  • Patent number: 11869484
    Abstract: The present invention provides an apparatus and method for automatic generation and update of a knowledge graph from multi-modal sources. The apparatus comprises a conversation parsing module configured for updating a dynamic information word set VD with labelled words generated from extracted from the multi-modal sources; updating a static information word set VS based on extracted schema of relations extracted from the multi-modal sources; and generating pairs of question and answer based on the dynamic information word set VD, the static information word set VS and the one or more sentence patterns; and a knowledge graph container configured for updating a knowledge graph based on the extracted entities of interest and schema of relations. Therefore, an efficient and cost-effective way for question decomposition, query chain construction and entity association from unstructured data is achieved.

  • Publication number: 20070224278
    Abstract: Triamcinolone compositions, and methods of using such compositions, useful for injection into the vitreous of human eyes or into a joint are provided. Such compositions can include triamcinolone particles present in a therapeutically effective amount, a viscosity inducing component, and an aqueous carrier component. The compositions have viscosities of at least about 10 cps or about 100 cps at a shear rate of 0.1/second. In a preferred embodiment, the viscosity is in the range of from about 80,000 cps to about 300,000 cps. In a most preferred embodiment, the viscosity is in the range of from about 140,000 cps to about 280,000 cps t a shear rate of 0.1/second at 25° C. The compositions advantageously suspend the triamcinolone particles for prolonged periods of time.

  • Publication number: 20070098938
    Abstract: A container method for product integrity and identification includes a bottle formed from a resin comprising polyethylene terephthalate and a first set of dye stuffs present in the bottle in an amount sufficient to absorb visible and ultraviolet wavelengths which may cause product degradation. A second set of dyestuffs is present in the bottle in an amount sufficient to provide an identifying blue color of the bottle while enabling sufficient transmission of the light for visual inspection of the product contained in the bottle.
