Summary
This study introduces a new method for ranking films based on citation networks, identifying foundational "milestone films." This quantitative approach offers a more diverse and objective measure of cinematic impact than traditional methods.
Area of Science:
- Network Science
- Film Studies
- Quantitative Analysis
Background:
- Traditional film success metrics (box office, reviews) are subjective and external.
- The rise of big data necessitates objective, endogenous measures of film impact.
- Existing film rankings lack diversity and rely on subjective criteria.
Purpose of the Study:
- To propose a novel, quantitative ranking method for films.
- To identify foundational "milestone films" using network analysis.
- To compare the diversity of identified films against existing subjective lists.
Main Methods:
- Constructed a multiplex network of over 40,000 international feature films based on citations.
- Applied centrality indices to analyze network structure and identify influential films.
- Developed a methodology for quantifying multidimensional cinematic references.
Main Results:
- Derived a list of "milestone films" representing the foundations of cinema.
- The identified milestone films exhibit greater diversity in genres, actors, and creators compared to existing lists.
- Demonstrated the potential of systematic quantitative investigation in film studies.
Conclusions:
- A network-based centrality approach provides a more objective and diverse measure of film impact.
- This method can uncover historically significant films overlooked by traditional rankings.
- This study bridges network analysis techniques with the quantification of artistic influence.

3.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

12.8K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

01:25Network Function of a Circuit
1.1K
Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

02:10Social Scripts
8.6K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

01:08Outliers and Influential Points
5.0K
An outlier is an observation of data that does not fit the rest of the data. It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500), while others may indicate that something unusual is happening. Outliers are present far from the least squares line in the vertical direction. They have large "errors," where the "error" or residual is the...
