BERTAUT v1

English Version

BERTAUT v1 is a BERT-based text classification model for early UTAUT-related category detection and text filtering. The model classifies user-generated text, user reviews, open-ended questionnaire responses, public comments, and other unstructured technology-related text.

Created by Teguh Arie Sandy.

Label Definitions

PE: Performance Expectancy

Text expressing perceived usefulness, benefits, productivity, effectiveness, or performance improvement gained from technology use.

Example: This application helps me complete my tasks faster.

EE: Effort Expectancy

Text expressing ease of use, difficulty, simplicity, complexity, or the effort required to use a technology.

Example: The application is easy to use and the menu is clear.

SI: Social Influence

Text expressing influence from friends, family, lecturers, colleagues, communities, ratings, reviews, public figures, or other users.

Example: I use this application because my friend recommended it.

FC: Facilitating Conditions

Text expressing supporting conditions such as internet access, devices, system support, infrastructure, login access, server quality, or technical assistance.

Example: The application works well because my internet connection is stable.

GR: Generic Review

Short and general review text that does not clearly indicate PE, EE, SI, or FC.

Example: Good.

SP: Spam

Spam, promotional text, advertisements, irrelevant links, gambling content, or unrelated commercial messages.

Example: Register now and get a big bonus today.

—Early classification of technology acceptance text in Indonesian and other languages covered by mBERT, subject to validation on the target domain.
—Analysis of user reviews and public comments.
—Categorization of open-ended questionnaire responses.
—Automated text labeling before manual review.
—Identification of generic reviews and spam content.

Limitations

This is a seed model. The training dataset is still limited and may be improved with additional independently labeled data in future versions. Model performance can vary across languages and domains that differ from the training data.

The BI, Behavioral Intention, label is not included in this v1 release because the seed dataset does not yet contain sufficient BI examples.

Future development may include:

—BI: Behavioral Intention.
—AU: Actual Use.
—Multi-label classification.
—Sentiment-aware UTAUT classification.
—Larger balanced datasets.
—More multilingual training data.

Keterbatasan

Model ini merupakan seed model. Dataset pelatihan masih terbatas dan dapat ditingkatkan dengan penambahan data yang diberi label secara independen pada versi berikutnya. Performa model dapat berbeda pada bahasa dan domain yang tidak serupa dengan data pelatihan.

Label BI, Behavioral Intention, belum dimasukkan pada rilis v1 karena dataset seed belum memiliki contoh BI dalam jumlah cukup.

Pengembangan berikutnya dapat mencakup:

—BI: Behavioral Intention.
—AU: Actual Use.
—Klasifikasi multi-label.
—Klasifikasi UTAUT berbasis sentimen.
—Dataset seimbang dengan jumlah data lebih besar.
—Data pelatihan multibahasa yang lebih luas.
