Text Analytics & NLP: Product Insights, Sentiment & Emerging Trends

Start with a product or business question

We define the decision before choosing a model. A footwear team may need to understand durability complaints, a retailer may be investigating emerging demand, and a customer-experience team may need to connect survey explanations to satisfaction scores. Each question calls for a different unit of analysis.

Source material can include chat transcripts, open-ended survey responses, reviews, support conversations, and other approved text. We retain product, channel, date, and audience context where it is available. That context helps distinguish a product issue from a delivery problem or an unrelated service interaction.

Connect tokens, phrases, and dependencies

Token analysis identifies useful terms and their frequency. Phrase and dependency analysis examine the surrounding language: which product is associated with an action, attribute, or complaint. This moves the work beyond counting isolated words and helps preserve what the customer actually meant.

In the historical Nike cleat example, related terms and dependency words were displayed alongside source comments about returns, breakage, and products falling apart. The source sentences distinguished faulty or deteriorating cleats from a separate failure to place a customized order. An analyst could move from a visual pattern to the original comment, score, and source field before deciding which product or ordering issue to investigate.

Evaluate sentiment in context

A comment can praise fit while criticizing durability. A sentence containing a word such as “not” can reverse or soften a sentiment that a keyword-only method would assign. We evaluate the scoring approach against the language and task rather than assume one general sentiment label explains the entire conversation.

Our Nike sentiment work was testing switch-polarity and shift-polarity approaches on negation-containing survey comments well before today’s mainstream generative AI tools. That history informs a practical evaluation process: review representative examples, inspect errors, compare methods, and report the population on which a score was measured. A narrow experimental result is not a current production benchmark.

Investigate emerging demand and product opportunities

Changes in customer language can identify a topic worth investigating before it is obvious in a conventional report. We compare product mentions, related attributes, requests, and their context across time windows and audience groups. Frequency alone is not a forecast: the analysis needs an appropriate denominator and a plausible commercial interpretation.

Historical On Beat work included coxcomb visualizations of leggings as an emerging product trend. The Nike presentation also recorded retro-product requests and emerging dance-related signals. These examples illustrate using customer language to form product hypotheses, then testing those hypotheses against other available evidence.

Explain purchasing drivers and audience differences

Product intelligence also asks why a customer chooses one item or brand. The Nike work examined comfort, fit, durability, price, familiarity, and the role of parents in purchasing decisions. Those questions connect text analysis to segmentation and product positioning rather than reduce the work to brand sentiment.

We compare the relevant groups and explain what the source can support. Conversation frequency, expressed preference, purchase intention, and completed purchases are different observations. Where appropriate data exists, text-derived features can be considered alongside survey measures, behavioral records, or statistical models to investigate the relationship.

Deliver an evidence trail people can use

Outputs can include product and issue taxonomies, scored comments, token and dependency views, trend comparisons, and a findings brief. Coxcomb, radial, table, or time-series views should be selected for the comparison they need to explain. Clear labels, counts, and source examples matter more than the novelty of a chart.

The handoff connects each finding to a decision: investigate a possible issue, review a product attribute, examine an emerging category, or improve the evidence collected. We distinguish an observed pattern from an interpretation and a recommendation, so the team can judge the conclusion and decide what to do next.
