  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  Referring to FIG. 1, an information storage and provision apparatus according to an embodiment of the present invention operates under program control, and includes a user request input unit 101, a selection criterion generation unit 102, a disaster information selection unit 103, a disaster The information output unit 104, the user information input unit 105, the user information storage unit 106, the disaster information input unit 107, the disaster attribute information generation unit 108, and the disaster information storage unit 109 are configured. Further, since it is well known to those skilled in the art and is not directly related to the present invention, detailed description of the configuration is omitted, but a control unit (not shown) controls each functional unit.

  The information storage and provision apparatus of the present invention is characterized in that useful information can be efficiently presented to a user from among a large amount of stored information. For this purpose, information about the user is stored in advance. And good. First, the user information input unit 105 and the user information storage unit 106 that are provided for storing information about the user in advance will be described.

  In the user information input unit 105, the user inputs his / her user information and outputs it to the user information storage unit 106. This corresponds to an operation in which the user performs user registration with the information storage and provision apparatus. The user inputs at least one item from among, for example, “name”, “region”, “mail address”, and “profession” as his / her user information. As will be described later, the user information input here is used when the user tries to receive the disaster information from the information storage / providing device of the present invention, or when the user stores the disaster information of the present invention. Used when providing to a providing device.

  The user information storage unit 106 stores user information input from the user information input unit 105. The accumulated user information is output to the selection criterion generation unit 102, the disaster information selection unit 103, and the disaster attribute information generation unit 108 as necessary and used.

  As described above, the information storage and provision apparatus of the present invention is characterized in that useful information can be efficiently presented to a user from among a large amount of stored information. A mechanism for accumulating is needed. Therefore, the disaster information input unit 107, the attribute information generation unit 108, and the disaster information storage unit 109 that are provided for storing information related to disasters and the like will be described.

  The disaster information input unit 107 inputs disaster information and outputs it to the disaster attribute information generation unit 108 and the disaster information storage unit 109. Disaster information can be transmitted from local governments, local government officials, police, fire departments, fire brigades, mass media, residents, and the like. Disaster information is generally composed of at least one of text, still images, and moving images. Information about disasters that occurred, information about damage, information necessary for evacuation life, materials and information needed by disaster victims Information about support, etc. that volunteers can provide. The disaster information includes unconfirmed information whose accuracy of transmission by residents is unknown in addition to high-accuracy confirmed information transmitted by local governments.

  The disaster attribute information generation unit 108 generates disaster attribute information to be added to the disaster information input by the disaster information input unit 107 and outputs the disaster attribute information to the disaster information storage unit 109. As disaster attribute information, time information, regional information, input person information, reliability information, information indicating a major classification (category) of contents, contents of the disaster information input by the disaster information input unit 107 There is information indicating the degree of urgency. At least one of these pieces of information is output to the disaster information storage unit 109 as disaster attribute information. Here, when the information of the input person and the reliability information are used as the disaster attribute information, the user information stored in the user information storage unit 106 may be searched and used. Specifically, the “name” and “occupation” items included in the user information may be used as input information, or reliability information may be generated from “occupation”.

  The disaster information accumulation unit 109 accumulates the disaster information input from the disaster information input unit 107 and the disaster attribute information which is information accompanying the disaster information and input from the disaster attribute information generation unit 108 as disaster information with attributes. To do. The accumulated disaster information with attributes is output to the disaster information selection unit 103 as needed and used. Here, when disaster information is accumulated, disaster information including inappropriate words or disaster information entered by a person who has been registered in advance for reasons such as having entered inappropriate information in the past. You may filter disaster information. As a specific means of filtering, the information is not accumulated in the disaster information accumulation unit 109 or the content of the disaster information is inquired to a person who manages the disaster information accumulation / providing device of the present invention, and the disaster information accumulation unit 109 For example, it is determined whether or not it can be stored. As a result, it is possible to prevent the accumulation of inappropriate disaster information such as ryuugo.

  As described above, the information storage and provision apparatus according to the present invention is characterized in that it can efficiently present useful information to the user from a large amount of attributed disaster information stored in the disaster information storage unit 109. Therefore, it is necessary to determine whether each disaster information is useful for each user and to provide the disaster information in order of importance to each user according to the result. The user request input unit 101, the selection criteria generation unit 102, the disaster information selection unit 103, and the disaster information output unit 104 that are provided to realize this mechanism will be described.

  In the user request input unit 101, the user inputs user request information and outputs it to the selection criterion generation unit 102. This user request information is used as information for determining the importance of the disaster information to the user in the selection criterion generation unit 102 described later. Examples of user request information include "time", "region", "emergency", "category", "user attribute", "reliability", "unspecified (automatic)", "specific disaster information ". The user selects at least one item from the above-described examples of user request information from a terminal (PC, mobile phone, etc.) being used. Which item is selected is output to the selection criterion generation unit 102 as user request information. Here, when a plurality of items are specified from the above-described example of the user request information, the user inputs the relative priority among the plurality of items by numerical values and ranks, It may be included in the user request information. In addition, when items “region”, “category”, “user attribute”, and “specific disaster information” are selected as the user request information, “important region”, “important category” It is preferable to add “important user attributes” and “identifiers indicating specific disaster information” to the user request information. Thereby, a specific area, a specific category, a specific user attribute, and a specific disaster information can be preferentially presented to the user.

  The selection criterion generation unit 102 generates selection criterion information using the user request information input from the user request input unit 101 and the user information of the user who has input the user request information, and provides disaster information. The data is output to the selection unit 103. The selection criterion information is information indicating which items are to be regarded as important among the items of the disaster attribute information included in the disaster information with attributes stored in the disaster information storage unit 109. Specifically, for each item of disaster attribute information, there is a method of quantifying the degree of emphasis on the item with a real number from 0 to 1.

For example, it is assumed that disaster information including disaster attribute information shown in FIG. The selection criterion information is composed of six sets of real numbers S (1 to 6) from 0 to 1.0,
S (1) = degree of importance of “time information” S (2) = degree of importance of “geographic information” S (3) = degree of importance of “emergency information” S (4) = “category information” Assume that the degree of importance S (5) = the degree of importance of “user attributes” S (6) = the degree of importance of “reliability information”. In other words, when the item “time” is selected as the user request information,
S (1-6) = {1.0, 0, 0, 0, 0, 0}
It becomes. This means that only the time information is emphasized in the disaster attribute information shown in FIG.

In addition, if the item “Geography” is selected as user request information,
S (1-6) = {0, 1.0, 0, 0, 0, 0}
It becomes. In addition, when it is specified that “time information” has the first priority and “geographic information” has the second priority as the user request information,
S (1-6) = {1.0, 0.5, 0, 0, 0, 0}
And so on. Here, S (1) as the first priority is set to 1.0 and S (2) as the second priority is set to 0.5. However, if S (1) is larger than S (2), Other values may be used.

When “Non-designated” is selected as the user request information, S (1-6) is a constant,
S (1-6) = {0.8, 1.0, 0.5, 0, 0, 0}
It is good to set with a constant like this. In this case, the constant may be changed according to the user information of the user who has input the user request information. For example, if the user is a “local government employee,” it can be assumed that the importance of information that the local government or neighboring local government is a sender is high.
S (1-6) = {0.3, 1.0, 0.3, 0, 1.0, 0}
It is possible to realize information presentation that emphasizes geographic information and user attributes.

In addition, if the user is a “resident” outside the disaster area, the importance of geographic information is low, and it can be assumed that the importance of assistance request information sent by the disaster area residents is high.
S (1-6) = {0.3, 0, 0.3, 1. 0, 0.7, 0}
And so on.

  The disaster information selection unit 103 determines the importance of each attributed disaster information stored in the disaster information storage unit 109 while referring to the selection criterion information, and outputs the attributed disaster information in descending order of importance. Output to the unit 104.

  As an example of the determination method of the importance level, the first importance level is determined for each item of the disaster attribute information, and the weighting for each item included in the selection criterion information is performed with respect to the first importance level for each item. There is a method in which weighting is performed by multiplying by a coefficient, and the importance is calculated by cumulatively adding the first importance for each item subjected to the weighting for each disaster information with attributes.

  For example, it is assumed that disaster information including disaster attribute information shown in FIG. Here, the importance corresponding to the record number R (R = 1 to 5) in FIG. 2 is assumed to be T (R). When the selection criterion information is S (1-6) described above, the importance T (R) may be calculated by the following procedure as an example.

  If S (1) is not 0, for each record R (R = 1 to 5), the score A (1, R) is from 0 to 1 so that the time information of the disaster attribute information increases in order from the newest. Set as a real number of .0 (step 1).

  If S (2) is not 0, for each record R (R = 1 to 5), the score A (2, R) is the geographic area of the disaster attribute information is the “important area” of the user request information. Are set as real numbers from 0 to 1.0 so that the values increase in the order close to (step 2).

  If S (3) is not 0, for each record R (R = 1 to 5), the score A (3, R) is increased from 0 to 1 so that the value increases in descending order of the urgency of the disaster attribute information. Set as a real number of .0 (step 3).

  If S (4) is not 0, for each record R (R = 1 to 5), the score A (4, R) is the category information of the disaster attribute information is the “important category” of the user request information. If it matches, a large value (for example, 1.0) is set, and if not, 0 is set (step 4).

  If S (5) is not 0, for each record R (R = 1 to 5), the score A (5, R) is used by the user attribute of the disaster attribute information as “important use” of the user request information. If it matches the “person attribute”, a large value (for example, 1.0) is set, and if not, 0 is set (step 5).

  If S (6) is not 0, for each record R (R = 1 to 5), the score A (6, R) is 0 to 1 so that the value increases in descending order of the reliability of the disaster attribute information. Set as a real number of .0 (step 6).

  The importance T (R) of each record R (R = 1 to 5) is set to A (1, R) × S (1) + A (2, R) × S (2) + A (3, R) × S ( 3) + A (4, R) × S (4) + A (5, R) × S (5) + A (6, R) × S (6) (step 7).

  In the following, FIG. 2 is used to specifically show in what order the disaster information selection unit 103 outputs attributed disaster information.

  When the item “time” is selected as the user request information, S (1-6) = {1.0, 0, 0, 0, 0, 0}, and record numbers 1, 2, 3, 4 Disaster information with attributes is output in the order of 5.

  When the item “geography” is selected as the user request information, S (1 to 6) = {0, 1.0, 0, 0, 0, 0}, and “region to be regarded as important” is “ If it is “A city AA town”, the disaster information with attributes is output in the order of record numbers 1, 2, 5, 3, and 4. Here, since the record numbers 2 and 5 or the record numbers 2 and 3 are the same geographical information, the order may be reversed. Here, it is assumed that A city is closer to A city than A city is AB city than B city is BA city.

  When the user request information is specified as “time information” having first priority and “geographic information” having second priority, S (1-6) = {1.0, 0.5, 0 , 0, 0, 0}. As described above, when only the item “time” is selected as the user request information, the importance increases in the order of record numbers 1, 2, 3, 4, and 5. Since “Geographic information” is selected, if the “area to be important” in the user request information is, for example, A city AB town, the importance of records 2 and 5 becomes higher, and attributed disasters The order in which information is output may change. Here, whether or not the order changes depends on what real numbers A (1, R) and A (2, R) are used for each of the above-described records R (R = 1 to 5). To do.

  The disaster information output unit 104 presents attributed disaster information output in descending order of importance by the disaster information selection unit 103 on the user's PC screen, mobile phone screen, or the like. Here, the higher the importance, the more information from the disaster information with attributes is presented to the user, and the less important the information about the disaster information with attributes such as the title, summary, and information on the full text acquisition means. Part may be output. For example, about 3 to 5 pieces of information in descending order of importance, the disaster information full text is presented to the user, and for the subsequent information, title information and information for knowing the disaster information full text (URL etc.) Is displayed as information of about one line. As a result, a large amount of information can be listed, and particularly important information can be conveyed to the user in detail and with certainty.

  Here, an apparatus and a method that can efficiently present useful information for users out of a large amount of information for disaster information have been described. However, even if it is information other than disaster information, this information storage and provision device, this information can be used as long as it has attribute information items and can determine the overall importance by weighting the importance for each item. By using the storage providing method and the information storage providing program, useful information can be efficiently presented to the user.

It is a block diagram which shows the structure of embodiment of this invention. It is an example of the disaster information in embodiment of this invention. It is a block diagram which shows the conventional information storage provision apparatus.
