Abstract:

世界各国精神疾病患者数量逐年上升,覆盖地区逐年增多,中国是精神疾病发病重灾区。国际上非常重视精神疾病治疗药物的研究,目前临床使用广泛且疗效优良的原研治疗精神疾病药物几乎被大型跨国制药企业垄断。本研究以精神药物专利申请量为评价指标,分析中国在精神药物研发方面的创新性。结果提示:1) 国内精神药物研发相对滞后,中国的制药业与发达国家和地区相比存在较大差距,国内制药企业在精神药物研发方面进行完全自主开发新药,在今后相当长时间内仍有一定难度;2) 通过对跨国公司专利到期时间的分析,仿制药开发和生产是国内在精神药物研发方面的方向之一。为了填补精神疾病药物研发的空白,缩短与国际间差距,我国应加强精神药物的创新和仿制力度。
Currently the number of mental illness increased in each countries and the coverage area has increased every year, where China is the hardest area. The international community attaches great importance to the study of antipsy-chotic drugs, which excellent drugs, which are widely used in clinical and showed efficacy, monopolize by large multi-national pharmaceutical companies. This study analyzed the innovativeness on antipsychotic drugs in China, with its patent application for evaluation index. The results indicated that: 1) The development of domestic antipsychotic drugs were relatively dropped behind, in which there was a considerable gap compared with the pharmaceutical industry in China and developed countries, and the domestic companies were still more difficult to complete self-development of new drugs for quite a long time; 2) Generics development and production were the direction of domestic antipsychotic drugs, by analyzing the multinational patent expires time. In order to fill our gaps in antipsychotic drugs market, we should strengthen efforts in antipsychotic drugs of innovation and imitation.

Abstract: 如何快捷、准确、全面地检索互联网信息是互联网时代的重要问题。网络新闻比传统纸质媒体新闻速度更快、内容更丰富、形式更灵活生动,正逐渐取代传统新闻媒体成为很多人获取新闻信息的主要途径。然而,面对快速更新的大量新闻信息,传统的手工分类方式无法满足用户的需求。新闻的主要内容一般都是以文本的方式呈现,因此,利用文本自动分类技术对网络新闻进行自动分类是解决手工新闻分类问题的一个有效途径。由于网络新闻信息形式多样,很多新闻内容完全是由图片或者视频组成,不包含文本内容。本文提出通过新闻标题对网络新闻进行分类的方法,比通过内容进行分类的方法分类速度更快,并且有更强的适应性,可对无文本内容的新闻(如图片新闻、标题新闻等)进行分类。本文创建了基于标题的文本分类模型;从网络上获取新闻语料,验证模型的工作情况;并通过与基于内容的文本分类方法比较,验证基于标题的文本分类模型的优劣。本文构建了基于标题的两步分类系统,所提出的类别唯一特征,对于可分样本可以实现高分类准确率。
Retrieving online information efficiently becomes a crucial issue in nowadays online experience. Compared with traditional news in paper form, online news are faster, more convenient and more flexible. It is a trend that online news are replacing their traditional counterpart and becoming the most common way for people to obtain daily information. However, the volume of frequent updated news becomes so large that the traditional manual news classification cannot meet the needs of online users. One of the solutions for this will be applying automatic text classification technologies to classify online news. Many IT companies are developing automatic news classification systems. There are different forms of network news. Some of the news are composed mostly by graphics or videos instead of text and therefore not able to be coped with by classic text classification. A new approach of news classifier based on news titles is proposed to dealing with such news. In this paper, the title based classification model was created. The model was evaluated by a built corpus and compared with contents based classification. A two-phase news classification system is constructed and category key feature is proposed.
