The paper studies a practical problem of resource assignment and optimal human resource allocation scheduling with the objective of minimizing employees' useless working time and retire some workers. We analyze simultaneous employment staff with different competencies (skills) that needed to complete jobs. Each job and worker have a set of individual parameters. The mathematical model of assignment...
Crowdsourcing coordinates a large group of workers online to do self-contained small tasks that are published by job requesters on a crowdsourcing platform. Many papers propose incentive strategies to motivate workers to participate in crowdsourcing. In this paper, we shift the focus from the workers to the job requesters by addressing two of their issues: how to design a good payment scheme to maximize...
Privacy preserving of multi-sensitive attributes datasets (MSA-Datasets) has received increasing attention because of its huge social and economic benefits. In this paper, we introduce a novel and general privacy framework called Transparent Link. The Transparent Link framework can be used to anonymize MSA-Datasets by designing an algorithm based on probabilistic graphical model, which is referred...
The traditional relational database model may be extended into a fuzzy database model based on the mathematical framework of fuzzy set theory to process imprecise or uncertain information. While designing such a fuzzy relational database model that does not suffer from data redundancy and anomalies, the present authors have defined several fuzzy normal forms in ref [1]. However, as one decomposes...
With the popularity of social networks, data privacy preserving in social networks has become a hot issue among scholars. An attacker can use a variety of background knowledge to attack against privacy. Most of the present technology on anonymity weighted social network graphs can only deal with edge weight, but cannot be applied to sensitive labels. We consider a new generalization approach for sensitive...
In this paper, we propose a checking algorithm for dynamic constraint validation during XML updates. Our algorithm is targeted at single transition constraint, which is affected by single node updating. To the best of our knowledge, almost all constraints that have been preserved in the previous XML updates works are for static constraints. On the other hand, dynamic constraints restrict the transition...
In recent years, anonymization methods have emerged as an important tool to preserver individual privacy when relasing privacy sensitive data. All of these methods are under different privacy and utility assumption. But there has been little research addressing how to effectively use the anonymized data for data mining. Data mining is one of problems for the utility of anonymized data under the k-anonymity...
To meet the needs of desire of using natural language to describe data analysis, this paper combines ideas of both fuzzy query language and linguistic summaries, introduces fuzzy set theory and presents a more powerful algorithm based on relational database, which can find fuzzy rules among crisp data. As a result, an automatic fuzzy rule extraction system is developed, which can support users extract...
