Abstract

An approach is provided for generating actionable content ingestion recommendations based on an interaction history that is mined to extract interaction context parameters from questions and answer results that meet specified answer deficiency criteria by searching one or more content sources using the extracted interaction context parameters to identify new content that is relevant to improving the first answer, and then presenting the new content in an actionable content ingestion recommendation list for display and review by a domain expert, where the actionable content ingestion recommendation fist recommends the new content for ingestion in a knowledge base corpus.

First claim

1 - 11 . (canceled)

12 . An information handling system comprising:
one or more processors; a memory coupled to at least one of the processors; a set of instructions stored in the memory and executed by at least one of the processors to generate actionable content ingestion recommendations, wherein the set of instructions perform actions of: mining, by the system, an interaction history comprising a plurality of questions and answer results for a plurality of users to extract interaction context parameters for at least a first answer that meets specified answer deficiency criteria; searching, by the system, one or more content sources using the extracted interaction context parameters along with multi-factorial variable or attributes about the users to identify new content that is relevant to improving the first answer or adding new answers to a candidate answer list; and presenting, by the system, an actionable content ingestion recommendation for display and review by a domain expert, where the actionable content ingestion recommendation lists the new content for ingestion in a knowledge base corpus.

13 . The information handling system of claim 12 , where mining the interaction history comprises performing, by the system, a natural language processing (NLP) analysis of each question and answer in the interaction history, where the NLP analysis at least extracts key terms, question sentiment, question focus, N-grams, lexical answer type information, a first user location, and time information for each question submitted corresponding to the first answer.

14 . The information handling system of claim 12 , where mining the interaction history comprises performing, by the system, an association analysis of each question and answer in the interaction history to identify one or more questions and associated comments that are similar to a first question corresponding to the first answer.

15 . The information handling system of claim 12 , where mining the interaction history comprises filtering, by the system, the extracted interaction context parameters using a multifactorial topical model, such as a Latent Dirichlet Allocation (LDA) or Latent Semantic Analysis (LSA) model.

16 . The information handling system of claim 12 , where searching one or more content sources comprises using the extracted interaction context parameters to search against a document repository, enterprise content management (ECM) system, knowledge management system (KMS), or cloud-based document repository.

17 . A computer program product stored in a computer readable storage medium, comprising computer instructions that, when executed by an information handling system, causes the system to generate actionable content ingestion recommendations by performing actions comprising:
mining, by the system, an interaction history comprising a plurality of questions and answer results for a plurality of users to extract interaction context parameters for at least a first answer that meets specified answer deficiency criteria; searching, by the system, one or more content sources using the extracted interaction context parameters along with multi-factorial variable or attributes about the users to identify new content that is relevant to improving the first answer or adding new answers to a candidate answer list; and presenting, by the system, an actionable content ingestion recommendation for display and review by a domain expert, where the actionable content ingestion recommendation lists the new content for ingestion in a knowledge base corpus.

18 . The computer program product of claim 17 , where mining the interaction history comprises performing, by the system, a natural language processing (NLP) analysis of each question and answer in the interaction history, where the NLP analysis at least extracts key terms, question sentiment, question focus, N-grams, lexical answer type information, a first user location, and time information for each question submitted corresponding to the first answer.

19 . The computer program product of claim 17 , where mining the interaction history comprises performing, by the system, an association analysis of each question and answer in the interaction history to identify one or more questions and associated comments that are similar to a first question corresponding to the first answer.

20 . The computer program product of claim 17 , where mining the interaction history comprises filtering, by the system, the extracted interaction context parameters using a multifactorial topical model, such as a Latent Dirichlet Allocation (LDA) or Latent Semantic Analysis (LSA) model.

21 . The computer program product of claim 17 , where searching one or more content sources comprises using the extracted interaction context parameters to search against a document repository, enterprise content management (ECM) system, knowledge management system (KMS), or cloud-based document repository.
