Abstract: Disclosed are a method for extracting a feature string, a device, a network apparatus, and a storage medium. The method comprises: determining, for each candidate feature string, a transition probability for each pair of adjacent characters in the candidate feature string according to a first-order Markov transition probability matrix; detennining a transition entropy value of the candidate feature string according to the transition probability of each pair of adjacent characters and the logarithm of the transition probability; and labeling a candidate feature string having a transition entropy value greater than a pre-determined threshold as a first usable feature string, and using a valid first usable feature string as an extracted target feature string.

Abstract: A mobile terminal and a method of processing loadable contents, the method includes: presetting a mapping relationship between matching conditions and loadable contents; and loading a corresponding loadable content according to the mapping relationship when the matching condition is satisfied. The technical solution realizes corresponding loading of interface loadable content and application loadable content according to the set matching condition such as network switching, and/or terminal hardware condition change, and/or user information change and/or the like, thus simplifying the setting of the loadable content and improving the working performance of the mobile terminal.
