Abstract: Semantic Web attributes are transmitted via an electronic message such as an email message. The attributes are extracted from the message by a program agent according to a predetermined plan. The extracted attributes are saved in storage wherein the storage is optionally an annotation store.

Abstract: An Event Manager receives events requiring action. The events are parsed into event action types which are placed in an Event Queue. Program agents in a pool of agents are dynamically instantiated and retired from the pool based on the number of queued events by type. Program agents, when available, initiate a search for a work entry on the Event Queue that is of a type that the agent can handle. When an agent finds work, the corresponding Event Queue entry is marked as assigned to the agent and the agent performs the action associated with the work entry.

Abstract: A method, apparatus, and computer program product for graphically presenting compatible workflow steps to a user through a graphical user interface are disclosed. The method includes graphically displaying a plurality of steps in a workflow. A user's selection for at least one step in a plurality of steps to denote at least one selected step and at least one non-selected step is received. The method further includes determining if a set of one or more output parameters of the selected step is acceptable as an input of the non-selected step. An appearance of the non-selected step is graphically changed if the output parameters are acceptable. The method also includes determining if a set of one or more output parameters of the non-selected step is acceptable as an input of the selected step. An appearance of the non-selected step is graphically changed if the output parameters are acceptable.

Abstract: Semantically linked pages are queried based on a user supplied interest vector. The interest vector provides a weight for presenting results from the query of pages. The interest vectors are used to calculate the importance of pages of a query based on the weight of semantic links associated with the page known as page rank indicators. Optionally, the calculation is augmented by other page ranking algorithms. An indication of the resulting pages is displayed according to the calculated importance. Preferably the calculation utilizes a dot product of page rank and user interest vectors.

Abstract: A method and system are disclosed for indexing a set of statements, such as RDF statements, that are described in accordance with a specified ontology. The method comprises the steps of defining a set of indexing rules, and using these indexing rules to examine the statements to identify selected ones of the statements and to generate one or more indices from said selected ones of the statements. In a preferred embodiment, the rules match certain predicates of RDF statements to certain indices. Also, preferably, an RDF storage system may be configured with said set of indexing rules. When RDF statements are added to the RDF storage system, each statement is examined by the indexing subsystem. If the predicate of a statement matches one of the predicates of said set of indexing rules, that rule is applied to the statement.

Abstract: Disclosed are a method, user interface, and computer readable medium for graphically representing compatible workflow components to a user. The method includes graphically displaying, in a graphical user interface, a plurality of steps in a workflow. A user's selection is received, wherein the selection is for at least one step in the plurality of steps The user's selection denotes at least one selected step. At least a portion of the graphical user interface is dynamically populated for displaying a list with at least one workflow component that is compatible to accept an output from the selected step. The list can also display at least one workflow component that can provide an output to the selected step. The workflow component is selectable by the user so that it can be added to the workflow.

Abstract: A system, method and program product for interactively scheduling and negotiating meetings wherein an active agent program accepts meeting criteria from a meeting requester and interacts with invitees to resolve availability according to the meeting criteria. The agent transmits the negotiated meeting schedule to invitees and optionally requires confirmation from invitees.
