Model Description

MENTHOS-LogParsing is a token-classification model fine-tuned from answerdotai/ModernBERT-base for structured field extraction from raw logs. It uses a maximum sequence length of 256.

Intended Use

• BIO-style token labeling on log lines.
• Useful for extracting fields like request URL, status, error level, timestamp, etc.

Label Space

Training code defines BIO labels (plus special ignored/padding handling), including:

• B-request_url, I-request_url
• B-status
• B-error_level, I-error_level
• B-error_message, I-error_message
• B-time_received, I-time_received
• B-remote_host, I-remote_host
• and additional request-header related labels

The full token-label mapping is defined in the training code.

Training Data

Trained on the MENTHOS log-parsing dataset.

Limitations

• Label matching is based on tokenized substring alignment from structured columns.
• Domain shift in log formats can reduce extraction quality.

Opis modela

MENTHOS-LogParsing je model za token klasifikacijo, naučen iz answerdotai/ModernBERT-base, za ekstrakcijo strukturiranih polj iz surovih log zapisov. Uporablja maksimalno dolžino zaporedja 256.

Namen uporabe

• BIO označevanje tokenov v log vrsticah.
• Uporabno za polja kot so URL zahteve, status, error level, časovni žig ipd.

Prostor oznak

Skripta učenja definira BIO oznake (ter posebne oznake za ignoriranje/padding), npr.:

• B-request_url, I-request_url
• B-status
• B-error_level, I-error_level
• B-error_message, I-error_message
• B-time_received, I-time_received
• B-remote_host, I-remote_host

Celotno mapiranje je definirano v učni kodi.

Učni podatki

Učenje je potekalo na MENTHOS log-parsing datasetu.

Omejitve

• Ujemanje oznak temelji na poravnavi tokeniziranih podnizov.
• Pri drugačnih log formatih se lahko kakovost ekstrakcije zmanjša.
