**1. Introduction**

Currently, the internet and humans cannot be separated because of the large amount of information and knowledge available on the internet with its ability to facilitate access to various things. In addition to information disclosure, the internet is also used as a place to share experiences and hobbies through social media [1].

Obtaining an overview of social media, according to Wikipedia, social media is an online platform that allows individuals to easily join, share, social networks, wikis, forums, and create blogs. Blogs, social networks, and wikis are the most common social media used by people worldwide. As of August 2017, Instagram is the sixth most popular social media platform with 700 million members.

This social media platform, commonly called IG or Insta, is an image and video sharing application that facilitates users to upload photos and videos, apply digital

filters to photos and videos, and also share them on other social media [2]. Moreover, Instagram also has several other functions, namely:


At first, social media was just a way for people to communicate with one another. As technology advances, social media allows people to express themselves as creators and thinkers, rather than just as observers. Which activities can be facilely done using Instagram. Due to the increasingly massive use of social media, marketing through social media appears to be the best option in developing their business [3].

The caption in every Instagram post is one way to attract the audience's interest to buy the goods or services being traded [4]. Audiences can interact with or respond to the post. Observations show that a post gets significantly different interactions, depending on the content of the image and the caption. When an image is uploaded with a specific caption, especially using a hashtag, the post can become a trend. The profile of a person who is a potential target market, or demographic segmentation, behavioral segmentation, and lifestyle segmentation, is related to interests. These things allow marketers to know who is paying attention and interest in the trend. According to Shopify.co.id, there are several trending Instagram categories in 2020, namely Fashion, Food & Beverage, Technology, Health & Beauty, and Lifestyle & Travel.

We can conclude that the classification of Instagram captions plays a significant role in mapping the development of trends on the platform. By knowing the latest people's favorite trends, new business people have the convenience of promoting their brand. The Instagram posts trend can be known through the text classification method.
