Book Recommender System
Data Science Seminar Project
Winter Semester 2021/22

Recommending books using a Recommender System based on goodreads.com data from the UCSD Book Graph[^fn1]
Steps needed:
- Data Preparation: Downloading Data, reading into Pandas DataFrames
- Data Cleaning and Preprocessing: Keeping only needed data, string cleanup, etc.
- Data Model Creation: creating Word Embeddings from item data like title, description, authors, etc.
- Recommender System Model Creation: selecting a Neural-Network-based recommender system, e.g. NCF, WDN, DCN, etc.
- RS Training
- RS Evaluation
Optional:
- combining the Book data with another dataset from a different domain, e.g. MovieLens 25M[^fn2] to create a multi-media recommender system, suggesting books based on movie preferences and vice versa.
- this would need more text processing to find similarities between the datasets, e.g. by extracting tags from movies and matching them to book descriptions and goodreads shelf-names
=> this idea has since been scrapped, since it's out of reach in the scale of this student project.
this repo needs some cleanup, main file is the keras_dcn.ipynb Notebook
