In this paper, we propose a framework named UMT (User-profile Modeling based on Transactional data) for modeling user group profiles based on the transactional data. UMT is a generic framework for a pplication systems that keep the historical transactions of their users. In UMT, user group profiles consist of three types: basic information attribut...

Web 2.0 and its services, such as social networks, have significantly influenced various businesses, including e-commerce. As a result, we face a new generation of e-commerce called Social Commerce. On the other hand, in the tourism industry, a variety of services and products are provided. The dramatic rise in the number of options in travel packages, hotels, tourist attractions, etc. put users in a difficult situation to find what they need. For a reason, tourism recommender systems have been considered by researchers and businesses as a solution. Since tourist attractions are often the reason for travelling, this research proposes a social-hybrid recommender system in the context of social commerce that recommends tourist attractions. The purpose of the research is presenting a personalized list of tourist attractions for each tourist based on the similarity of users' desires and interests, trust, reputation, relationships, and social communities. Compared with the traditional methods, collaborative filtering, content-based, and hybrid, the advantage of the proposed method is the use of various factors and the inclusion of trust factors in recommendation resources, (such as outlier detection in user ratings), and employing social relationships among individuals. The experimental results show the superiority of the proposed method over other common methods. The proposed method can also be used to recommend other products and services in the tourism industry and other social commerce. Read more: https://authors.elsevier.com/c/1abeE3PiGTFIFF

Chapter
Personalized software has been extensively used in museum guides and recommendation systems for tours because it provides added value to the interaction of the user with cultural heritage. However, this added value can only be confirmed through an evaluation experiment. Therefore, this chapter presents the indoor and outdoor personalized tours for exploring cultural heritage. More specifically, the chapter focuses on the methods used for personalization, the technology employed to improve interaction, and the evaluation experiments that have been implemented. The evaluation experiments are further categorized with respect to the method of evaluation and the criteria used. Finally, it provides a discussion on the main conclusions drawn from the researchers conducting evaluation experiments of the system performing indoor and outdoor tours for the exploration of cultural heritage.
... In micro-blog social networks, most recommender systems adopt collaborative filtering or hybrid strategies to provide users with numerous valuable information from similar users [16][17][18].

... As a result, it is time consuming to find interest from all similar followee users. Diverse interest mining from representative users can be used to decision analysis, vote, e-commerce, web search engines, socialized recommender systems and museum visitors' quality of experience and other fields [4,16,[18][19][20][21]. Thus, it is reasonable that the followees could be replaced by a dissimilar and representative group to GUP for recommendation [7,10,19]. ...
... Based on user behavior modeling and user satisfaction capturing, Tsiropoulou et al. [27] adopted optimal and heuristic strategies to design a social recommendation and personalization approach, which can recommend a set of exhibits to the visitors. Considering basic information attributes, synthetic attributes and probability distribution attributes, Yang et al. [16] designed a framework named UMT (User-profile Modeling based on Transactional data) for modeling group profiles, which is suitable for personalization of transaction-based commercial application systems. Using social annotations, Mezghani et al. [28] contributed on characteristics of social user and techniques about modeling tag-based user profile and updating corresponding profiles for recommendation. ...

How to find a user’s interest from similar users a fundamental research problems in socialized recommender systems. Despite significant advances, there exists diversity loss for the majority of recommender systems. With this paper, for expanding the user’s interest, we overcome this challenge by using representative and diverse similar users from followees. First, we model a personal user profile vector via word2vec and term frequency mechanisms. According to user profiles and their follow relationships, we compute content interaction similarity and follow interaction similarity. Second, by combining two kinds of interaction similarity, we calculate the social similarity and discover a diverse group with coverage and dissimilarity. The users in a diverse group can distinguish each other and cover the whole followees, which can model a group user profile (GUP). Then, by tracking the changes of followee set, we heuristically adjust the number of diverse group users and construct an adaptive GUP. Finally, we conduct experiments on Sina Weibo datasets for recommendation, and the experimental results demonstrate that the proposed GUP outperforms conventional approaches for diverse recommendation.
... Furthermore, a user's characteristics may change over time. Some systems that use stereotypical techniques for personalizing the presentation of cultural sights to tourists are AVANTI (Fink et al. 1996, Fink et al. 1998), INTRIGUE (Ardissono et al. 2003) and UMT (Yang and Marques 2005). However, a main problem that such systems encounter is that each user differentiates from all the others in many ways. ...

Internet has significantly influenced the tourism sector providing a great variety of services and products online. However, the number of choices has increased so dramatically that is very difficult for the consumers to find what they are looking for. For this purpose, recommendation systems for tourism have attracted a lot of research energy and interest. The main characteristic of these systems is that they can personalize their recommendations to each user interacting with the system. Personalization is even more essential for tourism recommendation systems used in handheld devices where the screen is even smaller and the presentation capabilities are limited. This paper addresses these problems and provides some development steps for a tourism recommendation system by making a state of the art in personalized e-tourism services both in computers and handheld devices as well as a review of the user modeling and personalization techniques used in these systems. Furthermore, the theories used for the improvement of the personalization procedure in tourism recommendation systems; their applications and evaluation are discussed.
... ity between user and tag. K. R. Bayyapu and P. Dolog in [2] tries to solve the problems of sparse data and low quality of tags from related domains. They suggest using tag neighbors for tag expression expansion. However the tag neighbors are based on the content of documents. We propose another approach to extend the tag set by the group profiling. [19] uses a framework of User-Profile Modeling based on Transactional data for modeling user group profiles based on the transactional data which can incorporate external information, either by means of an internal knowledge base or on dynamic data supplied by a specific information extraction system. Such user group profiles consist of thre ...

In this paper, we propose a spectral cluster-ing approach for users and documents group modeling in order to capture the common preference and relatedness of users and doc-uments, and to reduce the time complexity of similarity calculations. In experiments, we investigate the selection of the optimal amount of clusters. We also show a reduc-tion of the time consuming in calculating the similarity for the recommender systems by se-lecting a centroid first, and then compare the inside item on behalf of each group.

Currently, tourism providers build tourist models by collecting some specific pieces of information and then combining the knowledge they have about the groups to which current tourists belong. This paper presents the BaliaTour user modelling and Recommender System, which combines several techniques and methodologies in order to enhance the modelling process when scarce of data about an individual tourist is available. The core of the model is based on the predictions made over stereotypes as a initial characterization of the user profile. The modelling is further refined and enhanced by the combination of explicit preferences and ratings provided by the user. As a result, the proposed approach takes advantage of every information piece known about tourists in tourism ecosystems. The main advantage of BaliaTour is to minimize the main drawbacks of each of the existing user modelling techniques to obtain a user model.

Personalization has an important role in information systems. It is an effective solution for reducing complexity when searching information. In this way, the user feels like the system was developed for him/her. In this context, personalization can be seen as an optimization problem. To this end, we propose a multi-criteria decision making approach to personalize system. The proposed approach has been validated by applying it to personalize a system in intelligent transport field.
