  collection selection
Exploiting Manual Indexing to Improve Collection Selection and Retrieval Effectiveness
      
We also show how the use of controlled indexing vocabulary can be employed to achieve performance gains for collection selection.
      
We vary its parameters and compare it to previous collection selection functions, demonstrating a configuration that directs most of the appropriate queries to replicas in a replica hierarchy.
      
Auxiliary viewpoints may also be used for purposes of collection selection.
      
After the training, we perform collection selection as shown in the next section.

It seems very difficult to assess the farmland fertility quality generally and objectively, because of influences from both natural and human factors. In order to avoid the subjectivity in the evaluation processes, some mathematical methods were introduced to this field in recent years, with which the numerical evaluation can be conducted.

It seems very difficult to assess the farmland fertility quality generally and objectively, because of influences from both natural and human factors. In order to avoid the subjectivity in the evaluation processes, some mathematical methods were introduced to this field in recent years, with which the numerical evaluation can be conducted. This paper introduced and compared several evaluation methods of farmland fertility. At the same time, it has introduced the sampling techniques, minimum database systems of evaluation indicators, and numerical methods of integrated evaluation in detail. With the development of GPS and GIS, the evaluation methods of soil fertility quality will be more perfect, which provide theoretical basis for the rational use of soil resources.

农田土壤肥力受自然因素和人为因素的双重影响 ,对其进行客观的综合评价显得非常困难 ,为了在对农田土壤肥力综合评价过程中尽量避免主观性 ,减少人为因素 ,人们更多地采用一些数学方法参与到评价过程中 ,进行数值化综合评价。本文就目前流行的有关土壤肥力综合评价的方法进行了介绍和比较 ,并对其取样技术、评价指标最小数据集的选择以及数值化综合评价方法进行了详细介绍。随着GPS、GIS技术的发展 ,土壤肥力质量评价系统会日臻完善 ,为土壤资源的合理利用提供依据。

This paper proposes an improved decision tree method for Web information retrieval with self-map attributes.The self-map tree has a value of self-map attribute in its internal node based on dissimilarity between a pair of map sequences.The method selects self-map which exists between data by exhaustive search based on relation and attribute information.Experimental results confirm that the improved method constructs comprehensive and accurate decision tree.Moreover,an example shows that the self-map decision...

论文讨论了Web信息的自映射空间模型和决策树算法的实现。从应用角度提出一种新的决策树方法SMS-DT,并根据映射序列的不同在内节点得到唯一的映射属性值。在关系和属性信息的基础上,自映射由不同数据集选择合理的空间模型,得到有效的决策树映射方法。实验结果进一步证实自映射决策树具有全面性与精确性。由于自映射决策树较好地软化了数量属性论域的划分边界,从而为进一步满足Web信息检索提供了一种个性化的高效信息检索工具。
