The so-called information consciousness is the intrinsic motivation for people to use information systems to obtain the information they need, which is embodied in a series of thinking processes such as sensitivity to information, selection ability and digestion and absorption ability, so as to judge whether information can be used by themselves or a certain group and whether it can solve a specific problem in real life practice. Information consciousness includes three levels: information cognition, information emotion and information behavior tendency.
The word information literacy was first put forward by Paul Zurkowski, president of American Information Industry Association, in his report to the US government in 1974. He believes that information literacy is people's ability to use information, learn information technology and use information to solve problems at work.
2. The basis of information retrieval-information source
Definition of information source: in the literature terminology published by UNESCO, information source is defined as the source of information obtained by individuals to meet their information needs, which is called information source.
Information source type:
According to the expression, it can be divided into oral information sources, body language information sources, body information sources and literature information sources.
According to the form of digital records, it can be divided into bibliographic information sources, general book information sources, reference book information sources, newspapers, periodicals information sources, special literature information sources, digital library information sources and search engine information sources.
According to the document carrier, it can be divided into printing type, miniature type, machine-readable type and audio-visual type.
According to the document content and processing degree-primary information, secondary information and tertiary information.
According to the publishing form, it is divided into books, newspapers, research reports, conference information, patent information, statistical data, government publications, archives, dissertations and standard information (they are considered as the top ten information sources, and the last eight are called special documents. Educational information resources are mainly distributed in educational books, professional journals, dissertations and other different types of publications)
3. The core of information retrieval-information acquisition ability
1. Learn about various sources of information.
2. Master the retrieval language
3. Skillful use of retrieval tools
4. Be able to judge and evaluate the retrieval effect.
Two indexes to judge the retrieval effect:
Recall rate = amount of relevant information detected/total amount of relevant information (%)
Accuracy rate = relevant information detected/total information detected (%)
4. The key to information retrieval: information utilization
The process of social progress is the process of continuous production, circulation and reproduction of knowledge.
In order to make full use of the existing knowledge and information, we have made great efforts in study, scientific research and health education.
In the process of life, the proportion of information retrieval time is gradually increasing.
The ultimate goal of obtaining academic information is to reorganize all kinds of information and create new knowledge and information by sorting, analyzing, summarizing and summarizing the obtained information, so as to achieve the purpose of activating and adding value to information.
