Abstract: Method and apparatus for analyzing an online behavior of a user accessing a web server include: collecting, when a user terminal accesses a web server and forms a session, log data corresponding to a behavior performed by the user terminal in the session in real time; detecting log data corresponding to a trigger log among the log data; extracting, when the trigger log is detected, log data cumulated up to a detection time point of the trigger log from a start time point of the session and generating cumulative log data; and performing pattern analysis on the cumulative log data and generating behavior information corresponding to the behavior of the user terminal.

Abstract: A user tracking method includes collecting cookies in a log according to a user action on the Internet and collecting chain information by Internet communication as third information different from the cookie, and grouping cookies based on the chain information.

Abstract: System, methods, and apparatuses for storing data in a disk-based storage device incorporating multiple readers per recording surface to reduce recovery time from read errors using super-parity. An exemplary storage device comprises a read/write head and an associated recording surface. The read/write head has a plurality of readers configured to read a plurality of data tracks on the associated recording surface concurrently. The recording surface is segmented into a plurality of super blocks comprising a portion of each of a number of adjacent data tracks, the number of adjacent data tracks in each of the plurality of super blocks being equal to the number of the plurality of data tracks that can be read concurrently by the plurality of readers. Each super block further comprises parity information on one of the number of adjacent data tracks containing data recovery information for the super block.

Abstract: The disclosed technology provides for a method or system comprising determining size of a super block for a track zone in a storage medium based on at least one parameter of the track zone, wherein the super block includes a super parity for recovery of a failed sector within the super block.
