, linguistic interference, and crosslinguistic influence) refers to speakers or writers applying knowledge from one language to another language.  It is the transfer of linguistic features between languages in the speech repertoire of a bilingual or multilingual individual, whether from first to second, second to first or many other relationships.  It is most commonly discussed in the context of English language learning and teaching, but it can occur in any situation when someone does not have a native-level command of a language, as when translating into a second language.
  Title: Fill-In (puzzle)
  Passage: Fill-Ins, also known as Fill-It-Ins or Word Fills, are a variation of the common crossword puzzle in which words, rather than clues, are given.  Fill-Ins are common in puzzle magazines along with word searches, cryptograms, and other logic puzzles.  Some consider Fill-Ins to be an easier version of the crossword.  Since the Fill-In requires no outside knowledge of specific subjects, one can solve the puzzle in another language.
