Description

  The present invention relates to a technical term replacement device that can replace technical terms with technical terms corresponding to the user's literacy level, an operation method thereof, and a computer program.

  In recent years, the term “ICT literacy” has been used as an acronym for each of the acronyms for the level of education related to technology (technology) related to information (information) and communication (technology).

  In recent years, with the explosive spread of the Internet, it is required to provide thorough support to customers whose ICT literacy level (called literacy level) is not high. To that end, it is necessary to respond to questions from customers in easy-to-understand technical terms and to explain technical terms in the manual in easy-to-understand technical terms. However, at present, technical terms are often used as they are, and there are many cases that customers cannot understand. Therefore, it is required to explain various devices in technical terms that are easy for customers to understand.

  Therefore, conventionally, a response evaluation apparatus has been invented that detects an audio feature amount from an audio signal issued by a customer and calculates a response score (Patent Document 1). Although the present invention has made it possible to evaluate responses based on the customer's voice, it has not yet reached the invention of an apparatus that provides technical terms that are easy to understand for customers.

  Also, in the voice response method, when a caller receives an incoming call by holding a response history including the result of past voice recognition success / failure, the number of responses, and the response format at the time of response for each caller. The voice response method is characterized in that the response history corresponding to the caller is searched and a response by voice recognition is performed when there is a continuous history of voice recognition more than a predetermined number of times ( Patent Document 2). However, it is limited to the case where voice recognition can be used, and does not describe a technique that can be used by an operator.

  Therefore, there is a system that can use technical data that has already been accumulated to simplify and simplify the technical terms and use the technical terms that are replaced according to the customer's literacy level. It has been demanded.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a schematic configuration of a technical term replacement device according to the present embodiment.
The technical term replacement device 1 replaces the technical term with a technical term corresponding to the literacy level, which is a technical term corresponding to a literacy level related to a user's technology that needs to be understood (the literacy level is used in the meaning of “education level” or the like). Device. The technical term replacement device 1 is used here by an operator who answers a telephone inquiry from a customer who purchased an electrical product or the like. When explaining the technical terms described in the manuals of electrical products to the customer, the operator replaces the technical terms with technical terms according to the customer's literacy level, thereby obtaining the customer's understanding. Thus, the user is here a customer.

  The technical term replacement device 1 is connected to a display device 2 and an input device 3 used by an operator. Here, the input device 3 is used as a general term for input devices including a mouse and a keyboard.

  The technical term replacement device 1 includes a literacy level corresponding technical term storage unit 11 in which one or more literacy levels are associated with predetermined keywords, and a literacy level corresponding technical term is associated with each literacy level, and a manual or the like. An operator makes a judgment based on a document file acquisition unit 12 that acquires a text file including technical terms from a storage device (not shown) provided outside or inside the technical term replacement device 1, and words spoken by the customer in conversation. The user literacy level, which is the customer's literacy level input to the input device 3, is acquired via the input device 3, and a technical term matching the keyword is searched from the sentence file, and the literacy level is supported. Corresponds to the keyword and matches the user literacy level from the technical term storage unit 11 A technical term replacement unit 14 that reads a literacy level-compatible technical term associated with the keyword and the literacy level, replaces the technical term with the literacy level-compatible technical term, and a text file after the replacement. A text file display unit 15 for displaying the information, and an information updating unit 16 for updating the information stored in the literacy level corresponding technical term storage unit 11 based on information input to the input device 3 by the operator.

FIG. 2 is a diagram illustrating an example of the configuration of the literacy level corresponding technical term storage unit 11.
In the literacy level technical term storage unit 11, for example, three types of literacy levels “3”, “2”, and “1” are associated with two keywords “line terminator” and “router”. ing.

  The literacy level “3” corresponds to a user who is familiar with the technology. The same applies to a later-described user literacy level “3” input by the operator. The literacy level “1” corresponds to a user who is not skilled in technology. The same applies to the user literacy level “1”. The literacy level “2” corresponds to a user who is not familiar with the technology but is not familiar with the technology. The same applies to the user literacy level “2”. The literacy level and the user literacy level may be two stages or four or more stages.

  The literacy level “3” associated with the keywords “line terminator” and “router” includes the literacy level technical term “line terminator” and the literacy level technical term “line terminator” Corresponds to the number of times used and the number of times the customer understood the literacy level compatible terminology “line terminator”. The literacy level “2” is associated with the literacy level-compatible technical term “router” and the usage count and understanding count for the literacy level-compatible technical term “router”. One of the literacy levels “1” is associated with the number of times of use and understanding of the literacy level technical term “white or black box” and the literacy level technical term “white or black box”. Other literacy level “1” is also associated with other literacy level technical terms, the number of uses, and the number of understandings.

  In addition, the literacy level-compatible technical term storage unit 11 corresponds to, for example, two keywords “power cord” and “AC adapter” and corresponds to three types of literacy levels “3”, “2”, and “1”. It is attached. The literacy level “3” is associated with the technical term “AC adapter” corresponding to the literacy level, and the number of uses and understanding thereof. The literacy level “2” is associated with the literacy level technical term “power cord”, and the number of uses and understanding thereof. One of the literacy levels “1” is associated with the technical term corresponding to the literacy level “a black box has something like a string”, and the number of uses and understanding thereof. Other literacy level “1” is also associated with other literacy level technical terms, the number of uses, and the number of understandings.

  In addition, the literacy level-compatible technical term storage unit 11 stores other keywords, one or more literacy levels are associated with each keyword, and each literacy level has a literacy level-compatible technical term, the number of uses, and the number of understandings. It is associated.

(Operation of technical term replacement device 1)
Next, the operation of the technical term replacement device 1 will be described.
For example, the operator determines whether the user literacy level, which is the customer's literacy level, is the user literacy level “3”, “2”, or “1” based on the age of the customer, the years of Internet use, and the like. The user literacy level is input to the input device 3.

  The user literacy level acquisition unit 13 acquires the user literacy level via the input device 3 and transmits it to the technical term replacement unit 14.

  On the other hand, the document file acquisition unit 12 acquires a text file such as a manual of the electrical product purchased by the customer and transmits it to the technical term replacement unit 14.

FIG. 3 is a flowchart showing an operation flow of the technical term replacement unit 14.
When the technical term replacement unit 14 receives a user literacy level (hereinafter referred to as a user literacy level UL) and a text file, first, for each keyword in the literacy level compatible technical term storage unit 11, a technology that matches the keyword from the text file. A term is searched. Prior to this, it is determined whether or not there is an unsearched keyword (S1).

  If there is an unsearched keyword (S1: YES), the technical term replacement unit 14 stores a technical term (hereinafter referred to as technical term w) that matches the keyword k for each one (hereinafter referred to as keyword k) as a text file. It is determined whether or not (S3).

  If there is one or more technical terms w (S3: YES), the technical term replacement unit 14 searches the literacy level corresponding technical term storage unit 11 for a literacy level that corresponds to the keyword k and matches the user literacy level UL. (S5).

  Next, the technical term replacement unit 14 reads all the technical terms corresponding to the keyword k and the relevant literacy level (S7), and reads them at the position of the technical term w instead of each technical term w. All the technical terms corresponding to the literacy level are written (replaces the technical term w) (S9).

  If there is no technical term w (S3: NO) or after the replacement in step S9, the technical term replacement unit 14 returns the control to step S1 and searches for all keywords (S1: NO), and ends the process. .

  When the process of FIG. 3 is finished, the text file display unit 15 displays the text file after replacement on the display device 2.

FIG. 4 is a diagram illustrating a display example of a text file.
A text file M is displayed on the display device 2 and, for example, a literacy level corresponding technical term “white or black box” to “a wing-like one” replaced by the same technical term (for example, “line termination device”) "Is marked" is highlighted. In addition, an input area 100 for inputting a new literacy level compatible technical term for the technical term is displayed.

  For example, the operator determines whether or not the customer has understood the technical term corresponding to the literacy level “white or black box” by talking with the customer using the technical term “white or black box” corresponding to the literacy level.

  Next, when the operator positions the mouse pointer on the literacy level-compatible technical term “white or black box”, a determination result input screen 101 is displayed.

  When the operator aligns the mouse pointer while viewing the input screen 101 and inputs a determination result to the input device 3 by a click operation or the like, the information update unit 16 transmits the literacy level compatible technology via the input device 3. Acquire the term “white or black box” and the judgment result. Moreover, the information update part 16 acquires the keyword k in description of FIG. For example, by associating the keyword k with the positional information of the technical term “white or black box” in the text file, the information update unit 16 can acquire the keyword k even after the replacement. .

  For another literacy level technical term, if the operator performs the same operation as in the case of the literacy level technical term “white or black box”, the information updating unit 16 determines another literacy level technical term, Get the result and keyword k.

  On the other hand, for example, the operator inputs another expression that can be understood by the customer or another expression that cannot be understood by the operator even if the operator comes up with the idea and explains it to the customer as a new literacy level technical term. When a key is input to the device 3, new literacy level technical terms are displayed in the input area 100. Also for this literacy level compatible technical term, the information updating unit 16 acquires the literacy level compatible technical term, the determination result, and the keyword k. The keyword k is the same as the keyword k acquired for the literacy level-compatible technical term “white or black box” or the like, so that the information update unit 16 is a keyword for a new literacy level-compatible technical term. This (keyword k) can be acquired.

  That is, the information update unit 16 acquires one or more pieces of information (hereinafter referred to as operation information) including the technical terms corresponding to the literacy level, the determination result, and the keyword k.

  FIG. 5 is a flowchart showing a flow of operations performed by the information updating unit 16 based on each operation information.

  The information updating unit 16 searches the literacy level-compatible technical term storage unit 11 for the same keyword (hereinafter referred to as keyword K) as the keyword k in the operation information (S11), and the keyword K via any literacy level. It is determined whether there is the same literacy level corresponding technical term in the operation information (hereinafter referred to as the literacy level corresponding technical term W) among the associated literacy level corresponding technical terms (S13).

  If it is determined YES in step S13, the information updating unit 16 adds 1 to the number of uses associated with the literacy level corresponding technical term W and the keyword K (S15). Hereinafter, the usage count after the addition is referred to as usage count U.

  Next, the information update unit 16 determines whether or not the determination result in the operation information indicates that the customer understands (S17).

  If it is determined YES in step S17, the information updating unit 16 adds 1 to the number of times of understanding associated with the literacy level corresponding technical term W and the keyword K (S19). Hereinafter, the number of understandings after the addition or the number of understandings determined as NO in step S17 and not added are referred to as the number of understandings A.

  If it is determined NO in step S17, or if the process of step S19 is completed, the information updating unit 16 divides the number of understandings A by the number of times of use U (S21), and the division result value (hereinafter, understanding level). R) is determined to be 0.1 or less (S23).

  If the understanding level R is equal to or less than the predetermined value “0.1” (S23: YES), the information update unit 16 determines that the technical term W for literacy level is a difficult word that can only be understood by a user with a high literacy level. Therefore, if the literacy level (hereinafter referred to as literacy level L) associated with the literacy level technical term W and the keyword K is “1” or “2” or less, 1 is added to the literacy level L (S31). : YES, S31), the process ends. If the literacy level L is “3” (S31: NO), the process ends.

  If the understanding level R is greater than “0.1” (S23: NO), the information updating unit 16 determines whether the understanding level R is equal to or greater than a predetermined value “0.9” (S29).

  If the understanding level R is "0.9" or higher (S29: YES), the information update unit 16 means that the literacy level-compatible technical term W is an easy word that can be understood by a user with a low literacy level. In the case of “2” or “3”, 1 is subtracted from the literacy level L (S25: YES, S27), the process is terminated, and if the literacy level L is “1” (S25: NO), the process is terminated.

  If the understanding level R is less than 0.9 (S29: NO), the information update unit 16 ends the process.

  On the other hand, if it is determined NO in step S13, the information update unit 16 determines whether or not the determination result in the operation information indicates that the customer understands (S41).

  If it is determined YES in step S41, the information updating unit 16 associates the keyword K with the literacy level “3”, and the same word as the literacy level corresponding technical term in the operation information is associated with the literacy level “3”. Corresponding as a literacy level compatible technical term (S43), the process ends.

  If it is determined NO in step S41, the information updating unit 16 associates the literacy level “1” with the keyword K, and the same word as the literacy level corresponding technical term in the operation information is associated with the literacy level “1”. Corresponding as a literacy level compatible technical term (S45), the process ends.

  In this way, in this embodiment, technical terms related to various devices can be explained in an easy-to-understand manner even for customers who do not have a high user literacy level, and even technical operators who are unfamiliar with reception can easily explain technical terms. The customer can easily understand the contents of the response. As a result, it is possible to provide a reception with high customer satisfaction.

  That is, in the technical term replacement device 1 according to the present embodiment, one or more literacy levels are associated with a predetermined keyword, and the literacy level corresponding technical term is stored in correspondence with each literacy level. A storage unit 11, a document file acquisition unit 12 that acquires a text file including technical terms, a user literacy level acquisition unit 13 that acquires a user literacy level that is a user literacy level that requires understanding of technical terms, and a text file The technical term w that matches the keyword k is searched from (S3), the literacy level corresponding to the keyword k and the literacy level that matches the user literacy level is searched from the literacy level corresponding technical term storage unit 11 (S5), and the keyword k And read literacy level technical terms associated with literacy levels (S7) and replacing the technical term w with the technical term corresponding to the literacy level (S9), the technical term w is replaced with the technical term corresponding to the user literacy level by providing the technical term replacement unit. The term w can be understood in terms of literacy level compatible technical terms corresponding to the user's literacy level.

  In addition, the number of times the literacy level corresponding technical term is used by the user in association with each literacy level corresponding technical term in the literacy level corresponding technical term storage unit 11 and the number of times the user understands the literacy level corresponding technical term. And the technical term replacement device 1 acquires a determination result indicating whether or not the user has understood the replaced technical term corresponding to the literacy level, and uses the determination result and the corresponding technical term corresponding to the literacy level technical term. The information update unit 16 is provided that updates the literacy level corresponding to the literacy level-compatible technical term using the number of times and the number of times of understanding (S27, S33).

  Specifically, the information updating unit 16 adds 1 to the number of times of use corresponding to the replaced literacy level corresponding technical term (S15), and the acquired determination result indicates that the literacy level corresponding technical term is understood. (S17: YES), 1 is added to the number of understandings corresponding to the technical term corresponding to the literacy level (S19), and an understanding level R obtained by dividing the understanding number A by the usage number U is determined in advance. If the value is less than or equal to “0.1” (S23: YES), the literacy level corresponding to the literacy level corresponding technical term is increased (S27), while the comprehension level is a predetermined value “0”. .9 ”(S29: YES), the literacy level is decreased (S33). Therefore, if the number of uses increases, the literacy level may be set to the original value. Kill. That is, the literacy level is initially “1” or “3”, and even if this value is not the original value of the literacy level (for example, “2”), if the number of uses increases, the literacy level will eventually become the original value. Value.

  In the present embodiment, the values used for the understanding level R are “0.1” and “0.9”, but other values may be used.

  In this embodiment, the literacy level and the user literacy level are divided into three stages, but may be two stages or four or more stages as described above.

  In the literacy level compatible technical term storage unit 11, two keywords (for example, “line termination device” and “router”) are collectively associated with the literacy level, but the number of keywords is set to 1 or 3 or more. Also good.

  Further, a computer program for causing a computer to function as the technical term replacement device 1 can be recorded on a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, a magnetic tape, or a communication such as the Internet. It can be distributed widely through the network.
