Which of the following Chinese databases is more important in sci-tech novelty retrieval?

Deng Yong, Zhang Xian, Chengdu Literature Information Center of China Academy of Sciences, Chengdu, Sichuan Key words: sci-tech novelty retrieval; Database; Circle classification number: document identification number: document number:? Sci-tech novelty retrieval refers to the retrieval of retrieval database and traditional Chinese medicine literature database by novelty retrieval institutions according to the requirements of novelty retrieval commission. Verify the novelty of the scientific and technological content of the new project. At present, the understanding of patent database of novelty retrieval in China mainly means that there were several versions of the patent database of novelty retrieval project science China before the novelty retrieval commission date. Some or all of China National Intellectual Property Administration's technical contents have not been published in domestic and foreign publications, but those introduced by Intellectual Property Press have been published by China Patent Database Retrieval Department. In the actual novelty retrieval work, people mainly search the CD-ROM version of the literature and the CD-ROM version of the China patent specification database to provide librarians with relevant literature. The novelty retrieval quality of literature retrieval has improved the abstract and sovereignty basis of all patent applications accepted since 1998. In order to ensure the quality of literature retrieval, we must first select authoritative information, such as items, legal status and the full text of instructions. National knowledge is the best retrieval tool to meet the retrieval needs. Next, the author briefly introduces and compares some databases commonly used in novelty retrieval, including all China patent documents published since, according to the experience of novelty retrieval in China for more than ten years provided by his own patent office website:/. Information, including descriptions of entries in China periodical database and abstracts of three patents, namely invention, utility model and design, allows you to browse various specifications of full-text data view design graphics and Chinese periodicals commonly used in foreign sci-tech novelty retrieval and literature retrieval for free. There are mainly the following types of libraries. First of all, Tsinghua Tongfang's China Journal will find a CD-ROM retrieval literature database by comparing all the above patent databases. Since 1990, the domestic energy is greater and the retrieval channels are more comprehensive. From this point of view, the CD-ROM version should be the first choice for the full novelty retrieval of core periodicals and periodicals with professional characteristics. But the update frequency of CD version is slow. Because of the article, its biggest advantage is that online data is updated daily, which is timely. Therefore, in order to avoid missing the latest patent application, the online version should be supplemented after searching the disk version of Guanger, the full-text database of Chinese sci-tech periodicals in Chongqing Weipu. The latest published statistics. Since the beginning of this year, the collection of more than 10,000 kinds of periodicals shows that in the past year, the online version of China Patent Database has published more than 10,000 articles, covering almost all domestic literatures, with an average of nearly 10,000 times a day, and the number of visits accounts for the national Chinese periodicals, accounting for an absolute advantage in the number and age of periodicals collected. % of the total visits to the website of the Intellectual Property Office. But national knowledge is more suitable for retrospective retrieval. Thirdly, the Digital Intellectual Property Office of the online patent retrieval system of Wan Fang Data System has a fairly regular full-text database with equipment and bandwidth. Libraries are limited by domestic digital periodicals. For users who browse or download patent specifications beyond the basic daily life and integrate related pages such as China scientific papers and citation databases, it is best to order patent CDs or access some contents in other charging databases. At present, there are three periodicals and basic patent websites. This book includes statistical source journals of natural science and social science in China, and there are some other China patent retrieval tools on the Internet, such as core journals. Each of the above databases has its own characteristics. If conditions permit, when searching the New Intellectual Property in China sponsored by China National Intellectual Property Administration Intellectual Property Publishing House, it is best to search two or more databases together to improve the total patent rate of the search network://. And China National Intellectual Property Administration. Search and Consultation Center China Patent Information Network://. Due to the weakness of professional indexing in comprehensive database and the trap of Wan Fang data system://. In the actual novelty retrieval, novelty retrieval personnel can use websites such as ../to display specific novelty retrieval items. Among them, the first two can search book title records for free, and choose different professional search databases as supplements. For example, with abstracts, but full-text and legal status retrieval will be charged; However, Wanfang can choose China biomedical literature for novelty retrieval of Chinese medicine, with full charge. Date of receipt of foreign periodical databases: when novelty retrieval, authoritative databases in related fields should be given priority. About the author: Deng Yongyi, male,/Chongzhou native, undergraduate, associate researcher, commenting Wei's foreign language databases are generally commercial fee databases, such as many articles. American Chemical Abstracts, but there are also a few open free data, VIP information, Volume I, chinese journal of medical library and information science,,,,, such as. Full-text link function has been introduced, and the most commonly used databases for retrieval results novelty retrieval are: direct link to full text. In addition, there are many famous websites such as international science and technology publishing houses, publishing houses and publishers. Journals have been launched and so on. In addition to these databases, multi-abstract free retrieval and full-text paid use services. Some institutions also include conference papers, scientific and technological reports, dissertations, etc. , and some also provide online original delivery service that also realizes two-day express delivery function. Including patents. This provides a resource guarantee for the smooth progress of novelty retrieval. It is impossible to retrieve all the databases in every novelty search. Usually, the international patent database selects the appropriate database according to the professional field of novelty retrieval project. The patent administrative departments of the United States, Japan, Russia, Canada and other countries should first analyze the novelty retrieval project to determine which disciplines or cross-cutting fields the project involves and the provisions of the World Intellectual Property Organization on the Internet. Then, according to the patent database of our country and our organization, the experience of the European Patent Office in using the database and the communication with the project researchers, we also provided a number of national streams including 10 member countries, and initially selected which databases to use. At this point, the novelty retrieval personnel obtained the patent information in advance. These international patent databases can basically know the scope of the database, so searching this option is free, and many also provide free downloads of patent specifications. Quite important. For example, they have a wide collection range and many retrieval ways, and are important information sources for novelty retrieval. The report is fast and faithful to the original text, so it is the most important retrieval tool for searching chemistry and chemical literature. Because of novelty retrieval, it is usually not only the most important retrieval tool for a country or a patent group. However, many people don't know the actual weaving information. Therefore, when choosing a database, we should first choose a database system that can contain many other disciplines, such as life science, physics, and secondary retrieval of most patent information. In the above-mentioned free patent database, only the agriculture and molecular biology of the European Patent Office meet this requirement. Therefore, many professional novelty retrieval projects do not need to look up rules, and they can obtain the required documents through retrieval. Because of the huge amount of information, the patent system is likely to miss important information. Convenient and so on. However, in the case that international online retrieval is still widely used, the searcher's purpose is to make the patent information more popular and civilian, and the main targets are the general public and small and medium-sized enterprises. Therefore, it is impossible for database retrieval to do a retrieval scan with documents, which may be professional and rigorous. In fact, developers also confirm which databases to search mainly by voice. Now it is clear on the Internet that this library is only the first step to meet users' patent information needs, such as similar services. If the website://.. sing it, it provides free pre-inspection, which can be related to business decisions and needs to seek more professional retrieval. Therefore, it can help users to know which databases of the system contain but cannot meet the needs of sci-tech novelty retrieval, nor can it be regarded as a complete official patent information resource. Content related to user issues. For example, about "to carry out novelty retrieval, you must choose authoritative information sources." The project may not know which numbers to retrieve in advance, which means that the information itself is accurate, and it also refers to the free preview interface that you can log in at this time. In several possible related fields, such as, and, the information must be satisfactory, otherwise it will be incomplete and inaccurate, and information with ""as the search term will not be obtained. The authoritative patent retrieval tool was first published by derwent Company. Searching the database recently, you will find that the results appear more in the previous database years, derwent and; The online version of derwent patent jointly launched by the company is articles, articles and databases. As a professional retrieval tool, retrieve patent information and reports; Then, wait. Through a complete discipline, comprehensive information and powerful search work, we know that this project should mainly be search and database. Yes In particular, its citation retrieval function can reflect the progress of basic research through the mutual citation relationship between papers and patents, which is conducive to determining different retrieval strategies from the perspective of retrieval strategies. When searching different databases, it is necessary to know how a basic research achievement becomes a patent, thus being protected by the respective characteristics of the databases. For example, how to protect and form potential commercial value, how to develop a patent from the initial research on searching for chemical substances or related issues of chemical substances in the database, and how to transform basic research into patents usually need to take the name of chemical substances or the registration number of chemical substances as methods and ways, so that novelty retrieval personnel can understand the technical retrieval entrance of scientific and technological novelty retrieval projects and obtain higher accuracy and recall. It is very helpful to find the technical background and judge the technical innovation of novelty retrieval projects. If the advanced retrieval mode of organic macromolecules with complex three-dimensional configuration cannot be determined, it will also be beneficial for novelty retrieval personnel to formulate accurate chemical registration numbers and search through molecular three-dimensional structure diagrams. Search strategy. Therefore, with the development and wide application of network in novelty retrieval, derwent patent database is an essential retrieval tool to obtain the full text of papers.
