Code and dataset for ACL2019 [paper] ‘‘An Interactive Multi-Task Learning Network for End-to-End Aspect-Based Sentiment Analysis’’.

The preprocessed aspect-level datasets can be downloaded at [Download], and the document-level datasets can be downloaded at [Download]. The zip files should be decompressed and put in the main folder.

Glove vectors (glove.840B.300d) are used for initialization of general word embeddings. Pre-trained word embeddings from [Hu et al.] are used for initialization of domain-specific word embeddings. To save the time of reading large files, subsets of the pre-trained vectors are extracted which only contain the words that belong to the vocab for each dataset. You can download the extracted files for glove vectors and domain-specific vectors at [Download] and [Download] respectively. The zip files should be decompressed and put in the main folder.

Excute the command below for training and evaluating IMN.

CUDA_VISIBLE_DEVICES="0" python train.py --domain $domain

where $domain in ['res', 'lt', 'res_15'] denotes the corresponding aspect-level dataset. You can find all arguments defined in train.py with default values used in our experiments. At the end of each epoch, evaluation results on validation and test sets are saved in out.log. The test results at the epoch where the model achieves the best performance on validation set are recorded.
