ABSTRACT

This research parsed entries of eight contemporary art journals from 1960 to 2015 by Natural Language Processing (NLP) and got 7000 words. These words were then analyzed by three methods: 1) word frequency, 2) word frequency trend analysis based on linear regression, and 3) word frequency variation model analysis based on curve clustering. The data were classified into a five-category set and a ten-category set, along with a ten-word-frequency-variation-model. Based on the above data study, this paper analyzed the resulted trends from political, economical, technological and art perspectives. The conclusion is that hot topics in American contemporary art vary with contemporary social backgrounds.

1. Introduction

The term contemporary art, is widely referred in all occasions. However, it is almost impossible to give a universal definition to this term because of the close connection with history, geography, cultures, politics, technology and economics, and the huge diversity of themes, forms and media of contemporary art. Therefore, “what is contemporary art?” naturally becomes a question for every art historian and everyone visiting a modern art museum. One difficulty to define contemporary is that for a certain period in history, all the art forms created in that period can be called “contemporary,” so the definition of contemporary for art historians varies from one person to the other. Alexander Alberro ( Alberro , 2008

In the constantly evolving machine learning field, the application of deep learning methods in art domain is not unprecedented. For example, Saleh and Elgammal designed a classification algorithm that is capable of distinguishing different art genres from a range of fifteen centuries in a relative high accuracy ( Elgammal & Saleh, 2015

2. Data and Methods

2.1. Data Source

There is no clear starting point of contemporary art in art history field. However, most scholars choose 1960s as an important period for emergence of contemporary art due to the intensive social-political revolutions (e.g. human rights, feminism and gay right movements) and explosive development of science and technology. The rapidly changing nature of this specific period stimulates the artists’ ideologies and their opinions on contemporary art.

Therefore, this research chose the year 1960 as its starting point, including articles of eight influential art history journals from 1960 to 2015 in every fifth year as our sample data. The journals are Afterall, Art Hournal, Frieze, Grey Room, Leonardo, October, the Art Bulletin and The Journal of Aesthetics and Art Criticism. All of them are leading journals covering an international range of art themes and focus on discussion of art from 20th and 21st centuries. Among these journals, Art Journal, The Art Bulletin and The Journal of Aesthetics and Art Criticism have the broadest coverage of the time period. The number of articles from these three journals included at each time point is summarized in Table 1.

Table 1. Summary of amounts of articles from the three journals in each time point.

2.2. Word Frequency Analysis

All articles were saved in TXT format, with articles from the same year under the same directory. There are twelve directories in total with names 1960, 1965, 1070, 1975, 1980, 1985, 1990, 1995, 2000, 2005, 2010 and 2015 respectively. For each directory, a word count was performed on all articles under it. We used Natural Language Toolkit (NLTK) to parse texts and remove stopwords (NLTK 3.3 Documentation, 2018). NLTK is the most used Python library in natural language processing. We only kept words with frequencies larger than zero in all twelve time points and there are more than 8000 of them. After filtered out all punctuation symbols and numbers, about 7000 words were left. Ten of them were chosen randomly as examples in Table 2.

2.3. Word Frequency Trend Analysis

From Table 2, we can see each row can form a time series. We processed each row by linear regression. The resulted slope of the curve shows the trend of frequency variation of a word. To distinguish these trends, we categorized the slopes for all words into five categories (Table 3). Table 3 shows the values of all slopes, i.e. the absolute trends, are very small generally. Then, we calculated the slope-to-mean ratios as the relative trend. Again, we categorized the relative trends into ten categories (Table 4).

2.4. Word Frequency Curve Cluster Analysis

Different from Section 2.3, in which trend cluster analysis was introduced, non-trend cluster analysis is discussed in this section.

Table 3. Absolute trend of word frequency.

Table 4. Relative trend of word frequency.

A fifth-degree polynomial was generated to fit the data of each word at the twelve time points. Ignoring the offset terms, we performed cluster analysis on the five polynomial coefficients. The coefficients were categorized into 10 groups. For each group, the number of words it contains was summarized in Table 5, and its average variation trend was plotted in Figure 1.

3. Results and Analysis

Multiple types of information were obtained by word frequency trend analysis. Sixty words with the most rapidly increasing frequencies were listed in Table 6. More tables and graphs were put in Github due space limitation, including the lists of two hundred words with the most rapidly increasing/decreasing frequencies. Part of the codes were also published in Github: https://github.com/gaojunhui68/Word-frequency-analysis-python.

Since it is impossible to answer “what is contemporary art?” by a simple due to its dynamism, we instead tried to describe what has happened in contemporary art field from several aspects which are intimately associated with contemporary art: politics, economics, technology and, in the end, art concept itself. In order to do this, we use the results from our word frequency data to guide our analysis.

3.1. Trend under Political Environment

The result generated by word frequency analysis will be discussed here. As Figure 2

shows, from 1960 to 2015, the frequencies of four terms, politics, democratic, gay and protest all shows an increasing. From Table 7, politics is the term with most obvious increasing slope. Its explosively rising frequency at the year 1995 is paralleled with the turbulent political environment at that time, such as World Trade Center Bombing in 1993, Nelson Mandela elected as the president of South Africa in 1994 and Oklahoma City Bombing in 1995.

Responds to contemporary politics is one of the major themes of contemporary art. In the 20th century, especially the series of worldwide civil rights movement starting at the sixties provided the art field with abundant topics. For example, political events like the Cuban Revolution in 1950s, Vietnam War, African-American civil right movements all appears frequently in various artists’ works.

3.2. Trend under Technological Environment

Table 5 contains ten categories of words classified by curve cluster analysis in section 2.4. In category 9, the similar frequency variation patterns of science and technology indicates that the influence of technological development on contemporary increased sharply from the year 1970. Some of the influential events include JVS launched videocassette recorders in 1975 and IBM launched first

personal computer in 1981. The newly invented mediums attracted a wide attention from contemporary art field. Figure 3 shows that, the word frequencies of new art mediums such as films and media began to surge from 1980. Simultaneously, these new forms of art mediums started to replace some of the traditional medium and ideologies: in Figure 4, the frequencies for words associated to relatively “classical period” like tonal, rococo, madonna, annunciation have obvious negative trends. We are going to discuss the positive and negative trends below.

One reason for the rising frequency of technology-related words is that photography and public media gained popularity during period of industrialization. Especially the invention of the camera in the 19th century, it not only brought intense discussion on the temporality of art, but also pushed artists to go beyond the traditional spatial representation on canvas, and to explore new possibilities of spatiality. At the beginning of the 20th century, the French critic Rivière criticized the that “nothing is more hypocritical than perspective” on the canvas (Rivière, 1912). In the French critic, Olivier Hourcade’s opinion, “illusion is a trick, a lie, and flatness, line and shape are the truth.” (Hourcade, 1912) The influence of camera does not stop at the surface of physical representations but extends to artists’ internal ideology. Because of the incomparable precision of the

Words with increasing frequencies: media, film, spatial, planar, subjectivity, rationally, rationality, epistemology, epistemological.

Words with decreasing frequencies: sarcophagus, basilica, pillars, Vitruvius (Rome architect), mosaic, mosaics, annunciation, triptych, madonna, ritualistic, rococo, watercolors, tones, tonal, definable.

3.3. Trend of Art Concepts

In history of art, meanings of certain concepts evolve along time, but others remain relatively constant throughout the history. We are going to discuss some examples from Table 3. The variation of word frequencies of the chosen words is displayed in Figure 5: all chosen words show constant or a rising trend during the fifty-five years, such as modernism.

・ Modernism: it has been one of the major topics of art historians since 1870s. At the beginning, modernism was defined as an opposition to traditional elitism, stating art should come from ordinary like just as the food cans in Andy Warhol’s prints. After the 19th century, modernism became the opposite to consumerism as we discussed in section 3.2. The content of modernism changes with specific historical and social contexts. Therefore, it is a good starting point to understand the nature of contemporary art.

・ Audiences, reflective: the changing relationship between artworks and audience also marks the difference between contemporary art and traditional ones. The autonomy of the narrative components in traditional form make the artwork relatively independent of audience. Whereas, audience’s interaction with the artwork is a necessary part of contemporary art. For example, the representative minimalism work Die, 1962 by Tony Smith itself is just a 6’ × 6’ × 6’ cube in the center of a room. The purpose of the work is to induce audience with a sense of surprise or disappointment of its minimalism, and hence emphasize audience’s self-consciousness that I am in this room looking at a simple cube. Without audience, this Die will lose its meaning. Most of the contemporary artworks in 20th century care about the connections among audience, artworks, and the space of exhibition.

・ Temporality: the relationship between artwork and time is also a crucial topic in art history. The invention of camera brought us the discussion of temporary and permanence. Temporality is an inseparable factor of contemporary art forms like land art, public art, architecture and sculptures etc.

・ Skepticism, challenge: Artists’ challenge to the past and present exists in all time period. From the 15th century until now, we have the Renaissance artists challenged the dark Middle Age; we saw the great works of impressionists

4. Discussion and Conclusion

We analyzed the articles from eight art history journals from 1960 to 2016 by word frequency analysis, trend analysis and cluster analysis, and found that the word frequency variation of contemporary art terms is closely related to the change of the social contexts in corresponding time period. This linkage suggests that word frequency statistics is a sensitive tool of studying the trend of contemporary art, or even the development of the contemporary society. The data of word frequency, i.e. text, are a reliable medium of history recording. Therefore, text analysis could become our magnifier to explore the development of art and society. Furthermore, compared to human researches, the relative objective machine algorithm reduces possible bias from traditional data analysis methods, and hence provides scholars with suggestions of new perspectives and directions.

This research has several limitations: 1) the studies data include only art journals in English due to authors’ limited language ability, and half of the journals are published in United States. The lack of articles from other countries like European, Asia and Africa results in bias towards the situation in the US. 2) The number of art history journals included in the data is relatively small compared to the number of current publishing art journals. Also, the time interval (five years) is also relatively long, so the result might not be able to reflect completely the trend within the five-year interval. 3) The algorithm parsed the texts in units of word. Therefore, terms exiting in form of phrases or sentences are ignored by the algorithm, such as names and titles of artworks. 4) Words with similar or the same semantic meanings but different parts of speech were not merged into one unit, which could cause the statistical frequency of certain concept to be lower than its weight in reality.

To conclude: text analysis is a reliable tool to study the trend of arts and the change in society. In future studies, we believe the combination of text analysis with other methods like visual recognition, mechanical translation can bring a broader view of data science from a global perspective.
