4.2 Bibliometric analysis
Biblioshiny (the graphical interface of Bibliometrix) is subdivided in several menu that guides the user throughout the whole process of bibliometric analysis o the dataset. The following section is subdivided just by following the proposed workflow in the software.
4.2.1 Dataset cleaning
During the analysis process, we found several errors in the dataset, so it needs to be cleaned. In brief we summarize here the cleaning process:
- Journal of information technology in construction appears also as Electronic Journal of information technology in construction, by applying "trova-e-stostituisci" in excel, we substitute all the terms in the format " Journal of information technology in construction "
- For 13 documents the author is "NA NA" that stands for Not Available, by looking in excel file we notice that those papers are "conference review" (12) and one (1) "book chapter". These are not research papers but review of conferences and their metadata ar very poor or missing, so we can remove them. We do not delete them, but in the "filter" menu we simply filter them out.
- Most cited papers: SUCCAR, B., BUILDING INFORMATION MODELLING FRAMEWORK: A RESEARCH AND DELIVERY FOUNDATION FOR INDUSTRY STAKEHOLDERS (2009) AUTOMATION IN CONSTRUCTION, 18 (3), PP. 357-375 was written in two different ways, by applying "trova-e-sostituisci" in excel we solved the problem.
- The same problm with GU, N., LONDON, K., UNDERSTANDING AND FACILITATING BIM ADOPTION IN THE AEC INDUSTRY (2010) AUTOMATION IN CONSTRUCTION, 19 (8), PP. 988-999
- Most relevant words: in the "keyword plus"there are those terms "building information model - bim" and "building information modelling" we could merge them in excel, but considering that the keyword plus are standardized, the two terms represent two separate things, so we let them separated.
- A simikar problem was in the "author's keywords", to solve it we merge togheter all the ways they used to write "BIM" (more than 5).
4.2.2 Load
- Loaded files: 564
- Documents type: article, article in press, book, book chapter, conference paper, conference review, review, short survey
4.2.3 Filter
filtered out "conference review" (after filtering: 552 documents)
4.2.4 Dataset
- Sources 249, for 564 documents (of which 256 are articles, 224 are conference papers and 72 are other type)
- Annual scientific production: by looking to the following plot (Fig.1) we can note a pick in our dataset in 2017 that seems to be continuing also in 2018 - with just a small reduction.
