A data-driven strategy to combine word embeddings in information retrieval

2021-05-26 · Alfredo Silva, Marcelo Mendoza

Word embeddings are vital descriptors of words in unigram representations of documents for many tasks in natural language processing and information retrieval. The representation of queries has been one of the most critical challenges in this area because it consists of a few terms and has little descriptive capacity. Strategies such as average word embeddings can enrich the queries' descriptive capacity since they favor the identification of related terms from the continuous vector representations that characterize these approaches. We propose a data-driven strategy to combine word embeddings. We use Idf combinations of embeddings to represent queries, showing that these representations outperform the average word embeddings recently proposed in the literature. Experimental results on benchmark data show that our proposal performs well, suggesting that data-driven combinations of word embeddings are a promising line of research in ad-hoc information retrieval.

The Unreasonable Effectiveness of Random Target Embeddings for Continuous-Output Neural Machine Translation

2023-10-31 · Evgeniia Tokarchuk, Vlad Niculae

Continuous-output neural machine translation (CoNMT) replaces the discrete next-word prediction problem with an embedding prediction. The semantic structure of the target embedding space (i.e., closeness of related words…

Beyond Bilingual: Multi-sense Word Embeddings using Multilingual Context

2017-06-25 · WS 2017 8 · Shyam Upadhyay, Kai-Wei Chang, Matt Taddy, Adam Kalai 외

Word embeddings, which represent a word as a point in a vector space, have become ubiquitous to several NLP tasks. A recent line of work uses bilingual (two languages) corpora to learn a different vector for each sense o…
