A Semantic Analyzer for Emotion Recognition in Chinese: Enhancing Accuracy and Understanding

This paper presents a novel semantic analysis system aimed at recognizing emotions expressed in Chinese verbs. The SEEN system utilizes syntactic and morphological analysis based on Hidden Markov Models and statistical parsing methods. By examining 80 sentences, we achieved 100% accuracy in identifying semantic dependencies along with decision tree classification techniques. Our approach particularly focuses on distinguishing emotions "felt toward" and "felt by" entities, leading to improved recognition in natural language processing applications. The final system accuracy reaches 85.1% through rule-based corrections.

  1. A Semantic Analyzer for Aiding Emotion Recognition in Chinese ICIC 2006 Jiajun Yan, David B. Bracewell, Fuji Ren, and Shingo Kuroiwa. Department of Information Science and Intelligent Systems Faculty of Engineering, The University of Tokushima.

  2. Introduction • Semantic analysis helps to understand the roles and relations between objects, humans, etc. in the sentence. • In this paper, we propose a system for understanding emotion in Chinese verbs. • The emotion “felt toward” and “felt by” can be known.

  3. The SEEN System

  4. Syntactic Analysis • Morphological Analysis • Zhang, H., Yu, H., Xiong, D., Liu, Q.: Hhmm-based Chinese lexical analyzer ictclas.In: the Second SIGHAN workshop affiliated with 41st ACL. (2003) • Based on Hidden Markov Model • Chinese Parsing • Zhou, Q.: A statistics-based Chinese parser. In: Proceedings of the Fifth Workshop on Very Large Corpora. (1997) • Because the parser was used on the Penn Chinese Treebank, and it is freely available

  9. Semantic Dependency Assignment • Decision Tree Classifier • 4 Features • Phrase Type • Headword & Dependent • Headword & DependentPart-of-Speech • Context • Accuracy 84%

  10. Chinese Emotion Predicates

  11. Chinese Emotion Predicates

  12. Experimentation • 80 sentences (10 sentences per predicate) were collected and examined. • Negated emotions in English are not looked at. The semantic dependency was manually given. • The accuracy was 100%.

  13. Experimentation • Example of a Currently Unclassifiable Sentence

  14. SEEN System (After) • DT Classifier -> Probabilistic Classification • Add Rule-Based Correction • Accuracy increase to 85.1%
