Artificial intelligence is spreading to all areas of life day by day. Artificial intelligence, with a great potential to find solutions to the fundamental problems of humanity, has also sparked off many debates such as being human, privacy, transparency, trust, etc. Respecting ethical sensitivities while developing artificial intelligence is an issue that is too important to be left solely to the initiative of the engineers and software developers who design the system. Considering its potential consequences, the ethics of artificial intelligence is clearly a serious issue that requires the initiative of social scientists, philosophers, engineering sciences, governments, and society itself. In this study, artificial intelligence ethics is analysed in terms of the sub-dimensions of the issue, namely, data ethics, algorithm ethics, and application ethics, and possible risks are discussed.
