Abstract

A method and system for automating categorization of statements includes a categorization system having a plurality of rules to categorize the statements, a rule engine, and a category engine. The rule engine allows for the creation and storage of objective rules used to categorize the statements. The category engine automatically applies the rules to a list of statements in order to categorize the statements and automatically determines a category label for each statement. The category engine further creates an output file including each statement and the corresponding category label. The use of objective rules to categorize the statements allows for reliable and consistent categorization results and eliminates any subjectiveness in the categorization of the statements.

Description

    TECHNICAL FIELD OF THE INVENTION
  • The present invention relates generally to information processing and management, and more specifically relates to a method and system for automated categorization of statements. [0001]
  • BACKGROUND OF THE INVENTION
  • Customers often call a company call center or access a company's web page with problems or questions about a product or service or to alter the service or product. When calling, a customer often speaks to a customer service representative (CSR) or interacts with an interactive voice response (IVR) system and explains the purpose of the inquiry in the first statement made by the customer whether that be the first words spoken by the customer or the first line of text from a web site help page or an email. These statements made by customers are often referred to as opening statements and are helpful in quickly determining the purpose of a customer's inquiry. [0002]
  • Some companies track and classify the opening statements provided by customers in order to better provide customer interfaces that are in accordance with the way customers think. Companies typically manually track the statements provided by the customers and manually categorize the statements in order to determine frequencies of occurrence with respect to how often customers inquire about certain products and/or services. Manually categorizing the statements is a difficult task that is costly, time consuming, and subjective in that the categorizations may vary based on each person's personal opinion as to how a statement should be classified. [0003]
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • A more complete understanding of the present embodiments and advantages thereof may be acquired by referring to the following description taken in conjunction with the accompanying drawing, in which like reference numbers indicate like features, and wherein: [0004]
  • FIG. 1 depicts a block diagram of a system for automating the categorization of statements; [0005]
  • FIG. 2 illustrates an example graphical user interface; and [0006]
  • FIG. 3 depicts a flow diagram of a method for the automated categorization of statements. [0007]
  • DETAILED DESCRIPTION OF THE INVENTION
  • Preferred embodiments of the present invention are illustrated in the figures, like numerals being used to refer to like and corresponding parts of the various drawings. [0008]
  • Many companies that have customer service programs and/or call centers, such as telephone companies, Internet service providers, and credit card companies, often track statements made by customers when the customers contact the company with problems or questions about a product or service or to alter a product or service. When a customer calls a service number and speaks to a customer service representative (CSR), the customer typically tells the CSR the purpose of the call in the first substantive statement the customer makes. Alternatively, a customer may contact a company via the company web site or email and generally the first substantive statement made in the email or web site response includes the customer's purpose for contacting the company. These initial statements containing the purpose of the customer's call are often referred to as opening statements. [0009]
  • These opening statements can be used by companies to better design web sites, interactive voice response (IVR) systems, and any other customer interfaces between a company and the customers. One effective way to design an IVR system or a web site interface is to analyze the scripts of incoming calls or emails to a customer support center or call center to locate the opening statements and identify the purpose of each call or email by classifying or categorizing each opening statement. Once categorized, a frequency report can be created that details how often customers are calling with specific problems or questions about specific products or services. For example, a telephone company may want to know how many customers are calling or emailing about a problem with their bill or to add a new product to their telephone service. Once a company knows the frequency of customer complaints and questions, an IVR system can be designed that incorporates the frequencies so that customers calling with common problems, complaints, or questions can be serviced quickly and efficiently. For example, a company would be able to determine that of the 5,000 service calls received in one month, what percentage of the calls were about particular topics and also rank the reasons why the customers called or emailed the customer support. [0010]
  • In order to maximize the utilization of the statements given by the customers in a customer interface design, a company therefore needs to track and categorize the statements. Typically, companies have manually tracked and manually categorized opening statements. The company manually tracks each call and manually records and transcribes each opening statement spoken to a CSR or received via email and then creates a list of opening statements. An employee of the company then sits and reads the long list of opening statements with a list of categories in front of him/her and assigns a category label to each opening statement. This has proved to be a very time consuming and costly process because one or more people manually examining every opening statement and deciding how to categorize the statement in accordance with multiple category labels requires a large amount of employee time which is expensive and would be better utilized in a revenue generating task. [0011]
  • In addition to the cost and man-power required for the manual categorization of opening statements, there is also a subjective element to the manual categorization of opening statements which affects the reliability of the categorization results. The category labels used to manually categorize the opening statements are generally designed to be objective but when applied by a person, the person's subjective thinking and opinions affect how they categorize the opening statements. For instance, an opening statement such as “I am calling about my bill for the charges for Call Waiting” may be categorized by one person as a billing inquiry and another person as a call waiting inquiry. Therefore, even though multiple people may use the same category labels to categorize the opening statements, they might categorize the same opening statement differently because the categorization is partly a matter of opinion. This human opinion factor and subjectiveness creates an inconsistency in the categorization data and frequency reports that results in unreliable data and a customer interface design that is not optimized with respect to the opening statements and the way customers think. [0012]
  • By contrast, the example embodiment described herein allows for the automated categorization of statements. Additionally, the example embodiment allows for the creation of objective rules to categorize the statements which results in reliable and consistent categorization data. Time and money is saved because people are no longer manually looking through lists of statements trying to categorize the statements using only category labels. Therefore, employees' time may be better utilized in revenue generating projects. Furthermore, the objective rules for categorizing the statements eliminate the subjective aspect of the categorization scheme allowing for the same statement to be categorized with the same category label as long as the same set of rules are used to categorize the statements. This results in consistent and reliable categorization and frequency data which can be used in the design and creation of customer interfaces that reflect the customers' view of how the interface should operate. [0013]
  • Referring now to FIG. 1, a block diagram depicts categorization system [0014] 10 for automating the categorization of statements. In the example embodiment, categorization system 10 may include respective software components and hardware components, such as processor 12, memory 14, input/output ports 16, hard disk drive (HDD) 18 containing database 20, and those components may work together via bus 24 to provide the desired functionality. The various hardware and software components may also be referred to as processing resources. Categorization system 10 may be a personal computer, a server, or any other appropriate computing device. Categorization system 10 may further include display 26 for presenting graphical user interface (GUI) 28 and input devices such as a mouse and a keyboard. Categorization system 10 also includes rule engine 30 and category engine 32, which reside in memory such as hard disk drive 18 and are executable by processor 12 through bus 24.
  • Categorization system [0015] 10 allows for the development of a one or more rules for the categorization of statements which are then applied to a list of statements in order to determine a category label for each statement. Display 26 presents GUI 28 which allows for the creation and editing of the rules and for the categorization of the statements. Shown in FIG. 1 is an example GUI 28 with GUI 28 illustrated in greater detail in FIG. 2. GUI 28 includes a plurality of buttons that allow the user to access and control the operation of rule engine 30 and category engine 32 and also display the rules that are used to categorize the statements.
  • FIG. 3 depicts a flow diagram of a method for the automated categorization of statements. The method begins at step [0016] 80 and at step 82 a user selects the statements to be categorized. Before categorization system 10 can automatically categorize the statements, the user must have one or more statements to categorize and load the list of statements into categorization system 10. The statements may be opening statements as defined above, written statements from a training session, survey responses, search statements from a web site or pop-up window, statements evaluating a customer's experience and satisfaction in a test environment, or any other appropriate response to an open-ended question that can be analyzed using content text analysis.
  • Typically, the statements are recorded, transcribed, configured in a format that can be understood by categorization system [0017] 10, and then placed in a text file which may be stored in database 20. Because there may be more than one list of statements and therefore more than one text file, the user chooses what list of statements to categorize by selecting a text file using open file button 34. Open file button 34 allows the user to view all the available files containing statements and then select the file containing the list of statements to be categorized. Once the list of statements has been selected, categorization system 10 reads the list of statements from database 20.
  • After the selection of the statements to be categorized, at step [0018] 84 the user decides whether to use rule engine 30 to create new rules to categorize the statements or use existing rules already stored in database 20 to categorize the statements. If at step 84 the user decides to create new rules, then at step 86 the user accesses rule engine 30 to create new rules. New rules are desirable when there have been new products or services recently made available to the customers and the existing rules do not reflect these new products or services or when the statements are from a new domain not covered by the existing rules, such as survey responses where all the existing rules pertain to statements from customer service call centers.
  • The user utilizes rule engine [0019] 30 and rule creation screen 50 to create new rules and then edit the newly created rules. Creation of the rules involves the use of four include boxes 52, 53, 55, and 57 and two exclude boxes 59 and 61. In alternate embodiments, there may be more or less than four include boxes and more or less than two exclude boxes. The user inputs combinations of words and text strings that should be included in the statement in order for the statement to satisfy the rule include boxes 52, 53, 55, and 57 and combinations of words and text strings that should not be in the statement in order for the statement to satisfy the rule in exclude boxes 59 and 61. Each rule is also associated with a particular category label which the user enters in category label box 54.
  • For example, a user may want to create a new rule to categorize statements with respect to the late payment of customer bills. Therefore “late” may be entered in include box [0020] 52, “bill” may be entered in include box 53, “paid” may be entered in exclude box 59, and “labill” may be entered in category label box 54. This allows for a rule that finds statements that contain the words “late” and “bill” but do not contain the word “paid.” If a statement contains the words “late” and “bill” and does not include the word “paid,” then the statement would be categorized with the category label “labill,” meaning the purpose of the statement is to inquire about a late bill that has not yet been paid.
  • Once a user enters in the desired words or text strings in include boxes [0021] 52, 53, 55, and 57 and exclude boxes 59 and 61, the user selects apply rule button 56 and the rule appears in rule screen 60 and is available to be edited and used to categorize the statements. The user may then repeat the above process to create as many rules as needed. In addition, alternate embodiments allow for rules where a noun in the singular form in include box 52 includes all forms of the noun (singular and plural) and a verb in the present tense in include box 52 includes all tenses and forms of that verb. This allows for a bigger hit rate when applying the rules to the statements since one rule is satisfied by a statements containing any form of the noun or verb and saves time because multiple rules are not required for each form of the noun or verb.
  • After the creation of the rules, at step [0022] 88 the user groups the rules into sets of rules. There may be different sets of rules for different applications or divisions of a company. For example, the marketing division may have a set of rules to categorize a list of statements while the product development division may have a different set of rules to categorize the same list of statements. This is because different users may be interested in different terms with respect to a list of statements. In addition, different sets of rules may also be necessary for different kinds of statements or statements from different domains. A user may use one set of rules to categorize opening statements from a call center and a different set of rules to categorize survey responses from a web survey questionnaire. Therefore, rule engine 30 allows for the rules to be grouped into different sets of rules with the name for each set of rules displayed in set box 58 and the sets of rules saved in database 20. In addition, the user may group only newly created rules together in a group or group together newly created rules with existing rules when creating sets of rules.
  • At step [0023] 90, the rules must be arranged in a rule order in accordance with a rule hierarchy enabling category engine 32 to apply the rules in the correct order thereby preventing inconsistent results. Typically the rule hierarchy is from specific rules to general rules but can be any other appropriate way of ordering the rules. For a specific to general rule hierarchy, category engine 32 applies the most specific rules first to a statement and then applies the more general rules if the statement does not satisfy any of the specific rules.
  • For example, a user wants to find both “phone” and “telephone” separately. A rule specifying “telephone” needs to be above the rule specifying “phone” in the rule hierarchy so that the “telephone” rule is applied to a statement before the “phone” rule is applied to a statement. If the “phone” rule is applied before the “telephone” rule, then when category engine [0024] 32 comes across a statement containing the word “telephone,” category engine 32 will find “phone” in “telephone” and categorize the statement with the “phone” category label instead of the “telephone” category label and the statement will be incorrectly categorized. But if the “telephone” rule is placed above the “phone” rule in the rule hierarchy, then category engine 32 will find “telephone” in the statement, categorize that statement with the “telephone” category label and move on to the next statement without ever applying the “phone” rule. Therefore, the most specific rules need to be placed at the top of the rule hierarchy and the most general rules need to be placed at the very end or bottom of the rule hierarchy with a gradual gradient from specific to general in-between.
  • Once the rules have been grouped and ordered in a correct rule hierarchy, rule engine [0025] 30 stores the newly created rules, sets of rules, and rule hierarchy in database 20 at step 92 so that users and category engine 32 may later access the rules. After rule engine 30 saves the rules, at step 94 the user selects the rule or the set of rules that the user wants to have category engine 32 apply to the list of statements.
  • If at step [0026] 84 the user decides to not create any new rules but instead to use existing rules, then at step 96 the user selects and edits rules from the lists of existing rules stored in database 20. Existing rules include rules that have already been created and saved by the process outlined above at steps 86 through 94. If a user has already created a set of rules that has worked well in the past in categorizing statements, then the user may want to use these rules instead of creating new rules. The user selects from the list of rules in set box 58 and the rules from the selected set of rules appear in rule screen 60. Once the rules appear in rule screen 60, the user may edit an existing rule such as rule 62 by selecting it in rule screen 60 and clicking edit rule button 46. The rule then appears in rule creation screen 50 and the user may modify include boxes 52, 53, 55, and 57 and exclude boxes 59 and 61. Once the user has a set of rules for category engine 32 to apply to the list of statements, the process continues to step 98.
  • At step [0027] 98, the user selects run button 38 and category engine 32 applies the selected rules to the list of statements in order to determine a category label for each statement. Category engine 32 cycles through the list of statements one statement at a time applying the rules to a statement until each statement satisfies a rule. Category engine 32 begins applying the rules to the list of statements at step 100 by applying the first rule in the rule hierarchy to the first statement in the list of statements. When category engine 32 applies the rules to the statements, category engine 32 strips the punctuation off the statements so that “bill,” and “bill” do not appear as two different text strings.
  • At step [0028] 102, category engine 32 determines if the statement satisfies the first rule. Category engine 32 determines if a statement satisfies a rule by searching the statement for the presence of particular text string combinations or words and the exclusion of other text string combinations or words. For instance, rule 63 is the highest rule in the rule hierarchy shown in rule screen 60. Therefore, category engine 32 searches the first statement to see if the text string “dsl” is present in the first statement. If “dsl” is not present in the first statement, then the first statement does not satisfy rule 63. If the statement does not satisfy the rule, then at step 104 category engine 32 checks to see if there are additional rules in the set of rules to apply to the statement. If there are additional rules to apply to the statement, then at step 106 category engine 32 applies the next rule in the rule hierarchy to the statement and the process returns to step 102 where category engine 32 determines if the statement satisfies this rule. Steps 102, 104, and 106 repeat until either the statement satisfies a rule at step 102 or until the statement does not satisfy any of the rules at step 102 and there are no more rules to apply to the statement at step 104.
  • If the statement satisfies a rule at step [0029] 102, then at step 108 category engine 32 assigns the category label associated with the satisfied rule to the statement. So if the statement contained the text string “dsl,” then category engine 32 assigns the “dsl” category label to the statement. But if the statement does not satisfy any of the rules at step 102 and there are no more rules left to apply at step 104, then category engine 32 applies a catch-all rule to the statement and labels the statement with the catch-all category label at step 110. The catch-all rule and category label is designed for statements that do not fit within any of the other rules. Category engine 32 labels the statement as catch-all so that the statement may be examined at a later date to determine if the statement really does not satisfy any of the rules or if there is a malfunction of categorizing system 10 which resulted in the statement not satisfying any of the rules. A high number of catch-all category labels may indicate that categorization system 10, rule engine 30, or category engine 32 are not operating correctly and require attention.
  • After category engine [0030] 32 assigns a category label to the statement at either step 108 or step 110, at step 112 category engine 32 checks to see if there are additional statements in the list of statements that require categorization. If there are additional statements to be categorized at step 112, then at step 114 category engine 32 selects the next statement to be categorized and applies the first rule in the rule hierarchy to the statement and then determines if the statement satisfies the rule at step 102. Category engine 32 repeats steps 102-112 until category engine 32 determines at step 112 that there are no additional statements to be categorized.
  • Category engine [0031] 32 then cycles through the list of statements one statement at a time to determine a category label for each statement. When category engine 32 determines a category label for a statement, category engine 32 moves to the next statement. For instance, a statement to be categorized is “I cannot access my email account.” Category engine 32 applies the first rule in rule screen 60, rule 63, to the statement. Category engine 32 applies rule 63 by searching the statement “I cannot access my email account” for the text string “dsl.” Category engine 32 determines that the statement does not contain the text string “dsl” and therefore the statement does not satisfy rule 63. Category engine 32 then applies each rule below rule 63 to the statement one rule at a time until the statement satisfies a rule. When category engine 32 gets to rule 65 and applies rule 65 to the statement, category engine 32 determines that the statement includes the text string “email” and does not include the text strings “bill” and “can't comm.” Therefore, the statement satisfies rule 65 and category engine 32 assigns category label “email” to the statement and category engine 32 checks to see if there are any additional statements to categorize.
  • When there are no additional statements to be categorized, category engine [0032] 32 creates an output file at step 116 and the process ends at step 118. The output file includes all the statements from the list of statements and each corresponding category label. An example output file with three statements is shown in Table 1. The output file allows a user to determine the frequency of occurrence for each category label and therefore determine which categories customers are calling the most about. Knowing which categories the customers are calling the most about allows for a customer interface design that takes into account the customers' way of thinking and is therefore easier to for the customer to use. The interface design that is easier for the customer to use allows the customer to accomplish their tasks in less time and a more efficient manner resulting in less company resources being used in servicing the customers and therefore lower costs for a company.
