Literature retrieval has several functions in educational research:
1, which can provide the basis for selecting topics.
In the process of determining the subject, we must fully understand the existing research. What are the previous research results? How did they study it? Research focus? Research methods? What problems have been solved or basically solved? What problems have not been solved? What needs to be further revised or supplemented? What are the main differences on this issue at home and abroad? What's the point? How many are representative? Who is the representative? For topics that have not been involved by predecessors, we should understand the research value of the topic from the side by consulting relevant literature. Where can we start? What methods and means can be used? Can similar disciplines or topics be used for reference? All this, without the possession of literature, is unimaginable.
2, can expand the field of vision
Marx once compared the use of literature to standing on the shoulders of giants. Full possession of literature can broaden researchers' thinking, deepen their understanding of problems and stimulate deep thinking. Frequently consulting literature can stand at the forefront of the research field, track the latest research results and methods at home and abroad, get inspiration from them, find possible answers to questions, and make the research topic stand at a higher starting point.
3, can avoid unnecessary repetition.
A basic purpose of literature retrieval is to avoid duplication of work, problems solved by others, mistakes made by others, detours and improving research efficiency.
Document retrieval plays an important role in the whole research, and the value of research results is related to the quantity and quality of documents. In the absence of literature, research is often either blindly involved or repeated below the level, wasting manpower and material resources.
I don't know if the above content has solved your doubts.
Question 2: What is the function of literature retrieval? Information retrieval refers to the process of obtaining documents according to the needs of study and work.
The function is as follows, so:
Question 3: The significance of literature retrieval.
Literature retrieval is the basic means to obtain knowledge and information by using literature. This is of great significance to the needs of research and macro-decision.
1? Literature retrieval is a basic skill in reading and learning. Literature retrieval skills are an important part of intelligence. Whether in school or at work, we need to cultivate and train all kinds of intelligence. Mastering the method of literature retrieval is like having the golden key to open the treasure house of knowledge and the guide to boating in the sea of books, which is helpful to guide the way of learning and research, as Zhang Zhidong, a scholar in Qing Dynasty, wrote in Bibliography Q&A? As pointed out in "Simple Examples": "It is futile to read without knowing the essentials; Knowing that a book should be read without careful annotation will get twice the result with half the effort. " "When you enter the door, you get twice the result with half the effort." It can be seen that it is very important to master some knowledge of document retrieval-bibliography. Xunzi? The article "Encouraging Learning" said: "If you don't accumulate silicon, you will be thousands of miles away; Without a trickle, you can't become a river. " From the perspective of literature retrieval, the so-called "silicon step" and "trickle" are the accumulation of literature retrieval skills, the identification of retrieval tools and books, and the application of knowledge. For college students, it is the golden age to receive this skill training.
2? Literature retrieval is an integral part of scientific research. Scientific research begins with the investigation of topics and the mastery of information. Literature retrieval is helpful to grasp the progress of this research, open up new ideas, avoid duplication of work and raise the research level to a new height. The evaluation and appraisal of scientific research achievements also need literature retrieval-novelty retrieval activities to make correct conclusions. Especially under the condition of imperfect social science literature retrieval system, the level of literature retrieval ability often affects the value of scientific research results.
3? Literature retrieval is the forerunner of scientific decision-making. In the information age, economic management, political control, artistic creation and even the evolution of psychological state are all influenced by various social information. Only by mastering relevant information in time can effective management be realized. Therefore, literature retrieval is the primary work of scientific decision-making. Comrade * * *' s inscription "Developing information resources to serve the four modernizations" not only profoundly reveals that information is an important intellectual resource for macro-decision, but also points out the purpose of developing information resources. From the information development means, it is also a high summary of the significance of literature retrieval.
In a word, the ability of document retrieval is one of the indispensable intelligences for material civilization production and spiritual civilization construction. In a sense, the gap of national economic strength is, in the final analysis, the gap of national ability to absorb social information. Literature retrieval ability is an important index to measure the ability to deal with social information.
Question 4: Explain the function of information retrieval. If it's just a short answer, just choose the topic of each point. Information retrieval is the basic means to acquire knowledge and information. How to find the information people need effectively, quickly and accurately in the information ocean and make it an important resource has become an important demand of people in the information age. Therefore, information retrieval technology will play an increasingly important role in the information society. Mainly reflected in the following aspects:
1. can fully grasp the relevant necessary information and enhance the scientific decision-making.
Mastering certain necessary information is the first condition for conducting research and doing a good job, and it is also a necessary prerequisite for making correct decisions. Scientific decision-making comes from full knowledge and understanding of information, and information retrieval is an important way for decision makers such as countries, departments, units and individuals to obtain information. Therefore, information retrieval will make the decisions of countries, departments, units and individuals based on science, greatly increase the scientificity of decision-making and reduce the blindness of decision-making.
2. Improve the efficiency of information utilization and shorten the time of obtaining information.
Information retrieval can enable users to obtain information closely related to their needs in a short time, so that users have more time to complete more important work, thus greatly improving work efficiency.
It is beneficial for information users to get all the information they need.
Information retrieval often depends on one or more large information bases, which store a wide range of information. Through information retrieval, all the information needed by information users can be captured at one time.
4. Improve information literacy and scientific research success rate.
The so-called information literacy refers to having a strong sense of obtaining information, mastering the techniques and methods of information retrieval, and having the ability to identify and use information. The improvement of information literacy can enhance information awareness and be familiar with retrieval skills, which is conducive to the smooth development of scientific research and improve the success rate of scientific research.
5. Promote social progress and economic development.
Social progress and economic development promote the generation, circulation and use of information; On the other hand, the transformation of information production, circulation and use will promote the further development of society and economy.

Question 5: What role does literature retrieval have for contemporary college students? Very useful, when you graduate, you will use it to write papers and choose documents.
Question 6: What are the main ways of literature retrieval, including the following ways:
First, the author's way Many retrieval systems have an author index and an institution index, and patent literature retrieval systems have an patentee index. The method of searching from the names of authors, editors, translators and patentees or the names of institutions and groups by using these indexes is collectively called author method.
Two, the title includes title, title, title and other ways. Some retrieval systems provide retrieval methods by title, such as title catalogue and periodical catalogue.
Thirdly, the classification method searches documents according to the subject classification system. This method is based on the knowledge system, so it can better reflect the subject system, reflect the subordinate, derivative and parallel relationship between subjects and things, facilitate us to find documents from the subject range, and play an analogy role. Classified retrieval mainly uses classified catalogue and classified index.
Fourthly, the subject method searches the literature through the subject words that reflect the content of the literature. Because the thematic method can reflect all aspects of a theme, it is convenient for readers to conduct a comprehensive and systematic thematic study on a certain problem, thing and object. We can find all aspects of the literature on the same subject through the subject catalogue or index.
Verb (abbreviation of verb) refers to the reference or quotation attached to the document, which is one of the external characteristics of the document. The index system compiled by using this citation is called citation index system, which provides a method to retrieve cited papers from cited papers, called citation method.
Six, serial number method Some documents have specific serial numbers, such as patent number, report number, contract number, standard number, international standard book number, serial number, etc. The file serial number is clear, short and unique, which is used to identify some files. Based on this, various serial number indexes can provide a way to retrieve literature information in the order of serial number itself.
7. Codes compiled by using some codes of things, such as molecular formula index and ring index, can be retrieved from a specific code order.
Eight, special project method from the literature information contained or related terms, place names, names, organization names, trade names, biological generic names, years and other specific order to retrieve, can solve some special problems.
Question 7: Briefly describe the functions and basic methods of literature retrieval. Information retrieval 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 information, which is equivalent to what people usually call information search.
Computer information retrieval refers to the method of information retrieval by means of computer technology and modern retrieval means such as CD-ROM and Internet. Computer information retrieval, like manual retrieval, should be regarded as a basic skill of future scientific and technological personnel, and the training and cultivation of this ability is extremely important for scientific and technological personnel to adapt to the future society and cross-century scientific research. A researcher who is good at obtaining information from electronic information systems will certainly have more chances of success than those who do not have this ability. The American periodical POV, which reports the new lifestyle, also lists interactive network retrieval experts as one of the top ten hot jobs in the future. All these situations show that computer information retrieval is becoming more and more important, so it is worthwhile to give this technology to everyone.
Document retrieval is a very practical activity, which requires us to be good at thinking and gradually master the law of document retrieval through regular practice, so as to obtain the required documents quickly and accurately. Generally speaking, literature retrieval can be divided into the following steps:
(1) Define the purpose and requirements of the search.
(2) Select a retrieval tool
(3) Determine the retrieval mode and method.
(4) According to the literature clues, refer to the original literature retrieval method (1) and direct method.
Also known as common method, it refers to the method of directly using retrieval system (tool) to retrieve literature information. It is also divided into sequential investigation, reverse investigation and spot check.
(1) sequential search method
Sequential retrieval method refers to the method of using retrieval system to retrieve literature information from far to near in time sequence. This method can collect systematic documents of a certain discipline and is suitable for document retrieval of larger disciplines. For example, to know the initial age of a subject, we need to know the whole process of its development now, so we can use the sequential search method to start from the initial age and gradually find it in the near future.
(2) Backward search method
Reverse retrieval method is a method of literature retrieval by using retrieval tools from near to far, from new to old and from reverse time. This law focuses on recent literature. Using this method, you can get the latest information as soon as possible.
(3) Sampling method
Spot check method refers to the characteristics of the project, selects the most likely or most likely time period of document information related to the project, and uses retrieval tools to carry out key retrieval.
(2), backtracking method
It refers to the method of tracing the original texts (cited documents) one by one without using the general retrieval system, and then expanding the scope of literature information one by one from the list of references listed after these original texts, and tracing them one by one. It can snowball and get better retrieval results according to the citation relationship between documents.
(3), the cycle method
Also called subsection method or synthesis method. It uses direct method and backtracking method alternately in stages to learn from each other's strong points and cooperate with each other to obtain better retrieval results.
Question 8: What is the significance of learning information retrieval course? Xunzi, an ancient thinker and educator in China, said: "Those who cheat horses are not good enough, but lead thousands of miles;" He who carries a boat can't get water, let alone a river; A gentleman's life is the same, and goodness is illusory. "/kloc-samuel johnson, a British writer and lexicographer in the 0/8th century, also said:" There are two kinds of knowledge, one is what we know; The other is that we know where to find it. Courses such as the use of reference books, literature retrieval and utilization, and information retrieval are knowledge courses for discovering knowledge.
The function and significance of information retrieval are mainly reflected in the following three aspects.
(A) to avoid repeated research or detours
We know that the development of science and technology is continuous and inherited, and building a car behind closed doors will only repeat the labor of others or take detours. At the beginning of selecting a topic, researchers must conduct information retrieval to find out what others have done, what they are doing, who is doing it and how it is progressing. In this way, users can re-create on the basis of other people's research, avoid repeated research, and take fewer or no detours.
Save learners' time
The rapid development of science and technology has accelerated the growth of information and increased the burden of information collection for information users. Many scholars, after undertaking a certain project, also realize that they should look for information, but they think that "general survey" of information in the library all day is information retrieval, which wastes a lot of time, but rarely finds valuable information, and the recall rate is very low. Information retrieval is the foundation and necessary link of research work. Successful information retrieval will undoubtedly save a lot of time and make it have more time and energy for scientific research.
(C) is a shortcut to acquire new knowledge
College students have mastered certain basic knowledge and professional knowledge during their school days. However, "giving it to fish" can only be enjoyed for a while. If you master the method of information retrieval, you can learn by yourself, find a shortcut to absorb and use a lot of new knowledge, and guide everyone to a broader field of knowledge and explore the unknown world. It is said that "giving people fish" can be used for life.
There is a passage in front of the Berlin Library in Germany: "This is a treasure house of knowledge. If you master its key, all the knowledge here belongs to you. " The key here refers to the method of information retrieval.
Question 9: What is the main function of literature retrieval in educational science research? In the research of educational science, the function and significance of literature retrieval are mainly reflected in the following three aspects:
(A) to avoid repeated research or detours
The development of educational science has continuity and inheritance, and building a car behind closed doors will only repeat the labor of others or take detours. Repetition is the most taboo in educational research, because it is unnecessary waste. In research work, every link of any topic, from topic selection, experiment to results, is inseparable from information. At the beginning of the topic selection, researchers must conduct literature search to find out what other people have done on the project, what they are doing now, who is doing it and how it is progressing. In this way, we can re-create on the basis of other people's research, thus avoiding repeated research and taking fewer or no detours.
(b) saving researchers' time.
The rapid development of science and technology has accelerated the growth of information and increased the burden of information collection for information users. Literature retrieval is the basis and necessary link of research work. Successful document retrieval will undoubtedly save researchers a lot of time and enable them to spend more time and energy on education and scientific research.
(C) is a shortcut to acquire new knowledge
In today's reform and opening up, the knowledge-based talents trained by traditional education can no longer meet the needs of market economy under the reform environment. The new situation requires the cultivation of high-quality innovative talents. Talents with these abilities first need to have the ability of self-study and independent research. If we master the method of literature retrieval, we can learn from ourselves, find a shortcut to absorb and use a lot of new knowledge, and guide everyone to a broader field of knowledge and explore the unknown world. It is said that "giving people fish" can be used for life.
I hope I can help you!
