InfraNodus: Data Science for Your Thought
Visualize the data from your PKM vault or Evernote notes as a network graph. You can see both the [[backlink]] connections and automatically identified semantic connections between your ideas:
InfraNodus graph visualization helps to detect the gaps in your ideas. We can then use the GPT based AI to help generate insight that will bridge those gaps.
Knowledge Graph Creation & Analysis Workflow
You can import Obsidian, RoamResearch, or LogSeq vault (MD files), import your Evernote notes, or input your text directly plain text or [[wiki-links]] using the built-in text editor and viewer.
See a graph of connections between your pages with powerful network science insights that help you identify the most important elements and the gaps in your knowledge.
Switch to the concept view to view a semantic network of your second brain. You will see the most important topics and can link them inside the app.
The graphs are interactive: you can remove the words to see what's hiding behind them. You can select them to see in which context they appear.
Use the built-in OpenAI's GPT AI to generate research questions and facts that can bridge the structural gaps in your ideas. Also an interesting way to let somebody else "play" your public graph.

Case Study
Use Case: Text Mining and Topic Modeling
Problem: What are the main topics inside a text?
The current solutions are either too simplistic or too technically challenging.
Solution: Topic modeling based on text network analysis and visualization.
InfraNodus will represent the text as a network and use powerful graph analysis algorithms to identify and visualize the main keywords, topics, and their relations.

Use Case: Discourse Structure and Bias Analysis
Problem: How to identify the level of diversity and bias in a text or a network?
Suppose that we want to study the current discourse on coronavirus. What are the main topics and how diverse is the media coverage of this subject? What is the level of urgency?
Solution: Represent the text as a network and measure the diversity and bias of the graph structure.
InfraNodus represents any text as a network, so you can get insights about the structure of the discourse.
Based on the graph's modularity and distribution of influence across the different communities, we can measure the diversity of the discourse stucture and estimate its bias.

Use Case: Creative Writing & Idea Generation
Problem: How to generate new ideas for your writing or at a brainstorming session?
Whether you are brainstorming, doing research or writing you may experience writer's block or simply get stuck for new ideas.
Solution: InfraNodus will represent your text as a network providing a visual overview and helping you find the gaps where the new ideas are hiding.
Our studies have shown that network representation of text encourages one to think in terms of connections, helping you make the new links between the different parts of your text and make your discourse more coherent.
You will also be able to see the structural gaps in your writing: that's where the new ideas our hiding.

Use Case: Sentiment Analysis of Open Survey Customers Answers
Problem: Need to know what your customers think?
Open survey answers are hard to analyze. Positive / negative is not enough and tag clouds lose out the context.
Solution: Find the patterns in their open survey answers using network graphs.
With InfraNodus your customers' feedback will be visualized as a word graph where the words used in the same answer are connected.
This representation will reveal the patterns and context in your customers' answers, so you will see the main topics that appear in their feedback as well as the hidden relations between them that can't be uncovered by other tools.

Knowledge Graph Examples: Play a Second Brain
InfraNodus will also visualize a semantic network on top of your pages graph. You can switch this off, of course.
We took some existing publicly shared Obsidian / RoamResearch / LogSeq graphs and visualized them with InfraNodus.
We recommend to use the built-in GPT4 Insight AI to generate research questions or facts based on these graphs. It's very exciting, like playing with someone's brain while they are not there.

How To Enhance Knowledge Graphs Using Text Networks
Most PKMs provide rudimentary graph visualization.
InfraNodus provides an interactive graph that can be used both to explore, to navigate, and to rewire your knowledge. Here's how it works:
1. Create or Import Your Knowledge Graph
You can create your knowledge graph from your writing, using InfraNodus as your PKM. It is also possible to import any data: from AI-generated text to your own PDF documents to Obsidian, RoamResearch, LogSeq or any other system's vaults (markdown files).
The text is converted into two networks that are shown at the same time: your backlinks and semantic relations in your text.
The algorithm representes every word as a node and every co-occurrence as a connection. If a concept is mentioned in a page, it is connected to that page on the graph. If the pages are mentioned in the same statement, they are also connected.
2. Apply Network Science and Text Mining Insights
The network will then be generated from the text or data you added. The most influential nodes (concepts and pages) in the graph have the highest betweenness centrality and are shown bigger on the graph. The nodes (concepts and pages) that occur more often in the same context are aligned into topical clusters and have distinct colors.
Force-atlas algorithm is applied to create a special representation of those topical groups and influential hubs. Graph analytics is provided on every aspect of the graph's structure and individual nodes' properties.
3. Generate Insight and New Ideas
InfraNodus will identify the structural gaps in the network: parts of the graph that could be connected but are not.
It will propose you the different ways how you can bridge these gaps to produce insight and generate new ideas. For example, by using the built-in GPT AI to come up with research questions and facts. Or using your own imagination based on the text ideogram presented to you.
You can also export your data as an MD file (augmented with InfraNodus insights) and import them back into your favorite PKM tools. Or use the built-in editor to build your ideas on top of the graph.

About InfraNodus: Our Philosophy
Gregory Bateson coined a beautiful term: "ecology of the mind". What is a mind that is ecological? It has the ability to have an overview, but it can also zoom into any idea. It embraces diversity, but it can also obsess over one thing when needed. It can discover the obvious, but it can also reveal the things that are hidden and ponder the gaps that have not yet been bridged. Rational and poetic.
InfraNodus is a tool that is developed to help you think this way. It is made to promote ecological dynamics and diversity on the cognitive level. InfraNodus visualizes and analyses ideas as a network, revealing the relations and patterns within them, so you can understand the dynamic complexity of how knowledge evolves and explore the nuances of meaning.
We believe that it is especially important today to make this kind of instrument available to everybody. That's why we develop InfraNodus so that it can be accessible to everyone, solely thanks to our users' monthly contributions and based on their feedback. This is not a start-up, in fact, it is more like the project of our lives. We don't have investors or an exit strategy. We are here to stay and to evolve.
We are constantly improving InfraNodus based on our users' feedback. We are also currently developing an API to make this way of thinking available to other applications and to enable the use of InfraNodus insights for machine learning and AI applications.
If you like our cause, please, sign up for an account and give it a try, support us on Patreon, or simply let us know that it resonates, because this is the best way to motivate each other.
