In Reading for the Plot , Brooks explores how stories—inventing them, writing them, reading them—illicit and address our desires. In doing so, he suggests why stories matter. Despite the difficulty I had arriving at this list of five, once I had it and had settled on it, I felt and continue to feel good about it. I do have one reservation however: I think it is lessened by having no work of general history. The case of the Norm character is more diffuse. The analysis of the dialog alone cannot reveal the functions of this character in the film.
In this function, he is given a considerable part of the expository text to speak, and, through knowledgeable questions, elicits more backstory especially from Grace. The integration of these functions, namely rival, tutor, backstory narrator, and contrast character, into one character is specific to this film, so that it is harder to talk about a generalizable character type here. These functions can be distributed or grouped differently in other films.
It has to be noted that these particularities only emerge within one screenplay, i. This observation means that it is hard to detect a character type across a number of screenplays on the basis of the absolute presence of the features. What can be compared across films are only relative frequencies of certain forms and behaviors. The exercise also shows that what is revealed with these annotations is primarily the function of a character in the film together with the power status with regard to the plot and to other characters.
The fictional personality, i. Their combination with lexico-semantic analyses would reveal more about aspects of characterization, and could answer the question whether function and character are correlated: the usual list of character types e. This point is illustrated by the characters chosen for profiling: they would both be classified as supporting characters to the hero, so that the distinctions in verbal behavior are neutralized when the group is considered as a whole.
For a partitionment that reflected more or less the timing of the film, we chose the original screenplay as a basis. The partitions were based on the number of lines in the screenplay, with minor adjustments to respect scene boundaries. The section boundaries were then transferred to the extracted dialog, so that the number of dialog lines per section varies considerably, depending on the proportion of descriptive text per sequence. Based on the manually adjusted scene boundaries, histograms that reflect the interaction frequencies of characters in the screenplay were extracted automatically.

These simplified representations were used to automatically identify major incidents in the plot plot points using the Sobolev norm Wilson, Baddeley, and Owens The Sobolev norm was first introduced to compare gray-scale images and is a natural choice for histogram comparisons. The results are illustrated in Figure 5 , and the heatmaps used in this task are shown in Figure 6.

The degree of dependence is stated numerically and reflected in the gray levels of cells. Blank cells indicate that the feature has not been selected. Structural differences in the plot Avatar based on differences obtained from histogram representations of manually adjusted scene boundaries. The computed differences represent the change of character interaction compared to the previous scene. Automatically extracted plot points peaks in the interaction profile are shown as red dots. The plot points assumed on the basis of the common three-act structure are indicated by orange bars. Histogram representations of manually adjusted scenes of the screenplay of Avatar.
For better visual inspection, frequencies are colored in log space. The close fit of the histogram representation to the assumed three-act structure shows that it is possible to computationally detect the form of a screenplay.
The heatmap shows in more detail the nature of the changes that occur in the interaction patterns especially at the turning points of the plot. The varying patterns of the sequences in the second act are reflections of the dramatic complication. The transition to the third act is dramatically visible in sequence The protagonist is now clearly the central figure on his side, all interaction is with him. Although Jake utters more orders in absolute numbers 59 vs. The commands of both become more frequent toward the end of the film.
The hero becomes not only the pivot of interaction, but also the leading character. The rate of commands uttered by Quaritch also rises in this phase, culminating in the final battle sequence 11 , when as many as of his utterances have command character. This behavior is significant for the plot insofar as the refusal by some subordinates to obey his orders becomes the telltale sign of his ultimate defeat. There is a difference in the style of commands between the two roughly as between a team leader and an army officer , which have to be revealed through other features of their utterances. Changes of verbal behavior over time can therefore provide insights into the development of characters in a film, and the major plot points are the moments where such changes should be looked for, in particular for the main characters who drive the plot.
Percentage of commands and command-like utterances by protagonist Jake and antagonist Quaritch in Avatar over time. In this paper, we have described an integrated approach for the identification of dramatic character types based on sequences of dialogs extracted from action movie scripts.

Specifically, we applied an unsupervised representation of text, supervised quantization of vectors, and analysis of semantic dialog graphs incorporating social relationship and expressivity of characters. The approach was evaluated on a new data set of action movie characters.

The presented approach demonstrates an improvement over baseline methods, and also enables for a more in-depth analysis of features that convey characteristics of latent personae in sequences of dialogs. In-depth analysis of a single screenplay has provided insights into character profile and development that will be used in further research.

Introduction The research outlined in this paper aims at the modeling of conversational characters in virtual agents and social robots. The role of dialog in film The first question for our line of research is whether film dialog our primary source actually provides enough clues to infer and distinguish characters from it. Without ignoring the role of image and sound, she puts film dialog back in its place as an important element in film, and distinguishes six primary functions, presented below: Anchorage Icons and symbolic images are used to signal time and place of a movie, but additional dialog is often necessary to create the story world diegesis for the audience, as images are basically polysemous.
Narrative causality Dialog also plays a crucial role in establishing the logic of the film sequences and of the depicted events. Verbal events The number of instances where an event in a film is actually verbal should not be underestimated. Character revelation A character is a construct from the very many different signs deployed in a film, among them the behavior in dialogs.
Code of realism A proportion of dialog in every film serves primarily as a representation of ordinary conversational activities, e. Kozloff adds to these aesthetic, persuasive, commercial, and ideological functions such as: exploitation of the resources of language e. Screenplay as text genre What is more, film dialogs for text-based studies as the present one are mostly extracted from screenplays some authors make and use transcripts from the screened film, but the effort required limits the amount of data that can be collected with this method.

Methods Linguistic markers In order to allow for semantic reasoning at the sentence level, we explored use of the skip-thought model Kiros et al. Table 3. Semantic dialog graph features Investigations of communication characteristics and social roles of actors in social networks through descriptive analysis have gained increasing consideration Myers et al. In particular, we characterize a character in terms of the following measures computed on each graph: Closeness centrality : How easy can reach out to other characters.
Descriptive analysis of semantic dialog graphs The measures used in this work are formally defined as follows. Examples of semantic dialog graphs We analyzed to which extent different characters are captured using closeness centrality, betweenness centrality , and clustering coefficient in semantic dialog graphs. Figure 1. Figure 2. Figure 3. Evaluation of an integrative approach We conducted experiments to compare the different representations and measured their capacities to identify character types from sequences of multiparty dialogs and character interactions.
