We describe the error handling architectture underlying the RavenClaw dialog management framework. The architecture provides a robust basis for current and future research in error detection and recovery. Several objectives were pursued in its development: task-independence, ease-ofuse, adaptability and scalability. We describe the key aspects of architectural design which confer these properti...

Error recovery techniques for LR parsers presented in the literature are described and classified. The techniques considered range from the non-correcting ones to interactive and incremental ones. Also, some of the techniques presented are compared and evaluated. An example showing the advantages and the disadvantages of each class of strategies is given and is used as a guideline for classifyi...

Process-aware information systems will be not accepted by users if rigidity or idleness due to failures comes with them. When implementing business processes based on process management technology one fundamental goal is to ensure robustness of the resulting process-aware information system. Meeting this goal becomes extremely complicated if high flexibility demands need to be fulfilled. This p...

The approaches to error handling in two contrasting industrial robot case studies are presented and discussed.

With the growing popularity of the Internet, there is increasing interest in using it for audio and video transmission. Periodic network overloads, leading to bursty packet losses, have always been a key problem for network researchers. In a long-haul, heterogeneous network like the Internet, handling such an error becomes especially difficult. Perceptual studies of audio and video viewing have...

Exception handling has been proven to be the most general fault tolerance technique as it allows effective application-specific recovery. If exception handling is to make programmer’s work more productive and less error-prone, however, it requires adequate support from the programming and execution environments. Scoping is a dynamic structuring technique which makes it easier for the developers...

The IETF developed the RPL routing protocol for Low power and Lossy Networks (LLNs). RPL allows for automated setup and maintenance of the routing tree for a meshed network using a common objective, such as energy preservation or most stable routes. To handle failing nodes and other communication disturbances, RPL includes a number of error correction functions for such situations. These error ...

It has been widely recognized that the testing of Linux kernel is important. However, error handling code is one of the places where testing is difficult. In this paper, a new block I/O test tool is introduced. This makes testing of error handling codes easy. The new test tool has driver level fault injectors which have flexible and fully controllable interface for user level programs to simula...
