自底向上策略
Examples
- Secondly , a database - populating mechanism is built , along with some object - manipulating operations needed for flexible database design , to support data extraction from huge text stream . thirdly , top - down and bottom - up strategies are combined to design a new extraction algorithm that can extract data from data sources with optional , unordered , nested , and or noisy components
本文采用关系数据库来组装抽取对象，给出了将任何ere de -树映射成关系数据库模式的算法，这一数据库映射机制不仅能够支持海量文本流的数据抽取，还支持合并键定义等抽取对象控制操作，可实现灵活的数据库模式设计和数据抽取。 - This paper presents an approach to perceptually extract multi - oriented text lines from online handwriting . the approach adopts a bottom - up strategy . by the approach , strokes are first merged into blocks analogous to words , then a link model is constructed upon these blocks . finally , the optimal text line layout is found out by a branch - bound search on the link model . the experimental results show that the approach is effective and also available to extract curved text lines
提出一种多方向手写笔迹文本行的提取方法.该方法以视觉感知理论为基础,采取自底向上的策略,先将笔画组合成类比字符的笔画块,然后基于这些笔画块建立链接模型,最后采用分支限界搜索算法从链接模型中找出最优行排列.实验结果表明,该方法能有效地提取多方向笔迹行结构,并适用于弯曲文本行的提取
