Question 7 1 pts We are working with a large dataset of documents. Which of the following requires shape-coding for nodes? A word-document network, in which nodes are words and documents, and a link exists between a word and a document if it appears more than 10 times in that document A word co-occurrence network, where nodes are words, and two words are connected if they co appear in more than 10 sentences in the dataset > Question 8 1 pts A community detection algorithm gives membership scores to different communities for each node. To visualize this results, which coding can be used on nodes? O Shape Color Question 5 1 pts In a project description, we are asked to represent "high-degree nodes" in red. Which message are we necessarily communicating? Connects two or more communities Has a lot of connections to other nodes Is the most important node in the network Has more in-coming links than out-going links
