QUESTION ANSWERING FROM STRUCTURED AND UNSTRUCTURED DATA SOURCES |
| 摘要 |
Techniques for question answering involve receiving, from a user, a text input expressing a question in natural language. The text input may be analyzed, including identifying in the question at least one first portion answerable from at least one structured data source, and at least one second portion answerable from at least one unstructured data source. At least one first query configured for the structured data source(s) may be constructed from the at least one first portion of the question and applied to the structured data source(s) to retrieve first answer information for the at least one first portion of the question. At least one second query configured for the unstructured data source(s) may be constructed from the at least one second portion of the question and applied to the unstructured data source(s) to retrieve second answer information for the at least one second portion of the question. |

1. A method comprising:
receiving, from a user, a text input expressing a question in natural language; analyzing the text input, using an analysis component implemented via at least one processor, the analyzing comprising identifying in the question at least one first portion answerable from at least one structured data source, and at least one second portion answerable from at least one unstructured data source; constructing, from the at least one first portion of the question, at least one first query configured for the at least one structured data source, and applying the at least one first query to the at least one structured data source to retrieve first answer information for the at least one first portion of the question; and constructing, from the at least one second portion of the question, at least one second query configured for the at least one unstructured data source, and applying the at least one second query to the at least one unstructured data source to retrieve second answer information for the at least one second portion of the question. |
