FIG. 6 is a sequence diagram showing an operation when the stock trading assistance system 10 presents trading candidate brands to the user terminal 7.
The user terminal 7 transmits, for example, the user ID and password input by the user to the sommelier system 1 and logs into the sommelier system 1 (S101).
Next, the user terminal 7 transmits to the sommelier system 1 a search condition including information (preference information) about the user's preference regarding stock trading input by the user (S102). The communication means 17 of the sommelier system 1 transfers the search condition received from the user terminal 7 to the preference engine 2 (S103). Here, the preference information included in the search condition entered by the user includes, for example, interest field information (the industry in which the user is interested, the company name of the company to be supported, etc.), investment policy (high return, low risk, long-term holding, dividend) Gold emphasis etc.). In S103, the preference engine 2 may store the received preference information in the user table 33 in FIG. 4 in order to reuse it.

The database access means 24 of the preference engine 2 transmits an inquiry (query) based on the search condition received from the sommelier system 1 to the theme DB 3, and first tries to select a brand that matches the search condition from the theme DB 3 (S104). . For example, when the preference information included in the received search condition is “ecology” and “high return”, the database access means 16 of the sommelier system 1 searches the company table 31 to find a brand that matches the preference information, For example, “X Corporation” is selected as a trading candidate brand.
Here, the database access unit 24 may search the transaction record table 32 and extract brands with a record of transactions made in the past by the user who logged in at S101.
When an appropriate brand is not hit from the theme DB 3 in S104, or when a certain period has elapsed since the theme DB 3 is updated with respect to the theme of preference information, the database access means 24 of the preference engine 2 is the same as S104. Is transmitted to the brand DB 4 via the network 8 (S105).

The communication means 25 of the preference engine 2 transmits the information received from the theme DB 3 or the brand DB 4 as a response to the inquiry in S104 or S105 to the sommelier system 1 as a trading candidate brand (S106).
When S105 is executed, the database access unit 24 of the preference engine 2 arranges the information collected from the brand DB 4 by theme and stores it in the company table 31 of the theme DB 3 (S107).

The user terminal 7 displays the received information on the display device (S108). The user operates the user terminal 7 to check chart information, analyst information, and the like regarding the trading candidate brand presented from the sommelier system 1.

FIG. 7 is a sequence diagram showing a trading simulation operation of the sommelier system 1.
The user terminal 7 logs into the sommelier system 1 in the same procedure as S101 in FIG. 6 (S111).
The user terminal 7 transmits to the sommelier system 1 an instruction to select a virtual trading stock corresponding to the user's preference input by the user (S112). Examples of instructions include “within 10,000 yen per unit stock”, “low risk”, “high return”, “business content search”, and the like.
Following this instruction, the database access means 16 of the sommelier system 1 collects information on stocks that are trading candidates from the theme DB 3 and the brand DB 4 in the same procedure as S104 and S105 in FIG. 6 (S113), and the collected information is stored in the user. The terminal 7 transmits the information, and the user terminal 7 displays this information on the display device (S114).
The user examines the information displayed on the user terminal 7 in S <b> 114 and inputs the virtual trading brand selected as the target of the virtual transaction to the user terminal 7. The user terminal 7 transmits this information to the sommelier system 1 (S115). The virtual trading execution means 13 of the sommelier system 1 executes virtual trading (S116). In this virtual trading, information (virtual response information) equivalent to the message returned from the online trade system 5 in S125 of FIG. 8 described later is virtually transmitted without transmitting the brand received from the user terminal 7 to the online trade system 5. This is performed by the sale execution means 13 generating. Then, the virtual trading execution means 13 of the sommelier system 1 transmits virtual response information to the user terminal 7 via the communication means 17, and the user terminal 7 displays the received virtual response information on the display device (S117).

The trading execution means 14 of the sommelier system 1 transmits the trading information received from the user terminal 7 to the online trading system 5 (S123), and the online trading system 5 executes actual trading (S124).
When the sale is established, the online trade system 5 transmits the sale execution result to the sommelier system 1 (S125). This information includes, for example, traded brands, the number of shares, and price. The sales execution means 14 of the sommelier system 1 transmits the sales results to the user terminal 7 (S126) and the preference engine 2 (S127) via the communication means 17.
The database access means 24 of the preference engine 2 updates the user table 33 of the theme DB 3 based on the received sales result (S128). This update is performed, for example, by increasing the number of transactions corresponding to a user who has made a sale.
On the other hand, the online trade system 5 stores the contract record in the contract record DB 6 (S129).

According to the stock trading assistance system 10, preference information is stored in the theme DB 3 as investment criteria. The database access unit 24 of the preference engine 2 can search the theme DB 3 and select a sale candidate brand based on preference information.
For this reason, it is possible to select trading candidates in consideration of the investor's subjective judgment criteria of preference information, transmit them to the terminal device, and present them to the investors.

  Since theme information is stored in the theme DB 3 as preference information, the database access means 24 of the preference engine 24 uses the personal interests of each user as a standard, apart from the business category generally used for stock stock classification. Candidate brands can be selected.

  Since the theme DB 3 stores a transaction policy as preference information, the database access means 24 of the preference engine 2 wants an investment policy preferred by each user, for example, “I want to do low-risk transactions”, “I want to hold stock for a long period of time” Candidate brands can be selected according to the policy such as “

  Since the theme DB 3 includes the transaction record table 32, the database access unit 24 of the preference engine 2 selects a brand with a transaction record that is likely to be a brand that matches the user's preference as a candidate for buying and selling. can do.

The stock trading assistance system 10 receives a trading brand that is a brand selected by the user from the trading candidate brands received by the user terminal 7 from the user terminal 7, and transmits the trading brand to the online trade system 5 to place an order.
