Abstract: Embodiments of the present invention are directed to identifying a source of bias in a sample set and using statistical techniques to overcome the bias, thereby producing extrapolated data that accurately represents a population including the sample set. The method according to one embodiment comprises identifying a plurality of attributes corresponding to an entity, generating a plurality of clusters from the plurality of attributes, the plurality of clusters including varying numbers of the plurality of attributes, and performing measurements on each of the plurality of clusters to generate measurement data values for each of the plurality of clusters. A cluster with a greatest measurement data value is selected.

Abstract: A method and apparatus for customizing content presented to individual users or user segments is provided. There may be three components, a web portal and toolbar component, a modeling component, and a scoring component. The web portal and toolbar component presents content items and collects data. The web portal and toolbar component generates user event data based on the user actions. The user event data is forwarded to the modeling component. The modeling component generates content scoring functions based on user event data and attributes of content items. Content scoring functions may be unique to individual user segments. The content scoring functions based on content features generate probability a content item will be viewed. The scoring component decides which content items are placed in a portal. The scoring component uses the scoring functions generated by the modeling component to rank content items in real time.

Abstract: A method selects a predictor item that has a relevance to a user. The method receives a set of affinity items having affinity scores that relate the predictor item to the affinity items. The method filters the list of affinity items based on the affinity scores, and selects a first set of affinity items from the filtered items. For each selected affinity item, the method calculates a difference score from the predictor item, and selects a first affinity item based on the difference score for the first affinity item. Preferably, content is presented to the user based on the selected first affinity item. Additional embodiments include a system and/or computer readable medium having instructions for execution of the foregoing.

Abstract: A method of determining content relevance for a user sets a user preference, which is related to a first area of content. The method calculates a set of scores, by using a combination, of the user preference, affinity data, and a parametric weight. The method organizes the content by using the set of scores, such that the organization of the content has a desirable relationship to the user, and recommends the selected content. Preferably, the method precomputes the affinity data and/or the parametric weight to generate and store the precompiled data for later retrieval. The affinity data describes a relationship between a first item of content and a second item of content, and the parametric weight describes an attribute of the second item. Additional embodiments include a system implementation and computer readable medium.

Abstract: In an embodiment, new traffic pattern data is received pertaining to a first time period having a first time increment. The traffic pattern data may be received as, or converted to, count information reflecting the probabilities that the user will select particular links services. An incremental table is accessed to determine stale traffic pattern count data, which is the traffic pattern count data in the incremental table over a second time period having the first time increment, wherein the second time period covers the oldest traffic pattern count data in the incremental table. Then a count table is updated to reflect removal of the stale traffic pattern count data, wherein the count table contains global count data at a higher level of granularity than the incremental table. The incremental table and count table are updated to reflect addition of the new traffic pattern data.
