# Dataset Card for QueryNER

QueryNER is a sequence labeling dataset for e-commerce query segmentation. 
It has 17 different entity types. QueryNER covers nearly the entire query rather than just certain key aspects that may be covered by other aspect-value extraction systems.


## Dataset Details

### Dataset Description

QueryNER is a manually-annotated dataset and accompanying model for e-commerce query segmentation. Prior work in sequence labeling for e-commerce has largely addressed aspect-value extraction which focuses
on extracting portions of a product title or query for narrowly defined aspects. Our work instead focuses on the goal
of dividing a query into meaningful chunks with broadly applicable types.
QueryNER has 17 different entity types. 

- **Repository:** [QueryNER](https://github.com/bltlab/query-ner)
- **Paper:** Accepted at LREC-COLING 2024, coming soon

- **Curated by:** BLT Lab
- **Language(s) (NLP):** English
- **License:** CC-BY 4.0

### Dataset Sources

QueryNER is annotation on a subsection of Amazon's [ESCI Shopping Queries dataset](https://github.com/amazon-science/esci-data). 

## Uses

QueryNER is intended to be used for segmentation of e-commerce queries in English. 

### Direct Use

QueryNER can be used for research on e-commerce query segmentation. 
It may also be used for e-commerce query segmentation for use in further downstream systems; however, we caution users that while the ontology is broadly applicable, using models trained on only this small public release may have suboptimal performance especially on out of domain data.

### Out-of-Scope Use

Users would likely experience poor segmentation performance on data outside of the e-commerce domain. 
Because the dataset is on the smaller side, additional annotated data on additional data using the QueryNER ontology
may be necessary to get better performance on other datasets.


## Dataset Structure

The dataset includes the query tokens and their tags. 


## Dataset Creation
See paper.

### Curation Rationale

The dataset was created for research and for downstream applications for e-commerce search systems to make use of segmented queries. 


### Source Data

The source data is from the Shopping Queries ESCI dataset. 
[https://github.com/amazon-science/esci-data](https://github.com/amazon-science/esci-data)


#### Data Collection and Processing

See paper


#### Who are the source data producers?

See source data repo and paper. 


### Annotations

#### Annotation process

See paper for details.

#### Who are the annotators?

Annotators were contract workers and were paid a living wage. 

#### Personal and Sensitive Information

The dataset is just user e-commerce queries and should not contain any sensitive information.


## Bias, Risks, and Limitations

The dataset is English only for now. 
Bias may be toward e-commerce queries of the source data. 
There may also be annotator bias since the dataset is annotated by a single annotator for the training set and three annotators and an adjudicator for the development and test sets.
