(i) the division result by the first division unit for the region determined as not being in left alignment by the determination unit, and (ii) the division result by the second division unit for the region determined as being in left alignment by the determination unit.

2. The information processing apparatus according to claim 1, wherein the determination unit calculates coordinates of a midpoint of a line indicated by line information on the basis of the line information acquired by the acquisition unit and determines whether or not the region is in left alignment on the basis of one or more of coordinates of a line head, the coordinates of the midpoint and coordinates of a line end of the line in the region.

3. The information processing apparatus according to claim 2, wherein the first division unit divides the region into paragraph regions or itemized regions on the basis of whether or not a character string of one or more characters existing in a line head or a line end satisfies a predefined character string condition.

4. The information processing apparatus according to claim 1, wherein the first division unit divides the region into paragraph regions or itemized regions on the basis of whether or not a character string of one or more characters existing in a line head or a line end satisfies a predefined character string condition.

5. The information processing apparatus according to claim 1, wherein the first division unit divides the region into paragraph regions or itemized regions on the basis of whether or not a value predefined by the number of characters of a line in the region satisfies a predefined condition.

6. The information processing apparatus according to claim 1, wherein the analysis unit analyzes an indent of a line by classifying each line into a line which is indented and a line which is not indented on the basis of a distance from a left end of a region to a left end of each line in the region.

7. The information processing apparatus according to claim 6, wherein the second division unit divides the region into paragraph regions or itemized regions on the basis of whether or not a predefined character string is included in a character string included in a line and whether or not a boundary of the classification which is an analysis result by the analysis unit overlaps a boundary of the paragraph.

8. A non-transitory computer readable medium storing an information processing program causing a computer to function as:

an acquisition unit that acquires, via an image processing device, region information which is information regarding a region in a document, line information which is information regarding a line in the region, and character information which is information regarding a character in the line;

a determination unit that determines whether or not a region including a line indicated by line information is in left alignment on the basis of the line information acquired by the acquisition unit wherein, when a target language of the document is a language which is not regulated such that line ends are aligned, the determination unit changes line information on the basis of character information regarding a character in the next line of a line indicated by the line information and then determines whether or not a region including the line indicated by the line information is in left alignment, and wherein the changes of line information refers to changing information indicating a length of a line in the line information;

a first division unit that divides a region, determined as not being in left alignment by the determination unit, that includes a character indicated by character information into paragraph regions or itemized regions on the basis of the character information acquired by the acquisition unit;

an analysis unit that analyzes an indent of a line in a region determined as being in left alignment by the determination unit;

a second division unit that divides the region determined as being in left alignment by the determination unit on the basis of the analysis result by the analysis unit, into paragraph regions or itemized regions; and

an output unit that outputs both;

(i) the division result by the first division unit for the region determined as not being in left alignment by the determination unit, and (ii) the division result by the second division unit for the region determined as being in left alignment by the determination unit.

9. An information processing apparatus comprising:
