Analysis:
The role and significance of information retrieval are mainly reflected in the following three aspects.
(1) Avoid duplication of research or detours
We know that the development of science and technology is continuous and inheritable, and working behind closed doors will only repeat the work of others or make detours. For example, a research institute in my country spent about ten years to successfully develop a new process of "substituting magnesium for silver" and applied for a patent with confidence. However, a company in the United States had already obtained a patent for this process as early as the late 1920s. The instructions for this patent are stored in the local Science and Technology Information Institute [7]. The most taboo thing about scientific research is duplication, because it is unnecessary waste. In research work, every step of any topic, from topic selection to experimentation to results, is inseparable from information. Researchers must conduct information retrieval at the beginning of topic selection to understand what work others have done on the project, what work is currently being done, who is doing it, how the progress is, etc. In this way, users can recreate based on other people's research, thereby avoiding duplication of research and taking fewer or no detours.
(2) Saving researchers’ time
The rapid development of science and technology has accelerated the growth of information and increased the burden on information users to collect information. Many researchers also realize that they should search for information after taking on a certain topic. However, they think that spending all day in the library to "check" information is information retrieval. As a result, a lot of time is wasted, and not much valuable information is found. articles, the recall rate is very low. Information retrieval is the basis and necessary part of research work. Successful information retrieval will undoubtedly save researchers a lot of time, allowing them to spend more time and energy on scientific research.
(3) It is a shortcut to acquire new knowledge
In today's era of reform and opening up, the knowledge-based talents trained by traditional education can no longer meet the needs of the market economy in the reform environment. The new situation requires What is cultivated is capable and creative talents. Talents with these abilities first need to have self-learning ability and independent research ability. College students have mastered certain basic knowledge and professional knowledge during their studies. However, "teaching him to fish" only allows him to enjoy it for a while. If you master the information retrieval method, you can learn it by yourself without a teacher, and find a shortcut to absorb and utilize a large amount of new knowledge, leading everyone to a broader knowledge field and exploring the unknown world. It is said that "teaching people how to fish" can be of endless use throughout their lives.
There is a passage in front of the Berlin Library in Germany: "This is a treasure house of knowledge. If you have the key to it, all the knowledge here belongs to you." The "key" mentioned here ” refers to the method of information retrieval.
