  • Patent number: 8108397
    Abstract: A system and method for processing message threads is provided. A plurality of messages, each comprising a message body, is grouped by conversation thread. The message bodies of the messages are compared. Each message recursively contained in at least one other message is identified as a near duplicate message. An attachment sequence is generated for at least part of each attachment associated with one or more of the messages. The attachment sequences associated with the near duplicate messages are compared. Each near duplicate message having an attachment sequence not matching the attachment sequence of any other near duplicate message is identified as a unique message.

  • Patent number: 8095613
    Abstract: A system, method, and computer program product dynamically prioritizes electronic messages. An electronic message having one or more properties is received. These message properties can include, a particular sender or body text. Information describing past activity of a recipient user of the electronic message is accessed. A priority is determined for the electronic message, where the determining is based at least in part on a comparison of a property of the electronic message with the accessed information. The priority determination may include detecting the presence of a request in the electronic message, determining the social weight of the sender of the electronic message, determining the temporal urgency of the electronic message, or determining the relevance of the electronic message, for example. An indication of the priority of the message is presented to the recipient user.

  • Publication number: 20110320453
    Abstract: A system and method for grouping similar documents is provided. Frequencies of occurrences are determined for terms and noun phrases within a set of documents. A subset of the documents is selected by removing those documents having terms and noun phrases that fall outside a bounded range of upper and lower conditions for frequency of occurrence. Each of the documents in the subset is mapped to a cluster of documents based on a similarity of the documents to the cluster documents.

  • Patent number: 8015188
    Abstract: A system and method for thematically grouping documents into clusters is provided. Concepts are extracted from a plurality of documents. The concepts include nouns or noun phrases. A number of occurrences for each concept are determined within each document. A bounded range is applied to the concepts and a subset of the concepts is selected by removing the concepts that fall outside the bounded range. The bounded range includes upper edge conditions and lower edge conditions. Themes are generated from the subset of concepts by identifying two or more concepts with common semantic meaning. Clusters of the documents are generated based on the themes.

  • Patent number: 7989283
    Abstract: A manufacturing method of a semiconductor device is provided for improving the reliability of a semiconductor device including a MISFET with a high dielectric constant gate insulator and a metal gate electrode. A first Hf-containing insulating film containing Hf, La, and O as a principal component is formed as a high dielectric constant gate insulator for an n-channel MISFET. A second Hf-containing insulating film containing Hf, Al, and O as a principal component is formed as a high dielectric constant gate insulator for a p-channel MISFET. Then, a metal film and a silicon film are formed and patterned by dry etching to thereby form first and second gate electrodes. Thereafter, parts of the first and second Hf-containing insulating films not covered with the first and second gate electrodes are removed by wet etching.

  • Patent number: 7836054
    Abstract: A system and method for processing a message store for near duplicate messages is provided. Metadata, content, and each attachment associated with messages are extracted. Near duplicate messages in the message store are identified. Compound digests taken of the metadata for, of the content contained in, and of the each attachment associated with each of the messages in the message store are compared. Each message having a compound digest not matching the compound digest of any other message is marked as unique and each message having a compound digest matching the compound digest of at least one other message is marked as an exact duplicate. Messages remaining unmarked and having similar content are grouped into sets that each includes one or more near duplicate messages. One of the near duplicate messages is designated as unique and each remaining near duplicate message in the set is designated as a near duplicate.
