A method for detecting abnormality adapted to detect abnormal operations of an operating system is provided. The method includes: calculating a safe range of usage of the operating system during one or more time periods according to a historical data stream; calculating abnormal ratios corresponding to the one or more time periods according to a current data stream and the safe range of usage; selecting one or more abnormal time periods from the one or more time periods according to a threshold and the abnormal ratios; calculating an abnormal indicator for each of the one or more abnormal time periods according to the historical data stream and the current data stream; and ranking the one or more abnormal time periods according to the abnormal indicator(s).

The disclosure provides a method for evaluating domain name and a server using the same method. The method includes: retrieving a raw domain name and dividing the raw domain name into a plurality of parts; retrieving a specific part of the parts, wherein the specific part include characters; encoding the characters into encoded data; padding the encoded data to a specific length; projecting the encoded data being padded as embedded vectors; sequentially inputting the embedded vectors to a plurality cells of a long short term memory model to generate a result vector; and converting the result vector to a prediction probability via a fully-connected layer and a specific function.
