## Dataset Summary

A dataset for training and evaluating models in aspect-based sentiment analysis. It contains student reviews of academic courses written in Russian.


## Dataset Structure

### Data Fields

**Input**

* `text`: review text

**Output** — sentiment labels for each aspect, the aspect is described in the column name:

* `лекции`
* `доклады`
* `проекты`
* `презентации`
* `фильмы`
* `видео-уроки`
* `задания__задачи`
* `онлайн-курс`
* `баллы__оценки`
* `практики__семинары`
* `тесты`
* `домашняя работа`

* `3`: negative

### Data Splits

The dataset is split into three parts:

* train
* validation
* test

Random split in proportions: 0.8 / 0.1 / 0.1

## Dataset Creation

### Curation Rationale

This dataset was created for training aspect-based sentiment analysis models on course review data. Traditional sentiment analysis lacked the granularity needed for educational analytics.

### Source Data

#### Initial Data Collection and Normalization

Reviews were collected from the website: [https://electives.utmn.ru](https://electives.utmn.ru)
On this platform, students from Tyumen State University leave feedback on elective courses they have taken.
All reviews available as of May 6, 2024 were collected. Nonsensical or off-topic reviews were excluded.

#### Who are the source language producers?

The reviews were written by undergraduate students (typically aged 18–21, though not strictly limited to this range).

### Annotations

#### Annotation process

Aspects were identified using keyword searches across the review corpus. Relevant keywords and synonyms were grouped into unified aspects. Each aspect was assigned one of the sentiment classes based on the following:

* **Positive**: a positive opinion expressed
* **Neutral**: the aspect is mentioned, but no clear opinion or a mixed one is expressed
* **Negative**: a negative opinion is expressed
* **Absent**: the aspect is not mentioned

Annotation was done by two annotators, each labeling half of the dataset. There was no cross-annotation, but difficult cases were discussed jointly and resolved with a final verdict.

#### Who are the annotators?

The annotators were two students from Tyumen State University.

### Personal and Sensitive Information

No personal information (such as name, faculty, or program) is included in the dataset.

## Considerations for Using the Data

### Social Impact of Dataset

A model trained on this dataset can automatically extract insights into student opinions on the learning process, enabling data-driven decision-making in educational contexts.

### Other Known Limitations

* The dataset may not be large enough for robust training.
* Some aspects are underrepresented.
* Additional data or augmentation may be required.
* It may be better to use stratified splits instead of random ones.
