Abstract
This paper aims at discussing engineering ethics from the perspective of the relationship between professional ethics and engineering ethics. Moreover, we will try to discuss the possibility of the application of engineering ethics to the information and knowledge sciences. Code of ethics, which plays a critical role in engineering ethics, is composed of two parts—norms common to engineering and norms specific to each field of technology. Therefore, if we want to apply engineering ethics to the information and knowledge sciences, we should take steps to specify the range of the field and clarify the norms in the field. In this paper, we will suggest norms specific to the information and knowledge sciences by conducting a case study to clarify the ethical problems in the technology of information filtering.
