Welcome to ROCLING 2021!

ROCLING 2021 is the 33rd annual Conference on Computational Linguistics and Speech Processing in Taiwan sponsored by the Association for Computational Linguistics and Chinese Language Processing (ACLCLP).The conference will be held in the Teaching and Research Building of National Central University (NCU) in Taoyuan, Taiwan during October 15-16, 2021.

ROCLING 2021 will provide an international forum for researchers and industry practitioners to share their new ideas, original research results and practical development experiences from all language and speech research areas, including computational linguistics, information understanding, and signal processing. ROCLING 2021 will feature oral papers, posters, tutorials, special sessions and shared tasks.

The conference on Computational Linguistics and Speech Processing (ROCLING) was initiated in 1988 by the Association for Computational Linguistics and Chinese Language Processing (ACLCLP) with the major goal to provide a platform for researchers and professionals from around the world to share their experiences related to natural language processing and speech processing. Following are a list of past ROCLING conferences.

Call for Papers

ROCLING 2021 invites paper submissions reporting original research results and system development experiences as well as real-world applications. Each submission will be reviewed based on originality, significance, technical soundness, and relevance to the conference. Accepted papers will be presented orally or as poster presentations. Both oral and poster presentations will be published in the ROCLING 2021 conference proceedings and included in the ACL Anthology. A number of papers will be selected and invited for extension into journal versions and publication in a special issue of the International Journal of Computational Linguistics and Chinese Language Processing (IJCLCLP).

Papers can be written and presented in either Chinese or English. Papers should be made in PDF format and submitted online through the paper submission system. Submitted papers may consist of 4-8 pages of content, plus unlimited references. Upon acceptance, final versions will be given additional pages of content (up to 9 pages) so that reviewers’ comments can be taken into account. ROCLING 2021 mainly targets two scientific tracks: natural language processing (NLP) and speech processing (Speech). Relevant topics for the conference include, but are not limited to, the following areas (in alphabetical order):

Neurolinguistic is an interdisciplinary study that incorporates elements of neuroscience, linguistics, computational science, and cognitive psychology to aiming to explore how the brain processes human language. By presenting our research results to the science community, we hope to encourage future studies from researchers and graduate students in the areas of computational science and linguistics. The speech parameters mentioned in this symposium were gathered from distinct sources including Sinica Corpus and COSPRO & Toolkit published by the Association for Computational Linguistics and Chinese Language Processing, and customized databases that were built by researchers regarding their purposes of research. These data are beneficial to research studies aiming to explore topics in language development and language comprehension in native speakers. Dr. Chun-Hsien Hsu is going to introduce some basic research methods in cognitive neuroscience, and the research results of using Magnetoencephalography (MEG) to study morphosyntactic theories and speech comprehension. Dr. Hsu would also shares some approaches to employ deep learning models for studying the features of brain responses to language. Dr. Chia-yin Lee is going to talk about the use of combining behavioral testings and Event-Related Potential (ERP) in vocabulary knowledge and language development studies. Dr. Lee intends to clarify common misconceptions and myths about Chinese orthography and phonetic structures, and explain the current changes/shift in theories of mental lexicon through corpus analyses. Dr. Chia-Lin Lee is going to share with us about the cognitive functions and brain mechanisms involved in the processing of meaningful information, which includes the fetching of appropriate semantic meaning depending on the context of usage ( i.e. the concept of “piano” may comprise the sound of a piano, the shape of the instrument, and different ways to play it etc.), and the effect of aging on general cognitive function and semantic processes.

ROCLING 2021 Shared Task:

Dimensional Sentiment Analysis for Educational Texts


I. Background

Sentiment analysis has emerged as a leading technique to automatically identify affective information within texts. In sentiment analysis, affective states are generally represented using either categorical or dimensional approaches (Calvo and Kim, 2013). The categorical approach represents affective states as several discrete classes (e.g., positive, negative, neutral), while the dimensional approach represents affective states as continuous numerical values on multiple dimensions, such as valence-arousal (VA) space (Russell, 1980), as shown in Fig. 1. The valence represents the degree of pleasant and unpleasant (or positive and negative) feelings, and the arousal represents the degree of excitement and calm. Based on this two-dimensional representation, any affective state can be represented as a point in the VA coordinate plane by determining the degrees of valence and arousal of given words (Wei et al., 2011; Malandrakis et al., 2013; Wang et al., 2016; Du and Zhang, 2016; Wu et la., 2017; Yu et al., 2020) or texts (Kim et al., 2010; Paltoglou et al, 2013; Goel et la., 2017; Zhu et al., 2019; Wang et al., 2019; 2020).

In 2016, we hosted a first dimensional sentiment analysis task for Chinese words (Yu et al., 2016b) at the 20th International Conference on Asian Language Processing (IALP 2016). In 2017, we extended this task to include both word- and phrase-level dimensional sentiment analysis (Yu et al., 2017). This year, we explore the sentence-level dimensional sentiment analysis task on educational texts (students’ self-evaluated comments).

II. Task Description

Structured data such as attendance, homework completion and in-class participation have been extensively studied to predict students’ learning performance. Unstructured data, such as self- evaluation comments written by students, is also a useful data resource because it contains rich emotional information that can help illuminate the emotional states of students (Yu et al., 2018). Dimensional sentiment analysis is an effective technique to recognize the valence-arousal ratings from texts, indicating the degree from most negative to most positive for valence, and from most neutral low Valence IV Low-Arousal, Positive-Valence Tired calm to most excited for arousal.

In this task, participants are asked to provide a real-valued score from 1 to 9 for both valence and arousal dimensions for each self-evaluation comment. The input format is “sentence_id, sentence”, and the output format is “sentence_id, vallence_rating, arousal_rating”. Below are the input/output formats of the example sentences.

Example 1:

     Input: 1, 今天教了許多以前沒有學過的東西,所以上起課來很新鮮

     Output: 1, 6.8, 5.2

Example 2:

     Input: 2, 覺得課程進度有點快,內容難以消化

     Output: 2, 3.0, 4.0

III. Data

Training set

  • CVAW 4.0 : including 5,512 single words annotated with valence-arousal ratings (Yu et al., 2016a).
  • CVAP 2.0 : including 2,998 multi-word phrases annotated with valence-arousal ratings (Yu et al., 2017)
  • CVAT 2.0 : including 2,969 sentences annotated with valence-arousal ratings (Yu et al., 2016a).

The policy of this shared task is an open test. Participating systems are allowed to use other publicly available data for this shared task, but the use of other data should be specified in the final technical report.

IV. Evaluation

The performance is evaluated by examining the difference between machine-predicted ratings and human-annotated ratings (valence and arousal are treated independently). The evaluation metrics include:

Mean absolute error:

Pearson correlation coefficient:

where Ai denotes the human-annotated ratings, Pi denotes the machine-predicted ratings, n is the number of test samples, A and P respectively denote the arithmetic mean of A and P, and σ is the standard deviation.
