Microblog has become a daily communication tool in recent years. Researches on microblog have drawn more and more attention. Microblogging emotional classification is a major research of user intent analysis based on User-Generated Content (UGC). This paper focuses on the discrimination on two emotional tendencies: positive and negative. Firstly, the system cleared the noisy elements in the microblog,...
The spatial pattern of prehistoric settlement sites in Henan Province is researched. By analyzing the relationship between prehistoric settlement sites location and regional altitude, terrain slope, rivers and other geographical environment factors, the laws of the distribution of prehistoric settlement sites are found: more than 70% of settlement sites are located at the altitude of from 50 to 400...
Cultivating customer loyalty is the objective of enterprise management, have an enormous impact to the enterprise efficiency. In this pape, we apply decision tree algorithm to classify the customer resource, and having mined the ideal customer. Basing on the analysis of customer behavior, to comparative analysis and evaluation of customer loyalty. Finally we achieve customer loyalty assessment and...
There are many uncertainties and knowledge redundancy in fault diagnosis while the rough set theory is a new the mathematical tools to deal with the uncertainty of information. The rough set theory provides a a new effective way of dealing with the mechanical fault diagnosis . This paper presents a method of discretization which can be used in incomplete continuous information processing, and uses...
In this paper, we show that the images of the circular points can be identified by solving the intersection of two imaged coplanar circles under projective transformation and thus metric planar rectification can be achieved. The advantage of this approach is that it eliminates the troublesome camera calibration or vanishing line identification step that underlies many previous approaches and makes...
In this letter, we present the exact sum-rate analysis of the multiuser multiple-input multiple-output (MIMO) systems with zero-forcing transmit beamforming (ZFBF). We develop the analytical expressions of the ergodic sum-rate for two low-complexity user selection strategies for the dual-transmit-antenna scenario. Based on the analytical results, we examine the parameter optimization problem to properly...
