The purpose of this paper is to address the application of knowledge management (KM) in archaeology, an important subdiscipline of the humanities that studies our past through material culture. Archaeologists increasingly deposit documentation and data from their field and laboratory work in digital repositories. Rapidly growing quantities of digital archaeological data require more effective KM methods and applications for their analysis, presentation and interpretation of their meaning to the audience. To demonstrate such benefits of KM, a case study was carried out to examine the application of two specific KM initiatives: network analysis and graphical visualisation in the context of a UNESCO-listed world heritage site (Bosnian medieval necropolises). The assumption was that these two KM initiatives would jointly facilitate the understanding of the cultural heritage of interest by reducing the complexity of the research space from a 1519-page text (archaeological sites description) to a single visual (network graph of archaeological artefacts). A set of 30 nominated necropolises (Nomination 1504, 2016) known as “stecci“ was used as a sample of the medieval Bosnian tombstone graveyards for the current study. Each of these graveyards was described in the following way. Firstly, basic details of the graveyard (name, location, size and number of tombstones) were identified and entered into a spreadsheet file. Secondly, different types of the existing tombstones’ shapes, decorations and inscriptions were extracted from the text. These were added to the spreadsheet file in the form of keywords. Thirdly, the initial metadata were further transformed into nodes and edges of interest for further network analysis. Finally, such transformed digital data were presented visually with graphs. This paper made two important contributions to research. Firstly, it expanded a line of interdisciplinary research started by Handzic and Dizdar (2016) that should benefit both KM and the humanities. It further reinforced the idea that the increased scale of big data might offer new and exciting possibilities and challenges for future scholarship in KM and different arts and sciences. Secondly, the paper provided new positive evidence of the value of KM for the humanistic research agenda. Specifically, in the case of archaeology, the paper showed how network analysis and graphical visualisation of the relationships between medieval graveyard tombstone sites, shapes, decorations and inscriptions could serve as an indicator of the prevailing Bosnian religious, artistic and poetic character during the Middle Ages. This study implies that KM may change the way archaeologists and other humanities scholars interact with their data and share their insights. In particular, the paper suggests that the network analysis and visuals work well together to picture the past. However, these implications need to be interpreted with caution due to a number of limiting factors. Among these are: specific context of medieval Bosnia, small sample size of archaeological sites and artefacts, as well as subjective choice of KM initiatives. Future research is recommended to address these limitations and extend current research to other KM initiatives and their applications in other scholarly disciplines.
