A system and method for identifying multimedia content elements are presented. The method includes generating a signature for an unknown multimedia content element (MMCE), wherein the unknown MMCE is a portion of a multimedia content item; comparing a signature of the unknown MMCE to a signature cluster of at least one concept to determine whether each of the at least one concepts is proximate to the unknown MMCE; for each proximate concept, determining a probability that the at least one proximate concept identifies the unknown MMCE; and identifying the MMCE based on the determined probabilities of the at least one proximate concept.

There is provided a method for searching a plurality of information sources using a multimedia element, the method may include receiving at least one multimedia element; generating, by a signature generator, for the at least one multimedia element at least one signature that is unidirectional, and yields compression; generating at least one textual search query using the at least one signature; wherein the generating of the textual search query comprises: (a) searching for at least one matching stored signature that matches one or more of the at least one signature; and (b) using a mapping between stored signatures and textual search queries, selecting at least one textual search query mapped to at least one matching stored signature; searching the plurality of information sources using the at least one textual search query; and causing a display of search results retrieved from the plurality of information sources.

A system and method customizing a display of a user device based on multimedia content elements. The method may include detecting a trigger event; identifying a user profile of the user device, wherein the user profile includes one or more signatures indicating a user interest; accessing signatures for a plurality of multimedia content elements; comparing the signatures of at least one of the plurality of multimedia content elements with the one or more signature of the user profile; and customizing the display of the user device, wherein the customized display includes the at least one interesting multimedia content element.

Input/output (I/O) operation requests from pageable storage mode guests are interpreted without host intervention. In a pageable mode virtual environment, requests issued by pageable storage mode guests are processed by one or more processors of the environment absent intervention from one or more hosts of the environment. Processing of the requests includes manipulating, by at least one processor on behalf of the guests, buffer state information stored in host storage. The manipulating is performed via instructions initiated by the guests and processed by one or more of the processors.

A method for customizing an image. The method includes causing generation of at least one signature for an input image, wherein each signature represents a concept, wherein each concept is a collection of signatures and metadata representing the concept; comparing the generated at least one signature to at least one signature representing at least one common visual attribute among a plurality of reference images; determining, based on the comparison, whether to customize the input image; and customizing the input image with respect to at least one of the at least one common visual attribute, when it is determined to customize the input image.

A system and method for enriching a concept database with homogenous concepts. The method includes determining, based on signatures of a first multimedia content element (MMCE) and signatures of a plurality of existing concepts in the concept database, at least one first concept; generating a reduced representation of the first MMCE, wherein the reduced representation excludes the signatures of the first MMCE that match the at least one first concept; comparing the reduced representation to signatures representing a plurality of second MMCEs to select a first plurality of top matching second MMCEs; generating, based on the reduced representation and the first plurality of top matching second MMCEs, at least one second concept; determining, for each second concept, whether the second concept is a homogenous concept, wherein each homogenous concept uniquely represents the same content; and adding each homogenous concept to the concept database.

A method and system for identifying social trends are provided. The method includes collecting multimedia content from a plurality of data sources; gathering environmental variables related to the collected multimedia content; extracting visual elements from the collected multimedia content; generating at least one signature for each extracted visual element; generating at least one cluster of visual elements by clustering at least similar signatures generated for the extracted visual elements; correlating environmental variables related to visual elements in the at least one cluster; determining at least one social trend by associating the correlated environmental variables with the at least one cluster.

A method and system for identifying a correct orientation of a multimedia content item are presented. The method includes receiving from a user device the multimedia content item; identifying at least one object shown in the multimedia content item; generating by a signature generator system (SGS) at least one signature for the at least one object shown in the multimedia content item; querying, using the at least one generated signature, a deep-content-classification (DCC) system to find at least one concept that matches the at least one object, wherein the querying of the DCC system is performed using the at least one signature generated for each object shown in the multimedia content item; determining a correct orientation of the at least one matching concept; and comparing an orientation of the at least one object to the determined correct orientation to determine if the at least one object is correctly oriented.

A system and method for determining parameters based on multimedia content. The method includes generating at least one signature for at least one multimedia content element, wherein each signature represents a concept, wherein each concept is a collection of signatures and metadata describing the concept; analyzing the generated at least one signature, wherein the analysis includes matching the generated at least one signature to a plurality of other signatures; and determining, based on the analysis, at least one parameter for each multimedia content element.
