Model Details

Overview

This model is a fine-tuned version of microsoft/mdeberta-v3-base adapted for the Query Distillation task in Spanish. It operates via Token Classification, analyzing natural language queries and labeling each word to decide whether it should be kept as a key search term or discarded as syntactic noise.

It is specifically designed as an ultra-lightweight and fast filter to be integrated into RAG pipelines and document search systems (like Paperless-ngx) orchestrated through LEMoE.

• —Developed by: lemoe.link
• —Model type: Encoder-based Transformer (Token Classification)
• —Language(s): Spanish (es)
• —License: AGPL
• —Base model: microsoft/mdeberta-v3-base

Architecture and Operation

Since it is an Encoder model, it does not generate new text (it is not autoregressive). Instead, it assigns a binary weight to each input token:

• —LABEL_1 (Keep): Entities, keywords, subjects, and services.
• —LABEL_0 (Drop): Prepositions, generic action verbs, polite phrases, and connectors.

Intended Uses and Limitations

Direct Use

• —Keyword Extraction: Converting long queries ("búscame la factura de Iberdrola por favor") into optimized search strings ("factura Iberdrola").
• —Conversational Interfaces: Acting as a silent middleware layer between natural language user requests and strict lexical search engines.

Recommended Execution Environments

• —CPU Inference: Being a base-sized Encoder model, it is optimized to run with millisecond latencies (typically < 100ms) on standard x86 processors, ideal for HomeLab clusters or low-power nodes.
• —Microservices: Perfect for being served via local APIs in Docker containers, without requiring GPU acceleration for personal or small-network traffic volumes.

Limitations

• —The model does not rewrite words (it does not correct spelling mistakes by generating new tokens, although its embeddings tolerate certain typos when evaluating the token's root).
• —It is optimized exclusively for the Spanish language.
