Reshaping Smart Cities through NGSI-LD Enrichment.

The vast amount of information stemming from the deployment of the Internet of Things and open data portals is poised to provide significant benefits for both the private and public sectors, such as the development of value-added services or an increase in the efficiency of public services. This is further enhanced due to the potential of semantic information models such as NGSI-LD, which enable the enrichment and linkage of semantic data, strengthened by the contextual information present by definition. In this scenario, advanced data processing techniques need to be defined and developed for the processing of harmonised datasets and data streams. Our work is based on a structured approach that leverages the principles of linked-data modelling and semantics, as well as a data enrichment toolchain framework developed around NGSI-LD. Within this framework, we reveal the potential for enrichment and linkage techniques to reshape how data are exploited in smart cities, with a particular focus on citizen-centred initiatives. Moreover, we showcase the effectiveness of these data processing techniques through specific examples of entity transformations. The findings, which focus on improving data comprehension and bolstering smart city advancements, set the stage for the future exploration and refinement of the symbiosis between semantic data and smart city ecosystems.

Applying the Theory of Recreation Specialization to Better Understand Recreationists’ Preferences for Value-Added Service Development

This study examined recreationists’ preferences for the development of value-added recreation products and services using the theory of recreation specialization. A choice modeling method was employed to evaluate the value-added products and services in the for-hire fishing boat industry. Data were collected through a mail survey using Florida saltwater fishing license holders as a study population. Study results indicated that anglers were interested in experiencing new attributes of boat fishing trips besides traditionally fishing-oriented aspects. Further, the results also provided evidence that heterogeneous preferences existed by level of recreation specialization. Study findings generally supported the proposition that as anglers become more involved in fishing activity, their focus expands from activity-specific to activity-general fishing experiences; thus, high specialization anglers likely attach high importance to nonfishing attributes. Managerial implications pertaining to the development of effective recreation products and services are discussed.
