Abstract
Official abstract text for this publication.
Online systems, for example, social networking systems store features describing relations between entities represented in the online system. The information describing the features is represented as a graph. The online system maintains a cumulative feature graph and an incremental feature graph. Feature values based on recent user actions are stored in the incremental graph and feature values based on previous actions are stored in the cumulative graph. Periodically, the information stored in the incremental feature graph is merged with the information stored in the cumulative feature graph. The incremental graph is marked as inactive during the merge and information based on new user actions is stored in an active incremental feature graph. If a request for feature information is received, the feature information obtained from the cumulative feature graph, inactive incremental feature graph and the active incremental feature graph are combined to determine the feature information.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method comprising: accessing a cumulative feature store storing feature values determined from user actions performed before a time point; accessing an incremental feature store storing feature values determined from user actions performed after the time point; calculating, by a computer processor of an online system, a weighted combination of feature values from the incremental feature store and corresponding feature values from…
