Abstract: A database system optimizes database queries that comprise subqueries. The database system factors out computation from two or more subqueries to a reusable subquery. The reusable subquery returns a result set. The subqueries are rewritten to use the result set and the database query modified to use the rewritten subqueries. The modified database query performs efficiently since the result set is computed only once for each subquery that uses the reusable query. The database system also composes nested subqueries that compute aggregate values. The database system identifies an inner subquery nested within an outer subquery, each subquery computing an aggregate value. The database system determines a new aggregate function corresponding to a composition of aggregate functions of the inner and the outer queries. The database system determines a composed query using the inner query with the outer query. The composed query uses the new aggregate function.

Abstract: A process for generating social recommendations is provided. For each user, a user profile index is accessed to determine reading interests of the user. Further, relevance matching is performed to determine matching users having at least one publishing interest that is relevant to the reading interests of the user. Next, the matching users are ranked. Based on the ranking, one or more top ranked matching user(s) are determined. Additionally, a social recommendation for each of the top ranked matching user(s) is enabled to be made to the user.

Abstract: Methods, systems, and computer programs are presented for processing data to control display of followers of an entity to viewers of an entity page of the entity in a social network. One method includes detecting a request to view the entity page by a viewer. Fetching a first row of data associated with the social network. The method processes the first row of data to read a set of bits to determine whether certain ones of the users that are following the entity are to be displayed as following the entity in the entity page. The method also fetches a second row of data to determine whether the viewer is in one of the groups of the users that are following the entity and not displaying the users that follow the entity to the viewer when the viewer is not in one of the groups.

Abstract: Systems and methods are provided for determining mutation regions for a spreadsheet. Mutation regions are iteratively assigned to a first region of cells in the spreadsheet. To assign a mutation region, a column is selected from the first region. A first row in the first region of cells is associated with the selected column that is not assigned to a mutation region and that is not included in a second region of the spreadsheet is determined. A largest region contained within the first region that does not overlap with the second region for which the cell in the selected column and the first row is in a designated position is determined. The largest region is assigned as a mutation region for the spreadsheet.

Abstract: A system and method identifies a video file in response to a video based search query. A video imaging device in a mobile device captures a video file, and sends the video file to a search engine. A database associated with the search engine stores pre-indexed metadata of pre-indexed frames of video. A video analyzer separates the received video file into individual frames, analyzes the individual frames received from the mobile device by converting the individual frames into metadata, and compares the metadata to the pre-indexed metadata of the pre-indexed frames stored in the database. The video analyzer then sends a message containing information about the identified pre-existing video back to the mobile device based on the comparison of metadata. The metadata of the file and/or the metadata in the database may include one or more of pixel information, histogram information, image recognition information and audio information for each individual frame.

Abstract: Renamed directory handling for incremental file migration is described. A directory is stored in a storage device.
