Sticks and stones and words that harm: Liability vs. responsibility, section 230 and defamatory speech in cyberspace

This article explores recent developments inthe regulation of Internet speech, inparticular, injurious or defamatory speech andthe impact the attempts at regulation arehaving on the `body' in the sense of theindividual person who speaks through the mediumof the Internet and upon those harmed by thatspeech. The article proceeds in threesections. First, a brief history of the legalattempts to regulate defamatory Internet speechin the United States is presented; a shortcomparative discussion of defamation law in theUK and Australia is included. As discussedbelow, this regulation has altered thetraditional legal paradigm of responsibilityand, as a result, creates potential problems forthe future of unrestricted and even anonymousspeech on the Internet. Second, an ethicalassessment is made of the defamatory speechenvironment in order to determine which actorshave moral responsibility for the harm causedby defamatory speech. This moral assessment iscompared to the developing and anticipatedlegal paradigm to identify possible conformityof moral and legal tenants or to recognize theconflict between morality and law in assigningresponsibility to defamatory actors. Thisassessment then concludes with possiblesuggestions for changes in the legal climategoverning the regulation of defamatory speechon the Internet, as well as prediction of theresult should the legal climate continue todevelop on its present course. This is not tosuggest that all law, or even the law ofdefamation, be structured to reflect thesubjectivity of a moral construct, but since itis the authors position that the legalassignment of liability in online settings ismisaligned, this reflection can serve asbeginning reassessment of that assignment.     

Dependency structure language model for topic detection and tracking

In this paper, we propose a new language model, namely, a dependency structure language model, for topic detection and tracking (TDT) to compensate for weakness of unigram and bigram language models. The dependency structure language model is based on the Chow expansion theory and the dependency parse tree generated by a linguistic parser. So, long-distance dependencies can be naturally captured by the dependency structure language model. We carried out extensive experiments to verify the proposed model on topic tracking and link detection in TDT. In both cases, the dependency structure language models perform better than strong baseline approaches.     

游戏平台入侵检测技术研究

网络安全问题是一个十分复杂的问题,涉及到电子商务、信息交换和游戏服务器。入侵检测与防御技术作为新一代网络信息安全保障技术,它主动地对网络信息系统中的恶意入侵行为进行识别和响应,不仅检测和防御来自外部网络的入侵行为,同时监视和防止内部用户未授权活动和误操作行为。本文提出了针对游戏服务器的入侵检测方案,在一定程度上缓解了黑客攻击游戏服务器的行为。

Topic discovery based on text mining techniques

In this paper, we present a topic discovery system aimed to reveal the implicit knowledge present in news streams. This knowledge is expressed as a hierarchy of topic/subtopics, where each topic contains the set of documents that are related to it and a summary extracted from these documents. Summaries so built are useful to browse and select topics of interest from the generated hierarchies. Our proposal consists of a new incremental hierarchical clustering algorithm, which combines both partitional and agglomerative approaches, taking the main benefits from them. Finally, a new summarization method based on Testor Theory has been proposed to build the topic summaries. Experimental results in the TDT2 collection demonstrate its usefulness and effectiveness not only as a topic detection system, but also as a classification and summarization tool.     

跨文化交流与接辞的形成——中日语言中“～的”的历时态研究

＂～的＂是在日语中使用频率高、用法多样、意义丰富的汉语系接辞之一。迄今为止,对于＂～的＂的共时研究比较多,尤其是从语法论的角度来进行的对比研究较多,而历时态研究较少。从语言交际的角度更深层次地、历时态地考察日语＂～的＂,同时,通过本研究来考察＂～的＂的发生、发展直至稳定的过程,从语法的角度进行归纳梳理,最终目的是希望为今后的日语语言学历时态的研究提供借鉴。     

大学生英语演讲中的隐含作者分析

对学生演讲稿的写作过程及成稿文本研究和分析表明,学生演讲中存在清晰的隐含作者。由于演讲是一种公共传播行为,学生演讲中的隐含作者与媒体叙事中的隐含作者较为相似,表现为更优秀、更强大的“第二自我”和文本所体现的、同时也是环境和社会意识形态所要求的价值观和道德观这两个层次。真实作者（学生）与隐含作者的互动、互融过程,就是学生进步、提高的过程。在演讲教学中正确运用隐含作者的作用,将对学生成长产生深远的积极作用。
