## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This patent application is a continuation of U.S. patent application Ser. No. 15/826,093, filed Nov. 29, 2017, which is hereby incorporated by reference herein in its entirety.


FIELD OF THE DISCLOSURE
This disclosure generally relates to analyzing contact center data and, more particularly, to techniques for data matching in a contact center system.
BACKGROUND OF THE DISCLOSURE
A typical contact center algorithmically assigns contacts arriving at the contact center to agents available to handle those contacts. At times, the contact center may have agents available and waiting for assignment to inbound or outbound contacts (e.g., telephone calls, Internet chat sessions, email). At other times, the contact center may have contacts waiting in one or more queues for an agent to become available for assignment.
In some typical contact centers, contacts are assigned to agents ordered based on time of arrival, and agents receive contacts ordered based on the time when those agents became available. This strategy may be referred to as a “first-in, first-out”, “FIFO”, or “round-robin” strategy. In other typical contact centers, other strategies may be used, such as “performance-based routing”, or a “PBR” strategy.
In other, more advanced contact centers, contacts are paired with agents using a “behavioral pairing”, or a “BP” strategy, under which contacts and agents may be deliberately (preferentially) paired in a fashion that enables the assignment of subsequent contact-agent pairs such that when the benefits of all the assignments under a BP strategy are totaled they may exceed those of FIFO and other strategies such as performance-based routing (“PBR”) strategies. BP is designed to encourage balanced utilization of agents within a skill queue while nevertheless simultaneously improving overall contact center performance beyond what FIFO or PBR methods will allow. This is a remarkable achievement inasmuch as BP acts on the same calls and same agents as FIFO or PBR methods, utilizes agents approximately evenly as FIFO provides, and yet improves overall contact center performance. BP is described in, e.g., U.S. Pat. No. 9,300,802, which is incorporated by reference herein. Additional information about these and other features regarding the pairing or matching modules (sometimes also referred to as “SATMAP”, “routing system”, “routing engine”, etc.) is described in, for example, U.S. Pat. No. 8,879,715, which is incorporated by reference herein.
A BP strategy may use the outcomes of interactions between contacts and agents to build and iteratively improve pairing models. However, in some typical contact centers, outcome records may be stored separately and in an unstructured/unrelated manner relative to information stored about contact assignments to agents.
In view of the foregoing, it may be understood that there may be a need for a system that improves the accuracy of data matching for contact interaction data and contact interaction outcome data to improve the efficiency and performance of pairing strategies that are designed to choose among multiple possible pairings such as a BP strategy.

To facilitate a fuller understanding of the present disclosure, reference is now made to the accompanying drawings, in which like elements are referenced with like numerals. These drawings should not be construed as limiting the present disclosure, but are intended to be illustrative only.
FIG. 1 shows a block diagram of a contact center system according to embodiments of the present disclosure.

DETAILED DESCRIPTION
A typical contact center algorithmically assigns contacts arriving at the contact center to agents available to handle those contacts. At times, the contact center may have agents available and waiting for assignment to inbound or outbound contacts (e.g., telephone calls, Internet chat sessions, email). At other times, the contact center may have contacts waiting in one or more queues for an agent to become available for assignment.
In some typical contact centers, contacts are assigned to agents ordered based on time of arrival, and agents receive contacts ordered based on the time when those agents became available. This strategy may be referred to as a “first-in, first-out”, “FIFO”, or “round-robin” strategy. In other typical contact centers, other strategies may be used, such as “performance-based routing”, or a “PBR” strategy.
In other, more advanced contact centers, contacts are paired with agents using a “behavioral pairing”, or a “BP” strategy, under which contacts and agents may be deliberately (preferentially) paired in a fashion that enables the assignment of subsequent contact-agent pairs such that when the benefits of all the assignments under a BP strategy are totaled they may exceed those of FIFO and other strategies such as performance-based routing (“PBR”) strategies. BP is designed to encourage balanced utilization of agents within a skill queue while nevertheless simultaneously improving overall contact center performance beyond what FIFO or PBR methods will allow. This is a remarkable achievement inasmuch as BP acts on the same calls and same agents as FIFO or PBR methods, utilizes agents approximately evenly as FIFO provides, and yet improves overall contact center performance. BP is described in, e.g., U.S. Pat. No. 9,300,802, which is incorporated by reference herein. Additional information about these and other features regarding the pairing or matching modules (sometimes also referred to as “SATMAP”, “routing system”, “routing engine”, etc.) is described in, for example, U.S. Patent No. 8,879,715, which is incorporated by reference herein.
A BP strategy may use the outcomes of interactions between contacts and agents to build and iteratively improve pairing models. However, in some typical contact centers, outcome records may be stored separately and in an unstructured/unrelated manner relative to information stored about contact assignments to agents.
In view of the foregoing, it may be understood that there is a need for a system that improves the accuracy of data matching for contact interaction data and contact interaction outcome data, so as to improve the efficiency and performance of pairing strategies that are designed to choose among multiple possible pairings such as a BP strategy.
FIG. 1 shows a block diagram of a contact center system 100 according to embodiments of the present disclosure. The description herein describes network elements, computers, and/or components of a system and method for simulating contact center systems that may include one or more modules. As used herein, the term “module” may be understood to refer to computing software, firmware, hardware, and/or various combinations thereof. Modules, however, are not to be interpreted as software which is not implemented on hardware, firmware, or recorded on a processor readable recordable storage medium (i.e., modules are not software per se). It is noted that the modules are exemplary. The modules may be combined, integrated, separated, and/or duplicated to support various applications. Also, a function described herein as being performed at a particular module may be performed at one or more other modules and/or by one or more other devices instead of or in addition to the function performed at the particular module. Further, the modules may be implemented across multiple devices and/or other components local or remote to one another. Additionally, the modules may be moved from one device and added to another device, and/or may be included in both devices.
As shown in FIG. 1, the contact center system 100 may include a central switch 110. The central switch 110 may receive incoming contacts (e.g., callers) or support outbound connections to contacts via a telecommunications network (not shown). The central switch 110 may include contact routing hardware and software for helping to route contacts among one or more contact centers, or to one or more PBX/ACDs or other queuing or switching components, including other Internet-based, cloud-based, or otherwise networked contact-agent hardware or software-based contact center solutions.
The central switch 110 may not be necessary such as if there is only one contact center, or if there is only one PBX/ACD routing component, in the contact center system 100. If more than one contact center is part of the contact center system 100, each contact center may include at least one contact center switch (e.g., contact center switches 120A and 120B). The contact center switches 120A and 120B may be communicatively coupled to the central switch 110. In embodiments, various topologies of routing and network components may be configured to implement the contact center system.
Each contact center switch for each contact center may be communicatively coupled to a plurality (or “pool”) of agents. Each contact center switch may support a certain number of agents (or “seats”) to be logged in at one time. At any given time, a logged-in agent may be available and waiting to be connected to a contact, or the logged-in agent may be unavailable for any of a number of reasons, such as being connected to another contact, performing certain post-call functions such as logging information about the call, or taking a break.
In the example of FIG. 1, the central switch 110 routes contacts to one of two contact centers via contact center switch 120A and contact center switch 120B, respectively. Each of the contact center switches 120A and 120B are shown with two agents each. Agents 130A and 130B may be logged into contact center switch 120A, and agents 130C and 130D may be logged into contact center switch 120B.
The contact center system 100 may also be communicatively coupled to an integrated service from, for example, a third party vendor. In the example of FIG. 1, data matching module 140 may be communicatively coupled to one or more switches in the switch system of the contact center system 100, such as central switch 110, contact center switch 120A, or contact center switch 120B. In some embodiments, switches of the contact center system 100 may be communicatively coupled to multiple data matching modules. In some embodiments, data matching module 140 may be embedded within a component of a contact center system (e.g., embedded in or otherwise integrated with a switch, or a “BP switch”). The data matching module 140 may receive information from a switch (e.g., contact center switch 120A) about agents logged into the switch (e.g., agents 130A and 130B) and about incoming contacts via another switch (e.g., central switch 110) or, in some embodiments, from a network (e.g., the Internet or a telecommunications network) (not shown).
A contact center may include multiple pairing modules (e.g., a BP module and a FIFO module) (not shown), and one or more pairing modules may be provided by one or more different vendors. In some embodiments, one or more pairing modules may be components of data matching module 140 or one or more switches such as central switch 110 or contact center switches 120A and 120B. In some embodiments, a BP module may determine which pairing module may handle pairing for a particular contact. For example, the BP module may alternate between enabling pairing via the BP module and enabling pairing with the FIFO module. In other embodiments, one pairing module (e.g., the BP module) may be configured to emulate other pairing strategies. For example, a BP module, or a BP component integrated with BP components in the BP module, may determine whether the BP module may use BP pairing or emulated FIFO pairing for a particular contact. In this case, “BP on” may refer to times when the BP module is applying the BP pairing strategy, and “BP off” may refer to other times when the BP module is applying a different pairing strategy (e.g., FIFO).
In some embodiments, regardless of whether pairing strategies are handled by separate modules, or if some pairing strategies are emulated within a single pairing module, the single pairing module may be configured to monitor and store information about pairings made under any or all pairing strategies. For example, a BP module may observe and record data about FIFO pairings made by a FIFO module, or the BP module may observe and record data about emulated FIFO pairings made by a BP module operating in FIFO emulation mode.
FIG. 2 shows a block diagram of a contact center system 200 according to embodiments of the present disclosure. The contact center system 200 may be the same contact center system as contact center system 100 (FIG. 1), with additional modules and storage databases showing examples of where data may be transferred and stored throughout a contact center system.
In the example of contact center system 200, four example storage systems are shown: historical assignment database 210, contact center database 220, customer relationship management (“CRM”) database 230, and outcome records database 240. In some embodiments, some types of data stored in these databases may be stored in the same or different databases. Some databases may not be present, and other databases not shown may be present. In some embodiments, a database may be communicatively coupled to the contact center system from a remote (e.g., cloud-based) data center via a network connection. In other embodiments, a database may be co-located with certain contact center equipment on premises. The various databases are shown as being communicatively coupled to various contact center system components. For example, contact center switch 120A is shown as being communicatively coupled to the four aforementioned databases. In some embodiments, contact center switch 120A or other contact center system components may be communicatively coupled to more or fewer databases.
Consider a contact waiting for assignment at contact center switch 120A: When the contact is paired (i.e., assigned) and connected to an agent such as Agent 130A, some information about the assignment may be stored in contact center system 200. For example, a record of the assignment may be stored in historical assignment database 210 and/or the contact center database 220. The record may include an identifier for the contact (e.g., phone number, customer identifier, email address), an identifier for the agent (e.g., agent ID, agent name), a timestamp for the date and time when the assignment was made, and other information relevant for the assignment. In some embodiments, the record may include additional information about the contact's journey through the contact center system, such as interactive voice response (“IVR”) or touch-tone menu selections the contact may have made prior to being assigned to Agent 130A in the example of a telephone call.
In some embodiments, the historical assignment database 210 may also track which of several pairing strategies (e.g., BP or FIFO) was used to make the assignment, or whether the assignment was an optimized choice or a constrained choice, such as when a service level agreement has been exceeded for the contact. In some embodiments, one or more databases such as the historical assignment database 210 may be supplied by a third-party vendor, such as a BP vendor.
When the contact disconnects from the contact center system (e.g., hangs up the phone), the contact center switch 120A may record additional information in the historical assignment database 210 and/or the contact center database 220. For example, the contact center switch 120A may be configured to store the disconnect time or the duration of the interaction in one of the databases.
In the example of contact center system 200, contact center switch 120A and/or Agent 130A are communicatively coupled or otherwise connected to agent desktop system 250. In some embodiments, agent desktop system 250 is a computer processor-implemented system for managing various agent tasks. For example, agent desktop system 250 may allow Agent 130A to indicate when Agent 130A is logged into the contact center system 200, when Agent 230A is occupied with a contact interaction (or, in some embodiments, multiple simultaneous interactions such as chat-based interactions), when Agent 130A is idle or otherwise available for another contact interaction, and when Agent 130A is not available (e.g., taking a break, offline).
In some embodiments, agent desktop system 250 may present information about the contact or the contact interaction to Agent 130A during the interaction. For example, agent desktop system 250 may present information from CRM database 230 about the contact's customer relationship with Agent 130A's company, or agent desktop system 250 may present information from contact center database 220 about prior interactions the contact has had with contact center system 200.
In some embodiments, during the interaction and/or after the interaction, Agent 130A may use agent desktop system 250 to input information about the outcome of the interaction. For example, Agent 130A may type notes into agent desktop system 250 that may be stored in contact center database 220 for reference during future interactions. In the case of a sales queue environment, Agent 130A may enter a sales transaction. Data about the sales transaction may be stored in, for example, the outcome records database 240 and/or the CRM database 230. In some situations, data about a sale may be transferred to a fulfillment center or a fulfillment system. In the case of a customer support queue environment, Agent 130A may update the contact's records in one of the databases to reflect the resolution of the call, such as a refund or courtesy credit, an upgrade or downgrade in services, a cancellation of services, or a request to a dispatch center system to schedule a “truck roll” or field agent to attend to the contact's support request.
In any of these cases, agent desktop system 250 may record a timestamp associated with the outcome record in the outcome records database 240 or changes to other records in the CRM database 230 or other database. In some scenarios, the timestamp associated with an agent completing a outcome record such as a sales transaction may be during a contact interaction. In other scenarios, the timestamp associated with the agent completing the outcome record may be after the conclusion of the contact interaction.
For example, consider a contact that arrived at the contact center switch 120A at 10:00 AM. A BP pairing module instructed the contact center switch 120A to pair the contact with Agent 130A, who was available for assignment to the contact. The contact center switch 120A connected the contact to Agent 130A at 10:02 AM, and the interaction began. During the interaction, the contact decided to purchase a new cellphone. Agent 130A recorded the transaction using the agent desktop system 250, completing the transaction at 10:10 AM. Agent 130A subsequently disconnected the call at 10:12 AM. After disconnecting the call, Agent 130A entered a few additional notes in the agent desktop system 250.
The pairing of the contact to Agent 130A by a BP strategy may have been logged in the historical assignment database 210. The date, start time, and end time and/or duration of the contact interaction event may have been logged in, for example, the contact center database 220. The fact that a sale was completed, as well as the type and amount of sale, the date and time of the sale, and identities of the contact and agent who completed the sale, may have been logged in the outcome records database 240. Information about the contact such as the type of the newly purchased cellphone, may have been logged in the CRM database 230. Hundreds or thousands of similar contact interactions may be recorded over the course of an hour or day in a real-world contact center system with dozens, hundreds (or more) agents.
In the example of contact center system 200, data matching module 140 is communicatively coupled with each of the historical assignment database 210, the contact center database 220, the CRM database 230, and the outcome records database 240. In some embodiments, a BP module may need to generate a new pairing model, update an existing pairing model with new data, or benchmark the performance of a BP strategy against the performance of another strategy such as FIFO or PBR. In these embodiments, data matching module 140 may retrieve and match data from at least two disparate or unstructured data sources. In some embodiments, each database may contain structured data; however, the data may not be structured or otherwise related or linked to the data in another database or other storage location. Moreover, in some environments, a database store on one system may be in a different time zone or otherwise out of time synchronization with another database store on another system.
The data matching module 140 may use various techniques for mapping or matching events logged in one database with corresponding events logged in another database. For example, in the call center domain (assuming one caller per agent at a given time), the call start and end time, and an identifier for the agent on the call, may establish a call event across all databases. Additionally, sometimes the call event may extent past the recorded end/disconnect time, such as when an agent takes time after disconnecting from a call to complete a transaction or other record-updating process. The various heuristics or other techniques used by the data matching module 140 may vary from one process or context to the next and across different contact center systems.
For example, a data matching heuristic may be to add two minutes (or more or less time) to the end time of a call event to account for time an agent may take to enter results into a system after a call ends. If Agent 130A recorded a sale at 9:30 AM, it might be correct to match this outcome with a call that ended at 9:29 AM.
For another example, a data matching heuristic may be to reject matching a sale outcome record that occurred earlier than the recorded start time of a call. If Agent 130A recorded a sale at 11:18 AM, it should not be matched with a call that did not begin until 11:19 AM.
In some cases, there may be multiple candidate outcome records for a given call event, or vice versa. In these cases, the data matching module 140 may determine a probability that a given pair of a candidate outcome and interaction event is a correct match. The data matching module 140 may select the pair with the highest probability of correctness. In some environments, it may be possible for multiple outcomes to be associated with one or more interactions. In these environments, the data matching module 140 may perform one-to-many or many-to-many mappings of outcomes to interactions.
For another example, a data matching heuristic may be to reject matching a sale outcome record that occurred relatively early during an interaction. If a call ran from 11:19-11:31 AM, and a sale was recorded at 11:20 AM, the time of the sale fell within the time window of the call. However, it may be unlikely for a sale to occur quickly, just one minute after the call began, only for the call to continue for another 11 minutes. This candidate match may be outright rejected, or otherwise given a low probability of correctness, which a search may continue for a more likely match. For example, another agent may have taken a call from 11:08-11:21 AM. The sale outcome at 11:20 AM is more likely to have occurred during this other call.
In other embodiments, data matching module 140 may assign a probability to a candidate outcome and interaction event. Even if only one such pairing is found for a given interaction event, the match may be accepted or rejected depending on whether the probability exceeds a predetermined threshold (e.g., greater than 50%, 90%, 99.99% likelihood of the match being correct).
In some embodiments, under-constraining the analysis by the data matching module 140 may produce a higher match rate, providing more data but less accurate data. In other embodiments, over-constraining the analysis (i.e., rejecting more matches) may produce a lower match rate, providing less data but more accurate data. For a given degree of constraint and a given mapping resulting from the given constraint, the data matching module 140 may determine a measure of the match rate and/or a measure of the accuracy of the matched data.
In some embodiments, some of the databases communicatively coupled with the contact center system 200 may have incorrect or incomplete records. Data matching module 140 may be trained to identify and flag potential data issues. For example, it is unlikely that for an experienced agent to have zero sales. If an outcome records database suggests that an agent has zero sales, it is more likely that there was an error recording the identity of the agent than that the agent struck out with a 0% conversion rate during the agent's shift. The data matching module 140 may flag this problem so that the contact center system 200 may analyze the problem or raise the issue to a contact center system administrator for troubleshooting.
For another example, if the times from the first call to the last call of a shift as recorded in a contact center database or historical assignment database do not approximately match the times from the first sale to the last sale as recorded in an outcome records database, there may be a problem with the way the data has been recorded. If an outcome records database suggests that the contact center did not make any sales during the last two hours of a shift despite normal call volume, it is more likely that an error occurred with recording sales in the outcome records database. Again, this type of data inconsistency may be detected and reported by the data matching module 140.
For another example, the data matching module 140 may detect that an agent appears to have completed sales outside the time window for the agent's shift. If an agent's shift ended at 3:00 PM, but an outcome records database shows that this agent completed a sale at 5:37 PM, the data matching module 140 may flag and report this inconsistency.
FIG. 3 shows a flow diagram of a data matching method 300 according to embodiments of the present disclosure. Data matching method 300 may begin at block 310.
At block 310, an interaction event time associated with a historical contact interaction may be determined. For example, a data matching module such as data matching module 140 (FIGS. 1 and 2) may retrieve sets of records from various databases such as a historical assignment database 210 (FIG. 2) and/or a contact center database 220 (FIG. 2). The data matching module may determine the event time of the interaction. If the interaction was a telephone call, the event time may be a combination of the start date and time of the call and the end date and time of the call. Having determined the interaction event time associated with the historical contact interaction (or a plurality of historical contact interactions), data matching method 300 may proceed to block 320.
At block 320, an outcome event time associated with a historical contact interaction outcome may be determined. For example, the data matching module may retrieve sets of records from various databases such as a CRM database 230 (FIG. 2) and/or an outcome records database 240 (FIG. 2). The data matching module may determine the outcome (or “result”) time of the interaction outcome. If the interaction was a telephone call in a sales queue, the interaction outcome event time may be a time at which a sales transaction was completed. Depending on the environment, the sales transaction could be completed, for example, during the call (e.g., prior to—but close to—the end time of the call), or it could be completed shortly after the end time of the call. Having determined the outcome event time associated with the historical contact interaction outcome/result (or a plurality of historical contact interaction outcomes), data matching method 300 may proceed to block 330. In some embodiments, block 320 may be performed before block 310 or in parallel with block 310.
At block 330, one or more interaction event times determined at block 310 may be analyzed in conjunction with one or more outcome event times determined at block 320 to determine correlations between a pair of an interaction event time and an outcome event time. In some environments, additional data fields may be used to eliminate certain candidate pairs or increase the probability/likelihood that a candidate pair is a correct match. For example, if agent identifiers are stored in both the interaction database and the outcome database, the agent identifier field may be used to eliminate pairs for which the agent identifiers do not match. The data matching module may apply various heuristics and other statistical analysis or machine learning techniques to the data sets to determine correlations for candidate pairs such as those described above with reference to FIG. 2. Having determined one or more correlations for one or more candidate pairs of interaction event times and outcome event times, data matching method 300 may proceed to block 340. At block 340, one or more candidate pairs may be deemed a correct match (e.g., if the correlation or probability of correctness exceeds a predetermined threshold degree of likelihood). The historical contact interaction outcome may be matched with the historical contact interaction. Matched pairs of interactions and interaction outcomes may be processed (or stored for later processing) by the data matching module or another module (such as a BP module or a benchmarking module) to create or improve a pairing model, or to assess the performance of one pairing strategy against another. Having matched one or more pairs of historical contact interaction outcomes with historical contact interactions, data matching method 300 may end. In some embodiments, data matching method 300 may return to block 310 for further processing of new or otherwise additional interaction events and outcome events.
At this point it should be noted that data matching in a contact center system in accordance with the present disclosure as described above may involve the processing of input data and the generation of output data to some extent. This input data processing and output data generation may be implemented in hardware or software. For example, specific electronic components may be employed in a behavioral pairing module or similar or related circuitry for implementing the functions associated with data matching in a contact center system in accordance with the present disclosure as described above. Alternatively, one or more processors operating in accordance with instructions may implement the functions associated with data matching in a contact center system in accordance with the present disclosure as described above.
