🧠 Structured Text for NLP and LLMs

Named entity recognition, classification, relation extraction, intent and sentiment annotation: we transform raw text into structured labels for NLP pipelines, search systems and language models.

✍️ Human-Verified Annotation Quality

Guideline calibration, inter-annotator checks, adjudication and documented quality controls help us deliver consistent, traceable and training-ready text datasets.

Named Entity Recognition, Entity Linking and PII Annotation

Identify and label people, organizations, locations, dates, products, amounts and other domain-specific entities within text. We also support entity linking, nested entities, coreference and personally identifiable information (PII) annotation when the use case requires greater semantic depth.

⚙️ Process steps:

Choice of relevant categories (e.g. PERSON, ORGANIZATION, ORGANIZATION, LOCATION, DATE, PRODUCT, ...) and associated annotation rules

Cleaning, breaking down into relevant sentences or units, and possible anonymization of the content

Manual or assisted selection of text segments corresponding to entities, and assignment of corresponding labels

Cross-reading to verify the accuracy of the annotations and the consistency of the labeling criteria throughout the corpus

🧪 Practical applications:

Smart search engines — Better understanding of content and intentions through the extraction of key entities

Legal and medical documents — Automatic identification of sensitive entities (persons, pathologies, medications, etc.)

Monitoring and retrieving information — Automatic text analysis to detect trends, alerts or strategic information

Text Classification and Taxonomy Labeling

Assign one or more labels to documents, paragraphs, sentences or messages using a predefined taxonomy. We support single-label, multi-label, hierarchical and multilayer classification for large, diverse text corpora.

⚙️ Process steps:

Development of a set of relevant classes according to the use case (e.g. positive/negative/neutral, legal/marketing/technical, etc.)

Cleaning of textual data, removal of duplicates, linguistic normalization (punctuation, uppercase letters, special characters, ...)

Assigning categories to each document or sentence by human annotators or using pre-existing tools, with validation

Proofreading and quality control to ensure that the classification criteria are applied uniformly to the entire corpus

🧪 Practical applications:

Content moderation — Automatic filtering of inappropriate or off-topic messages on forums, social networks or chats

Sorting emails or tickets — Automated routing of incoming requests to the right departments or teams

Sentiment analysis — Assessment of the opinion expressed in customer reviews, surveys or online comments

Linguistic Annotation and Dependency Parsing

Annotate the linguistic structure of text at token, phrase and sentence level. Services include tokenization, lemmatization, part-of-speech tagging, morphology, dependency parsing, constituency, coreference and other language-specific structures.

⚙️ Process steps:

Breakdown of text into base units (words, sentences) to facilitate analysis

Attribution to each word of its grammatical label (e.g. noun, verb, preposition), taking into account the context

Detection of hierarchical structures: dependencies between words, nominal/verbal groups, subordinates, etc.

Proofreading and validation to correct markup errors and refine analysis in ambiguous or complex cases

🧪 Practical applications:

Indexing and intelligent search — Better understanding of requests and documents thanks to a detailed analysis of the sentence structure

Automatic text generation — Correct structuring of sentences produced by AI models

Morpho-syntactic labelling — Attribution to each token of its grammatical category, according to the local and global context

Intent, Sentiment, Emotion and Stance Annotation

Label what a user wants, how they feel and what position they express. We annotate intent, sentiment, emotion, tone, urgency, stance and conversational outcomes using label sets calibrated to your product and domain.

⚙️ Process steps:

Creation of a set of labels adapted to the use case

Cleaning and formatting of texts (or transcripts), anonymization if necessary, segmentation into annotated units

Allocation of labels by annotators according to defined instructions, with the possibility of multi-labelling (e.g.: request for help + frustration)

Cross-validation to ensure consistency of annotations, especially on subtle or ambiguous emotions

🧪 Practical applications:

Virtual assistants and chatbots — Understanding the intention to adapt responses and propose relevant actions

Reputation monitoring — Detection of emotional trends around a brand or a product

Customizing the user experience — Adapting the tone or content according to the perceived emotion

Multilingual translation workflow with English, Japanese, and French languages

Multilingual and Domain-Specific Text Annotation

Annotate text across languages, dialects and writing systems with native or fluent teams. We adapt taxonomies and guidelines to linguistic structure, local usage, cultural context, code-switching and domain-specific terminology rather than translating labels mechanically.

⚙️ Process steps:

Definition of the target languages, the expected level of granularity (morphological, semantic, syntactic...) and the specificities of each language (cultural sensitivity, writing, dialectal variants)

Cleaning and harmonization of data in different languages, coherent segmentation and adaptation to specific scripts (Latin, Arabic, Cyrillic, etc.)

Application of linguistic, semantic or contextual annotation instructions by linguists or annotators who know the native language

Cross-linguistic verification of the coherence and uniformity of annotations across different formats

🧪 Practical applications:

Machine translation systems — Creation of quality aligned corpora to improve the accuracy of translations

International chatbots — Development of virtual assistants capable of interacting with users in their native language

Comparative analysis between languages — Linguistic, sociolinguistic or sentimental studies on multilingual corpora

Text Annotation for LLM Training and Evaluation

Annotate and review text datasets used to fine-tune, evaluate and monitor language models. We label instructions, responses, factuality, relevance, reasoning quality, safety categories and domain metadata using project-specific rubrics and human review.

⚙️ Process steps:

Identify the targeted skills: text comprehension, fluid generation, logical reasoning, dialogue, translation, etc.

Gather data from a variety of sources (articles, forums, dialogues, legal databases, technical documents, etc.), ensuring their quality and linguistic and thematic diversity

Elimination of duplicates, correction of errors, filtering of sensitive or irrelevant content, formatting according to the requirements of the model (JSON, txt, XML, etc.)

Adding useful metadata (language, style, register, tone, intention, ...), or generating question/answer pairs, summaries, reasoning chains, etc.

🧪 Practical applications:

Pre-training of general-purpose LLMs — Creation of massive data sets for multilingual, multitasking or open models

RAG (Retrieval-Augmented Generation) — Creation of indexable corpora used to feed retrieval augmented generation systems

Ongoing evaluation of models — Use of evaluation sets from the training dataset to check performance after each iteration
