Software refactoring is to improve readability, maintainability and expansibility of software by adjusting its internal structure, whereas the external behaviors of software are not changed. Although software refactoring should not change the external behaviors of software systems, they might make a regression test case obsolete (with syntax and runtime errors) or fail. People have investigated which...
With the advent of the Web of Linked Data, new challenges to federated query processing are emerging. Different from traditional federated database systems which do static data integration, this Web of Data is open and ever-changing. In this paper, we present a agent-based architecture providing a flexible and decoupled solution for the federated queries over Linked Data. Based on the presented architecture,...
Long and complex methods are hard to read or maintain, and thus usually treated as bad smells, known as Long Method. On the contrary, short and well-named methods are much easier to read, maintain, and extend. In order to divide long methods into short ones, refactoring Extract Method was proposed and has been widely used. However, extracting methods manually is time consuming and error prone. Though...
Search results clustering aims to facilitate users' information retrieval process and query refinement by online grouping similar documents returned from the search engine. It has stringent requirements on performance and meaningful cluster labels. Thus, most existing clustering algorithms such as K-means and agglomerative hierarchical clustering cannot be directly applied to the task of online search...
