查询词典 attribute

The traditional distinction based on the matrix attribute reduction algorithm analysis, for distinction in the matrix "repeat" Too many elements, these "duplicate" elements not only in solving attribute reduction in the process does not work, But also reduce the time efficiency by improving the shortcomings that distinction in the matrix structure in the process of using Proposition calculus in the absorption of the law removed the distinction between the functions of the non-functional "repeat"element, a property Reduction of improved algorithm RADM, improve the efficiency of the attribute reduction.

通过对传统的基于区分矩阵的属性约简算法进行分析后，针对区分矩阵中"重复"元素过多，同时这些"重复"元素非但在求解属性约简的过程中不起作用，而且还降低时间效率这一缺点进行了改进，即在构造区分矩阵的过程中，利用命题演算中的吸收律去掉了在区分函数中不起作用的"重复"元素，提出了一种属性约简的改进算法RADM，提高了属性约简效率。

In GIS, data quality is one of the key aspects.The Recent studies of data quality in GIS most focus in the error of spatial data. The error study on attribute data is very weak. Most studies centralize in precision analysis of attribute data from remote sensing and introduction of new method. The studies of attribute information quality stored in RDB are very weak.

近年来，GIS数据质量的研究集中在位置数据的误差上，而对属性数据误差的研究较少，多年来的研究主要集中在遥感分类属性数据的精度分析和一些新方法的引入上，而关系数据库存储的属性信息质量方面的研究相对比较薄弱。

If the value of the 'to' attribute is invalid or cannot be contacted, the entity discovering that fact (usually the sender's or recipient's server) MUST return an appropriate error to the sender, setting the 'from' attribute of the error stanza to the value provided in the 'to' attribute of the offending stanza.

如果"to"属性值不无效或不能连接的，发现这个情况的实体(通常是发送者或接收者的服务器)必须返回一个适当的错误给发送者，将这个错误的stanza的"to"属性值设置在这个错误返回的stanza的"from"属性值。

In this paper, each of single data stream that is included in data streams has same attributes set as other,the unit of single data stream is tuple,and same attributes set is included in each of these tuples.Reservoir algorithm is used to sample from these single data stream respectively,then some multiple snapshot windows are constructed,the relationship between these single data stream and multiple snapshot windows is bijective mapping,the relationship between attributes that are included in tuple and snapshot windows that are included in relative multiple snapshot windows is bijective mapping,and the relationship between basic windows that belong to same snapshot window and the attribute values that come from different single data stream is bijective mapping as well,that is,these attribute values come from same attribute that is comprised by different single data stream.

针对以元组为单位流入的具有相同属性集的多支单数据流组成的多数据流，提出了分别对每支单数据流进行蓄水池抽样，构造一一对应于各单数据流的若干个多快照窗口，即两者之间是双射关系，可以将多快照窗口串行置于主存中，将元组包含的属性与多快照窗口中的各个快照窗口一一对应，且使得同一快照窗口中的各基本窗口与取自其对应的单数据流的属性值样本一一对应，然后对这些相互独立的样本进行方差分析。

In this paper,with respect to the ordinal variables,the definitions of attribute reduction of dominance-based rough set approach in ordered information systems and ordered decision tables are given.Then the approach of sorting objects comprehensively using rough set theory is brought in to obtain a series of ranks.Based on these ranks,nonparametric methods to analyze correlation between two attribute subsets are introduced,and Spearman rank correlation coefficient is used as a measure of attribute correlation.Based on this measure,a new method of attribute reduction of ordered information systems and ordered decision tables is presented without changing the ordinal information of the universe.

针对有序尺度变量，给出了有序信息系统与有序决策表在优势关系下的粗糙集约简定义；利用粗糙集方法将对象综合排序，进而得到一组秩；根据这些秩，运用非参数统计的思想研究了两个属性子集之间的相关性，并将Spearman秩相关系数作为属性相关性度量；在不改变总体序信息情况下，给出了基于此度量对有序信息系统与有序决策表进行约简的新方法。

The objective substantialism is good at analysis of the endogensis and objective attribute of the nation, but ignores the subjective attribute of nation, and other and relation for the forming of nation-self. The subjective substantialism focuses on the subjective attribute of nation. In the theory, the attribute is amplified that it is struck in the rut of defining the term nation using the relation between the nation and nationalism.

前者长于民族的客观属性分析与内生分析，但忽略了民族的主观属性，忽略了他者和关系对民族自我的塑造作用；后者最为看重民族的主观属性，强调民族主义对民族的塑造作用，但放大了民族的主观属性，且落入从民族主义与民族两者的关系来界定民族的案臼。

For single-attribute range queries in Armada, this thesis designs the single-attribute order-preserving naming algorithm Single_hash to assign adjoining ObjectIDs to objects with close attribute values based on the partition tree model, so that the objects can be published to the same or related peers in the P2P system. Then this thesis proposes the single-attribute range query processing algorithm PIRA, which can match the search paths of range queries to the underlying FissionE topology efficiently based on the forward routing tree to reduce the delay and message cost of range queries.

为实现Armada单属性区间搜索，本文首先提出基于分区树的单属性维序命名算法Single_hash，使得属性值接近的资源对象能够获得相近的标识，以发布到相同或相关的结点上；然后提出基于前向路由树的单属性区间搜索算法PIRA，实现了区间搜索路径与底层FissionE拓扑的高效匹配，以有效降低区间搜索延迟，减少搜索消息开销。

So the twenty-three feature variables have been partitioned four classes which contain continuous attribute, integer attribute, nominal attribute and dimidiate attribute.

将变量分为连续型、有序型、标称型、二分型四类23种。

The positive region based on radix sorting is used to get the positive region condition attributes set of decision attributes and the condition attribute set which excludes one of the condition attributes of decision attribute positive region. Then the difference between the two radices of positive regions is calculated to judge whether the condition attribute is a core attribute, thereby all the condition attributes are judged and the required core is quickly acquired.

采用基数排序思想计算正区域，分别得到决策属性正区域的条件属性集和除决策属性正区域的一个条件属性之外的条件属性集，并且计算这2种属性集的基数之差，以判断该条件属性是否是核属性，依次判断所有条件属性，从而快速获得所需要的核。
