Taking Ziyin Oilfield in Baise area of Guangxi Province as an example, the seismic attribute analysis technology and its application to prediction of reservoirs in the oilfield were introduced. The seismic attribute analysis technology consists of three aspects. The first one is to pick all kinds of seismic attributes kept in the seismic data and associated with lithology and the physical characters of reservoir by various mathematics analysis methods. The second one is to optimize the seismic attributes on the basis of rough set (RS) theory. And the third one is to transform the reservoir parameters by combining interpretation results of the logging data in the project and to accomplish integration estimation for the reservoir by using multi attribute and predicted reservoir parameters. The application of real seismic data indicated that the seismic attribute analysis technology is efficient for the exploration and exploitation recycle period of an oilfield. The application results of this technology in Ziyin Oilfield may provide a reliable basis for oilfield production.

Conformity Influence Meeting Evolving Consumer Experience in Recommender Systems

Yong Wang Li Li

Nowadays, recommender systems have become a hot research area. It plays an important role in providing personalized information. Recent research has considered the evolution of consumer tastes over time. But these studies are all from the perspective of the community to study the evolution of the overall taste. As a matter of fact, because of the different personal experiences, each person's tastes will evolve in different ways. In this paper, we consider the evolution of tastes on a personal level. At the same time, we model the influence of conformity psychology. That is, to consider the impact of public ratings on consumers at different levels of experience. Finally, we proposed the Experience and Conformity Probability Decomposition (ec-MF) model and apply the model to three real data sets. Experiments show that our model achieves better results. Besides, We find that there is a close connection between the level of personal experience and the conformity mentality. There are also significant differences in rating behaviors among consumers at different experience levels.

Usability Measurement Using a Fuzzy Simulation Approach

International Conference on Computer Modeling and Simulation (2009)

Liang Lu Xiaoling Deng Yong Wang

Usability is a three-dimensional quality of software product, encompassing efficiency, effectiveness and satisfaction. Satisfaction always relies on subjective judgment, but on some degree, the measurement of efficiency and effectiveness is able to be objectively calculated by some approaches, which can help designers to compare different prototype design candidates in the early stage of product development. To address the limitation of state-redundancy and inter-uncertainty of FSM, this paper introduces an existing approach to simplify a general FSM by reducing the redundant states, and proposes a fuzzy mathematical formula for calculating the probability of state-transition. Then, an algorithm for measuring efficiency and effectiveness data on simulated FSM is designed based on the fuzzy function. This measurement approach is very appropriate to be applied on the small-medium types of embedded software in practice.
