15. A system comprising: a computing device including a processing unit and a memory, the processing unit implementing a spoken language system and a dialogue state belief tracking system, the spoken language system is operable to: receive a spoken language input, identify tags within the spoken language input, and communicate with the dialogue state belief tracking system; and wherein the dialogue state belief tracking system is operable to: communicate with the spoken language system, search a knowledge base framework based on the tags identified by the spoken language system; identify entities, attributes, and relationships within the knowledge base framework that match at least some of the tags; create a state graph based on a portion of the knowledge base framework that includes any matched entities, matched attributes, and identified relationships, wherein the state graph is formed by transforming the portion into a probabilistic model graph and by adding evidence nodes to the probabilistic model graph based on the tags, and wherein the state graph includes a confidence indicator for each node of the state graph; rank nodes of the state graph; determine at least one goal based on the rank of the nodes of the state graph; and send instructions to perform an action based on the at least one goal.

The system of claim 15 , wherein the dialogue state belief tracking system is further operable to: receive user data, search the knowledge base framework based on the user data; identify at least one additional entity, additional attribute, and additional relationship that match the user data; identify a second portion of the knowledge base framework that includes any matched additional entity, matched additional attribute, and matched additional relationship to the user data; and update the state graph based on the second portion of the knowledge base framework, wherein the second portion is clamped on to the state graph by aligning common nodes.
