Precipitation/dissolution of stored programs and segments
View Patent ↗A content maintenance system uses a time-dependent precipitation function for iteratively augmenting or removing content over time, after an initial demonstration of user interest. A plurality of parallel precipitation processes can be launched simultaneously in response to different facets of a user expression of interest. Precipitation is dependent on highlighting or extracting segment descriptors from content of interest to the user. Then segments are filtered, rated, annotated and/or prioritized from that content. The remaining segments are matched against stored search structures. When the segments match, they are precipitated out for storage and can generate new search structures.
1. A method of maintaining and updating stored information comprising executing the following operations in at least one data processing device:
maintaining the stored information as a pool of information potentially of interest to a user;
maintaining a user preference information relating to the pool;
repeatedly
identifying a precipitated information for addition to or deletion from the pool, in accordance with at least
the user preference information, and
a time-dependent precipitation function where the amount of precipitated information identified and added to the pool for a particular query is time-dependent,
adding or deleting the precipitated information responsive to said identifying.
2. The method of claim 1 , wherein identifying precipitated information for addition to the pool is further responsive to content already in the pool.
3. The method of claim 1 , wherein the time-dependent precipitation function specifies an augmentation curve for time-dependent iterative augmentation of precipitated information in response to an initial demonstration of interest by the user.
4. The method of claim 1 , wherein the time-dependent precipitation function specifies a dissolution curve for time-dependent iterative dissolution of precipitated information at a given time after an initial demonstration of interest by the user.
5. The method of claim 1 , wherein precipitated information is used to generate search structures for matching against future received content.
6. A database embodied in a computer readable medium and produced by at least one data processing device in accordance with the method of claim 1 .

repeatedly
identifying a precipitated information for addition to or deletion from the pool, in accordance with at least
the user preference information, and
a time-dependent precipitation function where the amount of precipitated information identified and added to the pool for a particular query is time-dependent,
