## Abstract

The present technology relates to an information processing apparatus, an information processing method, and a program allowing a user to access a reference document or the like written inside an electronic document by only clicking on a description of the reference document. A storing unit that stores information of an electronic document, an extraction unit that extracts a sentence including the information stored in the storing unit from a predetermined electronic document, and a generation unit that generates a link to the information stored in the storing unit from the sentence extracted by the extraction unit are provided. Even in a case where the electronic document is a document that is formed as the electronic document through scanning, when the degree of matching between the sentence included in the electronic document and the information stored in the storing unit is high, the sentence and the information are associated with each other, and a link is established. The present technology can be applied to a terminal handling electronic books.

## Claims

### Claim 1

An information processing apparatus comprising:
a storing unit that stores information of an electronic document;
an extraction unit that extracts a sentence including the information stored in the storing unit from a predetermined electronic document; and
a generation unit that generates a link to the information stored in the storing unit from the sentence extracted by the extraction unit.

### Claim 2 (depends on 1)

The information processing apparatus according to claim 1,
wherein the storing unit includes a first storing unit in which the information of the electronic document stored in the same terminal is stored and a second storing unit in which the information of the electronic document stored in the other terminal is stored, and
the extraction unit extracts a sentence including the information stored in the first storing unit from a predetermined electronic document and extracts a sentence including the information stored in the second storing unit from a predetermined electronic document.

### Claim 3 (depends on 1)

The information processing apparatus according to claim 1, wherein the electronic document is acquired by digitizing a document that is printed on a paper medium.

### Claim 4 (depends on 1)

The information processing apparatus according to claim 1,
wherein the extraction unit calculates a first degree of similarity between a predetermined sentence included inside the electronic document and the information stored in the storing unit,
calculates a second degree of similarity between a sentence acquired by combining the predetermined sentence and a sentence next to the predetermined sentence and the information stored in the storing unit,
repeatedly performs the combining of sentences and the calculating of the degree of similarity until the second degree of similarity is determined to be higher than the first degree of similarity, and
sets the sentence before the combination as an extraction result when the second degree of similarity is determined to be lower than the first degree of similarity.

### Claim 5 (depends on 1)

The information processing apparatus according to claim 1,
wherein the extraction unit further extracts a number making reference to the extracted sentence from the predetermined electronic document, and
the generation unit gives the link generated for the sentence that is referred to by the number to the number extracted by the extraction unit.

### Claim 6 (depends on 1)

The information processing apparatus according to claim 1, wherein an update process is performed by extracting a sentence including updated information from the predetermined electronic document in a case where storing unit is updated.

### Claim 7

An information processing method using an information processing apparatus equipped with a storing unit that stores information of an electronic document, the information processing method comprising:
extracting a sentence including the information stored in the storing unit from a predetermined electronic document; and
generating a link to the information stored in the storing unit from the extracted sentence.

### Claim 8

A computer-readable program causing a computer that controls an information processing apparatus equipped with a storing unit storing information of an electronic document to perform:
extracting a sentence including the information stored in the storing unit from a predetermined electronic document; and
generating a link to the information stored in the storing unit from the extracted sentence.
