Translog-II is a program to record and study human reading and writing processes on a computer. In our research, it is an instrument to acquire objective, digital data of human translation processes. As their predecessors, Translog 2000 and Translog 2006, also Translog-II consists of two main components: Translog-II Supervisor is used to create a project file and to replay recorded sessions. Translog-II User is used to run a text production experiments (a user reads, writes or translates a text). Translog-II produces a log files which contains user activity data of the reading, writing and translation processes, and which can be evaluated by external tools (see TPR-DB).
