The keyword phrase "sep lai 11 rue buffault 75009 paris france" functions grammatically as a proper noun. A proper noun is a name used to identify a specific and unique person, place, or organization. In this context, the entire string operates as a single, unique identifier for a specific entity at a precise geographic location, distinguishing it from all other entities or locations.
A detailed grammatical breakdown shows the phrase is a complex noun phrase composed of several nominal components that work in concert. The head of the phrase is "sep lai," which is itself a proper noun, likely the name of a person or a business entity. The subsequent elements"11 rue buffault" (the street address), "75009" (the postal code), "Paris" (the city), and "France" (the country)are locative adjuncts. These adjuncts function as appositives, meaning they are placed next to the head noun to further specify and identify it. While individual words within the phrase have their own parts of speech (e.g., "11" is a numeral/determiner, "rue" is a common noun), their collective function is to form one singular, specific proper noun.
Recognizing the entire keyword phrase as a proper noun is the crucial point for its application. In content strategy, search engine optimization (SEO), and natural language processing (NLP), treating the string as a single named entity is essential. This ensures that search algorithms and data systems correctly interpret it as a reference to one unique subject, rather than as a disjointed series of unrelated terms. This classification dictates how the term should be tagged, indexed, and analyzed for relevance and context.
