Abstract: A system for monitoring broadcast channels, includes a device for receiving a plurality of broadcast channels, a central search engine operable to search the received channels for a match with a pre-stored profile, a central memory connected to the search engine for storing the profile, and a plurality of user terminals connected to the search engine over a network. The search engine is responsive to commands from the user terminals to store the profiles to be searched in the memory in association with the identity of the user terminal from which the command was received. A device sends an alert signal over the network when a match is found with a pre-stored profile to the user terminal associated with the pre-stored profile. The alert signal identifies the broadcast channel matching the pre-stored profile.

Abstract: A method of organizing electronic documents for storage and subsequent retrieval, involves storing a summary structure describing the structure of summary records associated with each document. Each structured summary record has at least one descriptor field representative of a characteristic of the document. Predefined field entries identify a characteristic of the document. Predefined keyword criteria associated with the field entries are stored. Each document is analyzed to build a text index listing the occurrence of unique significant words in the document. The text index is compared with the keyword criteria to determine the appropriate field entry for the document. For example, one descriptor field might related to topic, which could have the field entries of "financial" or "sports". The preponderance of certain keyword criteria, such as "money" or "shares" would identify the document with the financial topic.

Abstract: A method of organizing electronic documents for storage and subsequent retrieval, involves storing a summary structure describing the structure of summary recordsassociated with each document. Each structured summary record has at least one field representative of a characteristic of the document. A predetermined number of field values identify the value of the characteristic associated the field. Predetermined keyword criteria associated with the field values are stored. Each document is analyzed to build a text index listing the occurrence of unique significant words in the document. The text index is compared with the keyword criteria to determine the appropriate field value for the document. For example, one characteristic field might related to topic, which could have the field values of "financial" or "sports".
