  • Patent number: 9740683
    Abstract: A method, a disambiguation decoder and a system is provided for disambiguation in concept identification. A set of candidate concepts of a surface form in a sequence of surface forms in a plaintext is obtained. First probabilities for the candidate concepts are then determined, wherein a first probability indicates likelihood that the surface form represents the respective candidate concept. One of the candidate concepts is selected for the surface form based on the first probabilities and adjacency of the surface forms in the sequence.

  • Publication number: 20170046780
    Abstract: A method for making a decision of long step and healthy credit limit enhancement. A computer constructs a Markov decision process graph which includes nodes and edges, wherein the nodes represent respective states of one or more customer segments and the edges represent paths based on historical data. The computer applies long step actions for a respective one of the one or more customer segments, wherein the long step actions enhance more than one credit limit levels. The computer calculates gained values of the long step actions. The computer chooses an optimal long step action from the long step actions, wherein the optimal long step action has a maximum gained value.
