Keyword selection experience and skills analysis

When we use a search engine to search for materials, the key to selecting keywords is beyond doubt. Correct analysis and processing of keywords is an essential prerequisite for improving search result satisfaction. At the same time, new problems will emerge in the search practice, and New Keyword selection principles and more experience and skills will emerge. Learning the common knowledge of keyword Analysis and Processing also deepens our understanding of search engines.

 

1. Master the selection principles of keywords

The quality of search results is closely related to the selection of keywords. You can choose the appropriate keywords from the following points.

(1) accuracy. Accurate keyword expression is a prerequisite for obtaining good search results. To improve the accuracy of keywords, you need to pay attention to two aspects: first, avoid typos; second, avoid ambiguous words and words. For keywords that are simple, common, and prone to ambiguity, some restrictive modifiers should be added to provide a complete description of the search purpose. For example, if you change "apple" to "fruit Apple", the search results will become much satisfied. In addition, the use of search syntax combinations of keywords can also effectively improve the search quality, such as "dietary nutrition science", using English double quotes to make long keywords as an integral whole, to improve the accuracy of the search results. Most of the search syntax is simple. before using the search engine, you can spend a little time learning its syntax rules, which helps you quickly and efficiently find the required information.

(2) strive to be concise. Currently, search engines are not very powerful in processing natural languages. Therefore, when submitting a search request, you 'd better extract your thoughts into simple query words that are associated with the topic of the information you want to find. For example, in the previous example, "first-year students' famous saying about patriotism", if you delete the "first-year students" that do not affect the search results, you can discard the redundant "about ", remove the "Celebrities" with repeated meanings and extract them into concise "Patriotic quotes ". In this way, starting from the search intent, you can select and extract the topic information of the search term to form a clear and accurate concept, so as to avoid retrieval failure due to lengthy search term.

(3) representative. That is to say, keywords must be a typical indicator of the queried things. Time, character, and location can generally be an effective limiting factor for adding representativeness of keywords. For example, if you search for the syllabus of the professional title foreign language examination and set the keyword as "Outline of the professional title foreign language examination", Baidu search engine will search for 120,000 pieces of information. If you add the Time Limit word "2007", add a region limit word "China", and add a special restriction word "professional technician ", finally, I changed the keyword to "Outline of the foreign language examination for professional and technical personnel in China in 2007", and only 940 articles were found in Baidu's search results. Therefore, the most representative and indicative keywords are crucial to improving search efficiency.

 

2. Learn some key word selection skills

(1) high-frequency lexical. A successful search usually consists of several searches. Generally, a simple keyword is used to perform a tentative search. Then, you can analyze the information you need and pick out frequently-occurring words, design a better keyword expression to search for these high-frequency words together with the original keyword, and then search for more satisfactory results.

(2) Use related searches ". Related searches refer to a series of query words that are near-semantic, synonymous, or very similar to your search keywords. For example, if you enter "dietary nutrition science" in the search box, the following search is displayed on the bottom of the baidu search page: "nutritional diet", "dietary nutrition and health", "diet and nutrition", "dietary nutrition and health paper", "Food and Nutrition Teaching Plan", "children's nutritional diet"," "nutritional diet for children", "dietary nutrition", "nutritional diet for pregnant women", and "more related searches ". These related query words are generally commonly used and more likely to produce relevant results, which are arranged at the bottom of the search result page according to the search popularity. If you are not satisfied with the search results because the keywords you typed are not appropriate, you can refer to "related search" for some inspiration, you can also click a related search item to obtain the result page.

(3) flexible use of search syntax. Compared with other computer languages, the search syntax is quite easy to learn. The flexible use of keywords in combination with the search syntax will greatly improve our search efficiency and search accuracy. For example, I want to download the "Ninth set of broadcast gymnastics" file on the website of Jimei University, and add "site: site domain name" after the content to be queried ", restrict the search scope to a specific Jimei University site. Therefore, enter "Guilin website construction site: www.the054.com" in the search box. In this way, relevant information is found very quickly and accurately.

(4) select keywords Based on Web features. Many types of web pages have similar features. For example, a novel webpage usually has a directory page, which usually contains the word "directory". When querying a novel, you can add the word "directory" to the keyword; for another example, on the software download page, there is usually a download link in the webpage body and the word "Download" appears. If you want to download a software, add "Download" to the keywords to improve the accuracy of the search results.

In short, when using a search engine, selecting keywords is an accumulation of experience. Through continuous practice, you can learn and get used to using multiple keywords to develop a good and effective search habit, and pay attention to observation, summary, and improvement will make the search more accurate and efficient.
