Description

This invention relates to an information retrieval system, an information retrieval device, an information retrieval method, and a program. With the advancement of digitalization, including AI (Artificial Intelligence) and IoT (Internet of Things), how to utilize this information is becoming crucial to corporate management activities, and information analysis itself is becoming linked to a company's competitiveness. For example, Patent Document 1 discloses a technology that collects or searches information such as trends in a company's business schedule and development schedule, market size, profits and sales for each of its products, and patent information (such as patent registration records) of both the company and other companies for a period requested by the user, and displays this information arranged on a timeline. Japanese Patent Publication No. 2019-82858 A schematic block diagram showing an example of the configuration of an information retrieval system according to the embodiment.A diagram showing an example of the hardware configuration of a terminal according to this embodiment.A diagram showing an example of the hardware configuration of an information retrieval device according to the present invention.A diagram illustrating the overview of the information retrieval process according to the embodiment.A block diagram showing an example of the functional configuration of an information retrieval device according to this embodiment.A figure showing a detailed example of the first part of the information retrieval process according to the embodiment.A figure showing a detailed example of the second part of the information retrieval process according to the embodiment.A diagram showing a detailed example of the third part of the information retrieval process according to the embodiment. Embodiments of the present invention will be described in detail below with reference to the drawings. (System configuration) Figure 1 is a schematic block diagram showing an example of the configuration of the information retrieval system 1 according to this embodiment. The information retrieval system 1 comprises a plurality of terminals 10 (10-1, 10-2, ...) and an information retrieval device 20. Each of the plurality of terminals 10 is connected to the information retrieval device 20 via a network NW. The information retrieval system 1 also communicates with external devices such as a finance information provision server 30, a search server 40, a corporate information provision server 50 (50-1, 50-2, ...), and a patent search server 60 via a network NW. The network NW is a communication network such as a WAN (Wide Area Network) including the Internet or a mobile phone communication network, or a LAN (Local Area Network) using wired or wireless connections. The finance information server 30 extracts finance information stored in the finance information database 31 according to search criteria and transmits the extracted finance information to the terminal 10 or information retrieval device 20 via the network NW. The finance information database 31 stores publicly available finance information, such as stock information. For example, the finance information server 30 extracts and transmits stock information ranked based on the input search criteria (hereinafter referred to as "stock information ranking"). The search server 40 provides a search service using a search engine that retrieves information obtainable via a network (such as the internet). For example, the search server 40 searches for information obtainable via the network (e.g., websites, web pages) based on the entered search term and outputs the search results. The search server 40 also stores a history of entered search terms. For example, the search server 40 has a suggestion function that outputs words closely related to the entered search term based on the history of previous search terms. Words closely related to the entered search term are words that have been searched together with the entered search term. The more often a word has been searched together, the more closely related it is considered. The corporate information server 50 stores data from corporate websites and, in response to requests from terminals 10 or information retrieval devices 20, transmits corporate information and other data contained in the corporate websites to the requesting party via the network NW. For example, corporate information may include IR (Investor Relations) information. The corporate information server 50 may store data from multiple corporate websites. Furthermore, while the illustrated example shows one corporate information server 50, multiple corporate information servers 50 may each store data from one or more corporate websites. The patent search server 60 extracts patent information stored in the patent information database 61 according to the search criteria and transmits the extracted patent information to the terminal 10 or information retrieval
