The thousands of streaming data overwhelmingly provide for Internet users on Twitter every day, especially for those Twitter users with many friends. However, the useful tweets that users are really interested in personally could be covered by massive other uninformative and uninteresting information. Therefore, how to bring immediately the interesting tweets for users is always a challenging issue...
The proliferation of computers as handheld devices with Internet connectivity along with ecommerce and social networking sites allow the generation of huge amount of data. This data empowers the corporations and other organizations to produce meaningful business patterns from consumers' behavior. Also, they can build recommender systems to predict future social trends which can enhance their services...
Technology is a catalyst for communication and collaboration, and the use of information systems for these applications is prevalent. While there are countless benefits associated with communication and collaboration tools, detriments do exist. One pitfall is the prevalence of deviant behaviors online which can jeopardize the effectiveness of these tools. This paper presents the results of a study...
The paper summarizes the developing trend of Wikipedia which is one of important Internet application using current revision data set. It models the process of mass collaboration in Wikipedia using power distribution, namely Pareto distribution. This model suggests that the majority of edits in Wikipedia is contributed by a small group of people, while most participants in Wikipedia only give minor...
As the competition between firms increases rapidly, it is critical to innovate continuously. Accessing external knowledge is essential to have continuous innovative products. This paper focuses on the virtual community of practice (VCoP), is a type of community of practice but exists virtually for acquiring and sharing external knowledge. To find out users'' intentions of using VCoP, this papr adopts...
Interoperability is a key aspect of collaborative systems especially in massive and highly distributed environments such as the Internet of Things. Know how systems can communicate among themselves in order to lose as little information as possible is a key challenge. To meet this challenge one needs to set methods to measure the Interoperability Capacity in the communication between two systems....
As we all know, the World Wide Web is becoming a large source of images. Thus, it is manifest that the demand for image recommendation systems is increasing rapidly. There are several image recommendation systems for both commercial and academic areas, which deals with the user preference being fixed. However, since the Images preferred by a user may change depending on the contexts, the conventional...
Collaborative Recommender system helps the online users to identify the right product during electronic purchasing. The collaborative recommender system identifies the similar users based on the purchasing or rating behavior to the active user and then recommends the product based on the similar users. Collaborative recommender system is widely used in majority of the existing online recommender system...
In Web 2.0, there is no clear distinction between users and webmasters. Many internet users are not only information consumers but also information providers. There are lots of information in the Web and most people can find what they want by searching the Web. One problem of the large number of data in the Web is that we often spend most of our time to find a correct result from search results. Thus,...
The World Wide Web has created a new media for mass marketing that can also be highly customized to online customers' needs and expectations. Recommender Systems (RS) play an important role in this area. Here, we aim to establish a genre-based collaborative RS to automatically suggest and rank a list of appropriate items (movies) to a user based on the user profile and the past voting patterns of...
CDIO is a new education model, which cultures students' specialized technical knowledge, individual ability, professional ability and ability of working and communicating in team towards systemic product design. We obtain practical experience using organic combination between document retrieval and analog electronic technology, and try out a teaching model of document retrieval combined with specialized...
Complex networks consisting of humans and software services, such as Web-based social and collaborative environments, typically require flexible and context-based interaction models. Due to the dynamics in such systems, networks are in a state of constant flux and change. Several fundamental concepts, including discovery, interactions, task delegations and executions are no longer based on static...
Collaborative tagging is a popular method in social resource sharing system. The reason why collaborative tagging system becomes popular is users can freely tags on the resources, like Flickr1 and Delicious2. Any relationship between tags and resources are not made explicitly when tagging in folksonomy. Due to lack of semantic meaning, it is difficult for users to find related resources. Also, short...
The blogosphere is a part of the Web, enhanced with several characteristics that differentiate blogs from traditional websites. The number of different authors, the multitude of user-provided tags, the inherent connectivity between blogs and bloggers, the high update rate, and the time information attached to each post are some of the features that can be exploited in various information retrieval...
Point out the fuzziness and uncertainty of user preferences. Put forward the advantage of using cloud model to calculate the user preferences. Introduce the cloud model and construct the model of user preferences based on cloud model. Design one new algorithm for calculating the user preferences with time weight. The experiments show the personalized recommend based on the new user preferences has...
Design thinking, as a complex system, can be described as complex network. We constructed design thinking networks from analysing verbal protocols acquired form a design experiment conducted with think-aloud method. The characteristic path length and the clustering coefficient of the design thinking networks were calculated and compared with that of the equivalent random graphs. Result indicates that...
The stigmergy collaboration approach provides a hypothesized explanation about how online groups work together. In this research, we presented a stigmergy approach for building an agent based open source software (OSS) developer community collaboration simulation. We used group of actors who collaborate on OSS projects as our frame of reference and investigated how the choices actors make in contribution...
Recently researchers have argued that the prevailing view of Web search, as a solitary activity, is flawed: that, in reality, Web search can be an inherently collaborative task. In this paper we describe and evaluate an approach to collaborative Web search that seeks to enhance mainstream search engines by harnessing the past search experiences of communities of like-minded searchers in order to adapt...
Human computation is a technique that makes use of human abilities for computation to solve problems. Social games use the power of the Internet game players to solve human computation problems. In previous works, many social games were proposed and were quite successful, but no formal framework exists for designing social games in general. A formal framework is important because it lists out the...
In order to users be able to find their own favorite resources quickly and accurately, this paper presents a personalized service which recommends resources for users at massive education resources net. On the basis of analyzing the characteristics of users and resources, this paper discusses the model of resourcepsilas description and userpsilas interest, and the treatment of userpsilas interest...
