[System overview]
An example of an embodiment of the present invention is an application provided by a management company that manages real estate such as condominiums. The management company generally dispatches a condominium manager to the real estate and manages it for a predetermined time on a working day. However, since it is not practical to perform 24-hour management work, the concierge service is provided using the application of the present invention. The server device 1 may be managed by a management company. The server device 1 may be prepared for each real estate property to be managed.

[Information search processing]
Next, the information search process of the information search system 4 will be described. FIG. 3 is a flowchart regarding the information search processing, which corresponds to at least one of the embodiments of the present invention.

First, the terminal device 3 receives the input of the inquiry content by the user (step S1). The user's input may be, for example, input of text data by a touch operation on a touch panel included in the terminal device 3, or the user may speak into a microphone included in the terminal device 3 so that the terminal device 3 outputs voice data. It may be converted into text data. Further, the content analyzed by the code or the like included in the captured image may be input by the image capturing function of the terminal device 3. The inquiry method does not matter as long as the inquiry content can be identified.

Next, the terminal device 3 acquires position information regarding the position of the terminal device 3 (step S2). The position information can be acquired, for example, by receiving a signal from a GPS (Global Positioning System).

Next, the terminal device 3 transmits information including the content received in step S1 and the position information acquired in step S2 to the server device 1 (step S3). The server device 1 receives the information transmitted from the terminal device 3 (step S4).

Next, the server device 1 analyzes the words and/or sentences included in the inquiry content from the user by the language specifying unit 103, and specifies the language used by the user (step S5). An existing technique such as morphological analysis or character code analysis can be used to analyze the inquiry content.

Next, the server device 1 converts the content of the inquiry from the user into a predetermined language (step S6). The predetermined language may be, for example, Japanese or English. As an example, the predetermined language will be described below as Japanese. For conversion into Japanese, for example, the API of the translation program may be used. If the language specified in step S5 is Japanese, the conversion process in step S6 may be omitted.

Next, the server device 1 retrieves information from the reply information stored in the reply storage unit 104 using the language specified by the language specifying unit 103 and the inquiry content received by the inquiry receiving unit 101. (Step S7).

[Answer master table]
FIG. 4 is a diagram showing an answer master table and a search result corresponding to at least one of the embodiments of the present invention. FIG. 4A shows an answer master table stored in the answer storage unit 104. The answer master table 200 stores at least the answer 203 in association with the language 201 and the inquiry content 202.

The language 201 represents the language used by the user. The inquiry content 202 represents a question inquired by the user. The answer 203 is an answer determined based on the language 201 and the inquiry content 202.

As shown in the figure, when the language 201 is "common to all languages", the same answer 203 is returned regardless of which language the inquiry is made. When the language 201 is “Chinese”, for example, the answer 203 may indicate a phone number corresponding to Chinese. In this way, by changing the inquiry destination for each language used by the user, it is possible to provide an answer that does not give stress to the user.

Next, the server device 1 measures the degree of matching, which is the degree to which the retrieved information includes words and/or sentences related to the inquiry content (step S8). The degree of matching means, for example, the degree of inclusion of words and/or sentences related to the content of an inquiry from the user. As a method of measuring the degree of matching, for example, as in the case of HITS (Hypertext Induced Topic Selection) algorithm, not only the matching rate with respect to the keyword is high, but also the page actually evaluated by many users as useful information. It is possible to adopt a method of scoring high.

[First search processing and measurement of matching degree]
The first search process in step S7 and the matching degree measurement in step S8 will be described more specifically. For example, a case will be described in which the user inputs "Chinese water leaks" in Chinese in step S1. In step S5, the server device 1 specifies the language used by the user as “Chinese”. Then, in step S6, "the kitchen water leaks" is converted into Japanese. Here, as an example, “kitchen”, “water”, and “leakage” are extracted as keywords by morphological analysis. Then, the answer 203 is identified based on the language 201 that matches the “Chinese” used by the user and the inquiry content 202 that matches “kitchen”, “water”, and “leakage” extracted as keywords. It

FIG. 4B shows an example of the result of the search performed based on the words “Chinese” and the words “kitchen”, “water”, and “leakage”. For example, if the language 201 is “Chinese” and all of the keywords “kitchen”, “water”, and “leakage” are included, the matching degree is 1.0. On the other hand, for example, when the answer 203 does not include only “kitchen”, the matching degree may be 0.66. The numerical value of the degree of matching can be designed to be larger as the degree of matching with the search condition is higher. Further, if the information is included in a specific domain, the matching degree may be corrected by increasing the matching degree.

Returning to the flowchart of FIG. In the server device 1, the degree-of-match determination unit 108 determines whether the degree of match measured in step S8 satisfies a predetermined criterion (step S9). The criterion may be determined based on an arbitrary condition, and for example, when there is no answer 203 having a matching degree of 0.5 or more, it may be determined that the criterion is not satisfied.

When the criterion is satisfied in step S9 (YES in step S9), the server device 1 rearranges the search results as shown in FIG. 8B in descending order based on the matching degree (step S14). .. In other words, the matching contents are rearranged so as to be displayed in the higher rank. When the criterion is not satisfied (NO in step S9), the server device 1 causes the second search unit 109 to acquire the position information of the terminal device acquired by the position information acquisition unit 102, the specified language, and the acceptance. Information is retrieved from the Internet using the inquired contents (step S10), and the degree of matching is measured (step S11) as in the first retrieval.

Next, the server device 1 searches the information on the Internet using the specified language and the received inquiry content by the third search unit 110 (step S12), and matches the same as the first search. The degree is measured (step S13).

[Second search process]
For example, in step S1, when the user inputs the inquiry content of "delicious shop" in "Arabic", the sentence "Arabic" and the phrase "delicious shop" are used, 1 Perform a search. When it is determined in step S9 that the predetermined matching degree is not satisfied, the position information of the terminal device 3 and the search condition used in the first search are used to search for information on the Internet. By doing so, even if the question has a low relevance to the real estate management business, it is possible to provide the answer of the language used by the user and the current position, and the convenience of the user can be improved. ..

[Third search processing]
When the same search condition as the above-described second search process is used, information is searched for on the Internet using the search condition used in the first search. Compared with the second search process, this is a search without using the position information of the terminal device 3. By doing so, even if the question has a low relevance to the real estate management business, the answer in the language used by the user can be provided, and the convenience for the user can be improved. In addition, by responding to general inquiries regarding real estate, etc., other than management inquiries, the user is motivated to use the system according to the present invention as a search tool and contributes to improving the accuracy of information. obtain. By gradually expanding the search range from specialized content to general content, it is possible to shorten the time until an answer is obtained, as compared with searching from a vast amount of information.

Then, the server device 1 rearranges the information by the rearrangement unit 111 based on the matching degree attached to each retrieved information (step S14). The server device 1 transmits the search result to the terminal device 3 (step S15). The terminal device 3 receives the transmitted search result (step S16). The terminal device 3 displays the received search result on the display screen (step S17), and ends.

In the above description, an example in which the reply 203 is stored in the reply master table 200 with the language 201 and the inquiry content 202 as keys has been described, but the present invention is not limited to this. FIG. 5 is a diagram showing an answer master table corresponding to at least one of the embodiments of the present invention. At least an answer 304 is stored in the answer master table 300 in association with the room 301, the language 302, and the inquiry content 303.

The room 301 represents the position information of the room with which the user of the terminal device 3 has a contract. The language 302, the inquiry content 303, and the answer 304 can adopt the same definitions as the language 201, the inquiry content 202, and the answer 203, respectively.

If the property to be managed is, for example, a room on the higher floor of a tower condominium, there is a risk that it will shake significantly if an earthquake occurs. Foreigners unfamiliar with earthquakes often do not know what to do in the event of an earthquake. Therefore, for each language, information such as what to do in the event of an earthquake and where to evacuate may be indicated. On the other hand, Japanese people are less likely to feel uneasy than foreigners even if they omit the information such as the earthquake-resistant structure. Therefore, the information can be omitted and stored.

In addition, there are cases where complaints are received that "the residents on the upper floors are noisy and noisy". In such a case, the room number may be specified based on the positional relationship based on the information of the room 301, such as "Room 303," in the answer 304. Alternatively, the design may be such that a question is returned to ask for further user input, such as "Do you know which room on the third floor?".

The room 301 is not limited to the room. For example, it may be a single building or a single house, or may designate a township or a region. For example, it is possible to further improve the convenience by including a method of disposing of oversized waste in the area, and including an explanation of the store in the case of purchasing a waste disposal ticket. As in this example, by identifying the position where the terminal device 3 exists as the reference position and the relative position that is the answer from the inquiry content, unnecessary questions can be reduced and user convenience can be improved.

In the above description, after performing the first search process, it is determined whether or not the matching degree satisfies a predetermined criterion, but the present invention is not limited to this. You may make it perform all 1st search processing, 2nd search processing, and 3rd search processing, without making a determination. Alternatively, the determination may be performed even after the second search process is completed, and the third search process may be performed only when the predetermined criterion is not satisfied.

In the above description, the matching degree is measured every time the search is performed, but the present invention is not limited to this. That is, it is possible to adopt a method of collecting the retrieved results and measuring the degree of coincidence collectively. By doing so, the processing load on the server device 1 can be reduced.

In the above description, the answer of the first search process is stored as the answer master table, but the answer data may be stored in the web page format under the predetermined domain. Further, it may be set so as to increase the matching degree with respect to the information retrieved from the web page under the specific domain. By doing so, it is possible to perform the search and the matching degree in the same process as the second search and the third search, reduce unnecessary processes, and speed up the process of the entire system.

In the above description, the element that specifies the user attribute is only the language, but it may be derived from the language to specify a more detailed attribute. For example, when an Arabic input is accepted, it may be estimated that the religion believed by the user is Islam. By doing this, it is possible to make proposals to Muslim users that are more in line with their needs, such as introducing restaurants that offer Halal dishes that use ingredients permitted by Islamic law. , The convenience of the system can be improved.

In the present invention, the user may evaluate the retrieved answer. The search results may be designed to be adjusted based on this evaluation. By doing so, the answer information frequently used by the user is displayed in a more prominent position, and the convenience of the system can be improved.

In the above description, the method of not registering the attributes of the user in advance has been described. However, for example, the management company may register in advance information about the attributes of the user, which needs to be filled in the rental contract of the apartment or the accommodation contract of the hotel. May be. By doing so, it is possible to provide an answer that better meets the needs of the user, and it is possible to increase the satisfaction level of using the system.

In the case of a method of registering user attributes, a blacklist of users may be created by feeding back evaluations from other users. For example, as shown in FIG. 5, by accepting a negative evaluation for a user who is annoying and disturbing on the floor, the next time the noisy user uses the real estate property, it may be rejected. Good. On the other hand, a positive evaluation may be given to a user who has no complaints during the contract period, and the usage fee of the real estate property or the like may be changed according to the evaluation.

INDUSTRIAL APPLICABILITY The present invention can provide a system that can be used without stress for a user who uses any language by associating and storing an answer for each language.

The present invention, when an inquiry is received in a language other than the predetermined language, by converting the search into a predetermined language and performing a search, it is sufficient to maintain the answer master table only in the predetermined language. The management company that manages is no longer required to have personnel who are good in multiple languages, and the load on the management company can be reduced.

The present invention covers not only stored answers but also general questions as well as specialized questions by retrieving information from the Internet, which are less relevant to real estate management operations. Therefore, the convenience of the user can be improved.

In the above description, the concierge service of a management company for real estate or the like has been described as an example, but the present invention is not limited to this. It is also possible to appropriately change the described contents and apply it to a convenience store or a tourist information center, for example.
