1. One or more non-transitory electronic memory devices including computer instructions for performing a method for processing natural language, the computer instructions being configured to perform the steps of: providing access to a clinical text, the clinical text including a plurality of groups of characters; providing access to a first database and a second database, the first database including associations between a plurality of known words and a plurality of semantic concepts, and the second database including associations between a plurality of episodic concepts and at least one of the plurality of known words and the plurality of semantic concepts, the plurality of episodic concepts being separate from the plurality of semantic concepts; identifying one or more of the plurality of groups of characters as corresponding to at least one of the plurality of known words; creating a list of the identified known words; querying the first database to obtain a set of one or more semantic concepts associated with each of the identified known words; annotating the list of identified known words with the set of semantic concepts associated with each identified known word; querying the second database to obtain a set of one or more episodic concepts associated with the set of semantic concepts; creating a semantic network having a plurality of nodes corresponding to the sets of semantic and episodic concepts and weighted links between the sets of semantic and episodic concepts; utilizing spreading activation algorithms to refine the weighted links in the semantic network; and selecting at least one of the concepts from the sets of semantic and episodic concepts based upon an associated weight for the at least one node derived from the step of utilizing spreading activation.
8. The one or more non-transitory memory devices of claim 1 , wherein the clinical text comprises at least one suicide note and the method further comprises the step of evaluating the suicide note for concepts indicative of suicidal intent.
