  Hereinafter, embodiments of a business card information registration apparatus and the like will be described with reference to the drawings. In addition, since the component which attached the same code in embodiment performs the same operation | movement, description for the second time may be abbreviate | omitted.

  FIG. 1 is a block diagram of an information system in the present embodiment. This information system comprises a business card information registration device 1, one or more user terminals 2, and one or more counterpart terminals 3. The business card information registration device 1 is communicably connected to each of the one or more user terminals 2 and the one or more counterpart terminals 3 via, for example, a network such as a LAN or the Internet, a wireless or wired communication line, or the like.

  The business card information registration device 1 is, for example, a server of a company operating the information system, but may be a cloud server, regardless of its type or location.

  The user terminal 2 and the counterpart terminal 3 are terminals of a registrant who registers a business card using the present information system. The registrant is a user or a partner. The user is a person who has passed a business card, and the other person is a person who has received a business card. The user operates the user terminal 2 to register his business card, and the partner operates the other terminal 3 to register the business card received from the user.

  In the present embodiment, for convenience, the registrant registering his business card is referred to as a user, and the person registering the business card received from the user is referred to as a partner, but the partner also registers his business card, and the user It is preferable to register the name card received from the other party. In such a case, in the following description, the relationship between the user and the other party is reversed. Moreover, the registration of the business card of oneself does not necessarily need to be performed, for example, when the business card of the employee of the same company as oneself has been registered, or when registered by the other party or another party first.

  The terminal is, for example, a PC, but may be a portable terminal or the like, regardless of its type or location. It is preferable that the PC is communicably connected to, for example, a scanner for capturing a business card image or a multifunction peripheral having a scanner function via a LAN. Moreover, although a portable terminal is a tablet terminal, a smart phone, a mobile telephone etc., for example, the kind is not ask | required. Note that the mobile terminal has, for example, a camera function, and can capture a business card image. Based on the above, the user terminal 2 is a terminal of the user, and the other terminal 3 is a terminal of the other party who has received a name card from the user. It is needless to say that the business card passed by the user to the other party is a business card (hereinafter referred to as a "user's business card") on which information such as a user identifier for identifying the user is written.

  A business card consists of two or more items. The item may be an attribute name of various information described on the business card. The items are, for example, a user identifier, a telephone number, an address, etc., but the type is not limited.

  The user identifier is information for identifying a user. The user identifier is, for example, a name, but may be considered to include a post name, a department name, and the like attached to the name. Also, for example, an e-mail address, a mobile phone number, a member ID or the like may be considered as a kind of user identifier. As described above, the user identifier may be of any type as long as the information can identify the user. However, the user identifier written on the business card is usually information such as the name or the name and the job title attached thereto, and the e-mail address can be considered as an item different from the user identifier.

  The company name is the name of an organization (including a company, a group, a personal store, etc.) to which the user belongs. The telephone number is usually a telephone number of a company or the like, and the address is also an address of a company or the like.

  In addition, the other party who receives the business card from the user also usually passes his or her business card to the user. In the present embodiment, one of the two business cards exchanged between the two in this way is focused on one of the business cards, and the user who passed the business card is called the user, and the one who received the business card is called the other party. Focusing on the other business card among the two exchanged business cards, the relationship between the two is reversed. Therefore, the user may be replaced with the other party and the other party may be replaced with the user. Alternatively, the user and the other party may be distinguished, for example, by being called a first user, a second user, and the like.

  The business card information registration device 1 includes a storage unit 11, a reception unit 12, a processing unit 13, and a transmission unit 14. The storage unit 11 includes a business card information storage unit 111 and an exchange business card information storage unit 112.

  The storage unit 11 constituting the business card information registration device 1 can store various types of information. The various types of information are, for example, business card information, exchange business card information, and the like. Other information will be explained as appropriate.

  The business card information storage unit 111 stores one or more business card information. Business card information is information on a business card. A business card is a user's business card. The business card information includes, for example, a business card image and two or more character strings. A string is a set of one or more characters. A character is a character represented by a character code, and may be considered to include, for example, a symbol or a mark such as "〒" or "@". A business card image is an image of a business card. A character string is a character string of two or more items as described above which constitute a business card. The character string of each item is, for example, the character string "AA" corresponding to the item "user identifier", the character string "06 ..." corresponding to the item "telephone number", the character string corresponding to the item "address" For example, “〒 540 ...”.

  The business card information may have two or more partial business card images instead of or in addition to the business card image. A partial business card image is an image of a part of a business card. The partial business card image is, for example, an image of two or more items constituting a business card. Also, the business card information usually has a user identifier.

  The business card information may have, for example, a user identifier, a business card image, and two or more pieces of partial business card information. Partial business card information is information on a part of a business card. The partial business card information includes, for example, a partial business card image, a character string, and an item identifier.

  The business card information may have, for example, a feature vector instead of or in addition to the business card image or the partial business card image. A feature vector is a set of one or more feature quantities of a business card image or a partial business card image. The feature amount is, for example, a feature related to the distribution of color or brightness of an image. This type of feature may be an average value of pixel values of each block or a two-dimensional distribution of the average value when an image such as a business card image is divided into two or more blocks.

  Alternatively, the feature amount may be an amount indicating a graphic feature of a business card image or a partial business card image. This type of characteristic is, for example, the shape of an outline obtained by binarizing an image such as a business card image, or the shape of an area surrounded by such an outline, or the number or size of such areas. is there. This type of feature amount may be, for example, a numerical value corresponding to the number of characters of the characters written on the business card, the font, the number of points, and the like. However, the feature amount may be any amount as long as it indicates a feature such as a name card image.

  The business card information stored in the business card information storage unit 111 is usually information registered by the user himself. However, for example, a person in charge at a company of the user may register business card information of one or more employees including the user. The business card information may be registered by anyone if it is a person other than the other party.

  The exchange business card information storage unit 112 stores one or more exchange business card information. Similar to business card information, exchange business card information is information related to the business card of the user, but unlike business card information, it is information registered by the other party who received the business card from the user. The exchange business card information is usually information corresponding to one business card information among one or more business card information stored in the business card information storage unit 111. However, the business card information storage unit 111 may not have business card information corresponding to the exchange business card information.

  The exchange business card information usually differs in part of its configuration from the business card information. Moreover, in exchange business card information, even if it is a part common to business card information, the data format may differ. The common part is, for example, a business card image. The business card image of the exchange business card information is, for example, a bitmap such as GIF or JPEG, while the business card image of the business card information may be, for example, a feature vector. However, the exchange business card information may have the same configuration as the business card information, and the data structure of each component may be the same.

  The exchange business card information includes a business card image. The exchange business card information may include a partner identifier and a business card image. Alternatively, the exchange business card information may include, for example, one or more of a user identifier or a partner identifier, and a business card image. The user identifier included in the exchange business card information is an identifier of the user who has passed the business card, and the business card image is also an image of the user's business card. Moreover, it is preferable that the exchange business card image has, for example, a character string of two or more items, and it is more preferable that the exchange business card image also have an item identifier corresponding to the character string of two or more items. .

  The exchange business card information storage unit 112 normally stores one or more exchange business card information as described above in association with the other party identifier. The other party identifier is information for identifying the other party. The other party identifier is, for example, a name as in the case of the user identifier, but may be a name, a post name, or the like, and any information that can identify the other party may be used. The exchange business card information of the exchange business card information storage unit 112 may be information which shares a part with the business card information of the business card information storage unit 111.

  The receiving unit 12 receives various types of information. The various types of information are, for example, exchange name information, user registration information, and the like. The receiving unit 12 also receives, for example, a partner identifier group output instruction described later, an exchange business card information group output instruction described later, and the like.

  The exchange business card information reception unit 121 receives exchange business card information. Although the exchange business card information reception unit 121 normally receives exchange business card information from the other party terminal 3, for example, it may be received from the user terminal 2. That is, the business card of the other party is also registered, and the user may register the business card exchange information related to the business card received from the other party. In such a case, the exchange business card information receiving unit 121 receives the business card of the other party from the user terminal 2 Receive exchange business card information about.

  The exchange business card information reception unit 121 normally receives exchange business card information in a pair with the other party identifier. Note that receiving in pairs also includes the case where the exchange business card information has a partner identifier. Also, the information received in the pair may be a partner terminal identifier described later, or may be a partner identifier that doubles as a partner terminal identifier.

  The user registration information receiving unit 122 receives user registration information. The user registration information is information for registering a user's business card. The user registration information includes a business card image. The user registration information may also include a user identifier. Furthermore, the user registration information may also include, for example, character strings of two or more items. However, since the user identifier and the character string of each item can be obtained from the business card image by character recognition such as OCR, it may not be included in the user registration information.

  The processing unit 13 performs various processes. The various processes include, for example, a character string acquisition unit 131, a division unit 1311, a character string acquisition unit 1312, an exchange business card information storage unit 132, a character recognition unit 133, an item identifier acquisition unit 134, a business card information storage unit 135, and the like. It is a process.

  The character string acquisition unit 131 uses the exchange business card information received by the exchange business card information reception unit 121 and the one or more business card information stored in the business card information storage unit 111, and the business card included in the received exchange business card information Gets a string of one or more items paired with the image.

  The character string acquisition unit 131 is, for example, a business card information storage unit 111 or an exchange business card information storage unit that is similar to a business card image similar to the business card image included in the exchange business card information received by the exchange business card information reception unit 121. The character string of one or more items to be paired with the business card image is acquired by searching from one or more of the 112. The predetermined condition is, for example, the similarity between all or part of the business card image of the received exchange business card information and all or part of the business card image of one or more of the stored business card information The condition regarding

  The condition relating to the similarity between such business card images is, for example, that the similarity is above the threshold or above the threshold, and that the similarity is above the threshold is identical (for example, the similarity is 100%) ) Also includes.

  Alternatively, the character string acquisition unit 131 is newly received unknown by performing machine learning using the exchange business card information received by the exchange business card information reception unit 121 and one or more pieces of stored business card information. The business card image or partial business card image similar to all or part of the business card image included in the exchange business card information is detected, and a character string of one or more items paired with the detected business card image or partial business card image is acquired It is also good.

  Specifically, the character string acquisition unit 131 divides, for example, a business card image included in the exchange business card information received by the exchange business card information reception unit 121 into one or more partial business card images, and from the one or more partial business card images Feature vectors may be obtained. At that time, the character string acquisition unit 131 learns the relation between the feature amount and the feature vector acquired from the business card image or one or more partial business card images, and uses the learning information which is the learning result. It is preferable to obtain a feature vector from an unknown business card image or the like. Specifically, the character string acquisition unit 131 can learn such a relationship using, for example, an algorithm of machine learning such as deep learning, SVM (support vector machine), decision tree, random forest, and the like. Then, the character string acquisition unit 131 searches the business card information storage unit 111 for a feature vector that is similar to the acquired feature vector so as to satisfy a predetermined condition, and the character of one or more items paired with the feature vector. You may get a column.

  The similar feature vector is, for example, a feature vector having a short distance to the obtained feature vector. Alternatively, the similar feature vector may be a feature vector whose direction is the same as or close to the acquired feature vector. The condition in the former case is a condition regarding the distance between two feature vectors, for example, the distance is smaller than or equal to the threshold. The condition in the latter case is a condition relating to an angle formed by two feature vectors, and for example, the angle is smaller than or equal to a threshold. However, the condition may include both a condition on distance and a condition on angle.

  The target of machine learning is not limited to the relationship between the feature amount such as a business card image and the feature vector obtained from the business card image and the like as described above. For example, the character recognition unit 133 described later can improve the character recognition accuracy by performing machine learning on the relationship between the feature vector acquired from the business card image or the like and the character string acquired from the feature vector. In addition, the item identifier acquisition unit 134 described later can improve the acquisition accuracy of the item identifier by performing machine learning on the relationship between the character string acquired from the feature vector and the item identifier acquired from the character string. .

  In addition, the character string acquisition unit 131 is also a character string of one or more items to be paired with the business card image of the business card information from the business card image of the user registration information received by the user registration information reception unit 122, for example. To get At that time, the character string acquisition unit 131 usually acquires the character string by performing character recognition on a business card image included in the received user registration information. However, the character string acquisition unit 131 is stored in, for example, a business card image included in the received user registration information and one or more business card information or exchange business card information storage unit 112 stored in the business card information storage unit 111. Such a character string may be acquired using one or more types of information among one or more exchange business card information.

  Note that the degree of similarity between business card images, the learning of the feature amount of the business card image, and the items concerning conditions, which are used when the character string acquisition unit 131 acquires a character string corresponding to a business card image, are character string acquisition means 1312 described later. The same applies to the degree of similarity between partial business card images, learning of feature quantities of partial business card images, and conditions used when acquiring a character string corresponding to a partial business card image.

  The dividing unit 1311 acquires two or more partial business card images from the business card image included in the exchange business card information received by the exchange business card information reception unit 121. More specifically, the dividing unit 1311 includes two or more parts corresponding to the two or more items described above, for example, one or more lines along a space between character strings and a business card image included in the received exchange business card information. To obtain a partial business card image from each of the two or more parts. Note that one or more lines are, for example, a set of one or more straight lines in the horizontal direction when the character string is written horizontally, and a set of one or more straight lines in the vertical direction when the character string is written vertically, It may be a combination of vertical and horizontal straight lines, or some or all of them may be curved.

  In addition, it is preferable that the dividing unit 1311 acquire two or more partial business card images also from the business card images included in the user registration information received by the user registration information reception unit 122.

  The character string acquisition unit 1312 searches the business card information storage unit 111 for a partial business card image similar to the two or more partial business card images acquired by the division unit 1311 so as to satisfy a predetermined condition, for example. Get a string to be paired.

  The predetermined condition is a condition regarding the similarity between the acquired partial business card image and, for example, two or more partial business card images stored. The conditions relating to the degree of similarity between such partial business card images are also, for example, that the degree of similarity is above the threshold or above the threshold, and that the degree of similarity is above the threshold includes the case where they match.

  The exchange business card information accumulation unit 132 associates the character string of one or more items acquired by the character string acquisition unit 131 with the exchange business card information and stores it in association with the other party identifier received in pairs. Specifically, the exchange business card information storage unit 132 uses the exchange business card information received by the exchange business card information reception unit 121 and the one or more business card information stored in the business card information storage unit 111, and the character string acquisition unit 131 The acquired character strings of one or more items are stored in association with the other party identifier received in pairs with the exchange business card information.

  Alternatively, the exchange business card information storage unit 132 may store the character string acquired by the character recognition unit 133 described later in association with the exchange business card information and the other party identifier received in pairs.

  In addition, the exchange business card information storage unit 132 is a character of one or more items acquired by the character string acquisition unit 131 or acquired by the character recognition unit 133 in association with the item identifier acquired by the item identifier acquisition unit 134 described later. Columns may be accumulated.

  Further, the exchange business card information storage unit 132 acquires an item identifier from the character string acquired by the character string acquisition unit 131 or the character recognition unit 133 from the two or more partial business card images acquired by the dividing unit 1311 The item identifier acquired by the unit 134 may be stored in association with the exchange business card information and the other party identifier received in pairs.

  Furthermore, the exchange business card information storage unit 132 may also store the business card image included in the exchange business card information in association with the other party identifier received in a pair with the exchange business card information.

  The storage destination of the character string may be the business card information storage unit 111 or the exchange business card information storage unit 112. A business card image may also be stored, and the storage destination may be the business card information storage unit 111 or the exchange business card information storage unit 112.

  The character recognition unit 133 performs character recognition processing on the business card image included in the exchange business card information received by the exchange business card information reception unit 121 or two or more partial business card images acquired therefrom, and performs one or more character strings. get.

  For example, when the character string acquisition unit 131 determines that there is no business card image similar to the business card image included in the exchange business card information received by the exchange business card information reception unit 121, the character recognition unit 133 fulfills a predetermined condition. Or, if the character string acquisition unit 1312 determines that there is no partial business card image similar to the two or more partial business card images acquired by the dividing unit 1311 so as to satisfy a predetermined condition, the business card image of the exchange business card information Alternatively, character recognition processing is performed on the partial business card image to acquire a character string.

  The character recognition unit 133 also performs character recognition on a business card image of the user registration information received by the user registration information reception unit 122 or on two or more partial business card images acquired by the dividing unit 1311 from the business card image. It is preferable to process and obtain two or more character strings.

  The item identifier acquiring unit 134 uses, for example, one or more character strings acquired by the character string acquiring unit 131 or the character recognizing unit 133 using correspondence information between a specific character string and an item identifier, and an item for each character string Get an identifier. The specific character string is, for example, “〒”, “TEL”, “corporation”, etc., but may be a surname such as “Suzuki” or “Ichiro”, as long as the item identifier can be specified. Anything is fine. The correspondence information is stored, for example, in the storage unit 11 in advance. Alternatively, the item identifier acquisition unit 134 may acquire, for example, an item identifier corresponding to a character string by machine learning.

  The item identifier is information for identifying two or more items constituting a business card. The item identifier may be, for example, an item name such as “name” or “telephone number”, or an ID (eg, item number) associated with the item name or the like, as long as the information can identify the item.

  The business card information storage unit 135 acquires the user identifier in response to the reception of the user registration information by the user registration information reception unit 122. Then, the business card information storage unit 135 constructs, for example, business card information having the acquired user identifier, the business card image included in the received user registration information, and the character string acquired or input from the business card image. It is stored in the business card information storage unit 111.

  Specifically, the business card information storage unit 135 may acquire the user identifier included in the user registration information in response to the reception of the user registration information.
