摘要:
A keyword analysis device obtains word vectors represented by the documents by analyzing keywords contained in each of documents input in a designated period. A topic cluster extraction device extracts topic clusters belonging to the same topic from a plurality of documents. A keyword extraction device extracts, as a characteristic keyword group, a predetermined number of keywords from the topic cluster in descending order of appearance frequency. A topic structurization determination device determines whether the topic can be structurized, by segmenting the topic cluster into subtopic clusters with reference to the number of documents, the variance of dates contained in the documents, or the C-value of keyword contained in the documents, as a determination criterion. And a keyword presentation device presents the characteristic keyword group in the subtopic cluster upon arranging the keyword group on the basis of the date information.

An information retrieval apparatus includes a display which displays document information, an input unit which adds additional information to the document information displayed the display, a first storage which stores mark symbol information specifying a particular symbol used for marking, a detector which detects an input from the input unit and decides whether or not the input additional information is identical to or similar to the mark symbol information stored in the first storage, a second storage which stores the mark symbol information and the additional information which is decided that it is similar to the mark symbol information by the detector, associating with the mark symbol information, and a retrieval unit which retrieves the mark symbol information and the additional information associated with the mark symbol information from the second storage, and a retrieval result by the retrieval unit is displayed on the display.
摘要:
Disclosed is an acrylic pressure-sensitive adhesive composition that gives a pressure-sensitive adhesive layer exhibiting superior adhesiveness even to coatings, which are likely to cause low adhesion due to bleeding typically of a surface conditioner, without requiring, for example, washing process.The acrylic pressure-sensitive adhesive composition contains a vinyl monomer or a partial polymer thereof (a); and a (meth)acrylate co-oligomer (b), in which the vinyl monomer contains, as a main component, an alkyl(meth)acrylate monomer (a1) having an alkyl group with 2 to 14 carbon atoms, and the (meth)acrylate co-oligomer (b) has a weight-average molecular weight of from 1000 to 30000 and contains, as monomer components, 96 to 99.5 percent by weight of an alkyl(meth)acrylate (b1) and 0.1 to 4 percent by weight of a (meth)acryloyl group-containing silicone oil (b2).

Disclosed is an acrylic pressure-sensitive adhesive tape or sheet that exhibits satisfactory adhesion to hard-to-adhere adherends.The acrylic pressure-sensitive adhesive tape or sheet includes a microsphere-containing viscoelastic layer (X); and a pressure-sensitive adhesive layer (Y) arranged on at least one side of the viscoelastic layer (X). The pressure-sensitive adhesive layer (Y) is derived from an acrylic pressure-sensitive adhesive composition through the application of an active energy ray, and the acrylic pressure-sensitive adhesive composition contains (a) a vinyl monomer mixture mainly containing an alkyl(meth)acrylate (a1) whose alkyl moiety has 2 to 14 carbon atoms, or a partial polymer of the vinyl monomer mixture; (b) a photoinitiator; and (c) an alkylphenol tackifier. The acrylic pressure-sensitive adhesive composition preferably contains 0.001 to 5 parts by weight of the photoinitiator (b) and 0.01 to 25 parts by weight of the alkylphenol tackifier (c) per 100 parts by weight of the vinyl monomer mixture or a partial polymer thereof (a).
摘要:
A document set, and history documents including documents, etc., browsed by a user are input. The document set and the history documents are each analyzed to obtain characteristic vectors. A plurality of topic clusters and a plurality of sub-topic clusters are obtained by clustering the document set. A transition structure showing transitions of topics among the sub-topic clusters is generated, and a characteristic attribute is extracted from each topic cluster and each sub-topic cluster. An cluster-of-interest is extracted in comparison among characteristic vectors of the history documents and a characteristic vector of each document included in the document set, a sub-topic cluster having transition relations with the cluster-of-interest is obtained on the basis of a transition structure owned by the cluster-of-interest, and a document included in the sub-topic cluster is extracted as a recommended document to be presented together with the characteristic attribute.
摘要:
An action acquiring unit acquires action information corresponding to operation information from a first storage unit for a first user, and stores acquired action information in a third storage unit. A receiving unit receives, via a network, action information of a second user from an external device. A situation acquiring unit acquires, from a second storage, a communication situation corresponding to received action information. A writing unit writes the action information of the first user indicated by the communication situation to the third storage unit, additionally.
