With the increasing tendency of information technology (IT) applications, knowledge integration in organization has emerged as an important research topic for both practitioners and researchers, reflecting the magnitude and impact of knowledge resource in distributed environments. Practically, data, information, and knowledge are transmitted via various media, and integration capability is the antecedent of knowledge integration in organizations. However, few literatures research knowledge integration from the comprehensive perspective of transmission media and integration capability. As a complement to previous research, this study proposes a comprehensive theoretical model of knowledge integration (KIM) by incorporating valuable perspectives of media characteristics and organizational capability. This research model provides a new lens for knowledge integration based on transmission media in organizations by integrating relevant research streams. Furthermore, this robust and new model, which has been applied to a knowledge integration practice of e-commerce platform, can be used to explain the most knowledge integration phenomenon in contemporary society.

Spatial-keyword queries on road networks are receiving increasing attention with the prominence of location-based services. There is a growing need to handle queries on road networks in distributed environments because a large network is typically distributed over multiple machines and it will improve query throughput. However, all the existing work on spatial keyword queries is based on a centralized setting. In this paper, we develop a distributed solution to answering spatial keyword queries on road networks. Example queries include "find locations near a supermarket and a hospital," and "find Chinese restaurants within 500 meters from my current location." We define an operation for answering such queries and reduce the problem of answering a query into computing a function of such operations. We propose a new distributed index that enables each machine to independently evaluate the operation on its network fragment in a distributed setting. We theoretically prove the space optimality of the proposed index technique. We conduct experiments with a distributed setting. Experimental results demonstrate the promising performance of our method.

Full eigenvalues of the Markov matrix for scale-free polymer networks

Physical Review E 2014年第2期90卷 022816-022816页

Much important information about the structural and dynamical properties of complex systems can be extracted from the eigenvalues and eigenvectors of a Markov matrix associated with random walks performed on these systems, and spectral methods have become an indispensable tool in the complex system analysis. In this paper, we study the Markov matrix of a class of scale-free polymer networks. We present an exact analytical expression for all the eigenvalues and determine explicitly their multiplicities. We then use the obtained eigenvalues to derive an explicit formula for the random target access time for random walks on the studied networks. Furthermore, based on the link between the eigenvalues of the Markov matrix and the number of spanning trees, we confirm the validity of the obtained eigenvalues and their corresponding degeneracies.

This paper describes the Antinomyra System that participated in the BioASQ Task 2a Challenge for the large-scale biomedical semantic indexing. The system can automatically annotate MeSH terms for MEDLINE citations using only title and abstract information. With respect to the official test set (batch 3, week 5), based on 1867 annotated citations out of all 4533 citations (June 6, 2014), our best submission achieved 0.6199 in flat Micro F-measure. This is 9.8% higher than the performance of official NLM solution Medical Text Indexer (MTI), which achieved 0.5647 in flat F-measure.

Geometric correction is an essential processing procedure in remote sensing image processing. The algorithms used in geometric correction are time intensive and the size of remote sensing images is very large. Meanwhile, the data to be calculated is in huge size and is accumulating rapidly every day. Hence, the fast processing of geometric correction of remote sensing image becomes an urgent research problem. Through the rapid development of GPU, the current GPU has a great advantage in processing speed and memory bandwidth over CPU. It provides a new way for high performance computing. In this paper, we present three optimization solutions based on CPU-GPU hybrid architecture and the analysis of their performances. Experiments are also given and the results are consistent with the analysis. © (2014) Trans Tech Publications, Switzerland.

Protein-protein interaction (PPI) networks are crucial for organisms. Many research efforts have thus been devoted to the study on the topological properties PPI networks. However, existing studies did not always report consistent results on the topological properties of PPI networks. This situation is primarily caused by the incompleteness of current PPI datasets. To solve this problem, in this paper we revisited the topological properties of PPI networks from the perspective of PPI dataset evolution. Concretely, we used twelve PPI datasets of Arabidopsis thaliana from different BioGRID database versions, and compared the topological properties of PPI networks built from the twelve datasets. Our results show that as the dataset evolves, the PPI network becomes more and more complete, all considered topological properties seemingly converge to stable values, which possibly indicate the topological nature of the complete Arabidopsis thaliana PPI network. Such findings can not be obtained from a few datasets as used in the existing works.

Generalized Unsupervised Manifold Alignment 14

Generalized Unsupervised Manifold Alignment

Proceedings of the 28th International Conference on Neural information processing Systems - Volume 2

作者： Zhen Cui Hong Chang Shiguang Shan Xilin Chen Key Lab of Intelligent Information Processing of Chinese Academy of Sciences (CAS) Institute of Computing Technology CAS Beijing China and School of Computer Science and Technology Huaqiao University Xiamen China Key Lab of Intelligent Information Processing of Chinese Academy of Sciences (CAS) Institute of Computing Technology CAS Beijing China

In this paper, we propose a Generalized Unsupervised Manifold Alignment (GU-MA) method to build the connections between different but correlated datasets without any known correspondences. Based on the assumption that datasets of the same theme usually have similar manifold structures, GUMA is formulated into an explicit integer optimization problem considering the structure matching and preserving criteria, as well as the feature comparability of the corresponding points in the mutual embedding space. The main benefits of this model include: (1) simultaneous discovery and alignment of manifold structures; (2) fully unsuper-vised matching without any pre-specified correspondences; (3) efficient iterative alignment without computations in all permutation cases. Experimental results on dataset matching and real-world applications demonstrate the effectiveness and the practicability of our manifold alignment method.
