Abstract

An information processing apparatus includes a determination unit and a graph generation unit. The determination unit determines a graph type by analyzing character strings to be presented in an electronic document. The graph generation unit generates a graph of the graph type based on data of the electronic document.

Claims

1. A computer-readable non-transitory storage medium storing therein a graph generation program that causes a computer to perform a procedure comprising:

determining a graph type by analyzing character strings to be presented in an electronic document; and

generating a graph of the graph type based on data of the electronic document.

2. The computer-readable non-transitory storage medium according to claim 1, wherein the determining includes:

specifying a document purpose of the electronic document, based on the character strings in the electronic document; and

determining the graph type based on the document purpose.

3. The computer-readable non-transitory storage medium according to claim 2, wherein the determining includes:

extracting a plurality of specialized vocabulary words from a title of the electronic document; and

specifying the document purpose based on the extracted specialized vocabulary words.

4. The computer-readable non-transitory storage medium according to claim 3, wherein:

each of the plurality of specialized vocabulary words is associated with a vector indicating a specific document purpose of the electronic document; and

the determining includes specifying the document purpose based on an average of the plurality of vectors.

5. The computer-readable non-transitory storage medium according to claim 4, wherein the determining includes:

weighting the plurality of vectors associated respectively with the specialized vocabulary words, depending on word positions within the title at which the specialized vocabulary words appear; and

specifying the document purpose based on the average of the weighted vectors.

6. The computer-readable non-transitory storage medium according to claim 2, wherein the determining includes determining whether the document purpose is comparison of data or analysis of data.

7. The computer-readable non-transitory storage medium according to claim 3, wherein the determining includes:

extracting one of the character strings in the electronic document which satisfies predetermined criteria; and

recognizing the extracted character string as the title of the electronic document.

8. The computer-readable non-transitory storage medium according to claim 1, wherein the determining includes:

determining a number of series of data values to be depicted in a graph in the electronic document, as well as a number of items in each of the series, based on a table in the electronic document; and

determining the graph type, based on the number of series and the number of items.

9. The computer-readable non-transitory storage medium according to claim 8, wherein:

the determining of the graph type includes specifying the document purpose, based on a character string that serves as a title of the electronic document; and

the determining of the number of series is achieved by counting datasets containing a character string that fits the specified document purpose, of all datasets arranged in rows or columns of the table in the electronic document.

10. The computer-readable non-transitory storage medium according to claim 1, wherein the determining includes:

calculating a sum of numerical values of each item; and

specifying the document purpose, depending on whether the calculated sum is 100 in every item.

11. The computer-readable non-transitory storage medium according to claim 1, wherein the procedure further includes:

producing the electronic document, according to style data defining a graph area for accommodating a graph in the electronic document; and

inserting the generated graph in the graph area of the produced electronic document.

12. An information processing apparatus comprising a processor configured to perform a procedure including:

determining a graph type by analyzing character strings to be presented in an electronic document; and

generating a graph of the graph type based on data of the electronic document.

13. A method for producing a graph, the method comprising:

determining, by a processor, a graph type by analyzing character strings to be presented in an electronic document; and

generating, by the processor, a graph of the graph type based on data of the electronic document.
