Dataset Composition
Distribution of text samples across the six Filipino NLP benchmark datasets
🔴 Hate Speech Dominant
The hate speech detection dataset is the largest component with ~12,000 annotated samples, reflecting research priority on online safety
📊 Balanced Benchmark
The benchmark suite covers classification, sentiment, stance detection, and toxicity - enabling comprehensive model evaluation
🌐 Multilingual Coverage
Combined dataset size of 42,000+ samples makes this one of the largest publicly available Filipino NLP resources
Hate Speech Categories
Breakdown of hate speech types found in Filipino social media text
🔴 Race & Gender Lead
Race/ethnicity and gender-based hate speech together account for nearly half of all hateful content, mirroring global patterns in online toxicity
📊 Political Hate Speech
Political hate speech is a major category, driven by highly polarized Philippine political discourse especially during election cycles
Text Length Distribution
Character count distribution reveals posting behavior patterns across Filipino social media
📊 Average Length
The average Filipino social media post is 112 characters - significantly shorter than the typical 280-character limit
📈 Most Common Range
28.4% of all texts fall in the 50-100 character range, indicating preference for brief, punchy communication
📉 Long Posts Rare
Only 3.6% of texts exceed 280 characters, suggesting most Filipino social media interaction is concise and direct
Most Frequent Words (Hate vs Non-Hate)
Linguistic markers that distinguish hateful from non-hateful Filipino text
🔴 Hate Speech Markers
Hate speech texts are dominated by Filipino profanity ("bobo", "gago", "tanga", "ulol") and English insults ("stupid"). These words serve as strong lexical indicators for classification models.
🟢 Non-Hate Markers
Non-hateful text features positive Filipino words ("maganda" - beautiful, "salamat" - thank you) alongside English positive terms ("love", "happy"), reflecting the bilingual nature of Filipino online expression.
Code-Switching Analysis
Language mixing patterns in Filipino social media reveal Taglish dominance
🔀 Taglish Dominant
Tagalog-English code-switching ("Taglish") is the most common language pattern, reflecting natural bilingual communication in Philippine social media
🇵🇭 Pure Tagalog
Pure Tagalog represents the second largest group, common in community-focused discussions and emotional expression
📊 NLP Challenge
Other Philippine languages (Cebuano, Ilocano, etc.) present additional challenges for NLP models trained primarily on Tagalog and English
Dengue Tweet Sentiment
Sentiment analysis of Filipino tweets about dengue reveals public health communication patterns
ℹ️ Information Sharing
The largest category is informational tweets - Filipinos actively share dengue prevention tips, outbreak updates, and hospital information during epidemics
😟 Anxiety & Fear
Worried/anxious tweets form the second largest group, spiking during outbreak peaks and reflecting public fear about the Dengvaxia controversy
Fake News Detection Results
Model performance comparison on the Filipino fake news classification benchmark
🏆 Best Performer
Filipino BERT achieves the highest accuracy at 87.2%, demonstrating the value of language-specific pre-training for Filipino text
📊 Transfer Learning Gap
Pre-trained transformer models outperform TF-IDF baseline by up to 15.1 percentage points, showing deep learning advantages for Filipino NLP
🔬 Multilingual Models
mBERT achieves competitive results despite not being Filipino-specific, suggesting cross-lingual transfer from related languages
Emotion Detection Distribution
Distribution of emotions expressed in Filipino social media text
😄 Joy Dominates
Joy is the most frequently expressed emotion, consistent with the generally optimistic and humor-driven nature of Filipino online culture
😠 Anger Second
Anger is the second most common emotion, often triggered by political posts and social issues. This correlates strongly with hate speech patterns.
Hashtag Frequency Analysis
Most frequently used hashtags reveal the political nature of Filipino social media discourse
🏛️ Political Dominance
Five of the top seven hashtags are political in nature (#NasaanAngPangulo, #LeniKiko2022, #BBMSara, #DuterteLegacy), reflecting how deeply politics permeates Filipino social media discourse.
🦠 COVID-19 Impact
#COVID19PH ranks third overall, showing how the pandemic dominated Filipino online conversation during the dataset collection period (2020-2023) and intersected with political discussions.
Mention Patterns
@-mention frequency distribution reveals direct engagement behavior
📊 Low Direct Engagement
68% of tweets contain zero @-mentions, indicating that most Filipino social media posts are broadcasts rather than directed conversations
💬 Single Mentions
22% contain exactly one mention, typically replies or call-outs. Posts with 3+ mentions (4%) are often part of coordinated campaigns or group conversations.
Text Complexity Metrics
Comparing linguistic complexity between hate speech and non-hate speech texts
📊 Lower Vocabulary Diversity
Hate speech shows significantly lower vocabulary diversity (0.42 vs 0.71), relying on repetitive insults and limited word choices
🔠 More Caps Usage
Hate speech texts use ALL CAPS at 3.2 times the rate of non-hate texts, reflecting heightened emotional expression and aggression
🤬 Profanity Rate
Profanity appears 8.6 times more frequently in hate speech, making it one of the strongest single-feature predictors for classification
Profanity & Toxicity Indicators
Profanity rates across different content categories in the dataset
⚠️ Hate Speech Toxicity
Nearly half of all hate speech samples contain explicit profanity, making lexical filtering an effective first-pass detection method for Filipino text
📊 Political Profanity
Political discussion has the second highest profanity rate at 28.4%, reflecting the intense and often vulgar nature of online political discourse in the Philippines
Temporal Posting Patterns
When Filipinos post on social media - hourly distribution reveals usage habits
🌙 Evening Peak
The primary posting peak occurs between 8-10 PM, when Filipinos are home from work and school, accounting for 22% of all posts
☀️ Lunch Rush
A secondary peak at 12-2 PM (15% of posts) coincides with lunch breaks - a common time for browsing social media in the Philippines
😴 Dead Hours
Activity drops to just 4% during early morning hours (2-6 AM), the lowest engagement window for Filipino social media
