Hybrid Consistency Framework for Distributed Annotation Records
نویسندگان
چکیده
We describe a novel hybrid consistency framework that maintains consistency among Distributed Annotation Records kept at various web-based annotation tools. There are issues in semantics of annotation tools. Each annotation tool stores different metadata, has different rules for tags, and does not provide timing information for the updated records. As a result of these, documents can be updated inconsistently with unknown precise time stamps and spread around in existing annotation tools with different versions. Moreover, their communications with other annotation tools are also very limited through various forms and this also contributes to inconsistencies among Distributed Annotation Records. To deal with these major shortcomings, this paper introduces the notion of “hybrid-consistency framework”, which maintains the consistency among distributed annotation records held at various annotation tools. We discuss the overall design, architecture and the components of the hybrid consistency framework, and provide a working prototype implementation and a roadmap of the future work in this research.

متن کاملDefining Uniform and Hybrid Memory Consistency Models on a Unified Framework
The behavior of Distributed Shared Memory Systems is dictated by the Memory Consistency Model. Several Memory Consistency Models have been proposed in the literature and they fit basically in two categories: uniform and hybrid models. To provide a better understanding on the semantics of the memory models, researchers have proposed formalisms to define them. Unfortunately, most of the work has ...

We introduce CCASH (Cost-Conscious Annotation Supervised by Humans), an extensible web application framework for cost-efficient annotation. CCASH provides a framework in which cost-efficient annotation methods such as Active Learning can be explored via user studies and afterwards applied to large annotation projects. CCASH’s architecture is described as well as the technologies that it is buil...
متن کاملView-based Consistency for Distributed Shared Memory
This paper proposes a novel View-based Consistency model for Distributed Shared Memory. A view is a set of data objects that a processor has the right to access in a data-race-free program. The View-based Consistency model requires that the data objects of a view are updated only before a processor accesses them. Compared with other memory consistency models, the View-based Consistency model ca...
