Information processing system

1. An information processing system comprising:

a processor configured to analyze an obtained document, the processor being configured to:

obtain a plurality of documents where information to be shared by a plurality of participants is recorded,

calculate a degree of similarity in details in units of blocks between different documents, the blocks being blocks of sentences included in the documents,

determine an execution order of executing work of sharing details of each of the blocks on the basis of the degree of similarity, and

allocate work time for performing the work of sharing details of each of the blocks on the basis of a number of characters in each of the blocks.

2. The information processing system according to claim 1 , wherein the processor calculates a vector degree of similarity of a document vector representing one or more sentences included in each of the blocks as a vector, and regards the calculated vector degree of similarity as the degree of similarity in details described in each of the blocks.

3. The information processing system according to claim 2 , wherein the processor regards blocks with a highest degree of similarity between different documents as related blocks, and regards one of the related blocks as a target of the sharing work.

4. The information processing system according to claim 3 , wherein the processor regards a block with a lowest degree of similarity among the related blocks as a target of the sharing work.

5. The information processing system according to claim 4 , wherein the processor excludes, among the related blocks, one or more blocks whose degrees of similarity are lower than a predetermined threshold from being a target of the sharing work.

6. The information processing system according to claim 1 , wherein the processor:

relates blocks with a highest degree of similarity between different documents,

presents information indicating relation between the blocks to the participants, and

on receipt of a command from any of the participants, updates the information indicating relation between the blocks.

7. The information processing system according to claim 6 , wherein the processor:

displays, on a display device, a graph in which the blocks are set as vertices and a side is formed between vertices representing the blocks that are related, and

receives an operation performed by any of the participants for replacing the side, and, in accordance with the replaced side, updates the information indicating relation between the blocks.

8. The information processing system according to claim 1 , wherein the processor presents to the participants the execution order and the work time of executing the work of sharing the blocks, and a cumulative value of the work time in a case where the sharing work is executed in the execution order.

9. The information processing system according to claim 8 , wherein the processor distinguishably presents information on one or more blocks of which the cumulative value of the work time is included in a range less than or equal to a predetermined upper limit.

10. The information processing system according to claim 9 , wherein the processor distinguishably presents information on one or more blocks for which the sharing work has been completed.

11. An information processing system comprising:

processing means for analyzing an obtained document, the processing means:

obtaining a plurality of documents where information to be shared by a plurality of participants is recorded,

calculating a degree of similarity in details in units of blocks between different documents, the blocks being blocks of sentences included in the documents,

determining an execution order of executing work of sharing details of each of the blocks on the basis of the degree of similarity, and

allocating work time for performing the work of sharing details of each of the blocks on the basis of a number of characters in each of the blocks.
