Abstract: A computer-implemented method for virtual agent conversation training is disclosed. The computer-implemented method includes determining a current state of a first stage of a conversation between a pair of virtual agents. The computer-implemented method further includes determining a pivot distance between the current state of the first stage of the conversation and a subsequent, second stage of the conversation. The computer-implemented method further includes responsive to determining that the pivot distance between the current state of the first stage of the conversation and the subsequent, second stage of the conversation is below a predetermined threshold, determining an angle of dislocation with respect to the pivot distance. The computer-implemented method further includes terminating the conversation based, at least in part, on determining that the angle of dislocation is above a predetermined threshold.

Abstract: An apparatus is disclosed which includes at least one processing device comprising a processor coupled to a memory. The at least one processing device, when executing program code, is configured to: extract one or more entities identified in a plurality of data artifacts based at least in part on one or more datasets, extract one or more entities identified in a plurality of code artifacts based at least in part on the one or more datasets, extract one or more entities identified in a plurality of user interface artifacts based at least in part on the one or more datasets, generate a set of dependency graphs each based at least in part on one or more relationships among the respective extracted one or more entities, and perform one or more of a lexical analysis and a semantic analysis on the set of dependency graphs to identify a data domain of the one or more datasets.

Abstract: The invention provides compounds of the formula: wherein L1 and L2 are independently selected from O and S; R1 is C3-C6 straight or branched alkyl, C3-C7cycloalkyl, C5-C7cycloalkenyl, adamantly, phenyl or saturated heterocyclyl, any of which being optionally substituted; R2 is H, methyl or ethyl; R5 is NRxCORy, NRxRy, CH2COCH3, CH2C?N, or a 5- or 6-membered heteroaryl group which is optionally substituted; X, Y and Z are independently N or CH; Rx is independently H or C1-C4alkyl; Ry is independently H, CrC4alkyl, phenyl or benzyl, either of which is optionally substituted; n is 0-3; salts, hydrates and N-oxides, wherein the optional substituents are further defined in the claims. The compounds have utility in the prophylaxis or treatment of trypanosomal diseases, such as T. cruzi (Chagas disease).
