"Medical Science Information Retrieval Course" is a scientific method, which aims to cultivate students' independent learning ability, ability to update knowledge. In today's technology development change rapidly, the rapid growth of knowledge and knowledge of global communication network of the information age, covered the subject knowledge for students increasingly shows its importance and urgency of learning. Since the class began to gradually open in medical institutions of higher learning in China since twentieth Century 80 in the early 1990s, there are ten kinds of similar materials. Is mainly divided into 2 kinds, one kind is the teaching of medical information retrieval for clinical medicine and related professional, this kind of materials accounted for the vast majority of. This kind of material is introduced in detail in the database or specific search tools collection scope, retrieval approach and method as well as the processing of search results for information retrieval, but the basic principle, basic theory, basic methods, basic knowledge of the common problems. Another class of oriented medical information retrieval teaching materials science professional medical science and technology information, this kind of materials less proportion. This kind of material is mostly stay in manual retrieval tools and basic knowledge is introduced, and the basic knowledge of computer information retrieval, especially the network information retrieval and introduced the basic knowledge of the lower proportion. The current medical science information retrieval teaching content change rapidly, these materials is very difficult to adapt to the needs of medical science and technology information network under the environment of information retrieval teaching. In addition, medical informatics students and clinical medicine and related professional students in the aspects of training target, teaching contents and teaching hours there is a big difference. Therefore, the construction of teaching materials of high quality medical information technology to strengthen the strong sense of the times of the retrieval has become an important factor in professional medical science information retrieval course teaching to improve the quality of medical information in Colleges and universities. This textbook based on the biomedical field, specialty oriented medical information, is a comprehensive system of medical science and technology information retrieval and using the basic principles and basic theory, technical methods and comprehensive utilization of the professional teaching materials, content involves information retrieval technology, retrieval, information retrieval system, various tools and information resources, comprehensive utilization and so. Therefore, this textbook is innovative in the following aspects. 1 in order to cultivate information compound, applied and innovative medical talents as the goal, the overall design of the textbook. The book consists of 10 'chapter. In the "Three Basics" (basic theory, basic knowledge, basic skills) "five characters" (thought, scientific, advanced, enlightening, applicability) based on the principle of teaching material "update", "deeper" more refined "". As a medical information professional backbone course materials, "medical science information retrieval" completely and systematically introduces the basic principle, the basic medical science information retrieval theory, technology and method, various specific biomedical database included characteristics, retrieval approach and method as well as the scientific research application. 2 original textbook content. "Medical science information retrieval" is a relatively young curriculum, development and changes very quickly. The latest progress of textbook reflects the theory and technology of information retrieval, the rapid development of information technology and biomedical science followed the pace of change rapidly, and strive to new changes of comprehensive, timely, accurately reflect the medical science and the rapid increase of information resources, and biological medicine new information retrieval technology, theory and method. Not only focuses on various retrieval tools of network retrieval approach and method, but also increase the number of such as information retrieval model, ontology, search engine, the original integrated use of document acquisition, scientific research and project application, novelty and other new content.
This textbook based on the biomedical field, specialty oriented medical information, is a comprehensive system of medical science and technology information retrieval and using the basic principles and basic theory, technical methods and comprehensive utilization of the professional teaching materials, content involves information retrieval technology, retrieval, information retrieval system, various tools and information resources, comprehensive utilization and so.

(4) three (1rertiary Document): literature is the technical personnel on a certain subject, with the help of documents for two times, and make full use of the base of a large number of a literature, after reading, analysis, induction, generalization, writing a new literature. Mainly include: review (review), (comment), a review of progress (frogress, advance), (update) status, development trends (trend) and other journals and encyclopedias, Yearbook, manual reference book. Many academic journals are Piyou review column, and published devoted to the three literature periodicals are also more and more. The three documents have the information content is big, strong comprehensive nature, value etc.. By reading the documents for three times, can be more comprehensive understanding of a topic, a field of current research level, dynamic. With a document generation is different, the three document is a basic research materials with a literature of knowledge information, the further processing, consolidation, restructuring, make knowledge and information products more orderly. But because the three literature into the author's intelligence, therefore, belong to the intellectual product with a document. Characteristics of 4 science and technology literature information with the development of science and technology and the progress of human civilization is accelerating, science and technology literature information also showed corresponding changes, mainly manifested in the following aspects. (1) the amount is huge, rapid growth. According to reports, more than 100000 kinds of scientific and technical periodicals in the world, the number of papers published more than 4000000 papers per year. More than 4800 kinds of sci-tech periodicals in China every year, published more than 200000 articles. Both the number of periodicals, or the quantity of paper, each year to more than 10% of the incremental growth rate. In medical field, 3000 kinds of commonly used foreign language biomedical journals, biomedical journals published more than 1600. (2) language variety, but a cultural tendency. Before and after the Second World War, the world science and technology development center first moved to the America, English began to replace Devin and French became an international science and technology exchange language. Therefore, although the international science and technology literature style is various, but English accounts for the proportion is rise. Especially, the extensive use of the Internet, more accelerated this cultural trend. Many non English countries to conform to this trend, have to make a positive response, such as English medical journals published in Japan up to 150, even in the Japanese medical literature, English professional vocabulary, English chart also meet the eye everywhere. The number of China's publishing English journals have increased rapidly, and many academic journals, such as "Chinese Journal of surgery" "Chinese evidence-based medical journal" took first appeared as encouragement to absorb the English presentation. (3) the document distribution is concentrated and dispersed, but a special subject or album trend. In medical field, because the subject of professional specialization, comprehensive development, not only the medical literature published in the medical journal, also featured in some comprehensive journals or other related disciplines journals, dispersed to form special literature. Therefore, many medical journals by subject or album published in journal form, namely one to several, even dozens of articles focus on a topic. For example: a comprehensive journal, "Japan I clinical", college journals, "Department of internal medicine", even professional named after an illness very strong journal, "hypertension", the album form of publishing. (4) knowledge accelerated aging, literature life (half life) shortened. Because of the rapid development of science and technology, the production of new knowledge is accelerating, the existing knowledge more quickly by new knowledge out of life, literature must be shortened. Thus, shorten the publication cycle, grasp the latest literature become the pace with the times and the urgent requirement of knowledge updating, and the fundamental reason to advocate continuing education, lifelong learning and learning society. (5) communication speed. The form of letters, journals, exchange information, to carry out academic exchanges. Now, the editing, publishing, distribution and a series of links with the help of network, whether it is Email, or access to electronic journals, the dissemination of information is the lift a finger in the twinkling of an eye, greatly promoted the rapid communication of information.
