We suggest that you make personalized choices according to your own characteristics.
Description of the library: there are two dimensions in the classification of the operation interface: one is to classify newspapers, doctoral dissertations, periodicals, etc. according to the carrier form of literature sources; Secondly, according to the field of literature, it is divided into education, architecture, medical care and so on.
Generally speaking, the mainstream carrier, such as periodicals, is selected first, and then the literature field to be retrieved is selected.
2: Retrieve parameter settings. In the upper part of the operation interface, there is a search parameter setting dialog box. We'd better fill them out one by one. (1) search term, documents are coded by the system, and each document has a one-to-one code, and a code is a search term. Click the down arrow on the right side of the search item box to pop up all the search items, just select one. (2) Search terms, fill in the content that you request the system to search. There are no clear and strict requirements, not necessarily words. But you need to consider that it should be consistent with the search term you choose. If you use "keywords" in search terms, you can't use long sentences as search terms. (3) Time selection of the document: click the small triangle on the right side of the dialog box to select according to the possible age of the document. It should be noted that the establishment time of China HowNet is 1994, so the data after 1994 is the most comprehensive. Now they are gradually supplementing the literature before 1994, but it may be less comprehensive. (4) Sorting, which prompts the system to present the found documents in what order. (5) Matching, that is, what kind of accurate retrieval is required by the system according to your retrieval requirements. If you are sure of your literature parameters, then choose "accurate", if not, choose "fuzzy".
Parameter setting can make the system find the most suitable literature data according to its own expectations, and can narrow the search range of the system and save time.
3: Click "Search" to complete the first stage operation. Then enter the retrieval results presentation interface: China HowNet 2.rar (click to open and view), and China HowNet results presentation table, explaining the basic information of the literature: literature name, literature carrier, publication time, and collection name in China HowNet.
If we can easily find the literature we want to read from the results of the sixth step, we can stop. However, if it is not easy to see, it is necessary to put forward stricter requirements: divide the species of the document on the left side of the result presentation interface, select only the possible species of the document, then set the retrieval parameters, and then search.
5. If we still can't find the desired literature easily, then we can make multiple progressive searches in the result presentation interface. In the existing search results interface, change and set the search parameters, then select "Search in Results" and search again.
Generally speaking, after completing these steps, you can find relevant literature.
