摘要： A system and method of providing predicted user ratings includes calculating the accuracy of predictions based on the variance of distribution of the predicted user's rating. The system and method present and rank the results by treating the variance as a source of noise. The decision to present or not to present an item is made by sampling the probability distribution of the predicted rating and comparing the result to some user-set threshold (e.g., "show me all results that the system predicts I will score 3 or higher") or a system default value.

摘要： A system and method of predicting a user's rating of a new item in a collaborative filtering system in which an initial set of correlation coefficients for the intended users is used to bootstrap the system is described. The users are members of a predetermined organization and the initial correlation coefficient for each pair of users is based on the organizational relationship between the users. Prior organizational relationship information pertaining to the strength of ties, such as a formal organization chart and social network maps built using interviews or deduced from observed (online and/or off line) interaction patterns between potential users, is used to bootstrap the filtering system. Correlation coefficients can be updated as users rate or rerate items in the system.

摘要： A system for providing item recommendations includes a memory (40), a device (10), responsive to a user request, for recording an item on a hardcopy medium, and a processor (12), for storing ratings of items and for generating recommendations for new items based on recommendation criteria. In response to the user request, the processor (12) stores an implicit rating for the requested item in the memory (40), determines whether, based on the implicit rating and the recommendation criteria, to generate an item recommendation, and if the criteria for generating a recommendation is met, generates a recommendation of a new item. The recommender system may further store a representation of the recorded item in the memory. Recommendations may be based on item to item similarities, item to user similarities or user to user similarities.

摘要： A document recommendation system incorporating a document change monitoring agent (403). For a document recommendation system to be effective, it is desirable to enable users to be cognizant of changes that may occur to the document. The present invention addresses this issue by coupling a document change monitoring agent (403), which automatically detects changes in referenced documents, with a recommender system (401), which helps users share and evaluate information in a collaborative way. One advantage of the invention is that it brings human judgement into the relevance evaluation of the detected changes and allows the results to be shared with other people likely to be interested, in such a way that redundant work is decreased. Another advantage of the invention is that it enables Systems Administrators of a document recommendation system to be more efficient in the management of the system.

摘要： The method of the invention overcomes the problems in a community when the amount of interaction drops off through the use of "community crickets" (46). A community cricket (46) monitors the amount of community activity, establishes criteria for deciding when a community (10) is sleeping and uses that criteria for initiating a recovery mechanism for "re-awakening" the community. A community is "sleeping" if the level of activity falls below some predetermined level or criteria. By monitoring the community's activity, the community cricket can prevent sleeping communities from dying. Various methods to detect and to re-awaken sleeping communities are defined.
