Converting text into a graph of concepts involves using natural language processing (NLP) and graph theory to represent the relationships between words and concepts in a text. Here’s a comprehensive guide on how to achieve this:

1. Text Preprocessing:

• Tokenization: Break the text into individual words or phrases, known as tokens.
• Lowercasing: Convert all text to lowercase to ensure consistency.
• Stopword Removal: Eliminate common words (e.g., “the,” “and”) that don’t carry significant meaning.
• Stemming/Lemmatization: Reduce words to their root form to consolidate related terms.

2. Entity Recognition:

• Use Named Entity Recognition (NER) to identify entities such as people, organizations, locations, dates, and more. This step helps in understanding the key entities in the text.

3. Dependency Parsing:

• Analyze the grammatical structure of the sentences to identify relationships between words. Dependency parsing helps in understanding how words are connected in a sentence.

4. Concept Extraction:

• Apply techniques to…
