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 method and system for a processing device 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 derive a first size value of the number of elements of the identified signature based on a set of size values of signatures that includes a maximum size value representing the largest number of elements in a signature. The processing device may derive a set of second size values of the number of elements of a second signature that is similar to the identified signature based on the set of size values of signatures. The processing device may generate a plurality of partial signatures from one or more combinations of elements of the identified signature. For each partial signature of the plurality of partial signatures, the processing device may combine the elements of the partial signature into one or more tokens.

Abstract: A method for a processing device to group data items of a list of data items is disclosed. The processing device may identify a signature of a data item, the signature including a set of elements. The processing device may select a subset of the elements of the identified signature to form one or more partial signatures. The processing device may combine the selected subset of elements to form one or more tokens. The processing device may determine whether the one or more tokens is marked with one or more markers in a memory, the memory configured to contain an existing set of markers for tokens. The processing device may assign the data item to at least one group when one or more tokens is marked with the one or more markers in the memory.

Abstract: A method for determining influential broadcast messages in which a processing device identifies a plurality of re-posts of a post, wherein each re-post comprises a time stamp, determines whether the time stamp of the re-post is within a first time interval or a second time interval, increments a first count associated with the first time interval when the time stamp is within the first time interval or a second count associated with the second time interval when the time stamp is within the second time interval, and determines a public sentiment attribute associated with the post in view of a comparison between the first count and the second count.

Abstract: A method for facilitating Web content aggregation initiated by a client is disclosed. A Web site aggregation list is created. At least one Web site in the aggregation list is spidered from a user-identified computer. At least one attribute of content of the at least one spidered Web site is merged with at least one attribute of content of another Web site. The merged attributes are displayed to a user.
