Contents, titles, abstracts and indexes belong to secondary literature.
Monographs, reviews, encyclopedias, standard documents and product samples belong to three kinds of documents. The comprehensive articles in periodical papers and conference papers belong to three times. A small part of the paper is a comprehensive paper, which also belongs to three documents.
Question 2: How many documents do the following belong to? Dissertations, scientific reports and patent documents are first-class documents; Most periodical papers and conference papers belong to one document.
Contents, titles, abstracts and indexes belong to secondary literature.
Monographs, reviews, encyclopedias, standard documents and product samples belong to three kinds of documents. The comprehensive articles in periodical papers and conference papers belong to three times. A small part of the paper is a comprehensive paper, which also belongs to three documents.
Question 3: What types of documents are included in Level 2 and Level 3 documents? Are carriers of recording knowledge. Specifically, literature is a combination of words, symbols, images, audio and so on that record knowledge and information on a certain material carrier. From this definition, we can see that literature has three basic attributes, namely, knowledge, record and materiality. It has the functions of storing knowledge, transmitting and exchanging information. Because there are many kinds of documents, each has its own characteristics, and the information content recorded by different types of documents also has its own emphasis, therefore, it will be of great help to further do a good job in document retrieval to understand the levels, types and characteristics of documents first. According to the difference of knowledge transfer, information quality and quantity and processing level, documents are divided into four levels, which are called zero documents, first-class documents, second-class documents and third-class documents. 1 .0 document This is a special form of information source, which mainly includes two aspects: one is the knowledge information before the document is formed, that is, it is the oral conversation of people and the non-document information that directly acts on people's sensory organs; Second, the original documents that have not been publicly published in the society, or various books and periodicals that have not been officially published, such as letters, manuscripts, records, notes, etc., also include some books and periodicals that are used internally and cannot be obtained through public formal ordering. Zero-order documents are generally obtained by oral conversation, visiting exhibitions and attending reports, which not only has certain value in content, but also can make up for the time-consuming shortcomings of general public documents from the objective formation of information to public dissemination. 2. Documents This is a document produced by people directly according to their practical experience in production, scientific research and social activities. It is also often called the original document (or a kind of document), and its recorded knowledge and information are novel, specific and detailed. Primary literature is the largest, most diverse, most widely used and most influential literature in the whole literature system, such as periodical papers, patent documents, sci-tech newspaper nails, conference proceedings, dissertations and so on. These documents are innovative, practical and academic, which are the main basis for comparative analysis of documents in sci-tech novelty retrieval. 3. Second-level documents Second-level documents, also known as second-level documents, sort out, concentrate and refine a large number of scattered and disorderly first-level documents, arrange and store them according to a certain logical order and scientific system, and systematize them for retrieval and utilization. Its main types are catalog, index and abstract. The secondary literature is obviously collectible, systematic and retrievable. It collects not the original literature itself, but the clues of the original literature within a specific range. Its importance lies in greatly reducing the time spent searching a document. Secondary literature is the main tool used to retrieve literature in novelty retrieval. 4. Third-level documents Third-level documents, also known as third-level documents, are documents compiled by selecting a large number of related documents through comprehensive analysis and research. Usually, it is formed by collecting a large number of relevant documents around a certain topic through secondary literature retrieval and deeply processing its contents. There are reviews, comments, comments, progress, trends and so on. These documents comment, summarize and predict the development trend of existing achievements, which has high practical value. In the novelty retrieval work, we can make full use of the review literature reflecting the research trends in a certain field, and understand its research history, development trends and level in a short time, so as to more accurately grasp the technical background of the items to be retrieved and grasp the novelty retrieval points. In short, from zero-level documents, first-level documents, second-level documents to third-level documents, it is a different level processing process of knowledge information from dispersion to concentration, from disorder to order, and from erudition to refinement. The quality and quantity of information they contain are different, and they play different roles in improving people's knowledge structure. The zero-level and first-level documents are the most basic information sources and the main objects of document information retrieval and utilization; Secondary literature is a centralized refining and sorting of literature and a tool for literature information retrieval; The three documents are the results of comprehensive analysis and processing of scattered zero documents, first-level documents and second-level documents according to the categories of topics or knowledge. They are highly concentrated literature information, which is not only the object of literature information retrieval and utilization, but also the tool of literature information retrieval.
Question 4: What are primary documents, secondary documents, tertiary documents and primary documents? This is a document produced by people directly according to their practical experience in production, scientific research and social activities. Also often referred to as original documents (or first-class documents), the knowledge and information recorded in them are novel, specific and detailed. Primary literature is the largest, most diverse, most widely used and most influential literature in the whole literature system, such as periodical papers, patent documents, scientific reports, conference proceedings, dissertations and so on. These documents are innovative, practical and academic, which are the main basis for comparative analysis of documents in sci-tech novelty retrieval.
Secondary literature, also known as secondary literature, is to sort out, concentrate and refine a large number of scattered and disorderly primary documents, arrange and store them according to a certain logical order and scientific system, and systematize them for retrieval and utilization. Its main types are catalog, index and abstract. The secondary literature is obviously collectible, systematic and retrievable. It collects not the original literature itself, but the clues of the original literature within a specific range. Its importance lies in greatly reducing the time spent searching a document. Secondary literature is the main tool used to retrieve literature in novelty retrieval.
Third-level literature, also known as third-level literature, is a literature compiled by selecting a large number of related documents through comprehensive analysis and research. Usually, it is formed by collecting a large number of relevant documents around a certain topic through secondary literature retrieval and deeply processing its contents. There are reviews, comments, comments, progress, trends and so on. These documents comment, summarize and predict the development trend of existing achievements, which has high practical value. In the novelty retrieval work, we can make full use of the review literature reflecting the research trends in a certain field, and understand its research history, development trends and level in a short time, so as to more accurately grasp the technical background of the items to be retrieved and grasp the novelty retrieval points.
Question 5: What are the manifestations of third-level documents such as statistical yearbook? The third-level literature is the literature sorted out from the second-level literature.
Question 6: What is the difference between first-class literature, second-class literature and third-class literature? According to the content, nature and processing methods of literature, literature can be divided into primary literature, secondary literature and tertiary literature. Primary literature refers to the original literature created on the basis of the author's own research results, such as periodical papers, research reports, patent specifications, conference papers, etc. Secondary literature is one of the retrieval tools such as bibliography, title record, introduction and abstract. The three documents are based on the first-level documents and the second-level documents. People usually refer to these documents as the results of "information research", such as reviews, thematic reviews, annual summaries of disciplines, progress reports, data manuals and so on. Similarly, some people divide intelligence into primary intelligence, secondary intelligence and tertiary intelligence.
Question 7: What are primary documents, secondary documents, tertiary documents and zero documents? The most original literature that has not been published or spread into the society. Such as personal notes, experimental records and other first-class documents: usually refers to the original, that is, the documents created (or written) with the author's own research results as the basic elements, mainly including periodical papers, scientific reports, dissertations and other second-class documents: the products obtained by the document information workers for the purpose of management and utilization, including bibliographies, indexes, abstracts and so on. Three kinds of documents: the results compiled by using the contents of secondary documents and selecting the contents of primary documents, such as dictionaries, handbooks, yearbooks, encyclopedias, monographs, textbooks, essays, summaries, literature guides, bibliographies, etc. The process from primary literature to secondary literature and then to tertiary literature is the process from extensive literature to centralized literature and from disordered literature to systematic literature. It is also the process of document processing depth (hierarchical structure) from disorder to order, and from one orderly structure to another perfect orderly structure.
Question 8: How many documents does the textbook belong to? Textbooks are documents formed by collecting the research results of predecessors and others and after in-depth and meticulous training and processing. It belongs to three documents.
