  • Patent number: 9818066
    Abstract: Technologies are disclosed herein for generating and utilizing machine-learning generated classifiers configured to identify document relationships. Manually-generated data is captured that indicates if documents in a document corpus have a relationship with one another, such as duplicates or variations. A determination may then be made as to whether a classifier is to be generated based on the duplicate decision data. If a classifier is to be generated, machine learning may be performed using training documents from the document corpus and the duplicate decision data to generate a classifier. The machine-learning generated classifier may then be utilized in a production environment to determine whether a new document is a duplicate of documents in the document corpus and/or to identify other relationships between documents in the document corpus, such as documents that are similar or are variations of one another.

  • Patent number: 8527475
    Abstract: Embodiments of a system and method for identifying structured data items lacking requisite information for rule-based duplicate detection are described. Embodiments may include generating a deficiency score for each of multiple structured data items including applying a set of rules based on duplicate detection techniques to each given structured data item in order to perform a comparison of the given structured data item to itself. The deficiency score of the given structured data item may be based on a result of the comparison. Embodiments may also include, based on the deficiency scores of the structured data items, identifying one or more deficient structured data items having less than a requisite quantity of information for performing duplicate detection on structured data items. Embodiments may also include identifying one or more key attributes missing from some of the one or more deficient structured data items and requesting those key attributes.

  • Publication number: 20050163832
    Abstract: The preparation and use of a transducing polypeptide (TP)— lipid vesicle complex having a small proportion of positively charged (cationic) lipids in the make-up of the lipid vesicle, e.g., liposome, for safe and efficient intracellular delivery of therapeutic agents, such as proteins, DNA, small molecules and/or other drugs, into a cell of a higher organism, in vitro or in vivo is disclosed. The delivery system of the invention results in increased efficacy of intracellular delivery of such agents, bypassing the endocytotic pathway of intracellular delivery while at the same time minimizing the toxicity of the delivery system towards the recipient cells.
