Information processing device and non-transitory computer readable medium

1. An information processing device comprising:

a processor configured to:

acquire content for which index data is to be created;

divide the content into predetermined blocks;

store unnecessary term information specifying an unnecessary term among terms included in the content, wherein the unnecessary term is a term that is not to be registered in the index data; and

based on the unnecessary term information, determine a region in each block of the content that is not referred to when the index data of the content is created, wherein:

the determined region is separate and distinct from the unnecessary term, and

the determining of the region in a respective block includes:

counting a number of appearances of the unnecessary term in the respective block,

determining whether the counted number is greater than or equal to a preset threshold,

when the counted number is greater than or equal to the preset threshold, determining the region to be an entirety of the respective block, and

when the counted number is less than the preset threshold, determining the region to be a part of the respective block.

2. The information processing device according to claim 1 , wherein the processor is configured to

generate the unnecessary term information in which a term selected by a user from the terms included in the content is set as the unnecessary term.

3. The information processing device according to claim 2 , wherein the processor is configured to

present to the user a term having an appearance frequency equal to or more than a predetermined threshold value among the terms included in the content as a candidate for the unnecessary term.

4. The information processing device according to claim 2 , wherein the processor is configured to

prompt the user to specify the unnecessary term and a weight coefficient of the unnecessary term, and

determine the region in each respective block in accordance with a value calculated by multiplying the number of appearances of the unnecessary term in the respective block by the weight coefficient.

5. The information processing device according to claim 1 , wherein

the determining of the region in the respective block further includes:

determining whether the counted number of appearances of the unnecessary term in the respective block is less than another threshold smaller than the preset threshold, and

when the counted number is less than the another threshold, the region is not specified in the respective block such that the entirety of the respective block is referred to in creating the index data.

6. A non-transitory computer readable medium storing a program that causes a computer to execute information processing, the information processing comprising:

acquiring content for which index data is to be created;

dividing the content into predetermined blocks;

storing unnecessary term information specifying an unnecessary term among terms included in the content, wherein the unnecessary term is a term that is not to be registered in the index data; and

based on the unnecessary term information, determining a region in each block of the content that is not referred to when the index data of the content is created, wherein:

the determined region is separate and distinct from the unnecessary term, and

the determining of the region in a respective block includes:

counting a number of appearances of the unnecessary term in the respective block,

determining whether the counted number is greater than or equal to a preset threshold,

when the counted number is greater than or equal to the preset threshold, determining the region to be an entirety of the respective block, and

when the counted number is less than the preset threshold, determining the region to be a part of the respective block.

7. The non-transitory computer readable medium according to claim 6 , wherein

the determining of the region in the respective block further includes:

determining whether the counted number of appearances of the unnecessary term in the respective block is less than another threshold smaller than the preset threshold, and

when the counted number is less than the another threshold, the region is not specified in the respective block such that the entirety of the respective block is referred to in creating the index data.

8. An information processing device comprising:

acquisition means for acquiring content for which index data is to be created;

division means for dividing the content into predetermined blocks;

storing means unnecessary term information specifying an unnecessary term among terms included in the content, wherein the unnecessary term is a term that is not to be registered in the index data; and

determination means for, based on the unnecessary term information, determining a region in each block of the content that is not referred to when the index data of the content is created, wherein:

the determined region is separate and distinct from the unnecessary term, and

the determining of the region in a respective block includes:

counting a number of appearances of the unnecessary term in the respective block,

determining whether the counted number is greater than or equal to a preset threshold,

when the counted number is greater than or equal to the preset threshold, determining the region to be an entirety of the respective block, and

when the counted number is less than the preset threshold, determining the region to be a part of the respective block.

9. The information processing device according to claim 8 , wherein

the determining of the region in the respective block further includes:

determining whether the counted number of appearances of the unnecessary term in the respective block is less than another threshold smaller than the preset threshold, and

when the counted number is less than the another threshold, the region is not specified in the respective block such that the entirety of the respective block is referred to in creating the index data.
