## Papers

The most cited first (OpenAlex and our library).

1. **[Extracting Semantic Orientations of Words using Spin Model](https://md.research.elamur.ai/free/en/papers/takamura-2005-extracting-semantic-orientations-words-spin/)** *(2005 · 471 citations)* The paper tackles automatic construction of a polarity lexicon, which labels English words as desirable (positive) or undesirable (negative), starting from only a handful of labelled seed words.
2. **[Controlling Output Length in Neural Encoder-Decoders](https://md.research.elamur.ai/free/en/papers/kikuchi-2016-controlling-output-length-neural-encoder/)** *(2016 · 323 citations)* The paper addresses a gap in neural encoder-decoder summarization: standard models cannot be told how long their output should be.
