まとめ
会話における単語頻度はターンの完了を予測するのに役立つ。質問の終わりにおける低い単語頻度は、物語とは異なり、話者の交代を示す。
科学分野:
- 心理言語学
- 計算言語学
- 社会言語学
背景:
- 会話の話し手は、メンタルレキシコンの単語頻度情報を使用する。
- 単語頻度は、対話におけるターン完了キューとして機能する可能性がある。
研究 の 目的:
- 会話におけるターンテイキングにおける単語頻度の役割を調査する。
- 単語頻度パターンがターンの遷移または継続を予測するかどうかを判断する。
主な方法:
- フライブルク多峰性相互作用コーパス(FreMIC)の分析。
- 質問および物語のターン構築単位(TCU)における単語頻度および関連指標の比較。
- S字型の頻度パターンを分析し、ターン遷移(TT)を予測するための混合効果モデルの適用。
主要な成果:
- TCUにおける単語頻度はS字型のパターンを示し、先行研究と一致する。
- 質問TCUの終わりにおけるより顕著な単語頻度の低下は、ターンの遷移を予測する。
- 物語TCUは、ターン継続を予測する、それほど顕著ではない頻度低下を示す。
- ターン最終の質問TCUは、名詞の右傾斜分布を示す。
結論:
- 単語頻度パターンは、リスナーが会話におけるターンの完了または継続を予期するための重要なキューとして機能する。
- この研究は、ターン遷移のダイナミクスを社会的行為と結びつけ、特に質問と物語を区別する。

Determination of Expected Frequency
2.5K
Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...

What is a Frequency Distribution
26.0K
A frequency is the number of times a value of the data occurs. The sum of all the frequency values represents the total number of students included in the sample. It is commonly used to group data of quantitative types. Frequency distributions can be displayed in a table, histogram, line graph, dot plot, or pie chart, just to name a few. A histogram is a graphical representation of tabulated frequencies, shown as adjacent rectangles, erected over discrete intervals (bins), with an area equal to...

Percentage Frequency Distribution
62.5K
A percentage frequency distribution, in general, is a display of data that indicates the percentage of observations for each data point or grouping of data points. It is a commonly used method for expressing the relative frequency of survey responses and other data. The percentage frequency distributions are often displayed as bar graphs, pie charts, or tables.
The process of making a percentage frequency distribution involves the following few steps: note the total number of observations;...

Relative Frequency Histogram
6.3K
The relative frequency depicts the proportion of data points that have each value. The frequency tells the number of data points that have each value. Like the histogram, a relative frequency histogram also has the same shape with a horizontal scale (the x-axis), but the vertical scale (the y-axis) is marked with relative frequencies (percentages of the whole) instead of actual frequencies. A relative frequency histogram is a graphical representation of a frequency distribution where the...

Expected Frequencies in Goodness-of-Fit Tests
7.0K
A goodness-of-fit test is conducted to determine whether the observed frequency values are statistically similar to the frequencies expected for the dataset. Suppose the expected frequencies for a dataset are equal such as when predicting the frequency of any number appearing when casting a die. In that case, the expected frequency is the ratio of the total number of observations (n) to the number of categories (k).

Construction of Frequency Distribution
11.9K
A frequency distribution table can be constructed using the steps given below.
First, make a table with two columns—one with the title of the data that needs to be organized, and the other column for frequency. [Draw a third column for tally marks if needed]. Then, take a look at the items given in the data set and decide if an ungrouped frequency distribution table or a grouped frequency distribution table would be more suitable. If there are large sets of different values, then it is...
