Abstract:

Based on the Web of Science core collection database, the study used the R-bibliometrix package for literature biliometric analysis such as keyword co-occurrence analysis, co-word analysis and high cited publications analysis taking soil ammonia volatilization as an example, and explored a practical method of literature retrieval by using literature biliometric analysis so as to quickly find key literatures that are closely related to research topics in a huge literature database. The results showed the number of retrieved literatures was 3573 (a large number) and the majority of the Top 10 highly cited publications had little to do with soil ammonia volatilization after first literature retrieval via entering a few easy-to-think keywords like soil ammonia volatilization. Then the first retrieved literature data was biliometric analyzed to get keyword co-occurrence network map, keywords conceptual structure map and Top 10 highly cited publications. According to the above-mentioned results, we screened and eliminated the inconsequential keywords, and then refined search for the second literature retrieval. After performing the process twice, the number of retrieved literatures had dropped to 160, among which the Top 10 highly cited publications were closely related to the research topic. And then we hypothesized that the key literatures about the relationships between soil NH3 volatilization and water, temperature, management needed to be accurately retrieved. The results by using the above-mentioned method demonstrated that only 26, 20, and 28 related literatures were retrieved, respectively. Therefore, the feasibility of the method was verified. Consequently, the method of literature retrieval by using literature biliometric analysis is feasible to accurately retrieve key literatures. Furthermore, the method of literature retrieval by using R-biliometrix tool based on big data could help researchers retrieve key literatures, find scientific gaps, determine scientific problems, and obtain scientific research ideas and solutions.
