Standardised Reputation Measurement

TL;DR

This paper introduces a formal, time-based reputation index derived from mined opinions, extending sentiment definitions to quantify reputation, and discusses practical data collection and the existence of unexpressed positive sentiment.

Contribution

It presents a novel formal definition of reputation as a time-based index incorporating mined opinions and explores the quantification of unexpressed positive sentiment.

Findings

Reputation can be formalized as a time-based index.

Unexpressed positive sentiment exists and can be quantified.

Practical data procurement methods are discussed.

Abstract

Well-defined formal definitions for sentiment and opinion are extended to incorporate the necessary elements to provide a formal quantitative definition of reputation. This definition takes the form of a time-based index, in which each element is a function of a collection of opinions mined during a given time period. The resulting formal definition is validated against informal notions of reputation. Practical aspects of data procurement to support such a reputation index are discussed. The assumption that all mined opinions comprise a complete set is questioned. A case is made that unexpressed positive sentiment exists, and can be quantified.
