Edit GraphOfdocs/config_experiments.py to setup the experiments and run experiments.py.
Prequisites:
Windows 1064-bit / Debian basedLinux64-bit.Python 3(min. version 3.6),pip3(&pylauncher Windows-only).- Working
Neo4jDatabase (min. version 3.5.12).
Download the project from the green button above, unzip it,
and then open a cmd terminal to this folder and type pip3 install -r requirements.txt.
This command will install the neccessary Python libraries* to run the project.
We ran the following commands to update Python, git,
clone the project to a local folder and install the necessary Python libraries*.
sudo apt install python3.6
sudo apt install git-all
git clone https://github.com/NC0DER/GraphOfDocs
cd GraphOfDocs
pip3 install -r requirements.txt* Optionally you could create a virtual environment first,
* to isolate the libraries from your python user install.
* However the setup script doesn't downgrade existing libraries,
* so there's zero risk in affecting your local user install.
Create a new database from the Neo4j desktop app using 3.5.12 as the min. version.
Update your memory settings to match the following values,
and install the following extra plugins as depicted in the image.
Hint: if you use a dedicated server that only runs Neo4j, you could increase these values,
accordingly as specified in the comments of these parameters.
Run the GraphOfDocs.py script which will create thousands of nodes,
and millions of relationships in the database.
Once it's done, the database is initialized and ready for use.
You could use the Neo4j Browser to run your queries,
or for large queries you could use the custom visualization tool
visualize.html which is located in the GraphOfDocs Subdirectory.

abstract="This paper introduces a novel approach to represent multiple documents as a single graph, namely, the graph-of-docs model, together with an associated novel algorithm for text categorization. The proposed approach enables the investigation of the importance of a term into a whole corpus of documents and supports the inclusion of relationship edges between documents, thus enabling the calculation of important metrics as far as documents are concerned. Compared to well-tried existing solutions, our initial experimentations demonstrate a significant improvement of the accuracy of the text categorization process. For the experimentations reported in this paper, we used a well-known dataset containing about 19,000 documents organized in various subjects.",

abstract="This paper introduces a novel graph-based approach to select features from multiple textual documents. The proposed solution enables the investigation of the importance of a term into a whole corpus of documents by utilizing contemporary graph theory methods, such as community detection algorithms and node centrality measures. Compared to well-tried existing solutions, evaluation results show that the proposed approach increases the accuracy of most text classifiers employed and decreases the number of features required to achieve `state-of-the-art' accuracy. Well-known datasets used for the experimentations reported in this paper include 20Newsgroups, LingSpam, Amazon Reviews and Reuters.",
