Use Case: SEO and Market Research

Problem: How to find what people search for but do not yet find?

Identify the gap between the current informational demand and supply in order to know which keywords to target in your content and marketing strategy.

Solution: Use InfraNodus to build a graph that shows the difference between the demand and supply.

InfraNodus will import search results for your query, build a graph for it, and overlay it with the related search phrases graph. This way you can see the current picture of informational demand and supply, as well as the main topical clusters within.

You can use this insight to know what keywords to target when creating the content and marketing strategy. You can also look at what's present in the current demand (search queries used) vs. current supply (search results people get) to address those gaps.

Use Case: Creative Writing and Thinking

Problem: How to write about a certain topic and generate new ideas?

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. It will then use the AI to help you generate research questions that bridge those gaps.

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.

How Text Network Analysis Works

Network analysis and graph visualization help you cope with the informational overload and make sense of data.

Here is how it works:


1. Add Any Text or Data

You can use this approach for your research, creative writing, marketing feedback study, SEO purposes, news analysis, etc.

Add any text (speech-to-text available), notes, or import your Gephi graph, Evernote data, Twitter feed, or Google search results snippets.

The text is converted into a graph where the words are the nodes and the co-occurrences are the connections between them, so you can see all your disjointed bits and pieces of data at once, as a big picture.

Create a Text Network Graph

2. Get a Visual Overview

The network will then be generated from the text or data you added. The most influential words in the graph (nodes with the highest betweenness centrality) are shown bigger, while the words (nodes) that occur more often together are aligned into topical clusters and have distinct colors.

The graph will show you not only the main topics and the most influential terms, but also the relations between them, making it a much better visual summary tool than the traditional tagclouds.

Overview Data with Text Network Visualization

3. Generate Insight

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.

You can also export your data as a CSV file (with the InfraNodus insights) for further analysis or to use as a training data for your neural network applications.

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. Focused and, yet, adaptive. 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 analyzes 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.

We also provide an API to ensure that this way of thinking is available not only to humans, but also to other machines, applications, AI programs, and machine learning algorithms.

Cognitive Variability: Panarchic Thinking with InfraNodus

Panarchic thinking

InfraNodus is especially designed to promote cognitive variability. Too often people get stuck with a certain idea or a pattern of thinking. InfraNodus can be used as a mind antivirus against obsessive loops — biased ideas, mundane patterns, totalitarian thinking, propaganda, and narrow-mindedness — proposing a kind of thinking that is pan~archic: spanning a range of states and modalities.

Using text network analysis, InfraNodus identifies the structure of the discourse through the measures of network modularity, distribution of influence, and narrative variability. It then uses its algorithms and AI to steer this structure towards a more adaptive and open state.

If the discourse is too biased towards a certain idea, InfraNodus will steer it towards diversification. If the discourse is too dispersed, InfraNodus will steer it towards more focus.

In plain terms, if InfraNodus was a conversational partner (which you can experience with the AI Chat App), it would support a conversation for some time, but then also switch the subject and go on a tangent towards a different topic. After some time, it will bring the conversation back to the central ideas, stay there for a while exploring the nuance, and then shift the subject to a new topic again.

Cognitive polysingularity: network variability dynamics.

In the technical terms, it works the following way:

1→2 #bias #growth #vector #exponent:
If the discourse is too biased towards a certain group of concepts (stage 1 to 2 on the graph), InfraNodus will highlight the less represented ideas and propose you to explore them and to connect them (50%/50% explore / focus ratio and 50%/50% zoom in / out ratio at the stage 2).

2→3 #focus #saturation #plateau:
This will bring the discourse towards a focused state (stage 2 to 3). Higher connectedness, focus on multiplicities, increasing the scale, zooming out, linking ideas more than exploring (80% to 20%).

3→4 #focus #conservation #intensification:
Now we can start zooming in again, decreasing the scale, connecting ideas within a smaller area, deepening the focus inside the existing structure (stage 3 to 4 on the graph).

4→5 #diversification #assimilation #release:
Once the discourse has become even more "focused" (stage 4 to 5), InfraNodus will also suggest to develop the specificities, zoom in further, go bigger scale, and, thus, reduce (global) focus and increase the proportion of exploration again (to 20%).

5→6 #diversification #redirection #fractalization:
It will then propose to diversify the discourse by zooming out and exploring more clusters, developing each of them further (stage 5-6: moving between locally related ideas and also jumping across the structural gaps in the graph).

6→7 #dispersion #reogranization:
At some point, we shift towards dispersion by giving more weight to the exploration process, rather than focus (state 6-7: dispersion).

7→8 #dispersion #reset:
Once the scale is large enough, we zoom into the small scale again while exploring until we find a new concept we'd like to develop (stage 7-8).

8→1 #bias #genesis:
We then focus on it and develop it further again (stages 8 to 1).




InfraNodus is used by researchers, writers, marketing professionals, corporations, and NGOs — Greenpeace, Procter & Gamble, and others. Here's what some of our supporters have to say:

Technical Support

Check out our support pages, so you can see how to create the new network graphs, how to read and interpret them, how to discover the hidden patterns in your data and share the results of your research.

1. How to Create a New Graph

The most basic way to create a new graph is to use the hashtags. Each hashtag is a node, their co-occurrence is the connection between them. You can also use normal text to build your text graphs automatically. More on Creating the Graphs

2. How to Read and Interpret Network Visualization

Studies have shown that diagrams and especially network representation of data makes you think more of connections in your data. You can identify the main elements as well as the relations between them and — most importantly — discover the gaps in your knowledge using the graphs. More on Reading the Graphs

3. Find the Right Excerpt in Text

Network graphs are great for non-linear reading. Look at the graph, find the part you like, click on the nodes, and you'll see the excerpt of your original data that contains this exact combination. More on Nonlinear Reading

4. How to Import Text and PDF files

You can import and visualize your text files or PDF documents. In order to do that, just upload the file and InfraNodus will do the rest. More on Visualizing PDFs
