When no past case exists in the target area, the logic is changed based on the past case of the similar city.

  The information sharing apparatus of the present embodiment is useful when it is necessary to appropriately provide the necessary information of the user during the time when the information is confused, such as in the event of a disaster. For example, immediately after a disaster occurs, even if the user tries to obtain information necessary for disaster response, if the information itself does not exist, if the information exists but it has not been published by a predetermined organization, the user There are cases where it cannot be found. Further, even if the user obtains the information, the obtained information cannot be used as it is, and it may be necessary to edit the information. Further, even when a user can use a lot of information, there is a case where it is difficult to determine which information should be selected because there is too much information. In such a situation, the information sharing apparatus of the present embodiment automatically selects the information necessary for the user, and if there is no information necessary for the user, provides it by inferring it by combining other related information. . Furthermore, the information sharing apparatus according to the present embodiment can update the logic based on past actual data. If the set logic is incorrect, or if an unexpected event occurs due to changes in the environment such as climate or urban structure, it is possible to update the logic close to the actual data based on the past actual data. If there is no past case in the target area, the logic is updated based on the past case in the similar city. Since the logic can be updated based on past cases, it is possible to continue to provide the user with information that is in line with the facts according to changes in the environment.

<Processing procedure>
Next, the information providing process executed by the information sharing apparatus 1 will be described.

  FIG. 12 is a flowchart of the information providing process.

  First, in step S101, the information selection unit 1111 receives information (hereinafter, referred to as input information) such as work and disaster type from the information use device 4.

  In step S102, the information selection unit 1111 selects one or more pieces of provision information necessary for performing the work based on the input information received from the information utilization device 4, and outputs the provision information ID. It should be noted that a plurality of pieces of provision information may be selected. In step S102, the information selection unit 1111 associates the information category ID, which is the ID of the information category indicating the classification of the provided information, the priority defining the priority order to be presented to the user, and the provided information ID in association with each other. May be output to. Here, the priority includes the priority indicating the strength of the relationship between the business and the provided information. When the number of pieces of provision information to be output in step S102 is large, the information selection unit 1111 may narrow down the number of pieces of provision information to be output based on the priority.

  For example, in step S102, the information selection unit 1111 selects the provision information ID by outputting the selected provision information ID by searching the information selection table T121 in FIG. 5 using the task and disaster type of the input information. To do. For example, when the input information includes “G-001” as the business ID, the information selection unit 1111 determines that the provided information ID is “I-001”, “I-002”, “I-003”, “I”. -004 "," I-005 ", and" I-006 "are output. When outputting the priority together with the provided information ID, the information selection unit 1111 outputs the priority corresponding to “I-003” as “2” as the priority of each provided information ID, "1" is output as the priority corresponding to other than that.

  In step S103, the information selection unit 1111 selects one or more information items that match the disaster type input in step S101 with respect to the provided information ID output in step S102, and a data ID indicating the information item. Of the provided information indicating whether the information item generation processing is performed and whether the provided information to be output is the finalized information published by a public organization or the estimated information estimated by the information sharing apparatus 1 or the like. The type and the display format of the provided information are output. In step S103, the information selection unit 1111 may also output the priority defining the priority order of the information items with respect to the provided information. Further, when there are many information items to be output, the information selection unit 1111 may narrow down the number of information items to be output based on the priority.

  For example, the information selection unit 1111 selects the data ID by searching the information generation model table T122 in FIG. 6 using the provided information ID output in step S102 and the disaster type input in step S101 as keys. . Then, the information selection unit 1111 outputs the presence / absence of generation processing, the type of provided information, and the display format corresponding to the selected data ID. In the example of FIG. 6, when the provided information ID output in step S102 is “I-001” and the disaster type input in step S101 is “heavy rain”, the data ID output from the information selection unit 1111. The combinations of the presence / absence of generation processing, the type of provided information, and the display format are “MJ-001, nothing, confirmed, line”, “MJ-002, nothing, confirmed, line”, “SJ-001, Yes, guess, line ”,“ SJ-002, Yes, guess, line ”.

  In step S104, the information generation unit 113 determines whether or not the generation process output in step S103 is present, and if the generation process is set to “present” (S104: YES), the process proceeds to step S105, and the generation process is performed. If is set to "none" (S104: NO), the process proceeds to step S106. For example, taking the information generation model table T122 of FIG. 6 as an example, when the data ID is “MJ-001”, the generation process is set to “absent”, so the information generation unit 113 performs the process in step S106. Proceed to. On the other hand, when the data ID is “SJ-001”, the generation process is set to “present”, and the information generation unit 113 advances the process to step S105. Therefore, in step S104, if the information item output in step S103 is the original data itself, the process proceeds to step S106, and if the generation process is required instead of the original data, the process proceeds to step S105. .

  In step S105, the data extraction unit 1112 generates one or more information items from among the information items output in step S103 for those that require generation processing (those set to “Yes”). The data, the presence / absence of integration processing for the original data, the presence / absence of generation processing for the original data, and the logic of the generation processing are output. For example, the data extraction unit 1112 selects one or more original data by searching the information generation logic table T123 of FIG. 7 using the data ID output in step S103 as a key, and selects the original data data ID. , Necessity of integration processing, presence / absence of generation processing, and logic ID are output. For example, if the data ID output in step S103 is "SJ-001", the data extraction unit 1112 outputs "MJ-005" and "KJ-001" as the data ID of the original data, and the integration processing is performed. “Necessary” is output as “necessary” and “Yes” is output as the presence / absence of generation processing, and “L-001” is output as the logic ID.

  In step S106, the data extraction unit 1112 uses the data ID of the original data that forms the information item output in step S103 or step S105 and uses the data ID of the information item or original data from the information storage unit 22 (hereinafter referred to as data). To extract. For example, when extracting the original data of the road traffic availability information_DiMAPS damage report as an information item, the data extraction unit 1112 searches the metadata management table T124 of FIG. 8 using the data ID “MJ-001” as a key. Then, the storage destination “JK-001” in the information storage unit 22 is specified, and the corresponding data is extracted from the information storage unit 22. If there is no information, the data extraction unit 1112 outputs data indicating that it has not been obtained (for example, "Null") and does not execute the processing steps after step S107. Since various data have different data formats (CSV, XML, JSON, etc.) depending on the providers, the formats may be centrally unified at the time of data extraction. Alternatively, the formats may be unified when the data is integrated and generated in step S108 and step S109 described later.

  In step S107, the information generation unit 113 determines whether or not integration processing is necessary for the data extracted in step S106. If the integration process is not necessary (S107: NO), the information generation unit 113 advances the process to step S109, and if the integration process is necessary (S107: YES), the process advances to step S108. In step S107, the information generation unit 113 uses the information generation logic table T123 of FIG. 7, for example, to determine the necessity of integration processing. If the data ID is “SJ-001”, the integration process is set to “necessary”, and the information generation unit 113 advances the process to step S108. If the data ID is “SJ-004”, the integration process is set to “unnecessary”, and the information generation unit 113 advances the process to step S109.

  In step S108, the information generation unit 113 integrates the original data extracted in step S106 and creates information items by integrating the original data. For example, the information generation unit 113 uses the information generation logic table T123 of FIG. 7 to superimpose a plurality of original data on one information item to generate an information item. For example, when the information item is “road traffic availability information_estimated inundation range” (data ID “SJ-001”), the information generation unit 113 uses the “GSI estimated inundation range” and “road infrastructure map” of the original data. “MJ-005” and “KJ-001” which are data IDs of “,” are used as keys to read the respective original data, and the original data are overlapped with each other, and based on the logic, “road traffic availability information_estimated inundation range” Is generated.

  In step S109, the information generation unit 1113 uses the data extracted in step S106 or the information item generated in step S108 to perform integration processing or generation processing to generate map information and generate provision information. For example, by using the information generation model table T122 of FIG. 6, in step S108, “road traffic availability information_DiMAPS damage report (MJ-001)” and “road traffic availability information_construction regulation information (MJ-002)” are obtained. In the case of outputting, the information generation unit 1113 superimposes and integrates the “road traffic availability information_DiMAPS damage report (MJ-001)” and the “road traffic availability information_construction regulation information (MJ-002)”, and “ This is the final information of the road traffic availability information (I-001) ”. Next, the information generation unit 1113 converts the information into map information, which is provided information.

  In step S110, the information providing / display unit 1114 converts the content and format of the information according to the user in order to provide the provided information generated in step S109 to the information utilization apparatus 4 and the information display unit 115, and The provided information is displayed on the display screen of the utilization device 4 or the information display unit 115. For example, the information providing / display unit 1114 creates map information and character information according to the user, and changes the information format (XML, CSV, JSON) according to the user's information utilization device 4, The display method, content, and format of the information are changed according to the user, the information is converted into the content and format that the user can easily use, and the provided information is output on the display screen.

  Here, the information sharing apparatus 1 accepts the input of data of various formats provided from the information supply apparatus 3, unifies the data formats, and changes the provided information to various formats according to the information utilization apparatus 4 of the user. Convert and provide information. For example, in order to share information between information providers (A institutions) and information users (B institutions), it is necessary to build an A × B system. Since the format is converted, the information sharing apparatus 1 can be used to build an A + B system, and both the provider and the user can use the existing system, and the cost and man-hours can be reduced.

  In step S111, it is determined whether or not there is a change request from the user for the provision information output to the information utilization device 4 or the information display unit 115 in step S110. When the logic and data changes are input by the user (S111: change (data)), the information provision / display unit 1114 advances the process to step S108 to generate provision information using the newly input data and logic. Perform processing to When the user inputs only the change of the logic (S111: change (only the logic)), the information providing / display unit 1114 advances the process to step S109 to generate the provided information with the newly input logic. Perform processing to If addition of additional information is input by the user (S111: addition), the information providing / display unit 1114 advances the process to step S102, and performs extraction and providing processing for the added new additional information. If the user requests deletion of the provided information (S111: Delete), the information providing / display unit 1114 advances the process to step S112, and cancels the display of the provided information from the screen. On the other hand, if there is no change request from the user (S111: None), the information provision / display unit 1114 advances the process to step S113.

  In step S112, the information providing / display unit 1114 performs a process of canceling the display on the screen of the information utilization device 4 and the information display unit 115 for the provided information requested to be deleted by the user, and then the process proceeds to step S111. return.

  In step S113, the provision information management unit 1115 stores the provision information output in step S110 in the provision information table T125, and outputs the information in which the type of provision information is definite among the provision information output in step S110 as a result. Store in table T127. With the above processing, it is possible to provide appropriate information to the information utilization device 4.

  The information providing process shown in FIG. 12 may be performed regularly, for example, every hour or every 30 minutes, or at the timing when the information collecting device 2 obtains the new original data. You may make it implement. Furthermore, the periodical implementation and the implementation when a predetermined timing occurs may be combined and executed. As a result, when the situation changes momentarily due to a disaster, etc., when new information (original data) is obtained, information is updated, or the situation or environment changes, the situation is changed. It becomes possible to provide the latest information according to the requirements.

  Next, the logic correction processing executed by the information sharing apparatus 1 will be described.

  FIG. 13 is a flowchart of the logic correction process.

  First, in step S201, the logic changing unit 1124 inputs a logic changing region (target region), information (target information), and disaster (input information) to the screen displayed on the information utilization device 4 or the information display unit 115. (Target disaster).

  In step S202, the result extraction unit 1121 extracts information (provided information) generated and provided by the information sharing apparatus 1 with respect to the target area, the target information, and the target disaster whose logic is accepted in step S201. . For example, the result extraction unit 1121 searches the provision information table T125 of FIG. 9 and uses the city name or latitude / longitude, the provision information (or provision information ID), and the disaster type (or disaster ID) as keys to select the disaster name. , Disaster type, city name, destination, business, provided information, provided information type, information item, latitude / longitude, information provided date / time, data acquisition date / time, data aggregation date / time.

  In step S203, the result extraction unit 1121 does not generate past fact data of the target information at the time of the target disaster existing in the target area acquired in step S201 (the information sharing device 1 does not integrally generate damage data and result data). (Determined data) is extracted. The result extraction unit 1121 uses, for example, the result table T127 of FIG. 11, with the latitude / longitude or city name, the provided information, and the past event as keys, the result ID, date and time of occurrence, city name, latitude / longitude, cause, The scale, provided information, information name, result, and storage destination are specified. Next, the result extraction unit 1121 extracts data from the information storage unit 22 using the specified storage destination as a key. The result extraction unit 1121 uses the provision information table T125 in FIG. 9 and the metadata management table T124 in FIG. 8 to select the city name (or city ID) and the target disaster in which the target area is included in the provision information table T125. Corresponding to the disaster type (or disaster ID) that matches with, there is provided information that matches the target information, and the information item (or data ID) whose provided information type is “confirmed” is specified, and metadata management is performed. The storage destination may be specified using the table T124, and the data may be extracted from the information storage unit 22 using the specified storage destination. Further, when there is no actual data in the target area, the result extraction unit 1121 may extract the actual data from the vicinity of the target area or a city including the target area. If the actual data cannot be extracted in the target area, the area around the target area, and the city including the target area, the result extraction unit 1121 outputs data indicating that the actual data has not been obtained (for example, “none”). The process of this step is completed, and the process proceeds to step S204.

  In step S204, the result extraction unit 1121 determines the presence or absence of the actual data output in step S203, and if it is set to “present” (S204: YES), the process proceeds to step S207 and set to “not present”. If so (S204: NO), the process proceeds to step S205.

  In step S205, the similar city search unit 1122 searches for a city in which the condition that is a factor of the provision information is similar to the target area and which holds the past provision information of the target information. Here, the similar city is a city that is close to the target area in conditions of disaster occurrence and conditions that are factors of information provided such as climate, population, geography, and industry. A similar city to the target city may be determined in advance, a neighboring city in the same prefecture as the target city may be set as the similar city, or the information sharing device 1 may calculate the similar city. Good. In step S205, the similar city search unit 1122 uses, for example, the city model table T126 of FIG. 10, to find similar city candidates whose condition that is a factor of the target information is close to the target city including the target area. One or more are calculated in order from the closest to the target city, and the candidate city name (or city ID) of the similar city is specified. Next, the similar city search unit 1122, for example, using the result table T127 of FIG. 11, with the city name (or city ID) of the identified candidate of the similar city as a key, sets the target information to the candidate city of the similar city. Of the past provision information is searched, and the city in which the past provision information exists is output as a similar city. The past information provided is searched in the order of the similarity of the target area from the similar city candidates, and if there is no past information provided, the candidate city of the similar city with the next highest similarity is searched. Search for. If there is no similar city that holds the past provision information, information (for example, road congestion information) that belongs to the same information category (for example, road) as the provision information (for example, road traffic availability information) is set as similar information (similar item information). ), A similar city that holds past provision information (similar item provision information) of similar information is extracted. Even if the information belongs to the same information category as the provided information, but the past provided information does not exist, the similar city search unit 1122 outputs data indicating that there is no information (for example, “Null”), and after step S206. Do not execute the processing step.

Here, as the processing in step S205, an example in which the target city is “A city”, the target information category is “road”, and the target disaster is “heavy rain” is shown. First, the similar city search unit 1122 calculates a similar city of City A. The similar city may be selected in advance as a similar city to A city, or may be a neighboring city in the same prefecture as A city, and the information sharing device 1 calculates However, here, an example in which the information sharing apparatus 1 calculates is shown. For example, the city table T126 of FIG. 10 is searched and the similar city of the A city is calculated. A similar city can be selected using the value of the following formula (1). Here, R is the degree of similarity, T _i is the degree of coincidence of the conditions that cause the provided information, and a _i is the weight of the conditions.

R = Σa _i T _i (1)

FIG. 14 is a diagram showing comparison of cities when selecting similar cities. FIG. 14 shows an example in which cities are compared when the weights a _i in the equation (1) are equal.

For example, in the city model table T126 of FIG. 10, the conditions that are the factors of the provided information are city division, population, age-based population composition pattern, topography, main industries, population density, climate, and past events. Depending on the provided information, all the conditions that are factors of the provided information in the city model table T126 may be used, or some of them may be selected and used. Further, the condition weight a _i may be changed for each condition according to the provided information. In the example of the city model table T126 of FIG. 10, each condition in A city to E city is as shown in FIG. In this case, the similar city search unit 1122 outputs B city and E city, whose shapes in FIG. 14 are close to the target city A city, as similar city candidates. Next, the similar city search unit 1122 uses the output candidate city name of the similar city as a key, and using the result table T127 of FIG. 11, the city name is B city or E city, and the cause is heavy rain. A city having a road in the provided information is searched, and as a result, a similar city is specified as the E city.

  In step S206, the result extraction unit 1121 stores, for the similar city output in step S205, one or more past provision information (similar area provision information) that matches the target disaster and matches the target information. Extract from 22. In step S206, the result extraction unit 1121 outputs the storage destination in which the provision information at the time of the target disaster is stored in the data of the similar city by using the result table T127 of FIG. 11, for example, and the information storage unit The past provision information is extracted from 22 using the storage location as a key. In addition, in step S205, when the similar city holding the past provision information of the similar information is extracted, the result extraction unit 1121 extracts the past provision information of the similar information of the similar city. In addition, in step S205, when the similar city holding the past provision information is not extracted, the result extraction unit 1121 regards the information belonging to the same information category as the provision information as the similarity information and the similarity information of the target city. Past provision information (similar item provision information) may be extracted.

  In step S207, the logic comparison unit 1123 uses one or more logics (different) different from the current logic used when the provision information is generated in step S108 and step S109 in the past to provide (provide information Candidates) are generated. In step S207, the logic comparison unit 1123, for example, in step S108 and step S109, the logic of “road with a depth of 5 cm or more is closed” with a logic ID of “L-001” in the information generation logic table T123 of FIG. 7. If the provision information has been generated using, the logic ID other than “L-001”, for example, the logic ID “L-002” “roads with a flood depth of 10 cm or more are closed” in step S207. The road passage permission / prohibition information is generated by using a logic of "road is closed for roads within a radius of 50 m of a landslide disaster location" having a logic ID of "L-003". Here, even if one or more logics different from the current logic is the same as a part of the current logic, the logic as a whole is different (different) from one or more logics. Say that. As a result, a plurality of types of provided information candidates to which logics are applied are generated. In addition, when step S206 is executed, the logic comparison unit 1123 may be one or more different logics and may be one or more logics applied when generating the provision information extracted in step S206.

  In step S208, the logic comparison unit 1123, the provision information generated and provided by the current logic of the target area extracted in step S202, the fact data of the past provision information in the target area extracted in step S203, and step S207. Then, the result of the provision information generated by using another logic in step 3 is output to the information utilization device 4 and the information display unit 115. In step S208, the logic comparison unit 1123, for example, as shown in FIG. 2, the provision information generated and provided by the information sharing apparatus 1 in the past extracted in step S202 (“a road within a radius of 50 m from the earth and sand disaster occurrence location”). Is generated by using the logic of "the road is closed" and "the road with a rainfall of 50 mm or more is closed", the fact data of the provided information extracted in step S203, and another logic in step S207. Information (“Roads with a flood depth of 15 cm or more are closed”, “Roads with a flood depth of 10 cm or more are closed”, “Roads with a flood depth of 5 cm or more are closed”, “Roads within a radius of 100 m of the sediment disaster are closed”, "Roads within a radius of 150m at the site of sediment disasters are closed", "Roads with precipitation of 30mm or more are closed", "Precipitation 10" m or more roads outputs the generated information) using logic, such as suspension of traffic ", the information usage apparatus 4 and the information display unit 115.

  In step S209, the logic comparing unit 1123 accepts an input of a setting change such as a logic change from the user with respect to the result of step S208 and changes the setting, for example, when changing to another logic instead of the current logic ( If S209: YES), the process proceeds to step S210. If the setting is not changed (S209: NO), the logic correction process ends.

  In step S210, the logic changing unit 1124 changes settings such as a method of generating target information. For example, changing the settings means changing the current logic to another logic, adding / changing / deleting provision information corresponding to the type of disaster or business, changing priority, and adding / changing information items that make up provision information. Delete, add or change the generation method, change the priority, add / change / delete the original data that makes up the information item, add or change the combination of the original data, and create the information item (logic or integration process) Including additions, changes, and deletions.

  In step S210, the logic changing unit 1124 adds, changes, or deletes, for example, the information selection table T121 of FIG. 5, the information generation model table T122 of FIG. 6, or the information generation logic table T123 of FIG. To do. When step S210 ends, the logic correction process ends.

  The logic correction process illustrated in FIG. 13 may be performed, for example, for each disaster, or may be performed regularly such as once a week, or when the information sharing apparatus 1 provides new provision information. May be carried out in. Furthermore, the regular implementation and the implementation when a predetermined timing occurs may be combined. Providing the most suitable information according to the situation, such as when new information is provided, when information is updated, when the situation or environment changes, etc. It becomes possible to do.

  In the first embodiment, the case where the provided information is road information has been described. On the other hand, the target of the provided information is not limited to road information, but evacuation site information, hospital information, personal damage information, building damage information, lifeline information (electricity, gas, water supply, communication, etc.), material information Other information, such as, may be used as the provided information. By doing so, other information can be generated and provided from the original data as in the first embodiment. For example, the location information of the shelter and the inundation range information can be integrated, and can be generated and provided as the availability information of the shelter.

  In the first embodiment, the case where only one disaster such as heavy rain occurs as the target disaster has been described. However, the occurrence of multi-hazards such as typhoons coming after the earthquake can occur.

  In this embodiment, information can be provided even when a plurality of target disasters occur. First, if there are a plurality of target disasters, the same information provision process and logic correction process as those in the first embodiment are performed, and if the original data or the actual data cannot be acquired enough to generate information, the target disasters are calculated one by one. The information providing process and the logic correcting process similar to those in the first embodiment are performed for each disaster, and finally the processing results for each disaster are integrated.

  For example, in the information providing process of FIG. 12, step S101 and subsequent steps are first performed by setting the target disaster as a plurality of disasters. If the original data at the time of a plurality of disasters can be sufficiently extracted in step S106, step S107 and subsequent steps are performed as they are. On the other hand, if the original data at the time of a plurality of disasters could not be sufficiently extracted or could not be extracted at all, the process returns to step S101. Then, first, the first disaster is acquired, the processing steps after step S101 are executed for this disaster, and after step S109 is completed, the process returns to step S101 while holding the provision information output by step S109, Next, the second disaster is acquired, and the processing steps after step S101 are executed for this disaster. Similarly, the same processing is executed for each of the third and subsequent disasters, and when step S109 is completed for all target disasters, the provision information generated for all disasters is integrated, and step S110 and subsequent steps are integrated. carry out.

  Further, in the logic correction process of FIG. 13, similar to the process of FIG. 12, the target disaster is set as a plurality of disasters, and step S201 and subsequent steps are executed. If the actual data of multiple disasters cannot be sufficiently extracted in step S203 or step S206, the process returns to step S201, the target disaster is divided into one disaster, and step S201 and the subsequent steps are performed for the first disaster. Actual data is extracted in step S203 or step S206, and information is calculated in step S207. Next, returning to step S201, step S201 and subsequent steps are performed for the second disaster, and steps up to step S207 are performed. After that, extraction of real data and information generation for each of all disasters are repeated, and when the extraction of real data and information generation for all disasters is completed, the information generated by each disaster is combined in step S207 to generate a plurality of data. Generate disaster information.

  In the first embodiment, the disaster information necessary for a disaster has been described as an example. On the other hand, in the present embodiment, it may be used for providing simulation information at the time of urban development, safety judgment of land and buildings, and risk judgment of real estate and insurance based on the safety judgment.

  For example, in urban development, a simulation when a bridge is broken is based on past data that destroyed the bridge in the target city or a similar city, and by constructing a logic, the movement of people or cars after the bridge is broken. Information can also be predicted and provided. Further, by setting the roads to be closed to the bridges to be broken, it is possible to predict and provide the information after the bridges are broken based on the past data of road closures in the target city and similar cities. In addition, in the case of urban development such as road construction and building for attracting large number of customers, it is possible to provide forecast information after urban development based on past data, past data of similar cities, and past data of similar information. it can.

  Further, regarding the safety judgment of the land and the building, one or more hazard maps, cases of past disasters or traffic jams, or information generated by the information sharing device 1 estimated and superposed on the position information of the land or the building. , It is possible to judge the degree of safety of land and buildings. For example, the flood safety level of a rental property, a nursing home, or the like can be calculated by superimposing position information of buildings such as a rental property, a nursery school, or a nursing home on a flood hazard map. Not only floods but also other hazard maps such as tsunamis can be used in the same way for determining the degree of safety, and the same can be done by using past disaster occurrence points and information that the information sharing device 1 has estimated and generated. Can perform processing. Further, not only one but also a plurality of hazard maps and past cases and the positions of the land and the building can be overlapped to determine the degree of safety. The determined safety level can be used as a yardstick for rent of rental properties or nursing homes, disaster countermeasures or crime prevention measures, and can be applied to real estate risk assessment and insurance risk assessment.

  In the first embodiment, the provision information, the actual data, and the calculation result of the information by another logic are output in step S208 of the logic correction processing in FIG. 13, and the user inputs the presence / absence of logic change in step S209.

Then, it is determined whether or not the logic is changed. For example, when the information generated by another logic is closer to the actual data than the information generated by the current logic, the process proceeds to step S210, and the information generated by the current logic is closer to the actual data than the information generated by another logic. For example, the logic correction process may be ended. As a result, the information sharing apparatus 1 presents the logic change proposal, and the information sharing apparatus 1 selects the logic change. Further, the logic change is performed by not accepting the logic change based on the actual data shown in FIG. 13, but by accepting the logic change candidate from the user in step S111 of the information providing process of FIG. You may decide.

  Further, when step S206 is executed, the logic comparison unit 1123, in step S207, calculates the provision information using the logic applied to the generation of the provision information extracted in step S206. In step S209, the process may proceed to step S210 so as to change to this logic.

  In the first embodiment, the information sharing apparatus 1 selects a similar city in step S205 of the logic correction process in FIG. Further, in the first embodiment, FIG. 14 shows the case where the influence degree (weight) of the condition that is a factor of the provided information is constant.
