• Abstract: Powerful sentence encoders trained for multiple languages are on the rise. These systems are capable of embedding a wide range of linguistic properties into vector representations. While explicit probing tasks can be used to verify the presence of specific linguistic properties, it is unclear whether the vector representations can be manipulated to indirectly steer such properties. We investigate the use of a geometric mapping in embedding space to transform linguistic properties, without any tuning of the pre-trained sentence encoder or decoder. We validate our approach on three linguistic properties using a pre-trained multilingual autoencoder and analyze the results in both monolingual and cross-lingual settings.

  We find that the existence of code-switching, alternating between different languages within a context, is key to multilingual capabilities. To better explore the power of code-switching for language alignment during pre-training, we investigate the strategy of synthetic code-switching.

• Improving Multilingual Neural Machine Translation by Utilizing Semantic and Linguistic Features [18.76505158652759]
  We propose to exploit both semantic and linguistic features between multiple languages to enhance multilingual translation. On the encoder side, we introduce a disentangling learning task that aligns encoder representations by disentangling semantic and linguistic features. On the decoder side, we leverage a linguistic encoder to integrate low-level linguistic features to assist in the target language generation.

  In a multilingual neural machine translation model, an artificial language token is usually used to guide translation into the desired target language. Recent studies show that prepending language tokens sometimes fails to navigate the multilingual neural machine translation models into right translation directions. We propose two methods, language embedding embodiment and language-aware multi-head attention, to learn informative language representations to channel translation into right directions.

  We study cross-lingual semantic parsing as a zero-shot problem without parallel data for 7 test languages. We propose a multi-task encoder-decoder model to transfer parsing knowledge to additional languages using only English-Logical form paired data. Our system frames zero-shot parsing as a latent-space alignment problem and finds that pre-trained models can be improved to generate logical forms with minimal cross-lingual transfer penalty.

• Revisiting Language Encoding in Learning Multilingual Representations [70.01772581545103]
  We propose a new approach called Cross-lingual Language Projection (XLP) to replace language embedding. XLP projects the word embeddings into language-specific semantic space, and then the projected embeddings will be fed into the Transformer model. Experiments show that XLP can freely and significantly boost the model performance on extensive multilingual benchmark datasets.

  We use singular vector canonical correlation analysis to study what kind of information is induced from each source. We observe that our representations embed typology and strengthen correlations with language relationships. We then take advantage of our multi-view language vector space for multilingual machine translation, where we achieve competitive overall translation accuracy.
