Abstract

The customer experience is enhanced by detecting leakage-to-voice from chats and providing recommendations to operations, chat agents, and customers. A chat is classified into leakage-to-voice or leakage-to-text chat and actionable recommendations are then provided to operations, chat agents, and customers based on the leakage information. Once leakage is identified, various other insights are extracted from chats and such insights are fed into the knowledge-base. Such insights also used in agent training and are provided to chat agents as recommendations. This results in a better customer experience.

Claims

1. A computer implemented method for analyzing chat leakage, comprising:

providing a processor configured for obtaining chat-related information from at least one chat session between a customer and an agent;

said processor configured for identifying customer leakage information from said chat to another channel;

said processor configured for building a model based on said chat-related information and said leakage information;

said processor configured for applying said model to provide recommendations to said agent for said customer to improve the customer'"'"'s experience and accordingly prevent or reduce leakage;

said applying said model further comprising;

when chat leakage is identified, analyzing said chat to determine factors that have contributed to said leakage;

storing data pertaining to said leakage and said analysis results in a knowledge base; and

using information and analysis thereof stored in said knowledge base to train agents and to make recommendations to agents and managers to improve the customer experience.

2. The method of claim 1, further comprising:

classifying chats that are identified as having leakage into leakage-to-voice or leakage-to-text chats.

3. The method of claim 1, further comprising:

said chat agent performing any of providing solutions to customer issues and redirecting said chat to other channels to resolve said customer issues.

4. The method of claim 1, further comprising:

said chat agent checking information related to the customer, said information comprising any of the customer'"'"'s journey, the customer'"'"'s communication history, the customer'"'"'s interests, and other information associated with the customer.

5. The method of claim 1, wherein the customer'"'"'s journey comprises any of:

identity of chat agents, either a voice or a text chat agent, who interacted with the customer before the customer visited a specific chat agent;

a path taken by the customer to reach a chat agent;

the customer'"'"'s Web-log journey; and

other customer information.

6. The method of claim 1, wherein the customer'"'"'s journey comprises any of a virtual journey, a literal journey, an assisted journey, a guided journey, and a combination thereof.

7. The method of claim 1, further comprising:

identifying a channel to which leakage occurs.

8. The method of claim 1, further comprising:

using sample production data to build said model.

9. The method of claim 1, building said model further comprising:

using a chat text to build an anchor.

10. The method of claim 9 further comprising:

extracting channel names referred in the chat text to build said anchor.

11. The method of claim 9, further comprising:

after said anchor is built, using positive hits generated during anchor building in connection with edit-distance to obtain a temporary categorization of a team/department.

12. The method of claim 11, further comprising:

business analysts using business sense for each team/department and customer needs to perform an initial grouping of a portion of teams/departments.

13. The method of claim 11, further comprising:

applying a service layer to fine tune category mapping of said team/department; and

generating a model that includes a final category for each team/department name.

14. The method of claim 13, wherein said category comprises a categories grouping for each team/department name based on edit distance.

15. The method of claim 11, further comprising:

after said anchor is built, categorizing said chat data into said team/department names.

16. The method of claim 15, further comprising:

applying specific filters for voice and text chat categorization.

17. The method of claim 16, wherein said filters and said team/department names occur in a periphery of a predefined number of words;

and

said voice and text chat filters creating dummy data having a periphery of said predefined number of words, instead of using an entire agent chat text; and

providing said dummy data with a dummy identifier.

18. The method of claim 16, further comprising:

providing a priority index to control each of said filters.

19. The method of claim 18, further comprising:

providing a grid editor to provide said priority to said filters.

20. The method of claim 9, wherein said chat text is any of text provided by said customer and by said agent.

21. The method of claim 15, further comprising:

performing a noun extraction process in which a part-of-speech (pos) tagger is used to tag lines in the chat based on pos information.

22. The method of claim 21, wherein a first noun from the line of chat text is extracted based on the hypothesis that most of the time the product name is mentioned as the first noun.

23. The method of claim 15, further comprising:

looking up a concordance words with the anchors;

wherein said concordance comprises any of direction (left window/right window/around window) and the window size; and

wherein based on the direction, positive hits are generated by the anchor building process.

24. The method of claim 15, further comprising:

performing a noun phrase extraction process in which a part-of-speech (pos) tagger is used to tag lines in the chat text based on pos information.

25. The method of claim 24, wherein a first noun from the line of chat text is extracted based on the hypothesis that most of the time the product name is mentioned as the first noun.

26. The method of claim 15, further comprising:

performing a stopword removal process to remove stopwords from the chat text.

27. The method of claim 15, further comprising:

performing a get unique word process to remove multiple occurrences of the same team/department names.

28. The method of claim 15, further comprising:

performing a surface-similarity process in which a surface similarity measure is used to determine edit-distance at a word level or at a character level; and

grouping team/department names in a category of the team/department based on similar words.

29. The method of claim 15, further comprising:

including the agent'"'"'s names as a variable for use in evaluating the agents'"'"' performance.

30. The method of claim 29, further comprising:

mapping chat agent performance data with a customer satisfaction score (CSAT) driver and;

based thereon, providing actionable recommendations to operations and agents.

31. The method of claim 1, further comprising:

passing contextual information to a voice channel.

32. The method of claim 1, further comprising:

passing insights from one channel to a next channel.

33. The method of claim 1, further comprising:

detecting leakage and extracting substantially all contextual and other relevant information from a chat interaction when there is a customer dropout during a chat and the agent cannot solve the customer problem; and

summarizing said relevant information and passing said summarized information to a voice referral.

34. The method of claim 1, further comprising:

adding information regarding leakage to a Web-log journey to predict leakage at the start of a subsequent customer journey when leakage in a current chat is detected; and

providing recommendations to said agent at the start of said subsequent chat, based on leakage detected in said current chat.

35. The method of claim 1, further comprising:

said processor configured for applying said model to provide off line training analysis.

36. An apparatus for analyzing chat leakage, comprising:

a processor obtaining chat-related information from at least one chat session between a customer and a chat agent;

said processor identifying customer leakage information from said chat to another channel;

said processor building a model based on said chat-related information and said leakage information; and

said processor applying said model to provide recommendations to said chat agent to improve the customer'"'"'s experience and accordingly prevent or reduce leakage;

said applying said model further comprising;

when chat leakage is identified, analyzing said chat to determine factors that have contributed to said leakage;

storing data pertaining to said leakage and said analysis results in a knowledge base; and
