A psycholinguistic italian dataset released with the paper <a href="https://arxiv.org/abs/2505.21301">How Humans and LLMs Organize Conceptual Knowledge: Exploring Subordinate Categories in Italian</a>. It contains a list of subordiante categories, or exemplars, for 187 concrete words or, basic-level categories.
## Dataset Creation
The dataset was created to study how Italian L1 speakers generate exemplars for common object categories. The stimuli consisted of 187 basic-level concrete categories (e.g., dog, table) organized under 12 superordinate semantic categories (e.g., animals, furniture).
An exemplar generation task was administered to 365 Italian L1 speakers. Participants were presented with a list of 15-16 categories and asked to produce as many exemplars as possible for each concept at their own pace.
The final human dataset, after cleaning and standardization, consists of 24,659 exemplars.
## Data Processing
Raw data underwent a post-processing step to correct common typos and misspellings. This was done to ensure the consistency and accuracy of the final dataset. The corrected exemplars were then standardized to a common format.
## Dataset Description
- **Curated by:** [ABSTRACTION-ERC Team](https://site.unibo.it/abstraction/it)
- **Curated by:** [AI4Text Group](https://hlt-isti.github.io/)
- **Language(s) (NLP):** Italian

## Dataset Structure
The dataset contains the aggregated results of the human experiment. For row in the dataset contains a unique subordinate exemplars and related statistics. The dataset contains the following columns:
1. `category`: the super-ordinate category
2. `concept`: the basic-level category
3. `exemplar`: the generated/produced sub-ordinate level exemplar/concept
4. `exemplar_string`: a sanitized version of the exemplar
5. `availability`: a metric which represents how readily the exemplar is produced as a member of its associated category
6. `count`: the number of occurrences of the exemplar across participants
7. `min_rank`: the minimum rank of exemplar's occurrence
8. `max_rank`: the highest rank of exemplar's occurrence
9. `mean_rank`: the average rank of exemplar's occurrence
10. `first_occur`: the ratio of exemplar occurring at first rank, divided by the total number of exemplar's occurrence
11. `dominance`: the proportion of participants who produce the exemplar given its associated category
12. `abs_freq_corpus`: only for LLM's generated exemplars, the number of exemplar's occurrences in the italian corpus `ItTenTen`
