SWOT Analysis for
Helpful Harmful
Strengths• Makes it easy to explore network graphs.
• Providing easy access to social media network data streams, advanced network metrics, text and sentiment analysis, and powerful report generation.
• Supported by a global network of academics from a wide variety of disciplines.
• Creates insights into social media streams with just a few clicks
• Graph Metric Calculations: easily calculate basic network metrics like degree, and NodeXL Pro adds calculation of betweenness centrality, closeness centrality, eigenvector centrality, PageRank, clustering coefficient, graph density and more.
• Flexible Import and Export: import graphs from GraphML, Pajek, UCINet, and matrix formats
• Direct Connections to Social
• Zoom and scale: zoom into areas of interest, and scale the graph's vertices to reduce clutter.
• Flexible Layout.
• Easily Adjusted Appearance
• Dynamic Filtering
• Powerful Vertex grouping: group the graph's vertices by common attributes,
• Task Automation: Perform a set of repeated tasks with a single click.
Weaknesses• Low ease of use
• Importing data from social networks not working properly
• Dependence on Windows: Not running on Excel for Mac OS
• No undo option when moving the vertices in the graph and making layout changes.
• Always tries to fit the graph in one window size. It seems that the output of the graph layout is different when using a larger screen and zooming out on a small screen.
• Not possible to align all or a set of vertices to left/right or top/botttom. making manual layout manipulation difficult.
Opportunities• Mapping, measuring and understanding the landscape of social media.
• Social network analysis (SNA) is a powerful way to organize a connected world. Network analysis can reveal insights into the way things connect with one another and form groups.
Threats• Dependence on Windows: Not running on Excel for Mac OS
• Low ease of use
• Competition
• License and intellectual property rights issues
• Data ownership
