Previous work on the use of the Teleo-Reactive technique in high level software development has shown it to be a viable approach for autonomic systems. A T-R program can recover from unexpected events without knowing the underlying source or cause of the problem and thus reduces the maintenance costs of software projects where unexpected events are a likely and frequent occurrence. Previous work has...
Guided-based systems are an alternative to natural language systems regarding the query construction method. We present a new solution that bridges the gap between these two types of systems by providing a hybrid interface which combines a graphical query interface for query construction with the correspondent natural language expression automatically generated by the system.
Semantic search importance is growing each day as millions of people around the world need to obtain objective and concrete information. Guided-based systems are an alternative to natural language systems regarding the query construction method. However, current guided-based systems perform query validation only at a syntactical level. In this paper we address the semantic validation of queries in...
Mining web access sequences can discover very useful knowledge from web logs with broad applications. By considering non-binary occurrences of web pages as internal utilities in web access sequences, e.g., time spent by each user in a web page, more realistic information can be extracted. However, the existing utility-based approach has many limitations such as considering only forward references...
