+# British Library Books genre detection demo
+This demo allows you to play with a 'genre' detection model which has been trained to predict, from the title of a book, whether it is 'fiction' or 'non-fiction'.
+The model was trained with the [fastai](https://docs.fast.ai/) library on training data drawn from [digitised books](https://www.bl.uk/collection-guides/digitised-printed-books) at the British Library. These Books are mainly from the 19th Century. 
+The demo also shows you which parts of the input the model is using most to make its prediction. You can hover over the words to see the attention score assigned to that word. This gives you some sense of which words are important to the model in making a prediction.
+The examples include titles from the BL books collection. You may notice that the model makes mistakes on short titles in particular, this can partly be explained by the title format in the original data. For example the novel *'Vanity Fair'* by William Makepeace Thackeray
+is found in the training data as:
+
+```
+Vanity Fair. A novel without a hero ... With all the original illustrations by the author, etc
+```
+
+You can see that the model gets a bit of help with the genre here 😉. Since the model was trained for a very particular dataset and task it might not work well on titles that don't match this original corpus. 
+
+## Background 
+This model was developed as part of work by the [Living with Machines](https://livingwithmachines.ac.uk/). The process of training the model and working with the data is documented in a [tutorial](github.com/living-with-machines/genre-classification). 
+
+## Model description
+This model is intended to predict, from the title of a book, whether it is 'fiction' or 'non-fiction'. This model was trained on data created from the [Digitised printed books (18th-19th Century)](https://www.bl.uk/collection-guides/digitised-printed-books) book collection. 
+This dataset is dominated by English language books though it includes books in several other languages in much smaller numbers. This model was originally developed for use as part of the Living with Machines project to be able to 'segment' this large dataset of books into different categories based on a 'crude' classification of genre i.e. whether the title was `fiction` or `non-fiction`.
+You can find more information about the model [here]((https://doi.org/10.5281/zenodo.5245175))
+
+## Training data
+The model is trained on a particular collection of books digitised by the British Library. As a result, the model may do less well on titles that look different to this data. In particular, the training data, was mostly English, and mostly from the 19th Century. The model is likely to do less well with non-English languages and book titles which fall outside of the 19th Century. Since the data was derived from books catalogued by the British Library it is also possible the model will perform less well for books held by other institutions if, for example, they catalogue book titles in different ways, or have different biases in the types of books they hold. Some of the data was generated using weak supervision. You can learn more about how this was done [here](https://living-with-machines.github.io/genre-classification/04_snorkel.html)
