Explanation of terms related to bibliography , index and abstract in information retrieval tool

List 1 of the book 2 is used for the difference early.

2.Characteristics: Excellent numbers can reflect the overview of a certain academic field in a certain period of time, and have important reference value; The bibliography conveys bibliographic information, reports more comprehensive research results, introduces the content of the book, reflects the publication and collection situation, and provides reference books for circulation and storage; The number indicates the way to read, and also indicates which books need to be read first, which ones need to be read later, those that need to be read carefully, and which ones need to be browsed in general.

Index 1Concept: The index is a reference book that reveals the source of the content of the literature, provides clues for literature search, and arranges the items with retrieval significance (which can be personal names, place names, words, concepts, or other matters) in the literature in an orderly manner for retrieval.

3.Function: Reveal the content of the literature and guide readers to find information, and provide clue guidance for people to obtain literature accurately and quickly.

The index reveals the basic information of a book or periodical, such as articles and sentences. It can provide readers with in-depth, complete, detailed and systematic specific clues of the required literature.

Abstract. 1.Concept: The entries (including the bibliographic part) that describe the content characteristics of a document (abstract) in a search journal are the result of a bibliographic description. Specifically, an abstract is a semantically coherent short text that concisely and accurately describes the important content of the original document.

2.Features: A brief and precise description of the main content of the literature, generally without commentary, supplementation or explanation, between 200 and 800 words in length, with an abstract search tool.

Abstract entries usually consist of a bibliography (title, author, journal name, publication year, volume, issue, page number, language), abstract body, and supplementary items (references, illustrations, number of **, abstract clerk's name, etc.).

This is an excerpt of my understanding (encyclopedia), I don't know if it will be useful to you.

In the process of retrieving literature, readers often encounter the concepts of table of contents, bibliographies, indexes, and abstracts, and what their meanings are and what characteristics they have, which readers often do not understand. Here are some explanations of these concepts, I hope it will be helpful to readers.

1) Table of Contents. A catalogue is a tool for revealing and reporting a group of relevant documents and arranging them in a certain order. Table of contents is also known as bibliography. It describes the literature relatively simply, and the bibliographic items of each entry include the book (journal title), the number of volumes (issues), the author, the date of publication, the place of publication, and the collection of books (periodicals).

There are many types of catalogs, including national bibliographies, collection catalogs, joint catalogs, etc.

2) Bibliography. Bibliography is a tool for arranging the most important items in books and newspapers according to a certain sorting method for people to find the source of the articles. The bibliographic items of the bibliography usually include: the title, the author (or including his affiliation) and ** source, without a summary.

3) Indexing. The index is a retrieval tool that compiles the titles, words, topics and other items discussed in the content of books and periodicals according to a certain ranking method, indicates the source, and is used by readers to check and use. An index is a revelation of the deeper content of the literature.

The fundamental difference between the index and the table of contents is that the object of the description is different, the catalog records a complete publishing unit, such as a book, a periodical, etc., while the index records a certain part of a complete publication, a certain point of view, a certain knowledge unit, therefore, the index can solve the lack of the catalog only for the overall macro description of the literature, meet the reader's requirements for the micro disclosure and retrieval of the literature content unit, and improve the depth and retrieval efficiency of the literature retrieval.

Common indexes include Science Citation Index, Chinese Social Science Citation Index, Thirteen Classics Index, Twenty-four Historical Records Names Index, Chinese Philosophy History ** Index, Poetry Classics Index, Historical Records Index, etc.

4) Digest. Abstract is a retrieval tool that reports literature by describing the external characteristics of the literature and concisely extracting the main points of the literature, which is the core of secondary literature. It is characterized by the addition of abstracts that indicate the content characteristics of the literature, and the important contents, academic views, data and structures of the literature are accurately extracted in concise language, and arranged according to certain bibliographic rules and arrangements for readers' reference.

The literature reported in the table of contents, bibliographies, indexes, and abstracts is relatively short and spans a long era, which can help us understand the origin, changes and latest progress of a certain discipline, and facilitate the grasp of the whole discipline, which will be of great help to us to consult the literature.

It can be divided into the following types:

1. Catalog-type search tool.

A catalog-based search tool is a tool that records specific publishing units, collection units, and other external characteristics. It takes a complete publishing or collection unit as the bibliographic unit, and generally records the name, author, and source of the document. There are many types of catalogs, and for literature search, national bibliographies, joint catalogs, and collection catalogs are particularly important.

2. Bibliographic retrieval tool.

The bibliographic retrieval tool is a type of retrieval tool that uses a single document as the basic bibliographic unit to describe the appearance characteristics of a document (such as the title of the document, the name of the author, the source of the document, etc.), without the content of the abstract, and is a kind of retrieval tool that quickly reports the information of the document.

3. Abstract retrieval tools.

Abstract retrieval tool is a retrieval tool that selects a large number of scattered documents, selects important parts, makes abstracts in a concise form, and organizes and arranges them according to a certain method. According to the compiler of the abstract, it can be divided into author's abstract and non-author's abstract.

4. Index-based search tools.

The indexed retrieval tool is a retrieval tool that arranges the relevant items or knowledge units in certain important documents within a specific range, such as book titles, journal titles, personal names, place names, and words, according to certain needs, and indicates the source, so as to provide users with literature clues.

According to the different bibliographic formats, information retrieval tools can be divided into the following types:

1. Table of contents: A description of the appearance characteristics of books or publications.

2. Index: A tool that describes the external or internal characteristics of information (such as title, author, subject, classification, etc.) in various search languages, and organizes them according to a certain method, so that users can further find the original information content according to the clues of the investigation.

3. Abstract retrieval tool: Abstract is generally composed of two parts: bibliography and content abstract, which is the main retrieval tool for systematically reporting, accumulating and retrieving information, and is also the core of traditional retrieval tools.

Table of Contents, Bibliographies, Indexes, Abstracts.

A citation index is a way to search for documents by using the cross-citation relationship between them. After finding out a batch of required documents from the citation index, and then using the citations of these documents to find a batch of new documents, this can not only obtain a certain number of relevant literature, but also reveal the influence of old literature on new literature, the evaluation of new literature on old literature, and show the relationship between new and old literature in academic research.

The citation index covers the literature of various disciplines, so that it can reveal the intersection of disciplines from different perspectives.

and interpenetration, which is an effective way to provide research results of marginal disciplines;

Improve search efficiency. As long as you have a document that has been cited many times, you can find the ** literature with related content in a very short time, which is faster than regular indexing.

According to the frequency of citation, combined with other methods, it can provide an objective basis for evaluating the academic level and social impact of a certain **, a certain journal and a certain author.

The citation index is mainly composed of a "citation index", a "corporate index", a "source index", and a "permuterm subject index" (psi) that selects several keywords from the name of the document at a time and sorts them by the method.

Answer: Features: Abstract retrieval tool is a retrieval tool that selects a large number of scattered documents, selects important parts, makes abstracts in a concise form, and organizes and arranges them according to a certain method.

According to the compiler of the abstract, it can be divided into author's abstract and non-author's abstract. Author's digest refers to an abstract written by the author of the original text; Non-author's abstracts are those written by specialized abstract staff who are familiar with the profession. In terms of the degree of detail of the abstract, it can be divided into two types: indicative abstracts and reportage abstracts.

The indicative abstract states the title, content scope, research purpose and source of the literature in the shortest language, which is actually a supplementary description of the title, generally about 100 words; The purpose of the reportage abstract is to reveal the essence of the topic discussed in the original text, which basically reflects the content of the original text, the scope and purpose of the discussion, the research means and methods adopted, the results or conclusions obtained, and also includes relevant data, formulas, and general e-line diagrams. About 500 words, important articles can be as many as 1,000 words.

The importance of abstract-based search tools mainly includes: clear purpose and clear professional scope; A large amount of literature is included in the same major; The retrieval function is powerful, and the missed detection rate is low; It can be linked to different full-text databases, saving time, etc.

1.Describe in detail the content characteristics and appearance characteristics of the literature; 2.Each document record must have a search mark; 3.Literature entries form an organic whole in a certain order; It can provide a variety of search methods.

Program index abstracts are secondary literature.

1 Primary document: that is, the original document, usually refers to the original creation of the author. The content of this kind of literature record is specific, systematic, detailed, innovative, and creative, and is the main focus of literature retrieval.

Monographs, journals**, degrees**, research reports, conferences**, patent specifications, etc. are all primary literature.

Because it provides clues and convenience for finding and using primary literature, it is regarded as the main tool and means for literature search. Bibliographies, catalogs, indexes, abstracts, etc. belong to the secondary literary conquest.

Bibliographic information retrieval is a method of retrieving or obtaining information from a variety of bibliographic catalogs using computer technology.

Bibliographic information retrieval refers to the retrieval method in which users can limit some specific numerical information in the literature by setting query conditions, such as year, quantity, **, etc., to obtain the literature records associated with the required information in the process of literature information retrieval. This method is fast, simple and efficient.

The core meaning of bibliographic information retrieval is filtering and screening. A large amount of literature information is deleted according to the numerical conditions set by the user, and the search results that meet the requirements are selected to achieve efficient retrieval. In addition, bibliographic information retrieval also includes the processing of the logical relationship of search terms, such as and, or, not, etc.

The advantage of bibliographic information retrieval is that it can help users quickly and accurately locate the required documents, especially in today's massive amount of information, bibliographic information retrieval has become an indispensable and important tool for scientific research and academic workers. At the same time, bibliographic information retrieval can also improve the retrieval speed, improve work efficiency, and save time and energy.

Description of the database for bibliographic information retrieval:

Bibliographic database of general Chinese books after the year.

It includes more than 300,000 bibliographic data of Chinese general books published after 2001 in the Capital Library. It also includes a small number of bibliographic data for books published before 2001. The books in the database are classified by the Chinese Library Book Classification Law.

Bibliographic database of common Chinese books years ago.

The database includes more than 330,000 bibliographic data of Chinese general books published from 1975 to 2001 in the Capital Library. It also includes some bibliographic data for books published after 2001 and a small amount before 1975. The books in this database are classified according to the Chinese Library Book Classification Method.

1975 General Chinese Bibliographic Database.

The database includes more than 120,000 bibliographic data of Chinese general books published from 1949 to 1975 in the collection of Liang Xiao of the Capital Library. It also includes a small amount of bibliographic data for books published after 1975. The books in this database are classified according to the Chinese Library Book Classification Method.

The search method of using the title of the book, journal or article as the search term is the nomination method.

The key to the classification of literature search is to correctly understand the classification table of the search tool and divide the items to be checked into the corresponding category and report. Some search tools, such as the Chinese Science and Technology Data Catalogue, are arranged by category and can be searched according to category.

Classification pathways. The classification approach refers to the way to search according to the category of the discipline (major) to which the literature belongs, and it is based on the classification index in the search tool.

Thematic pathways. The subject approach refers to the way to search through the content subject of the document, which is based on various subject indexes or keyword indexes, and searchers can carry out the search as long as they determine the search terms (subject headings or keywords) according to the project.

The key to literature retrieval is to analyze the project, refine the topic concept, and use words to express the topic concept. The subject route is one of the main search routes.

Author's Pathway. The author's route refers to the way to search for documents according to the known authors of the literature, which is based on the author's index, including the individual author's index and the organization's index.

Title pathway. It refers to the way to find a document by its title. The title includes the title of the document, the title of the book, the issue number, the standard number, the database name, etc., and the search can be carried out by using the title index, journal title index, conference ** index, etc. of the search tool.

The functions of the search pathway include:

4. Improve the quality of information retrieval: Different retrieval methods may adopt different algorithms and strategies to rank and filter the same query results and improve the quality of information retrieval.

5. It is convenient for users to choose the best information source: By comparing the type and quality of information provided by different search channels, users can choose the information source that best meets their needs.
