An information presentation device includes a processor that executes a procedure. The procedure includes: for respective decision making entities, calculating assessment indexes of a plurality of respective assessment criteria, based on characteristic information representing a characteristic of each of the decision making entities; selecting, from the plurality of decision making entities, at least one decision making entity having a characteristic similar to that of an information presentation target decision making entity that is a target of information presentation, based on an assessment index calculated for each of the decision making entities; and acquiring and presenting information related to decision making by the selected decision making entity from a storage section storing information related to decision making for each of the plurality of decision making entities.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. An information presentation method, comprising: for respective decision making entities, calculating, by a processor, assessment indexes of a plurality of respective assessment criteria, based on characteristic information representing a characteristic of each of the decision making entities; selecting, by the processor, from the plurality of decision making entities, at least one decision making entity having a characteristic similar to that of an information presentation target decision making entity that is a target of information presentation, based on an assessment index calculated for each of the decision making entities; and acquiring and presenting, by the processor, information related to decision making by the selected decision making entity from a storage section storing information related to decision making for each of the plurality of decision making entities. 2. The information presentation method of claim 1, wherein a value representing a degree of discrepancy between a target value set for each of the decision making entities according to the characteristics of the decision making entities, and an observed value, is calculated as one of the assessment indexes. 3. The information presentation method of claim 1, wherein a value representing a degree of discrepancy between an observed value for a calculation target decision making entity that is a target of calculation for an assessment index, and a standard value statistically obtained from each of the observed values of the decision making entities included in a decision making entity group that includes a decision making entity other than the calculation target decision making entity, is calculated as one of the assessment indexes. 4. The information presentation method of claim 3, wherein: the decision making entity group is a collection of decision making entities having specific characteristic information similar to that of the calculation target decision making entity; and the standard value is an average value, a maximum value, a minimum value, or a mode value of observed values for the decision making entities included in the decision making entity group. 5. The information presentation method of claim 1, wherein a value representing a change over time in the observed value is calculated as one of the assessment indexes. 6. The information presentation method of claim 1, wherein a value representing a position, in a distribution of observed values for the plurality of respective decision making entities, of an observed value of a calculation target decision making entity that is a target of calculation for an assessment index, is calculated as one of the assessment indexes. 7. The information presentation method of claim 1, wherein, selecting the at least one decision making entity comprises selecting a decision making entity having an assessment index for which a degree of similarity is a specific value or greater. 8. The information presentation method of claim 1, wherein selecting the at least one decision making entity comprises categorizing decision making entities using clustering analysis or a self-organizing map based on an assessment index of each of the decision making entities, and selecting a decision making entity in the same category as the information presentation target decision making entity. 9. The information presentation method of claim 1, wherein the information related to decision making includes at least one of a success case, a failure case, decision making content, a budget allocation, an organizational framework, or an actual result of decision making when a decision was made. 10. The information presentation method of claim 1, wherein, for an environmental valuation, a societal valuation, a fiscal valuation, and an environmental impact held by a decision making entity, when a valuation of the decision making entity is denoted Vi, valuation categories are denoted i, a weight coefficient for each valuation category is denoted wi, a summed valuation of the decision making entity is denoted Vtotal, an environmental impact of the decision making entity is denoted Bj, environmental impact categories are denoted j, a weight coefficient for each environmental impact category is denoted gj, and a summed environmental impact is denoted Btotal, a value representing the sustainability of the decision making entity is computed as the characteristic information in the decision making entity using the equation Vtotal/Btotal (where, Vtotal=ΣwiVi and Btotal=ΣgjBj). 11. The information presentation method of claim 10, wherein the environmental valuation includes at least a land criterion, a water criterion, and an atmosphere criterion. 12. The information presentation method of claim 10, wherein the societal valuation includes at least a housing criterion, a food criterion, a traffic criterion, a safety criterion, an education criterion, a medical care criterion, and a government criterion. 13. The information presentation method of claim 10, wherein the fiscal valuation includes at least a finance criterion, an employment criterion, and an individual economic power criterion. 14. The information presentation method of claim 10, wherein the environmental impact includes at least a climate change related criterion, a resource recycling related criterion, and a biodiversity related criterion. 15. An information presentation device, comprising: a memory configured to store information related to decision making for each of a plurality of decision making entities; and a processor configured to execute a process, the process comprising: for respective decision making entities, calculating assessment indexes of a plurality of respective assessment criteria, based on characteristic information representing a characteristic of each of the decision making entities; selecting, from the plurality of decision making entities, at least one decision making entity having a characteristic similar to that of an information presentation target decision making entity that is a target of information presentation, based on an assessment index calculated for each of the decision making entities; and acquiring and presenting information related to decision making by the selected decision making entity from the memory. 16. A non-transitory recording medium storing an information presentation program executable by a computer to perform a process, the process comprising: for respective decision making entities, calculating assessment indexes of a plurality of respective assessment criteria, based on characteristic information representing a characteristic of each of the decision making entities; selecting, from the plurality of decision making entities, at least one decision making entity having a characteristic similar to that of an information presentation target decision making entity that is a target of information presentation, based on an assessment index calculated for each of the decision making entities; and acquiring and presenting information related to decision making by the selected decision making entity from a storage section storing information related to decision making for each of the plurality of decision making entities.
