The rapid urban expansion has greatly extended the physical boundary of users’ living area and developed a large number of POIs (points of interest). POI recommendation is a task that facilitates users’ urban exploration and helps them filter uninteresting POIs for decision making. While existing work of POI recommendation on location-based social networks (LBSNs) discovers the spatial, tempora...

Nowadays, many configurable products and services are sold via web. For supporting a customer in configuring the desired product, the interaction with the configurator has to be personalised according to the user's interests. In this paper, we show how these interests can be estimated. In an idealisation, we ascribe the Multi-Attribute Utility Theory as evaluation process to the user. Based on ...

This paper presents an image retrieval method based on keyblocks combing with interest points, furthermore the generation of codebook is also utilized to enhance the retrieval performance, where the balance between the retrieved precision and time cost can decide the codebook size of this CBIR system. Finally, the proposed method is compared with the method that only depends on interest points ...

In content-based image retrieval (CBIR), the user usually poses several labelled images and then the system attempts to retrieve all the images relevant to the target concept defined by these labelled images. It may be helpful if the system can return relevant images where the regions of interest (ROI) are explicitly located. In this paper, this task is accomplished with the help of multi-insta...

If our moral beliefs rest on a mistake, as error theorists claim, what should we do with them? According to Richard Joyce’s revolutionary fictionalism, pretend believe propositions in order keep the benefits thinking has for their preference satisfaction. This, he claims, frees theory from radical practical implications. In response, I argue that implementing fictionalism would not preserve pra...

Location-based games entertain players usually by interactions at points of interest (POIs). Navigation between POIs often involve the use of either a physical or digital map, not taking advantage of the opportunity available to engage users in activities between POIs. The paper presents riddle solving as a navigational method for a location-based game. 10 families with 2-6 persons and at least...

With the gradual maturating of ubiquitous computing and the rapid advances in mobile devices and wireless communication, indoor Location Based Services have gained increasing interests as an important application of indoor ubiquitous computing. In this paper, we propose an evaluation framework which combines the key aspects of indoor navigation for investigating mobile indoor navigation systems...

Point-of-interest (POI) recommendation is an important service to Location-Based Social Networks (LBSNs) that can benefit both users and businesses. In recent years, a number of POI recommender systems have been proposed, but there is still a lack of systematical comparison thereof. In this paper, we provide an allaround evaluation of 12 state-of-the-art POI recommendation models. From the eval...

Agent-based simulations are expected to enable analysis of complex social phenomena. In such simulations, one of the important behaviors of the agents is negotiation. Throughout the negotiations, the agents can make complex interactions with each other. Therefore, the ability of agents to perform negotiation is important in simulations of artificial societies. In this paper, we focus on price n...
