In this paper, a semantic processing method to improve a query-based approach for mining concept maps repositories is proposed. The method is based on a mechanism of semantic extension of the represented concept
To find more likely answers to a given query, they propose a method to measure the matching strength of each tuple as an answer to the query. How to assess the matching strength of each tuple as an answer to the given query is a fundamental issue of querying fuzzy relational databases. ...
If a table is very small, table scans might be the most efficient method for almost all access to the table. The methods used to compute calculations, and how to filter, aggregate, and sort data from each table. As data is accessed from tables, there are different methods to perform ...
If the computation time for using this method is too expensive, consider using Collect instead. Example: >>> u = Zipcode.objects.aggregate(Union(poly)) # This may take a long time. >>> u = Zipcode.objects.filter(poly__within=bbox).aggregate(Union(poly)) # A more sensible approach. ...
Section 3 presents our approach to query term re-weighting in detail. Section 4 reports our results, i.e., Section 4.1 explains our experimental setup, Sections 4.2 and 4.3 present our results in English and Persian data sets, and Section 4.4 discusses the method. Finally, Section 5 ...
CPU Analysis In the first part, we see the performance graphs; the first line is system metrics which show utilization and saturation (as in Brendan Gregg’sUSE Method). Additionally, to overall CPU, I also included the information about max core utilization, which is rather important for MySQL...
First, add a helper method that checks the result of a try operation for a folding error. Power Query M Copy // Returns true if there is a folding error, or the original record (for logging purposes) if not. Test.IsFoldingError = (tryResult as record) => if ( tryResult[HasError...
You do not have to try this approach with queries that contain the IN subquery clause. For example, to determine all the orders that have at least one item with a 25 percent discount or more, you can use the following EXISTS subquery: SELECT "Order ID" FROM Orders O WHERE EXISTS (...
When using theQueryBuilder#storeQuerymethod, the givenQueryis stored into the repository as a file or as a property according to thecreateFileargument value. The following example shows how to save aQueryto the path/mypath/getfilesas a file: ...
1) approximate query method 近似查询方法 2) approximate query 近似查询 1. Anapproximate queryalgorithm based on eight-neighbor grid clustering for heterogeneous XML documents is proposed. 提出了一种基于八邻域网格聚类的多样性XML近似查询算法。
