A computer-implemented method for predicting a user navigation event, the method comprising: tracking a first text input to a text field using a computer processor, the text field functioning to direct network navigation operations of a web browser; consulting a set of probability data to determine a most likely network navigation destination using the first text input; and prerendering the most likely network navigation destination using the web browser by requesting content associated with the most likely network navigation destination before the most likely network navigation destination is selected by the user, wherein the method further comprises: determining a probability value for a given network navigation destination associated with the first text input by using the probability data; determining that the probability value exceeds a threshold value; prerendering the given network navigation destination in response to the probability value exceeding the threshold value; outputting a second text input in the text field related to navigating to the given network navigation destination; and updating the set of probability data to indicate an additional navigational event to the given network navigation destination associated with the first text input upon selection of the outputted second text input in the text field; wherein updating the set of probability data to indicate the additional navigational event to the given network navigation destination associated with the first text input includes increasing a frequency value associated with the given network navigation destination and the first text input. tracking a first text input to a text field using a computer processor, the text field functioning to direct network navigation operations of a web browser; consulting a set of probability data to determine a most likely network navigation destination using the first text input; and prerendering the most likely network navigation destination using the web browser by requesting content associated with the most likely network navigation destination before the most likely network navigation destination is selected by the user, wherein the method further comprises: determining a probability value for a given network navigation destination associated with the first text input by using the probability data; determining that the probability value exceeds a threshold value; prerendering the given network navigation destination in response to the probability value exceeding the threshold value; outputting a second text input in the text field related to navigating to the given network navigation destination; and updating the set of probability data to indicate an additional navigational event to the given network navigation destination associated with the first text input upon selection of the outputted second text input in the text field; wherein updating the set of probability data to indicate the additional navigational event to the given network navigation destination associated with the first text input includes increasing a frequency value associated with the given network navigation destination and the first text input. determining a probability value for a given network navigation destination associated with the first text input by using the probability data; determining that the probability value exceeds a threshold value; prerendering the given network navigation destination in response to the probability value exceeding the threshold value; outputting a second text input in the text field related to navigating to the given network navigation destination; and updating the set of probability data to indicate an additional navigational event to the given network navigation destination associated with the first text input upon selection of the outputted second text input in the text field; wherein updating the set of probability data to indicate the additional navigational event to the given network navigation destination associated with the first text input includes increasing a frequency value associated with the given network navigation destination and the first text input.
