1. Definition
Cognitive State is a Personal Status Factor representing the internal state of an Entity such as “surprised” or “interested”.
2. Functional Requirements
Cognitive State can be expressed via several Modalities: Text, Speech, Face, and Gestures. (Other Modalities, such as body posture, may be handled in future MPAI Versions.)
Within a given Modality, Cognitive State can be analysed and interpreted via various Descriptors. For example, when expressed via Speech, the elements may be expressed through combinations of such features as prosody (pitch, rhythm, and volume variations); separable speech effects (such as degrees of voice tension, breathiness, etc.); and vocal gestures (laughs, sobs, etc.).
Cognitive State is represented by a standard set of labels and associated semantics by two tables:
- A Label Set Table containing descriptive labels relevant to the Factor in a three-level format:
- The CATEGORIES column specifies the relevant categories using nouns (e.g., “AN-GER”).
- The GENERAL ADJECTIVAL column gives adjectival labels for general or basic la-bels within a category (e.g., “angry”).
- The SPECIFIC ADJECTIVAL column gives more specific (sub-categorised) labels in the relevant category (e.g., “furious”).
- A Label Semantics Table providing the semantics for each label in the GENERAL AD-JECTIVAL and SPECIFIC ADJECTIVAL columns of the Label Set Table. For example, for “angry” the semantic gloss is “emotion due to perception of physical or emotional damage or threat.”
Table 1 gives the standardised three-level Basic Cognitive State Label Set.
Table 1 – Basic Cognitive State Label Set
COGNITIVE CATEGORIES | GENERAL ADJECTIVAL | SPECIFIC ADJECTIVAL |
AROUSAL | aroused/excited/energetic | cheerful playful lethargic sleepy |
ATTENTION | attentive | expectant/anticipating thoughtful distracted/absent-minded vigilant hopeful/optimistic |
BELIEF | credulous | sceptical |
INTEREST | interested | fascinated curious bored |
SURPRISE | surprised | astounded startled |
UNDERSTANDING | comprehending | uncomprehending bewildered/puzzled |
Table 2 provides the semantics for each label in the GENERAL ADJECTIVAL and SPECIFIC ADJECTIVAL columns above.
Table 2 – Basic Cognitive State Semantics Set
ID | Cognitive State | Meaning |
1 | aroused/excited/energetic | cognitive state of alertness and energy |
2 | astounded | high degree of surprised |
3 | attentive | cognitive state of paying attention |
4 | bewildered/puzzled | high degree of incomprehension |
5 | bored | not interested |
6 | cheerful | energetic combined with and communicating happiness |
7 | comprehending | cognitive state of successful application of mental models to a situation |
8 | credulous | cognitive state of conformance to mental models of a situation |
9 | curious | interest due to drive to know or understand |
10 | distracted/absent-minded | not attentive to present situation due to competing thoughts |
11 | expectant/anticipating | attentive to (expecting) future event or events |
12 | fascinated | high degree of interest |
13 | interested | cognitive state of attentiveness due to salience or appeal to emotions or drives |
14 | lethargic | not aroused |
15 | playful | energetic and communicating willingness to play |
16 | sceptical | not credulous |
17 | sleepy | not aroused due to need for sleep |
18 | surprised | cognitive state due to violation of expectation |
19 | startled | surprised by a sudden event or perception |
20 | surprised | cognitive state due to violation of expectation |
21 | thoughtful | attentive to thoughts |
22 | uncomprehending | not comprehending |
These sets have been compiled in the interests of basic cooperation and coordination among AIM submitters and vendors complemented by a procedure whereby AIM submitters may propose extended or alternate sets for their purposes.
An Implementer wishing to extend or replace a Label Set Table for one of the three Factors is requested to do the following:
- Create a new Label Set Table where:
- Proposed additions are clearly marked (in case of extension).
- b. All the elements of the target Cognitive State and levels (up to 3) are listed (in case of replacement).
- Create a new Label Semantics Table where the semantics of elements of the Cognitive State is:
- Added to the semantics of the existing Cognitive State (in case of extension).
- Provided (in case of replacement).
The submitted semantics should have a level of detail comparable to the semantics given in the current Label Semantics Table.
- Submit both tables to the MPAI Secretariat.
The appropriate MPAI Development Committee will examine the proposed extension or replacement. Only the adequacy of the proposed new tables in terms of clarity and completeness will be considered. In case the new tables are not clear or complete, a revision of the tables will be requested.
The accepted Cognitive State Set will be identified as proposed by the submitter and reviewed by the appropriate MPAI Committee and posted to the MPAI web site.
The versioning system is based on a name – MPAI for MPAI-generated versions or “organisation name” for the proposing organisation – with a suffix m.n where m indicates the version and n indicated the subversion.
