Abstract

The present disclosure can provide an information processing apparatus capable of increasing the amount of information that can be displayed. The information processing apparatus according to an aspect of the present disclosure includes: a morpheme analysis unit that analyzes a morpheme group included in a document; an importance degree calculation unit that calculates a degree of importance of the morpheme group; and a display period determination unit that determines, based on the degree of importance of the morpheme group, a display period of the morpheme group when the morpheme group is displayed on a display unit.

First claim

What is claimed is:

1. An information processing apparatus configured to,
by executing a program:
analyze a morpheme group included in a document;
calculate a degree of importance of the morpheme group;
determine to continuously display, on a display unit, a morpheme group of which a degree of importance is included in the top-N(N is a natural number) degrees of importance of morpheme groups and to move and display, on the display unit, a morpheme group of which the degree of importance is not included in the top-N degrees of importance of the morpheme groups; and
determine, based on the degree of importance of the morpheme group not included in the top-N degrees of importance of the morpheme groups, a display period of the morpheme group when the morpheme group not included in the top-N degrees of importance of the morpheme groups is displayed on the display unit.

2. The information processing apparatus according to claim 1 ,
further configured to, by executing the program, determine a display size in the following manner: the higher the degree of importance of the morpheme group is, the larger the display size becomes.

3. The information processing apparatus according to claim 1 , further configured to, by executing the program, determine the display position of the morpheme group in the following manner: the higher the degree of importance of the morpheme group is, the closer the display position is to a center of the display unit.

4. The information processing apparatus according to claim 1 , further configured to, by executing the program, determine the display period of the morpheme group not included in the top-N degrees of importance of the morpheme groups in the following manner: the higher the degree of importance of the morpheme group not included in the top-N degrees of importance of the morpheme groups is, the longer the display period becomes.

5. The information processing apparatus according to claim 1 ,
further configured to, by executing the program, determine the display order of the morpheme group in the following manner: the higher the degree of importance of the morpheme group not included in the top-N degrees of importance of the morpheme groups is, the earlier the morpheme group not included in the top-N degrees of importance of the morpheme groups is displayed.

6. The information processing apparatus according to claim 1 , further configured to, by executing the program, determine, based on the degree of importance of the morpheme group, a color of the morpheme group, lightness thereof, a shade thereof, and a font thereof, a thickness of each of characters composing the morpheme group, or a figure that surrounds the characters composing the morpheme group when the morpheme group is displayed on the display unit.

7. An information processing method comprising:
analyzing a morpheme group included in a document;
calculating a degree of importance of the morpheme group; and
determining to continuously display, on a display unit, a morpheme group of which a degree of importance is included in the top-N(N is a natural number) degrees of importance of morpheme groups and to move and display, on the display unit, a morpheme group of which the degree of importance is not included in the top-N degrees of importance of the morpheme groups; and
determining, based on the degree of importance of the morpheme group not included in the top-N degrees of importance of the morpheme groups, a display period of the morpheme group when the morpheme group not included in the top-N degrees of importance of the morpheme groups is displayed on the display unit.

8. The information processing method according to claim 7 , further comprising determining, based on the degree of importance of the morpheme group, a display size of the morpheme group when the morpheme group is displayed on the display unit,
wherein in the determination of the display size of the morpheme group, the display size of the morpheme group is determined in the following manner: the higher the degree of importance of the morpheme group is, the larger the display size becomes.

9. The information processing method according to claim 7 , further comprising determining, based on the degree of importance of the morpheme group, a display position of the morpheme group when the morpheme group is displayed on the display unit,
wherein in the determination of the display position of the morpheme group, the display position of the morpheme group is determined in the following manner: the higher the degree of importance of the morpheme group is, the closer the display position is to a center of the display unit.

10. The information processing method according to claim 7 , wherein in the determination of the display period of the morpheme group not included in the top-N degrees of importance of the morpheme groups, the display period of the morpheme group not included in the top-N degrees of importance of the morpheme groups is determined in the following manner: the higher the degree of importance of the morpheme group not included in the top-N degrees of importance of the morpheme groups is, the longer the display period becomes.

11. The information processing method according to claim 7 , wherein the display period of the morpheme group not included in the top-N degrees of importance of the morpheme groups is a period from when the morpheme group not included in the top-N degrees of importance of the morpheme groups appears from one end of the display unit to when it reaches the other end of the display unit.

12. The information processing method according to claim 7 , wherein a color of the morpheme group, lightness thereof, a shade thereof, a font thereof, a thickness of each of characters of the morpheme group, or a figure that surrounds the characters of the morpheme group is determined based on the degree of importance of the morpheme group when the morpheme group is displayed on the display unit.

13. The information processing method according to claim 7 , further comprising:
calculating a co-occurrence frequency based on the document and the morphemes included in the document; and
forming a subgraph as the morpheme group based on the co-occurrence frequency.

14. A non-transitory computer readable medium storing an information processing program for causing a computer to:
analyze a morpheme group included in a document;
calculate a degree of importance of the morpheme group; and
determine to continuously display, on a display unit, a morpheme group of which a degree of importance is included in the top-N(N is a natural number) degrees of importance of morpheme groups and to move and display, on the display unit, a morpheme group of which the degree of importance is not included in the top-N degrees of importance of the morpheme groups; and
determine, based on the degree of importance of the morpheme group not included in the top-N degrees of importance of the morpheme groups, a display period of the morpheme group when the morpheme group not included in the top-N degrees of importance of the morpheme groups is displayed on the display unit.
