Problems solved by technology

[0007] However, in the first technique of presenting the stock price chart and news to the user on the same screen, it is necessary to associate words (hereinafter referred to as words to be extracted from knowledge information) that are objects of insight information such as products in advance with the news. question
[0008] Also, in the second technique of storing, as related products, products that have undergone the same stock price fluctuations at the same time as the product of interest, there is a problem that products that have not undergone the same fluctuations are not associated.
In addition, since items that are explicitly related to the item in the same industry, etc., are set in advance, the scope of grouping items will be limited.
[0009] In the third technology, keyword extraction and category association are performed based on the news stored in the storage device, but the utilization method and update method are not disclosed

no. 1 approach ）

[0066] figure 1 It is a block diagram showing a configuration example of the knowledge extracting device according to the first embodiment. The knowledge extracting device 1 of this embodiment can be used for stock market opening time for systems (compound event processing engines, including engines incorporating CEP, etc.) In the information provision, insight information related to stock trading is extracted from electronic documents such as news information distributed on the Internet or the like. The knowledge information obtained as a result of the extraction can be used for information provision and the like.

[0067] Specifically, when the insight extracting device 1 receives economic news in the news information, for example, it obtains the knowledge of item groupings related to the keyword "influenza", and changes the stock price according to the item related to "influenza". The knowledge of the "mass infection" and "bird flu" of the original material, and maintain ...

no. 2 approach ）

[0182] Next, a second embodiment will be described. In addition, the second embodiment is a modified example related to the knowledge extraction device 1 of the first embodiment that extracts knowledge information on stock trading.

[0183] The direction in which stock prices move may not be consistent with whether newly received information is positive or negative. There is a tendency that the direction of stock price movement is determined by the direction of improvement or the direction of improvement compared with the content predicted in advance by users who trade stocks.

[0184] Therefore, in the first embodiment, in the processing of the information analysis unit 15 , only the presence or absence of the stock price change material and its expression are used as content to be provided to CEP (Complex Event Processing) or the user. However, some stock price fluctuation materials tend to give a certain directionality to stock price fluctuations.

[0185] Therefore, in t...

no. 3 approach ）

[0198] Next, a third embodiment will be described.

[0199] The third embodiment is a modified example of the insight extraction device 1 of the first embodiment for extracting insight information related to stock trading, and the insight information extracted by the insight extraction unit 14 is material (event) related to a certain object and its time. stamp.

[0200] Accordingly, in addition to the above-mentioned function of receiving news information, the information receiving unit 12 further has a function of adding a time stamp to the news information when receiving the news information.

[0201] The insight extracting unit 14 has a function of extracting event information including an expression indicating a predetermined object from the selected news information among the above-mentioned functions of extracting insight information from the news information selected by the information selecting unit 13, and extracting event information from the extracted news informati...

Abstract

Provided are a knowledge extraction device for extracting, from an electronic document that is delivered at any time while not being associated with a knowledge information extraction object, knowledge information relating to the knowledge information extraction object, and a program. A knowledge extraction device of an embodiment is provided with: an information reception unit for receiving an electronic document; a knowledge extraction unit for extracting a concept from the electronic document on the basis of an object word for extracting knowledge information, and a clue word for extracting the knowledge information, and creating the knowledge information in which the extracted concept and the object word are associated with each other; a storage unit for storing the extracted knowledge information; and an information analysis unit for, after the knowledge information is stored, analyzing the electronic document on the basis of the knowledge information in the storage unit.

Description

technical field [0001] Embodiments of the present invention A knowledge extracting device, a knowledge updating device, and a program. Background technique [0002] In order to make effective use of a large amount of data provided by the Internet, etc., there are synonyms related to a certain concept, a dictionary (thesaurus) that defines the relationship between concepts, etc., and the information related to the information required by the user is selected from a large amount of data. , or techniques that combine selected information to provide insights. [0003] For example, in stock trading, it is effective to quickly acquire insight information that can determine the timing of a stock change and reflect it in the transaction content. For example, when a new type of influenza spreads at a time different from usual, it is easy to expect that companies that manufacture masks for infection prevention and companies that manufacture disinfectants will increase demand, and the...
