1. A method for multilingual data querying, comprising: sending, by a computer system, one or more words in an original language to a word ontology; receiving, by the computer system, sense descriptions of the one or more words from the word ontology; receiving a selection of one or more sense descriptions of the one or more words and a second language other than the original language for querying; translating, by the computer system, the one or more sense descriptions of the selection into the second language for querying, wherein the translating of the one or more sense descriptions of the selection into the second language generates one or more sense descriptions in the second language; translating, by the computer system, the one or more sense descriptions in the second language back into the original language, wherein the translating of the one or more sense descriptions in the second language back into the original language generates one or more reverse-translated sense descriptions for verification; and executing, by the computer system and in response to receiving a verification of the one or more reverse-translated sense descriptions, a query using the one or more sense descriptions in the second language.
