1. Literature information retrieval summary report
Entering the senior year, I am about to write my graduation thesis, but I know little about literature retrieval. Listening to the teacher's literature retrieval class brought me a lot of gains. Learning literature retrieval is not only of great significance for us to write our graduation thesis, but also of great help to our future life and study. The course of scientific and technological literature retrieval and thesis writing is one of the most practical courses. As a tool, literature retrieval can inherit, develop and innovate the previous research through the knowledge of others, 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. Through the introduction of the teacher and the study of ppt left by the teacher, I not only learned the basic knowledge of information retrieval, such as literature can be divided into periodicals, patents, conference materials, dissertations, scientific and technological reports and so on. , but also learned a lot of retrieval systems, such as VIP database, China periodical full-text database, Wanfang database and so on. Wanfang Database is a large-scale network database developed by Wan Fang Data Company, covering periodicals, conference minutes, papers, academic achievements and academic conference papers. The development company-Wan Fang Data Co., Ltd. is the first joint-stock high-tech enterprise with information service as its core in China, and it is a comprehensive information service provider integrating information resource products, information value-added services and information processing solutions in the Internet field. It is characterized by an option for experts and scholars. If you are interested in a certain aspect, you can go directly to this edition and hide the words 10707 here. It can also be used for other problems. According to the experience of retrieval, we can scientifically sort out the materials and documents in our hands, so as to facilitate future search and reference. Literature retrieval course has cultivated our information literacy, made us learn the most valuable knowledge and laid a solid foundation for our lifelong learning.

Through the study of this semester's literature retrieval course, personal feeling is a practical course. Although this course is a professional elective course, its use is related to many courses in the future. Studying this course seriously will benefit us a lot. It is not only a very important learning tool, but also a good cultural quality that contemporary college students should have. Literature retrieval, as its name implies, refers to the process of organizing and storing information in a certain way and finding out relevant information according to the needs of information users, so its full name is also called information storage and retrieval, which is information retrieval in a broad sense. Narrow information retrieval only refers to the second half of the process, that is, the process of finding the needed information from the information set, which is equivalent to what people usually call information search.
Today's society is a highly information-based society, and people need a lot of information to carry out various activities every day. Network has become a very convenient way of information inquiry. As far as students are concerned, all colleges and universities have their own libraries, but only paper books can't meet the needs of students, so e-books in colleges and universities have played a great role. By combining paper books with e-books, students can easily find the documents they need. In addition, students can use many websites to query related information, and these retrieval methods can be learned in the course of literature retrieval. More importantly, through the study of this course, we can improve and improve the efficiency and quality of our literature retrieval, and avoid the waste of time and resources caused by our ignorance of retrieval methods and tools.
Personally, I have made great progress in literature retrieval. Before, I seldom searched for documents in the database of school collections. In many cases, I borrow paper resources from the library. Sometimes books are borrowed, and sometimes I can't borrow the books I want at all, which makes it difficult for me to finish the relevant homework. In addition, I mostly use web pages to find relevant information, but I am not very familiar with the technology and methods of finding documents, which eventually leads to my unsatisfactory results. After learning literature retrieval, I understand a truth. In the actual retrieval process, only one search word can meet the retrieval requirements. Usually, we need to use multiple search words to form a search strategy to meet the requirements of more complex topics composed of multiple concepts. For the methods of literature information retrieval, the most important thing is the choice of keywords, that is, the choice of search words and search strategies. Accurate selection of search terms can not only save time and improve retrieval speed, but also greatly improve the quality of retrieval results, making it easier to find the data or documents you need. At the same time, the study of literature retrieval made me form the habit of learning independently with the help of these databases. As long as it is necessary, I will look up what I am interested in in these databases and enrich my comprehensive knowledge. It can be said that through the study of literature retrieval, I learned a lot of things I didn't know before. I didn't know where to look when I needed to study materials before, but now I don't have to be at a loss. The powerful retrieval function and rich information resources contained in various databases have provided me with great help.

1. Familiar with scientific and technological information retrieval. Scientific and technological information retrieval can help people to acquire the knowledge they need quickly, correctly and comprehensively, save retrieval 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 be familiar with 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 are often easy to succeed, while others are not. 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 specific 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. At present, the development of computer technology makes it possible to automatically build large-scale indexes. There are two different retrieval strategies, namely, computer-centered information retrieval and human-centered information retrieval. In people's life at the moment, computers are very common, 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: at the lower stage, the earliest retrieval reference book in China is Han Shu Yi Zhi. At that time, the retrieval reference books were mainly book catalogues, which only served 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 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. After the birth of the first electronic computer in xxxx, 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.
Second, the harvest of scientific and technological information retrieval
Information retrieval is a method and means to find information, which enables people to find the information they need quickly, correctly 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 lifetime is learned on campus, and most of it should be acquired continuously at work; It helps researchers to continue 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 administrator in the governance work, the correct choice made by the operator in the management policy and the correct judgment made by the businessman in the negotiation, as long as the information can be obtained in a timely, correct and comprehensive manner, it will be as successful as possible. People living in the information society can master information retrieval technology and use it flexibly, so that they can win in the fierce social competition, improve our quality of life as much as possible and promote social progress. In view of the previous retrieval, I realized that even if it is successful, it is only a small part of the inter-network retrieval in information retrieval, which is a drop in the bucket at present. What's more, it is a completely successful network retrieval, processing tens of thousands of data. When I often get the data I need, 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!
It should be conceivable how you feel about learning information retrieval at this moment. 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 campus library. I understand that the culture of the library is most of the culture in the university, which is different from ordinary high schools.
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 the publishing time and often cannot reflect the newly published materials.
Third, the application of information retrieval
Periodical retrieval tools can reflect the newly published materials, but due to the limitation of space, they cannot fully reflect the historical materials of the materials. 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 also pay attention to the use of comprehensive retrieval tools. Because comprehensive retrieval tools can reflect the information 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. In retrieval, we should pay attention to the combination of thematic bibliography and comprehensive bibliography, thematic index and comprehensive index, and professional database and comprehensive database. Chinese retrieval tools can only reflect domestic research results, so we should make full use of foreign retrieval tools to obtain new 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 find a bibliography, you should not only look for the national bibliography and China national bibliography in China, but also look for the bibliographies of American BIP and British BNP, so as to grasp the worldwide research trends.
In the process of studying information retrieval course, I am not familiar with information retrieval, but I can basically use the knowledge in information retrieval to find the articles or books I want. In every practical course, I can find relevant books, which have a good application in practice. This is very helpful for us to write our graduation thesis in the future, and even we need to use this knowledge in our work.
In view of the vast amount of information resources, if you want to find the useful information you need quickly and accurately, you need to pay attention to summarizing and mastering some retrieval skills, analyzing retrieval data and choosing a suitable search engine in retrieval practice. Accurately express retrieval requirements and master some retrieval skills in colleges and universities. Due to the diversity of network databases, the scope of each retrieval system. The search problem is different. So, don't give up easily when looking for failure for the first time. You can rearrange and combine search words in a new way, add or delete search words, add or change search logic symbols, or replace them with synonyms and search again, which will generally get better search results.
After studying the course "Modern Sci-tech Information Retrieval", I have an understanding of the source 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!
