1. What kind of platform is China HowNet?
China HowNet is the largest academic resource pool and one of the comprehensive academic publishing platforms in China. Directed by the Ministry of Education of China and operated by China Institute of Science and Technology Information, it aims to provide users with comprehensive and authoritative academic literature resources and services.
As a comprehensive academic platform, China HowNet provides rich academic resources, including periodical papers, doctoral papers, conference papers, newspapers, yearbooks, standards, patents and other literature types. Among them, periodical paper resources cover important periodicals in various fields, including natural science, engineering technology, medicine and health, social science and other disciplines.
Through China HowNet, users can search, read, download and quote documents. The platform provides a powerful retrieval function, supporting keyword retrieval, author retrieval, periodical retrieval and so on. Users can also obtain the abstracts and full-text contents of the literature through China HowNet, read or download and save them online, and quote the literature as needed.
Second, the method of narrowing the search scope.
1, set the retrieval conditions.
In the search interface, you can set some search conditions to narrow the scope. For example, you can choose a specific literature type (such as journal articles, dissertations, conference papers, etc.). ), limit the time range and select specific authors or institutions.
2. Use advanced retrieval function
China HowNet provides advanced retrieval function, which can further refine the retrieval conditions. Through advanced retrieval, you can combine multiple keywords and use logical operators (such as AND/OR/NOT) to accurately match the document content.
Step 3 use classification labels
The documents of China HowNet usually have corresponding classification labels or indexes, such as domain classification, subject classification, keyword indexing and so on. These tags can be used to narrow the search scope and only obtain relevant documents in the field of interest.
4. Read the abstract of the literature
In the retrieval results, reading the abstract of a document quickly helps to judge whether the document is related to the research topic. Through careful screening of abstract information, we can narrow the scope and obtain more valuable documents.
5. Find relevant literature.
In the search results, you may find some articles that are highly related to the literature you are interested in. By looking at the citations or references of these related documents, we can further acquire and screen more related documents.
