A new semi-supervised approach for Chinese relation extraction (RE) over constantly growing and edgeless web data is introduced in this paper. Existing semi-supervised approaches have the better improvement potential while lacking syntactic structure and semantic meaning of a sentence and unsuitable to loosely structured Chinese sentences. To follow their basic procedures as well as covering their...
Insight Externalization (IE) refers to the process of capturing and recording the semantics of insights in decision making and problem solving. To reduce human effort, Automated Insight Externalization (AIE) is desired. Most existing IE approaches achieve automation by capturing events (e.g., clicks and key presses) or actions (e.g., panning and zooming). In this paper, we propose a novel AIE approach...
Newdle is a visual-analytics system for exploring tagged online news collections. Newdle automatically constructs an article network and article-tag network for a collection and conducts clustering and path analyses on them. Using the analysis results, the system builds visualizations and supports user interaction with the networks. A topic overview lets users grasp a large collection's contents at...
In this paper, we present the formal semantics of sequence diagrams. The semantics of a sequence diagram is interpreted as a consecutive execution of steps in UTP. The semantics clearly captures the consistency between the design class diagram and sequence diagrams. This may underpin development of model consistency checking functions in UML CASE tools. It may also be used to reason about the correctness...
