Abstract

An information providing server ( 1 ) obtains a message from a poster, converts the posted message such that the amount of information thereof is reduced, based on the level of the amount of information to be transmitted to a viewer, the level being determined depending on the relationship between the poster and the viewer, to thereby generate a converted message, and sends the generated converted message to a user terminal of the viewer.

First claim

1 . An information providing device, comprising:
at least one memory configured to store computer program code; at least one processor configured to access said memory and operate as instructed by said computer program code, said computer program code including: obtaining code configured to cause at least one of said at least one processor to obtain posted information from a poster; conversion code configured to cause at least one of said at least one processor to convert the posted information such that an amount of information of the posted information is reduced, based on a level of an amount of information to be transmitted to a viewer, the level being determined depending on a relationship between the poster and the viewer; and providing code configured to cause at least one of said at least one processor to provide the posted information converted to the viewer.

2 . The information providing device according to claim 1 , further comprising extracting code configured to cause at least one of said at least one processor to extract one or more data elements to be a conversion target from the posted information, wherein the conversion code causes at least one of said at least one processor to reduce an amount of information of each of the data elements extracted, based on the level of the amount of information determined depending on the relationship between the poster and the viewer.

3 . The information providing device according to claim 2 , further comprising a storage that stores conversion rule information that defines a conversion rule for conversion into a plurality of conversion candidates that are different in the level of the amount of information for every kind of data, wherein the conversion code causes at least one of said at least one processor to convert each of the data elements extracted, based on conversion rule information stored in the storage with respect to a kind of that data element and the level of the amount of information determined depending on the relationship between the poster and the viewer.

4 . The information providing device according to claim 1 , further comprising evaluation value obtaining code configured to cause at least one of said at least one processor to obtain an evaluation value indicating closeness in relationship between the poster and each of one or more viewers, wherein the conversion code causes at least one of said at least one processor to convert such that an amount of information of the posted information converted with respect to a first viewer is smaller than an amount of information of the posted information converted with respect to a second viewer when it is determined, based on the evaluation value obtained, that a relationship between the poster and the first viewer is less close than a relationship between the poster and the second viewer.

5 . The information providing device according to claim 4 , wherein the conversion code causes at least one of said at least one processor to convert such that an amount of information of a data element obtained by converting a data element extracted to be a conversion target from the posted information with respect to the first viewer is smaller than an amount of information of a data element obtained by converting a data element as the conversion target with respect to the second viewer when it is determined, based on the evaluation value obtained, that the relationship between the poster and the first viewer is less close than the relationship between the poster and the second viewer.

6 . The information providing device according to claim 4 , wherein the conversion code causes at least one of said at least one processor to extract a larger number of data elements to be a conversion target from the posted information with respect to the first viewer than a number of data elements extracted to be the conversion target from the posted information with respect to the second viewer when it is determined, based on the evaluation value obtained, that the relationship between the poster and the first viewer is less close than the relationship between the poster and the second viewer.

7 . The information providing device according to claim 2 , wherein when the data element extracted is a proper noun, the conversion code causes at least one of said at least one processor to mask or delete a number of letters in a character string included in the data element, the number being determined based on the level of the amount of information determined depending on the relationship between the poster and the viewer, to thereby convert the data element.

8 . The information providing device according to claim 2 , wherein when the data element extracted by the extracting means is address data, the conversion code causes at least one of said at least one processor to delete an address composing segment determined based on the level of the amount of information determined depending on the relationship between the poster and the viewer in an address composing segment included in the data element or replace the address composing segment included in the data element by a superior address composing segment corresponding to the level of the amount of information determined depending on the relationship between the poster and the viewer, to thereby convert the data element.

9 . The information providing device according to claim 2 , wherein when replacement data for replacement depending on the level of the amount of information is defined with respect to the data element extracted, the conversion code causes at least one of said at least one processor to replace the data element by replacement data corresponding to the level of the amount of information determined depending on the relationship between the poster and the viewer.

10 . The information providing device according to claim 2 , wherein when the data element extracted is a motion picture data, the conversion code causes at least one of said at least one processor to convert the motion picture data into a static image included in the motion picture data or attribute information of the motion picture data, depending on the level of the amount of information determined depending on the relationship between the poster and the viewer.

11 . The information providing device according to claim 2 , wherein the extracting code causes at least one of said at least one processor to extract one or more data elements to be a conversion target from among the data elements included in the posted information, depending on priority levels set to respective data elements included in the posted information.

12 . The information providing device according to claim 11 , further comprising:
evaluation value obtaining code configured to cause at least one of said at least one processor to obtain an evaluation value indicating closeness in relationship between the poster and the viewer; and setting code configured to cause at least one of said at least one processor to set a lower priority level to data on a user commonly included in a list of users linked to the poster and a list of users linked to the viewer in selection of a conversion target than a predetermined priority level when the evaluation value obtained with respect to the poster and the viewer is equal to or greater than a threshold or greater than the threshold.

13 . The information providing device according to claim 11 , further comprising:
evaluation value obtaining code configured to cause at least one of said at least one processor to obtain an evaluation value indicating closeness in relationship between the poster and the viewer; and setting code configured to cause at least one
