20180159803 | HEADER REPLICATION IN ACCELERATED TCP (TRANSPORT CONTROL PROTOCOL) STACK PROCESSING - In one embodiment, a method is provided. The method of this embodiment provides storing a packet header at a set of at least one page of memory allocated to storing packet headers, and storing the packet header and a packet payload at a location not in the set of at least one page of memory allocated to storing packet headers. | 2018-06-07 |
20180159804 | SYSTEMS AND METHODS FOR PROVIDING A COMMENT-CENTERED NEWS READER - Methods and systems for linking comments to portions of content items. An example computing device receives information associated with a content item produced by a source system, the content item being accessible to other the computing devices via a network and receives a comment associated with the content item, the comment produced by one of the other computing devices. In response to receiving the information and the comment, the computing device predicts a subsection of the content item to link to the received comment based at least on details associated with the content item and the comment, then makes information associated with the predicted subsection of the content item available to other computing devices requesting access to the content item. | 2018-06-07 |
20180159805 | Messaging System - A method, apparatus and program product for use in relation to communications between a first user and a second user. There is provided a user agent to act on behalf of the second user by performing operations of: analysing content of a message from the first user destined for the second user, the content being composed by the first user; determining information concerning the second user; automatically predicting content of a response of the second user to the message based on the analysed message content and the determined information on the second user; and automatically outputting data causing the automated response to be provided to the first user. | 2018-06-07 |
20180159806 | INFORMATION PROCESSING METHOD, INFORMATION PROCESSING APPARATUS, AND RECORDING MEDIUM HAVING PROGRAM RECORDED THEREON - In an information processing method, display of a question and acquisition of an answer from a user to the question are repeated to narrow down information the user desires to make a search. A question regarding a target of the search is displayed in a first mode on a display included in a terminal. An answer inputted from the user to the question is acquired through the terminal. When the question is displayed, first information regarding a situation of a narrowing-down progress is displayed above the question in a second mode, and second information regarding a guide for answering the question is displayed below the question in a third mode. | 2018-06-07 |
20180159807 | DUAL SERVER SYSTEM FOR SENDING A LARGE EMAIL ATTACHMENT - An electronic device with a touch-sensitive surface and display can execute a messaging application. The messaging application provides options for sending a message with a large attachment. In one option it allows for sending a message with a large attachment by uploading and storing the attachment on a cloud server, embeds a link to the storage location in the message, and sends the message without the attachment. The messaging application may also include a UI element in the message that includes an indicator about the status of the stored attachment. Furthermore, the messaging application may embed in the message a smaller sized version of the attachment before sending the message. The status indicator may display whether the link to the storage location has expired or whether the attachment has previously been retrieved from the cloud server. | 2018-06-07 |
20180159808 | MESSAGE CLASSIFICATION - One or more computing devices, systems, and/or methods for message classification are provided. For example, a set of messages is clustered into a set of clusters. A cluster comprises messages with similar features (e.g., similar subject lines, message body content, sender information, recipient information, structure, user action such as reading or deleting, spam vote information, etc.). Cluster features are computed for the clusters based upon features of messages within such clusters. A first table, comprising cluster entries corresponding cluster features of clusters, and a second table, comprising message entries corresponding to clusters to which messages are assigned, are created. Message features of a message are created, using the first table and second table, based upon features of the message and cluster features of clusters to which the message is assigned. A message classifier is used to classify the message (e.g., spam, safe, a threat, etc.) based upon the message features. | 2018-06-07 |
20180159809 | METHOD AND DEVICE FOR MESSAGE READING - The present disclosure relates to a method and a device for message reading. The method includes: when there is a notification of unread message displayed on a terminal screen, obtaining a reading operation instruction, where the reading operation instruction includes a position at which a click on the terminal screen is taken place; when the position is located in a first preset area having a fingerprint recognition circuit, receiving fingerprint information on the terminal screen and recognizing fingerprint information received; and when the fingerprint information is determined to be legitimate, opening a reading interface corresponding to the notification of the unread message and displaying the unread message using the reading interface. | 2018-06-07 |
