  • Patent number: 11347813
    Abstract: A system and computer implemented method for cataloging database metadata using a signature matching process are provided. The method includes receiving an input name to be matched to a key in a seed table; generating a first fingerprint by decomposing the received input name into a first set n-grams; generating, based on the received input name, a second fingerprint using a predetermined pronunciation schema, wherein the second fingerprint is a phonetic fingerprint; generating a third fingerprint by decomposing the second fingerprint into a second set of n-grams; identifying a matching key by matching any combination of the first fingerprint, the second fingerprint, and the third fingerprint against keys in the seed table; and cataloging the metadata with the matching key as a tag.

  • Patent number: 11226970
    Abstract: A method and system for tagging database columns are presented. The method includes receiving an input column name of at least one column in a database; performing signature matching of the input column name to contents of a seed table; determining a first confidence score for the signature matching; and tagging a matching value in the seed table as a tag for the input column name, when a first confidence score exceeds a first threshold value.

  • Patent number: 11106642
    Abstract: A system and computer implemented method for cataloging database metadata using a probabilistic signature matching process are provided. The method includes receiving an input name to be matched to keys in a data corpus; dividing the received input name into a plurality of text segments; identifying a set of matching keys by matching each of the plurality text segments against keys in the data corpus; analyzing the set of matching keys to construct a tag; and cataloging the metadata with the matching key as the construct tag.

  • Patent number: 11066558
    Abstract: The present invention relates to an asphalt composition enabling one to provide an asphalt pavement in which the occurrence of rutting and fatigue cracking is inhibited and a method for producing the same, and to an additive for asphalt. The asphalt composition contains asphalt and cellulose, wherein the content of the cellulose is 0.01 part by mass or more and 10 parts by mass or less based on 100 parts by mass of the asphalt, and a crystallization index of the cellulose is 50% or less.

  • Patent number: 9724702
    Abstract: A particle diameter of a raw material to be pulverized can be decreased within a short time period. A vibration mill includes a container having therein a columnar space with a central axis of the columnar space being almost horizontal while the container is held so as to be vibratable in a direction of within a plane that is almost perpendicular to the central axis, a cylindrical medium disposed in the container so as to be vibratable, and a plurality of pulverizing media disposed inside the cylindrical medium so as to be vibratable. The ratio of an inner diameter of the cylindrical medium in contact with the pulverizing medium to an outer diameter of the pulverizing medium is 2.1 or more. The integrated value of volumes of the pulverizing media relative to a space volume inside the cylindrical medium in contact with the pulverizing medium is more than 25%.

  • Patent number: 9339784
    Abstract: Provided are methods and apparatus for forming electrode active materials for electrochemical cells. These materials include a metal (e.g., iron, cobalt), lithium, and fluorine and are produced using plasma synthesis or, more specifically, non-equilibrium plasma synthesis. A metal containing material, organometallic lithium containing material, and fluorine-containing material are provided into a flow reactor, mixed, and exposed to the electrical energy generating plasma. The plasma generation enhances reaction between the provided materials and forms nanoparticles of the electrode active materials. The nanoparticles may have a mean size of 1-30 nanometers and may have a core-shell structure. The core may be formed by metal, while the shell may include lithium fluoride. A carbon shell may be disposed over the lithium fluoride shell. The nanoparticles are collected and may be used to form an electrochemical cell.
