Collaborative tensor–topic factorization model for personalized activity recommendation

Tongcun Liu, Jianxin Liao, Yulong Wang, Jingyu Wang, more

Multimedia Tools and Applications > 2019 > 78 > 12 > 16923- 16943

Activity recommendation is a new aspect of location-based social networks (LBSNs) that is being increasingly researched in academia and industry. Previous studies focus mainly on the identification of behavioral regularity by users and use sporadic check-in data, so they suffer severely from data sparsity problems and provide inaccurate recommendations. Furthermore, tips that imply a user’s interests...

Incentive Mechanisms for Resource Scaling-out Game of Stream Big Data Analytics

Xiaoyuan Fu, Jingyu Wang, Qi Qi, Jianxin Liao, more

Journal of Grid Computing > 2018 > 16 > 4 > 569-585

For stream big data analytics, a participated task always needs to scale out resources when its input data increases steeply. Typically, the resource scaling-out can be achieved by increasing the parallelism degree of the platform based on the experience. However, the resource scaling-out of each task produces additional cost not only from itself but also from other competitive tasks, which brings...

Neurocomputing > 2018 > 278 > C > 119-125

Vectorized representations as an important data representation way play an essential role in many data mining applications. Now, more and more applications are based on multi-typed information network, such as social networks, which is called heterogeneous networks. However, most data in heterogeneous networks are far from Gaussian distribution. Gaussian models are inappropriate choices to model such...

Computer Networks > 2017 > 112 > C > 24-35

Software Defined Networking (SDN) decouples control and data planes. The separation arises a problem known as the controller placement, i.e., how many and where controllers should be deployed. Currently, most works defined this problem as the multi-objective combinatorial optimization problem and used heuristic algorithms to search the optimal solution. However, these heuristic algorithms have the...

2016 IEEE 41st Conference on Local Computer Networks (LCN) > 236 - 239

2016 IEEE 41st Conference on Local Computer Networks (LCN)

The overlay network has been widely developed in recent years. There may be various overlays that co-exist with each other upon the same underlying network. These overlays have heterogeneous performance goals, and they will compete for the physical resources, so that a sub-optimal performance of the overlays may be achieved. Moreover, the heterogeneity of the overlays makes them difficult to coordinate...

Lightweight approach for multi-objective web service composition

Jianxin Liao, Yang Liu, Jing Wang, Jingyu Wang, more

IET Software > 2016 > 10 > 4 > 116 - 124

Service composition is an efficient way to implement a service of complex business process in heterogeneous environment. Existing service selection methods mainly utilise fitness function or constraint technique to convert multiple objectives service composition problems to single objective ones. These methods need to take effect with priori knowledge of problem's solution space. Besides, in each...

Jianxin Liao, Lei Zhang, Tonghong Li, Jingyu Wang, more

IET Software > 2016 > 10 > 6 > 182 - 188

Scheduling tasks close to their data and optimising resources utilisation are both crucial for the efficiency of MapReduce system. On the other hand, there is a conflict between fairness and efficiency. In this study, an efficient and dominant resource held time fairness (EHTF) scheduler is presented, in which the efficient utilisation of resources, data locality and fairness are addressed simultaneously...

IEEE Transactions on Services Computing > 2016 > 9 > 4 > 580 - 593

This paper focuses on matching ontologies created for similar domains through different sources. Different solutions use lexical, structural or logical processing and analysis to match ontologies. However, an important aspect is also interpreting concepts that entities are presented with and using them in relation to semantics in an ontology. The paper demonstrates analyzing and extending the concepts...

IET Communications > 2016 > 10 > 9 > 1053 - 1062

Existing rateless codes have a very low intermediate symbol recovery rate. Therefore, a new analysis method named iterative and small degree first (I-SDF) is presented for the design of optimised partial recovery Luby transform codes (PR-LTC) in this study. On the basis of I-SDF, the required number of encoded symbols with degree d in each decoding step is calculated by an iterative optimisation algorithm...
