A method for ranking a plurality of documents relevant to a user profile comprises determining a high resolution representation for the user profile, computing a high resolution representation for each document, calculating a rank for each document based on the high resolution representation of the document and the high resolution representation of the user profile, recalculating the rank for each document based on a lower resolution representation of the document and/or a lower resolution representation of the user profile when the rank of each document is not satisfactory, and outputting a number of the plurality of documents sorted by the rank of each document, when the rank is satisfactory. The high resolution representation can be a discrete wavelet transform. The lower resolution representation can be recalculated by averaging the values of the discrete wavelet transform. Outputting the number of documents can comprise displaying the documents on a device.

The present invention discloses an architecture for document archival built on network-centric groupware such as Internet standards-based messaging. Archiving and retrieving and classifying documents into meaningful collections is accomplished in a manner similar to sending email to recipients, retrieving messages from folders, and classifying messages into folder hierarchies. In the simplest scenario, if saveme.com is the archiving server's name, then sending an email to abc&commat;saveme.com will cause the contents of the email message to be archived in the abc mailbox. The archived documents may be automatically stored in jukeboxes of non-tamperable media such as Write Once Read Multiple (WORM) Compact Disks (CD), which provide high storage capacity, low cost compared to magnetic disks, random data access, and long-term stability. The present invention leverages existing messaging infrastructures, and the resulting environment is not intrusive, easier to administer, and easier to deploy than conventional dedicated document archival systems.

System for archiving electronic documents using messaging groupware

A work flow management system (WFMS) can execute one or more instances of a workflow process. The execution of each workflow process is comprised of the execution of component activities. More particularly, dynamically predicting deadlines of a workflow process, whether a workflow process will escalate and whether it is beneficial to preemptively escalate a workflow process.

Methods for dynamically predicting workflow completion times and workflow escalations

A messaging system in which a core messaging infrastructure stores and manages messaging attributes, but applications external to the core infrastructure define and modify most attributes. Attribute types may be easily defined or modified, the manner in which attribute values are obtained may be easily defined or modified, and the entity types to which attributes are assigned may be easily defined or modified. The messaging system includes a plurality of messaging entities, such as messages, folders, and users, a plurality of attributes associated with the messaging entities, and a plurality of applications. Each application is operable to examine and modify at least some of the messaging entities and attributes. An application selection device is operable to examine at least some of the messaging entities and at least some of the attributes and to select an application to be invoked, from among the plurality of applications, based on values of the examined messaging entities and attributes. An application invocation device invokes the selected application. The applications may define and modify a type of an attribute and/or may define and modify an association of an attribute with a messaging entity.

Messaging system with application-defined states

A messaging system, and method of operation thereof, which supports combinations of directory and mailing list addressing mechanisms. Intended message recipients are specified as declarative addresses, which may include combinations of directory and mailing list information. The messaging system includes a messaging server and an address resolution module. The messaging server receives a message from a sender system and transmits the message to the recipient system. The address resolution module, which is coupled to the messaging server, receives a declarative address associated with the message, resolves the declarative address into at least one messaging address and transmits the at least one messaging address to the messaging server. In one embodiment, a database system may be coupled to the address resolution module to allow address resolution based on information stored in a database. The address resolution module generates a database query based on the declarative address and transmits the generated query to a database system. The database system receives a database query, retrieves at least one messaging address specified by the query and transmits the retrieved at least one messaging address to the address resolution module.

Declarative message addressing

The present invention is a messaging system, and method of operation thereof, which provides message recipients with control over the delivery of message and charges the cost of a message to the sender of the message. A message is received at a messaging server from a sender system, the message including an indication of a recipient system. A notification message is transmitted to the recipient system, allowing the message recipient to determine whether they desire the message to be delivered. If so, an activation message is received from the recipient system and the message is transmitted to the recipient system. A charge for the message is assessed to the sender of the message. The message is stored in the messaging server until the activation message is received. At least a portion of the assessed charge may be credited or debited to the recipient of the message. The message may include any type of electronic information, such as text, graphics, video and audio information, and may be encrypted or unencrypted.

Sender-paid electronic messaging

An apparatus and method is provided that supports continuous media for conventional networked workstations and PC's. Described are user-level mechanisms and policies designed to give good, efficient multimedia service under the mild assumption that the operating system provides a preemptive real-time scheduling class that can be used to give CPU cycles to the multimedia processes in preference to other processes that are not time sensitive. There are no modifications to the operating system kernel and isochronous networks are not required. It suffices for an application to state that it wants to play a particular stream of a type known to the server (e.g. a file containing MPEG-1 video 320.times.240 pixels, 8-bit color, 30 frames per second), or for the application to specify a frame rate and an index describing the offset of each frame in a file.

Dynamic hierarchical network resource scheduling for continuous media

A distributed database management computer system includes a plurality of nodes and a plurality of database pages. When a first node in the computer system updates a first database page, the first node generates a log record. The first node determines whether it manages the first database page. If the first node determines that it manages the first database page, the first node writes the log record to a log storage local to the first node. However, if the first node determines that it does not manage the first database page, the first node then determines whether it includes a local log storage. If the first node includes a local log storage, the first node writes the log record to the local log storage, even if the first node does not manage the first database page. If the first node does not include a local log storage, the first node sends the log record to a second node managing the first database page.
