　（本発明の概要）
　図１は、本発明にかかる地理空間情報生成装置を示している。地理空間情報生成装置１００は、情報流通サイト上で入手可能な元情報を収集する収集部１１０と、当該元情報に対し、当該元情報に関連する施設情報を付与して地理空間情報を生成する付与部１２０とを備える。 (Summary of the Invention)
FIG. 1 shows a geospatial information generation apparatus according to the present invention. The geospatial information generation apparatus 100 generates geospatial information by adding the facility information related to the source information to the source information and the collection unit 110 for collecting the source information available on the information distribution site. And a provision unit 120.
　収集部１１０が、Ｔｗｉｔｔｅｒ等の情報流通サイトから収集する元情報は、たとえば図２に示されるように表示される。元情報２００には、利用者ＩＤ２０１、投稿時間２０２、場所名２０３、ＵＲＬ２０４、エリア２０５、クチコミ２０６等が含まれる。収集は、情報流通サイトがキーワードサーチ用のＡＰＩを提供している場合には、ＵＲＬを特徴付ける文字列をＡＰＩにリクエストすることにより行うことができる。これにより、ＵＲＬを含む元情報のみを収集することができる。「ｈｔｔｐ：」、「ｈｔｔｐｓ：」等を文字列としてＡＰＩに与えることで、ＵＲＬを含む元情報を効率的に収集することができる。たとえば、Ｔｗｉｔｔｅｒ上で入手可能な元情報、すなわち投稿のうち、ＵＲＬを含むものは発明者らの調べによれば約５％程度であり、本発明の一実施形態では、投稿データの大半を破棄して積極的に解析対象から外し、地理空間情報を生成可能なものの選別を適切に行っている。さらに、ＡＰＩからのレスポンスには、施設情報を関連づけることのできない元情報も含まれる場合があり、これらを除外するために、収集した元情報（レスポンス）データを解析することもできる。Ｔｗｉｔｔｅｒであれば、ｓｏｕｒｃｅタグを解析して、所定のウェブサービス（ｆｏｕｒｓｑｕａｒｅ、ｉｎｓｔａｇｒａｍ等）が発行するＵＲＬを含むものに限定することや、ｔｅｘｔタグを解析して「（１半角スペース）ｈｔｔ（ｐ）」、「（１全角スペース）ｈｔｔ（ｐ）」等を含むものにフィルタリングすることができる（図３（ａ）参照）。 The original information collected by the collection unit 110 from an information distribution site such as Twitter is displayed as shown in FIG. 2, for example. The source information 200 includes a user ID 201, a posting time 202, a place name 203, a URL 204, an area 205, a word of mouth 206, and the like. The collection can be performed by requesting a character string characterizing the URL from the API when the information distribution site provides the API for keyword search. Thereby, only the original information including the URL can be collected. By giving "http:", "https:", etc. as a character string to the API, the original information including the URL can be efficiently collected. For example, the original information available on Twitter, that is, about 5% of postings including URLs among the postings, according to the inventors' investigation, and in one embodiment of the present invention, most of the posting data is discarded. They are actively excluded from the analysis target and appropriately selected those capable of generating geospatial information. Furthermore, the response from the API may include original information to which facility information can not be associated, and in order to exclude these, it is possible to analyze the collected original information (response) data. In the case of Twitter, the source tag is analyzed and limited to those including a URL issued by a predetermined web service (foursquare, instagram, etc.), or the text tag is analyzed to “(1 half-size space) htt (p ), “(1 full-width space) htt (p)”, etc. can be filtered (see FIG. 3A).
　付与部１２０は、元情報２００のＵＲＬ２０４に基づいて、元情報に関連する施設情報を付与することができる。付与部１２０は、ＵＲＬ２０４にアクセスし、ＵＲＬ２０４で表示されるウェブサイトのソースコードをスクレイピング（ウェブ・スクレイピング）して、施設情報を抽出することができる。元情報２００には、場所名２０３の表示があり、これに基づいて施設名を判定することもできるものの、短縮されている場合もあり、これが正確な施設名であるか否かの信頼性は必ずしも高くない。また、そもそも場所名２０３の表示がない場合もある。本発明の一実施形態では、ＵＲＬ２０４を辿ることによって、より信頼性の高い施設名等の施設情報を取得することを可能とする。 The assignment unit 120 can assign facility information related to the original information based on the URL 204 of the original information 200. The giving unit 120 can access the URL 204 and scrape (web scraping) the source code of the web site displayed by the URL 204 to extract the facility information. The source information 200 has a display of the place name 203, and although the facility name can be determined based on this, it may be shortened, and the reliability of whether this is the correct facility name is Not necessarily expensive. In addition, there may be no display of the place name 203 in the first place. In one embodiment of the present invention, it is possible to obtain facility information such as more reliable facility names by tracing the URL 204.
　なお、収集部１１０における収集と、付与部１２０における付与とは、リアルタイムに行うことができる。情報流通サイトによっては、元情報が秒単位で生成されており、このような情報に対するニーズも短期間に生じ、なくなっていくものであるため、情報の鮮度あるいは即時性が極めて重要である。そのため、収集と付与とを秒単位で繰り返すリアルタイム処理が求められる。たとえば、災害、防災等に関する情報のリアルタイム処理に対するニーズが挙げられる。収集については、たとえば、ＡＰＩへのリクエスト元を多重化させることによって、処理速度の高速化を図ることができる。 The collection in the collection unit 110 and the assignment in the assignment unit 120 can be performed in real time. Some information distribution sites generate the original information in seconds, and the need for such information also occurs in a short period of time and disappears, so the freshness or immediacy of the information is extremely important. Therefore, real-time processing that repeats collection and assignment in seconds is required. For example, there is a need for real-time processing of information on disasters, disaster prevention, etc. With regard to collection, for example, the processing speed can be increased by multiplexing request sources to the API.
　地理空間情報生成装置１００は、生成した地理空間情報を携帯端末に送信する送信部１３０をさらに備えることができる。送信部１３０は、当該携帯端末の現在位置から所定の距離内の施設についての地理空間情報を送信することができる。携帯端末では、受信した地理空間情報を閲覧することや、地図上に表示することで、現在位置に密接に関連した情報を入手することができる。たとえば、元情報がクチコミ情報を含む場合には、カーナビ、歩行者・自転車向けのナビゲーションサービス、地域情報サービス等に応用することで、単純な地図、経路情報等ではなく、目的地、現在地等の周囲で注目を集めている施設の存在を簡便に知らせることができる。 The geospatial information generation device 100 may further include a transmitting unit 130 that transmits the generated geospatial information to the mobile terminal. The transmission unit 130 can transmit geospatial information on facilities within a predetermined distance from the current position of the mobile terminal. The mobile terminal can obtain information closely related to the current position by browsing the received geospatial information or displaying it on a map. For example, if the original information includes word-of-mouth information, it can be applied to car navigation systems, navigation services for pedestrians and bicycles, regional information services, etc., and not simple maps, route information, etc. It can be easily informed of the existence of a facility that is attracting attention in the surrounding area.
　（施設情報の付与）
　スクレイピングされるソースコードには、情報流通サイトに元情報を提供するウェブサービスにもよるが、元情報に関連づけられた施設情報、具体的には施設名、経緯度、施設種別等が、解析可能な形で記載されている。どのような形で記載がなされているかは、上述のとおりウェブサービスにより異なることがあるため、ウェブサービスの判定を行ってから、当該ウェブサービスに対応するスクレイピング・ロジックを選択することができる。さらに、同一のウェブサービスから提供される元情報であっても、たとえばＳＮＳへの投稿における画像の有無等、元情報の具体的な内容に応じてソースコードの記述方式が異なることがあるため、具体的な内容に対応するスクレイピング・ロジックを用意しておき、選択することもできる。 (Grant of facility information)
Although the source code to be scraped depends on the web service that provides the original information to the information distribution site, the facility information associated with the original information, specifically the facility name, the latitude and longitude, the facility type, etc. can be analyzed It is described in the form. Since the form in which the description is made may differ depending on the web service as described above, it is possible to determine the web service and then select the scraping logic corresponding to the web service. Furthermore, even if the source information is provided from the same web service, the source code description method may differ depending on the specific content of the source information, such as the presence or absence of an image in posting to SNS, for example. It is also possible to prepare scraping logic corresponding to specific contents and select it.
　ウェブサービスの判定は、情報流通サイトがＴｗｉｔｔｅｒである場合には、文字列とウェブサービスとの対応づけを保持する対応テーブルを参照して、収集部１１０が収集したレスポンスデータのｓｏｕｒｃｅタグ（図３（ａ）参照）に含まれる文字列に基づいて行うことができる。 When the information distribution site is Twitter, the determination of the web service refers to the correspondence table holding the correspondence between the character string and the web service, and the source tag of the response data collected by the collection unit 110 (FIG. 3). (A) can be performed based on the character string included in (a).
　経緯度（緯度経度）は、ソースコードのスクレイピングによって、判定できる場合とできない場合があり、判定できない場合には、判定された施設名に基づいて、施設名と経緯度との対応づけを保持する施設データベースを参照して判定することもできる。この際、元情報の一部、たとえば行政区画等のエリア２０５、レスポンスデータに含まれる経緯度等に基づいて当該施設データベースの参照範囲を当該施設の所在地域と推定される範囲に限定してから、施設名に基づいて参照することで、判定精度を高めることができる。このようにすることで、同一の施設名ではあるものの、大きく離れた施設と判定されてしまうことを、たとえば防ぐことができる。この際、推定所在地域への限定をあらかじめ行っておくと、表記揺れに対する対応を要する施設名のマッチング処理数を減少させることができる。エリア２０５は、元情報のレスポンスデータでは、たとえば図３（ｂ）のように記述される。 The latitude and longitude (latitude and longitude) may or may not be determined by scraping the source code, and if it can not be determined, the association between the facility name and the latitude and longitude is retained based on the determined facility name. It can also be determined by referring to the facility database. At this time, the reference range of the facility database is limited to a range estimated to be the location area of the facility based on a part of the original information, for example, the area 205 such as an administrative division, and the degree of longitude included in the response data. The determination accuracy can be enhanced by referring to the facility name. By doing this, it is possible to prevent, for example, determination as a facility which is the same as the facility name but is greatly separated. At this time, if limitation to the estimated location area is performed in advance, it is possible to reduce the number of matching processes of the facility name which needs to cope with the writing fluctuation. The area 205 is described in, for example, the response data of the original information as shown in FIG.
　施設種別は、判定できない場合には、判定された施設名に基づいて、施設名と施設種別との対応づけを保持する施設種別データベースを参照して判定することもできる。また、飲食店、観光施設等に関する情報サイト等のウェブサービスが提供するＡＰＩに、判定された施設名をリクエストし、レスポンスデータを解析することにより、施設種別を判定することもできる。この際、施設名に対して、元情報の一部に基づいて当該施設名を補った後に参照をすることで、判定精度を高めることができる。 If the facility type can not be determined, it can also be determined based on the determined facility name, with reference to the facility type database holding the correspondence between the facility name and the facility type. The facility type can also be determined by requesting the determined facility name from an API provided by a web service such as an information site about a restaurant, a tourist facility, etc. and analyzing the response data. At this time, the determination accuracy can be enhanced by referring to the facility name after the facility name is compensated based on a part of the original information.
　住所は、経緯度を変換すること（「逆ジオコーディング」とも呼ばれる。）により取得可能である。 The address can be obtained by converting the latitude and longitude (also called "inverse geocoding").
　（地理空間情報の分析）
　上述のように生成される地理空間情報は、元情報が密接に関連する地点又は区域を特定するものであるため、様々な活用が可能となる。 (Analysis of geospatial information)
Since the geospatial information generated as described above identifies points or areas to which the original information is closely related, various applications are possible.
　たとえば、特定の地点又は区域に関連づけられた、過去から現在までの地理空間情報のすべて又は一部を集計して混雑具合、人気度、話題度、魅力度、危険度等の各種のスコアを算出することができる。特定の施設に関連づけられた地理空間情報の量を集計すれば、その施設が注目の時点、時間帯、時期、又は期間においてどの程度混雑しているかを評価することができる。また、地理空間情報の量のみならず、各地理空間情報が写真を含むか否かによって重み付けして集計することで、写真を含む投稿は魅力が高いと感じられる傾向にあるため、その施設の魅力度を評価することができる。また、施設名に「駅」が含まれる場合には、魅力度の評価においてはそのような元情報を除外することで、乗降客数が１日平均数十万人にのぼるような駅が単に混雑しているのみにも関わらず魅力度が高い施設として評価されてしまうことを避けることができる。また、投稿に含まれる文字列に危機管理関係の所定のキーワードが含まれているか否かにより重み付けをすることにより、危険度を評価することができる。このような各種スコアは、民間企業のマーケティング、公的機関における危機管理、一般コンシューマー、旅行者等に対する人気情報・流行情報の提供等、多様な場面での活用が見込まれる。 For example, all or part of the geospatial information from the past to the present, which is associated with a specific point or area, is aggregated to calculate various scores such as congestion degree, popularity degree, topic degree, attraction degree, risk degree can do. By aggregating the amount of geospatial information associated with a particular facility, it is possible to assess how crowded the facility is at the time, time, time or period of interest. In addition, it is not only the amount of geospatial information, but it is weighted by totaling whether each geospatial information contains a photograph, and it is because the post including a photograph tends to be felt attractive. The degree of attraction can be assessed. In addition, when the station name is included in the facility name, by excluding such original information in the evaluation of attractiveness, stations where the number of passengers gets to an average of several hundred thousand per day are simply crowded It is possible to avoid being evaluated as a highly attractive facility despite the fact that you are doing it. Also, the degree of risk can be evaluated by weighting based on whether or not the character string included in the post includes a predetermined keyword related to crisis management. Such various scores are expected to be used in various situations, such as marketing of private enterprises, crisis management in public organizations, and provision of popular information and trendy information to general consumers, tourists, etc.
　一例としては、地理空間情報に含まれる文字列の言語に応じた重み付けをして集計することにより、特定の文化圏を対象としたスコア算出を行うこともできる。中国人観光客向けにある地域で人気の高い施設を知らせるためには、たとえば当該地域に関連づけられたＳＮＳへの投稿データを、写真を含み、かつ、中国語の文字列を含む投稿データのみにフィルタリングすることによって、中国人観光者向けの人気施設ランキングを提供することができるようになる。このような行動傾向の分析がアンケート等の事前準備をすることなく可能になる点は地理空間情報の用途を大きく拡げることとなる。 As an example, it is also possible to calculate a score for a specific culture area by performing weighting according to the language of character strings included in geospatial information and totaling. In order to inform popular facilities in a region for Chinese tourists, for example, post data to the SNS associated with the area should be only for post data that includes photos and contains Chinese characters. By filtering, it will be possible to provide popular tourist rankings for Chinese tourists. The point at which such analysis of behavioral tendency can be made without preparing in advance such as a questionnaire greatly expands the application of geospatial information.
　（各種データベース）
　地理空間情報を蓄積することでデータベースの構築が可能であり、各レコードは、元情報に加えて、施設名、施設種別、経緯度、住所等を含むことができる。さらに、各施設を一意に特定する施設ＩＤを加えてもよい。元情報がＳＮＳへの投稿データである場合には、当該データベースは、利用者ＩＤ、投稿ＩＤ、投稿テキスト、投稿画像、日付等をさらに含むことができる。これらの情報に基づいて、各種の特定用途のデータベースを構築することができる。 (Various databases)
By accumulating geospatial information, construction of a database is possible, and each record can include facility name, facility type, latitude and longitude, address, etc. in addition to the original information. Furthermore, you may add plant | facility ID which identifies each plant | facility uniquely. When the original information is post data to SNS, the database can further include a user ID, a post ID, a post text, a post image, a date, and the like. Based on these pieces of information, various special purpose databases can be constructed.
　「施設データベース」として、施設ＩＤ、施設名、施設種別、経緯度、及び住所で構成されるデータベースを構築することができる。各施設について、人気度等のスコアを算出しておいてもよい。 As "facility database", a database composed of facility ID, facility name, facility type, latitude and longitude, and address can be constructed. For each facility, scores such as popularity may be calculated.
　「利用者データベース」として、利用者ＩＤに基づいて当該利用者の居住エリア、勤務エリア、性別、職業、年齢等を判定して各利用者の属性で構成されるデータベースを構築することができる。利用者データベースが構築されていると、たとえば、元情報に含まれる文字列の言語分析の代わりに、元情報の発信者の居住エリアによりフィルタリングをすることで、特定の文化圏あるいは出身地向けの魅力度を評価することができる。 As the “user database”, it is possible to construct a database configured of the attributes of each user by determining the residence area, work area, gender, occupation, age, etc. of the user based on the user ID. If a user database is constructed, for example, instead of linguistic analysis of strings contained in the original information, filtering by the residence area of the originator of the original information is performed for a specific cultural area or birthplace. The degree of attraction can be assessed.
　「エリア特徴データベース」として、エリア（区域）、時間又は時間帯、平日又は休日、エンターテインメント指数、飲食指数、夜指数、旅行指数、宿泊指数、アウトドア指数、女性指数、男性指数、旅行者指数、居住者指数、外国人指数等により構成されるデータベースを構築することができる。地球上に存在する各エリアに対して、その場所のもつ複合的な特徴等を算出することができる。たとえば、渋谷液半径１ｋｍエリアの休日午後３時台のエンターテインメントを算出することによって、当該エリアの該当時間における消費者のエンターテインメント行動の傾向を表すことができる。 Area (area), time or time zone, weekday or holiday, entertainment index, eating and drinking index, night index, travel index, accommodation index, outdoor index, female index, male index, traveler index, residence as “area feature database” It is possible to construct a database composed of the index of foreigners, index of foreigners, etc. For each area present on the earth, it is possible to calculate the complex features of the place. For example, it is possible to express the tendency of the consumer's entertainment behavior at the corresponding time of the area by calculating the entertainment at around 3 o'clock pm on holidays in the area with a radius of 1 km in the Shibuya liquid.
　生成された行動情報から所定のエリアに関連づけられたものを抽出し、時間又は時間帯及び休日平日は、元情報２００に含まれる投稿時間２０２等から得ることができる。エンターテインメント指数は、「地理空間情報」と「利用者データベース」と「施設データベース」を使って日々の消費者のエンターテインメント施設に関わる行動と利用者特徴と施設特徴を掛けあわせて集計することにより得ることができる。また、その他の指数も同様である。 From the generated action information, one associated with a predetermined area is extracted, and a time or a time zone and a holiday weekday can be obtained from the posting time 202 and the like included in the original information 200. Entertainment index is obtained by multiplying daily consumer's entertainment facility related activities and user characteristics and facility characteristics using "geography spatial information", "user database" and "facility database" Can. The other indices are also the same.
　たとえば、ある人物の移動履歴として人物ＩＤ、経緯度、時間又は時間帯等があるとき、エリア特徴データベースの各指数を複合的に組み合わせることにより自動的に人物の特徴（シルエット情報）を算出することができる。移動履歴に含まれる経緯度及び時間又は時間帯に基づいてエリア特徴データベースを参照することで、特定のエリア、時間又は時間帯、平日又は休日において高い値を取る指数を読み出し、当該人物の特徴が分かるのである。 For example, when there is a person ID, longitude and latitude, time or time zone as a movement history of a person, the feature (silhous information) of the person is automatically calculated by combining each index of the area feature database. Can. By referring to the area feature database based on the latitude and longitude and time or time zone included in the movement history, an index that takes a high value in a specific area, time or time zone, weekday or holiday is read out, and the person's feature is I know.
　渋谷駅半径１ｋｍエリアの休日午後３時台のエンターテインメント指数等、各エリアを特徴づける指数が分かると、インターネット広告配信時の配信ターゲットの特定に有効な指標を提供することができる。具体的には、渋谷駅半径１ｋｍエリアに休日午後３時台にスマートフォンデバイスを利用している消費者に広告を配信する場合に、その場でインターネット広告配信事業者が渋谷駅半径１ｋｍエリアの休日午後３時台の各種指数を参照することで、より消費者の状況に合った広告の配信ができる。他にも、ショッピングセンターの出店計画、屋外広告、広告配信に最適なエリアや時間帯を自動的に算出することも可能である。 Knowing the indexes that characterize each area, such as entertainment indexes at around 3 pm on a holiday at a radius of 1 km in Shibuya Station radius, it is possible to provide an effective index for specifying a delivery target at the time of Internet advertisement delivery. Specifically, when an advertisement is delivered to a consumer using a smartphone device at 3:00 pm on a holiday in the Shibuya station radius of 1 km area, an Internet advertisement distribution provider on the spot is a holiday at the Shibuya station radius of 1 km area By referring to the various indexes in the 3 pm range, it is possible to deliver advertisements more in line with consumer conditions. In addition, it is also possible to automatically calculate the area and time zone that are optimal for shopping center opening plans, outdoor advertisements, and advertisement distribution.
