That matters as businesses use AI for work that moves beyond productivity assistance and toward decisions. In the accessible opening of her Communications of the ACM article, Esther Shein writes: “Because context shapes how the AI understands and generates outputs, AI agents need to understand what people mean—not just what they say.” The listing is dated September 30, 2026; its full article text is not available in the accessible source, so the practical retrieval guidance below is separate background, not a summary of Shein’s full argument.

Why context changes an AI response
A request rarely contains every fact needed to answer it well. Its intended meaning may depend on earlier discussion, the task at hand, or information specific to a business. A system that follows only the surface wording can miss that meaning; a system supplied with relevant context has a better basis for interpreting the request and generating an appropriate output.

That is the central framing in the accessible excerpt of Shein’s article: as AI takes on a larger role in enterprise decision-making, it must understand what people mean, not merely parse what they say. The excerpt establishes that framing, but not specific enterprise examples, statistics, or implementation recommendations.

How businesses can supply relevant context
For an AI system that retrieves documents to inform its response, context depends partly on what retrieval brings back. The Applied LLMs guide recommends judging retrieved material by relevance, information density, and detail: does it bear on the request, contain useful information rather than noise, and provide enough substance to support an answer?

#1 Best Overall
Retrieval methods have different strengths. The guide distinguishes keyword retrieval, which suits exact terms, from embedding-based retrieval, which can find semantically related material even when wording differs. Hybrid retrieval combines the two.
| Approach | Useful when | Trade-off to assess |
|---|---|---|
| Keyword retrieval | The request contains an exact name, acronym, or identifier. | It is designed for precise matches; wording differences can make related material harder to find. |
| Embedding retrieval | Relevant material may use synonyms or related concepts rather than the request’s exact wording. | Assess whether the semantic matches are genuinely relevant to the task. |
| Hybrid retrieval | A workflow needs exact matches as well as coverage of paraphrases and related concepts. | Check that both kinds of results contribute useful, sufficiently detailed context. |
These are general retrieval practices described by the Applied LLMs guide, not recommendations verified in the full ACM article. They offer a practical way to think about the context an AI receives: retrieval should match the request’s language and meaning, and the returned information should be useful enough to support the response.

What is established about Shein’s article
The accessible listing identifies Esther Shein’s Communications of the ACM article as published September 30, 2026, and reproduces its opening context framing. It does not expose the full article, so its further arguments, examples, named cases, and statistics cannot be confirmed from that listing. The ACL proceedings page is broad research background, not evidence for claims about Shein’s article. ACL Anthology.
