Title
Qanda and the Catalyst Architecture.
Abstract
Catalyst annotations are standoff (versus inline) which means that the underlying signal is unmodified and anno- tations are maintained and communicated separate from the signal. By separating the signal from the annotations and an- notations of different types from each other, Catalyst is able to automatically construct customized streams of annotation for each component in a system. The set of annotations, attributes and their names can all be transparently modified between each language processing component without mod- ifying any component code or inserting additional scripts. Every standoff annotation has an annotation type identi- fier, a start position, an end position, and zero or more at- tributes. The attributes are named fields that provide infor- mation derived from or associated with the annotated text. For example, a tokenizer might emit word annotations, with text, stem and part-of-speech attributes. The start and end of each such annotation would indicate where in the text the tokenizer found the words.
