Steps to reproduce

To reproduce this study using the "Feature Priorizer" R Markdown tool, researchers should follow these steps: ๐€) ๐ƒ๐š๐ญ๐š ๐‚๐จ๐ฅ๐ฅ๐ž๐œ๐ญ๐ข๐จ๐ง: Use the questionnaire provided in the study to collect responses from laboratories.

In this study, 59 features were created, but additional features may be defined depending on the analytical context. Each feature should be encoded as a binary variable (Yes/No format) following the methodology applied in this study. To enhance interpretability and standardization, we recommend naming each feature using Lexical Blendsโ€”formed by merging parts of two or more wordsโ€”following the approach used in this study. This helps create intuitive and meaningful labels for each feature. ๐‚) ๐ƒ๐š๐ญ๐š๐ฌ๐ž๐ญ ๐…๐จ๐ซ๐ฆ๐š๐ญ๐ญ๐ข๐ง๐  & ๐Ž๐ซ๐ ๐š๐ง๐ข๐ณ๐š๐ญ๐ข๐จ๐ง: Save the dataset as an Excel file (.xlsx format) and place it inside the "1_Dataset" folder.
