Towards On-line Automated Semantic Scoring of English-Chinese Translation

Described and exemplified a semantic scoring system of students' on-line English-Chinese translation. To achieve accurate assessment, the system adopted a comprehensive method which combines semantic scoring with keyword matching scoring. Four kinds of words-verbs, adjectives, adverbs and "the rest" including nouns, pronouns, idioms, prepositions, etc., are identified after parsing. The system treats different words tagged with different part of speech differently. Then it calculated the semantic similarity between these words of the standard versions and those of students' translations by the distinctive differences of the semantic features of these words with the aid of HowNet. The first semantic feature of verbs and the last semantic features of adjectives and adverbs are calculated. "The rest" is scored by keyword matching. The experiment results show that the semantic scoring system is applicable in fulfilling the task of scoring students' on-line English-Chinese translations.     

论道德规范确立的缘由

作为一种具有独特地位和作用的社会规范,道德规范的确立有其缘由.首先,道德是人类生存与发展需要的产物.人对道德的需要来自集体生存的需要.道德的产生、发展以及发挥作用的方式、程度,都与人的需要密切相关.其次,道德是保障社会有序运行的手段.如果没有道德的规范约束作用,各种利益关系就不能得到有效调节,整个社会生活将陷入一种无序、混乱的状态.再次,道德是个体立身行事的依归.道德规范建立并为大家所接受之后,大家就可依规范而行事,在行动上保持相对的一致,从而获得相对的自由,创造自己的价值人生.
