     <li><a href="https://hf.co/sentence-transformers/distiluse-base-multilingual-cased-v1">Sentence Encoder Ranker</a>: To rerank the candidate contexts retrieved by DPR for the generative model to see. This also selects the top 5 passages for the model to read, it is the final filter before the generative model. For this we used 3 different configurations to human-check (that's us seriously playing with our toy) the answer results, as generated answers depended much on this piece of the puzzle. The first option, before we trained our own crossencoder, was to use a <a href="https://huggingface.co/sentence-transformers/distiluse-base-multilingual-cased-v1">multilingual sentence transformer</a>, trained on multilingual MS Marco. This worked more or less fine, although it was noticeable it wasn't specialized in Spanish. We then tried our own CrossEncoder, trained on our [translated version of MS Marco to Spanish](https://huggingface.co/datasets/IIC/msmarco_es). It worked better than the sentence transformer. Then, it occured to us by looking at their ranks distributions for the same passages, that maybe by multiplying their similarity scores element by element, we could obtain a less biased rank for the documents, therefore only those documents both rankers agree are important appear at the top. We tried this and it showed much better results, so we left both systems with the posterior multiplication of similarities.</li>
-    <li><a href="https://hf.co/IIC/mt5-base-lfqa-es">Generative Long-Form Question Answering Model</a>: For this we used either mT5 (the one attached) or <a href="https://hf.co/IIC/mbart-large-lfqa-es">mBART</a>. This generative model receives the most relevant passages and uses them to generate an answer to the question. In the attached link there are more details about how we trained it etc.</li>

     <li><a href="https://huggingface.co/facebook/tts_transformer-es-css10">Text2Speech</a>: For this we used Meta's text2speech service on Huggingface, as text2speech classes are not yet implemented on the main branch of Transformers. This piece was a must to provide a voice to voice service so that it's almost fully accessible. As future work, as soon as text2speech classes are implemented on transformers, we will train our own models to replace this piece.</li>

Vimos la necesidad de hacer este sistema lo más flexible posible, para que fuera fácil interactuar con él independientemente de las dificultades o limitaciones físicas que pudieran tener las personas. Al incluir una salida de voz, aquellos que tengan problemas de visión también podrán recibir respuestas a sus dudas. Esto reduce las desigualdades de acceso a la herramienta de las personas con alguno de esos impedimentos.

 (*) Nótese que en la demo actual del sistema el usuario necesita realizar una mínima interacción por teclado y ratón. Esto es debido a una limitación de diseño de los spaces de Huggingface. No obstante, las tecnologías desarrolladas sí permitirían su integración en un sistema de interacción pura por voz.
