Aspect term extraction via information-augmented neural network

open access: yesComplex & Intelligent Systems, 2022
Aspect term extraction (ATE) aims at identifying the aspect terms that are expressed in a sentence. Recently, Seq2Seq learning has been employed in ATE and significantly improved performance.

DLIREC: Aspect Term Extraction and Term Polarity Classification System [PDF]

open access: goldProceedings of the 8th International Workshop on Semantic Evaluation (SemEval 2014), 2014
This paper describes our system used in the Aspect Based Sentiment Analysis Task 4 at the SemEval-2014. Our system consists of two components to address two of the subtasks respectively: a Conditional Random Field (CRF) based classifier for Aspect Term Extraction (ATE) and a linear classifier for Aspect Term Polarity Classification (ATP).

BeeAE: effective aspect term extraction with artificial bee colony [PDF]

open access: hybridThe Journal of Supercomputing, 2022
AbstractAspect terms are opinion targets for people to express and understand opinions in reviews. Aspect terms extraction is an essential subtask in aspect-level sentiment analysis. To extract aspect terms from a sentence, existing methods mainly focus on context features generated by pre-trained models.

Constituency Lattice Encoding for Aspect Term Extraction

open access: goldProceedings of the 28th International Conference on Computational Linguistics, 2020
One of the remaining challenges for aspect term extraction in sentiment analysis resides in the extraction of phrase-level aspect terms, which is non-trivial to determine the boundaries of such terms. In this paper, we aim to address this issue by incorporating the span annotations of constituents of a sentence to leverage the syntactic information in ...

Bridge-Based Active Domain Adaptation for Aspect Term Extraction [PDF]

open access: goldProceedings of the 59th Annual Meeting of the Association for Computational Linguistics and the 11th International Joint Conference on Natural Language Processing (Volume 1: Long Papers), 2021
As a fine-grained task, the annotation cost of aspect term extraction is extremely high. Recent attempts alleviate this issue using domain adaptation that transfers common knowledge across domains. Since most aspect terms are domain-specific, they cannot be transferred directly. Existing methods solve this problem by associating aspect terms with pivot

Improving Aspect Term Extraction with Bidirectional Dependency Tree Representation [PDF]

open access: greenIEEE/ACM Transactions on Audio, Speech, and Language Processing, 2018
Aspect term extraction is one of the important subtasks in aspect-based sentiment analysis. Previous studies have shown that using dependency tree structure representation is promising for this task. However, most dependency tree structures involve only one directional propagation on the dependency tree.
