Conversational software which emulates a customer service agent, hereinafter, “chatbots,” are often able to assist customers. These chatbots determine a semantic meaning of the customer's query and attempt to provide an answer from a database of answers.
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
With the rise of the internet and other network-based communication mediums, companies are utilizing these mediums to expand the ways they can reach and support their customers. For example, network based computing services such as social networking services are embraced by companies as a way of communicating with customers. Persons may communicate using the social networking service by posting a message on a profile page of a user, participating in chats hosted by a social networking service, direct messaging, or the like.
While communicating with customers through these new mediums is convenient for the customer, it increases costs of the company as it adds another support channel that needs to be staffed. In some examples, in order to reduce these costs, the company may employ chatbot software on these channels. For example, a customer may come to a social networking profile page of the organization and start a chat session. The message the user enters into the profile page chat window may be sent to a network-based chat service that may determine a semantic meaning of the user's message, select an appropriate response, and send the response back to the social networking service for display in the chat session.
In some cases the chatbots may not be able to help the user. For example, the user may have a question that the chatbot is not programmed to answer, the user may be angry and may not want to chat with the chatbot, or the like. In these instances, presently, the user may have to disconnect with the chatbot and find an alternative method of contacting the company. This is not seamless to the customer and introduces obstacles to resolving the customer's problem. Some customers may give up and take their business to a competitor rather than find another channel.
Disclosed in some examples are methods, systems, and machine-readable mediums which provide for customer support chatbots that detect a customer handoff condition and in response, transfer the customer to a communication session with a live agent. The handoff condition may comprise an inability to understand the customer, an inability to answer the customer's question, expressions of frustration or anger on the part of the customer, a customer's express request to be transferred, or the like. The live agent may receive a partial or complete history of the conversation with the chatbot so that the customer does not have to repeat him or herself to the live agent. In some examples, the chatbot chat session may be linked to a social networking account of the customer and may take place in association with a social networking profile page of the company.
On some social networking services, such as FACEBOOK®, these social networking services are structured so as to allow only a single application the ability to post messages in a chat on the social networking service (in some examples, multiple applications may read the chats). For example, the social networking service provides web hooks that are HTTP requests (e.g., POST calls) that happen upon the occurrence of an event, such as a message entered by a user. The social networking service sends an HTTP request (such as a POST message) to the web hook address upon occurrence of an event (e.g., the user enters a message). The chatbot application listens for these HTTP requests at the given address and then responds by utilizing another HTTP call (e.g., a POST call) which is then posted to the chat by the social networking service.
As noted, it is not possible to have messages delivered to both a chatbot service and a live agent. Thus, the chatbot may be “attached” to the chat page, and it is not possible for the live agent to also send messages to the user via the chat. In some examples, as disclosed herein, to solve this problem, the chatbot, upon detection that the customer is unsatisfied with the chatbot, may provide a link to a second chat page provided by the social networking service which may be attached to an application which allows for a customer service agent to directly communicate with the customer.
In other examples, another solution to this problem is to route the web hooks to a chat routing application. This chat routing application may route the chat messages to either the chatbot or to a live agent. In some examples, the chat router may default to the chatbot. The chatbot may signal the router that the conversation should be transferred to a live agent. In these examples, once the signal is received, the router then routes subsequent communications to the live agent. The live agent may later transfer control back to the chatbot. In some examples, messages may be individually routed to either the chatbot or the live agent. For example, the message may be first routed to the chatbot. The chatbot may have a confidence level associated with an automatically generated answer with respect to the chatbots ability to accurately answer the question. If the confidence level of the answer is below a predetermined threshold, one or both of the user's communication and the chatbot's proposed answer may be sent (e.g., directly, or forwarded through the chat routing application) by the chat router to the live agent.

In some examples, should the chat service 1050 detect a customer hand off event, the chat service 1050 may send a link to a second page (e.g., profile page 1030) to the social networking service 1010 for posting in the chat GUI element displayed in profile page 1020. The user of customer computing device 1040 may follow this link (e.g., by clicking, tapping, or otherwise activating it) which may redirect a web browser or other application executing on the customer computing device 1040 to the web address of profile page 1030. The user may then enter a message through a chat GUI element on profile page 1030 which may be routed through web hooks by social networking service 1010 to agent service 1070. Agent service 1070 may be a network-based service that monitors one or more social networking profile pages for activity.
Once activity is detected, the agent service 1070 may provide tools for agent computing devices 1080 to communicate with the customers. For example, if the customer computing device 1040 sends a message to the organization through profile page 1030, the agent service may receive the web hook callback. This callback may then be routed to an appropriate agent computing device 1080. The agent may utilize agent computing device 1080 to reply (through the agent service 1070). For example, the agent computing device 1080 may send a reply to agent service 1070, which may forward the reply to the social networking service 1010 for posting to the profile page 1030.

Response 2050 is sent back to the social networking service for display in the profile page 1020. This is then sent to the customer device 1040 with response message 2060. Second message 2070 from the user entered on their customer computing device 1040 in a GUI element of the profile page 1020 (e.g., the same GUI element used to enter message 2010) may be sent to chat service 1050 with message 2080. Chat service 1050 may send a response 2090 with a link to a second profile page. For example, the chat service 1050 may detect a hand-off condition and in response send the link. The response 2100 may be received by the customer computing device 1040 through the profile page 1020.

In some examples, the customer's chat history with the chatbot may be available to the agent. For example, the social networking service may allow multiple web hooks for monitoring (but not posting to) the profile page 1020. In these examples, the agent service 1070 may monitor these pages and when there is a handoff event, it may route the chat history to the agent computing device 1080.

In some examples, the chat service 1050 may implement a machine learning algorithm. The chat router 4020 or the agent service 1070 may utilize the message 4030 along with the live agent's response to refine the machine-learning model in the chat service 1050. In this way, the chatbot may continuously improve the quality of its responses. In some examples, the chat router 4020 may send the message 4050 to both the agent service 1070 and the chat service 1050. The corresponding responses may then be scored by the chat router based upon a machine learning algorithm implemented by the chat router that is trained using appropriate responses for a training set of questions. The chat router 4020 may then send the response that scored the highest and/or the relevancy or appropriateness rating (e.g., the response from either the agent service 1070 or the chat service 1050). In some examples, the chat router 4020 may send the message 4050 and receive the reply 4060 to the chat service 1050 first. The message 4050 and the reply 4060 may then be both forwarded to the agent service 1070. The chatbot's answer may assist the agent in determining an appropriate answer. The agent may then respond appropriately and either forward the chatbot's answer 4060 as the answer or another answer.

The handoff condition may comprise one or more of an inability to understand the customer, an inability to answer the customer's question, expressions of frustration or anger on the part of the customer, a customer's express request to be transferred, or the like. Example methods of detecting handoff conditions include an inability to parse the message in operation 5020, keywords or key phrases in the message (e.g., “I want to speak to a person”, “I'm angry”), sentiment of the message (e.g., angry) and the like.
In other examples, a machine learning classifier such as a support vector machine, logistic regression, Bayes point machine, decision forest, boosted decision tree, neural network is used to determine whether or not to handoff the conversation. This machine learning algorithm may be trained with conversations that are labeled (e.g., as do not hand off or hand off). Once the model is trained, new conversations may then be classified to determine whether a handoff condition is present by the machine learned model.
At operation 5040 if a handoff condition is detected, the link to a chat session with an agent may be determined. For example, the link may be a predetermined link that is set by an administrator or hard coded. In other examples, the link may be to one of many chat pages that are associated with an agent service (such as agent service 1070) of the organization. For example, the chat service 1050 may contact agent service 1070 and request a link. Agent service 1070 may provide a link that is selected from a plurality of links based upon wait time for an agent. Once a link is determined, at operation 5050 a message is constructed with the link as part of the message and sent to the social networking service for posting in the GUI element of the chat.
At operation 5060 if a handoff condition is not detected, the chat service determines a reply message. For example, based upon the intent determined in operation 5020, a predetermined reply for the determined intent may be used. In other examples, various machine learning algorithms may be utilized to determine a reply message (e.g., from a predetermined list of responses). In some examples, a request for information from an information service (e.g., information service 1060) may be made as part of determining the reply message. At operation 5070 a message is constructed with the reply as part of the message and sent to the social networking service for posting in the GUI element of the chat.

At operation 6030 if the message is to be routed to the chatbot, it is sent to the chat service (for example, by utilizing a web hook of the chat service registered with the chat router). At operation 6040 if the message is to be routed to an agent, it is sent to the agent service (for example, by utilizing a web hook registered with the agent service). At operation 6050 the chat router receives a reply message (from either the agent service or the chat service). At operation 6060 the reply is sent back to the customer. For example, by sending it to the social networking service for display in the chat GUI.

Examples herein may have been described with reference to a social networking service. In some examples, the concepts disclosed herein are applicable to any chatbot session and are not limited to social networking services, but are broadly applicable to other types of network-based communications in general. A social networking service is a type of network-based service provided by one or more computer systems accessible over a network that allows members of the service to build or reflect social networks or social relations among members. Members may be individuals or organizations. Typically, members construct profiles, which may include personal information such as the member's name, contact information, employment information, photographs, personal messages, status information, multimedia, links to web-related content, blogs, and so on. In order to build or reflect the social networks or social relations among members, the social networking service allows members to identify, and establish links or connections with other members. For instance, in the context of a business networking service (a type of social networking service), a member may establish a link or connection with his or her business contacts, including work colleagues, clients, customers, personal contacts, and so on. With a social networking service, a member may establish links or connections with his or her friends, family, or business contacts. A connection may be formed using an invitation process in which one member “invites” a second member to form a link. The second member then has the option of accepting or declining the invitation.
In general, a connection or link represents or otherwise corresponds to an information access privilege, such that a first member who has established a connection with a second member is, via the establishment of that connection, authorizing the second member to view or access certain non-publicly available portions of their profiles that may include communications they have authored. Example communications may include blog posts, messages, “wall” postings, or the like. Of course, depending on the particular implementation of the business/social networking service, the nature and type of the information that may be shared, as well as the granularity with which the access privileges may be defined to protect certain types of data may vary.
Some social networking services may offer a subscription or “following” process to create a connection instead of, or in addition to the invitation process. A subscription or following model is where one member “follows” another member without the need for mutual agreement. Typically in this model, the follower is notified of public messages and other communications posted by the member that is followed. An example social networking service that follows this model is Twitter®—a micro-blogging service that allows members to follow other members without explicit permission. Other connection-based social networking services also may allow following-type relationships as well. For example, the social networking service LinkedIn® allows members to follow particular companies.
Examples, as described herein, may include, or may operate on, logic or a number of components, modules, or mechanisms. For example, the components of
Accordingly, the term “module” is understood to encompass a tangible entity, be that an entity that is physically constructed, specifically configured (e.g., hardwired), or temporarily (e.g., transitorily) configured (e.g., programmed) to operate in a specified manner or to perform part or all of any operation described herein. Considering examples in which modules are temporarily configured, each of the modules need not be instantiated at any one moment in time. For example, where the modules comprise a general-purpose hardware processor configured using software, the general-purpose hardware processor may be configured as respective different modules at different times. Software may accordingly configure a hardware processor, for example, to constitute a particular module at one instance of time and to constitute a different module at a different instance of time.
Machine (e.g., computer system) 8000 may include a hardware processor 8002 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), a hardware processor core, or any combination thereof), a main memory 8004 and a static memory 8006, some or all of which may communicate with each other via an interlink (e.g., bus) 8008. The machine 8000 may further include a display unit 8010, an alphanumeric input device 8012 (e.g., a keyboard), and a user interface (UI) navigation device 8014 (e.g., a mouse). In an example, the display unit 8010, input device 8012 and UI navigation device 8014 may be a touch screen display. The machine 8000 may additionally include a storage device (e.g., drive unit) 8016, a signal generation device 8018 (e.g., a speaker), a network interface device 8020, and one or more sensors 8021, such as a global positioning system (GPS) sensor, compass, accelerometer, or other sensor. The machine 8000 may include an output controller 8028, such as a serial (e.g., universal serial bus (USB), parallel, or other wired or wireless (e.g., infrared (IR), near field communication (NFC), etc.) connection to communicate or control one or more peripheral devices (e.g., a printer, card reader, etc.).
The storage device 8016 may include a machine readable medium 8022 on which is stored one or more sets of data structures or instructions 8024 (e.g., software) embodying or utilized by any one or more of the techniques or functions described herein. The instructions 8024 may also reside, completely or at least partially, within the main memory 8004, within static memory 8006, or within the hardware processor 8002 during execution thereof by the machine 8000. In an example, one or any combination of the hardware processor 8002, the main memory 8004, the static memory 8006, or the storage device 8016 may constitute machine readable media.
While the machine readable medium 8022 is illustrated as a single medium, the term “machine readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) configured to store the one or more instructions 8024.
The term “machine readable medium” may include any medium that is capable of storing, encoding, or carrying instructions for execution by the machine 8000 and that cause the machine 8000 to perform any one or more of the techniques of the present disclosure, or that is capable of storing, encoding or carrying data structures used by or associated with such instructions. Non-limiting machine readable medium examples may include solid-state memories, and optical and magnetic media. Specific examples of machine readable media may include: non-volatile memory, such as semiconductor memory devices (e.g., Electrically Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM)) and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; Random Access Memory (RAM); Solid State Drives (SSD); and CD-ROM and DVD-ROM disks. In some examples, machine readable media may include non-transitory machine readable media. In some examples, machine readable media may include machine readable media that is not a transitory propagating signal.
The instructions 8024 may further be transmitted or received over a communications network 8026 using a transmission medium via the network interface device 8020. The Machine 8000 may communicate with one or more other machines utilizing any one of a number of transfer protocols (e.g., frame relay, internet protocol (IP), transmission control protocol (TCP), user datagram protocol (UDP), hypertext transfer protocol (HTTP), etc.). Example communication networks may include a local area network (LAN), a wide area network (WAN), a packet data network (e.g., the Internet), mobile telephone networks (e.g., cellular networks), Plain Old Telephone (POTS) networks, and wireless data networks (e.g., Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards known as Wi-Fi®, IEEE 802.16 family of standards known as WiMax®), IEEE 802.15.4 family of standards, a Long Term Evolution (LTE) family of standards, a Universal Mobile Telecommunications System (UMTS) family of standards, peer-to-peer (P2P) networks, among others. In an example, the network interface device 8020 may include one or more physical jacks (e.g., Ethernet, coaxial, or phone jacks) or one or more antennas to connect to the communications network 8026. In an example, the network interface device 8020 may include a plurality of antennas to wirelessly communicate using at least one of single-input multiple-output (SIMO), multiple-input multiple-output (MIMO), or multiple-input single-output (MISO) techniques. In some examples, the network interface device 8020 may wirelessly communicate using Multiple User MIMO techniques.
