Article A Systematic Review of Symbolic Aggregate Approximation (SAX)(Ankara University Faculty of Science, 2026) Nalici, Mehmet Eren; Söylemez, İsmet; Ünlü, RamazanTime series data can be analyzed through various techniques to tackle classification or regression tasks. Symbolic Aggregate Approximation (SAX) is one such technique used for time series data reduction that converts the data into a symbolic representation, enabling more efficient storage, retrieval, and analysis by reducing the dimensionality while preserving the essential patterns within the time series. In this paper, we provide a systematic literature review of SAX by examining relevant literature from 2007 to 2025. The review includes 321 articles sourced from the Web of Science (WOS) database. However, the 85 most cited and recently published studies are summarized. Utilizing collaboration network analysis, the study identifies the nations, affiliations, and authors involved in SAX research, as well as their co-authors and commonalities. Additionally, an analysis is conducted to explore the potential relationship between the articles and the United Nations' Sustainable Development Goals. These findings provide insights into the current landscape of SAX research and offer potential avenues for future exploration. By pinpointing research gaps, scholars can use this review to anticipate forthcoming research trajectories.Article Citation - WoS: 20Citation - Scopus: 20Origins, Evolution and Themes of Scholarly Hospitality Sources: 1960-2019(Elsevier Sci Ltd, 2021-04) Koseoglu, Mehmet Ali; Mehraliyev, Fuad; Aladag, Omer Faruk; King, BrianThis paper provides an overview and insight into the intellectual foundations and evolution of hospitality scholarship. The authors found that hospitality research has exhibited certain defining and evolving characteristics when an extended period - six decades - is considered. Quantitative methods have predominated with ongoing efforts to reach agreement about the most valid and applicable research methods. Four of the six identified research domains are marketing related, each with its defining characteristics. Some domains are heavily reliant on sources from work originally published in "mainstream" literature such as marketing, though the fast-developing field of online reviews draws sources overwhelmingly from the hospitality and tourism journals. The paper contributes to theory by synthesizing key theoretical concerns over six decades. It also evidences the shift of hospitality scholarship from its pragmatic and operational origins to a stronger theory base offering practitioners an important reference point when confronting unprecedented industry upheavals.
