Abstract: While receiving a user input of content of a first document, a computer system, dynamically and in real time, identifies relevant information items from a plurality of information feeds. Specifically, one or more other documents is obtained in a collection of documents that are relevant to the first document being entered by a user. When it is determined that changes in member documents of the set of one or other documents satisfies a stabilization criterion while receiving the user input, related terms are extracted from the content of the first document and the one or more other documents and used to identify the relevant information items including the related terms from the plurality of information feeds that is distinct from the collection of documents. The relevant information items are then presented on a display for the user.

Abstract: Methods, systems, and computer programs are presented for reducing latency for providing a user feed containing one or more posts. One method includes operations for receiving a request to access the user feed and for performing a first query to search posts. The first query uses a first time horizon delimiting a creation time of posts and a first maximum number of posts selected for ranking. The posts from the first query are sent to the client device for presentation on a user interface. Further, a second query is performed to search posts, where the second query uses a second time horizon that is greater than the first time horizon and a second maximum number of posts for ranking that is greater than the first maximum number of posts. The posts from the first query and the second query are merged and sent to the client device for presentation.

Abstract: A method of accelerating transactions for a relational database using a pre-populated multidimensional data cube includes pre-populating the multidimensional data cube based on values from the relational database system; executing one or more transactions using values in the multidimensional data cube instead of using the values from the relational database system; generating one or more entries that update the relational database system using results generated from executing the one or more transactions; posting the one or more entries to the relational database system; and repopulating the multidimensional data cube based on values from the relational database system that changed as a result of posting the one or more entries to the relational database system.

Abstract: A method includes storing entity records that include entity information that describes an entity and an application link that accesses an application state associated with the entity. The method includes receiving event data from user devices that indicates a number of times each of the application states was accessed by the user devices. The method includes determining a popularity score for each entity record based on the received event data, wherein the popularity score indicates the number of times the application state for the entity record was accessed relative to the number of times other application states were accessed. The method includes identifying a set of preliminary result entity records based on a search request, generating result scores for each of the preliminary result entity records based on the popularity scores, and generating search results that include application links from the preliminary result entity records.

Abstract: A method includes receiving a user ID for a user device and entity identification data that indicates an entity. The method includes identifying first and second action links using the entity identification data. The first and second action links are configured to cause the user device to access first and second application states associated with the entity. The first and second action links are associated with first and second action IDs that indicate functionality of the first and second application states. The method includes determining first and second usage values using the user ID. The first and second usage values indicate a number of times the user device accessed application states associated with the first and second action IDs. The method includes scoring the action links based on the first and second usage values, selecting one of the action links based on the scores, and transmitting the selected action link.

Abstract: Modifying a document being entered by a user by adding data from at least one of a plurality of news items relevant to the document includes determining other documents in a collection of documents that are relevant to the document being entered by the user, constructing a filter based on content of the document being entered by the user and on the other documents, presenting on a display the plurality of news items selected from a plurality of news feeds according to the filter, the user selecting from the display at least one of the news items, and the user inserting data from the at least one of the news items into the document. The document may be a note and the collection of documents may be a notebook. The note and the notebook may be provided by the OneNote product from Microsoft Corporation and/or by the Evernote product.

Abstract: A method of accelerating execution of a transactions includes storing financial ledgers in a relational database, prepopulating a multidimensional data cube using the relational database, executing the transactions using the data cube by querying the data cube for aggregated balances to generate result values, generating accounting journal entries that update each account in the ledgers affected by the transactions using the result values from the data cube, posting the accounting journal entries to the financial ledgers in the relational database, repopulating the data cube with the changes resulting from the posted journal entries, and updating the aggregated balances of the data cube.

Abstract: Providing incremental search suggestions as a user enters terms in a search query includes determining if a recently entered term is in a context-free dictionary of natural language phrases, generating natural language query search completion candidates corresponding to terms provided by the user in the search query if the recently entered term is in the context free dictionary, determining if the recently entered term contains a keyword hint if the recently entered term is not in the context free dictionary, generating keyword search completion candidates if the recently entered term is at least part of a keyword hint, scoring the candidates from a current iteration and any previous iterations from previously entered terms to provide a set of possible candidates, and ordering the possible candidates based on at least the scoring. Providing incremental search suggestions may also include building compound search queries that include natural language phrases and keywords.

Abstract: Providing incremental search suggestions from a content database include accessing the content database to determine possible candidates for the search suggestions, scoring each of the candidates based at least partially on a non-monotonic document frequency function, where candidates that appear a first amount corresponding to a relatively frequent occurrence in the content database and candidates that appear a second amount corresponding to a relatively infrequent occurrence in the content database both score lower than candidates that appear in the content database with a frequency that is between the first amount and the second amount, and ordering the possible candidates based on at least the scoring. Possible candidates may include named entities and n-grams. The n-grams may only be unigrams and bigrams. Stop words may be filtered out of the n-grams. Scoring may include taking into account term frequency.

Abstract: Determining experts based on a search query of a user includes identifying items in a content collection that correspond to the search query, determining authors of the items, and ranking the authors according to relevance to the search query for each of the items for each of the authors. Determining experts based on a search query of a user may also include complementing the query with additional public search results prior to identifying the items. Complementing the query may include using an external data source to search based on the query. The external data source may be selected from the group consisting of Google Search, Yahoo Search, and Microsoft Bing. Determining experts based on a search query of a user may also include presenting the authors to the user in order of ranking The query may be a natural language query.
