5.2.3. Semantic Category

The semantic category deals with the dimensions connected with information rather than data. Information is selected data to which meaning has been assigned in a particular context. It is concerned with meaning. Within the semantic category, the dimensions were ranked as ambiguity, definition, believability, interpretability, reliability, understandability, and data validity, as shown in Table 9. The dimension ambiguity was prioritised over other data dimensions within the category. This might be because the data should be clear for understanding if any ambiguity in data can lead to significant challenges in decision-making for highway projects, potentially resulting in poor design, construction, and long-term consequences for the environment and public safety. The Garrett mean values that were calculated using Equation (1) and the percentage position values are shown in Table 5.
