Задача: предсказать рейтинг отеля на основе отзыва на Trip Advisor Hotel Reviews



Данные.


В качестве источника данных используется датасет с оценками 20 тысяч отелей, взятый с сайтa Tripadvisor. Для ограничения выборки применен коэф. 0.3. Данные сократились до 6147 наблюдений.

# Загружаем данные
hotels <- read_csv("tripadvisor_hotel_reviews.csv")
set.seed(1)
hotels <- sample_frac(hotels, 0.3)


Данные представляют собой две колонки с отзывом и рейтингом по каждому из отелей. Приводим к нижнему регистру и выводим первые значения.

Проводим разведывательный анализ данных.


Для этого сначала чистим данные. Смотрим на распределение рейтингов. Считаем количество знаков в отзывах. Проверяем зависимость рейтинга от длины отзыва.

hotels <- hotels |> 
  mutate(review = str_replace_all(review, "\\b\\d+(\\.\\d+)?\\b", "$"))
  
hotels |> 
  ggplot(aes(x = rating)) +
  geom_bar(fill = "steelblue") +
  labs(title = "Распределение рейтингов", x = "Рейтинг", y = "Количество")

hotels$lengths <- nchar(hotels$review) # подсчет знаков в отзыве
mean_lengths_rev <- mean(hotels$lengths) # среднее

# Зависимость оценки от длины отзыва
length_r <- lm(rating ~ lengths, data = hotels)
summary(length_r)

Call:
lm(formula = rating ~ lengths, data = hotels)
