Collaborating Filtering Community Image Recommendation System Based on Scene

Abstract

Abstract-With the advancement of smart city, the development of intelligent mobile terminal and wireless network, the traditional text information service no longer meet the needs of the community residents, community image service appeared as a new media service. "There are pictures of the truth" has become a community residents to understand and master the new dynamic community, image information service has become a new information service. However, there are two major problems in image information service. Firstly, the underlying eigenvalues extracted by current image feature extraction techniques are difficult for users to understand, and there is a semantic gap between the image content itself and the user's understanding; secondly, in community life of the image data increasing quickly, it is difficult to find their own interested image data. Aiming at the two problems, this paper proposes a unified image semantic scene model to express the image content. On this basis, a collaborative filtering recommendation model of fusion scene semantics is proposed. In the recommendation model, a comprehensiveness and accuracy user interest model is proposed to improve the recommendation quality. The results of the present study have achieved good results in the pilot cities of Wenzhou and Yan'an, and it is applied normally.

Emerging Perspectives on the Application of Recommender Systems in Smart Cities

“…The second cluster has the collaborative filtering technique based on user behaviour as its core. In addition to data, this technique needs elements such as algorithms, crowdsourcing, matrix factorization, and optimisation to operate [19,[49][50][51][52]. The third cluster gives evidence of the direct relationship between recommender systems, big data, and data mining [53][54][55][56] These systems use algorithms and artificial intelligence techniques to analyse past and present user behaviour in order to provide personalised recommendations.…”

Recommender systems for smart cities

“…Supporting community building and urban life management. With the goal of enabling urban residents to better enjoy community life, He et al (2017) developed a participatory sensing application, whereas Kinawy et al (2018) proposed a system to share community project information with citizens.…”
