Abstract: A plurality of pieces of send candidate information are stored (S12). Each piece of send candidate information has sender identification information identifying a sender of an email, recipient identification information identifying a recipient of the email, item identification information (52b and 52c), item information that are associated with each other. The item information includes element values of one or more elements. From among the stored pieces of send candidate information, two or more pieces of send candidate information that have different pieces of sender identification information, the same recipient identification information, and related pieces of item identification information are extracted (S13).

Abstract: The information providing system includes the communication unit, the content database, the search unit and the map information generation unit. The communication unit acquires place information indicating a place. The content database stores place information indicating a place and specifying information specifying an expression part where an expression related to the place appears in content in association with each other. The search unit acquires the specifying information stored in association with the place information indicating a place within a specified range from the place indicated by the place information acquired by the communication unit from the content database. The map information generation unit outputs the specifying information acquired by the search unit.

Abstract: A plurality of pieces of send candidate information are stored (Step S12). Each piece of send candidate information has recipient identification information identifying a recipient of an email and an email substance (50 and 55) that are associated with each other. The email substance includes a plurality of components (51, 52, and 53). From among the stored pieces of send candidate information, two or more pieces of send candidate information that have the same recipient identification information and at least one of the components related between their email substances are extracted (S13, S14, and S15). An email substance (56) to be sent to the recipient is generated, based on common components related between the email substances of the extracted pieces of send candidate information and on components that are included in the email substances of the extracted pieces of send candidate information and that are other than the common components (S16).

Abstract: An information providing device includes a memory storing program code and a processor operating as instructed by the program code. The program code includes: reception code configured to cause the processor to receive, from a user terminal displaying a first page, a page request for access to a second page, the page request including a user ID; search code configured to cause the processor to create a query including an additional condition extracted based on the page request and the user ID, and then use the created query to search a purchase history database in order to identify a product corresponding to the query; extraction code configured to cause the processor to extract product detail information of the identified product; and transmission code configured to cause the processor to transmit the second page to the user terminal and transmit the product detail information to the user terminal or another server.

Abstract: An information providing device according to an aspect comprises: a reception unit which receives a page request for access to a web page of an auction site from a user terminal, the page request containing an identifier for specifying a user; a search unit which extracts a purchase history corresponding to the identifier from a purchase history memory storing purchase histories of products and which specifies a product having been purchased by the user and corresponding to a content of the web page; and a transmission unit which transmits product information and the web page to the user terminal in order to display the product information of the product specified by the search unit, along with the web page on the user terminal in a state in which the user can display the product for auction at the auction site.

Abstract: To provide a post display system, a post display method and a post display program capable of avoiding giving away the content even when a spoiler is posted, a reading terminal (1) functions as a post display system for displaying posted information posted for an electronic book and includes a terminal page management unit (12) and a display restriction unit (14). The terminal page management unit (12) specifies an unread part of the electronic book not read by a user who reads the posted information. The display restriction unit (14) performs control to impose display restrictions on posted information associated with the unread part among posted information associated with any part of the electronic book. An unread part not read by a user is thereby specified, and display restrictions are imposed on posted information associated with the unread part among posted information associated with any part of the electronic book.

Abstract: A web server 40 includes a keyword acquisition unit (43) that acquires first item information related to a first item shown on a web page displayed on a web browser of a user terminal (10), a related item acquisition unit (44) that acquires second item information indicating a second item (related item) related to the first item by referring to an item database (21) storing item information based on the first item information, and a related item transmitting unit (45) that transmits the second item information to the user terminal (10) so that the second item information is shown in a separate window displayed superimposed on the web page.
