	"text": "Traditional media content distribution channels such as television, radio or newspapers are monitored and scrutinized for their content. Nevertheless, social media platforms on the Internet opened the door for people to contribute, leave a comment on existing content without any moderation. Although most of the time, the internet users are harmless, some produce offensive content due to anonymity and freedom provided by social networks. Due to this freedom, people are becoming creative in their jokes by making memes. Although memes are meant to be humorous, sometimes it becomes threatening and offensive to specific people or community. On the Internet, a troll is a person who upsets or starts a hatred towards people or community. Trolling is the activity of posting a message via social media that is intended to be offensive, provocative, or menacing to distract which often has a digressive or off-topic content with the intent of provoking the audience (Bishop, 2013; Bishop, 2014 ; Mojica de la Vega and Ng, 2018; Suryawanshi et al., 2020) . Despite this growing body of research in natural language processing, identifying trolling in memes has yet to be investigated. One way to understand how meme varies from other image posts was studied by Wang and Wen (2015) . According to the authors, memes combine two images or are a combination of an image and a witty, catchy or sarcastic text. In this work, we treat this task as an image classification problem. Due to the large population in India, the issue has emerged in the context of recent events. There have been several threats towards people or communities from memes. This is a serious threat which shames people or spreads hatred towards people or a particular community (Kumar et al., 2018; Rani et al., 2020; Suryawanshi et al., 2020) . There have been several studies on moderating trolling, however, for a social media administrator memes are hard to monitor as they are region-specific. Furthermore, their meaning is often obscure due to fused image-text representation. The content in Indian memes might be written in English, in a native language (native or foreign script), or in a mixture of languages and scripts (Ranjan et al., 2016; Chakravarthi et al., 2018; Jose et al., 2020; Priyadharshini et al., 2020; Chakravarthi et al., 2020a; Chakravarthi et al., 2020b) . This adds another challenge to the meme classification problem. In Figure 1 , Example 1 is written in Tamil with two images and Example 2 is written in English and Tamil (Roman Script) with two images. In the first example, the meme is trolling about the \"Vim dis-washer\" soap. The information in Example 1 can be translated into English as \"the price of a lemon is five Rupees\", whereby the image below shows a crying person. Just after the crying person the text says \"The price of a Vim bar with the power of 100 Lemon is just 10 Rupees\". This is an example of opinion manipulation with trolling as it influences the user opinion about products, companies and politics. This kind of memes might be effective in two ways. On the one hand, it is easy for companies and political parties to gain popularity. On the other hand, the trolls can damage the reputation of the company name or political party name. Example 2 shows a funny meme; it shows that a guy is talking to a poor lady while the girl in the car is looking at them. The image below includes a popular Tamil comedy actor with a short text written beneath \"We also talk nicely to ladies to get into a relationship\". Even though there is a widespread culture of memes on the Internet, the research on the classification of memes is not studied well. There are no systematic studies on classifying memes in a troll or not-troll category. In this work, we describe a dataset for classifying memes in such categories. To do this, we have collected a set of original memes from volunteers. We present baseline results using convolutional neural network (CNN) approaches for image classification. We report our findings in precision, recall and F-score and publish the code for this work at https: //github.com/sharduls007/TamilMemes.",

	"text": "A troll meme is an implicit image that intents to demean or offend an individual on the Internet. Based on the definition \"Trolling is the activity of posting a message via social media that tend to be offensive, provocative, or menacing (Bishop, 2013; Bishop, 2014 ; Mojica de la Vega and Ng, 2018)\". Their main function is to distract the audience with the intent of provoking them. We define troll memes as a meme, which contains offensive text and non-offensive images, offensive images with non-offensive text, sarcastically offensive text with non-offensive images, or sarcastic images with offensive text to provoke, distract, and has a digressive or off-topic content with intend to demean or offend particular people, group or race. Figure 2 shows examples of trolling memes, Example 3 is trolling the potato chip brand called Lays. The translation of the text is \"If you buy one packet of air, then 5 chips free\", with its intention to damage the company's reputation. Figure 2 illustrates examples of not-troll memes. The translation of Example 4 would be \"Sorry my friend (girl)\". As this example does not contain any provoking or offensive content and is even funny, it should be listed in the not-troll category. As a troll meme is directed towards someone, it is easy to find such content in the comments section or group chat of social media. For our work, we collected memes from volunteers who sent them through WhatsApp, a social media for chatting and creating a group chat. The suspected troll memes then have been verified and annotated manually by the annotators. As the users who sent these troll memes belong to the Tamil speaking population, all the troll memes are in Tamil. The general format of the meme is the image and Tamil text embedded within the image. Most of the troll memes comes from the state of Tamil Nadu, in India. The Tamil language, which has 75 million speakers, 1 belongs to the Dravidian language family (Rao and Lalitha Devi, 2013; Chakravarthi et al., 2019a; Chakravarthi et al., 2019b; Chakravarthi et al., 2019c) and is one of the 22 scheduled languages of India (Dash et al., 2015) . As these troll memes can have a negative psychological effect on an individual, a constraint has to be in place for such a conversation. In this work, we are attempting to identify such troll memes by providing a dataset and image classifier to identify these memes.",

	"text": "A related research area is on offensive content detection. Various works in the recent years have investigated Offensive and Aggression content in text (Clarke and Grieve, 2017; Mathur et al., 2018; Nogueira dos Santos et al., 2018; Galery et al., 2018) . For images, Gandhi et al. (2019) deals with offensive images and non-compliant logos. They have developed a computer-vision driven offensive and non-compliant image detection algorithm that identifies the offensive content in the image. They have categorized images as offensive if it has nudity, sexually explicit content, abusive text, objects used to promote violence or racially inappropriate content. The classifier takes advantage of a pre-trained object detector to identify the type of object in the image and then sends the image to the unit which specializes in detecting objects in the image. The majority of memes do not contain nudity or explicit sexual content due to the moderation of social media on nudity. Hence unlike their research, we are trying to identify troll memes by using image features derived by use of a convolutional neural network. Hate speech is a subset of offensive language and datasets associated with hate speech have been collected from social media such as Twitter (Xiang et al., 2012) , Instagram (Hosseinmardi et al., 2015) , Yahoo (Nobata et al., 2016) , YouTube (Dinakar et al., 2012) . In all of these works, only text corpora have been used to detect trolling, offensive, aggression and hate speech. Nevertheless, for memes, there is no such dataset. For Indian language memes, it is not available as to our knowledge. We are the first to develop a meme dataset for Tamil, with troll or not-troll annotation.",

It is still a popular method for classifying images and uses residual learning which connects low-level and high-level representation directly by skipping the connections in-between. This improves the performance of ResNet by diminishing the problem of vanishing gradient descent. It assumes that a deeper network should not produce higher training error than a shallow network. In this experiment, we used the ResNet architecture with 176 layers. As it was trained on the ImageNet task, we removed the classification (last) layer and used GlobalAveragePooling in place of fully connected layer to save the computational cost. Later, we added four fully connected layers with the classification layer which has a sigmoid activation function.This architecture is trained with or without pre-trained ImageNet weights.",

The main purpose of MobileNet is to optimize convolutional neural networks for mobile and embedded vision applications. It is less complex than ResNet in terms of number of hyperparameters and operations. It uses a different convolutional layer for each channel, this allows parallel computation on each channel which is Depthwise Separable Convolution. Later on the features extracted from these layers have been combined using the pointwise convolution layer. We used MobileNet to reduce the computational cost and compare it with the computationally intensive ResNet.",

Images from the Flickr30k dataset are used to balance the not-troll class in the TamilMemes + ImageNet + Flickr1k variation.

This variation has relatively poor results when compared with the other three variations in ResNet. While precision at identifying the troll class for the ResNet baseline does not vary much, we get better precision at classifying troll memes in the TamilMemes variation. This shows that the ResNet model trained on just Tamil memes has a better chance at identifying troll memes. The scenario is different in the case of the MobileNet variations. On the one hand, we observed less precision at identifying the troll class for the TamilMemes variation. On the other hand, we see improvement in precision at detecting trolls in the TamilMeme + ImageNet variation. This shows that MobileNet can leverage transfer learning to improve results. The relatively poor performance of MobileNet on the TamilMeme variation shows that it can not learn complex features like ResNet does to identify troll memes. For ResNet, the trend in the macro averaged score can be seen increasing in TamilMemes + ImageNet and TamilMemes + ImageNet + Flickr1k variations when compared to the TamilMemes variation. The TamilMemes + ImageNet + Flickr30k variation shows a lower macro averaged score than that of the TamilMemes + ImageNet + Flickr1k variation in both MobileNet and ResNet. Overall the precision for troll class identification lies in the range of 0.28 and 0.37, which is rather less than that of the not-troll class which lies in the range of 0.64 and 0.68. When we train ResNet in class imbalanced data in TamilMemes and TamilMemes + ImageNet + Flickr30k variations, results shows that the macro-averaged score of these variations are not hampered by the class imbalance issue. While for same variations MobileNet shows poor macro-averaged precision and recall score when compared with other variations. This shows that MobileNet is more susceptible to class imbalance issue than ResNet.",

Further, the same image can be used with different text to mean different things, potentially making the task more complicated.",
