요약	Aspect-based review mining is a natural-language-processing technique that turns large volumes of consumer reviews into feature-level opinion summaries useful for product and brand insight. Rather than scoring a review as merely positive or negative overall, it identifies the specific product features, or aspects, that customers comment on, the battery life, screen, price, customer service, and so on, and determines the sentiment expressed toward each. Minqing Hu and Bing Liu's 2004 KDD paper, Mining and Summarizing Customer Reviews, defined the canonical pipeline: extract the frequently mentioned features, find the opinion words associated with them, decide each opinion's polarity, and produce a feature-by-feature summary of how many reviewers praised or criticized each aspect. This granularity is what makes the method valuable to marketers, because a four-star product can hide a beloved design and a hated battery, and only feature-level analysis reveals it. Applied across a brand's reviews, it yields a structured map of product strengths and weaknesses straight from the voice of the customer. It scales qualitative listening to thousands or millions of reviews that no team could read by hand.	Means-end chain analysis explains consumer choice by linking the concrete attributes of a product to the consequences of using it and ultimately to the personal values those consequences serve. Jonathan Gutman's 1982 model proposed that consumers categorize products by the desirable consequences they deliver, and that these consequences are valued because they help attain higher-order life values, so a chain runs attribute to consequence to value. Laddering, formalized by Thomas Reynolds and Jonathan Gutman, is the interviewing technique that uncovers these chains by repeatedly asking why a feature matters until the respondent reaches the underlying values. The resulting ladders are content-coded into attributes, consequences, and values, then summarized in an implication matrix counting how often each element leads to another. Applying a cutoff to that matrix yields a hierarchical value map (HVM), a network showing the dominant attribute-consequence-value pathways for the category. The approach reveals not just what consumers want but why, providing a values-grounded foundation for positioning and advertising strategy.
