This document discusses handling systematic polysemy in lexical resources by interfacing ontologies. It begins by outlining the systematic polysemy of terms denoting institutions and how this poses challenges for lexical resources. It then explores the philosophical ontology of institutions, analyzing them as stratified entities with agentive, material, and abstract components grounded in social acts. Finally, it proposes revising lexical resources by formalizing an ontology of institutions and principles of inheritance, aligning the lexical resource top-level with a foundational ontology to represent the patterns of systematic polysemy involving institution names.

Natural Language Ambiguity and its Effect on Machine LearningIJMER
"Natural language processing" here refers to the use and ability of systems to process
sentences in a natural language such as English, rather than in a specialized artificial computer
language such as C++. The systems of real interest here are digital computers of the type we think of as
personal computers and mainframes. Of course humans can process natural languages, but for us the
question is whether digital computers can or ever will process natural languages. We have tried to
explore in depth and break down the types of ambiguities persistent throughout the natural languages
and provide an answer to the question “How it affects the machine translation process and thereby
machine learning as whole?” .

Introduction to sociology

Reading Guide #2
The Structural functionalist school
RECAP OF RECENT LECTURE(S)
We introduced the course by suggesting to you that
we would study contemporary micro and macro
sociology
-however, before we start examining modern
sociology, we spent a little time examining the history
of the discipline of sociology.
-we saw that in the 19th century, 3 founding fathers of
sociology emerged, in response to the changes in
society which they saw.
Marx tried to give an explanation of the way society
had developed so as to produce the omnipresent
social phenomenon of ‘industrialization’
S1001Fall2014RG2StructuralFunctionalism 9/9/2014 3:36 PM [Type text]

Durkheim tried to give an explanation of the way
society had evolved so as to produce the widespread
phenomenon of ‘urbanization’
Weber tried to give an explanation of the way society
had developed so as to produce the omnipresent
social phenomenon of ‘bureaucratization’.
However, none of these sociologists (apart from
Weber to some extent) really paid much attention to
the phenomenon of the social individual.
So we will begin our analysis of modern sociology by
looking at how, in the 20th century, sociology started
realizing that it had to start investigating the (social)
individual, and how that individual acts socially.
But first we will look at how the ideas of Durkheim
primarily, got translated into a North American version
for the 20th century
Begins with Talcott Parsons (Harvard scholar) going
to Europe and learning from the European theorists
He brings back these ideas to north America
(especially those of Durkheim and Weber)

And adapts Durkheim’s ‘evolutionary’ model (which
came from biology) to a more ‘medical model’ (still
rooted in biology)
This new model became the ‘structural functionalist
school’
Structural-Functionalism
Focusses on: structure and function of institutions in
society
Biological analogy
Medical doctor analogy
notion of system, everything working together smoothly
needs of the system
interdependence of parts
boundaries within the system
equilibrium

Adaptation
Goal attainment
Integration

As we have seen with the functionalist
perspective, they always want to understand
phenomena in terms of how these phenomena
contribute to the functioning of society, as well
they often examine families for how the
internal parts of the system function together.
So if we look at the family from a societal
perspective, we can understand it .

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

1. (a) The bank was very nice and understanding [individuals]
(b) The bank is right around the corner [building]
(c) The bank merged with the American Security Bank
[abstract institution]
2. (a) He’s on a trip with his school [individuals]

(c) School was founded by Charles the Great [abstract
institution]
3. (a) The church was present at the manifestation [individuals]
(b) We go to church every Sunday [building]
(c) The Orthodox and Catholic church divided in 1054
[abstract institution]
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 4
5. Standard vs. systematic (regular or logical) polysemy
Coordination test
- Standard polysemy
“Ambiguity tests [. . .] utilise the fact that independent senses
of a lexical form are antagonistic to one another ; that is to
say, they cannot be brought into play simultaneously without
oddness. Contexts which do activate more than one sense at a
time give rise to [. . .] zeugma” ([Cruse86] : 61)
- Systematic polysemy
Though the intersection of the entities denoted by each
contextual meaning of the word is empty (physical/individual/
abstract) coordination tests are felicitous

4. The bank went on strike [employees] in view of its upcoming merger

largest Christian church [members]
Vs.
7. ? ? John found the key to the mystery, but it doesn’t fit the lock
8. ? ? The key to success is very heavy
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 6
7. Systematic polysemy in WordNet
WordNet’s structure : quick reminder
- Structured in synsets (classes of synonyms), commonly taken
as equivalent to concepts
- Synsets are in turn organized in hierarchies, defined by
hypernym or IS-A relationships
- At the top level, these hierarchies are organized into base
types, 25 primitive groups for nouns, and 15 for verbs
Representation of polysemy in WordNet
- Polysemy as multiple inheritance or multiple hypernym
relations
- Contrastive (homonymy) and complementary ambiguity
(polysemy) are handled in the same way
IS-A overloading problem
([Gangemi et al. 02, 03] [Guarino07]) multiple hypernymy generates
- logical incoherences
- conceptual confusions
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 7
8. From the lexicon to ontology
Requirements for an adequate account of systematic
polysemy
- Introduction of complex categories of objects ([Pustejovsky95]
[Asher10] “dot-types”) : ’semantic facets’ linked through
non-hierarchical relations
- Definition of orthogonal connections between categories and
mechanisms of inheritance through such orthogonal relations
Working hypothesis
- Institutional as stratified entities (grounded in the material
realm and on intentional agents involved in social interaction)
- The systematic polysemy as semantic upraisal of the complex
ontological structure of denoted entities
→ Understanding the patterns of systematic polysemy involving
names of institutions requires understanding the patterns of
ontological constitution of institutional entities

1 Systematic polysemy and names of institutions : a challenge for
lexical resources
2 A (philosophical) incursion into institutional ontology
3 Handling systematic polysemy by interfacing ontologies and

Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 9
10. Descriptive common sense (social) ontology
A common semantic assumption in NLP
- Lexical semantic as the reflection of common sense
categorization of the world
Metaphysics of the “common sense world”
- Objects surrounding us in our everyday environment and
activities
- E.g. trees, rocks, rivers, but also chairs, tables, houses, banks,
universities, etc.
General ontological assumptions
- Non-relativistic approach : there is an objective core structure
of the common sense world as it is delivered trough different
cultures
- Non-reductionist approach : “ordinary objects” have proper
identity and persistence conditions, viz. do not reduce to the
ontological building blocks studied in foundational ontology
(material, intentional, abstract)
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 10
11. Philosophical background
The phenomenological tradition
- Husserl : study of the “lifeworld” or “personal world” as a
proper ontological layer structured by multiple dependence
relations on “lower” layers
- G¨otingen circle (Ingarden, Reinach) : ontological foundations
of the literary work, positive law, etc.
Recent advances at the joint between phenomenological and
analytic tradition
- Common sense metaphysics, developments and integration in
contemporary analytical debates : B. Smith, A.L. Thomasson
- Development of a formal theory of dependence, taken as the
fundamental ontological relation structuring reality : K. Fine,
J. Lowe, P. Simons
The analytic tradition
- Searle’s social ontology grounded in his theory of intentionality
(with divergences but also overlaps with the phenomenological
approach)
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 11
12. Institutions as “stratified” intentional products
Products of social acts (or collective intentionality) [Reinach,
Searle]
- A social act (e.g. promises, commands, etc.) is such that it
necessarily involves : being produced in the direction of others,
thus being externalized, and being grasped as such by others
→ Collective intentionality
- Social acts are productive, viz. something new comes into
being : very roughly, new connections between agents hence
bound into social-institutional groups
“Stratified” or “many-layered” entities [Ingarden]
- “Organic structures” or “formations” depend upon
“heterogeneous” ontological strata for their existence and
identity (material, ideal, intentional)
- As such, these entities cannot be classified in either of the
major categories of objects accepted by traditional
metaphysics, though they are grounded on them
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 12
13. The (quasi) abstract component of institutions
Deontic powers
- Drawing on the example of promises : paradigmatic pre-legal
social acts
- Social acts produce claims and obligations regulating actions
Institutional roles
- Deontic powers are tied to institutional roles (e.g. president,
employee), viz. place-holders for patterns of actions
- RLs are defined by (i) constitutive norms, determining the
conditions under which an entity can qualify for role ; (ii)
deontic norms, regulating the actions of players of a given role
Abstract artifacts
- Roles and deontic powers are not irreducible to intentional
states nor material entities.
- (i) They are abstract in that they lack spatial location ; (ii)
they are artifactual in being man-created, temporally located
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 13
14. The agentive component of institutions
Constant dependence on agents
- Deontic powers, like claims and obligations, can only exist
insofar as there are people tied by them
- The dependence of such powers on agents consists in the fact
that they cannot endure unless relevant bearers exist
Generic dependence on agents
- Institutional deontic powers do not tie specific individuals :
they can be passed on from a bearer to another (e.g.
replacement of the members of an organization)
- The perdurance of an institution only requires the existence of
some individuals qualifying of the relevant institutional roles,
viz. the existence of some bearer of the relevant deontic powers
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 14
15. The material component of institutions
Material objects invested with institutional status (role)
The institutional status of material objects is derivative upon the
actions of agents within the institution
(i) Institutions determine patterns of actions for the agents
playing different institutional roles
(ii) These patterns (correlatively roles) include actions in relation
to a material object
Two cases :
1. Determining the conditions under which a person is tied to
“temporary institutional roles” may involve relational
conditions to a material entity
A building housing an institutional activity (bank, university).
Determines patterns of actions associated for people while
present in the building.
2. Institutional roles may involve regulated actions bearing on a
material entity
French national territory. The rights and duties of French
citizens regulate ex. there movement on the French territory.

3 Handling systematic polysemy by interfacing ontologies and
lexical resources
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 16
17. Ontology-driven revision of lexical resources
General strategy
- Formalizing the fundamental categories and relations
structuring institutional entities in a top-level ontology
- Formulating principles of orthogonal quality-inheritance, in
particular quality-inheritance through dependence
- Aligning the top level of lexical resource with top-level ontology
Framework : DOLCE foundational ontology [Masolo et al.03]
- Alignment of WordNet’s upper level and DOLCE foundational
ontology has been successfully achieved [Oltramary et al. 2002]
[Gangemi et al. 03]
- A preliminary characterization of social roles [Masolo et al. 04]
and organizations [Bottazi&Ferrario 09] has been proposed in
DOLCE
Aim : Show how orthogonal inheritance involved in institutional
entities can be formally characterized by focussing on the case of
organizations and bringing minimal extensions to existing results.
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 17
18. DOLCE basic categories
- ED(x) :“x is an endurant”, i.e. an entity that is wholly present at
any time it is present
- PD(x) : “x is a perdurant”, i.e. an entity that extends through time,
has temporal parts, and is only partially present at any given time
- APO(x) : “x is an agentive physical object”, i.e. an endurant that
has intentionality
- NAPO(x) : “x is an non-agentive physical object”, i.e. an endurant
that has no intentionality
- SOB(x) : “x is a social object”, i.e. an endurant that (i) is not a
physical object ; (ii) depends on a community of intentional agents
- PC(x, y, t) : the endurant x participates in the perdurant y at time
t, i.e. endurants “involved” in an occurrence, typically an event
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 18
19. Extension to social individuals
Social individuals (SI(x)) (e.g. the bank of France, the Peugeot
company) as social objects which can be described and defined
using a number of social concepts.
[Gangemi&Mika03] : Reifying concepts and descriptions to be able
to predicate on them :
CN(x) : “x is a social concept”
DS(x) : “x is a description”
DF(x, y) : “x is defined by the description y”
US(x, y) : “x is (re)used in the description y”
CF(x, y, t) : “at time t, x is classified by the concept y”
[Bottazi&Ferrario09] : Modifying the argument restrictions for DF
and US so that they can apply to social individuals
(A1) US(x, y) → ((CN(x) ∨ SI(x)) ∧ DS(y))
(A2) DF(x, y) → US(x, y)
(A3) (CN(x) ∨ SI(x) → ∃y (DF(x, y))
(T1) DF(x, y) → ((CN(x) ∨ SI(x)) ∧ DS(y))
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 19
20. Some basic relations
Following [Bottazi&Ferrario09] :
Organizations, like any social object, are created by collective
intentionality, viz. involve a social event (SEV(x))
This event links institutions and their defining descriptions through
social commitment, which “turns the description into a prescription
for agents”. This dimension is captured through the primitive
validity relation (VAL(x, y))
(A4) VAL(x, y) → SI(y) ∧ DF(y, x) ∧ ∃z, t (SEV (z) ∧ PC(x, z, t) ∧ PC(y, z, t)
New concepts and roles are created that have a meaning and a
“legal status” inside the organization. These institutionalized
(INST(x, y)) concepts and roles are introduced through valid
descriptions
(D1) INST(x, y) =df CN(x) ∧ SI(y) ∧ ∃z (VAL(z, y) ∧ US(x, z))
Alexandra Arapinis (Paris 1 - IHPST) PHILOWEB 2010 20
21. Social roles
Based on the notion of social role (RL(x)), we distinguish agentive and
non-agentive roles, depending on the kind of entity classified by a role
(CF(x, y, t) [Masolo et al 04]).
Agentive roles regulate the behavior that agents must observe when
they play definite roles.“x is an agentive role in y” (ARL(x, y)) is
defined by
(D2) ARL(x, y) =df RL(x) ∧ INST(x, y) ∧ ∀z, t (CF(z, x, t) → APO(z))
Non-agentive roles (NARL(x, y)) regulate actions of agents
involving the object invested with the given role. They are
institutionalized insofar as they are ’definitional’ of the agentive
roles.
The requirement relation (RQ(x, y) :“x requires y”) captures this
’definitional’ connection through :
(A5) (RQ(x, y) ∧ DF(x, d)) → US(y, d)
(D3) NARL(x, y) =df RL(x) ∧ ∀z, t (CF(z, x, t) → NAPO(z))∧
∀v (ARL(v, y) → RQ(v, x))

22. Partial characterization of organizations
Relations connecting agents and non-agentive physical objects to social
individuals (drawing on and extending [Bottazi&Ferrario09]) :
“x is affiliated to y at time t”
(A6) AFF(x, y, t) → ∃z ARL(z, y) ∧ CF(x, z, t)
“x counts as y at time t” (following Searle)
(A7) CNT(x, y, t) → ∃z NARL(z, y) ∧ CF(x, z, t)
Necessary conditions for a social individual to be an organization, using
the relation of being present a time t (PRE(x, t))
“x is an organization”
(A8) ORG(x) → ∃t (PRE(x, t) ∧ ∀t (PRE(x, t ) → ∃y AFF(y, x, t ))
“x is a materially grounded organisation”
(D4) MORG(x) =df ORG(x) ∧ ∀t (PRE(x, t) → ∃y CNT(y, x, t))

23. Organizations and dependence
The dependences structuring organizations :
One important axiom of the CF relation :
(A9) CF(x, y, t) → PRE(x, t)
From the definition of Generic Constant Dependence (GD(φ, ψ))
(D5) GD(φ, ψ) =df (∀x(φ(x) → ∃t(PRE(x, t))∧
∀x, t((φ(x) ∧ PRE(x, t)) → ∃y(ψ(y) ∧ PRE(x, t)))
and (A9) the following theorems can be prouved :
(T2) GD(ORG, AFF)
(T3) GD(MORG, AFF)
(T4) GD(MORG, CNT)
[(T) SD(ORG, DS)]

24. Indirect quality-inheritance
Kinds of qualities
- TQ(x) : “x is a temporal quality”
- SQ(x) : “x is a spatial quality ”
- AQ(x) : “x is an abstract quality”
- To which we add AGQ(x) : “x is an agentive quality”
Extending argument restrictions (where qt(x, y) is read “x is a
quality of y” and Kx stands for “the kind of x”)
(A10) qt(x, y) ↔ (TQ(x) → D(Ky , PD))
(A11) qt(x, y) ↔ (SQ(x) → D(Ky , ED))
(A12) qt(x, y) ↔ (AQ(x) → D(Ky , NPED))
(A13) qt(x, y) ↔ (AGQ(x) → D(Ky , APO))

25. Remarks on indirect inheritance
Note that :
(A10- A12) cover the original argument constraints on qualities
from DOLCE :
(i) a PD(resp. ED, NPED, APO) is constantly dependent on
itself,
(ii) a TQ (resp. SQ, AQ, AGQ) is constantly dependent on PD
(resp. ED, NPED, APO)
Indirect inheritance extends beyond the category of social
individuals to all cases of constant dependence
Axioms stipulating that a PD indirectly inherits SQ from its
participants, and that a PED indirectly inherits TQ from the event
it participates to follow as theorems

26. Perspectives
Concerning institutional ontology
- Further exploit philosophical literature in the ontology of
institutional entities and in particular its recent developments
(e.g. legal, geographic)
- Pursue the formal characterization of social individuals and
relations
Concerning the ontology/lexical resource interface
- Extending and testing the hypothesis of a correlation between
systematic polysemy and ontological dependence
- Use systematic polysemy detection in WordNet (viz. multiple
hypernym detection) as a tool to reveal underlying ontological
dependences
- Draw general patterns of dependence and integrate them in
foundational ontologies like DOLCE
