This task is important in order to\nunderstand short reviews majority of the users write, while existing topic\nmodels are targeted for expert-level long reviews with sufficient co-occurrence\npatterns to observe. Current methods on aggregating micro reviews using\nmetadata information may not be effective as well due to metadata absence,\ntopical heterogeneity, and cold start problems. To this end, we propose a model\ncalled Micro Aspect Sentiment Model (MicroASM). MicroASM is based on the\nobservation that short reviews 1) are viewed with sentiment-aspect word pairs\nas building blocks of information, and 2) can be clustered into larger reviews.\nWhen compared to the current state-of-the-art aspect sentiment models,\nexperiments show that our model provides better performance on aspect-level\ntasks such as aspect term extraction and document-level tasks such as sentiment\nclassification.","url_abs":"http://arxiv.org/abs/1806.05499v1","url_pdf":"http://arxiv.org/pdf/1806.05499v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"aspect-sentiment-model-for-micro-reviews","repo_url":"https://github.com/rktamplayo/MicroASM","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"aspect-based-sentiment-analysis-1","task_name":"Aspect-Based Sentiment Analysis"},{"task_slug":"aspect-based-sentiment-analysis","task_name":"Aspect-Based Sentiment Analysis (ABSA)"},{"task_slug":"sentiment-analysis","task_name":"Sentiment Analysis"},{"task_slug":"sentiment-classification","task_name":"Sentiment Classification"},{"task_slug":"term-extraction","task_name":"Term Extraction"},{"task_slug":"topic-models","task_name":"Topic Models"},{"task_slug":"model","task_name":"model"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
