What We Improve / Semantic Search & RAG

Give RAG cleaner evidence before retrieval starts

Semantic search and RAG depend on retrievable evidence. Bitext SDK improves the linguistic layer before embeddings, vector search, hybrid retrieval or grounding pipelines consume the text.

Retrieval preparation
Cleaner chunks
Normalized terms
Compound visibility
Grounding support

The hidden problem

RAG can only ground answers in what retrieval can find

• Relevant evidence may be hidden by morphology
• Compound-heavy languages can bury important terms
• Chunks may contain noisy or inconsistent variants
• Multilingual retrieval can behave unevenly across languages
• Better generation cannot fix missing evidence

The Bitext fix

Improve the language layer before semantic retrieval

• Normalize query and document language before retrieval
• Expose compound terms before chunking or indexing
• Add linguistic signals that support hybrid search
• Make multilingual text more consistent across markets
• Give RAG cleaner evidence to ground answers

Where Bitext fits in RAG

A linguistic preparation layer before retrieval

Bitext does not replace embeddings or vector search. It improves the text they receive, especially in multilingual, domain-specific and compound-heavy environments.

01 / Before chunking

Clean the source text

Apply language detection, segmentation, normalization and decompounding before documents become retrievable units.

02 / During indexing

Store better linguistic signals

Enrich indexable content with lemmas, compound components, entities or phrase signals depending on the workflow.

03 / At retrieval time

Improve query-document connection

Normalize user queries and retrieve evidence through cleaner linguistic connections before generation happens.

Hybrid retrieval advantage

Semantic search still benefits from lexical intelligence

Embeddings are powerful, but enterprise search often requires exact evidence, domain vocabulary, multilingual control and stronger query-to-document connections. Bitext improves the lexical side of hybrid retrieval.

Dense retrieval

Meaning-level similarity

Useful for semantic proximity, paraphrase and broader context matching

Bitext linguistic layer

Language-aware evidence

Improves exact, normalized and compound-aware matching before retrieval and ranking

Hybrid search

Stronger combined retrieval

Combines semantic similarity with cleaner lexical and linguistic signals

What improves

Cleaner retrieval, stronger grounding and more reliable answers

Bitext helps RAG systems retrieve better evidence by making enterprise text more consistent, searchable and linguistically explicit before the model sees the context.

Enterprise knowledge bases
Multilingual RAG
Support automation
Regulated document search
Technical documentation
AI assistants

Expected impact

Reduce retrieval noise before it becomes answer noise

When retrieval misses the right evidence or retrieves noisy context, generation quality suffers. Bitext improves the linguistic input before retrieval and grounding happen.

Better evidence retrieval

Retrieve relevant chunks that raw token matching or noisy input may miss

Cleaner hybrid search

Strengthen lexical matching alongside vector similarity

More stable multilingual RAG

Apply language-specific normalization across multilingual content

Stronger grounding

Give answer generation better context to work from

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.
