Data collection method_
| Retrieval database: | Web of Science Core Collection |
| Retrieval mode: | Advanced search |
| Boolean Logic model: | TS= e-government |
| Retrieval time span: | 1900–2020 |
| Citation index: | SSCI; A&HCI; CPCI-SSH; BKCI-SSH; ESCI |
| Languages: | All |
| Type of document: | Article and review |
| Data updated to | February 2020 |
Steps of bibliometric analysis_
| 1. | Gather information from the Web of Science database. |
| 2. | Pre-processing. Unify elements and clean the database. Part of the process consists of unifying duplicates, authority control, set periods of analysis. Not all software allows you to do this pre-processing of the data. It would need several iterations of searches in WoS with Boolean operators to reduce the search to specific articles on the topic. |
| 3. | Choose normalization and visualization measure: In Scimat the Equivalence index is used by the software's author recommendation. In Citespace, we used Cosine as link strength as a default setting. In VOSViewer we used total link strength because it depicts better the relevancy of the units studied for our research purposes. |
| 4. | Extraction of the specific network (co-occurrence of words, authors, countries, organizations; bibliographic coupling of authors references; co-citation of authors and reviews) |
| 5. | Analysis and interpretation of data: discover thematic network and evolution of term over the time. |
