“…They consist of the union of the function and some lexical forms. The starting point for the collection of these dependency patterns was the analysis of the patterns collected for other purposes, i.e., to automatically catalogue risk assessment methods from scientific papers [30] and to extract functions and application fields from patents [3]. In this work, a new analysis was carried out ad hoc to confirm the validity of the dependency patterns retrieved from the literature, through the following procedure.…”

This study proposes some rules for performing a function-oriented search (providing function and object) to extract technical systems from patents, using syntax and dependency patterns to analyse multiple sentences. Unlike the most common inter-sentence analysis methods, the proposed method does not use context information or distance to link the elements of several sentences, but generic terms from patent ontology. The content provided by the rules was entirely derived from a statistical analysis of many patents from different domains, in order to provide a general validity for the rules. The application of the method in two case studies, related to metal cutting and manure processing, highlighted its main advantages. Its degree of automation is such that the expert is almost exclusively excluded, except in the definition of the function on which to build the document pool. The precision and the recall of the results during the tests exceeded 90%. The current limitation concerns the manual control of some results, about 25%, which derive from an additional set of dependency patterns that are difficult to automate and deserve further investigation. The technical systems are many more in number and are more detailed with regard to structural aspects than those obtainable by analysing only single sentences and/or syntax.

“…The bulk of African countries lacks accurate comprehensive data for the several steps highlighted in the framework. This points to the need for comprehensive research to generate the critical data and the knowledge useful to implement the circular bioeconomy should be integrated using text mining based on automatic systems to retrieve information (Spreafico and Spreafico, 2021). Yet Africa still has low research capacity in circular bioeconomy, and severe lack of research infrastructure and funding.…”

“…Munaro and Tavares (2021) noted that material passports and government incentives such as subsidies were crucial in leading the construction industry to embrace circular practices. Other barriers include lack of collaboration among stakeholders, limited technology adoption, archaic building codes and unclear financial benefits (Vincevica-Gaile et al, 2021;Mhatre et al, 2021;Hart et al, 2019; Shaping circular economy Antwi-Afari et al, 2021;Çetin et al, 2021;Zami, 2020;Spreafico and Spreafico, 2021). On the other hand, construction professionals such as architects, engineers and quantity surveyors have a large role to play (Al Hosni et al, 2020;Minunno et al, 2020).…”

Purpose This paper aims to explore the intellectual structure shaping the circular economy (CE) discourse within the built environment in Africa. Design/methodology/approach The study adopted a bibliometric analysis approach to explore the intellectual structure of CE in the built environment in Africa. The authors collected 31 papers published between 2005 and 2021 from the Scopus database and used VOSviewer for data analysis. Findings The findings show that there are six clusters shaping the intellectual structure: demolition, material recovery and reuse; waste as a resource; cellulose and agro-based materials; resilience and low-carbon footprint; recycling materials; and the fourth industrial revolution. The two most cited scholars had three publications each, while the top journal was Resources, Conservation and Recycling. The dominant concepts included CE, sustainability, alternative materials, waste management, lifecycle, demolition and climate change. The study concludes that there is low CE research output in Africa, which implies that the concept is either novel or facing resistance. Research limitations/implications The data were drawn from one database, Scopus; hence, adoption of alternative databases such as Web of Science, Google Scholar and Dimensions could potentially have yielded a higher number of articles for analysis which potentially would result in different conclusions on the subject understudy. Originality/value This study made a significant contribution by articulating the CE intellectual structure in the built environment, identified prominent scholars and academic platforms responsible for promoting circularity in Africa.
