Different from current researches on Flickr group recommendation approaches that recommend groups to either users or images, this work proposes a unified framework that recommends groups to both users and images. Four types of entities in the Flickr system (users, tags, images, and groups) are integrated into a tetradic model, and then we uses tetradic decomposition to discover the latent semantic...
We report on the second design cycle of Acropolis, a social computing platform that allows citizens to build and share their own narratives about long-running news stories. A key goal of this research project is to explore the following design opportunity: how can we re-design news stories in order to engage citizens in their reading and curation? In this paper, we describe an asymmetric collaboration...
Collaborative filtering methods suffer from a data sparsity problem, which indicates that the accuracy of recommendation decreases when the user-item matrix used in recommendation is sparse. To alleviate the data sparsity problem, researches on data imputation have been done. In particular, the zero-injection method, which finds uninteresting items and imputes zero values to those items for collaborative...
Researchers create larger networks of contacts through research collaboration, known as collaboration networks of researchers. In order to promote and to have effective collaboration among researchers, the collaboration patterns need to be accessed and analysed to elevate research and publication (R&P) performance. However, the collaboration patterns have not been accessed in the context of Universiti...
In software development application lifecycle management (ALM) systems are used to support the development process. As these products are tailored for best fitting the applied programs and their actual usage is diverse. Often, this means that products of different vendors are applied, which reduce the reachability between different artefacts and the overall consistency of the system. In this paper...
Adaptive Collaboration (AC) has been proven and verified to be a promising methodology to conduct collaboration. AC follows an iterative and dynamic process that includes phases of role negotiation, agent evaluation, role assignment, role playing, and role transfer. However, AC is complex, and the benefits of AC are not easily observed. In particular, the benefits must be obtained through complicated...
DBpia is the largest digital-bibliography service provider in Korea. It provides several convenience functions for researchers. DBpia users (i.e., researchers) can search for papers via several search routes such as publications, publishers, authors, and keywords. Although the researchers can exploit the search functions, they may still have a number of search results as candidate papers to read....
In this study, a new academic event recommendation method is proposed. This method analyzes author interactions, academic event attendance records, research related, and textual descriptions from attended academic events to measure interaction strength between authors. Experiments on the DBLP dataset and Wiki Calls for Papers (WikiCFP) showed that the proposed method is helpful in improving the accuracy...
In the real-world, there are many criteria to evaluate agents on roles, which are an important factor affecting the result of the group role assignment (GRA). To obtain a satisfied assignment, we need to select an appropriate evaluation method. This paper points out the key issues of the related concepts, formalizes the problem of GRA based on multiple criteria (GRA-MC), investigates three algorithms...
A comprehensive evaluation model of enterprise's partner selection on UIC is established by use of Analytical hierarchical process (AHP) and Grey Fuzzy Evaluation Method. The evaluation index system is built through literature review and expert interview, and then the weight of each index is determined by AHP and the reasonable conversion from qualitative to quantitative is acquired through the application...
To maintain the performance of a group is one objective in collaboration. Adaptive Collaboration (AC) is targeting this aim by conducting multiple role re-assignments during the collaboration process. This paper begins by clarifying AC. Then, the AC problem is formalized based on the Environment-Class, Agent, Role, Group, and Object (E-CARGO) model. Based on the general AC model, we consider a typical...
