Information providing system, information providing method, and program
View Patent ↗Provided are providing an ECG unit which is formed of content information and related information related thereto, and is linked to another ECG unit through the related information, calculating an association-degree score between the pieces of content information based on a degree of association of an attribute between the pieces of content information, collecting a history of operation performed for making a transition from a link-source-ECG unit to a link-destination-ECG unit, as a usage log of the ECG unit, calculating a transition score between the ECG units in a manner that a weight of a larger correction coefficient is assigned to a number of usage logs, as there are more attributes of content information having low degree of association with each other between the link-source-ECG unit and the link-destination-ECG unit, and generating an ECG unit linked to another ECG unit, based on the association-degree score and the transition score.
1. An information providing system comprising:
circuitry configured to operate as
a content unit providing section which provides a content unit, the content unit being formed of content information and one or more pieces of related information related to the content information, and being linked to another content unit through the related information;
an association-degree score calculation section which calculates an association-degree score between the pieces of content information based on a degree of association of an attribute between the pieces of content information;
a usage log collection section which collects a history of operation performed for making a transition from one or more content units of link sources to one or more content units of link destinations via the content unit, as a usage log of the content unit;
a transition score calculation section which calculates a transition score between the content units based on a corrected usage log which is obtained by applying a correction coefficient to the usage log, the correction coefficient based on a number of attributes of content information and a degree of association with each other between the content unit of the link source and the content unit of the link destination; and
a content unit generation section which generates a content unit linked to another content unit, based on the association-degree score between the pieces of content information and the transition score between the content units.
2. The information providing system according to claim 1 ,
wherein the correction coefficient is set by a user.
3. An information providing method comprising:
providing a content unit, the content unit being formed of content information and one or more pieces of related information related to the content information, and being linked to another content unit through the related information;
calculating an association-degree score between the pieces of content information based on a degree of association of an attribute between the pieces of content information;
collecting a history of operation performed for making a transition from one or more content units of link sources to one or more content units of link destinations via the content unit, as a usage log of the content unit;
calculating a transition score between the content units based on a corrected usage log which is obtained by applying a correction coefficient to the usage log, the correction coefficient based on a number of attributes of content information and a degree of association with each other between the content unit of the link source and the content unit of the link destination; and
generating a content unit linked to another content unit, based on the association-degree score between the pieces of content information and the transition score between the content units.
4. A non-transitory computer readable medium having stored thereon a program for causing a computer to execute an information providing method, said method comprising:
providing a content unit, the content unit being formed of content information and one or more pieces of related information related to the content information, and being linked to another content unit through the related information,
calculating an association-degree score between the pieces of content information based on a degree of association of an attribute between the pieces of content information,
collecting a history of operation performed for making a transition from one or more content units of link sources to one or more content units of link destinations via the content unit, as a usage log of the content unit,
calculating a transition score between the content units based on a corrected usage log which is obtained by applying a correction coefficient to the usage log, the correction coefficient based on a number of attributes of content information and a degree of association with each other between the content unit of the link source and the content unit of the link destination; and
generating a content unit linked to another content unit, based on the association-degree score between the pieces of content information and the transition score between the content units.
