Product / Multilingual NLP SDK

Full-pipeline multilingual NLP for AI, search and enterprise text systems

Bitext SDK turns raw enterprise text into cleaner linguistic input: segmented, normalized, lemmatized, decompounded, tagged and enriched before downstream systems consume it.

Full NLP pipeline
Multilingual normalization
Lemmatization
Decompounding
Entity extraction

Before Bitext

Raw text goes downstream with noise still inside it

• Fragmented word forms
• Hidden compounds
• Inconsistent entities
• Ambiguous tokens
• Domain vocabulary not normalized

After Bitext

Downstream systems receive cleaner linguistic input

• Words normalized to useful lemmas
• Compound terms made visible
• Linguistic tags added before AI
• Entity and phrase signals extracted
• Multilingual behavior handled by language-specific resources

SDK capabilities

One SDK. Multiple linguistic services.

The SDK combines lexical, morphological, syntactic and semantic processing so teams can prepare text before it reaches search, indexing, RAG, analytics or AI workflows.

Language identification

Detect the language so the right processing resources are applied

Sentence segmentation

Split text into sentences using language-specific rules

Tokenization

Split sentences into words and tokens before indexing or analysis

Word segmentation

Handle languages where words are not separated by spaces

Lemmatization

Return canonical forms so matching is based on meaning, not surface variants

Decompounding

Expose words hidden inside compounds for better search and retrieval

Spelling

Check whether words are spelled correctly in the target language

POS tagging

Add grammatical information that helps disambiguate meaning

Entity extraction

Detect names, organizations, places and special text patterns

Phrase extraction

Identify noun phrases, verb phrases and prepositional phrases

Parsing

Produce hierarchical sentence structures where deeper analysis is required

Why it matters for AI

Better input creates better downstream behavior

AI systems, search engines and retrieval pipelines all depend on the quality of the text they receive. Bitext improves the linguistic layer before those systems make decisions.

Search and indexing

More consistent matching

Normalize forms and expose compound terms before content is indexed or queried

RAG and retrieval

Cleaner retrieval signals

Give retrieval systems cleaner text units and stronger linguistic connections

Enterprise AI

Less linguistic noise

Reduce raw-text noise before automation, classification, extraction or model pipelines consume the content

Customizable by design

Adapt the pipeline to your domain, vocabulary and taxonomy

Enterprise text is domain-specific. Product names, technical vocabulary, regulatory terms, internal taxonomies and industry entities vary from customer to customer.

Bitext can be tailored to business context by adding custom entity types, taxonomies, domain recognition or additional linguistic resources.

Custom entity types
Domain terminology
Internal taxonomies
Business vocabulary
Multilingual expansion
Deterministic rules

The Hidden Signal in Millions of News Articles That Reveals How Global Narratives Form

The Experiment
We tested this idea using the Leipzig English News corpora from the Wortschatz Project at Leipzig University. We analyzed datasets from 2023, 2024 and 2025.

Across these datasets, the pipeline processed roughly:

2 million raw news articles
400K articles after topical filtering
From these documents the pipeline extracted:

millions of entity mentions
tens of millions of co-mention relationships
To focus on economic and technology narratives, documents were filtered using the IPTC Media Topics taxonomy, keeping only:

Economy, Business and Finance
Science and Technology

Why LLMs Are the Wrong Tool for Enterprise-Grade Entity Extraction

Large Language Models are powerful systems for language generation and reasoning.
However, when they are used for entity extraction in enterprise environments, they introduce instability where reliability is required.
Entity extraction is not about creativity or interpretation. It is infrastructure. In production systems, entities must be extracted in a way that is consistent, repeatable, and stable over time.

Tagging consistency is essential to ensure that training is smooth. Contradictions and inconsistencies not only decrease accuracy but also generate hidden costs in MLOps when trying to debug and fix errors. We often take this consistency for granted, but that is rarely the case, not only in these datasets but also in any other manual tagging work.

Consistency starts with having a solid and clear definition of what an entity is. Typically, if not always, that’s not the case.

And knowledge graphs are built using automatic data extraction tools: not only entity extraction but also concept extraction and relationships among entities or concepts.

German & Korean Retrieval Fails Without Proper Decompounding

German and Korean do not break retrieval because they are unusually complex; they break retrieval because most systems still treat complex words as monolithic strings. When compounds and eojeols remain opaque, search engines cannot align queries with documents—even when they contain the same meaning. Any team building multilingual search, vector search or RAG must incorporate reliable decompounding as a foundational step to avoid systematic retrieval failures.

The Moment to Pay Attention to Hybrid NLP (Symbolic + ML)

Problem. There’s broad consensus today: LLMs are phenomenal personal productivity tools — they draft, summarize, and assist effortlessly.
But there’s also growing recognition that they’re still not ready for enterprise-grade deployment.

Using Public Corpora to Build Your NER systems

Rationale. NER tools are at the heart of how the scientific community is solving LLM issues using GraphRAG and NodeRAG architectures.

LLMs need knowledge graphs to control hallucinations and make them more solid for enterprise-level use.

And knowledge graphs are built using automatic data extraction tools: not only entity extraction but also concept extraction and relationships among entities or concepts.

Open-Source Data and Training Issues

As described in our previous post “Using Public Corpora to Build Your NER systems”, we are going to highlight areas where public datasets like OntoNotes or CoNLL can be improved. We will provide some tips on how to avoid these issues, whenever possible, using (semi-)automatic techniques.

Why Semantic Intelligence Is the Missing Link in Active Metadata and Data Governance

The new Forrester Wave™: Data Governance Solutions, Q3 2025 makes one thing clear: governance is no longer about static catalogs. Vendors are moving fast into Active Metadata and Agentic AI, with features like lineage, observability, policy enforcement, and marketplaces for data assets.

Bitext NAMER: Slashing Time and Costs in Automated Knowledge Graph Construction

The process of building Knowledge Graphs is essential for organizations seeking to organize, structure, and extract actionable insights from their data. However, traditional methods of constructing Knowledge Graphs are often slow, expensive, and complex, requiring significant expertise and manual effort. Bitext NAMER changes the game by automating key steps in the Knowledge Graph creation process, making it faster, more cost-effective, and accessible for businesses of all sizes.

Multilingual Named Entity Recognition for Knowledge Graphs: Supporting 70+ Languages with Precision

In the era of data-driven decision-making, Knowledge Graphs (KGs) have emerged as pivotal tools for structuring, organizing, and interconnecting vast amounts of information. From enhancing search engine capabilities to powering AI-driven insights, KGs rely heavily on extracting, interpreting, and linking data elements with precision. At the core of this process lies Named Entity Recognition (NER), event extraction, and relationship mapping, foundational technologies for enabling robust knowledge management. Bitext’s NER solution, NAMER, is uniquely positioned to support the growing needs of KG companies, offering unparalleled features that address common industry challenges.
