Discussion 2

The following is the paper, just extract 500 words at will.

2 1 century is the era of knowledge economy and network. Searching and using information quickly, accurately, timely and effectively is a new requirement for information retrieval in the era of knowledge economy and network, and it is also a basic information literacy that people must have in the 2 1 century. In this era full of opportunities and challenges, information retrieval is also the key to our creativity or career success. The following is my brief talk about information retrieval.

Information retrieval can help people acquire the knowledge they need quickly, accurately and comprehensively, save the search time to the maximum extent, make our information retrieval process get twice the result with half the effort and make full use of information.

We are now facing a brand-new information society. With the rapid development of information technology and the rapid construction of information superhighway, information products have penetrated into various disciplines, and the output of information has increased exponentially. Information technology has become an indispensable means for human beings to understand and transform the world.

People living in today's society have to deal with information almost every day. Perhaps we have felt that some people often succeed in doing things, while others don't. This is largely because the former has a strong sense of information, can grasp more information and make correct judgments on what they do, so their success rate is relatively high. On the other hand, if the information awareness is poor and the information cannot be collected in time, the decisions made will often be biased and the success rate is not high.

Information retrieval method is a concrete operation method or means to realize retrieval purpose. There are two main ways of information retrieval, namely direct retrieval and indirect retrieval. In fact, many libraries still use this classification level to classify the collected materials. Now, the development of computer technology makes it possible to automatically build large indexes. There are two different retrieval strategies, namely, computer-centered information retrieval and human-centered information retrieval. Nowadays, computers are very common in people's lives, and people use computer networks to search more.

The development of information retrieval is developing with the progress of science and technology. The development stage of information retrieval can be divided into four stages: the primary stage, the earliest retrieval reference book Bielu in China was in the Han Dynasty. At that time, the retrieval reference books were mainly book catalogues, serving only a very small number of people. The second stage is manual retrieval, and the real development of information retrieval is after18th century. With the continuous development of science and technology, all kinds of information have greatly increased, and at the same time, various types of documents have been produced, such as books, newspapers, periodicals, meeting records and so on. Later, with the development of society, a complete manual retrieval tool-catalogue, index and abstract was gradually formed. The third stage is computer retrieval. With the development of science and technology, information retrieval is also changing. 1946 after the birth of the first electronic computer, it was quickly used to store and retrieve information. The fourth stage is the era of network retrieval. The appearance of network has changed our study, work and life, and made people really enter the information society.

Information retrieval is a method and means to find information, which enables people to find the information they need quickly, accurately and comprehensively in the vast ocean of information. It can be said that information retrieval is very useful for people's study, life and work. It can give full play to the role of human knowledge treasure house and is conducive to the development of intellectual resources; Information retrieval can improve efficiency, save researchers' time and reduce manpower or investment costs; The shortcut to acquire knowledge and the continuous growth of the basic knowledge of lifelong education are gradually accelerating the aging of the original knowledge. Some experts believe that about 10% of the knowledge used by college students in their life is learned at school, and most of it should be acquired continuously at work; It is helpful for researchers to inherit and learn from previous research results and avoid repeated research or detours.

In today's era of great information and extremely developed communication industry, it is more important to master information. As for the correct decision made by the manager in management, the correct choice made by the operator in management policy and the correct judgment made by the businessman in negotiation, as long as he can obtain information in time, accurately and comprehensively, he can succeed as much as possible. People living in the information society can master the information retrieval technology and use it flexibly, so that they can win in the fierce social competition, do their best to improve our quality of life and promote social progress. In the face of previous retrieval, I realized that even if it was successful, it was only a small part of network mutual retrieval in information retrieval, and now it is dwarfed. What's more, it is a completely successful network retrieval, facing tens of thousands of data. I often encounter the data I need, and I have experienced countless readings and countless times of error information screening. As far as finding the required topic is concerned, it is just a bitter fruit!

The feeling of learning information retrieval now should be imaginable. Although I don't study very well, there are many things I don't understand, but I can feel a lot from it, which I need to study for a long time or can't learn well for a long time. However, what shocked me most was the use of the school library. I understand that the culture of the library is the biggest part of the culture in the university, which is the biggest difference from studying in high school.

What I deeply understand is the atmosphere and quality of information retrieval. I like information retrieval very much, not only because it is a very important learning tool for me, but also because it is a good culture and quality I should have!

Book retrieval tools have the characteristics of convenient access, but at the same time, they are sometimes limited by publishing time and often cannot reflect the latest information. Periodical retrieval tools can reflect the latest information, but due to the limitation of space, they can't fully reflect the historical content of information. Professional retrieval tools are the first choice to find subject information. Because it reflects the literature of this subject, it is more specific and can save time and energy. But at the same time, we should pay attention to the use of comprehensive retrieval tools. Because comprehensive retrieval tools can reflect the contents of various disciplines and play a great role in expanding knowledge and vision.

There is a lot of infiltration between modern disciplines, and comprehensive retrieval tools can sometimes get unexpected gains. In particular, some domestic retrieval tools are often arranged by classification, and some interdisciplinary documents are often scattered in different categories. Therefore, we should pay more attention to the use of comprehensive retrieval tools. Attention should be paid to the combination of subject bibliography and comprehensive bibliography, subject index and comprehensive index, and professional database and comprehensive database in retrieval. Chinese retrieval tools can only reflect domestic research results, so we should make full use of foreign retrieval tools to obtain the latest international research trends. Only by understanding the research trends at home and abroad can the paper have a higher level. For example, if you want to search for bibliographies, you should not only look for national bibliographies in China and China, but also look for the bibliographies of American BIP and British BNP, so that you can grasp the research trends all over the world.

The course of scientific and technological literature retrieval and thesis writing is one of the most practical courses. The purpose of studying this course is to learn how to use information retrieval to search for the desired information fastest and most accurately. Literature retrieval, as a tool, can inherit, develop and innovate the previous research through the knowledge of others, and further develop our own research through the study and reference of research ideas and methods, which will be of great help to us in writing our graduation thesis in the future. Literature information is the basis of study and research work, and all kinds of study and research work will be carried out according to the literature information we collected. The richer the information resources, the greater the possibility of success in learning and research. Facing more and more literature resources, how to get the information you want with the least time and energy through effective methods? This requires the basic skills of literature retrieval, through which academic trends can be obtained; The answers to unknown questions can be found through literature retrieval; Literature retrieval can cultivate information awareness and improve self-study ability ... It can be said that students' usual study and graduation thesis writing are closely related to literature retrieval.

In this document retrieval course, through the teacher's introduction, I not only learned the basic knowledge of information retrieval, such as documents can be divided into periodicals, patents, conference materials, dissertations, scientific reports and so on. I also learned many retrieval systems, such as VIP database, China periodical full-text database, EI, EBSCOhost, SpringerLink, Superstar e-book, Founder Apabi e-book and so on. And we know the characteristics of various databases, such as: VIP database is dominated by periodicals, Wanfang dissertation database has diverse retrieval results, EBSCO is one of the first companies in the world to launch a full-text online database retrieval system, and papers and research results in various fields can be found in SCI, while Springer has included core journals in many fields.

In short, after this semester's study and the teacher's patient guidance, I not only learned about the course of document retrieval, but also learned how to search the information and materials I need in the database more quickly. But a short study is not enough. The constant updating of the database also reminds me to constantly learn and enrich myself, improve myself, learn more about the database, and prepare for my future life and development.

After studying modern information retrieval, I know all the sources of knowledge I want to master. In my life, I can find the information I want through information retrieval. I think this course really benefited me a lot!
