Abstract
With the fast development of the internet, netspeak has appeared and deeply shaped the life of netizens and even the common people. The initial research relating to the study of netspeak is limited to its generalization and origin. Netspeak has been classified as a kind of social or cultural phenomenon, reflecting chiefly the half-hearted attempt or intentional joking of the speaker. In recent years, the academic field’s increasing interest in hot netspeak witnesses a majority of study focusing on linguistics, analyzing the language structure of netspeak, language style and so on. Only a small number of scholars have begun to expound hot netspeak from perspectives like cognitive science, psychology, etc. This paper argues that cognitive semantics provides a framework for theoretical analysis on word meanings while centering on the guidance of cognitive science, mentality and psychology. Therefore, it is necessary to conduct a systematic analysis on hot netspeak under the framework of cognitive semantics. In addition to the metaphor theory which is constantly drawing attention from people, the prototype theory should also be regarded as the prime research paradigm. This paper endeavors to analyze netspeak on its generative process of the meaning, features of the meaning and its impact on the society and culture under the application of the prototype theory and metaphor theory by selecting out the hottest and most typical netspeak vocabularies.

随着网络的迅猛发展，网络语言也随之出现并广泛影响网民甚至是大众的生活。关于网络语言的研究最初仅限归纳整理以及追溯出处等，多半带着浅尝辄止或者戏说的成分，将其作为一种社会现象或文化现象研究。
近年来，学术界对网络热词的关注持续增长，大多数的研究集中在语言学领域，分析网络语言的构词法、语言风格等等，只有少部分人开始着手从认知学、心理学的角度阐述网络热词。本文认为,认知语义学能够从人们认知、思维和心理角度对词汇意义的产生与发展作出学理分析，因此，有必要对网络热词作一番认知语义学的系统分析。除了已经逐渐受到重视的隐喻理论，原型范畴理论也应成为研究范式。本文旨在运用认知语义学的原型范畴理论及隐喻理论，选取时下最热门和典型的网络词汇，深入分析其语义产生过程、语义特点及其对于社会、文化的影响。
