Abstract: Disclose are methods for evaluating a user's interests and making gift recommendations using social media data. Interests and attributes of a user may be detected from social media content and products corresponding to the interests and attributes may be selected and presented as gift recommendations for the user. Methods are disclosed for resolving ambiguity as to interests reflected by textual data in social media content. Also disclosed are methods for inferring a user's interests from the interests of friends of the user.

Abstract: Exemplary embodiments allow performance of stream computations on real-time data streams using one or more map operations and/or one or more update operations. A map operation is a stream computation in which stream events in one or more real-time data streams are processed in a real-time manner to generate zero, one or more new stream events. An update operation is a stream computation in which stream events in one or more real-time data streams are processed in a real-time manner to create or update one or more static “slate” data structures that are stored in a durable manner.

Abstract: Scoring a document is disclosed. One or more metrics is determined in a forward direction. One or more backwards metrics is determined. The document is scored based at least in part on a combination of the metrics.

Abstract: Determining the relevance of a page to a topic in a hierarchy is disclosed. A plurality of paths that include arrivals at the page is determined. A proportion of the paths that include relevant arrivals at the page is determined. And, the relevance of the page is determined based at least in part on the proportion.

Abstract: Determining the relevance of a destination page to a topic is disclosed. A plurality of paths that include arrivals at a destination page are determined. A plurality of paths that include arrivals at the destination page are determined. A proportion of the paths that include arrivals at the destination page that also include a preceding arrival at a distinguished page are determined. The relevance of the destination page based at least in part on the proportion is determined.

Abstract: Determining a mapping between a textual representation in a document and a concept is disclosed. A document is received. A set of candidate textual representations in the document is identified. For at least one candidate textual representation included in the set, an associated concept included in a taxonomy of concepts is determined. The candidate textual representation and the associated concept are provided as output.

Abstract: Disclosed are systems and methods for processing events in an event stream using a map-update application. The events may be embodied as a key-attribute pair. An event is processed by one or more instances implementing either a map or an update function. A map function receives an input event from the event stream and publishes one or more events to the event stream. An update function receives an event and updates a corresponding slate and publishes zero or more events. Systems and methods are also disclosed herein for implementing a map-update application in a multithreaded architecture and for handling overloading of a particular thread or node. Systems and methods for providing access to slates updated according to update operations are also disclosed.

Abstract: Categorizing documents is disclosed. A hierarchy of topics is received. A seed for each topic is determined. One or more documents is received. The seed is used to evaluate the relevance of each document to one or more of the received topics. One or more topics is associated with each document.

Abstract: Techniques for including a hyperlink in a document is disclosed. A document is received via a communications interface. An entity pair is determined by a processor.

Abstract: A method and system for querying hierarchically classified data. The system first receives a query request and then identifies classifications of the data that may satisfy the received query request. The system then displays the identified classifications. In response to selection of a displayed classification, the system displays sub-classifications when the selected classification has sub-classifications and displays the data within the classification when the selected classification has no sub-classifications. In another aspect, the system generates search results for items that are hierarchically classified. For classifications within the hierarchy of classifications, the system generates a search entry containing terms describing the items within that classification. The system then receives a search criteria. The system selects as initial search results those search entries whose terms most closely match the received search criteria.

Abstract: Storage media, systems and methods are disclosed herein for analyzing data streams in real time. More particularly, storage media, systems and methods are presented for processing data streams to calculate results for prospective queries. The results may be advantageously computed prior to the formulation of the specific query, for example, based on a pre-established framework of potential query parameters. More particularly, a universe of potential queries may be extrapolated from the pre-established framework of potential query parameters. Results for each of the potential queries may them be tracked in real time. For example, results for each of the potential queries may be continuously updated based on real-time processing of events in a data stream.
