In the contemporary digital landscape, social media has emerged as a prominent means of communication and information dissemination, offering a rapid outreach to a broad audience compared to traditional communication methods. Unfortunately, the escalating prevalence of abusive language and hate speech on these platforms has become a pressing issue. Detecting and addressing such content on the Internet has garnered considerable attention due to the significant impact it has on individuals. The advent of deep learning has facilitated the use of pre-trained deep neural network models for text classification tasks. While these models demonstrate high performance, some exhibit a substantial number of parameters. In the DravidianLangTech@EACL 2024 task, we opted for the Distilbert-base-multilingual-cased model, an enhancement of the BERT model that effectively reduces the number of parameters without compromising performance. This model was selected based on its exceptional results in the task. Our system achieved a commendable Macro F1 score of 0.6369%.

This study goes into our team’s active participation in the Hate and Offensive Language Detection in Telugu Codemixed Text (HOLDTelugu) shared task, which is an essential component of the DravidianLangTech@EACL 2024 workshop. The ultimate goal of this collaborative work is to push the bounds of hate speech recognition, especially tackling the issues given by codemixed text in Telugu, where English blends smoothly. Our inquiry offers a complete evaluation of the task’s aims, the technique used, and the precise achievements obtained by our team, providing a full insight into our contributions to this crucial linguistic and technical undertaking.

Tewodros@DravidianLangTech 2024: Hate Speech Recognition in Telugu Codemixed Text

Over the past few years, research on hate speech and offensive content identification on social media has been ongoing. Since most people in the world are not native English speakers, unapproved messages are typically sent in code-mixed language. We accomplished collaborative work to identify the language of code-mixed text on social media in order to address the difficulties associated with it in the Telugu language scenario. Specifically, we participated in shared task on the provided dataset by the DravidianLangTech Organizer for the purpose of identifying hate and non hate content. The assignment is to classify each sentence in the provided text into two predetermined groups: hate or non-hate. We developed a model in Python and selected a BERT multilingual to do the given task. Using a train-development data set, we developed a model, which we then tested on test data sets. An average macro F1 score metric was used to measure the model's performance. For the task, the model reported an average macro F1 of 0.6151.

Lidoma@DravidianLangTech 2024: Identifying Hate Speech in Telugu Code-Mixed Texts: A BERT Multilingual Approach

Hate speech is communication, often oral or written, that incites, stigmatizes, or incites violence or prejudice against individuals or groups based on characteristics such as race, religion, ethnicity, gender, sexual orientation, or other protected characteristics. This usually involves expressions of hostility, contempt, or prejudice and can have harmful social consequences. Among the broader social landscape, an important problem and challenge facing the medical community is related to the impact of people's verbal expression. These words have a significant and immediate effect on human behavior and psyche. Repeating such phrases can even lead to depression and social isolation. In an attempt to identify and classify these Telugu text samples in the social media domain, our research LSTM and the findings of this experiment are summarized in this paper, in which out of 27 participants, we obtained 8th place with an F1 score of 0.68.

Global communication has been made easier by the emergence of online social media, but it has also made it easier for "fake news," or information that is misleading or false, to spread. Since this phenomenon presents a significant challenge, reliable detection techniques are required to discern between authentic and fraudulent content. The primary goal of this study is to identify fake news on social media platforms and in Malayalam-language articles by using LSTM (Long Short-Term Memory) model. This research explores this approach in tackling the DravidianLangTech@EACL 2024 tasks. Using LSTM networks to differentiate between real and fake content at the comment or post level, Task 1 focuses on classifying social media text. To precisely classify the authenticity of the content, LSTM models are employed, drawing on a variety of sources such as comments on YouTube. Task 2 is dubbed the FakeDetect-Malayalam challenge, wherein Malayalam-language articles with fake news are identified and categorized using LSTM models. In order to successfully navigate the challenges of identifying false information in regional languages, we use lstm model. This algoritms seek to accurately categorize the multiple classes written in Malayalam. In Task 1, the results are encouraging. LSTM models distinguish between orignal and fake social media content with an impressive macro F1 score of 0.78 when testing. The LSTM model’s macro F1 score of 0.2393 indicates that Task 2 offers a more complex landscape. This emphasizes the persistent difficulties in LSTM-based fake news detection across various linguistic contexts and the difficulty of correctly classifying fake news within the context of the Malayalam language

Tayyab@DravidianLangTech 2024:Detecting Fake News in Malayalam LSTM Approach and Challenges

Social media platforms have become increasingly popular and are utilized for a wide range of purposes, including product promotion, news sharing, accomplishment sharing, and much more. However, it is also employed for defamatory speech, intimidation, and the propagation of untruths about particular groups of people. Further, hateful and offensive posts spread quickly and often have a negative impact on people; it is important to identify and remove them from social media platforms as soon as possible. Over the past few years, research on hate speech detection and offensive content has grown in popularity. One of the many difficulties in identifying hate speech on social media platforms is the use of code-mixed language. The majority of people who use social media typically share their messages in languages with mixed codes, like Telugu–English. To encourage research in this direction, the organizers of DravidianLangTech@EACL-2024 conducted a shared task to identify hateful content in Telugu-English code-mixed text. Our team participated in this shared task, employing three different models: Xlm-Roberta, BERT, and Hate-BERT. In particular, our BERT-based model secured the 14th rank in the competition with a macro F1 score of 0.65.

As part of the Fourth Workshop on Speech, Vision, and Language Technologies for Dravidian Languages (DravidianLangTech-2024) at EACL, this paper presents the shared challenge of multimodal sentiment analysis, abusive language detection and hate speech detection in Dravidian languages. Through this shared work, researchers worldwide can submit their models for three crucial social media data analysis challenges in Dravidian languages - sentiment analysis, abusive language detection, and hate speech detection. This aim is to build models for deriving fine-grained sentiment analysis from multimodal data in Tamil and Malayalam, identifying abusive and hate content from multimodal data in Tamil. Three modalities make up the multimodal data: text, audio, and video. YouTube videos were gathered to create the datasets for the tasks. Thirty-none teams took part in the competition. However, only two teams, though, turned in their findings. The macro F1-score was used to assess the submissions.

Findings of the Shared Task on Multimodal Social Media Data Analysis in Dravidian Languages (MSMDA-DL)@DravidianLangTech 2024

In the digital age, identifying fake news is essential when fake information travels quickly via social media platforms. This project employs machine learning techniques, including Random Forest, Logistic Regression, and Decision Tree, to distinguish between real and fake news. With the rise of news consumption on social media, it becomes essential to authenticate information shared on platforms like YouTube comments. The research emphasizes the need to stop spreading harmful rumors and focuses on authenticating news articles. The proposed model utilizes machine learning and natural language processing, specifically Support Vector Machines, to aggregate and determine the authenticity of news. To address the challenges of detecting fake news in this paper, describe the Machine Learning (ML) models submitted to ‘Fake News Detection in Dravidian Languages” at DravidianLangTech@EACL 2024 shared task. Four different models, namely: Naive Bayes, Support Vector Machine (SVM), Random forest, and Decision tree.

The importance of sentiment analysis in online community research is growing. These technologies only looked at single utterances and were created for high-resource languages until recently. Nonetheless, multilingual communities' social media platforms have seen an increase in code-mixed writing. Our research focuses on sentiment analysis in texts with mixed Tamil and English codes. supervised learning techniques using annotated data outperform features based on lexical attributes, such as word dictionaries and parts of speech tagging. Our project's decision tree technique is essential since it makes it possible to classify sentiments in the code-mixed Tamil-English.
