A system, method, and apparatus are provided for selecting electronic content to surface to a member of a user community, among content associated with a second member with whom an inferred (i.e., non-explicit) connection has been formed. Based on the members' types (e.g., Professional, Student, Recruiter) and/or other factors, a type is assigned to the new connection. A default vector comprising weights corresponding to multiple categories of content that may be served to a community member (e.g., content creation items, content curation items) is generated based on how other members within the same type of relationship interacted with content surfaced to them. A personal vector copied from the default vector is used to select, from content associated with the second member, items to surface to the first member, but may be altered over time based on the first member's interaction with the items.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method comprising: establishing a new inferred connection between a first member and a second member of an online user community; characterizing the new connection as being of a first connection type, based on a first member type of the first member and a second member type of the second member; based on the first connection type, obtaining an associated vector comprising weights corresponding to multiple content categories; when selecting electronic content to offer the first member, selecting content items associated with the second member based on the vector; and serving to the first member one or more content items associated with the second member. 2. The method of claim 1, further comprising, prior to establishing the new inferred connection: characterizing the first member and the second member with the first member type and the second member type, respectively; identifying interaction by the first member with a first content item associated with the second member, wherein the first content item belongs to a first content category among the multiple content categories; and determining that no explicit member connection exists between the first and second members within the user community. 3. The method of claim 2, wherein a given member is characterized with a given member type based on profile attributes of the given member within the user community, including one or more of: job; title; functional area; industry; and employer. 4. The method of claim 1, wherein obtaining the vector associated with the first connection type comprises: identifying a plurality of connections of the first connection type within the user community, excluding the new connection, each identified connection involving another first member and a corresponding other second member; recording each other first member's interaction with content items associated with the corresponding other second member; for each content item with which at least one other first member interacted, calculating a value of the content item to each other first member that interacted with the content item; for each content category, aggregating calculated values of content items within the content category to produce a content category weight; and assembling the vector to comprise the content category weights for the multiple content categories. 5. The method of claim 4, wherein calculating a value of a given content item to a given other first member comprises: for each of multiple possible interactions of the given other first member with the given content item: determining a value of the interaction, based on whether the interaction occurred; determining a weight associated with the interaction; and calculating a product of the interaction value and the associated weight; and aggregating the calculated products to yield the value of the given content item to the given other first member. 6. The method of claim 1, further comprising, after serving to the first member multiple content items associated with the second member: analyzing the first member's interaction with the multiple content items; and adjusting one or more content category weights within the vector, based on the first member interaction with the multiple content items, to yield an adjusted vector. 7. The method of claim 6, further comprising: re-characterizing the new connection as being of a second connection type instead of the first connection type, based on one or more of: variance of the adjusted vector from a default form of the vector associated with the first connection type; and modification of user community profiles of one or both of the first member and the second member. 8. The method of claim 1, wherein the multiple content categories include: content creation; content curation; content consumption; and profile updates. 9. The method of claim 1, wherein: member types comprise: professional; professor; recruiter; sales; student; thought leader; and public face; and connection types comprise: colleague; competitor; mentor; poaching; and business partner. 10. An apparatus, comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the apparatus to: establish a new inferred connection between a first member and a second member of an online user community; characterize the new connection as being of a first connection type, based on a first member type of the first member and a second member type of the second member; based on the first connection type, obtain an associated vector comprising weights corresponding to multiple content categories; when selecting electronic content to offer the first member, select content items associated with the second member based on the vector; and serve to the first member one or more content items associated with the second member. 11. The apparatus of claim 10, wherein the memory further stores instructions that, when executed by the one or more processors, cause the apparatus to, prior to establishing the new inferred connection: characterize the first member and the second member with the first member type and the second member type, respectively; identify interaction by the first member with a first content item associated with the second member, wherein the first content item belongs to a first content category among the multiple content categories; and determine that no explicit member connection exists between the first and second members within the user community. 12. The apparatus of claim 11, wherein a given member is characterized with a given member type based on profile attributes of the given member within the user community, including one or more of: job; title; functional area; industry; and employer. 13. The apparatus of claim 10, wherein obtaining the vector associated with the first connection type comprises: identifying a plurality of connections of the first connection type within the user community, excluding the new connection, each identified connection involving another first member and a corresponding other second member; recording each other first member's interaction with content items associated with the corresponding other second member; for each content item with which at least one other first member interacted, calculating a value of the content item to each other first member that interacted with the content item; for each content category, aggregating calculated values of content items within the content category to produce a content category weight; and assembling the vector to comprise the content category weights for the multiple content categories. 14. The apparatus of claim 13, wherein calculating a value of a given content item to a given other first member comprises: for each of multiple possible interactions of the given other first member with the given content item: determining a value of the interaction, based on whether the interaction occurred; determining a weight associated with the interaction; and calculating a product of the interaction value and the associated weight; and aggregating the calculated products to yield the value of the given content item to the given other first member. 15. The apparatus of claim 10, further comprising, after serving to the first member multiple content items associated with the second member: analyzing the first member's interaction with the multiple content items; and adjusting one or more content category weights within the vector, based on the first member interaction with the multiple content items, to yield an adjusted vector. 16. The apparatus of claim 15, wherein the memory further stores instructions that, when executed by the one or more processors, cause the apparatus to: re-characterize the new connection as being of a second connection type instead of the first connection type, based on one or more of: variance of the adjusted vector from a default form of the vector associated with the first connection type; and modification of user community profiles of one or both of the first member and the second member. 17. The apparatus of claim 10, wherein the multiple content categories include: content creation; content curation; content consumption; and profile updates. 18. A system, comprising: one or more processors; and a connection inference module comprising a non-transitory computer-readable medium storing instructions that, when executed, cause the system to: establish a new inferred connection between a first member and a second member of an online user community; a characterization module comprising a non-transitory computer-readable medium storing instructions that, when executed, cause the system to: characterize the new connection as being of a first connection type, based on a first member type of the first member and a second member type of the second member; and a recommendation module comprising a non-transitory computer-readable medium storing instructions that, when executed, cause the system to: based on the first connection type, obtain an associated vector comprising weights corresponding to multiple content categories; when selecting electronic content to offer the first member, select content items associated with the second member based on the vector; and cause to be served to the first member one or more content items associated with the second member. 19.
