Llinguistic-summarization

Description

Program to perform linguistic aggregation of the database content and then generate linguistic summaries of the database.

Earthquake Data 2010-2023 Latest

The dataset utilized is the "Earthquake Data 2010-2023", which describes earthquakes detected from 2010 to 2023, limited to the years 2022-2023 and records containing complete information about two types of earthquakes - local earthquakes and those of short duration. Each record contains 22 attributes, from which 11 numerical attributes were selected, and linguistic variables were created based on them.

Attributes

• time: The time at which the earthquake occurred, in ISO 8601 format (yyyy-mm-ddThh:mm:ss.mmmZ).
• latitude: The latitude of the earthquake epicenter in decimal degrees.
• longitude: The longitude of the earthquake epicenter in decimal degrees.
• depth: The depth of the earthquake hypocenter in kilometers.
• mag: The magnitude of the earthquake on the Richter scale.
• gap: The largest azimuthal gap between azimuthally adjacent stations (in degrees).
• dmin: The closest distance to the earthquake epicenter on the earth's surface (in degrees).
• rms: The root-mean-square of the residuals of the earthquake location solution (in seconds).
• horizontalError: The horizontal error ellipse (semi-major axis) of the earthquake location solution (in kilometers).
• depthError: The depth error ellipse (semi-major axis) of the earthquake location solution (in kilometers).
• magError: The standard error of the earthquake magnitude.

Measures of Linguistic Summaries Quality.

• T1 – degree of truth
• T2 – degree of imprecision
• T3 – degree of coverage
• T4 – degree of accuracy
• T5 – length of the summary
• T6 – degree of quantifier imprecision
• T7 – degree of relative quantifier cardinality
• T8 – degree of relative summarizer cardinality
• T9 – degree of qualifier imprecision
• T10 – degree of relative qualifier cardinality
• T11 – length of the qualifier

Example of linguistic summary

• Above 6000 earthquakes have group of continents: Asia.
