After discussing the distinction between artifacts and natural entities, and the distinction between artifacts and technology, the conditions of the traditional account of moral agency are identified. While computer system behavior meets four of the five conditions, it does not and cannot meet a key condition. Computer systems do not have mental states, and even if they could be construed as having mental states, they do not have intendings to act, which arise from an agent’s freedom. On the other hand, computer systems have intentionality, and because of this, they should not be dismissed from the realm of morality in the same way that natural objects are dismissed. Natural objects behave from necessity; computer systems and other artifacts behave from necessity after they are created and deployed, but, unlike natural objects, they are intentionally created and deployed. Failure to recognize the intentionality of computer systems and their connection to human intentionality and action hides the moral character of computer systems. Computer systems are components in human moral action. When humans act with artifacts, their actions are constituted by the intentionality and efficacy of the artifact which, in turn, has been constituted by the intentionality and efficacy of the artifact designer. All three components – artifact designer, artifact, and artifact user – are at work when there is an action and all three should be the focus of moral evaluation. 相似文献

文章借用鲍尔格曼的＂焦点物＂理论的视角,对新疆坎儿井在现代文化背景下角色的转变进行了分析,论证了新疆坎儿井的地位由＂焦点物＂到被＂等价设备＂所替代的过程,以及在这一过程中由于＂手段＂和＂目的＂分裂所造成的一系列环境、心理和社会问题。为了弥合这种裂痕,文章就新疆坎儿井的案例提出拯救和保护现有坎儿井的措施之一构建坎儿井＂焦点实践＂,使人们在现代化背景下能够再遇＂焦点物＂,回归生活的深刻性和完整性的建议。 相似文献

As an information medium, video offers many possible retrieval and browsing modalities, far more than text, image or audio. Some of these, like searching the text of the spoken dialogue, are well developed, others like keyframe browsing tools are in their infancy, and others not yet technically achievable. For those modalities for browsing and retrieval which we cannot yet achieve we can only speculate as to how useful they will actually be, but we do not know for sure. In our work we have created a system to support multiple modalities for video browsing and retrieval including text search through the spoken dialogue, image matching against shot keyframes and object matching against segmented video objects. For the last of these, automatic segmentation and tracking of video objects is a computationally demanding problem which is not yet solved for generic natural video material, and when it is then it is expected to open up possibilities for user interaction with objects in video, including searching and browsing. In this paper we achieve object segmentation by working in a closed domain of animated cartoons. We describe an interactive user experiment on a medium-sized corpus of video where we were able to measure users’ use of video objects versus other modes of retrieval during multiple-iteration searching. Results of this experiment show that although object searching is used far less than text searching in the first iteration of a user’s search it is a popular and useful search type once an initial set of relevant shots have been found. 相似文献

Ethical codes in the digital world: comparisons of the proprietary,the open/free and the cracker system 总被引：1，自引：0，他引：1
Jukka Vuorinen 《Ethics and Information Technology》2007,9(1):27-38
The digital world provides various ethical frames for individuals to become ethical subjects. In this paper I examine – in
a Foucauldian and Luhmannian way – the differences between three systems of communication: the proprietary, the open/free
and the cracker system. It is argued that all three systems provide a different set of ethical codes which one can be subjected
to. The language of each system is restricted and they cannot understand each other, they merely consider each other as the
environment. The systems generate a diversity of ethical codes as they give different shapes to digital objects. To proprietary
software companies digital objects are an instrument of financial profit. The free software/open source movement emphasises
transparency; the end user must be able to view and alter the source code. The cracker scene sees digital objects in a different
way. For this particular system, only copy-protected digital objects are appealing. Copy protection binds its target to the
world of matter. Breaking the protection is the ultimate challenge and a way to gain honour and status inside the cracker
scene. A copy-protected digital object is simultaneously an utmost example of the hidden source code (the open/free system),
a perfect artefact that can be owned and sold (the proprietary system) and a challenge to be cracked (the cracker system). 相似文献

Recently, the Korean popular (K-Pop) music industry has grown into a popular subculture among teenagers and young adults worldwide, which resulted in widespread interest in the fashion and style of idolised Korean singers and groups. Although English social media websites provide some content related to K-Pop, these websites lack diversity and rapid updating of information compared to local Korean websites. This study introduces a K-Pop knowledge graph, which is the basis for describing various objects and their relationships. All contents of the knowledge graph can be distributed and shared across various applications. To do so, this study proposes a semantic data model to represent a comprehensive profile for singers and groups, their activities, organisations and entertainment content. The knowledge graph is created by aggregating a set of relevant datasets from various data sources. In addition, Gnosis, which is a news application, demonstrates how this knowledge graph can be used in a real-world service. 相似文献
