What We Improve / Entity Extraction

Extract business signals from unstructured multilingual text

Bitext NAMER SDK extracts and normalizes entities from unstructured text as part of a robust enterprise NLP pipeline. It provides deterministic, explainable entity extraction for AI-driven systems, semantic search, RAG, knowledge graphs and compliance workflows.

Named entities
Concept extraction
Domain terminology
Custom taxonomies
15 production-ready languages

The hidden problem

Business entities are buried in messy language

• Names, organizations, products and places appear in many forms
• Domain concepts are mixed with generic text
• Special text patterns can be missed or misclassified
• Multilingual entity behavior varies by market
• LLM-only extraction can be hard to reproduce consistently

The Bitext fix

Use deterministic linguistic extraction before downstream AI

• Detect common entity types across multilingual text
• Normalize terminology and concepts before routing or indexing
• Add customer-specific entities and taxonomies
• Extract structured signals for graph, search or compliance workflows
• Keep extraction close to the enterprise NLP layer
• Use C, Python and Java bindings for integration

What Bitext extracts

From raw text to structured business signals

Bitext combines deep morphosyntactic analysis, POS tagging, configurable rule pipelines and semantic disambiguation layers to identify the entities and concepts that matter to enterprise systems.

01 / Detect

Find entities in context

Identify people, places, organizations, brands, account-like values, phone numbers and other special text patterns.

02 / Normalize

Reduce entity variation

Use linguistic normalization and dictionaries to reduce noisy surface variation across languages and document types.

03 / Customize

Adapt to business vocabulary

Add domain-specific entities, controlled taxonomies and custom concept classes for enterprise workflows.

Entity and concept coverage

Extract more than names

Entity extraction becomes more useful when it can identify business-relevant signals, not just generic people and places.

People and names

Person names and name-like expressions inside unstructured text

Organizations and brands

Companies, institutions, brands and organizational references

Places and locations

Countries, cities, regions and location references

Special text patterns

Phone numbers, account-like values, URLs and structured text forms

Domain concepts

Business objects, internal concepts and industry-specific terms

Custom entity types

Customer-specific categories aligned to your taxonomy or workflow

Multilingual and customizable

Entity extraction must understand the domain, not only the language

Bitext can combine multilingual entity dictionaries, linguistic analysis and custom business vocabularies so extraction fits your enterprise context.

Custom ontologies
Taxonomy-based tagging
Domain-specific entities
Multilingual dictionaries
Annotated corpora support
Cross-language alignment

Where extracted entities go

Feed structured signals into the systems that need them

Entity extraction is most valuable when it becomes infrastructure for downstream search, compliance, graph, data governance and AI workflows.

Search and filtering

Use entities as facets, filters and ranking signals

Knowledge graphs

Create cleaner candidates for graph nodes and relationships

Document intelligence

Extract structured fields from reports, contracts, claims and records

AI workflows

Provide structured signals for routing, retrieval, classification or enrichment

Turn your text into structured business signals

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.
