+### Dataset Summary
+The first gold standard Tamil-English code-switched, sentiment-annotated corpus containing 15,744 comment posts from YouTube.  This makes the largest general domain sentiment dataset for this relatively low-resource language with code-mixing phenomenon. The comment/post may contain more than one sentence but the average sentence length of the corpora is 1. Each comment/post is annotated with sentiment polarity at the comment/post level. This dataset also has class imbalance problems depicting real-world scenarios.
+
+### Supported Tasks and Leaderboards
+To identify sentiment polarity of the code-mixed dataset of comments/posts in Tamil-English collected from social media.
+
+### Languages
+Tamil-English code-switched.  The dataset contains all the three types of code-mixed sentences - Inter-Sentential switch, Intra-Sentential switch and Tag switching. Most comments were written in Roman script with either Tamil grammar with English lexicon or English grammar with Tamil lexicon. Some comments were written in Tamil script with English expressions in between. 
+
+
+## Dataset Structure
+
+### Data Instances
+
+An example from the Tamilmixsentiment train set looks as follows:
+```
+text										label
+Trailer late ah parthavanga like podunga	Positive 
+```
+
+### Data Fields
+
+- `text`: Tamil-English code-mixed comment.
+- `label`: list of the possible sentiments "Positive", "Negative", "Mixed_feelings", "unknown_state", "not-Tamil"
+
+### Data Splits
+
+The entire dataset of 15,744 sentences was randomly shuffled and split into three parts as follows:
+
+|                             | Tain   | Valid | Test |
+| -----                       | ------ | ----- | ---- |
+| Tamilmixsentiment           |  11335 |  1260 | 3149 |
+
+
+## Dataset Creation
+
+### Curation Rationale
+
+Sentiment analysis has become important in social media research (Yang and Eisenstein, 2017). Until recently these applications were created for high-resourced languages which analysed monolingual utterances. But social media in multilingual communities contains more code-mixed text.  Code-mixing is common among speakers in a bilingual speech community.  As English is seen as the language of prestige and education, the influence of lexicon, connectives and phrases from English language is common in spoken Tamil. Tamil has little annotated data for code-mixed scenarios. An annotated corpus developed for monolingual data cannot deal with code-mixed usage and therefore it fails to yield good results due to mixture of languages at different levels of linguistic analysis. Therefore this dataset of code-mixed Tamil-English sentiment annotated corpus is created.
+
+### Source Data
+
+#### Initial Data Collection and Normalization
+
+The data was scraped from Youtube. In total 184,573 sentences for Tamil from YouTube comments from the trailers of a movies released in 2019. Many of the them contained sentences
+that were either entirely written in English or code-mixed Tamil-English or fully written in Tamil. So we filtered out a non-code-mixed corpus based on language identification
+at comment level using the langdetect library. The comment is written fully in Tamil or English, we discarded that comment since monolingual resources are available for these languages. We also identified if the sentences were written in other languages such as Hindi, Malayalam, Urdu, Telugu, and Kannada. We preprocessed the comments by removing the emoticons and applying a sentence
+length filter. We want to create a code-mixed corpus of reasonable size with sentences that have fairly defined sentiments which will be useful for future research. Thus our filter removed sentences with less than five words and more than 15 words after cleaning the data. In the end we got 15,744 Tanglish sentences.
+
+#### Who are the source language producers?
+
+Youtube users
+
+### Annotations
+
+#### Annotation process
+
+Three steps complete the annotation setup. First, each sentence was annotated by two people. In the second step, the data were collected if both of them agreed. In the case of conflict, a third person annotated the sentence. In the third step, if all the three of them did not agree, then two more annotators annotated the sentences.
+
+#### Who are the annotators?
+
+Eleven volunteers were involved in the process. All of them were native speakers of Tamil with diversity in gender, educational level and medium of instruction in their school education.
