704results about How to "Efficient retrieval" patented technology

This invention relates to a system and methods for determining the placement of an object in a distributed key-value store by mapping the object to nodes in multidimensional hyperspace. A search function supports efficient object retrieval, even when the search query requests multiple objects and specifies them through non-primary keys. In response to a search query, the search is translated into hyperregions in the hyperspace to determine the set of nodes that hold the queried data object. The number of contacted nodes and the number of scanned objects are significantly reduced in comparison to prior art techniques.

The invention is a method, system and computer program for automatically discovering concepts from a corpus of documents and automatically generating a labeled concept hierarchy. The method involves extraction of signatures from the corpus of documents. The similarity between signatures is computed using a statistical measure. The frequency distribution of signatures is refined to alleviate any inaccuracy in the similarity measure. The signatures are also disambiguated to address the polysemy problem. The similarity measure is recomputed based on the refined frequency distribution and disambiguated signatures. The recomputed similarity measure reflects actual similarity between signatures. The recomputed similarity measure is then used for clustering related signatures. The signatures are clustered to generate concepts and concepts are arranged in a concept hierarchy. The concept hierarchy automatically generates query for a particular concept and retrieves relevant documents associated with the concept.

A routing mechanism, service or system operable in a distributed networking environment. One preferred environment is a content delivery network (CDN) wherein the present invention provides improved connectivity back to an origin server, especially for HTTP traffic. In a CDN, edge servers are typically organized into regions, with each region comprising a set of content servers that preferably operate in a peer-to-peer manner and share data across a common backbone such as a local area network (LAN). The inventive routing technique enables an edge server operating within a given CDN region to retrieve content (cacheable, non-cacheable and the like) from an origin server more efficiently by selectively routing through the CDN's own nodes, thereby avoiding network congestion and hot spots. The invention enables an edge server to fetch content from an origin server through an intermediate CDN server or, more generally, enables an edge server within a given first region to fetch content from the origin server through an intermediate CDN region. As used herein, this routing through an intermediate server, node or region is sometimes referred to as “tunneling.”

A user may utilize a communication device, e.g., a wireless phone, mobile device or personal digital assistant (PDA), to contact an information / call center where an operator provides personalized information and communications services to the user in accordance with the invention. Such services include, e.g., providing listing information, contacts information, appointments information, etc. To provide effective connectivity, for example, when a user locates a phone number in his / her private directory using a web browser, the user may utilize a direct connect feature of the invention to initiate a phone call to the desired number over the Internet. In addition, the invention allows for delivery of the appointments information to the user not only via voice connection, but also SMS, email, facsimile, PDA, etc. It also allows for rendering a calendaring service in combination with such services as a TeleConcierge® service which helps the user to plan a future event, e.g., making a restaurant reservation. An appointment record concerning the future event is automatically incorporated into the user's calendar once it is successfully planned. To personalize the services, at least one profile associated with the user is used which specifies the subscribed services and the preferred ways of receiving them. For example, the profile may specify use of a special skilled operator, methods of delivery of information to the user, etc.

An approach is provided for supporting retrieval of web content over a meshed communication network. A first server receives a request from a browser application for the content resident in the web server. The first server includes a downstream proxy configured to modify the request to include information specifying support of a parse and pre-fetch service within an optional header field of the request as to permit handling of the modified request by the web server in absence of an upstream proxy that is communicating with the web server. A second server is configured as the upstream proxy to intercept the modified request and pre-fetch the content from the web server. The second server forwards the pre-fetched content over the communication network to the first server. This approach as particular applicability in relatively high latency networks, such as a satellite communications system.

An automated name searching system incorporates an automatic name classifier and a multi-path architecture in which different algorithms are applied based on cultural identity of the query name. The name classifier operates with a preemptive list, analysis of morphological elements, length, and linguistic rules. A name regularizer produces a character based computational representation of the name. A pronunciation equivalent representation such as an IPA language representation, and language specific rules to generate name searching keys, are used in a first pass to eliminate database entries which are obviously not matches for the query name. The methods can also be implemented as a callable set of library routines including an intelligent preprocessor and a name evaluator that produces a score comparing a query name and database name, based on a variety of user-adjustable parameters. The user-controlled parameters permit tuning of the search methodologies for specific custom applications.

One or more techniques and / or systems are disclosed for efficiently organizing images in a display. A size of an image is scaled by an image scale factor, while an aspect ratio for the image is maintained, where the image scale factor comprises a combination of a first scale distance and a second scale distance.

The image is expanded to mitigate white space in the display after the scaling, while maintaining the image's aspect ratio. This can be performed for a collection of images presented on a display to provide an enhanced user experience.

A dialog with a conversational virtual assistant includes a sequence of user queries and systems responses. Queries are received and interpreted by a natural language understanding system. Dialog context information gathered from user queries and system responses is stored in a layered context data structure. Incomplete queries, which do not have sufficient information to result in an actionable interpretation, become actionable with use of context data. The system recognizes the need to access context data, and retrieves from context layers information required to transform the query into an executable one. The system may then act on the query and provide an appropriate response to the user. Context data buffers forget information, perhaps selectively, with the passage of time, and after a sufficient number and type of intervening queries.

The server system stores the data of images photographed in a plurality of photographing positions in the storage device and retrieves the image data associated with the designated RFID from the storage device.

An automated blocking technique is used as a first step to find approximate matches in a database. The technique builds a blocking set to be as liberal as possible in retrieving records that match on individual fields or sets of fields while avoiding selection criteria that are predicted to return more than the maximum number of records defining a particular special requirement. The ability to do blocking without extensive manual setup at low cost is highly advantageous especially when using a machine learning based second-stage matching algorithm.
