# How should we rationalize our tag scheme?

Many common topics on the site have multiple overlapping tags covering the same or similar areas. The specific tags I have in mind are:

Risk

• risk
• risk-management
• risk-models
• coherent-risk-measure
• risk-neutral
• risk-neutrality

Research/reference request

• research
• reference
• reference-request

Models

• model
• models
• modeling
• data-model

Options

• option
• options
• option-pricing
• option-price
• option-strategies
• black-scholes
• black-scholes-formula
• implied-volatility
• greeks
• delta-neutral
• gamma

Equity

• stock
• stocks
• stock-prices
• stock-selection
• equity

Fixed Income

• fixed-income
• bonds
• interest-rates

Data

• data
• market-data
• database
• databases
• data-model
• tick-data
• historical-data
• real-time-data

At the moment, the system only seems to allow moderators to propose tag synonyms, since few if any of us have enough reputation in each tag to propose tag synonyms ourselves.

I'm not sure how to organize the discussion. Perhaps we can set up a chat time to discuss this. Perhaps each answer should propose a set of synonyms in a given topic, and others can up-vote to show their approval for that set of synonyms. Some other SE sites often have a few rather verbose tag names, with almost all popular variants automatically redirecting to those. I think we should adopt the same practice here.

• Looks like we should add a tag for "random matrix theory" – Ram Ahluwalia Jan 22 '12 at 16:12

• I'm with Louis here. stocks-equity and bonds-fixed-income seem too convoluted. Consensus here is we're aiming at a professional user, so IMO layman's terms should be avoided. As a convenience for readers, we could use layman's tag synonyms instead. And another thing from a quick perusal - I would drop finance tag completely, it seems redundant for a Quantitative Finance site. – Karol J. Piczak Sep 9 '11 at 10:08
