.. index:: single: MyMediaLite
The Book Recommendation Application uses an open-source recommendation engine named MyMediaLite. This section provides more detail on how integration with the recommendation engine occurs.
The general steps are:
- Download MyMediaLite and install in the /opt/book directory
- MyMediaLite uses the .NET framework. If you are running on a non-Windows operating system you can use the Mono framework to emulate .NET. The command to install Mono on Ubuntu Linux is: sudo apt-get install mono-complete
.. index:: single: rating.txt single: item_attributes.txt single: item_predict.txt
In order to generate book recommendations, MyMediaLite uses several different files as shown below.
| File Name | Direction | Description |
|---|---|---|
| rating.txt | Input | Contains a record for each book and a computed rating based on total downloads |
| rating_test.txt | Input | Contains a record for each user, the book id, and their rating for the book. |
| item_attributes.txt | Input | Contains a record for each book and a unique attribute id for the language and subject |
| item_predict.txt | Output | Contains a record for each user and recommended books |
Each of these files is generated by the Book Utility Java code discussed in the previous section.
Note
MyMediaLite can use a variety of statistical methods for making recommendations. More information can be found on the project's homepage.
