Using InfraNodus you can specify a category / tag for every statement that you add into the graph. Like this you can then filter the statements and the graph data based on the tags and categories that you choose.
Quick Video Tutorial:
Option #1: Manually Adding Data with Categories
In order to do that you can use the single or double [squarebrackets], so the statements like this:
apples and oranges are delicious [fruits]
cucumbers and tomatoes go well together [vegetables]
will be categorized under "fruits" and "vegetables" accordingly.
You will then able to filter them using the Statements > Filter tab at the top:
You can also select several categories at once, if you press and hold the Shift button while selecting the category.
You can remove the selection if you click on the All the Statements link.
Every time you select a category, the graph statistics for it is recalculated (and a new graph is rendered), so you can compare the most important terms and topics in between the categories using the Analytics panel.
Option #2: Automatically Adding Categories when Importing Data (RSS)
Note, that some of the Apps inside InfraNodus will automatically create categories for your data. For example, when you are visualizing the news of the day using the RSS feed, each RSS news source (its domain) will be added as a category. So you will be able to quickly see the topics that every separate news source is using.
Option #3: Adding Categories from CSV / Excel Data Import
You can also add the categories when you are importing the CSV data.
In order to do that, choose the CSV import app and then select the CSV file you'd like to import.
You can then select the column(s) you'd like to get the data from and specify which column(s) will be used for tags.
So, for example, if you are importing a file with your Asana tasks or customer reviews and there is a column that has a tag (e.g. type of task or gender of the customer), you can specify it in the columns section of CSV import, so that this column is used for categorization of data:
Additional Settings and Controls
You can also control the behavior of this function. The default behavior is:
• the data added in [square brackets] will be kept in the statement but will not be added into the graph and will only be used for categorization.
You also have two more options:
• the data added in [square brackets] will be removed from the statement, added into the graph, and will be used for categorization (so you have the categories both as the graph nodes and filter tags)
• the data added in [square brackets] will be treated just like normal text (so not added as categories and not treated differently)
You can change that in InfraNodus Settings > Graph Editor Settings:
