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...
Design pattern is a way of solution building on the common or recurring problems in software design, which can be combined with Unified Modeling Language (UML) to create a system framework. The UML is a semi-formal language which semantic part is described by natural language. So it will produce semantic inconsistency problem in the modeling process. Therefore, this paper proposes an object called...
Asynchronous Collaborative Visual Analytics (ACVA) leverages group sensemaking by releasing the constraints on when, where, and who works collaboratively. A significant task to be addressed before ACVA can reach its full potential is effective common ground construction, namely the process in which users evaluate insights from individual work to develop a shared understanding of insights and collectively...
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...
Agile software development is a kind of lightweight development method, which can satisfy to the changes of requirements. This paper applies formal methods into agile software development, and investigates the method to adopt the rCOS in agile software development through convincing examples to improve software trustworthiness.
In order to solve the problems of verifying the inconsistency of the requirement specification in the natural language, and automatically transforming the requirement specification in natural language description to formal models, this paper proposes a modeling method of use case specification in XML and a method of verifying inconsistency in the specification. Furthermore, we design a corresponding...
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...
