What We Improve / Search Relevance

Improve search relevance before ranking starts

Search quality depends on the linguistic quality of the text being indexed and queried. Bitext SDK normalizes words, exposes compounds and adds language-aware signals before your search engine, ranking layer or AI system tries to match anything.

Decompounding
Query normalization

The hidden problem

Most search stacks still receive raw noisy text

• Inflected forms are treated as different signals
• Compound words hide important terms
• Stemming can connect words that should stay separate
• Multilingual behavior is inconsistent across languages
• Ranking is forced to compensate for bad input
The Bitext fix

Normalize meaning before search tries to match

• Lemmatization preserves canonical word meaning
• Decompounding makes hidden terms searchable
• Language-specific resources reduce noisy matches
• Query and document text can be normalized consistently
• Ranking starts from cleaner linguistic evidence

How Bitext improves search relevance

Create better search signals before indexing and querying

Bitext acts as a linguistic relevance layer. It prepares both documents and queries so the search engine receives cleaner terms, better normalized forms and richer signals.

01 / Normalize

Connect word forms by meaning

Lemmatization connects forms like singular/plural or conjugated verbs to useful canonical forms without relying on crude surface chopping.

02 / Expose

Make compound terms visible

Decompounding splits compound-heavy language forms into searchable components so relevant evidence is not hidden inside long words.

03 / Enrich

Add linguistic context

POS, morphology, entities and phrase signals can help downstream systems distinguish better matches from noisy ones.

Beyond basic analyzers

Stemming helps. Linguistic normalization is smarter.

Stemming can be useful, but it does not understand morphology or meaning. Bitext uses language-aware linguistic processing so search systems can connect terms more accurately.

Basic stemming

Cuts word endings without understanding meaning

• Can connect unrelated words
• Can distort proper names and brands
• Often varies in quality across languages
• Leaves compounds unresolved
Bitext linguistic normalization

Uses language resources to preserve meaning

• Maps forms to dictionary lemmas
• Handles language-specific morphology
• Exposes compound components
• Works as a stable preprocessing layer before ranking

Where Bitext fits

Add a linguistic relevance layer before search and ranking

Bitext does not replace the search engine. It improves the text that search engines, vector databases, ranking models and AI retrieval systems consume.

Index-time normalization
Query-time normalization
Search analyzer enrichment
Compound-heavy language handling
Multilingual relevance
RAG retrieval preparation

Expected impact

Cleaner language signals for more reliable relevance

Search relevance improves when the system can recognize related forms, avoid false connections and retrieve evidence that raw token matching would miss.

Better recall

Find relevant documents even when query and document forms differ

Fewer false positives

Avoid noisy matches caused by overly crude word reduction

More multilingual consistency

Apply language-aware processing across markets instead of one-size-fits-all analyzers

Cleaner AI retrieval

Prepare better evidence before semantic search or RAG retrieves context

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.
