    Abstract: In general, in one aspect, a method for managing data in a data storage system includes receiving identifiers corresponding to different respective entries of a map stored in the data storage system, with a particular identifier corresponding to a particular entry of the map, the particular entry including a computed value corresponding to a particular portion of data stored in the data storage system and metadata indicating a location where the particular portion of data is stored in the data storage system, selecting, according to a first selection criterion, at least some of the identifiers for storage in a first portion of an index, and selecting, according to a second selection criterion, at least some of the identifiers for storage in a second portion of the index.

    Abstract: Incremental, out-of-place updates may be implemented for index structures maintained for data stores. Portions of the index structure may be selected for updating, and an updated version of the portion of the index structure generated in another storage location different than a current storage location for the index structure such that the index structure may be searched in order to perform access requests. Updating the portion of the index structure may include compacting the portion of the index structure and/or merging the portion of the index structure with a sub-index structure generated from a portion of a log of index updates that may be maintained. The current portion of the index structure may then be replaced with the updated version of the current portion so that the updated version may be evaluated when searches of the index structure are performed.

    Abstract: A data processor for transferring or maintaining a data sample, includes: a table management unit that manages a data value table that relates a data type of the data sample, usage attribute information defined by a pair of at least one attribute type and a value concerning a utilization form, and information for defining a value index; and a prioritizing unit that defines the value index for the data sample based on the data value table, the value index belonging to a specific data type and associated with the usage attribute information, and sets a priority of the transferring or the maintaining of the data sample using the value index.

    Abstract: A course recommendation system is provided with an on-line social network system. The course recommendation system accesses a target section in an electronic presentation, selects electronic courses that have been identified as associated with one or more skills discussed in the target section and uses an inverted index of skills-to-course mappings to determine, for each such course, a relevance score that reflects how useful the course is for imparting a skill discussed in the target section. A user interface including references to one or more most relevant courses is rendered on a display device of the viewer of the presentation together with the target section.

    Abstract: An apparatus executes preprocessing for an information processing apparatus that maintains a database according to index data having a tree structure, where the tree structure includes plural pieces of node data and plural pieces of edge data linking the plural pieces of node data. The apparatus stores existing index data of the database, and receives input data to be added to the database. The apparatus compares the existing index data with input index data included in the input data, and extracts, from the input index data, new node data indicating a difference between the existing index data and the input index data. The apparatus creates additional index data including new tree data in which pieces of the new node data are continuously arranged, and transmits the additional index data to the information processing apparatus.
