Problems solved by technology

[0006] The template rule matching method is better for a small amount of semantic processing, but the gradual increase in the corpus will cause intention conflicts, chaotic sentence patterns, and unclear levels, which are difficult to maintain
The model trained by the machine learning method has domain adaptability to the labeled domain, but lacks the pan-domain capability. For new domain semantics, it needs to be re-labeled and trained to recognize

Embodiment 1

[0040] In order to solve the above-mentioned technical problems existing in the prior art, an embodiment of the present invention provides a method for understanding spoken language semantics.

[0041] The inventors found that colloquial short texts usually do not follow grammatical rules, are short in length, do not have enough information for statistical inference, and are difficult to make accurate inferences in a limited context. For example: the syntax structure can be arranged in any order, "the air conditioner is turned on" means the intention to turn on the air conditioner, and "is the air conditioner turned on" means to query the state of the air conditioner.

[0042] Embodiments of the present invention combine rule-based matching and machine learning for colloquial short texts:

[0043] Train text classification models and entity extraction models on the basis of existing label data to achieve semantic understanding in existing fields;

[0044] For semantic underst...

Embodiment 2

[0096] The embodiment of the present invention also provides a spoken language semantic understanding device, which includes:

[0097] A text classification unit, configured to perform text classification processing on the input spoken text based on the text classification model, to obtain the corresponding domain and intent of the spoken text;

[0098] An entity extraction unit, configured to perform entity extraction processing on the input spoken text based on the entity extraction model, to obtain entity parameters corresponding to the spoken text;

[0099] a scoring unit, configured to score the accuracy of the text classification process and the entity extraction process, and obtain a score value;

[0100] An output judging unit, configured to output structured information according to the domain, the intention and the entity parameter when the scoring value is greater than or equal to a preset scoring threshold.

[0101] The embodiment of the present invention also pro...

Abstract

The invention provides a spoken language semantic comprehension method, device and system, and the method comprises the steps: carrying out the text classification of an inputted spoken language textbased on a text classification model, and obtaining a field and an intention corresponding to the spoken language text; performing entity extraction processing on the input spoken language text basedon an entity extraction model to obtain entity parameters corresponding to the spoken language text; scoring the accuracy of the text classification processing and the entity extraction processing toobtain a score value; and when the score value is greater than or equal to a preset score threshold, outputting structured information according to the domain, the intention and the entity parameters.According to the method, rule matching and a machine learning model are combined, on the basis of rapid and accurate recognition of spoken language semantics, matching and label setting of new fielddata are completed, and understanding of the new field spoken language data is achieved.

Description

technical field [0001] The invention belongs to the field of intelligent control, and in particular relates to a spoken language semantic understanding method, device and system. Background technique [0002] In the field of voice interaction, converting natural language into semantics that machines can understand is the core technical content. Semantics not only expresses the essence of things, but also expresses various logical relationships between things, such as causality, subordination, and facts. Semantic analysis and understanding is to identify the semantics contained in information and establish a model to make it understand related texts, among which Semantic understanding is inseparable from technologies such as rule matching, text classification, entity recognition and extraction. [0003] The current semantic understanding technology is mainly divided into two types: [0004] (1) Template rule matching method: Accurate matching is performed by setting spoken ...
