Embodiments of the invention provide a system and method of automatically generating weights for matching data records. Each field of a record may be compared by an exact match and / or close matches and each comparison can result in a mathematical score which is the sum of the field comparisons. To sum up the field scores accurately, the automatic weight generation process comprises an iterative process. In one embodiment, initial weights are computed based upon unmatched-set probabilities and default discrepancy weights associated with attributes in the comparison algorithm. A bulk cross-match is performed across the records using the initial weights and a candidate matched set is computed for updating the discrepancy probabilities. New weights are computed based upon the unmatched probabilities and the updated discrepancy probabilities. Test for convergence between the new weights and the old weights. Repeat with the new weight table until the weights converge to their final value.

The method according to the invention gene rates an aerial image mosaic viewing a larger area than a single image from a camera can provide using a combination of computer vision and photogrammetry. The aerial image mosaic is based on a set of images acquired from a camera. Selective matching and cross matching of consecutive and non-consecutive images, respectively, are performed and three dimensional motion and structure parameters are calculated and implemented on the model to check if the model is stable.

This invention concerns filling vacancies. It may be applied to finding replacements during staff shortages, or to filling entire rosters. It may also be used to fill casually occurring service needs, such as the need-for a child minding placement. The invention involves entering availability details into a candidate data store, and entering vacancy details into a vacancy data store. Automatic cross-matching of each vacancy to availability details create a list of available candidates for each vacancy. Automatically ordering the list for each vacancy ranks the candidates according to predetermined criteria. The vacancies are then filled with the top ranking available candidate. This may be performed automatically or involve the transmission of invitations and acceptances. The invitations may be automatically dispatched, and the responses may automatically update the data. It may be layered to integrate the filling of a vacancy with the provision of a service for a related period of time. For instance, integrating the filling of a teaching or nursing staff vacancy with the provision of child minding services for the same period.
