- a column 415 describes information representing the business content when each causal relationship is recorded in the system.
- information on the index type and its value that is the reason for determining that there is a causal relationship is described.
- the causal model that “housewives are easy to purchase healthy products” is quantitatively expressed as “the ratio of the purchase rate is 2.6 ⁇ 0.3 between the consumer group other than housewives and the consumer group of housewives. Means "double". This value may be a value calculated based on input information, or an expected value manually input.
- a causal model may be configured based not only on the purchase ratio (the ratio of purchase ratio among consumer groups) but also on other indicators such as the purchase ratio at the time of visit (probability of purchasing when visiting the store). A plurality of indicators that can be the basis for this may be recorded.
- a causal relationship hypothesis is manually accepted, but the causal relationship may be automatically estimated using data and conceptual information defined in the past. For example, a purchase rate between concepts may be calculated, and based on the calculated value, it may be estimated that “a causal relationship exists between a consumer concept with a high purchase rate and a product concept”. Also, in order to build a more accurate causal model without recording the input hypothesis as a causal relationship, the causal relationship between the input concept and actual data is evaluated, and the concept and actual data are The update of the association and the update of the causal relationship may be performed.

- the causal relationship estimation / concept update unit 111 acquires a product purchase price vector of each customer from the POS data 132 with personal ID.
- the product purchase value vector of each customer a vector expressing 1/0 of the customer's purchase experience with respect to each product can be considered.
- the vector regarding the number of purchases, the purchase ratio, etc. may be used.
- the causal relationship estimation / concept update unit 111 extracts consumers that are not linked to the consumer concept corresponding to each product node, and further calculates the average purchase value of the extracted consumer group. Calculate the standard purchase price of the product.
- the reference purchase value of the product may be other than the calculation result as described above. If a general purchase price for a certain product is obtained from conventional knowledge, it may be adopted.
- the causal relationship estimation / concept update unit 111 calculates the average value of the consumer's purchase price for all products for the consumer group associated with the consumer concept.
- the causal relationship estimation / concept update unit 111 compares the reference purchase price of each product with the average value of the purchase values of the consumers of the corresponding consumer group, and calculates the product purchase degree. For example, the ratio of the average value of the consumer's purchase value to the reference purchase value may be calculated, and this may be used as the degree of product purchase, or statistics between the reference purchase value population and the average purchase value population And the probability that they are not the same may be calculated.
- step S ⁇ b> 506 the causal relationship estimation / concept update unit 111 extracts an appealing product as an appealing product that is easy to purchase for a corresponding consumer group for a product with a high degree of product purchase. For example, it may be difficult to purchase a product with a low product purchase degree, and a non-appealing product may be similarly defined.
- three items of “easy to purchase”, “average”, and “difficult to purchase” are set, the attribution probability to each item is calculated, and the relationship between the consumer concept and the product is expressed as a continuous value vector. It may be expressed.
- step S507 the causal relationship estimation / concept update unit 111 sets the ratio of the appealing product to a certain consumer concept in the commodity group corresponding to each commodity concept as the appeal degree between the consumer concept and the commodity concept. calculate.
- step S507 can be said to be a step of estimating the degree of causal relationship based on the data between the consumer concept and the product concept when the product is classified by whether or not it is an appealing product (1/0).
- step S508 the causal relationship estimation / concept update unit 111 compares the input information of the causal relationship between the consumer concept and the product concept with the appeal level between the focused consumer concept and the product attribute, and the difference To extract.
- the causal relationship estimation / concept update unit 111 updates (addition / deletion) between the focused consumer concept and the product concept, or the product concept and the product, depending on the size of the extracted difference. Extract abstracts of abstract relations between groups.
- a uniform threshold may be set for the difference, and if a causal relationship exists between the consumer concept of interest and a plurality of product concepts, data and input information on the causal relationship with other product concepts
- a threshold value for whether or not to update may be determined based on the difference between the two.
- step S510 the causal relationship estimation / concept update unit 111 displays an update plan on the screen and accepts an input of an update instruction from a person in charge of business. However, the execution of this step may be skipped and the update may be performed automatically without accepting input from the person in charge of business.
- step S511 the causal relationship estimation / concept update unit 111 updates (1) the causal relationship between the consumer concept and the product concept, and (2) the correspondence between the product and the product group, based on the update instruction information. Then, a consumer group for the consumer concept according to the new causal relationship structure is extracted. That is, by the process shown in FIG. 5, it is possible to estimate (1) a causal relationship appropriately reflecting data and (2) a correspondence between a concept and data.

Since each consumer's behavior is affected by multiple causal models at the same time, it is necessary to link these multiple causal models and perform comprehensive impact predictions when predicting the effects of actual measures. is there.
- the abstract relationship between concepts is estimated based on the degree of duplication of data sets constituting each concept, and cooperation between causal models on actual data is realized.
- FIG. 6 shows an image of an abstract relationship between a plurality of concepts on the consumer space 604.
- the abstract relationship between concepts is a relationship that exists only between concepts of the same data type because it is estimated based on the degree of duplication of data sets.
- some of the consumers belonging to “Consumer Concept A” 602 belong to “Consumer Concept B” 603, while all of the consumers belonging to “Consumer Concept B” belong to “Consumer Concept A”.
- FIG. 7 shows the abstract relationship estimation processing procedure.
- FIG. 7 shows a procedure for accepting concept type information (for example, a concept related to a consumer) to be estimated in advance and estimating an abstract relationship between concepts related to the type.
- concept type information for example, a concept related to a consumer
- the abstract relationship estimation unit 112 receives input of concept type information for estimating an abstract relationship, and extracts a list M of all concepts of the same type.
- the abstract relationship estimation unit 112 estimates and records an abstract relationship with each concept in the concept list M for each concept in the concept list M.
- step S702 the abstract relationship estimation unit 112 extracts data belonging to the m1th concept m1 for each concept in the concept list M from the concept assignment result data 114.
- step S703 the abstract relationship estimation unit 112 extracts data belonging to the m2th concept m2 in the concept list M from the concept assignment result data 114.
- step 704 the abstract relationship estimation unit 112 calculates the number of data common to the concepts m1 and m2 (the number of common data), and calculates the recall rate s and the relevance rate t of the concept m1 based on these numbers. .
- the recall rate s and the relevance rate t are examples of values indicating a “ratio where a certain concept is tied to another concept”.
- the precision t is the ratio of the number of common data in the number of data of one concept (for example, concept m1)
- the recall ratio s is the ratio of the number of common data in the number of data of the other concept (for example, concept m2). is there.
- step S705 the abstract relationship estimation unit 112 determines whether the relationship between the concept m1 and the concept m2 is higher / lower / equivalent / irrelevant based on the precision t and the threshold ⁇ 0 and the recall s and the threshold ⁇ 1. It is determined whether it is.
- the threshold value ⁇ 0 and the threshold value ⁇ 1 may be arbitrarily determined. For example, if both the precision t and the recall s exceed the threshold, it is determined to be “equivalent”, and if only the precision t exceeds the threshold, the concept m1 is determined to be “higher” and reproduced. When only the rate s exceeds the threshold, it is determined that the concept m1 is “lower”.
- step S706 the abstract relationship estimation unit 112 inputs the recall ratio s between the concepts m1 and m2 and the higher / lower / equivalent / irrelevant abstract relationship information to the abstract relationship matrix.
- the processing procedure shown in FIG. 7 estimates the abstract relationship between concepts by brute force. However, this method may have a large amount of calculation when the number of concepts is large. On the other hand, if the following rules are used, the abstract relation can be estimated without performing brute force, and the calculation time can be reduced. For example, if the concept m2 is a subordinate concept of the concept m1, the rule that the subordinate concept of the concept m2 is considered to be a subordinate concept of the concept m1, and if the concept m2 is a superordinate concept of the concept m1, the superordinate concept of the concept m2 is a concept. A rule that is considered to be a superordinate concept of m1 is used.

- the analysis screen 901 will be described later.
- the “add measure parameter” button 815 is a button for changing the parameter itself controlled by the measure. For example, conditions such as coupon design and presence / absence of photo display can be added to the coupon distribution conditions. For example, in order to distribute coupons for young people, when additional services such as distributing stamps for message applications are implemented, or when the distribution coupon design is devised, parameters can be added as variable items in the measures. Therefore, it is possible to construct a consumer behavior model that takes into account the effects of these new parameters. In the case of a new parameter for which there is no policy implementation history in the past, data is insufficient, and therefore a certain amount of data accumulation period is required to perform a quantitative impact assessment. Even during a period in which the quantitative value cannot be calculated, displaying a parameter on the measure evaluation screen that can explain the error factor between the prediction and the actual measurement may help qualitative business personnel.

Abstract
Description
本実施例では、業務担当者から入力された定性的な知見に基づいて実業務履歴データ(実購買履歴など)から施策効果予測のための因果モデルを生成する機能と、生成した因果モデルに対して任意の概念名称で表現された因子の追加を受け付ける機能と、業務担当者が想定する様々な因子間の関係性を実行動履歴データに基づいて評価する機能を有する業務計画/効果検証支援システム(以下、「支援システム」又は「システム」という。)について説明する。
図1に、実施例1に係る支援システム1の構成を示す。支援システム1は、業務担当者が操作する端末100と中央サーバ101で構成される。端末100及び中央サーバ101はコンピュータ(CPU、RAM、ROM、ハードディスク装置など)を基本構成とする。図1では、中央サーバ101に対して入出力される情報を端末100に関連付けて表している。情報の入出力には操作画面が用いられる。操作画面には、概念定義画面、因果関係仮説生成画面、抽象関係仮説生成画面、分析画面、施策パラメータ設計画面、施策評価画面などがある。支援システム1は、これらの操作画面を通じ、業務担当者の業務(例えば顧客ニーズの把握/施策パラメータの検討のための分析、施策立案、実施結果の評価/改善)を支援する。
(1-2-1)概念定義画面
図2に、概念設計初期情報102の受け付けに用いられる概念定義画面201の一例を示す。概念定義画面201は、概念定義部110に対する入力情報の受け付け画面である。業務担当者の考える定性的な知見をデータ上のモデルとして表現するためには、業務担当者の考える概念が実業務履歴データの何を反映する概念であるかを明らかにする必要がある。本実施例の場合、任意の名称の概念と実業務履歴データ上のデータとの対応付けによって定義する。実際の対応付けは、概念定義部110が実行する。
図4に、概念間の因果関係仮説情報104の受け付けに用いられる因果関係仮説入力画面401の一例を示す。概念間の因果関係仮説情報104とは、消費者の消費行動に影響を与える因子と影響種別に関する情報である。因果関係仮説入力画面401では、任意の消費者に関する概念と、その概念に属する消費者集団に影響を与え得る任意の因子間の関係を入力することができる。因果関係は、因果関係仮説入力画面401を通じて業務担当者が入力してもよいが、画面定義画面201(図2)で定義された「消費者」、「商品」、「地域」、「時間帯」等の概念から推定された因果関係を入力してもよい。
図8に、施策パラメータ設計画面801の例を示す。施策パラメータ設計画面801は、提供予定のサービス施策の具体的なパラメータを入力する際に使用される。施策名802には計画中の施策の内容を表す名称が入力される。図8では、「多摩地区振興クーポン配信」サービスが入力されている。施策名802の下には、関連する基本条件の入力欄が配置される。時刻803には施策期間が入力され、消費者804には施策対象消費者が入力され、商品805には施策の対象商品が入力され、地域806には地域が入力される。これら条件は施策内容によっては指定ができない場合がある。例えば店頭販売であれば、対象消費者は施策実施時の来店者であり、予め設定することはできない。
図9に、あるパラメータの内容に紐づいている複数の概念に関するモデル群(因果関係モデル、抽象関係モデル)の抽出、確認、活用したモデルの抽出等に使用する分析画面901の例を示す。分析画面901は、様々なデータソースに着眼した分析結果の確認を可能とすることで顧客の消費行動モデルを深く理解し、適切な施策パラメータを検討するための画面である。
図12に、施策評価画面1201の一例を示す。この画面は、モデル評価・更新器120が作成して表示する。「施策情報」の表示部1201には、施策パラメータの内容情報が表示される。「施策実施結果」の表示部1202には、施策のKPIの目標と実際の実施結果に関する情報が表示される。これらの情報により、業務担当者は、施策効果を確認することができる。「関連消費者モデル一覧」の表示部1203には、対応する施策と紐づく因果関係・抽象関係のモデルの一覧が表示される。
上述したように、本実施例の支援システムを用いれば、業務担当者の定性的な知見・概念を業務履歴データと紐づけた消費者の因果関係・抽象関係のモデル群を構築することができ、複数のデータ・観点での分析を統合した施策パラメータの設計や消費者行動傾向の観点から施策実施結果評価を実現することができる。また、本実施例の支援システムによれば、個人毎の購買履歴等の複数の業務履歴データを入力として、業務履歴のデータ項目に関する任意の概念について、概念とその概念に属するデータの対応関係、異なるデータ項目に関する複数概念間の因果関係の推定、同一データ項目に関する複数概念間の上下/同一/無関係を推定することが可能となる。その結果、業務担当者は、自身の定性的な経験・勘を含む様々な定性的な業務知見に基づき、業務実施結果とその因子に関する自由度が高く実データ傾向に対して精緻な因果関係モデルを生成し、生成された因果関係に基づき効率的に効果的な業務計画を検討できる。
本発明は、上述した実施例に限定されるものでなく、様々な変形例を含んでいる。例えば、上述した実施例は、本発明を分かりやすく説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備える必要はない。また、ある実施例の一部を他の実施例の構成に置き換えることができる。また、ある実施例の構成に他の実施例の構成を加えることもできる。また、各実施例の構成の一部について、他の実施例の構成の一部を追加、削除又は置換することもできる。
