Abstract: Architecture for detecting and removing obfuscating clutter from the subject and/or body of a message, e.g., e-mail, prior to filtering of the message, to identify junk messages commonly referred to as spam. The technique utilizes the powerful features built into an HTML rendering engine to strip the HTML instructions for all non-substantive aspects of the message. Pre-processing includes pre-rendering of the message into a final format, which final format is that which is displayed by the rendering engine to the user. The final format message is then converted to a text-only format to remove graphics, color, non-text decoration, and spacing that cannot be rendered as ASCII-style or Unicode-style characters. The result is essentially to reduce each message to its common denominator essentials so that the junk mail filter can view each message on an equal basis.

Abstract: The principles of the present invention extend to efficiently and reliably providing message related data. Generally, data fields of electronic messages and attachments are created in accordance with an electronic message schema hierarchy. An electronic message can include links to folder items that represent message folders. An electronic message can also include links to contact items that represent message participants. Message applications can register for folder spaces such that each message application is aware of folders that are primarily controlled by other message applications. A link to a contact item can be selected to access current contact related data for a message participant, even when the contact related data has changed since an electronic message containing the link was received.

Abstract: The present invention extends to methods, systems, computer program products, and data structures for efficiently storing and accessing electronic messages. Generally, electronic messages are created and transformed in accordance with an electronic message schema hierarchy. Electronic messages can be created according to a general message schema that defines a format for data fields that are common to all types of electronic messages (e.g. electronic mail, instant message, fax message). Electronic messages can also be extended according to message extension schemas that define formats for adding protocol specific and/or or application specific data fields to an electronic message. Data fields added in accordance with message extension schemas can differ between electronic messages types.

Abstract: Various embodiments protect against undesirable activities, in at least some embodiments, by combining the protection of a data or message filter with the user's own knowledge and judgment. In at least some embodiments, data or a message that is suspected of being associated with an undesirable activity is identified and indicia is provided to a user that the message is suspect. The data or message is presented to the user in a protected environment that allows the user to access the data or message in full fidelity, but prevents them from interacting with the data or message in a manner which would expose them to the undesirable activity. After reviewing the data or message in the protected environment, the user can decide how the message should thereafter be treated.

Abstract: The present invention provides for a distributed computing system that is capable of determining when data needs to be synced between two computer devices because data has changed on at least a remote device. More particularly, the present invention provides for a sync adapter that uses sync data to detect that a property on a device is new and needs to synchronize with corresponding data on another machine. The sync data is specific to the two devices in that the sync data mirrors data that was last synchronized between these two computing devices. Other example embodiments use the sync data to detect and mark data as low fidelity data for identifying any date and time information associated with the low fidelity data as potentially unreliable.

Abstract: The present provides for consistent resolution of data conflicts when synchronizing data between two or more devices in order to reduce the likelihood of an infinite synchronization loop within a distributed computing system. More particularly, example embodiments provide for a conflict resolution algorithm capable of generating unique values for properties that are in conflict. Data selection criteria can then be used to determine which of the properties should be used to resolve the conflict. Such data selection criterion increases the likelihood of providing consistent resolution of similar data conflicts between other devices in the distributed system.

Abstract: Keyword analysis and arrangement are described. In an implementation, a method includes processing a plurality of items to extract a plurality of keywords contained in the items. One or more of the keywords is output for display as arranged in one or more hierarchies such that at least one of the keywords is selectable to navigate to items that are configured as emails and relate to that keyword.

Abstract: Various embodiments can utilize information that is displayed for a user to automatically generate a list of keywords and use that list as a means to display supplemental information that is relevant to the keywords. In at least some embodiments, the displayed information is analyzed using an extraction algorithm to identify words or, more generally, character strings of interest. If these words or character strings of interest are determined to constitute relevant search terms or “keywords”, then a special user interface portion can be used to display this supplemental information along with the information that is already displayed for the user. This supplemental information can include the search terms themselves, ads that pertain to the search terms, and/or search results that have been ascertained from a web search engine.

Abstract: The present invention involves a system and method that facilitate extracting data from messages for spam filtering. The extracted data can be in the form of features, which can be employed in connection with machine learning systems to build improved filters. Data associated with origination information as well as other information embedded in the body of the message that allows a recipient of the message to contact and/or respond to the sender of the message can be extracted as features. The features, or a subset thereof, can be normalized and/or deobfuscated prior to being employed as features of the machine learning systems. The (deobfuscated) features can be employed to populate a plurality of feature lists that facilitate spam detection and prevention. Exemplary features include an email address, an IP address, a URL, an embedded image pointing to a URL, and/or portions thereof.

Abstract: Generally, the present invention provides for a distributed computing system that is capable of associating time-date information with a property value in the database. The distributed computing system has a device that stores properties in a database without corresponding time-date fields, and thus is considered a low fidelity or legacy device. Example embodiments provide that time-date information corresponding to remote property values can be identified and formatted in a standard format parsable by one or more devices in the distributed computing system. The formatted time-date information is sent to the remote database for storage in a field associated with the remote property values. The formatted time-date information can then subsequently be used in resolving conflicts between property values.

Abstract: The present invention extends to methods, systems, computer program products, and data structures for presenting message attachments independent of electronic messages at a user-interface. A message application submits a query for message related data that satisfies query criteria. A database application receives the query and identifies a message attachment that satisfies the query criteria. The database application returns a message attachment link to the message attachment in response to the query. The message attachment link provides access to the message attachment independent of an electronic message that included the message attachment. The message application receives the message attachment link. The message application presents the message attachment link at a user-interface independent of the electronic message such that the message attachment can be accessed without first accessing the electronic message.

Abstract: The present invention extends to methods, systems, computer program products, and data structures for maintaining multiple versions of electronic bodies in a common database. A computer system maintains an association between an electronic message and a plurality of versions of a corresponding message body in a database that is accessible to a plurality of messaging applications. Versions of the corresponding message body can be stored in different formats that vary in fidelity. A messaging application submits a request to access an electronic message. An operating system receives the request and identifies data formats supported by the messaging application. The operating system provides the messaging application with an appropriate version of the message body from the database based on the supported data formats. The messaging application receives the version of the message body and utilizes the version of the message body to perform a message related operation.

Abstract: Mechanisms for organizing messages across different message types. This may be accomplished by using a single integrated user interface in which messages across a variety of different message types are represented in a common way. For example, the user experience of placing a telephone call is standardized, regardless of the actual telephone technology (Cell Phone, VoIP, or POTS) used to conduct the telephone conversation. Also, addition to a general log that includes the overall list of messages, each message also has a separate, message-based log, thereby allowing for more flexible querying and organization of the messages regardless of the message type.

Abstract: A mechanism for placing a telephone call while at the same time communicating context (e.g., subject, importance and/or nature) of the telephone call. The caller uses a mechanism on a user interface to instruct a caller computing system to place a telephone call to a callee computing system. Using the same user interface, the caller also identifies some contextual information for the telephone call such as, for example, the subject, importance and/or nature of the telephone call. The caller computing system then constructs a call invitation data structure that includes both an invitation to the callee to engage in a telephone conversation and the user-entered identification of the context of the telephone call. Upon receiving the call invitation data structure, the callee computing system reads the identification of the context of the telephone call, and then takes appropriate action based on the context for the telephone call.
