The High Performance Knowledge Bases program is developing a software system that helps human information providers attach English phrases and sentences as content-describing "annotations" to text segments, images, diagrams, data sets and other varieties of information. This system, called HAWK, works with human information providers to refine and test annotations of information content, so that the annotated material can be subsequently retrieved through a process of matching annotations to English queries submitted by human information seekers.
The High Performance Knowledge Bases program has constructed a language-based software system that coordinates the indexing and retrieval of multi-media documents associated with crisis understanding situations. The system, called HAWK, helps human information providers attach content-describing "annotations" to text segments, images, diagrams, data sets and other varieties of information, then retrieves those documents by matching the annotations to English queries submitted by human information seekers. The HAWK system has been demonstrated on a test set of 1,000 documents annotated by 20 human information providers.
