True Knowledge: Open-Domain Question Answering Using Structured Knowledge and Inference

  title={True Knowledge: Open-Domain Question Answering Using Structured Knowledge and Inference},
  author={William Tunstall-Pedoe},
  journal={AI Mag.},
This article gives a detailed description of True Knowledge: a commercial, open-domain question answering platform. The system combines a large and growing structured knowledge base of common sense, factual and lexical knowledge; a natural language translation system that turns user questions into internal language-independent queries and an inference system that can answer those queries using both directly represented and inferred knowledge. The system is live and answers millions of questions… Expand
A Survey of Question Answering over Knowledge Base
A survey of KBQA approaches is given by classifying them in two categories, and current mainstream techniques in KBZA are introduced, and similarities and differences among them are discussed. Expand
KBQA: Learning Question Answering over QA Corpora and Knowledge Bases
This paper designs a new kind of question representation: templates, over a billion scale knowledge base and a million scale QA corpora, and beats all other state-of-art works on both effectiveness and efficiency over QALD benchmarks. Expand
WikiQA — A question answering system on Wikipedia using freebase, DBpedia and Infobox
This work has implemented major components of a QA system which include challenging tasks of Named Entity Tagging, Question Classification, Information Retrieval and Answer Extraction, and has implemented an attributes mapping mechanism which is helpful to extract answer from data. Expand
Natural Language Question/Answering: Let Users Talk With The Knowledge Graph
This paper presents a data + oracle approach to answer NLQs over knowledge graphs and proposes a query prefetch technique that outperforms state-of-the-art methods in terms of both precision and recall. Expand
Using natural language processing for question answering in closed and open domains
A semantic-based QA system is presented which provides some experimental results over the closed and open domains and the efficiency of the ScoQAS is evaluated using measures such as precision, recall, and F-measure on LOD challenges in the open domain. Expand
Encyclopaedic question answering
A novel semantic architecture is proposed which represents a paradigm shift in open-domain QA system design, using semantic concepts and knowledge representation instead of words and information retrieval. Expand
A Natural Language Question Answering System as a Participant in Human Q&A Portals
A machine learning solution to the wrong answer avoidance (WAA) problem is presented, applying a meta classifier to the output of simple term-based classifiers and a rich set of other WAA features. Expand
Recent Trends in Natural Language Question Answering Systems: A Survey
The need to inquiry data content accessible in different organizations including organized and unstructured information has turned out to be progressively significant. Henceforth, Question AnsweringExpand
Functional Inferences over Heterogeneous Data
A rich inference framework (RIF) is developed that responds to queries where no suitable answer is readily contained in any available data source, by applying functional inferences over heterogeneous data from the web. Expand
Automated Reasoning Embedded in Question Answering
Modifications to ATP systems developed by the author are described, which allow the prover to fill gaps in the knowledge during the derivation, or to use external ontologies in other ways, for example for abductive reasoning. Expand
