Among the most famous web-based literature databases (including Google scholar, Web of Science (WOS), Scopus, PubMed), WOS (Thomson Reuters) was one of the most frequently used databases for scientific journals within natural sciences in recent years.6 The Web of Science Core Collection includes several Citation Indexes, including Science Citation Index (SCI), Social Sciences Citation Index (SSCI), Arts and Humanities Citation Indexes (AHCI).7 Despite the continual emergence of bibliometric databases in recent years, the Science Citation Index (SCI) is arguably the most reliable index for documenting scientific output.8
The data were obtained from the SCI database published by and subscribed from the ISI, Web of Science (now Thomson Scientific) Core Collection. While WOS guarantees a relatively stable search environment, with clearly defined lists of indexed journals, its searching conditions are restricted to metadata, such as title, keywords and abstracts.9 In order to get full and accurate texts, we narrowed down the literature queries through setting four parameters.
The first parameter is research topic. In advanced search, the "Topic" field tag was set as "TS=(((flood near (event or hazard or disaster)) or (flood near/3 (inundation or damage or risk or zone))) not (volcano or basalt))", where 'near/n' was used to find records containing all terms within a certain number of words (n) of each other. Considering volcano and basalt research is often published as flood papers, 'not (volcano or basalt)' was added to the searching formula to exclude relevant records.
The second parameter is time span. A time span was set to restrict the search results published during the period from January 2000 to December 2017.
The third parameter is publication type. "Article" was selected as the only publication type of this search. This is because other publication types (e.g., discussion, biographical item, editorial material) do not provide sufficient attribute information and are hence not very suitable for our discovery process.
The last parameter is additional citation indexes, Science Citation Index Expanded (SCIE) was added.
In order to get a full description of the papers, full records and cited references were downloaded in .txt format. Description fields include abstract, authors, country, publication year, institution, research area, web of science category, journal, title, source et al. See Figure 1 for more details.
