Resumen
Abstract In this work we propose using word embeddings combined with unsupervised methods such as clustering for the multi-document summarization task of DUC (Document Understanding Conference) 2002. We aim to find evidence that semantic information is kept in word embeddings and this representation is subject to be grouped based on their similarity, so that main ideas can be identified in sets of documents. We experiment with different clustering methods to extract candidates for the multi-document summarization task. Our experiments show that our method is able to find the prevalent ideas. ROUGE measures of our experiments are similar to the state of the art, despite the fact that not all the main ideas are found; as our method does not require annotated resources, it provides a domain and language independent way to create a summary.
