A crawler includes a crawler main body (a rubber crawler main body ()), a tensile body (), guide protrusions (), and flat surfaces (). The tensile body () is provided with a flat portion () that is arranged along a width direction of the crawler main body and a slanting portion () that is slanted and arranged at a width direction outer side of the crawler main body relative to the flat portion (). The guide protrusions () are formed at an inner peripheral face of the crawler main body at a width direction middle portion of the crawler main body. The flat surfaces () are formed at the width direction outer sides of the crawler main body relative to the guide protrusions (). Turning wheels (a driving wheel (), an idling wheel () and rolling wheels ()) provided at a vehicle roll on the flat surfaces (). In a linear region of the crawler main body as seen in a side view of the crawler main body, if a thickness from an imaginary plane projected from the flat portion () in the width direction of the crawler main body to an end edge at a crawler main body width direction outer side of the slanting portion () is represented by L, then a result of subtracting a turning direction length of the crawler main body at the flat portion () from a turning direction length of the crawler main body at the slanting portion () is less than 2&#x3c0;L.

Crawler

A crawler includes crawler body formed by an elastic body shaped into an endless loop, a tensile body embedded in the crawler body and wound around a circumferential direction of the crawler body, guide projections formed at an inner circumferential surface of a width direction central portion of the crawler body and spaced apart in the circumferential direction of the crawler body, a flat face, upon which a rotating wheel provided at a vehicle rolls, forming an inner circumferential surface further toward a width direction outer side of the crawler body than the guide projections and an inclined face, upon which the rotating wheel rolls, inclined from an outer side end portion of the flat face in a crawler body width direction such that a thickness of the crawler body gradually increases toward the width direction outer side and circumferential inner side of the crawler body.

Provided is an elastic crawler and an elastic crawler device capable of achieving both low fuel consumption and excellent ride comfort. The elastic crawler comprises: a main body; cores respectively having a pair of wings and being embedded in a circumferential direction; a track roller rolling surface formed on an inner circumferential surface of the main body; a recess formed on the inner circumferential surface in a manner extending from the track roller rolling surface toward a widthwise outer side; lugs formed on an outer circumferential surface of the main body, the lugs respectively extending in a width direction between the cores from one end overlapping the track roller rolling surface in a thickness direction toward the other end overlapping a part in which the wings of the cores are embedded in the thickness direction. The elastic crawler device comprises the elastic crawler, a sprocket and a track roller.

To provide an implication determining device, an implication determining method, and an implication determining program capable of improving implication determination performance. A new fact determination unit determines whether a given hypothesis is a new fact that indicates a first revealed fact in a hypothesis implied sentence that is a sentence implying the given hypothesis based on a specific expression written in the hypothesis implied sentence. An implication determination unit determines whether the given hypothesis is implied in a sentence to be determined that is a sentence to be determined whether the hypothesis is included.

A data classifier system of the present invention selects a plurality of classifications correlated to data groups so as to output classification axes based on hierarchical classifications and data groups. The data classifier system includes a basic category accumulation means, a classification axis candidate creation means and a priority calculation means. The basic category accumulation means accumulates classifications serving as basic categories used for selecting desired classifications in advance. The classification axis candidate creation means creates classification axis candidates based on combinations of classifications each correlated to at least one data among descendant classifications of each basic category. The priority calculation means calculates priorities with respect to the classification axis candidates created by the classification axis candidate creation means based on hierarchical distances of classifications in the classified hierarchy.

A data classifier system of the present invention selects a plurality of classifications correlated to data groups so as to output classification axes based on hierarchical classifications and data groups. The data classifier system includes a basic category accumulation means, a classification axis candidate reduction means and a priority calculation means. The basic category accumulation means accumulates classifications serving as basic categories used for desired classifications in advance. The classification axis candidate reduction means selects a plurality of classifications from among classifications descendant from each basic category so as to create classification axis candidates, thus reducing classification axis candidates subjected to calculations based on data quantity of classifications and hierarchical distances of classifications. The priority calculation means calculates priority in displaying classification axis candidates, the number of which is reduced by the classification axis candidate reduction means.

A synonymous expression assessment device includes: synonymy assessment means for receiving input of binary relations each of which includes a nominal and a predicate, and assessing whether or not the input binary relations are synonymous using a similarity between input nominals and a similarity between input predicates; and inter-predicate similarity computation means for, when computing the similarity between the input predicates based on a distribution of occurrence frequencies of nominals that are in binary relations to the input predicate in a document set, performing the computation using a distribution of only nominals that are used in the same type of concept as the input nominal.

Rubber crawler

A field pair as a combination of a definite field and an indefinite field is decided and a correlation value between the definite field and the indefinite field in each of the field pairs is calculated. Among the field pairs in which the correlation value is not smaller than a threshold value, indefinite fields having corresponding definite fields which belong to the same field group are made to be a new field group.

Field correlation method and system, and program thereof

Same document group creation means () acquires a ratio of common words and characters between documents in order to obtain a predetermined similarity greater than a predetermined threshold value between the documents. According to the ratio, words or characters are selected with a common priority in all the documents to be matched. The documents are correlated to the same document candidate group identified by the selected words or characters and stored in a same group candidate group storage unit ().

An object of the present invention is to perform data clustering while preventing the processing speed from decreasing while maintaining accuracy. A block division sectiondivides a block received from a DB access sectioninto sufficiently small blocks. A block storage sectionstores blocks supplied from the block division sectionand hierarchical relationship between the blocks. A block integration sectionintegrates blocks and groups in the order from a hierarchically deeper position to a shallower position based on the stored hierarchical relationship.
