Accessible POI Recommendation Using Adaptive Aggregation of Binary Ratings

Everyone needs one or more forms of accessibility at some point in life due to age, medical conditions, accidents, etc. People with accessibility needs have the right to accessible services, as well as the right to information about accessibility at various places or Points of Interest (POI). While most popular POI recommendation services do not take accessibility into account, some of them only consider a few specific needs, such as ramp for wheelchair users. However, different users have different accessibility needs regarding the structure of the building, special aid devices, and facilities to be able to independently visit a place. The proposed system focuses on finding the personalized accessibility score for a (user, POI) pair. It can be used with other factors such as historical behavior, social influence, geographical conditions, etc. to recommend accessible places. It uses time decaying aggregate on the crowd-sourced binary rating data to find accurate approximation of current accessibility status for each accessibility criteria. Also, we propose a tunnel-based algorithm to detect the trend of binary stream data to update the rate of decay. This ensures that the calculated aggregate adapts to change in the accessibility status of the place

Service Recommendation System for a Smart City

Smart Cities are complex spaces with a variety of information and points of interest, in which citizens can have access, whether visitors or residents. This paper presents a system of recommendation of points of interest in smart cities, aiming to improve the result of the search performed by the user. For this, an ontological model was used, through a case study, adding data from a city. Through this study, it is possible to demonstrate the potential of an ontological modeling to provide recommendations. These improve semantics and create standardization to facilitate knowledge sharing. The approach developed aims to recommend information from sights and health services. To test the system, SWRL rules were developed and, from them, inferences are made by a reasoner

Context-Driven Tour Planning Service: An Approach Based on Synthetic Coordinates Recommendation

The paper presents a hybrid context/model-based tour planning service aimed at recommendation generation by providing the tourists the sequence of attractions that are more interesting for him/her based on previous activity with the service. The service is developed based on SCoR recommender system that is aimed at recommendation generation based on calculating the synthetic coordinate between tourists of the service in according with their ratings. SCoR is a model-based collaborative filtering algorithm, constructing a model based on the user's personal ratings as well as exploiting collaborative information from the ratings of the rest of the users. One of the main advantages of SCoR's model is its ability to incorporate additional training information (new ratings) without having to perform the training process from the beginning. The prototype has been implemented for Android-based smartphone and has been evaluated for St. Petersburg city. For the evaluation the attraction database has been formed that includes attraction location information from OpenStreeMaps platform, location description and media from Wikipedia, and ratings from Google Place

Accessibility of mobile applications for tourism - is equal access a reality?

With the increasing use of smartphones in people’s daily lives, mobile accessibility has become a key factor for them. Tourism is one of the sectors that has benefited the most from this growth but has not yet reached its full potential as accessibility has not yet been fully exploited. The main goal of this study is to assess accessibility in mobile applications for the tourism sector. Thus, 14 mobile applications were analyzed, using a manual and automatic methodology through the proposal of an evaluation model divided by quantitative and qualitative requirements, as well as the use of features such as VoiceOver and TalkBack. The results show a high overall number of errors in most quantitative requirements as well as non-compliance with most qualitative requirements. On iPhone 4, “Viseu – Guia da Cidade” was the application with the highest rating, while on Wiko GOA, it was the “JiTT.Travel Funchal” application. In turn, on iPhone 6 Plus, iPhone XR, Nokia 5.1 and OnePlus 6 devices, the best results were achieved by the “Viseu – Guia da Cidade,” “JiTT.Travel Funchal” and “TUR4all” applications. Regarding the accessibility of mobile applications on different versions of the same mobile operating system, it was concluded that there are no differences in their accessibility on both operating systems (iOS and Android). Finally, regarding the accessibility of applications on smartphones with different screen sizes, there are also no differences in their accessibility.This work is financed by the ERDF—European Regional Development Fund through the Operational Programme for Competitiveness and Internationalisation—COMPETE 2020 Programme, and by National Funds through the Portuguese funding agency, FCT-Fundação para a Ciência e a Tecnologia within project POCI-01-0145-FEDER-031309 entitled “PromoTourVR-Promoting Tourism Destinations with Multisensory Immersive Media.”info:eu-repo/semantics/publishedVersio

Conflating point of interest (POI) data: A systematic review of matching methods

Point of interest (POI) data provide digital representations of places in the real world, and have been increasingly used to understand human-place interactions, support urban management, and build smart cities. Many POI datasets have been developed, which often have different geographic coverages, attribute focuses, and data quality. From time to time, researchers may need to conflate two or more POI datasets in order to build a better representation of the places in the study areas. While various POI conflation methods have been developed, there lacks a systematic review, and consequently, it is difficult for researchers new to POI conflation to quickly grasp and use these existing methods. This paper fills such a gap. Following the protocol of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), we conduct a systematic review by searching through three bibliographic databases using reproducible syntax to identify related studies. We then focus on a main step of POI conflation, i.e., POI matching, and systematically summarize and categorize the identified methods. Current limitations and future opportunities are discussed afterwards. We hope that this review can provide some guidance for researchers interested in conflating POI datasets for their research

Access to urban parks: Comparing spatial accessibility measures using three GIS-based approaches

Urban parks are essential components of urban ecosystems, providing recreation and relaxation places to residents. Measuring the spatial accessibility to urban parks serves as an initial step in urban planning and developing urban development strategies to improve social and environmental justice. This study aims to evaluate measures of spatial accessibility to urban parks by comparing three geographic information systems (GIS)-based approaches, accounting for network complexity, transport modes, distance thresholds, and destination choices. Taking Ipswich City (Australia) and Enschede (the Netherlands) as two testbeds, we examine the spatial patterns of a total of 21 accessibility measures in the two cities and conduct a correlation and principal component analysis to unravel the interrelationship between these measures. The results suggest that among all measures under the three approaches, the selection of distance thresholds and transport modes matter more to accessibility measures than the destination choices. Furthermore, when distance threshold and transport mode are held constant, the network-based and entrance-based methods provide more realistic accessibility measures than other methods. We also discuss the generality of the entrance-based method we propose and suggest ways to choose the most appropriate accessibility measure for use in different contexts

Sistema de recomendação de serviços para uma cidade inteligente

Cidades Inteligentes são espaços complexos com variedade de informações, no qual os cidadãos podem ter acesso, sejam eles visitantes ou residentes. Denominado de pontos de interesse (POIs) as informações relacionadas a uma cidade, estando estes POIs espalhados ou concentrados no mesmo local. Ao buscar interesses, o usuário utiliza meios tradicionais de pesquisa, que por vezes não retornam exatamente o local ou serviço desejado. Visando melhorar o resultado da busca, foi utilizado um modelo ontológico, através de um estudo de caso, adicionando dados da cidade de Cotiporã/RS. Através deste estudo é possível mostrar que uma das formas de se modelar um sistema de recomendação é com base nas ontologias. Essas melhoram a semântica e criam uma padronização na web para facilitar o compartilhamento do conhecimento. A abordagem desenvolvida tem por objetivo recomendar POIs turísticos e serviços da área da saúde. Para avaliar o protótipo, foram desenvolvidas regras SWRL inferidas utilizando o motor de inferências Pellet, onde, baseado nas preferências do usuário, o protótipo retorna o resultado da busca efetuada através da localização do usuário, apresentando na interface. Com esta proposta é possível continuar o projeto ampliando os filtros de recomendação para outros setores e ampliar o projeto para outras cidades.Smart Cities are complex spaces with a variety of information, which citizens can access, whether they are visitors or residents.
