Opinion Analyst

Overview

OpinionAnalyst wraps 666ghj/BettaFish, a public-opinion analysis library built for high-throughput sentiment mining. The specialist surfaces three core capabilities — sentiment scoring, stance detection, and bias measurement — as callable tools within the OSS Agent Lab pipeline.

Capabilities

• sentiment: Document-, sentence-, and aspect-level sentiment scoring with a continuous score in [-1.0, 1.0].
• opinion_analysis: Holistic opinion mining that combines sentiment with aspect extraction for nuanced understanding.
• stance_detection: Determines whether the author supports, opposes, or is neutral toward a named entity or claim.
• bias_measurement: Measures political, emotional, framing, source-attribution, and confirmation bias; returns per-dimension scores and human-readable flags.

Tools

Tool	Description	Side Effects
analyze_sentiment	Score sentiment (positive/negative/neutral) with confidence and aspects	None
detect_stance	Classify stance (support/oppose/neutral) toward a target	None
measure_bias	Score bias across configurable dimensions, return flags	None

Usage

Python API

import asyncio
from agents.specialists.opinion_analyst.agent import OpinionAnalystSpecialist
from oss_agent_lab.contracts import Intent, Query, SpecialistRequest

specialist = OpinionAnalystSpecialist()

request = SpecialistRequest(
    intent=Intent(action="sentiment", domain="opinion", confidence=0.9),
    query=Query(user_input="The new policy is an outstanding step forward."),
    specialist_name="opinion_analyst",
)

result = asyncio.run(specialist.execute(request))
print(result.result)
# {'sentiment': {'sentiment': 'positive', 'confidence': 0.65,
#                'aspects': [], 'overall_score': 0.2}}

Stance Detection

request = SpecialistRequest(
    intent=Intent(
        action="stance",
        domain="opinion",
        confidence=0.9,
        parameters={"target": "climate policy"},
    ),
    query=Query(user_input="I strongly support climate policy reforms."),
    specialist_name="opinion_analyst",
    tools_requested=["detect_stance"],
)
result = asyncio.run(specialist.execute(request))

Bias Measurement

request = SpecialistRequest(
    intent=Intent(
        action="bias",
        domain="opinion",
        confidence=0.9,
        parameters={"dimensions": ["political", "emotional"]},
    ),
    query=Query(user_input="The radical left regime is destroying our nation!"),
    specialist_name="opinion_analyst",
    tools_requested=["measure_bias"],
)
result = asyncio.run(specialist.execute(request))

CLI

oss-lab run opinion_analyst "The product quality is excellent and worth every penny."
