Abstract: A clustering method yields a searchable hierarchy to speed retrieval, and can function dynamically with a changing document population. Nodes of the hierarchy climb up and down the emerging hierarchy based on locally sensed information. Like previous ant clustering algorithms, the inventive process is dynamic, decentralized, and anytime. Unlike them, it yields a hierarchical structure. For simplicity, and reflecting our initial application in the domain of textual information, the items being clustered are documents, but the principles may be applied to any collection of data items.

Abstract: A methodology for semi-automatic unification of models of business processes permits accurate comparison of business processes across government agencies or other organizations despite heterogeneity of language and style in the original models. Input into an algorithm includes a set of models produced by different organizations that describe roughly equivalent business processes (the original models). Output includes a single integrated model in which similarities are made explicit in shared generic layers of the model, while differences are represented in organization-specific layers that inherit from the generic layers (the unified model). Internally, the system represents the original and unified models in description logic using the Web Ontology Language (OWL).

Abstract: A data analysis system with dynamic information extraction and self-organizing evidence construction finds numerous applications in information gathering and analysis, including the extraction of targeted information from voluminous textual resources. One disclosed method involves matching text with a concept map to identify evidence relations, and organizing the evidence relations into one or more evidence structures that represent the ways in which the concept map is instantiated in the evidence relations. The text may be contained in one or more documents in electronic form, and the documents may be indexed on a paragraph level of granularity. The evidence relations may self-organize into the evidence structures, with feedback provided to the user to guide the identification of evidence relations and their self-organization into evidence structures.
