The invention provides a compound word representation learning method and device. The compound word representation learning method comprises the steps: learning basic vector representation of each component in a compound word and vector representation of each meaning of each component; for any one of the components, obtaining a synonym enhancement vector representation of the component based on amutual attention mechanism according to the vector representation of each synonym of the component and the basic vector representation of other components except the component in the compound word; and obtaining a final vector representation of the compound word according to the basic vector representations of all the components in the compound word and the synonym enhancement vector representations of all the components. According to the compound word representation learning method, the representation of the compound words contains semantic features of finer granularity of all components of the compound words, and the effect of downstream application of the compound words is improved, and the compound word representation learning method has good practicability.
Description
technical field [0001] The invention belongs to the technical field of natural language processing, and in particular relates to a compound word representation learning method and device. Background technique [0002] In linguistics, semantic composition refers to the phenomenon that the semantics of a compound language unit is composed of the semantics of its constituents, which is considered by many linguists to be a fundamental fact of semantics. Semantic composition has important applications in many natural language processing tasks, such as language models and sentiment analysis. [0003] Representation learning for compound words is a major research problem in semantic composition, especially for bimorphic compound words. Existing compound word representation learning methods focus on using more complex combination functions for modeling. In fact, external linguistic knowledge, such as sememe knowledge, can also be introduced into the semantic composition model to im...
