A high-performance interpretive approach to schema-directed parsing
2007
Proceedings of the 16th international conference on World Wide Web - WWW '07
Preserved Fulltext
Our approach is demonstrated with a specialized schema compiler, used to generate bytecodes which in turn drive an interpretive parser. ...
As XML has become a performance-critical aspect of the next generation of business computing infrastructure, however, it has become increasingly clear that XML parsing often carries a heavy performance ...
ACKNOWLEDGMENTS Joe Latone managed this project and contributed to it greatly. We would also like to thank Joe Kesselman, David Marston, Chet Murthy, Dennis Quan, and many others. ...

This paper presents a high-performance XML parsing and validation technique that is time and space optimal. ...
The schema validity constraints are packed in a compact parsing table derived from a permutation phrase grammar. ...
More recent work that builds on XML Screamer is iScreamer [11] . iScreamer is a schema-directed interpretive XML parser and achieves high-performance gains by using a carefully tuned set of special-purpose ...

We show how the unification-based approach can be scaled up to provide a full multimodal grammar formalism. ...
Integration strategies are stated in a high level unificationbased rule formalism supporting rapid prototyping and iterative development of multimodal systems. ...
Our approach differs in that, given the nature of the input, using spatial constraints and top-down predictive information to guide the parse is less of a concern, and as a result the parsing algorithm ...

To surpass existing heuristics, there is a need for a formal basis, which is realized in this paper through the framework of a search database system, where an interpretation is identified as a parse. ...
The difficulty is to translate abstract notions like concept and interpretation into a concrete search algorithm that operates over the auxiliary database. ...
In contrast to other published solutions, our approach is direct in the sense that we actually apply a preprocessing step that suggests interpretations of the query. ...
