    1. Method and system for generating lexicon of cooccurrence relations in natural language

      A method and an apparatus for generating/maintaining automatically or interactively a lexicon for storing information of cooccurrence relations utilized for determining whether or not a sequence of words in a given sentence described in a natural language is semantically correct with the aid of a memory, a data processor and a textual sentence file. A hypothesized cooccurrence relation table for storing hypothesized cooccurrence relations each having a high probabliity of being a valid cooccurrence relation is prepared by consulting the file. A hypothesis for the cooccurrence relation is previously established on the basis of a cooccurrence relation pattern indicating ...

    2. Inference system

      According to this invention, an attribute of an object and a relation of the object with another object is expressed by a paired set of an attribute name and its attribute value. A knowledge base of the frame type is used. In the knowledge base, the attribute of objects and the relation among different objects are expressed in terms of the attribute name/attribute value set, and framed and stored for each objects. The knowledge base is weighted depending on the strength of the attribute of the object and the strength of the relation between different objects. An inference processing ...

    3. Method and system for information storing and retrieval using word stems and derivative pattern codes representing familes of affixes

      An information storage/retrieval system stores information to be retrieved in a storage device having a first memory and a second memory. The first memory stores therein main records each containing an index word data, a derivative pattern code and information pieces while the second memory stores therein auxiliary records each containing a derivative pattern code and supplemental word data. Each derivative pattern code represents a group of words whose primary parts such as word stem parts are commonly combinable with the same remaining parts such as affix parts. Thus, each index word data is qualified by the accompanying derivative ...

    5. Alternative-value paper refund form

      A single sheet paper form contains upon a first side the complete face of a negotiable instrument, nominally a check. Upon the opposite second side are printed one or more coupons in an image area which is partially overlapping of the oppositely juxtaposed image area of the check upon the first side. Severence of the check from the entire form is required in order to negotiate it, simultaneously dividing the coupon(s) and rendering it (them) unredeemable. Alternatively, severance of the one or more coupons from the entire form is required in order to redeem such coupon(s), simultaneously dividing ...

    6. Method and apparatus for analyzing the syntactic structure of a sentence

      An automatic syntax analyzing method is applied to a natural language processing system. It includes the step of detecting by dictionary consultation the syntactic category of words forming an inputted sentence and steps of assumptively applying, when the input sentence includes at least a word unregistered in the dictionary section, an adequate category which satisfies a predetermined grammatical regulation of the input sentence to the unregistered word independent of the dictionary consultation.

    7. String comparator device system circuit and method

      The string comparator device for comparison of strings of indicia at high speeds for use in a system circuit in a computer system. The string comparison device provides a numeric measurement of the degree of similarity between the compared indicia strings as defined by a mathematical algorithm. The algorithm is solved through a new string comparator device or a new program in a computer system. The system circuit in chip form can be connected in a storage loop of a computer system to locate and quickly extract records that are very similar to the supplied query. Inexact queries will rapidly ...

    8. Polyalkoxy monovinylaromatic compound in copolymerization of a conjugated diene with a monovinyl-substituted aromatic compound

      Polyalkoxy monovinyl substituted aromatic compounds, such as 3,4-dimethoxystyrene, function as both comonomer and randomizing agent in organolithium initiated copolymerization of a conjugated diene with a monovinyl aromatic compound, such as of butadiene with styrene. The resultant polymeric product exhibits lower levels of block styrene than does a corresponding copolymer made in the absence of the dimethoxystyrene.

    9. Process for preparing polycarbonates

      Extruded films having reduced proneness to stress-cracking, good resistance to casting resins of unsaturated polyesters and no blocking effect and produced from branched aromatic polycarbonates which are the reaction products of aromatic dihydroxy compounds and branching agents having more than three phenolic hydroxyl groups, with polycarbonate precursors. The films are useful as insulating films in the electrical industry.

    11. Modifiers for high nitrile polymers

      Disclosed herein are high nitrile polymers which have been compounded with a modifier which is a combination of (1) a C.sub.12 to C.sub.28 saturated aliphatic fatty acid ester of glycerol or sorbitan and (2) a polyoxyethylene sorbitan ester. The amount of modifier used is in the range of from 0.01 to 1.0 percent by weight based on the weight of the nitrile polymer. The compounded polymers exhibit lower melt viscosity and increased melt flow. The modifiers also provide improved clarity, gloss and, in certain instances, articles molded from the compounded nitrile polymer exhibit lower ...

    12. Rubber composition for flexible belts

      A highly reversion resistant polyisoprene elastomer composition vulcanized with a low sulfur content is described and used in paper feed belts. The polyisoprene rubber compositions are particularly useful in the paper feed belts used to feed and transport paper in xerographic machines and paper sorting machines. The low-sulfur vulcanizate of isoprene provides high resistance to physical degradation due to dynamic mechanical stress under operating conditions.
