Abstract
Embodiments of the present invention provide an approach for automatically assigning a confidence level to information extracted from a transcription of a voice recording. Specifically, in a typical embodiment, an axiom is extracted from a source associated with the text of the transcription. A confidence level of the source is determined. A confidence level is assigned to the axiom based on the confidence level of the source.
Claims18
A method of assigning a confidence level to an axiom extracted from a text of a transcription of a voice recording;
- receiving, at a computer device, the text of the transcription;
- comparing, using the computer device, every word from the text to a customer specific dictionary and a dictionary of common language words;
- determining a number of inaccurately spelled words in the transcription based on the comparing;
- assigning, using a Gaussian distribution, a confidence level to the text of the transcription based on the determining;
- estimating an accuracy of the text based on the assigned confidence level;
- gathering, using the computer device, external information related to words in the text by retrieving a set of axioms that further define the words in the text of the transcription from a set of sources, each axiom in the set of axioms comprising a proposition that is regarded as being at least one of established, accepted, and self-evidently true;
- determining a confidence level of each source of the set of sources;
- and
- assigning a confidence level to each axiom of the set of axioms based on a combination of the confidence level of the set of sources and the accuracy of the text estimated based on the assigned confidence level.
A system for assigning a confidence level to an axiom extracted from a text of a transcription of a voice recording, comprising:
- a memory medium comprising instructions;
- a bus coupled to the memory medium;
- and
- an audio transcription tool coupled to the bus that when executing the instructions causes the system to:
- receive the text of the transcription;
- compare every word from the text to a customer specific dictionary and a dictionary of common language words;
- determine a number of inaccurately spelled words in the transcription based on the comparing;
- assign, using a Gaussian distribution, a confidence level to the text of the transcription based on the determining;
- estimate an accuracy of the text based on the assigned confidence level;
- gather external information related to words in the text by retrieving a set of axioms that further define the words in the text of the transcription from a set of sources, each axiom in the set of axioms comprising a proposition that is regarded as being at least one of established, accepted, and self-evidently true;
- determine a confidence level of each source of the set of sources;
- and
- assign a confidence level to each axiom of the set of axioms based on a combination of the confidence level of the set of sources and the accuracy of the text estimated based on the assigned confidence level.
A computer program product for assigning a confidence level to an axiom extracted from a text of a transcription of a voice recording, the computer program product comprising a non-transitory computer readable storage medium, and program instructions stored on the non-transitory computer readable storage medium, to:
- receive the text of the transcription;
- compare every word from the text to a customer specific dictionary and a dictionary of common language words;
- determine a number of inaccurately spelled words in the transcription based on the comparing;
- assign, using a Gaussian distribution, a confidence level to the text of the transcription based on the determining;
- estimate an accuracy of the text based on the assigned confidence level;
- gather external information related to words in the text by retrieving a set of axioms that further define the words in the text of the transcription from a set of sources, each axiom in the set of axioms comprising a proposition that is regarded as being at least one of established, accepted, and self-evidently true;
- determine a confidence level of each source of the set of sources;
- and
- assign a confidence level to each axiom of the set of axioms based on a combination of the confidence level of the set of sources and the accuracy of the text estimated based on the assigned confidence level.
A method for deploying a system for assigning a confidence level to an axiom extracted from a text of a transcription of a voice recording, comprising:
- providing a computer infrastructure being operable to:
- receive, at a computer device, the text of the transcription;
- compare, using the computer device, every word from the text to a customer specific dictionary and a dictionary of common language words;
- determine a number of inaccurately spelled words in the transcription based on the comparing;
- assign, using a Gaussian distribution, a confidence level to the text of the transcription based on the determining;
- estimate an accuracy of the text based on the assigned confidence level;
- gather, using the computer device, external information related to words in the text by retrieving a set of axioms that further define the words in the text of the transcription from a set of sources, each axiom in the set of axioms comprising a proposition that is regarded as being at least one of established, accepted, and self-evidently true;
- determine a confidence level of each source of the set of sources;
- and
- assign a confidence level to each axiom of the set of axioms based on a combination of the confidence level of the set of sources and the accuracy of the text estimated based on the assigned confidence level.
