Capabilities:

• Connector ecosystem (ERP, CRM, financial systems, cloud billing, communication tools)

• Semantic search engine

• Document extraction and contract parsing

• Knowledge graph construction

• Unified representation store

The Search Layer is ChordianAI’s data acquisition and semantic retrieval engine. It aggregates information from fragmented enterprise systems, normalizes it into structured representations, and enables intelligent access through semantic understanding rather than rigid schemas.

The Search Layer performs three core functions:

1. Enterprise Data Ingestion – connecting to operational systems and collecting structured/unstructured data.

2. Semantic Retrieval and Understanding – enabling natural-language and concept-driven access to information.

3. Knowledge Structuring – constructing knowledge graphs and unified representations that preserve context, relationships, and provenance.

2.2.1 Data Ingestion and Acquisition

Purpose

To reliably acquire data from all critical enterprise systems—financial, operational, communication, cloud infrastructure, and business applications—while maintaining consistency, governance, and traceability.

Process

Step 1 Connector Initialization

The Search Layer activates native connectors for:

• ERP systems (SAP, Oracle NetSuite)

• CRM platforms (Salesforce, HubSpot)

• Financial and billing systems

• Cloud billing APIs (AWS, GCP, Azure, OCI)

• Productivity tools (Google Workspace, Slack, Teams)

• DevOps tools (GitHub, GitLab, Jira)

• Data warehouses (Snowflake, BigQuery, Redshift)

• Storage layers (S3, GCS, Azure Blob)

Each connector ensures secure authentication, rate limit handling, and incremental data extraction.

Step 2 Multi-Modal Data Collection

The layer ingests:

• structured tables

• logs and telemetry

• time-series streams

• PDFs and contracts

• emails and messages

• configuration files

• cost and usage reports

• change events from APIs

Step 3 Data Normalization and Cleaning

Ensures consistency across diverse sources through:

• schema alignment

• entity deduplication

• timestamp standardization

• noise and error correction

• document OCR and text normalization

Step 4 Metadata and Provenance Tracking

Every ingested object is tagged with:

• source system

• acquisition timestamp

• version history

• access rights

• lineage references

This enables auditability and secure downstream use.

2.2.2 Semantic Search and Retrieval

Purpose

To convert fragmented enterprise information into a semantically searchable corpus, enabling users and agents to retrieve information using natural language, conceptual queries, or agent-to-agent communication.

Process

Step 1 Semantic Indexing

The Search Layer builds embeddings and semantic indices for:

• documents

• tables

• log entries

• system entities (employees, tools, licenses, resources, suppliers)

• contract sections

• workflows and past decisions

• financial and operational metrics

Step 2 Natural-Language Query Understanding

Queries such as:

“Which teams are overspending on cloud compute?”

“Show underutilized licenses past 3 months.”

“Find suppliers with late deliveries.”

are parsed into structured semantic forms understood by ChordianAI’s agents.

Step 3 Cross-System Retrieval

Semantic search executes across heterogeneous data simultaneously, retrieving relevant objects even if they originate from different systems or data types.

Step 4 Ranking, Relevance, and Context Injection

The Search Layer ranks results using:

• text similarity

• relational graph proximity

• temporal patterns

• business priorities

Step 5 Data Assembly for Downstream Agents

Retrieved information is packaged for possible consumption by the Analyze/Optimize/Orchestrate layers, including:

• structured feature sets

• document subsets

• entity clusters

• historical sequences

• contract clauses

• anomaly indicators

2.2.2a GraphRAG Retrieval & Grounded Answering

Purpose
“To generate grounded, explainable answers by combining semantic retrieval with graph traversal over explicit entities, relationships, and provenance — while enforcing source permissions and role-aware access.”

• Pipeline

  1. Candidate retrieval (hybrid): embeddings + full-text retrieve relevant chunks, entities, and documents

  2. Graph expansion: traversal expands context around retrieved nodes (teams, people, projects, customers, systems), selecting the minimal relevant subgraph

  3. Permission filtering: filter nodes/chunks against source ACLs and tenant policies before generation

  4. Grounded generation: LLM produces an answer with strict citations to source spans and explainable reasoning paths

  5. UI outputs: tabbed/federated results + entity drill-down (people/org, documents, systems) + provenance view (source + timestamp + confidence)

Operational guarantees
“GraphRAG responses are deterministic in what sources were eligible (permissions), traceable (citations + provenance), and auditable (query logs + retrieval traces).”

2.2.3 Knowledge Structuring and Representation

Purpose

To transform raw and semantically indexed data into coherent domain structures—knowledge graphs, entity networks, and unified representation stores—so that enterprise context becomes directly usable for intelligent automation.

Process

Step 1 Knowledge Graph Construction

The Search Layer builds dynamic knowledge graphs mapping:

• people → tools → usage → cost centers

• systems → APIs → dependencies

• contracts → obligations → renewal dates

• products → suppliers → lead times

• resources → workloads → performance metrics

• models → API calls → cost and latency

Edges capture relationships such as ownership, frequency, hierarchy, influence, or causality.

Step 2 Unified Representation Store

All structured and unstructured knowledge is stored in a unified, cross-modal representation layer that supports:

• vector search

• relational queries

• temporal queries

• graph queries

• document retrieval

• composite reasoning

This unified store allows every agent to access the same consistent representation of enterprise knowledge.

Step 3 Contextual Feature Extraction

The layer automatically derives:

• time features (seasonality, periodicity)

• operational features (usage spikes, outages)

• finance features (spend acceleration, anomalies)

• organizational features (team size, ownership, activity level)

• knowledge features (document themes, clause risks)

These are essential for forecasting, optimization, and agent reasoning.

Step 4 Persistent Context for Workflows

Knowledge is enriched with:

• past workflows

• execution traces

• prior decisions

• learned patterns

enabling the platform to build workflows that improve over time.

2.2.4 Core Capabilities Summary

Connector Ecosystem: Enables secure, governed ingestion from all primary enterprise systems.

Semantic Search Engine: Provides language-driven, context-aware retrieval across all modalities.

Document Extraction and Contract Parsing: Transforms unstructured documents into structured, queryable objects.

Knowledge Graph Construction: Builds relational and causal maps of enterprise operations.

Unified Representation Store: A single, coherent layer enabling all ChordianAI agents to reason over consistent and enriched knowledge.

2.2.5 Role in ChordianAI Architecture

The Search Layer is intelligent automation that ensures:

• Data is reliable and unified

• Semantic retrieval is accurate

• Enterprise knowledge is structured

• Workflows receive clean, contextual inputs

• Downstream analysis and optimization operate on high-quality information
