Description

  The present invention relates to an information distribution system and method for distributing information including an attribute including a literacy type of an information receiver with contents and timing according to the situation of the information receiver.

  In recent years, the occurrence of large-scale natural disasters such as earthquakes, volcanic eruptions, storms and floods, and environmental risks such as food safety issues and chemical health risks have become serious concerns. It has become a concern. In order to respond quickly to human and physical damage such as natural disasters and environmental pollution, and to prevent and reduce damage as much as possible, advance measures such as damage suppression and damage reduction, emergency response, restoration and reconstruction Such ex-post measures are considered important.

  Lifeline that smoothly implements these measures is information communication and emergency in the event of information collection and analysis regarding risks and crises, damage prediction, emergency response and rescue communication, warning and information transmission to residents, confirmation of safety of residents, etc. Moreover, it is said that sharing the same information among the administration, lifeline companies, and disaster victims is the basis for disaster response (for example, see Non-Patent Document 1).

  In addition, in the event of a disaster, there is a limit to how public administration can only help public residents and citizens, so there is a balance that includes self-help to help oneself and mutual assistance to help local residents in line with public assistance. There is a need for effective disaster prevention measures and effective responses during disasters. For this reason, it is necessary to share and provide disaster prevention information not only among various administrative institutions but also between the government and residents, etc. Various kinds of disaster prevention information are available on the Internet when sharing information with residents. Establishing an environment where all citizens can easily access necessary disaster prevention information through the establishment of a disaster prevention information portal site that integrates the contact points of the government and the provision and cooperation of information to the mass media through the disaster prevention information sharing platform (For example, see Non-Patent Documents 2, 3, 4, and 5).

  In self-help, appropriate information to understand what is happening, what is going to happen, what kind of response is appropriate in order to judge, decide and act on what to do It is essential to provide it at the right time. For mutual assistance, information that understands the situation of the region and the work environment is important. Government agencies such as national and local governments need to be aware of the situation of disasters, determine what to do from the information, and take action in order to quickly and appropriately implement responses and countermeasures. . As described above, it is required that the information receiver provides information with contents suitable for the position of the information receiver at an appropriate timing.

  However, at present, accurate prior information does not reach disaster prevention personnel corresponding to this information, and many local governments are delayed or unable to issue evacuation advisories. In addition, in floods and earth and sand disasters, the number of elderly victims is increasing indoors, and information corresponding to information receivers matches information receivers with information receivers such as disaster prevention officers and victims. It is pointed out that it is important to be provided at the same timing (see, for example, Non-Patent Document 1).

  Also, people with various handicaps such as the elderly, disabled, sick, infants, children, resident foreigners, etc. are in a weaker position when a disaster occurs, and the same disaster information as those who do not have a handicap Even if it is provided, there is a problem that it is not possible to respond based on this disaster information.

  In recent years, literacy such as how to read information, how to perceive risk and crisis is different for each individual. For example, in the field of education and human resource development, type classification is based on thinking style, cognitive style, etc., and each type corresponds to type. Methods for providing information are being researched and developed. There are different thinking styles and cognitive styles for individuals to perceive and understand information. For example, the axis of whether things are considered analytically or wholly, There are two orthogonal axes of whether things are handled verbally or imager, and can be classified into roughly four types, or analytical, logical, It is classified into four types, such as rational viewpoint, intuitive, conceptual, and overall viewpoint, detailed time-series viewpoint, emotional viewpoint, etc., and is going to be used for education and human resource development (for example, non-patent References 6 and 7).

The distribution rule 1002 is stored in the information distribution rule management unit 606. Further, in the example of FIG. 10, each of the information receivers a, b, and c is changed to the information targets T1, T2, and T3 by the target determination unit 610 and the literacy type determination unit 611, and the literacy type is RT1, RT2 and RT3 are determined (1001). The information filtering unit 612 selects the disaster prevention information having the information content corresponding to each information receiver and having the information attribute by applying the determination result 1001 to the information distribution rule. For example, since it is determined that the information target is T1 and the literacy type is RT1, the information receiver a includes the information content IC1 to be distributed to the information target T1 and is easily understandable for the literacy type RT1. Information 1 having is selected. Then, the information distribution unit 613 distributes the selected information to the information receiver 1. Similarly, information receiver b selects information content IC2 and information 2 having information attribute IA2, and information receiver c selects information content IC3 and information 3 having information attribute IA3. And delivered.

Next, an example of the role of the information receiver, which is a factor of the information target that defines the information content, will be described with reference to FIG.
As information receivers, for example, there are various disaster prevention organizations such as national and local governments and disaster prevention personnel who are responsible for implementing disaster prevention and mitigation measures. In addition to supporting the response and countermeasures implemented by various disaster prevention organizations such as the national and local governments, and in some cases, supporting businesses such as lifeline companies, hospitals, etc. There is a logistical support organization. Furthermore, there are disaster victims who evacuate themselves and assist those who need assistance. For each role and situation, there is information content necessary for information receivers to understand the situation, recognize the possibility of a disaster, and take action. The information processing unit 615 refers to the information design rule, and processes the information according to the information configuration and information generation procedure for generating the information of the content corresponding to the information receiver.

Next, an example of the classification of the victim who is a factor of the information target that defines the information content will be described with reference to FIG.
When the information receiver is a disaster victim, it is necessary to define the contents of information to be distributed corresponding to various attributes of the disaster victim. For example, as shown in FIG. 12, the victim is a resident or non-resident, whether the resident is a local inhabitant of the information to be received, or who happens to be present (non-resident), and the information receiver For example, there is a difference between whether or not some kind of assistance is required when taking action such as evacuation in response to a disaster, and as a person requiring assistance, a disabled person, an elderly person, a guardian with an infant, an infant, It is classified according to differences in people who have difficulty understanding Japanese, etc., and there is information corresponding to each.

  On the other hand, the provision of information provided to disaster prevention agencies, disaster prevention personnel, logistic support, etc. is basically stipulated in the disaster prevention manual etc. which information element is used to create which information and to whom information is distributed. For example, if the detailed duties are known, the information to be distributed is uniquely determined.

Next, an example of regional characteristics that are factors of information that defines the information content will be described with reference to FIG.
Since natural disasters are highly dependent on the topography, geology, and weather conditions that depend on topography, the situation, prediction, and response of disasters vary depending on regional characteristics. For example, it is necessary to create and distribute disaster prevention information etc. corresponding to the characteristics of the area where the information receiver is located, such as areas with heavy snowfall, peninsulas, mountainous areas, etc. where public transportation is limited is there. The information processing unit 615 refers to the information design rules and processes the information in accordance with the information configuration and information generation procedure for generating disaster prevention information having information contents corresponding to these regional characteristics. As described above, this regional characteristic is included in the receiver attribute.

  The object determination unit 610 determines the role of the information receiver and the classification of the victim. For example, the personal identification code that identifies the information recipient, the role when using this identification code, the attributes such as the classification of the victim, etc. are registered in advance, and when the information recipient accesses the system, It can be determined by inputting a personal identification code. In addition, when an information receiver accesses the system, an attribute list of roles that are classified and registered in advance and classification as a victim is displayed, and items corresponding to the information receiver from among them are displayed. May be selected by the information recipient.

  When the information receiver accesses the area characteristic to receive information, the object determination unit 610 selects the code of a desired area from the list of area identification codes registered in advance, for example. It is possible to adopt a configuration to be selected. Also, a personal identification code for identifying the information receiver and a regional attribute when this identification code is used are registered in advance, and the personal identification code is input when the information receiver accesses the system. Therefore, a configuration may be adopted in which the determination is performed by the target determination function. Furthermore, when accessing information from a terminal (not shown) or the like that can specify a region such as GPS, information on this specified region is obtained from the terminal or the like with this system, and disaster prevention information corresponding to this region is distributed. May be.

Next, an example of the type of literacy that is a requirement for disaster prevention information will be described with reference to FIG.
Distribution of risk information, crisis information, etc. is intended for information recipients to immediately read the information, understand the contents, make decisions, and act. Understand the situation accurately and promptly, provide information on the attributes that are most necessary to judge, make decisions and act on risks and crisis. Individual literacy includes, for example, personal information contact ability, information understanding ability such as how to view and understand information itself, understanding method, risk and crisis judgment ability, situation judgment ability, information-based decision-making ability, Furthermore, there is a behavioral ability.

The various literacy determinations shown in FIG. 14 are based on the literacy type determination map composed of a plurality of axes corresponding to the main constituent factors for determining the internal attribute of the information receiver regarding the literacy. A method for determining an attribute is used.
Next, a basic configuration of the literacy type determination unit 611 will be described with reference to FIG.
The literacy type determination unit 611 includes an internal attribute determination unit 1501 and a literacy type determination map 1502. The internal attribute determination unit 1501 includes a question group management unit 1503, a mapping unit 1504, an attribute value analysis unit 1505, and an attribute assignment unit 1506. The literacy type determination unit 611 maps a point corresponding to the information receiver on the literacy type determination map 1502 and determines an internal attribute type of the information receiver corresponding to the position of the arranged point.

  The literacy type determination map 1502 represents a multi-dimensional space centered on factors of internal attributes related to sensitivity, such as how to read target information, how to grasp risks and crisis, and internal attributes related to personal sensitivity. It consists of a group (cluster) having characteristic internal attributes, and has a function as an index for determining the internal attributes of individual information receivers. The axes of the multidimensional space are indexed so that the position where the point corresponding to the internal attribute of each information receiver is placed can be quantitatively evaluated in order to quantitatively determine the internal attribute of the information receiver. ing. There are many clusters with various typical internal attributes in a multidimensional space with internal attributes as axes, and information is received using the default value corresponding to each axis of the cluster boundary as an index. The inner attribute of the person is determined. Each cluster basically does not have an overlapping portion independently, but a plurality of clusters can overlap depending on the field and type of information handled by the literacy type determination unit 611. In FIG. 15, for the sake of simplicity, the axes are shown as A, B, C, and the characteristic attribute types of clusters characterized by combinations of axes are 1 to 8, but the information provided It is also possible to change the number of axes and the attribute type depending on the point of view, such as how to read, how to understand risk and crisis.

  The question group management unit 1503 stores a question group in which items as main constituent factors necessary for determining the internal attribute type of each individual information receiver are set as question items. Each question item is designed so that the internal attribute determination unit 1501 can clearly characterize the internal attributes regarding how to read the information targeted by the information recipient, how to understand the risk and crisis, etc. ing.

  The mapping unit 1504 places points corresponding to individual information receivers on the literacy type determination map 1502. Based on the numerical data obtained by the attribute value analysis unit 1505, the mapping unit 1504 determines the position of a point in the literacy type determination map 1502 to which the attribute of the information receiver corresponds.

  The attribute value analysis unit 1505 quantitatively analyzes the arrangement position with respect to each axis in the literacy type determination map 1502 of each information receiver. The attribute value analysis unit 1505 uses, as an original data, the information receiver's response to the question group, which is input by an internal attribute information input function (not shown) of the question group management unit 1503. The numerical data indicating the position of each axis of the literacy type determination map is quantitatively analyzed by the analysis method described above.

  The attribute assigning unit 1506 assigns a characteristic attribute type by specifying a cluster to which the information receiver belongs. The attribute assignment unit 1506 identifies the type of the cluster to which the position corresponding to the information receiver belongs by the mapping unit 1504 as the type to which the information receiver belongs. This identification makes it possible to objectively and quantitatively understand the internal attributes regarding how to read and grasp the risk information of the information receiver.

  In general, a known analysis method such as multivariate analysis such as principal component analysis or cluster analysis is employed for analysis and classification of internal attributes related to human sensitivity. For example, the internal attribute of an individual is digitized based on the principal component score obtained by principal component analysis, the position to be placed in the literacy type determination map is determined based on the numeric value, and the cluster using each principal component score You may employ | adopt the method of classifying automatically by analysis. At this time, the distance between the input position in the factor coordinate space corresponding to each individual analysis axis and the center coordinate position of each cluster is calculated, and it is determined that it belongs to the type of the cluster with the shortest distance. Specifically, for each analysis axis, the information receiver answers multiple questions that analyze where the axis is located, and based on the response results, principal component analysis is performed. Derive component scores. Subsequently, the position of the individual in the information recognition map is determined, and a cluster belonging to the specified cluster is determined. The determination method is, for example, specified to belong to the cluster closest to the specified cluster center, and is determined. These principal component analysis and cluster analysis can be performed with a statistical analysis tool such as SPSS. Further, the calculation of the principal component score and the cluster determination belonging thereto may be performed using an approximate expression calculated in advance.

Next, an example of a question group for determining the literacy type stored in the question group management unit 1503 will be described with reference to FIG.
For each question item, select the most appropriate answer from the five levels of “not so”, “neither”, and “yes”, and perform the principal component analysis on the results to make the inner Digitize attributes.

An example of the internal attribute regarding risk information recognition classified by this method is shown in FIG.
Type 1 is highly dependent on third parties for literacy and judgment and has a certain degree of information literacy, but has an internal attribute that is easily influenced by the tone of the information source. Type 2 has a low risk zero orientation and low third party dependency, and has an internal attribute that understands risk while collecting and judging information by itself. Type 3 has a low level of information literacy and disaster prevention knowledge, is not good at difficult information, and has internal attributes that are easily influenced by people. Type 4 is high in both information literacy and risk zero orientation, is sensitive to risk, and information has an internal attribute to be confirmed and judged by itself.

Next, an example of the correspondence between the internal attribute (type) and the basic information attributes that the risk information to be provided and the crisis information should have will be described with reference to FIG.
For type 1 information recipients, a summary summarizing points rather than detailed information and information with a configuration that concludes with a single word are suitable. For type 2 information recipients, accurate and specialized information is appropriate. For information recipients of type 3, information of a structure that summarizes the points and explains them in the order of the muscles rather than detailed information, and shows the way of viewing, points of interest, etc. is suitable for the chart. For information recipients of type 4, information with a structure that is presented as it is and explained in detail using a chart is suitable.
For example, these types can be associated with the information configuration shown in FIG. The configuration example 1 in FIG. 9 is shown in a lump so that each summary can be listed, and each detailed information is arranged in a lower layer of each summary. Therefore, the configuration corresponding to type 1 and type 3 It is. The configuration example 2 in FIG. 9 has a configuration in which the outline and details are arranged in a lump in order, and is a configuration corresponding to the type 4 that does not need to be read unless all information is read. In configuration example 3, only the title is shown first, and since it is configured to show “summary” and “details” of each information in the lower layer, the entire configuration is grasped, and information necessary at random It is the structure corresponding to the type 2 which reads only.

Next, an example of providing information at a timing according to the situation performed by the timing determination unit 609 and the information distribution unit 613 will be described with reference to FIGS. 19A and 19B.
The purpose of providing risk information such as disaster prevention information and crisis information to information receivers is to make the information receivers understand the situation as a party, recognize the possibility of disaster occurrence, and take action to make the disaster occur. It is to prevent and minimize damage. For this reason, as shown in FIG. 19 (A), in accordance with the situation where the information receiver is placed and the progress of the situation, Information 1A to understand, information 2A for information recipients to recognize the possibility of disaster occurrence, information 2A for decision making, and information 3A for information receivers to take action in situation 3 at the timing corresponding to the situation is doing.

  For example, as shown in FIG. 19B, the level of the situation in which the disaster prevention information is provided in advance as the situation progresses is provided, and the relevant information is provided when the situation reaches the relevant level. In the example of FIGS. 19A and 19B, information 1A is received when the situation reaches level 1A, information 2A is received when level 2A is reached, and information 3A is received when level 3A is reached. To each person A. Further, for example, when the information receiver B is a person requiring assistance who needs time for evacuation preparation or the like, as shown in FIG. 19B, the level of the situation for determining the timing of information distribution is 1B, 2B, 3B Accordingly, the timing of distributing information is accelerated to timings 1B, 2B, and 3B, respectively, and the contents of information to be provided are also different.

Next, an example of the relationship between the criteria for determining the timing for distributing information, the classification of information recipients when the level of the situation has reached this criterion, and the information content to be distributed will be described with reference to FIG.
When the level of the situation reaches level 1B, information of information content 1B is distributed to information receivers corresponding to category B. When the situation progresses and the level reaches level 1A, information of information content 1A is distributed to information recipients corresponding to category A. Here, the classification of the information receiver corresponds to the inhabitants, non-residents, supporters, and persons requiring assistance shown in FIG. As shown in FIG. 20, the situation level and the information recipient who distributes the information are classified as a victim, and the information content is determined in advance, so that the timing according to the information recipient is determined by the situation level monitor or the like. Thus, it is possible to distribute information such as contents corresponding to the information receiver to the corresponding information receiver.

Next, as an example of the situation, a situation from the viewpoint of the evacuation behavior of the information receiver will be described with reference to FIG. Further, the situation from the viewpoint of the time series of the occurrence of the situation will be described with reference to FIG.
In FIG. 21, the stage of grasping the situation, the stage of evacuation preparation, the stage of evacuation decision, the stage of starting action, etc. are assumed. In FIG. 22, stages such as immediately before the occurrence of the situation, when the situation occurs, immediately after the occurrence of the situation are assumed. In the present embodiment, the information distribution unit 613 distributes information corresponding to the information receiver at a timing for prompting a countermeasure corresponding to the information receiver according to these situations.

  The information receiver inputs various information necessary for determining the information target, literacy type, and the like to the determination unit 604, so that the risk information and crisis information of the content corresponding to the information receiver's information target, literacy type, etc. The information distribution unit 613 distributes disaster prevention information such as the above. Further, based on the determination result of the current situation by the timing judgment unit 609, the information delivery rule management unit 606 delivers the disaster prevention information at a timing that matches the situation of the information receiver.

  The timing of providing information to the information receiver is in charge of damage forecasts by disaster information and simulation, weather forecasts by weather conditions and simulations, earthquake forecasts by earthquake conditions and simulations, disaster prevention agencies, disaster prevention personnel, and logistic support Based on information such as relief information and future schedules implemented by cooperating companies and hospitals, and other various information and schedules such as simulations, forecasts, etc., and information on the status of information receivers themselves Is determined by the timing determination unit 609. The timing determination unit 609 determines, as the information distribution timing, a point in time when a predetermined reference value is reached based on observation data such as river water levels and precipitation in mountainous areas, for example. In addition, the timing determination unit 609 determines, as the information distribution timing, a time point at which a predetermined reference value is assumed based on a prediction value obtained by simulation using observation data. Furthermore, as shown in FIG. 19B, depending on the degree of urgency, the timing determination is triggered by reaching a predetermined level of progress of the situation based on the situation determination result by the person in charge of disaster prevention, etc. The unit 609 determines the timing of information distribution. Information serving as a basis for determining the situation may be accumulated in the disaster prevention information sharing DB included in the information sharing unit 601 in FIG. In addition, information delivery timing information may be directly input to the timing determination unit 609 in real time from a disaster prevention agency or a person in charge of disaster prevention.

Next, an example of a template of an information design rule when the person in charge of disaster prevention and the disaster prevention organization are information receivers will be described with reference to FIG. FIG. 23 corresponds to the object 1 in FIG.
The template of the information design rule includes common information elements that can constitute the information corresponding to the current situation, future predictions, necessary responses, etc. that constitute the disaster prevention information, and individual disaster prevention organizations. Each of the information elements constituting the information is described. In addition, information necessary for each person in charge differs in the disaster prevention organization, and therefore, information elements that can constitute necessary information for each person in charge are shown in a hierarchical manner. Furthermore, when it is necessary to add essential contents or the like to the regional characteristics, information elements that can constitute the regional characteristics and information necessary for the characteristics are also described.
For example, “Information element A-1, Information element A-2...” Described in the column “Current situation”-“Common item” in FIG. 23 is “Current state” when the disaster prevention agency is an information receiver. "Information element A-1, information element A-2 ..." is determined to be a necessary information element. That is, if there is any information element of information element A-1, information element A-2... Among the plurality of information elements acquired from the information sharing unit 601, the information extraction unit 614 selects the information element. Extracted as information to be included in "current situation"-"common items".
Furthermore, it is described in each column of FIG. 23, for example, a column of “future forecast”-“individual item organization 1” (information element B-3, information element B-4... Are described). When the information element is stored in the information sharing unit 601, the information extracting unit 614 extracts the information element in the corresponding field.
Thereafter, the extraction process in the information extraction unit 614 ends, and the extraction result passed to the information processing unit 615 includes, for example, one or more information elements in each column of FIG. If there is no corresponding information element in the information sharing unit 601 in the column of FIG. 23, this column is blank. When the information distribution unit 613 distributes risk / crisis information having a blank, when the information corresponding to the blank is presented, for example, “no information” is displayed.
Although FIG. 23 demonstrated the case where disaster prevention organization was made into the object, the case of logistic support etc. is the same.

Next, an example of an information design rule template when the disaster victim is an information receiver will be described with reference to FIG. FIG. 24 corresponds to the object 1 in FIG.
Since victims are required to evacuate according to the situation, the contents of information transmitted to all victims are basically the same. However, if individual information elements are required due to the classification of the information recipients shown in FIG. 12, the risk / crisis information includes the current situation that constitutes disaster prevention information, future predictions, Common information elements constituting the information and information elements constituting the individual information for each victim are described. Furthermore, corresponding to the regional characteristics shown in FIG. 13, information elements constituting information necessary for the regional characteristics are also described. The meaning of each column is the same as in the example of FIG. The information elements described in each column can vary depending on the information recipient.

  In general, the contents of disaster prevention information are stipulated in the disaster prevention manual as described above. Further, the information attribute corresponding to the literacy type of the information receiver is known by a known analysis method such as multivariate analysis such as principal component analysis or cluster analysis as described above. Therefore, creation of disaster prevention information based on information elements, provision of information attributes, etc. can be carried out using technologies such as templates used in information creation, tags such as XML, metadata, etc. . For example, the information extraction unit 614 refers to the information design rule, selects and uses a necessary template from among a plurality of templates or templates defined in the rule, and acquires the template from the information sharing unit 601. Information is extracted by mechanically flowing information elements into the selected template or template. Furthermore, a template for processing for each of a plurality of literacy types is prepared for the information processing unit 615 in the information design rule management unit 608, and the information processing unit 615 embeds information elements to be specified in this template. The processing performed by the information assembling unit 801, the information converting unit 802, the information processing unit 803, the information hierarchizing unit 804, and the information configuration rearranging unit 805 may be completed. In addition, the information filtering unit 612 can select information corresponding to the information recipient, mask, and the like using a tag, metadata, and the like.

Next, operations of the information extraction unit 614, the information processing unit 615, and the information storage unit 607 will be described with reference to FIG.
The information sharing unit 601 detects that a new information element has been input to the information sharing unit 601 (step S2501). Information extraction unit 614 and information processing unit 615 use this detection as a trigger to refer to information design rules for creating and processing disaster prevention information using this new information element (step S2502), and target necessary information And an information unit having an information attribute corresponding to the literacy type of the information receiver is created and processed (step S2503). Furthermore, using this information unit, the information processing unit 615 creates and processes information having contents corresponding to the necessary information target and information attributes corresponding to the literacy type of the information receiver (step S2504). ) And is stored in the information storage unit 607 (step S2505).

Next, an outline of a basic information distribution flow performed by the timing determination unit 609, the target determination unit 610, the literacy type determination unit 611, the information filtering unit 612, and the information distribution unit 613 will be described with reference to FIG.
The information filtering unit 612 uses the detection that the new information is stored in the information storage unit 607 as a trigger (step S2601), refers to the information distribution rule (step S2602), and performs necessary information filtering processing (step S2603). . The information distribution unit 613 distributes necessary information to the information receiver (step S2605) according to the information distribution rule and according to the timing determination result of the timing determination unit 609 (step S2604).
In the example of FIG. 26, the information delivery to the information recipient is a push type delivery of information to the information recipient with the creation of new information as a trigger. Access from the information receiver may be performed even during normal times. By registering information targets, literacy types, and the like at the time of normal access, information is distributed in a push type when necessary. In addition, when information distribution is continuously performed, if the information target of the information receiver changes, the information is accessed by registering the information target accessed by the information receiver. It is possible to change the information to information having contents corresponding to the object of the information.

An example of a basic information providing flow will be described with reference to FIG.
The information receiver inputs role determination information to the information distribution system of this embodiment (step S2701). The information receiver selects a corresponding item from, for example, various disaster prevention organizations, disaster prevention officers, cooperative operators, logistic support organizations, and victims. The object determination unit 610 determines the role of the information receiver (step S2702). If it is determined in step S2702 that the person is not a disaster victim, the object determination unit 610 identifies the information object from the role of the information receiver (step S2703), and the corresponding information is distributed according to the information distribution flow shown in FIG. S2704).

  When it is determined to be a disaster victim in the role determination in step S2702, in the case where the target determination unit 610 is a resident or a resident, a supporter or a supporter, or a supporter, protection with a disabled person, an elderly person, or an infant A detailed role is selected from a person, an infant, a person with difficulty in speech, and others (step S2705) (refer to the description of FIG. 13 for details), and an object of information corresponding to the role is specified (step S2705). S2706). Subsequently, an answer to the question group necessary for the internal attribute determination is obtained from the information receiver by the internal attribute information input function of the question group management unit 1503 (step S2707). The question group to be presented is presented to the information receiver by the question group management unit 1503. The answers to the question group input by the information receiver are transferred to the attribute value analysis unit 1505. In order to quantitatively determine the internal attribute of the information receiver, the attribute value analysis unit 1505 quantitatively analyzes the arrangement position with respect to each axis in the literacy type determination map using the obtained answer as the original data (step S2708). ), Mapping section 1504 individually arranges points corresponding to the information receiver on literacy type determination map 1502 (step S2709), and attribute allocation section 1506 determines the cluster to which the corresponding position of the information receiver belongs (step S2709). S2710). Subsequently, with reference to the attribute correspondence table (FIG. 18) by the attribute assignment unit 1506, the literacy type determination unit 611 extracts information attributes corresponding to the cluster type (step S2711), and the information distribution flow shown in FIG. The information content corresponding to the information object specified in accordance with the information attribute information corresponding to the specified literacy type is distributed (step S2712).

  Information receivers such as disaster prevention information can be assumed to access disaster prevention information in various environments such as indoors, outdoors, areas where public networks are available, and areas where public networks are unavailable. For this reason, the information distribution unit has a function of determining an information terminal or the like that has been accessed by the information receiver and distributing disaster prevention information in a format corresponding to the information terminal.

  Each unit is basically mounted on a computer (server, personal computer) or the like, and each function is connected via an information communication network, distributes necessary disaster prevention information, and provides disaster prevention information. The information communication network is constructed by a public network, a dedicated line, an IP network, a LAN, a WAN, a private network, and the like.

  According to the embodiment described above, the information receiver's information is read in the content corresponding to the role of the information receiver, the situation at the time of information distribution, the region covered in the information distributed to the information receiver, Distribute information such as risk information, crisis information, etc. that have information attributes such as composition, expression format, etc. to information receivers at a timing corresponding to the progress of the situation. Therefore, it is possible for the information receiver to understand the situation as a party, to recognize the possibility of a disaster, and to take action, thereby preventing the occurrence of a disaster and minimizing damage.
