ACCURATE!! 2026!!
What is an agent? - correct answer-Anything that can be viewed as perceiving its environment
through percepts and acting upon that environment through actuators.
What is de-identification in terms of privacy? - correct answer-eliminating personally identifying
information so that medical researchers can use the data to advance the common good.
What is k-anonymity - correct answer-A property used to protect individual identities.
A database is k-anonymized if every record in the database is indistinguishable from at least k-1
other records
what is aggregate querying - correct answer-offers a privacy-preserving alternative by focusing on
group-level trends instead of individual records.
what is differential privacy - correct answer-guarantees that the output of a data analysis (or AI
model) looks almost the same whether or not any one person's data is included. Works by
adding randomness (noise) to queries
what is federated learning - correct answer-a machine learning technique that allows AI models to
be trained across many devices or servers holding local data samples, without ever sharing the raw
data.
It's a privacy-preserving approach that keeps data decentralized and on the user's device.
what is secure aggregation - correct answer-a privacy preserving technique that allows multiple
parties to collaboratively compute an aggregate (sum or avg) of their individual data without
revealing their raw data.
Ontology - correct answer-this is a way to formally represent knowledge by defining concepts,
relationships, and properties.
,14 August 2026
what is an observation sentence in terms of an ontology? - correct answer-this is a statement or
assertion about a fact or observation in each domain. involves a subject, predicate, and an
object.
what is a knowledge representation language? - correct answer-a formal system used to describe
ontologies. helps show the structure, limits, and meanings of concepts, relationships and
properties.
Are ontologies good for organizing knowledge? - correct answer-Yes
what is ontology alignment? - correct answer-the process of connecting and combining different
ontologies to make sure concepts, relationships and properties make sense together.
what are properties in an ontology - correct answer-these are the features or traits connected to a
concept or class.
what is reasoning in an ontology - correct answer-means using logical rules to figure out new things
or make conclusions based on the information.
what are relationships in an ontology - correct answer-these show the links between concepts or
classes.
help to understand the ontology better
what is event calculus - correct answer-a method used to describe and understand events and how
they change over time.
what are the objects of event calculus? (3) - correct answer-1. events
2. fluents
3. time points
fluents in terms of event calculus - correct answer-these are the changing conditions or states that
can vary over time
, 14 August 2026
objects in terms of event calculus - correct answer-these are the specific items or entities involved in
those situations
What is the fluent and what is the object: a smart thermostat - correct answer-object = the
thermostat fluent = the temperature in the house
propositional attitudes - correct answer-describe how agents relate to mental objects such as
beliefs, knows, wants, and informs
what is modal logic used for? - correct answer-used to model knowledge, belief, time, obligation,
and possibility; things classical logic cannot easily express.
It forms the backbone of many reasoning systems in knowledge representation, multi-agent systems,
planning, and natural language understanding.
what is linear temporal logic - correct answer-a type of modal logic used to reason about how truths
evolve over linear time; that is, a single sequence of states or events ordered from past to future.
semantic networks - correct answer-these are graphical tools used to visualize and reason about
knowledge
what do semantic networks represent categories and their relationships through? - correct
answernodes (object or categories)
Links (relationships between the networks)
existential graphs - correct answer-these were an early form of semantic networks
key features of semantic networks? (4) - correct answer-multiple inheritance
procedural attachment default values overriding
description logics - correct answer-this provides a formal language for defining and combining
categories, with a focus on the logical relationships between them
what is description logics designed to handle? - correct answer-designed to handle complex category
