Abstract: A method for a processing device to determine whether to assign a data item to at least one cluster of data items is disclosed. The processing device may identify a signature of the data item, the signature including a set of elements. The processing device may select a subset of the set of elements to form at least one partial signature. The processing device may combine the selected subset of elements into at least one token. The processing device may determine whether the at least one token is present in a memory. The memory may be configured to contain an existing set of tokens. The processing device may determine whether to assign the data item to at least one cluster based on whether the at least one token is present in the memory.

Abstract: A computing device determines impactful content in transmittable content. The computing device assigns the impactful content in the transmittable content to one or more impactful block units. Each impactful block unit comprises a determined numbers of characters. The computing device extracts the one or more impactful block units from the transmittable content. The computing device places the one or more impactful block units at the end of the transmittable content. The computing device transmits the transmittable content to a plurality of intended recipients. Each character, or a small packet set of sequential characters, of the determined number of characters of the one or more impactful block units is transmitted using a time delay for a particular intended recipient and a pacing method. The one or more impactful block units are to be received substantially simultaneously by the plurality of intended recipients.

Abstract: A method for facilitating substantially simultaneous receipt of content included in at least one document by a plurality of intended recipients is disclosed. At least one portion of impactful content is delimited in the at least one document to define at least one impactful block (IBlock). A remaining portion of content is delimited to define at least one non-impactful block (NIBlock). The least one IBlock is transmitted to be received substantially simultaneously by the plurality of intended recipients.

Abstract: A computing device determines impactful content in transmittable content. The computing device assigns the impactful content to one or more impactful block units. Each impactful block unit comprises a determined numbers of characters and an impactful block of characters comprises one or more impactful block units. The computing device inserts an identifier associated with the impactful content into the transmittable content proximal to the impactful block of characters. The identifier causes a message concerning a financial-related action to be communicated to a plurality of intended recipients when one or more conditions are met. The computing device transmits the one or more impactful block units and the identifier to the plurality of intended recipients using a time delay for a particular intended recipient and a pacing method such that the impactful block units are received substantially simultaneously by the plurality of intended recipients.

Abstract: A method for selecting a subset of content sources from a collection of content sources is disclosed. A server retrieves, in response to a plurality of queries on a topic from a client, using a programmed computer, a plurality of sets of documents from the collection of content sources. The server enumerates all subsets of the plurality of sets of documents. The server calculates, for each subset, a count of effectiveness of a subset and a price of the subset. The server selects a subset having the highest calculated ratio of count of effectiveness of the subset to price of the subset. The server delivers the selected subset of the plurality of sets of documents to the client.

Abstract: A method of facilitating substantially simultaneous receipt of electronic content by a plurality of intended recipients is disclosed. The electronic content is encrypted. The encrypted electronic content is transmitted to the plurality of intended recipients. An acknowledgement packet is received from each of the plurality of intended recipients within a predetermined timeout period. A handicap time is calculated for transmitting a decryption key to each of the intended recipient based on a time associated with the acknowledgement packet last received. Decryption keys are transmitted to the plurality of intended recipients using a delay based on the handicap time, where a decryption key having a smaller handicap time is transmitted prior to a decryption key having a larger handicap time.
