Method and apparatus for displaying text information and numerical information in association with each other

Abstract

A method and apparatus for associating text information with numerical information. A first phrase corresponding to a time period is generated. The first phase represents a change in first numerical information over the time period. The first numerical information includes time-series data pertaining to a financial index. The text information is retrieved through use of a retrieval condition that includes the first phrase. The first numerical information is retrieved through use of the retrieval condition and the first phrase. The extracted text information and the retrieved first numerical information are outputted in association with each other.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an apparatus and method for displaying text information in association with numerical information.BACKGROUND OF THE INVENTION[0002]In recent years, with the spread of an information-processing apparatus and the development of a communication network, an amount of information that the information-processing apparatus can turn into a target of processing has become enormous. The information that the information-processing apparatus can turn into a target of processing is roughly classified into two types of information, namely, structured information and unstructured information. The structured information includes numerical information such as time-series data, text information classified for every item, or the like. The unstructured information includes text information that is not classified for every item, an image, a voice, or the like. Conventionally, it was difficult to turn the unstructured information into a target ...

AI Technical Summary

Benefits of technology

[0014]The present invention provides an apparatus and method to accurately retrieve text information closely associated with numerical information (e.g., time-series data), and to display the text information in association with the numerical information.

Problems solved by technology

Conventionally, it was difficult to turn the unstructured information into a target of processing as compared with the structured information.

Meanwhile, since the structured information only represents a quantitative fact, it is difficult to grasp a fact from the structured information.

For example, in the time-series data of a stock price, even if a decline in stock price is observed, the reason cannot be grasped.

The structured information may be insufficient for understanding the background fact for this reason, and therefore, the unstructured information, for example, data of newspaper articles or the like is required.
