Abstract: A subject property and a corresponding updatable pool of property sales are displayed in a map image. Property characteristics that define the pool of recent sales are manipulated using an interface that lists the characteristics and provides updatable ranges. Once a satisfactory set of ranges is established, the corresponding sub-market for the subject property is recalculated using only those properties that satisfy the new property characteristics criteria. A map image automatically updates to show those properties included in the updated pool, and those that were excluded. A model-based valuation also automatically updates and is listed among property data for the subject property.

Abstract: Method and computer program products for implementing an identity control system are disclosed. Documents are abstracted by mapping non-identifying words in the documents to non-identifying concepts that are designated by codes, which codes are linked to non-identifying descriptions and may optionally non-identifying values. Similarly, identifying words in the documents are abstracted by mapping identifying and/or potentially identifying words in the documents to identifying concepts that are designated by codes, which codes are themselves non-identifying and have non-identifying descriptions and may optionally have values, which values may be identifying or may be obfuscations of the identifying information. Non-identifying codes and optional values, the words that are mapped to those codes and stop-words are indexed as non-identifying index data. Identifying codes and optional values, and the words that are mapped to those codes are indexed as identifying index data.
