Embodiment Construction

[0035] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0036] The general method for expanding the LIWC vocabulary is manual labeling. However, manual labeling is very time-consuming and labor-intensive, and requires language experts to add new words, which is not practical and efficient. In view of the above-mentioned problems, and facing the requirement of expanding and improving the LIWC vocabulary, the present invention proposes a method for automatically expanding the LIWC vocabulary.

[0037] figure 1 It is a schematic flow chart of a LIWC vocabulary expansion method according to a specific embodiment of the present invention, such as figure 1 As shown, a LIWC vocabulary expansion method includes: S1, applying an attention mechanism to construct the i-th level...

Abstract

The invention provides a method for expanding a LIWC vocabulary. The method includes steps S1 of applying an attention mechanism to construct an i-th layer context representation of a target word according to a semantic element of the target word and an i-1 layer label of the target word; step S2 of inputting the i-1 layer label, the i-th layer context representation and an i-1 layer hidden stateof a recurrent neural network, to acquire an i layer hidden state; step S3 of applying the i layer hidden state to acquire an i layer label of the target word; step S4 of repeating steps S1 to S3, andobtaining each layer of label of the target word layer by layer; wherein m>=i>=1, i is an integer, and m is the total layer number of the target word. According to the method for expanding the LIWC vocabulary, the LIWC vocabulary is automatically expanded based on the attention mechanism combined with the recurrent neural network of the semantic element, errors caused by artificial expansion areavoided, the accuracy of the LIWC vocabulary annotation is improved, and the labor costs and time costs are reduced.

Description

Technical field [0001] The invention relates to the technical field of language retrieval and word statistics vocabulary, in particular to a LIWC vocabulary expansion method. Background technique [0002] Language retrieval and word count (Linguistic Inquiry and Word Count, LIWC) is a natural language processing technology (Nature Language Processing, NLP), it can quantitatively analyze the text content and import different types of text files Whisper to calculate. The LIWC vocabulary manually divides words into detailed categories from coarse to fine. Due to its good reliability and validity, the LIWC vocabulary has been widely used in social sciences and other fields, such as experimental psychology, computational linguistics, and health. Diagnosis etc. [0003] Although LIWC has played a role in many fields, it only contains about 7000 words. As the most spoken language in the world, Chinese has more than 50,000 commonly used words. The currently marked LIWC vocabulary is far...
