Data Collection

We collect high-quality data across multiple data types, including text, speech & audio, image, and video, in a variety of scenarios.


Collect text data from various sources as requested by clients: e-commerce data, music titles, artist names, handwritten notes, abbreviations and acronyms, geographical locations, ads, magazines, textbooks, news, social media, and legal documents.

Speech & Audio

Collect speech data through speech transcription and Speech-to-Text (STT), whether with an unusual accent or a rare dialect, or in a special scenario: speech output by microphones/mobile phones/embedded devices, single/multi-person speech, near/far field speech, speech at recording studio/public places, indoor/outdoor speech, reading/speaking/conversation, etc.


Collect image data for specific scenarios: multi-category images, multi-scene images, faces, expressions, graphic symbols, home construction, traffic elements, and location-based images.


Collect video data for specific scenarios: videos of specified persons and actions, videos in specified environments, and aerial photography.

Data Annotation

Our data annotation service accurately annotates, classifies, and analyzes unstructured multilingual data needed to train machine learning applications to ensure accurate results: cleaning, extraction, and annotation at scale for text, speech, audio, image, video, and other special data.


Text transcription into phonemic or phonetic equivalent, semantic annotation, emotional tone annotation, parallel corpora annotation, text keywords, content classification, sentence structure, semantics, stem, and lexicon.

Speech & Audio

Speech transcription, speech screening, background environment noise, speaker role, as well as TTS accent, intonation, and rhythm.


Image classification, image tag classification, image relevance evaluation, image content extraction, invalid image filtering, image text extraction, and facial expression annotation.


Video segmentation, video transcription, behavioral trajectory, human expression, emotion, video quality screening, content moderation, and aerial photography.

Data Evaluation

ECI's data evaluation service is designed to help you improve the quality and accuracy of online information, optimize content moderation, and ensure search engine relevance.

Optimize content moderation

We protect your brand by assisting you in ensuring that comments, reviews and feedback left by users with Chatbots and other social media channels are free of hate speech or other malicious content.


If your Chatbot is built on mature data, we can help it create chat modes and trigger instant answers to frequently asked questions to respond to customers more quickly.

Social media

Want to know what your end users are saying about you on social networks? We can help you ensure that your users get the best experience and maintain loyalty to your brand.

Search relevance evaluation

Our customized solutions allow you to improve overall search relevance. Our services include the evaluation of specific search results and even the entire search engine results page.

Annotation Methods

Polyline Annotation

This is usually used to annotate lanes for self-driving vehicles to define the positions of linear objects precisely without excessive noise and white spaces.

Rectangle Annotation

This is the simplest image annotation type. A large volume of rectangle annotation data can train the model to recognize the objects you need.

Key-Point Annotation

It is used to track the movement trajectories of key points for statistical models (such as foot traffic calculation models for commercial sites) as well as gesture or facial recognition models.

Polygon Annotation

This annotation features higher precision to avoid visual model deviation caused by a large amount of white space and extra noise. Common use cases include robotic grabber, medical image recognition, satellite image recognition, etc.

Semantic Segmentation

As the most precise annotation method in image annotation, it involves labeling each pixel in an image, allowing you to make full use of limited data sources.

Image Classification

This is a very important data cleaning task, especially for image recognition-based applications. It enables you to classify an image according to its visual content, paving a way for more complex annotation tasks in later stages.
