KB Query Examples

Basic Usage

from kb_query import KBQueryEngine

# Initialize
engine = KBQueryEngine('path/to/ontology.ttl')

# Simple query
result = engine.query("meetings with John Smith")
print(result['sparql'])

Query Patterns

Meeting Queries

# By attendee
engine.query("meetings with John Smith")
engine.query("meetings attended by Sarah Chen")

# By time
engine.query("meetings from last week")
engine.query("meetings today")

# By tag
engine.query("meetings tagged projects/web")

Todo Queries

# By assignee
engine.query("todos assigned to me")
engine.query("John's todos")

# By status
engine.query("incomplete todos")
engine.query("overdue todos")

# By date
engine.query("todos due tomorrow")

Complex Queries

# Multiple filters
engine.query("meetings with John from last week")
engine.query("incomplete todos assigned to Sarah")

# With limits
engine.query("top 5 recent meetings")
engine.query("latest 10 daily notes")
