A 5-tuple based semantic information retrieval model is proposed, which includes the interoperation on the semantic layer, and a test process is given for this model. The recall ratio and the precision ratio of manufacturing knowledge retrieval are proved to be greatly improved by evaluation. Thus, a practical and reliable approach based on the semantic web is provided for solving the correlated concrete problems in regional networked manufacturing.展开更多

Any event structure can be represented through the 7S schema. ＂For some purpose, somebody does something for someone with some means, sometimes and somewhere＂. Therefore, an event consists of 7 conceptual domains： purpose, actor, action, object, facility, location and time. In the article, the main concepts of the 7 domains and over 20 semantic relationships between these domains are described in detail and illustrated by some examples.展开更多

The author＇s learning journey, while not unique, has not been an ordinary one. Initial academic failure to achieve in the school education system contributed to her choosing a life working on the land and harbouring the belief that she was unable to learn academically. Still, the author has gained a rich base of physical knowledge and experience through the traditional oral route including learning interpersonal communication through body language and vocal tonality. The author has used this intuitive knowledge to develop an arts practice where she explores the bio-cultural links between people and the lands they inhabit, creating works that aim to extend knowing through emphasising the experience and atmosphere of landscape. At this time, when our lives have become increasingly encoded and intellectually based, the author shares a belief with American philosopher Eugene Gendlin （b. 1926） that the ＂felt sense＂ can be developed in order to enable us to engage more fully with the world around us. The author explores this idea in her visual art but also realizes the need to express it in writing, both in order to reach a wider public and because of the possibilities offered by the written word to make public which is private and held deep within.展开更多
