Introduced by du Toit and Dunaiski (2024) [Introducing Three New Benchmark Datasets for Hierarchical Text Classification](https://arxiv.org/abs/2411.19119). |
|
|
|
|
|
The WOS Hierarchical Text Classification are three dataset variants created from Web of Science (WOS) title and abstract data categorised into a hierarchical, multi-label class structure. The aim of the sampling and filtering methodology used was to create well-balanced class distributions (at chosen hierarchical levels). Furthermore, the WOS_JTF variant was also created with the aim to only contain publication data such that their class assignments results is classes instances that semantically more similar. |
|
|
|
|
|
|
|
|
The three dataset variants have the following properties: |
|
|
1. WOS_JT comprises 43,366 total samples (train=30356, dev=6505, test=6505) and only uses the journal-based classifications as labels. |
|
|
2. WOS_CT comprises 65,200 total samples (train=45640, dev=9780, test=9780) and only uses citation-based classifications as labels. |
|
|
3. WOS_JTF comprises 42,926 total samples (train=30048, dev=6439, test=6439) and uses a filtered set of papers based on journal and citation classification. |

Dataset details: |
|
|
|
|
|
*.json: |
|
|
- concatenated title and abstract mapped to a list each associated class label. |
|
|
|
|
|
depth2label.pt: dictionary where: |
|
|
- key = depth of classification hierarchy. |
|
|
- value = list of classes associated with depth. |
|
|
|
|
|
path_list.pt: |
|
|
- list of tuples for every edge between classes in the hierarchical classification. This specifies the acyclic graph. |
|
|
|
|
|
slot.pt: dictionary where: |
|
|
- key = label_id of parent class. |
|
|
- value = label_ids of children classes. |
|
|
|
|
|
value2slot.pt: dictionary where: |
|
|
- key = label_id. |
|
|
- value = label_id of parent class. |
|
|
|
|
|
value_dict.pt: dictionary where: |
|
|
- key = label_id. |
|
|
- value = string representation of class. |
