predictMEE - Predicting Missing Metadata with Entity Extraction

Requirements

Conda or miniconda installation

The predictMEE model and analysis workflow requires a variety of packages to be installed prior to running the code. The easiest way to install all the necessary packages is by installing the Anaconda3 or minconda3 python package manager.

Data

The data download script to automate the download and preprocessing of the SRA attribute-value pairs is still a work in progress. For now you can find the data that was used here.

Word Embedding Model

The downloadable word2vec model can be found here

Installation

Substituting your GH username below, you can clone this repo to the curent directory with

git clone https://username@github.com/aklie/predictMEE.git

Configuring environment

Then, install the required packages with the following commands

cd predictMEE/config
conda env create -f deep_nlp_cpu.yml  # Load the envrionment
conda activate deep_nlp_cpu  # Activate the environment

If you are planning on recapitulatiing the full analysis, you will need to mimic the file structure shown below.
