Abstract: Methods and systems that improve the ability of a media guidance application to aggregate information from one or more sources and one or more mediums. For example, the media guidance application may automatically collect information based on attributes associated with information of a particular type. Specifically, the media guidance application may determine based on comparison with verified training data that one source or medium typically associates information of a particular type, for example, “Actor,” with one or more path attributes, for example, a location in a directory structure. The media guidance application may then search the source or medium for the one or more path attributes. Upon detecting the one or more path attributes, the media guidance application may designate any sub-set of information associated with the one or more path attributes as a particular type of information.

Abstract: A database management system (DBMS) run a host CPU and a hardware coprocessor accelerate traversal of a tree-type data structure by allocating reusable memory in cache to store portions of the tree-type data structure as the tree-type data structure is being requested by the host CPU. The hardware coprocessor manages the cached tree-type data structure in a manner that is transparent to the host CPU. A driver located at the host CPU or at a separate computing device can provide an interface between the host CPU and the hardware coprocessor, thus reducing communications between the host CPU and the hardware coprocessor.

Abstract: There is provided, in accordance with some embodiments, a method for receiving electronic documents representing a dependency graph comprising feature extractors at each graph node and directed edges corresponding to computational dependencies of the feature extractors. For at least some feature extractors, extractor defining data, comprising extractor data and computational dependencies of the graph node in the dependency graph are determined, and a node lookup key based on the extractor defining data is computed. When the node lookup key is associated with a stored set of output feature values, the stored set is assigned as output values of the feature extractor. When node lookup key is not associated with a stored set of output feature values, a new set of output feature values is computed, stored, and associated the node lookup key. The one set of output feature values are sent as an output feature set.

In one example, a method may include calculating changes to modeled objects in a virtual environment. The modeled objects and the modifications may be stored in a server data store. Modeled objects in the server data store for which the modifications have been received may be flagged and queued for replication of the modifications to the modeled objects from the server data store to a non-transactional data store. The modifications may be replicated by copying modeled object state data from the server data store to the non-transactional data store.

Abstract: An on-line social network system is configured to generate a news feed for a member by processing updates originating from different sources using different first pass ranker models. The first pass ranker models generate respective sets of raw scores, which are calibrated based on a consistent scale of feed engagement metrics of interest, such as a click through rate. The calibrated scores are then used as training data to train a second pass ranker and/or as input into the second pass ranker at the time when the second pass ranker is to generate respective ranks for items in an inventory of updates identified as potentially of interest to a focus member and to select a subset of items from the inventory based on the generated respective ranks.

Abstract: Described are techniques for outputting or suppressing output of network content to a user device based on content previously accessed by the user device. Correspondence between network content accessed by the user device and spoiler data determined from media content may indicate that the network content is associated with the media content. Content consumption data associated with the user device may indicate whether the user device has previously accessed the media content. The network content may be suppressed from output if the user device has not previously accessed the media content. The network content may be output to the user device if the media content has been accessed.

Abstract: A system, method, and computer readable medium for removing credit card numbers from a financial transaction record is provided. A temporary record containing only numeric characters is generated by parsing non-numeric characters from the financial transaction record. Numeric strings are then parsed from the temporary record and evaluated to determine if the parsed numeric strings potentially comprise a credit card number. Numeric strings that are evaluated as potentially comprising credit card numbers may then be further evaluated to determine if the numeric strings comprise valid credit card numbers. The original financial transaction record may then be searched for numeric strings evaluated as valid credit card numbers. Any string of consecutive characters that match a validated credit card number may then be replaced with white space characters or other innocuous characters in the transaction record.
