Linguistic Annotation Services
Make your AI/ ML model able to process natural language (any human language) with our linguistic annotation services. It’s a sub-part of our NLP (Natural Language Processing) program where we help machines understand human language. We train your language-based AI models to respond naturally like a human does.

Remember the Georgetown-IBM Experiment?
This 1954 experiment was the first of its kind successful attempt where machines translated 60 Russian sentences into English.
That’s a pioneer project of NLP development. Time has changed, technology updated, and our needs have also grown. With the application of natural language processing,
Linguistic Annotation – Basic Understanding
Linguistic annotation is simply a process of labeling different textual data to help machine learning models understand human languages. It labels text data from audio and visual files and digs deeper to understand linguistic patterns. With this training, AI systems can comprehend human languages fluently like humans; and also, respond like humans through the use of accurate language.

3 Basic Steps to NLP
I
The machine interprets meaning as per the algorithm
II
The Machine responds to what users ask
III
The Machine produces output in the form of a language that users can understand

Quality of training data is everything as it determines the success of a machine learning project. The volume of quality data basically determines the accuracy of the outputs of the AI models. Let us help you with quality-trained data for NLP-based AI model development. Develop computer vision, channel textual content, and perform other metrics utilizing our annotation services.

Named Entity Recognition
Find and classify entities such as names, dates, phrases of high values, etc. We work on classifying nouns to identify names from textual data. As a team, we are working with linguistics experts for this task.
Text Classification
Find content similarities in group texts (tagging topics or adding anti-spam filters). With a vast knowledge of the language, our experts perfectly find similar texts and then connect similar words to help your ML model understand the relation.


Keyphrase Tagging
Annotate keywords and key phrases from text and label them as per your linguistic AI model development. We choose keyphrases from text data with our years of expertise in linguistic annotation work.
Coreference Annotation
Link all relevant key entities in your text and establish a relationship between them with our coreference annotation work. It provides you with a compact form of data where you can find all related data through tags.
OCR & Intelligent Data Capture
Using IDC and smart OCR we help you annotate texts for your computer vision project. We make text copies editable and annotate them for computer vision models.
Audio to Text Transcription
Convert spoken speech into editable text documents utilizing phonetic features. We also annotate texts using discourse structure after conversion.


Phonetic Annotation
Annotate each element of the spoken language (tone of the language, stress between words, natural pauses between words and sentences, etc) using our phonetic annotation methods. Besides audio, we deal with video data as well.
Sentiment Analysis
Texts have subjective meanings and contain emotions. We perform sentiment assessment to extract subjective meanings, opinions, attitudes, and of course, emotions from text data and annotate them.
Synaptic Parsing
Highlight and annotate the relationship between different parts of a sentence to help ML algorithms understand the use of word syntax and morphemes in phrases and sentences. It makes our ML models grammatically advanced and reduces grammatical errors in outputs.

Our Pillars of Strength Delivering Language Annotation Services

State-of-the-art labeling system
Each text element of your data is annotated by our experienced professionals. They have proper training and expertise in labeling text data in large volumes.
Grammatical Expertise
Annotating text elements demands vast grammatical knowledge and subject expertise. Fortunately, our team consists of language experts who have a wide grammar sense.
Covering 80+ Languages
Besides ENGLISH, we are covering more than 80 other languages for our annotation work. For example, we are handling language annotation projects in Spanish, French, Portuguese, Japanese, etc languages.
Scale Up Operation
Currently, we have a team strength of 300+ in-house data annotators. We can quickly scale up your annotation project. However, our service is commitment-free, you can scale down at any time.
Bias-Free Language Assessment
Language itself is a subjective matter but we try our level best to make the annotation work bias-free. We avoid skewing data and our cognitive biases while working on these projects.
Client Experiences


We find managing a lot of import-export documents by following all rules and regulations very difficult. Therefore, we wanted to have an outsourcing partner that could perform all document management tasks for us. Eventually, we found InputiX is very promising in their document management services. They organized all our documents in their respective folders within a specific period and handed all folders to us before the deadline.
