15. A non-transitory computer-readable storage medium storing one or more instructions which, when executed by one or more processors, cause the one or more processors to perform steps of: generating a network model that comprises a plurality of events; wherein each event comprises a plurality of sub-events, and each sub-event corresponds to a state from a plurality of states; receiving a plurality of event-and-time-specific texts that are contextually related to a particular event; processing the plurality of event-and-time-specific texts by applying the network model to the plurality of event-and-time-specific texts to identify, within the plurality of event-and-time specific texts, a particular set of texts that belong to a particular state, of the plurality of states, of a particular sub-event; and identifying, within the particular set of texts, one or more texts that are representative of a plurality of texts in the particular set of texts that belong to the particular state and that describe information related to the particular sub-event.

The non-transitory computer-readable storage medium of claim 15 , storing additional instructions which, when executed by the one or more processors, cause the one or more processors to perform steps of: initializing one or more elements of the network model; identifying a plurality of state-and-event-specific words for the particular event in contents of the plurality of event-and-time-specific texts; and generating a modified network model based on the plurality of state-and-event-specific words and the plurality of event-and-time-specific texts.
