　（各ＤＢの説明）
　記憶部４０には、レビューＤＢ４２、スコアＤＢ４３、補正値ＤＢ４４、及び加工レビューＤＢ４５が構築されている。 (Description of each DB)
A review DB 42, a score DB 43, a correction value DB 44, and a processed review DB 45 are constructed in the storage unit 40.
　レビューＤＢ４２には、サービス提供装置３が他のサービス提供装置２から取得したレビュー情報、及び（又は）サービス提供装置３がレビュワー端末５から直接取得したレビュー情報が管理されている。 The review DB 42 manages review information acquired by the service providing device 3 from other service providing devices 2 and/or review information directly acquired by the service providing device 3 from the reviewer terminal 5.
　スコアＤＢ４３には、スコア算出部３３によって算出されたスコアが管理されている。 The score DB 43 manages the scores calculated by the score calculation unit 33.
　補正値ＤＢ４４には、スコア補正部３４がスコアの補正に用いる補正値が管理されている。補正値は、各レビュワーの店舗、商品、又はサービスに対する過去の評価に基づき定められた値である。例えば、５段階の評価（数が多い程、評価が高い）のうち、１や２が多いレビュワーの評価に対し、補正値は「1.2」倍、「＋0.5」等を示す。一方、５段階の評価のうち、４や５が多いレビュワーの評価に対し、補正値は「0.8」倍、「－0.5」を示す。この補正値は、取得された過去の複数のレビュー情報に基づいて定められた値である。 The correction value DB 44 manages correction values that the score correction unit 34 uses to correct scores.

This correction value is a value determined based on a plurality of acquired past review information.
　加工レビューＤＢ４５には、スコア平均部３５によって平均化されることで加工されたレビュー情報が管理されている。 The processed review DB 45 manages review information that has been processed by being averaged by the score averaging unit 35.
　（各機能部の説明）
　送受信部３１は、通信ネットワーク１００を介して、サービス提供装置２、レビュワー端末５及びユーザ端末７との間でデータ（レビュー情報等）の送受信を行う。 (Explanation of each functional part)
The transmitting/receiving unit 31 transmits and receives data (review information, etc.) to and from the service providing device 2 , reviewer terminal 5 , and user terminal 7 via the communication network 100 .
　トピック導出部３２は、各レビュワーにより入力された各レビュー情報から、予め定められたカテゴリ（項目）毎に、評価対象のレビュー情報内の自然言語の特徴を示す各トピック(TOPIC)を導出する。例えば、トピック導出部３２は、ツリー構造の辞書、テーブル構造の辞書等を用いて、レビュー情報から、料理、サービス、雰囲気等の各カテゴリに含まれるトピックを導出する。例えば、ツリー構造の辞書では、カテゴリが「料理・味」として上位ノードの場合、下位ノードが「美味しい」、「不味い」等であり、更に「美味しい」の下位ノードが「美味」、「味が良い」等である。テーブル構造の辞書では、カテゴリが「料理・味」としてのテーブルにて、「美味しい」と、「美味」及び「味が良い」等が関連付けて管理されている。 The topic derivation unit 32 derives each topic (TOPIC) indicating the characteristics of the natural language in the review information to be evaluated for each predetermined category (item) from each review information input by each reviewer. For example, the topic derivation unit 32 derives topics included in each category such as food, service, atmosphere, etc. from the review information using a tree-structured dictionary, a table-structured dictionary, or the like. For example, in a tree-structured dictionary, if the category is "cooking/taste" and the upper node is the upper node, the lower nodes are "delicious", "untasty", etc., and the lower nodes of "delicious" are "tasty", "tasty", etc. "Good" etc. In a dictionary with a table structure, "delicious", "delicious", "tasty", etc. are associated and managed in a table with the category "cooking/taste".
　スコア算出部３３は、レビュー情報内の単語の組合せに基づいてレビュー情報の評価の良し悪しを判定すると共に、トピック導出部３２によって導出された各トピックのレビュー情報内における占有率（各トピックが１つのレビュー情報内において占有する割合）に応じて、カテゴリ毎のスコアを算出する。例えば、スコア算出部３３は、各評価対象のレビュー情報に示された、「とても」及び「美味しい」の単語の組合せや、「美味し」及び「くない」単語の組合せ等に基づいて、評価対象のレビュー情報の評価の良し悪しの判定を行う。そして、トピック導出部３２は、「とても」及び「美味しい」の単語の組合せが、「美味し」及び「くない」単語の組合せよりも数が多いために、評価対象のレビュー情報の評価を「良い」と判定した場合、トピック導出部３２によって導出された「料理・味」カテゴリにおけるトピックの数の割合が「30％」、「サービス」カテゴリにおけるトピックの数割合が「20％」等のときには、「料理・味」カテゴリのスコアを「4」にしたり、「サービス」カテゴリのスコアを「3」にしたりする。逆に、トピック導出部３２は、「とても」及び「美味しい」の単語の組合せが、「美味し」及び「くない」単語の組合せよりも数が少ないために、評価対象のレビュー情報の評価を「悪い」と判定した場合、トピック導出部３２によって導出された「料理・味」カテゴリにおけるトピックの数が「30％」、「サービス」カテゴリにおけるトピックの数の割合が「20％」等のときは、「料理・味」カテゴリのスコアを「1」にしたり、「サービス」カテゴリのスコアを「2」にしたりする。 The score calculation unit 33 determines the quality of the evaluation of the review information based on the combination of words in the review information, and also determines the occupancy rate of each topic in the review information derived by the topic derivation unit 32 (each topic The score for each category is calculated according to the percentage of review information occupied by each category. For example, the score calculation unit 33 calculates the evaluation target based on the combination of the words "very" and "delicious", the combination of the words "delicious" and "not delicious", etc. shown in the review information of each evaluation target. Determine whether the review information is good or bad. Then, the topic deriving unit 32 evaluates the review information to be evaluated as "good" because the number of combinations of words "very" and "delicious" is greater than the combination of words "delicious" and "not good." ”, when the proportion of the number of topics in the “Cooking/Taste” category derived by the topic derivation unit 32 is “30%”, the proportion of the number of topics in the “Service” category is “20%”, etc. Set the score for the "Cooking/Taste" category to "4" or set the score for the "Service" category to "3." On the contrary, the topic derivation unit 32 evaluates the review information to be evaluated as "Very" and "Delicious" because the number of combinations is smaller than the number of word combinations "Delicious" and "Not delicious". If the number of topics in the "Cooking/Taste" category derived by the topic derivation unit 32 is "30%" and the ratio of the number of topics in the "Service" category is "20%", etc. , set the score for the "Cooking/Taste" category to "1", or set the score for the "Service" category to "2".
　スコア補正部３４は、補正値ＤＢ４４で管理されているレビュワーの評価傾向に基づく補正値を用いて、スコア算出部３３によって算出された同じレビュワーによるレビュー情報のカテゴリ毎のスコアを補正する。例えば、レビュワーＡが他のレビュー情報においても厳しく評価している場合には、補正値が「1.2」倍、「＋0.5」等であるため、スコア補正部３４は、同じレビュワーＡによる評価対象のレビュー情報の各カテゴリのスコアに対して「1.2」倍したり、「＋0.5」したりする。これにより、スコア算出部３３によって算出された「料理・味」のカテゴリのスコアが「4」の場合、スコア補正部３４は、「1.2」倍して「4.8」に補正する。また、スコア算出部３３によって算出された「サービス」のカテゴリのスコアが「4」の場合、スコア補正部３４は、「1.2」倍して「4.8」に補正する。なお、スコア補正部３４による処理は省略してもよい。 The score correction unit 34 corrects the score for each category of review information by the same reviewer calculated by the score calculation unit 33 using correction values based on reviewer evaluation tendencies managed in the correction value DB 44. For example, if reviewer A also evaluates harshly in other review information, the correction value is "1.2" times, "+0.5", etc., so the score correction unit 34 The score for each category of review information is multiplied by 1.2 or +0.5. As a result, if the score of the category "cooking/taste" calculated by the score calculating section 33 is "4", the score correcting section 34 multiplies it by "1.2" to correct it to "4.8". Further, when the score of the category "service" calculated by the score calculation unit 33 is "4", the score correction unit 34 multiplies the score by "1.2" to correct it to "4.8". Note that the processing by the score correction unit 34 may be omitted.
　スコア平均部３５は、レビュイー毎に、複数のレビュー情報における同じカテゴリ毎の（補正後）スコアの平均値を算出する。例えば、第１の評価対象のレビュー情報における「料理・味」のカテゴリの補正後のスコアが「4」で、第２の評価対象のレビュー情報における「料理・味」のカテゴリの補正後のスコアが「4.2」の場合、スコア平均部３５は、「料理・味」のカテゴリの平均値として「4.1」を算出する。このようにして、スコア平均部３５は、店舗、商品、又はサービスを提供する店舗等のレビュイー毎に、各カテゴリのスコアの平均値を算出する。 The score averaging unit 35 calculates, for each reviewee, the average value of scores (after correction) for each of the same categories in a plurality of pieces of review information. For example, if the corrected score of the "Cooking/Taste" category in the review information of the first evaluation target is "4", the corrected score of the "Cooking/Taste" category in the review information of the second evaluation target is "4.2", the score averaging unit 35 calculates "4.1" as the average value of the "cooking/taste" category. In this way, the score averaging unit 35 calculates the average value of the scores of each category for each reviewee of a store, a product, a store that provides a service, or the like.

　Ｓ１０４：スコア平均部３５は、レビュイー毎に、各レビュー情報におけるカテゴリ毎の（補正後の）スコアの平均値を算出することでレビュー情報を加工し、加工後のレビュー情報を加工レビューＤＢ４５に記憶して管理する。 S104: The score averaging unit 35 processes the review information by calculating the average score (after correction) for each category in each review information for each reviewee, and stores the processed review information in the processed review DB 45. and manage it.
　以上により、図５に示すＳ１６の処理の説明を終了する。 This concludes the explanation of the process of S16 shown in FIG. 5.
　Ｓ１７：サービス提供装置３の送受信部３１は、ユーザ端末７からの要求に応じて、加工レビューＤＢ４５で管理されている、カテゴリ毎のスコアの平均値を含んだ加工後のレビュー情報を送信する。ユーザ端末７では、送受信部７１が加工後のレビュー情報を取得し、表示制御部７４がディスプレイ７０７上に、加工後のレビュー情報に基づいて、図７に示すようなレビュー画面１１０を表示させる。図７は、加工処理後のレビュー画面を示す図である。 S17: In response to a request from the user terminal 7, the transmitting/receiving unit 31 of the service providing device 3 transmits the processed review information that is managed in the processed review DB 45 and includes the average score for each category. In the user terminal 7, the transmitting/receiving unit 71 acquires the processed review information, and the display control unit 74 displays a review screen 110 as shown in FIG. 7 on the display 707 based on the processed review information. FIG. 7 is a diagram showing a review screen after processing.
　ここで、図７を用いて、レビュー画面１１０を説明する。図７に示すように、レビュー画面１１０には、個人評価ランク及び総合評価ランク（ここでは共に「4.8」）を表した評価欄１１１、カテゴリ毎の評価ランクを表したカテゴリ別評価欄１１２、レビュワーが入力したレビュー情報を表示したカスタマレビュー欄１１３等が含まれている（表示されている）。なお、スコアはランクとして表される。なお、評価欄１１１の上部には、レビュワー個人の評価ランクが示され、評価欄１１１の下部には、サービス提供装置３が算出したレビュイー毎の評価ランクが示されている。カテゴリ別評価欄１１２の各カテゴリのスコアは、スコア平均部３５によって算出された値である。 Here, the review screen 110 will be explained using FIG. 7. As shown in FIG. 7, the review screen 110 includes an evaluation column 111 showing the individual evaluation rank and the overall evaluation rank (here both "4.8"), a category evaluation column 112 showing the evaluation rank for each category, and a reviewer It includes (is displayed) a customer review field 113 that displays review information input by the user. Note that the score is expressed as a rank. Note that the upper part of the evaluation column 111 shows the evaluation rank of the individual reviewer, and the lower part of the evaluation column 111 shows the evaluation rank of each reviewee calculated by the service providing device 3. The score for each category in the category evaluation column 112 is a value calculated by the score averaging section 35.

For example, if it is "(trust) information" for supporting the provision of a service with a more reliable evaluation, it does not have to be the processed review information that is the basis of the review screen 110 shown in FIG. 7.
　以上により、図５に示す処理が終了する。 With the above, the process shown in FIG. 5 ends.
　〔実施形態の効果〕
　以上説明したように本実施形態によれば、複数のレビューサイトが複数存在しても、サービス提供装置３は、レビュー情報内の各トピックを予め定めたカテゴリに分け、カテゴリ毎のスコアを算出するため、統一的な評価形式となる。そのため、ユーザがレビュー内容を握し易いようにすることができる。またこれにより、評価ソースの多様性による、より信頼性の高い評価の実施が期待される。 [Effects of embodiment]
As explained above, according to the present embodiment, even if there are multiple review sites, the service providing device 3 divides each topic in the review information into predetermined categories and calculates a score for each category. Therefore, it becomes a unified evaluation format. Therefore, it is possible to make it easier for the user to understand the review contents. This is also expected to lead to more reliable evaluations due to the diversity of evaluation sources.
　また、スコア補正部３４が、レビュワーの評価傾向に基づく補正値を用いて、スコア算出部３３によって算出された同じレビュワーによるレビュー情報におけるカテゴリ毎のスコアを補正するため、偏った評価をするレビュワーがいても、ユーザが惑わされないようにすることができる。 In addition, since the score correction unit 34 corrects the score for each category in the review information by the same reviewer calculated by the score calculation unit 33 using correction values based on the reviewer's evaluation tendency, reviewers who give biased evaluations It is possible to prevent the user from being confused even if the
