Abstract: A system, method, and apparatus are provided for indexing and sequentially storing variable-length data in a manner that facilitates reverse reading. Each entry stored in a log file, database, or other repository includes a data record having a fixed number of keys, a key offset corresponding to each key, and size metadata identifying a size of the data record (and possibly the key offsets). Each key offset is an offset to another entry (e.g., the matching key offset of the entry) whose data record features the same value for the corresponding key. An index identifies, for each given value of each key, an index offset to a first entry (e.g., the most recently stored entry) that has the given value for that key. Retrieving records matching a particular key value therefore simply involves following the corresponding index offset and then some number of key offsets.

Abstract: A system, apparatus, and method are provided for implementing secondary profiles for members of an online application or service.

Each fact or entry in the secondary (or inferred) profile is accompanied by a confidence score reflecting confidence in the source of the fact, confidence that the fact is correctly associated with this member, and/or other factors. A given fact may be obtained or extracted from multiple sources, with each copy or version assigned a separate confidence score. In response to a request to identify members having a particular attribute, in addition to identifying members that have the attribute in their primary profiles, members having the attribute in their secondary profiles may be identified if the corresponding confidence scores are greater than a threshold.

Abstract: A system, method, and apparatus are provided for distributing a content item toward target recipients solely via first degree connections (e.g., in a professional network, in a social network).
