Abstract: A software application or resource is enabled to participate in a messaging service session conducted over a network and to respond to plain language queries much like a live participant. The software resource registers with a messaging service server when the software resource is initially executed, making it available if included in a user's list of contacts, to be added as a participant. During a messaging service session, a user can direct a message or query to the software resource that is participating. The software resource parses the query, and if the query is understood and data are available, transmits a response that appears within the instant message dialogue window of the users participating in the messaging service session.

Abstract: Natural language (NL) text entered by a user in a document is recognized as corresponding to a tag, causing an action or action associated with the tag to be implemented in the document. Linguistic information, tags, and related actions are managed in a centralized catalog from which they can be accessed. An NL Parser called by a tag recognizer analyzes and normalizes the text using semantic information and returns a parse tree to the tag recognizer. The tag recognizer then compares the parse tree to a corresponding parse tree provided in a dictionary. If a match is found, an instance or tag related to the parse tree in the dictionary is returned to an application in which the document is open to carry out the action associated with the tag. If an ambiguity causes multiple matches to be returned, the user can select one of the instances and related action.
