The tourism sector has benefited from the easier access to digital technology and the influx of social media content with Geo-tagging. This study describes a novel approach to offering personalized travel recommendations using geo-tagged images as the basis to recommend specific places for tourism. Unlike traditional approaches that use user reviews or surveys, the system takes advantage of geographic metadata and image recognition. Geo-tagged images are used to identify tourist hotspots and subsequently, spatial patterns are analyzed using effective methods. To balance the popularity of tourist destinations and the density of people in those areas, the system employs min-max normalization and ranking using Haversine Distance to filter and rank tourist locations defined by the user through density preferences. The backend optimization is done on large datasets with time complexities targeted at O(k) through the use of a Python-Flask stack. Results from the first exploratory phases reveal the system’s ability to generate context-sensitive recommendations promptly, which is beneficial to Destination Marketing Organizations (DMO’s) and travel businesses for increasing the precision of promotional campaigns. This study tackles issues of data noise, privacy, lacking temporal data among others, suggesting the incorporation of temporal patterns with real-time feedback to improve the recommendation algorithms. This not only increases the user’s satisfaction by personalizing the experience, but also promotes environmentally sustainable tourism by shifting visitor concentration from popular places to less popular sites.

摘要

The tourism sector has benefited from the easier access to digital technology and the influx of social media content with Geo-tagging. This study describes a novel approach to offering personalized travel recommendations using geo-tagged images as the basis to recommend specific places for tourism. Unlike traditional approaches that use user reviews or surveys, the system takes advantage of geographic metadata and image recognition. Geo-tagged images are used to identify tourist hotspots and subsequently, spatial patterns are analyzed using effective methods. To balance the popularity of tourist destinations and the density of people in those areas, the system employs min-max normalization and ranking using Haversine Distance to filter and rank tourist locations defined by the user through density preferences. The backend optimization is done on large datasets with time complexities targeted at O(k) through the use of a Python-Flask stack. Results from the first exploratory phases reveal the system’s ability to generate context-sensitive recommendations promptly, which is beneficial to Destination Marketing Organizations (DMO’s) and travel businesses for increasing the precision of promotional campaigns. This study tackles issues of data noise, privacy, lacking temporal data among others, suggesting the incorporation of temporal patterns with real-time feedback to improve the recommendation algorithms. This not only increases the user’s satisfaction by personalizing the experience, but also promotes environmentally sustainable tourism by shifting visitor concentration from popular places to less popular sites.
