precision attribute

Product attribute extraction is a very valuable task for sentiment analysis. In order to improve the precision of product attributes extraction, we apply Conditional Random Field ( CRF) model and Maximum Entropy ( ME) model with the combination of several important linguistic features.

产品属性抽取是一个很有价值的研究任务，为了提高评论语料中产品属性抽取的准确率，本文采用条件随机场模型和最大熵模型在产品属性抽取任务中进行比较分析。

Strategy for Mining of Rough Approximation Precision Data Based on Fuzzy Attribute Set

基于模糊属性集的粗糙近似精度数据挖掘策略

The proposed algorithm solved the problem of low efficiency and inferior precision that calculating the similarity only depended on the attribute value and did not consider semantic and attribute type influence in the traditional recommendation algorithm.

对于传统商品购物推荐系统的相似性只单独计算属性值的算法，而不考虑语义和属性类型的影响，效率低，精度差。

Attribute to its advantages of high accuracy, anti-friction, clean and health, aerostatic bearing is widely used in spaceflight, pharmaceuticals industry, food service industry, high precision machine tool and measuring instrument areas.

空气静压轴承以其高精度、低摩擦、无污染的特点广泛应用于航空航天、食品医药以及高精密机床和测量仪器等领域中。

In this system, the neural network nonlinear inversion method is used to interpret thickness variation of coal seam. This method defines the nonlinear relationship of both coal thickness and seismic attribute parameters quantitatively and has high interpretation precision.
