A document classifying device () includes: a unit () configured to acquire information regarding a to-be-classified document set in which classification codes based on multi-viewpoint classification are assigned to each document in advance; a unit () configured to generate a multi-dimensional feature vector for each document in the to-be-classified document set, the multi-dimensional feature vector having, as elements, all or part of the classification codes assigned to the to-be-classified document set; classifying unit () configured to classify the to-be-classified document set using the feature vector of each document; and a generating unit () that generates document classification information indicating a result of the classification.

Document classifying device

An absorbent articlehas an extensible absorbent memberand is extensible as a whole. The absorbent memberhas three-dimensionally dispersed therein a large number of small absorbent clustersorcontaining a superabsorbent polymerand fibers. The small clustersorare dispersively arranged in a web containing crimped fibers. The small clusters include those composed of a superabsorbent polymer particleand a large number of fibersadhered to the particleand those composed of a helically crimped fiber, a superabsorbent polymer particle, and fibers, the polymer particleand the fibersbeing taken into the helix of the crimped fiber

Absorbent article

A nonwoven fabrichas a first layercontaining crimped fibers. In the layer, the crimped fibers gather in parts to form a large number of fiber clustersthat are distributed all over the layer. The clustersinterconnect to each other to form a network structure in the layer. The nonwoven fabricfurther has another fiber layer as a second layerdisposed on a side of the first layer. The two layers are partly joined at a large number of joints. The second layerprotrudes outwardly between the jointsto form a large number of protrusions

Nonwoven fabric and process of producing the same

An absorbent article having a topsheet, a backsheet, and an absorbent memberinterposed between the topsheetand the backsheetis disclosed. The absorbent memberhas a number of compressed partswhich are discrete from one another and concave on the backsheet facing side and/or the topsheet facing side. The compressed part is configured to increase in thickness on absorbing liquid. The compressed part is made up of a thinnest portionand a sloping portion. The sloping portion a gradually changes in thickness to connect to the thinnest portion

A fibrous sheet containing cotton fibers and at least two kinds of synthetic fibers is disclosed. The synthetic fibers form a nonwoven fabric. The cotton fibers enter a fiber network of the nonwoven fabric and interlace with the fiber network thereby to form a cotton fiber layer on one side of the nonwoven fabric, with part of the cotton fiber layer entering the nonwoven fabric. The synthetic fibers contain a combination of heat fusible fiber (a) and heat fusible fiber (b) having a small thickness than the fiber (a) or a combination of the fiber (a) and a fiber (c) that is not thermally bonded with the fiber (a).

Fibrous sheet

An absorbent article having a substantially oblong rectangular absorbent body A composed of a topsheet, a backsheet, and an absorbent corebetween the topsheetand the backsheet. The absorbent article further has a pair of side sheetsas leak preventive side members on its skin facing side C of the absorbent body A. The leak preventive side members have a pattern P printed with ink in a configuration such that the printed ink is substantially kept away from contact with the skin of a wearer.

A sheet which gives an absorbent article improved recovery from distortion is disclosed. The sheet has a recovery force of 0.7 cN or more in the cross direction, a compressive strength of 100 cN or less, and a basis weight of 20 g/mor more.
