#experienceexperience# Introduction Literature retrieval is a boring thing, but it is also a very important learning and search method. Learning to search for documents requires patience, a lot of time investment, familiarity with the use of various databases, and sometimes a little bit of software knowledge. The following are three excellent examples of information retrieval experience shared by Kao.com. Everyone is welcome to pay attention.
Information retrieval experience (1):
Through this period of retrieval and learning, I found that my professional knowledge is still very poor and needs to be strengthened in my future study and life.
Literature retrieval is a boring thing, but it is also a very important learning search method. Learning to search for documents requires patience, a lot of time investment, familiarity with the use of various databases, and sometimes a little bit of software knowledge.
In the past, when I wanted to look up information, I knew Baidu and Google. Literature search opened up a new space and a new field for me, allowing me to easily obtain accurate and useful materials. For example, when we were doing course design before, we had to consult a lot of relevant information about majors. Now we don’t need to borrow so many books, reports or journals everywhere. We can get accurate information by just inputting the relevant information into the database. Useful information, so quick and convenient.
During the study process, I found that I was easily irritable. Whenever I can't find or quickly master the search skills, I become very irritable. This must be gradually improved in future studies. For a college student who is about to enter the society to participate in work or scientific research, He said that this is not a situation that should happen. I must strictly demand myself and lay a solid foundation for future work and study.
Literature retrieval is a very important and useful knowledge, and it is also a very profound knowledge. What I have learned now is only a little bit. But through continuous learning and accumulation, with the help of the methods taught by the teacher, I believe that I can make progress little by little until I can master it skillfully.
If you persevere, you must be able to learn well, learn well, and learn well!
Information retrieval experience (2):
Before I knew it, I had already taken the "Literature Retrieval" course for a semester. Through this semester of study, I I learned a lot of knowledge that will be useful in my future life. One day after another, I learned the application of eleven databases: CNKI, VIP Data, Wanfang, Chaoxing Digital Library, China Patent Information Network, and China Standard Full-text Database. Learning to use these databases will help me in searching for documents in the future. Gave great convenience.
Now is an era of information explosion. There are tens of millions of information around us, and the update speed of this information is very fast. How can we find the information we are looking for accurately and quickly? This goal can be achieved through the learned database.
Although the database has brought us a lot of convenience, we still need to study carefully if we want to use it skillfully, because we must discard useless information while looking for useful information. Before studying, I also searched some things on search engines such as "Baidu" and thought that searching for literature was simple. However, after a semester of study, I realized that my previous ideas were wrong. There is a lot to know about using a database to search for literature. For example: it is necessary to understand that each database has its own characteristics, to grasp the correct keywords, etc. The most important thing is to grasp the correct keywords, because the documents retrieved by entering different keywords will be very different. Choosing the correct keywords will greatly improve the speed and quality of the search, so you must find the documents you want quickly and accurately. You must choose good keywords, so choosing good keywords is the first thing you should learn when using a database.
I learned through studying and surfing the Internet that the scope of VIP Chinese in Chinese search is smaller, mainly journals; Wanfang Dissertation Full-text Database, the quality of the papers in this database is relatively high, and the search results are also Very detailed, including: paper title, author, major, supervisor, unit, classification number, keywords, abstract, etc.; Chaoxing electronic books are very useful, and many classic books can be found in Chaoxing Library; China The Patent Information Network is a very useful database for searching information related to various patents; in the Chinese standard full-text database, users can view the full text of the retrieved information for easy use; EBSCO is a private company in the United States and the world's oldest One of the companies that launched the full-text online database retrieval system, it can bring more than 100 full-text databases and secondary literature databases: the academic journal full-text database and the commercial resource integrated full-text database are the world's comprehensive academic cross-field databases, bringing nearly 4, The full text of 700 high-level academic publications, including more than 3,600 expert-reviewed publications. The collection spans nearly every academic research field and provides information dating back to 1975. This database is updated daily through EBSCOhost; SCI is an internationally renowned and authoritative database. In this database, we can find papers and research results in various fields, making it easier for us to understand the latest developments in technology. SCI is a very useful one A database that contains the best articles in basic disciplines in the world. Springer Publishing Company is the world's largest German publishing company. Its online publishing system, SpringerLink, includes journals, series, books, reference books and other document types. The information covers mathematics, physics and astronomy, chemistry, medicine, life sciences, engineering technology, computer science, environmental science, geography, economics, law and other disciplines, many of which are core journals.
In short, after this semester of study, I have a deeper understanding of the literature retrieval course, and I have a certain grasp of the key and difficult points of how to choose keywords. In this era of information explosion, we must master as much information as possible, enrich and improve ourselves as much as possible, so mastering the application of databases will be very beneficial in our future lives.
Information retrieval experience (3):
After studying the course of network information retrieval, I have learned and become familiar with its application, and gained a lot of experience and insights.
Through the study of information retrieval, I not only truly understood the profound meaning of information retrieval, but also learned how to choose the correct search terms to form a retrieval strategy for retrieval. In the actual search process, there are not many situations where only one search term can meet the search requirements. Usually we need to use multiple search terms to form a search strategy to meet the requirements of more complex topics composed of multiple concepts. For the method of document information retrieval, the most important thing is the selection of keywords, that is, the selection of search terms and search strategies. Accurate search word selection can not only save time and improve search speed, but also greatly improve the quality of search results, making it easier to find the data or literature you need.
Book search tools are convenient for searching, but sometimes are limited by publication time and often cannot reflect the latest information. Journal-style search tools can reflect the latest data, but due to space limitations, they cannot fully reflect the historical data of the data. When searching for subject-specific information, the first choice is a professional search tool, because it reflects the literature in the subject area, is highly specific, and can save time and energy. But at the same time, we should also pay attention to the use of comprehensive search tools. Comprehensive search tools can reflect information from various disciplines and expand knowledge and horizons.
There is a lot of penetration between modern disciplines. You can sometimes get unexpected gains by checking comprehensive search tools. Especially some domestic search tools are often organized by classification, and some interdisciplinary documents are often scattered in in different categories, so more attention should be paid to using comprehensive search tools.
When searching, attention should be paid to the combination of thematic bibliographies and comprehensive bibliographies, thematic indexes and comprehensive indexes, and professional databases and comprehensive databases. Chinese search tools, such as CNKI and Wanfang Data Resource System, can only reflect domestic research results. Pay attention to making full use of foreign language search tools such as EBSCOhost-foreign language journal full-text database and full-text electronic journals to obtain the latest research in the world. dynamic. Only by understanding the research trends at home and abroad can the paper reach a higher level.
After learning information retrieval, I have an understanding of the sources of knowledge I want to master. In life, I can find the information I want through information retrieval. This course has benefited me a lot, not only because it is a very important learning tool, but also a very good cultural quality that contemporary college students should possess!
