Inferring logical clauses for answering complex multi-hop open domain questions

A computing device configured to generate an automated answer to a complex query, the computing device comprising:

• a computer-readable medium storing non-transitory computer-executable program instructions;
• and
• a processing device communicatively coupled to the computer-readable medium for executing the non-transitory computer-executable program instructions, wherein executing the non-transitory computer-executable program instructions with the processing device causes the computing device to perform operations comprising:
• obtaining a user query comprising the complex query, the complex query comprising a plurality of search parameters;
• identifying a first simple query of the complex query and a second simple query of the complex query, the first simple query comprising a first search parameter of the plurality of search parameters, the second simple query comprising a second search parameter of the plurality of search parameters, wherein identifying the first simple query and the second simple query includes:
• i) generating an abstract meaning representation for the user query to identify the first simple query and the second simple query, or ii) generating a discourse tree for the user query to identify the first simple query and the second simple query;
• obtaining a first set of search results based at least in part on executing the first simple query utilizing a search engine;
• identifying a first common term of the first set of search results;
• executing, utilizing the search engine, the second simple query with the first common term identified from the first set of search results, wherein a second set of search results are obtained based at least in part on executing the second simple query with the first common term;
• identifying a second common term of the second set of search results;
• and
• generating the automated answer to the complex query based at least in part on the first common term and the second common term.

A non-transitory computer-readable storage medium storing computer-executable program instructions for generating an automated answer to a complex query, wherein when executed by a processing device, the computer-executable program instructions cause the processing device to perform operations comprising:

• obtaining a user query comprising the complex query, the complex query comprising a plurality of search parameters;
• identifying a first simple query of the complex query and a second simple query of the complex query, the first simple query comprising a first search parameter of the plurality of search parameters, the second simple query comprising a second search parameter of the plurality of search parameters, wherein identifying the first simple query and the second simple query includes:
• i) generating an abstract meaning representation for the user query to identify the first simple query and the second simple query, or ii) generating a discourse tree for the user query to identify the first simple query and the second simple query;
• obtaining a first set of search results based at least in part on executing the first simple query utilizing a search engine;
• identifying a first common term of the first set of search results;
• executing, utilizing the search engine, the second simple query with the first common term identified from the first set of search results, wherein a second set of search results are obtained based at least in part on executing the second simple query with the first common term;
• identifying a second common term of the second set of search results;
• and
• generating the automated answer to the complex query based at least in part on the first common term and the second common term.
