  • Patent number: 11403355
    Abstract: A method including generating an index comprising (a) question-answer pairs generated based at least in part on a set of ingested source documents and (b) respective location metadata associated with each of the question-answer pairs. The respective location metadata can include a source document identifier of a first ingested source document of the set of ingested source documents and one or more location delimiters indicating a location of target text in the first ingested source document. The target text can correspond to a stored answer of a respective one of the question-answer pairs associated with the respective location metadata. The method also can include receiving a user question from a user. The user question can correspond to a question of a first question-answer pair of the question-answer pairs of the index.

  • Publication number: 20140357801
    Abstract: A nitrile rubber coupled via bisdihydropyrazole groups is produced by reacting a nitrile rubber which is based on conjugated dienes, ?,?-unsaturated nitriles and optionally further copolymerizable monomers as monomers, may have been hydrogenated and has covalently bonded tetrazole groups with a bifunctional ene compound in which the ene groups can each be reacted with the tetrazole groups to give dihydropyrazole groups.
