Final answer:
The SPARQL 1.1 Query Results CSV and TSV Formats are serialization formats for SPARQL query results, enabling easy use with common data-processing tools, but not suitable for visualization, ontology modeling, or semantic triple extraction.
Step-by-step explanation:
The SPARQL 1.1 Query Results CSV and TSV Formats provide serialization formats for query results. These formats are used to represent the results of SPARQL queries in a structured way that can be easily imported into tools that handle these common file formats. CSV (Comma-Separated Values) and TSV (Tab-Separated Values) are particularly useful for the output of SELECT and ASK queries. They do not visualize RDF graphs, support ontology modeling, or facilitate semantic triple extraction; those tasks require different tools and formats unique to those purposes. CSV and TSV are simple, plain text formats that can be read by most data-processing tools, making it easier for users to manipulate the results of their SPARQL queries using standard software.
