Description

本発明は、情報端末装置の所持者が、当該情報端末装置から情報提供装置にアクセスして、その地図データべースから地図情報を取得するとき、その地図のエリアの施設など各種の情報（領域情報）を提供する情報提供装置、情報提供システム、プログラム及び情報提供方法に関する。   In the present invention, when the owner of an information terminal device accesses the information providing device from the information terminal device and acquires map information from the map database, various information such as facilities in the area of the map ( The present invention relates to an information providing apparatus, an information providing system, a program, and an information providing method.

ＧＰＳ（Global Positioning System）受信機能付きの移動通信端末装置が普及してきたことにより、例えば移動端末装置の位置情報に関連付けて店舗などの広告を提供するシステムが多く開発されている。
例えば、携帯電話機などの移動端末装置の位置と店舗の位置との関係に基づき、移動端末装置の近くにある店舗の広告データを当該移動端末装置に配信する広告配信システム（特許文献１参照）、或いは、センターのサーバ装置が、顧客から予め取得した目的地情報と顧客の所持する移動体の位置情報に基づき、顧客が目的地に近づくと、その目的地の近くにある商店の商店情報を生成して携帯機器に送信する顧客位置管理システム（特許文献２参照）、さらに、地図データと、地域ごとの娯楽情報をまとめた娯楽情報データとを有するサーバ装置を備え、ユーザが当該サーバ装置にアクセスして地図データ上の地域を指定することにより、指定した地域の娯楽情報を表示するようにした娯楽情報検索システムが知られている（特許文献３参照）。 With the widespread use of mobile communication terminal devices with GPS (Global Positioning System) reception function, for example, many systems have been developed that provide advertisements such as stores in association with location information of mobile terminal devices.
For example, based on the relationship between the position of a mobile terminal device such as a mobile phone and the location of a store, an advertisement distribution system that distributes advertisement data of a store near the mobile terminal device to the mobile terminal device (see Patent Document 1), Alternatively, when the customer approaches the destination based on the destination information acquired in advance from the customer and the position information of the mobile object possessed by the customer, the center server device generates store information of the store near the destination. And a server device having map data and entertainment information data in which entertainment information for each region is collected, and the user accesses the server device. An entertainment information retrieval system that displays entertainment information in a specified area by specifying an area on map data is known (see Patent Document 3). ).

特許文献１及び２に記載されたシステムでは、情報端末装置つまり、ユーザ（顧客または利用者）の位置情報に基づきタイミング良くサービス情報を提供しようとするものであるから、ユーザが実際に現地にいることが前提である。また、特許文献３に記載されたシステムでは、ユーザが指定した地域の情報を提供することができるため、例えば旅行などを計画している利用者にとっては便利である。
しかし、このシステムは、提供情報が娯楽に限られていることに加え、情報端末装置即ちユーザの現在の所在地とは関係なく、ユーザが指定した地域の情報をそのまま提供するものである。
しかし、実際には、ユーザが指定した地域の近隣に居るか遠隔地に居るかで、その地図検索の目的或いは提供される情報に対するニーズは異なることが多いと思われるが、上記システムではそのようなニーズに十分対応できていない。 In the systems described in Patent Documents 1 and 2, the information terminal device, that is, the user (customer or user) intends to provide service information in a timely manner based on the location information of the user, so the user is actually at the site. That is the premise. In addition, the system described in Patent Document 3 can provide information on a region designated by the user, which is convenient for a user who plans a trip, for example.
However, this system provides the information of the area designated by the user as it is regardless of the information terminal device, that is, the current location of the user, in addition to the provided information being limited to entertainment.
In practice, however, the purpose of the map search or the need for the information provided is likely to differ depending on whether it is in the vicinity of the area specified by the user or in a remote place. Is not enough to meet the needs.

例えば、指定した地図からみて遠隔地のユーザからみれば、娯楽情報などの日常的な情報よりも、宿泊情報などの非日常的な情報が必要であるが、このシステムでは指定した地図とユーザの現在位置との関係についてその遠近については考慮されていないため、そのようなきめの細かい情報提供は不可能である。   For example, from the point of view of a specified map, it is necessary to have extraordinary information such as accommodation information rather than daily information such as entertainment information. Since the distance to the current position is not taken into consideration, it is impossible to provide such detailed information.

即ち、従来の広告などの情報提供は、地図情報に基づくものが多く知られているが、いずれも地図で指定したあるいは、地図上の位置に近づいたときに情報を提供することが主眼であって、地図情報にアクセスしてきたユーザの現在位置との距離については考慮されていない。   In other words, many of the conventional information provisions such as advertisements are based on map information, but all of them are mainly intended to provide information when specified on the map or when approaching a position on the map. Thus, the distance from the current position of the user who has accessed the map information is not considered.

また、サーバ装置にアクセスして地図情報を取得し、これを情報端末装置の画面に表示する場合、表示された地図の各地域別に、例えばビジネスホテルが集中している地域、或いは高級ホテル・旅館が集中している区域など区域毎に特徴があれば、地図上で各地域毎に色分け等によりその地域の特徴を表示できれば便利である。   In addition, when the map information is acquired by accessing the server device and displayed on the screen of the information terminal device, for example, the region where the business hotel is concentrated or the luxury hotel / inn for each region of the displayed map If there is a characteristic for each area such as an area where the concentration is concentrated, it is convenient if the characteristics of the area can be displayed by color coding or the like for each area on the map.

まず、情報端末装置４は、情報提供サーバ装置２に対し、接続要求を送信する（Ｓ１０１）。この接続要求には、情報端末装置４の端末装置識別情報、例えば携帯電話番号、ＩＰアドレス、必要に応じてユーザＩＤ、パスワード等が含まれている。接続要求が情報提供サーバ装置２の通信部２１で受信されると（Ｓ１０２）、情報提供サーバ装置２側の処理がスタートする。
即ち、その通信制御手段２０１は、地図情報検索画面を情報端末装置４へ送信する（Ｓ１０３）。 Next, a processing procedure when the user requests the provision of map information by accessing the information providing server device 2 from the information terminal device 4 will be described.
FIG. 3 is a flowchart showing a procedure for making a map information request from the information terminal device 4 to the information providing server device 2.
First, the information terminal device 4 transmits a connection request to the information providing server device 2 (S101). This connection request includes terminal device identification information of the information terminal device 4, for example, a mobile phone number, an IP address, and a user ID, a password, etc. as necessary. When the connection request is received by the communication unit 21 of the information providing server device 2 (S102), processing on the information providing server device 2 side starts.
That is, the communication control unit 201 transmits a map information search screen to the information terminal device 4 (S103).

情報端末装置４のユーザは、情報提供サーバ装置２から送信された地図情報検索画面を表示して（Ｓ１０４）、地図を選択するか、或いは地名を入力することにより情報提供サーバ装置２に対して、地図情報の提供要求つまり要求入力を行う（Ｓ１０５）。   The user of the information terminal device 4 displays the map information search screen transmitted from the information providing server device 2 (S104), and selects the map or inputs the place name to the information providing server device 2. Then, a request for providing map information, that is, a request input is performed (S105).

情報提供サーバ装置２は、通信制御手段２０１がこの地図情報要求を受信すると（Ｓ１０６）、上記要求中の各種情報（端末識別情報、要求受付時刻、位置情報）を履歴情報管理手段２０３に渡すとともに、要求対象地図を地図情報管理手段２０２に渡し、地図情報管理手段２０２はその読出手段により、地図情報ＤＢ２２１から要求された地図情報を読み出す（Ｓ１０７）。距離計算手段２０５は、情報端末装置４の所在位置の位置情報（経度・緯度情報）と、読み出した地図の位置情報（例えば、中心位置の経度・緯度情報：或いは特定の位置（駅など）を位置情報に設定してもよい）に基づき両位置間の距離を算出する（Ｓ１０８）。   When the communication control unit 201 receives this map information request (S106), the information providing server device 2 passes various information (terminal identification information, request reception time, location information) in the request to the history information management unit 203. The requested map is passed to the map information management means 202, and the map information management means 202 reads the requested map information from the map information DB 221 by the reading means (S107). The distance calculation means 205 obtains the position information (longitude / latitude information) of the location of the information terminal device 4 and the position information of the read map (for example, the longitude / latitude information of the center position: or a specific position (station, etc.)). The distance between the two positions is calculated based on the position information (S108).

領域情報管理手段２０４は、前記算出した距離に基づき領域情報ＤＢ２２３から前記距離で区分した検索項目リストを読み出し（Ｓ１０９）、その検索項目リストを情報端末装置４に送信する（Ｓ１１０）。情報端末装置４はその表示部４２の表示画面に送信された地図情報とともに検索項目リストを表示し（Ｓ１１１）、ユーザは検索項目を選択する（Ｓ１１２）。   The area information management means 204 reads a search item list classified by the distance from the area information DB 223 based on the calculated distance (S109), and transmits the search item list to the information terminal device 4 (S110). The information terminal device 4 displays the search item list together with the map information transmitted on the display screen of the display unit 42 (S111), and the user selects the search item (S112).

選択された検索項目は情報提供サーバ２に送信される（Ｓ１１３）。情報提供サーバ２に送信された検索項目は、領域情報管理手段２０４に渡され、ここで、領域情報管理手段２０４は、渡された検索項目を上記距離の区分毎に計数（累計）し（Ｓ１１４）、その計数値を領域情報ＤＢ２２３の検索頻度テーブルに格納し（Ｓ１１５）、上記計数値に基づき検索項目リストを見直し、必要に応じて検索項目リストに対して、上記計数値つまり頻度数を反映させて更新し（Ｓ１１６）、かつ領域情報ＤＢ２２３から、上記検索項目に基づき領域情報を読み出す（Ｓ１１７）。
また、領域情報管理手段２０４は地図情報管理手段２０２から受け取った地図を編集する処理（例えば、地図情報を構成するブロックの一部を他のブロックと区別できるように網掛け、着色処理、或いは文字の記入の処理など）を行う（Ｓ１１８）。情報提供サーバ装置２は、上記編集された地図情報と領域情報を、情報端末装置４に送信し（Ｓ１１９）、情報端末装置４ではその情報を表示部４２の表示画面に表示する（Ｓ１２０）。 The selected search item is transmitted to the information providing server 2 (S113). The search items transmitted to the information providing server 2 are transferred to the area information management means 204, where the area information management means 204 counts (accumulates) the transferred search items for each distance category (S114). The count value is stored in the search frequency table of the area information DB 223 (S115), the search item list is reviewed based on the count value, and the count value, that is, the frequency number is reflected in the search item list as necessary. Then, the region information is updated (S116), and the region information is read from the region information DB 223 based on the search item (S117).
Further, the area information management unit 204 edits the map received from the map information management unit 202 (for example, shading, coloring processing, or text so that a part of the blocks constituting the map information can be distinguished from other blocks). (S118). The information providing server device 2 transmits the edited map information and area information to the information terminal device 4 (S119), and the information terminal device 4 displays the information on the display screen of the display unit 42 (S120).

ここで、ユーザが情報端末装置４の表示部４２の表示画面から再度検索項目を選択すると（Ｓ１２１）、選択された検索項目は情報提供サーバ装置２に送信される（Ｓ１２２）。領域情報管理手段２０４は、上記検索項目に該当する領域情報を領域情報ＤＢ２２１から読み出し（Ｓ１２３）、それと共に、必要に応じて地図情報管理手段２０２から受け取った地図の拡大処理や上述の編集処理を行い（Ｓ１２４）、上記編集された地図情報と領域情報を、情報端末装置４に送信し（Ｓ１２５）、情報端末装置４ではその情報を表示部４２の表示画面に表示する（Ｓ１２６）。
以下、同様の処理を、ユーザが最終的に必要とする領域情報を得るまで継続する。 When the user selects a search item again from the display screen of the display unit 42 of the information terminal device 4 (S121), the selected search item is transmitted to the information providing server device 2 (S122). The area information management unit 204 reads out the area information corresponding to the search item from the area information DB 221 (S123), and at the same time, performs the enlargement process of the map received from the map information management unit 202 and the editing process described above as necessary. In step S124, the edited map information and area information are transmitted to the information terminal device 4 (S125), and the information terminal device 4 displays the information on the display screen of the display unit 42 (S126).
Hereinafter, the same processing is continued until the user finally obtains area information necessary.

図４は、ある特定の地図に対応させた、当該地図が表す地域における検索項目の選択回数を表示した検索頻度テーブルを示す。
領域情報管理手段２０４は、地域情報の検索項目が選択される回数をカウントして上記検索頻度テーブルの検索回数を更新する。
例えば、グルメの検索回数は、０〜５ｋｍ未満の地図情報の取得要求がなされた場合は、１００回であり、５ｋｍ以上〜１０ｋｍ未満では１５０回、・・２００以上では１０回であるとし、これに対し、ホテルの検索回数は、例えば、０〜５ｋｍ未満では０回、５ｋｍ以上〜１０ｋｍ未満では３回、２００ｋｍ以上では５０回であるとする。その場合、検索項目リストの表示順位は、近隣、例えば１０ｋｍ未満の地図の表示を行うときは、検索項目としてグルメをホテルよりも優先順位を上げた表示を行う。また、場合によっては検索項目としてホテルは表示しなくともよい。逆に、２００ｋｍ以上では、ホテルの表示を優先し、グルメはその表示の優先順位を下げるか、または、表示しないようにすることもできる。
既に述べたように、表示画面における領域情報についての検索項目は、その検索頻度に応じて例えば表示の優先順位を変更する。この場合、通年の累積頻度で、或いは各時期毎に、又はリアルタイムで上記頻度表を更新して検索項目リストの検索項目を表示することができる。また、情報端末を特定することにより、操作端末ごと、つまり、ユーザ毎に検索項目リストを作成することもできる。 FIG. 4 shows a search frequency table that displays the number of selections of search items in the area represented by the map, corresponding to a specific map.
The area information management means 204 updates the number of searches in the search frequency table by counting the number of times the search item of the area information is selected.
For example, the number of searches for gourmets is 100 times when a request for obtaining map information of 0 to less than 5 km is made, 150 times for 5 to 10 km, and 10 times for 200 or more. On the other hand, the number of times of searching for a hotel is, for example, 0 for less than 0 to 5 km, 3 for 5 to 10 km, and 50 for 200 or more. In that case, when the display order of the search item list is to display a map of neighborhood, for example, less than 10 km, gourmet is displayed as a search item with a higher priority than the hotel. In some cases, hotels may not be displayed as search items. On the contrary, at 200 km or more, priority is given to the display of the hotel, and the gourmet can lower the priority of the display or not display it.
As described above, for example, the search item for the area information on the display screen changes the display priority according to the search frequency. In this case, the search items in the search item list can be displayed by updating the frequency table at the accumulated frequency of the whole year, at each time, or in real time. Further, by specifying the information terminal, a search item list can be created for each operation terminal, that is, for each user.

本実施形態によれば、以上のように、情報端末装置４から情報提供サーバ装置２に対して地図情報の要求がなされた場合、情報提供サーバ装置２は、情報端末装置４の識別情報に基づき当該情報端末装置４を特定すると共に、その位置情報に基づきその位置（経度、緯度）を特定し、他方、要求された地図の中心位置を表す位置情報（経度、緯度）を算出し、当該位置と前記情報端末装置４との距離を計算する。
ここでは、得られた距離に基づき、領域情報管理手段２０４は、検索項目リストを領域情報ＤＢ２２３から読み出して、通信制御手段２０１により情報端末装置４に送信し、情報端末装置４ではその表示部４２に、取得要求のあった地図と共に上記検索項目リストを表示する。
そのため、ユーザは、単に地図を検索するだけで、同時に地図の例えば中心位置間からの距離（検索距離）に応じて区分した地域情報項目つまり検索項目リストを自動的に得ることができる。また、表示部４２の表示画面で検索項目を選択すると、領域情報管理手段２０４は、その度毎に検索頻度テーブルを更新し、この検索頻度テーブルを参照して必要時に検索項目リストを更新するため、常に最もニーズの高い検索項目を画面に表示することができる。 According to this embodiment, as described above, when a request for map information is made from the information terminal device 4 to the information providing server device 2, the information providing server device 2 is based on the identification information of the information terminal device 4. The information terminal device 4 is specified, the position (longitude, latitude) is specified based on the position information, and on the other hand, position information (longitude, latitude) representing the center position of the requested map is calculated. And the distance from the information terminal device 4 is calculated.
Here, based on the obtained distance, the region information management unit 204 reads the search item list from the region information DB 223 and transmits it to the information terminal device 4 by the communication control unit 201, and the information terminal device 4 displays the display unit 42. The search item list is displayed together with the map requested to be acquired.
For this reason, the user can automatically obtain a region information item, that is, a search item list classified according to a distance (search distance) from, for example, the center position of the map at the same time by simply searching the map. In addition, when a search item is selected on the display screen of the display unit 42, the area information management unit 204 updates the search frequency table each time and updates the search item list when necessary by referring to the search frequency table. The search items with the highest needs can always be displayed on the screen.

図５は、情報端末装置４の表示部４２における表示例を示す。
領域情報の表示は、地図要求時に指定する地図領域に応じて、例えば都道府県単位、市町村単位、さらにそれ以下の単位でそれぞれ縮尺を代えて表示される。

ここで、ユーザがホテルを選択（クリック又はタッチ）すると、図５Ｂに示す画面に切り替わる。図５Ｂの画面では、検索した地図と共に、地図上の一部に斜線（ハッチング）或いは色分けなどしたブロックが表示され他のブロックと区別して表示される。 FIG. 5 shows a display example on the display unit 42 of the information terminal device 4.
The area information is displayed at different scales, for example, in units of prefectures, cities, towns and villages, or less, depending on the map area specified at the time of requesting the map.
The user clicks or touches on this screen to select, for example, gourmet.
On the searched map display screen, for example, as shown in FIG. 5A, together with the map around the specific station searched, the blank area where the map is displayed, the left side in the illustrated example, as a search item, There are items such as hotels, sightseeing, gourmets, etc.
Here, when the user selects (clicks or touches) a hotel, the screen is switched to the screen illustrated in FIG. 5B. In the screen of FIG. 5B, along with the searched map, blocks with hatching or color coding are displayed on a part of the map and displayed separately from other blocks.

ここでは、情報端末装置４の所在位置と検索した地図の位置とが遠距離、例えば２５０ｋｍ離れている場合の表示例であって、ブロックＡとブロックＢを他のブロックと区別できるように網掛け、ハッチング、色分けなどして表示し、地図領域の一部に、「Ａ：ビジネスホテルの多い地区です。」、「Ｂ：一般旅館・ホテルの多い地区です。」などの説明を表示する。
ここで、例えばブロックＡを選択すると、当該地区のビジネスホテル一覧と、設備、料金、電話番号、メールアドレスやＵＲＬなどが表示され、特定のビジネスホテルを選択すると料金、施設内容、営業時間などが表示され、ＵＲＬを選択すると当該ビジネスホテルのホームぺージを閲覧することができ、ホームページにある予約画面から宿泊予約などができる。
また、表示画面でブロックＢを選択すると、一般旅館やホテル一覧が表示され、表示画面にしたがって操作を行うことで同様に予約などすることができる。 Here, it is a display example when the location of the information terminal device 4 and the position of the searched map are separated by a long distance, for example, 250 km, and is shaded so that the block A and the block B can be distinguished from other blocks. , Hatching, color coding, etc., and a description such as “A: District with many business hotels”, “B: District with many general inns / hotels”, etc. is displayed in a part of the map area.
Here, for example, if block A is selected, a list of business hotels in the area and facilities, charges, telephone numbers, e-mail addresses, URLs, etc. are displayed. If a specific business hotel is selected, the charges, facility contents, business hours, etc. are displayed. When the URL is selected and the URL is selected, the home page of the business hotel can be viewed, and accommodation reservations can be made from the reservation screen on the homepage.
When block B is selected on the display screen, a general inn or hotel list is displayed, and a reservation can be made in the same manner by performing an operation according to the display screen.

情報端末装置４の所在地或いはそこからから近い距離（例えば１０ｋｍ以内）にある地図とともに、領域情報を表示する場合は、上記ホテルや旅館の代わりに、例えばグルメの領域がブロックとして地図上に網掛け、ハッチングや色分けして表示される。その場合におけるユーザの操作は上記ビジネスホテルについて説明したのと同様である。
なお、ショッピングなどのように内容が多種に渡る場合は、ブロックを選択した後に用語検索できるようにして、目的とするショッピング施設例えばデパートを絞り込むように構成する。 When displaying the area information together with the map of the location of the information terminal device 4 or a distance close to it (for example, within 10 km), for example, the gourmet area is shaded on the map as a block instead of the above hotel or inn. , Hatched and color-coded. In this case, the user operation is the same as that described for the business hotel.
In the case of various contents such as shopping, it is possible to search for terms after selecting a block, and to narrow down target shopping facilities such as department stores.

また、図６Ａの表示画面の、「アミューズメント、グルメ、スポーツ、ショッピング、医療など」の検索項目一覧から例えば、グルメを選択すると、次に、和食、洋食、中華、ラーメン、居酒屋などの文字が表示され、同時に地図にブロックＣ、Ｄが表示される。ここで、例えば「ラーメン」を選択すると、図６Ｂに示すように、ラーメン店の多い地区（所定の面積内に存在するラーメン店の数が所定値を超えている地区）が拡大してブロック表示（ブロックＣ）され、同時に「この辺りはラーメン屋が多い地域です」が表示される。さらに、図面には示していないが、ラーメン店の位置を表示地図上に表示して、地図上でラーメン店を選択することで、当該ラーメン店のサービス内容・料金等を表示する。
更に、個々のラーメン店のユーザによる評価を履歴情報として残すシステムとすれば、履歴情報により評価の高いラーメン店を評価順に表示することも、或いはそれぞれの特徴により、ユーザが選択できるようなシステムとして構築することもできる。 In addition, for example, when a gourmet is selected from the search item list of “Amusement, gourmet, sports, shopping, medical, etc.” on the display screen of FIG. 6A, characters such as Japanese, Western, Chinese, Ramen, Izakaya are displayed next. At the same time, blocks C and D are displayed on the map. Here, for example, when “ramen” is selected, as shown in FIG. 6B, the area where there are many ramen shops (area where the number of ramen shops existing within a predetermined area exceeds a predetermined value) is enlarged and displayed as a block. (Block C) is displayed, and at the same time, “This area is full of ramen shops” is displayed. Further, although not shown in the drawing, the position of the ramen store is displayed on the display map, and the service content, fee, etc. of the ramen store are displayed by selecting the ramen store on the map.
Furthermore, if a system that leaves evaluations by users of individual ramen shops as history information, it is possible to display ramen shops with high evaluations based on the history information in the order of evaluation, or as a system that allows the user to select according to their characteristics.
