A structured answer is more than just text — it is an information unit that begins with a direct response, followed by layered context. In semantic SEO, this approach respects contextual borders, ensuring that each section serves a single intent ...

A substitute query occurs when a search engine reformulates part of the original query to improve retrieval accuracy. Instead of treating the input literally, it replaces words with close alternatives that better reflect user intent. For example, a search for ...

A Categorical Query is a user search input that explicitly or implicitly references a category, such as a product type, topical domain, or knowledge class. Example: “best DSLR cameras 2025” → category = DSLR cameras. Example: “lawyer in Karachi” → ...

A Query Rewrite is the automatic transformation of a user’s query into a modified or alternative form to improve relevance, recall, or precision in search results. Example: “cheap hotel NY” → rewritten to “affordable hotels in New York City”. Example: ...

Query breadth describes how many plausible subtopics, categories, and SERP formats a query can legitimately trigger. The broader the query, the higher the ambiguity and the greater the need for refinement. Broad example: “laptops” → brands, use-cases, prices, OS, reviews, ...

A candidate answer passage is a short, coherent text segment retrieved from a document that the system believes may contain the answer to a user’s question. It’s produced before extraction or final ranking, acting as a bridge between initial retrieval ...

At the heart of SRL lies the idea that meaning emerges through relationships between entities. For example, in “The teacher explained the lesson to the students in the classroom”: Predicate → explained Agent → teacher Theme → lesson Recipient → ...

At its essence, distributional semantics builds vector space models (VSMs) of meaning: Each word is represented as a vector in a high-dimensional space. Words that appear in similar contexts (neighbors, documents, or syntactic environments) are placed close together. The geometry ...

Index partitioning is a structural design choice where the index is split into independent or semi-independent units. These partitions may be based on ranges of values, hash functions, categorical keys, or even semantic clusters. In relational databases, index partitioning aligns ...

The Central Entity represents the main subject of a query, document, or cluster of documents. It is the entity most semantically relevant and most strongly connected to other entities. In search engines, identifying the central entity allows the system to ...
