Exploiting a Map-Based Interface in Conversational Recommender Systems for Mobile Travelers

Abstract

Nowadays travel and tourism Web sites store and offer a large volume of travel related information and services. Furthermore, this huge amount of information can be easily accessed using mobile devices, such as a phone with mobile Internet connection capability. However, this information can easily overwhelm a user because of the large number of information items to be shown and the limited screen size in the mobile device. Recommender systems (RSs) are often used in conjunction with Web tools to effectively help users in accessing this overwhelming amount of information. These recommender systems can support the user in making a decision even when specific knowledge necessary to autonomously evaluate the offerings is not available. Recommender systems cope with the information overload problem by providing a user with personalized recommendations (i.e., a well chosen selection of the items contained in the repository), adapting this selection to the user's needs and preferences in a particular usage context. In this chapter, the authors present a recommendation approach integrating a conversational preference acquisition technology based on "critiquing" with map visualization technologies to build a new mapbased conversational mobile RS that can effectively and intuitively support travelers in finding their desired products and services. The results of the authors' real-user study show that integrating map-based visualization and critiquing-based interaction in mobile RSs improves the system's recommendation effectiveness, and increases the user satisfaction.

Harnessing geo-tagged resources for Web personalization

“…Ricci et al [21] used maps in combination with an interactive critiquing recommender in a mobile environment. Users were able to give qualitative feedback on nearby restaurants and the system iteratively proposed alternatives.…”

InTourMobile: uma Ferramenta de Autoria para o Desenvolvimento de Narrativas para Roteiros Turísticos

“…A literatura é composta por um grande número de estudos que abordam esta problemática, fornecendo uma solução viável. Em sua maioria, as tecnologias ubíquas (e.g., dispositivos móveis e vestíveis) são utilizadas para mitigar estas limitações, fornecendo recomendações de roteiros personalizados [1,15,16,18,21]. A seguir, apresentamos os guias turísticos móveis que apresentam soluções adequadas neste contexto.…”

“…Atualmente, existe um grande número de estudos que conceberam sistemas de recomendação móvel aplicados ao âmbito do turismo [16,17,21]. Yu e Chang [21] conceberam um dos primeiros estudos nesta área, onde seu objetivo é oferecer serviços de recomendações baseados em localização.…”

“…A abordagem apresentada consiste em emitir recomendações a partir da combinação entre as preferências dos usuários e informações de contexto (localização e tempo). Ricce et al [16] concebeu um aplicativo móvel denominado MapMobyRek, que fornece uma interface intuitiva para mostrar as recomendações utilizando listas e mapas para esta tarefa. GeOasis [17] é um guia turístico móvel que integra um serviço de recomendação.…”

A Collaborative Location Based Travel Recommendation System through Enhanced Rating Prediction for the Group of Users

“…MapMobyRek [ 52 ] is another mobile based system that takes advantages of the interface by using maps and lists to provide the recommendations effectively. Comparison of places and items based on their characteristics was facilitated by side-by-side display which helped us to decide among recommendations.…”
