# Simulated Query and Document Streams of LoTTE Forum Dataset

This dataset contains the simulated streams for the paper "*MURR: Model Updating with Regularized Replay for Searching a Document Stream*". 
Please refer to the paper for the detailed sampling process. 

The code for sampling the queries, qrels, and documents are documents in `sampling.py`. 
It is not intended to be ran but for recording purposes. 

The random numbers for sampling are also recorded in the files for futrue references. 

## Dataset Structure

```

```

`D{1,2,3}` indicates different streams and the subsequent `{0,1,2,3,4}` are the sessions ids.
