Abstract: A method is provided for deleting a content element of a chat history lacking long-term relevance. The method includes receiving a content element, assigning the content element to a topic, determining a relationship index value for the content element to the topic using a validity value, which is a function of an access rate and a credibility index value. The method also includes comparing the relationship index threshold value for the topic of a first chat user, where the content element has been generated by a second chat user, and linking the content element of the second chat user to the topic in the chat history of the first user. The content element is deleted if it is not linked to any other chat history of another chat user of the plurality of chat users, thereby saving long-term chat storage space.

Abstract: A method is provided for deleting a content element of a chat history lacking long-term relevance. The method includes receiving a content element, conditionally assigning the content element to the topic, determining a relationship index value for the content element to the topic using a validity value, which is a function of an access rate and a credibility index value. The method may also include comparing the relationship index threshold value for the topic of a first chat user, where the content element has been generated by a second chat user. The method also includes linking the content element of the second chat user to the topic in the chat history of the first user, and deleting the content element if it is not linked to any other chat history of another chat user of the plurality of chat users.

Abstract: A random number generator includes a photon source and one or more photon detectors of the SPAD type (311) configured to detect a photon flow equal to ?, wherein the photons are generated by the photon source. The random number generator furthermore includes an electronic sampler. The electronic sampler is configured in such a way as to detect the arrival time t of a photon incident on each SPAD photon detector (311) for each one of the observation windows Tw, and are also configured in such a way as to convert the arrival time t into a binary sequence. In the generator of the invention the photon source and the electronic sampler are configured in such a way that the product ?*Tw is lower than or equal to 0.01.

Abstract: A messaging system creates a content index for messages for user selection of all of part of a message. By selecting only an indexed portion of the message, the user avoids downloading unneeded portions of the message. The content index is created according to pre-defined user criteria and semantic analysis of the contents of the message.

Abstract: Method and apparatus for rating applications. Execution of an application on a computing device is monitored to determine usage information for a user. Embodiments capture a plurality of images and for each of the plurality of images, extract, from the respective image, a set of user facial features and determine an user emotional state corresponding to the respective set of user facial features by applying a model correlating a set of predefined emotional states with corresponding predefined facial features. A trend of user emotional states across a plurality of executions of the application on the computing device is determined. Embodiments calculate a rating for the application based on the usage information, the user emotional states, and the trend of the user emotional states. The rating is sent to a server over a network connection for use in an aggregate rating of the application.

Abstract: A computer-implemented method includes identifying a document accessible to a revision control system. The method identifies at least two document versions for the document. The method receives a plurality of critical artefacts. The method parses each of the at least two document versions for the plurality of critical artefacts to yield a critical artefact table for each of the at least two document versions. The method compares the critical artefact table for a first document versions with the critical artefact table for a second document versions. The method identifies one or more corresponding critical artefacts from the first version and the second version. The method compares each document version to yield a set of differences between the at least two document versions. The method organizes the set of differences between the at least two document versions based on the one or more corresponding critical artefacts.
