2 Overall objectives

Human beings are apparently able to communicate knowledge. However, it is impossible for us to know if we share the same representation of knowledge.

mOeX addresses the evolution of knowledge representations in individuals and populations. The ambition of the mOeX project is to answer, in particular, the following questions:

  • How do agent populations adapt their knowledge representation to their environment and to other populations?
  • How must this knowledge evolve when the environment changes and new populations are encountered?
  • How can agents preserve knowledge diversity and is this diversity beneficial?

We study them chiefly in a well-controlled computer science context.

For that purpose, we combine knowledge representation and cultural evolution methods. The former provides formal models of knowledge; the latter provides a well-defined framework for studying situated evolution.

We consider knowledge as a culture and study the global properties of local adaptation operators applied by populations of agents by jointly:

  • experimentally testing the properties of adaptation operators in various situations using experimental cultural evolution, and
  • theoretically determining such properties by modelling how operators shape knowledge representation.

We aim at acquiring a precise understanding of knowledge evolution through the consideration of a wide range of situations, representations and adaptation operators.

In addition, we still investigate rdf data interlinking with link keys, a way to link entities from different data sets.

3 Research program

3.1 Knowledge and belief representation semantics

We work with knowledge and beliefs represented in computers. In principle, the difference between them is based on their epistemological status: knowledge is true belief. But they can both be expressed in the same knowledge representation languages (like description logics, conceptual graphs and object-based languages). Their semantics is usually defined within model theory initially developed for logics.

We consider a language L as a set of syntactically defined expressions (often inductively defined by applying constructors over other expressions). A representation (o⊆L) is a set of such expressions. It may also be called an ontology. An interpretation function (I) is inductively defined over the structure of the language to a structure called the domain of interpretation (D). This expresses the construction of the “meaning” of an expression in function of its components. A formula is satisfied by an interpretation if it fulfills a condition (in general being interpreted over a particular subset of the domain). A model of a set of expressions is an interpretation satisfying all the expressions. A set of expressions is said consistent if it has at least one model, inconsistent otherwise. An expression (δ) is then a consequence of a set of expressions (o) if it is satisfied by all of their models (noted o⊧δ).

The languages dedicated to the semantic web (rdf and owl) follow that approach. rdf is a knowledge representation language dedicated to the description of resources; owl is designed for expressing ontologies: it describes concepts and relations that can be used within rdf.

A computer must determine if a particular expression (taken as a query, for instance) is the consequence of a set of axioms (a knowledge base). For that purpose, it uses programs, called provers, that can be based on the processing of a set of inference rules, on the construction of models or on procedural programming. These programs are able to deduce theorems (noted o⊢δ). They are said to be sound if they only find theorems which are indeed consequences and to be complete if they find all the consequences as theorems.

3.2 Data interlinking with link keys

Vast amounts of rdf data are made available on the web by various institutions providing overlapping information. To be fully exploited, different representations of the same object across various data sets, often using different ontologies, have to be identified. When different vocabularies are used for describing data, it is necessary to identify the concepts they define. This task is called ontology matching and its result is an alignment A, i.e. a set of correspondences 〈e,r,e'〉 relating entities e and e' of two different ontologies by a particular relation r (which may be equivalence, subsumption, disjointness, etc.) 4.

At the data level, data interlinking is the process of generating links identifying the same resource described in two data sets. Parallel to ontology matching, from two datasets (d and d') it generates a link set made of pairs of resource identifier.

We have introduced link keys 4, 1, 11 which extend database keys in a way which is more adapted to rdf and deals with two data sets instead of a single relation. An example of a link key expression is:

{ 〈 𝖺𝗎𝗍𝖾𝗎𝗋 , 𝖼𝗋𝖾𝖺𝗍𝗈𝗋 〉 } { 〈 𝗍𝗂𝗍𝗋𝖾 , 𝗍𝗂𝗍𝗅𝖾 〉 } l i n k k e y 〈 𝖫𝗂𝗏𝗋𝖾 , 𝖡𝗈𝗈𝗄 〉

stating that whenever an instance of the class 𝖫𝗂𝗏𝗋𝖾 has the same values for the property 𝖺𝗎𝗍𝖾𝗎𝗋 as an instance of class 𝖡𝗈𝗈𝗄 has for the property 𝖼𝗋𝖾𝖺𝗍𝗈𝗋 and they share at least one value for their property 𝗍𝗂𝗍𝗋𝖾 and 𝗍𝗂𝗍𝗅𝖾, then they denote the same entity. More precisely, a link key is a structure 〈Keq,Kin,C〉 such that:

  • Keq and Kin are sets of pairs of property expressions;
  • C is a pair of class expressions (or a correspondence).

Such a link key holds if and only if for any pair of resources belonging to the classes in correspondence such that the values of their property in Keq are pairwise equal and the values of those in Kin pairwise intersect, the resources are the same. Link keys can then be used for finding equal individuals across two data sets and generating the corresponding 𝗈𝗐𝗅:𝗌𝖺𝗆𝖾𝖠𝗌 links. Link keys take into account the non functionality of rdf data and have to deal with non literal values. In particular, they may use arbitrary properties and class expressions. This renders their discovery and use difficult.

3.3 Experimental cultural knowledge evolution

Cultural evolution applies a generalised version of the theory of evolution to culture. It considers how culture spreads and evolves within human societies 17. In computer science, cultural evolution experiments are performed through multi-agent simulation: a society of agents adapts its culture through a precisely defined protocol: agents perform repeatedly and randomly a specific task, called game, and their evolution is monitored. This aims at discovering experimentally the states that agents reach and the properties of these states.

Experimental cultural evolution has been successfully and convincingly applied to the evolution of natural languages 18. Agents play language games and adjust their vocabulary and grammar as soon as they are not able to communicate properly, i.e. they misuse a term or they do not behave in the expected way. It showed its capacity to model various such games in a systematic framework and to provide convincing explanations of linguistic phenomena.

We adapt this experimental strategy to knowledge representation 2. Agents use their, shared or private, knowledge to play games and, in case of failure, they use adaptation operators to modify this knowledge. We monitor the evolution of agent knowledge with respect to their ability to perform the game (success rate) and with respect to the properties satisfied by the resulting knowledge itself. Such properties may, for instance, be:

  • Agents converge to a common knowledge representation (a convergence property).
  • Agents converge towards different but compatible (logically consistent) knowledge (a logical epistemic property), or towards closer knowledge (a metric epistemic property).
  • That under the threat of a changing environment, agents that have operators that preserve diverse knowledge recover faster from the changes than those that have operators that converge towards a single representation (a differential property under environment change).

Our goal is to determine which operators are suitable for achieving desired properties in the context of a particular game.

4 Application domains

Our work on data interlinking aims at application to linked data offered in RDF on the web. It has found applications in thesaurus and bibliographical data interlinking.

mOeX's work on cultural knowledge evolution is not directly applied and rather aims at isolating general principles of knowledge evolution. However, we foresee its potential impact in the long term in fields such as smart cities, the internet of things or social robotics in which the knowledge acquired by autonomous agents will have to be shared and adapted to changing situations.

5 Highlights of the year

The highlights of the year are undoubtly Yasser Bourahla's Phd thesis “Multi-agent simulation of cultural ontology evolution through interaction” 10, and Jérôme David's habilitation “Measures for knowledge – with applications to ontology matching and data interlinking” 11.

6 New software, platforms, open data

6.1 New software

6.1.1 Lazylav

  • Name:
    Lazy lavender
  • Keywords:
    Reproducibility, Multi-agent, Simulation
  • Scientific Description:
    Lazy lavender aims at supporting mOeX's research on simulating knowledge evolution. It is not a general purpose simulator. However, it features some methodological innovations in term of facilitating publication, recording, and replaying of experiments.
  • Functional Description:

6.1.2 Alignment API

  • Keywords:
    Ontologies, Alignment, Ontology engineering, Knowledge representation
  • Scientific Description:

    The API itself is a Java description of tools for accessing the common format. It defines five main interfaces (OntologyNetwork, Alignment, Cell, Relation and Evaluator).

    We provide an implementation for this API which can be used for producing transformations, rules or bridge axioms independently from the algorithm that produced the alignment. The proposed implementation features: - a base implementation of the interfaces with all useful facilities, - a library of sample matchers, - a library of renderers (XSLT, RDF, SKOS, SWRL, OWL, C-OWL, SPARQL), - a library of evaluators (various generalisation of precision/recall, precision/recall graphs), - a flexible test generation framework that allows for generating evaluation data sets, - a library of wrappers for several ontology APIs , - a parser for the format.

    The API implementation provides an extended language for expressive alignments (EDOAL). EDOAL supports many types of restrictions inspired from description logics as well as link keys. It is fully supported for parsing and serialising in XML. It also provide other serialisers, to OWL and SPARQL queries in particular.

    To instanciate the API , it is sufficient to refine the base implementation by implementing the align() method. Doing so, the new implementation will benefit from all the services already implemented in the base implementation.

  • Functional Description:
    Using ontologies is the privileged way to achieve interoperability among heterogeneous systems within the Semantic web. However, as the ontologies underlying two systems are not necessarily compatible, they may in turn need to be reconciled. Ontology reconciliation requires most of the time to find the correspondences between entities (e.g. classes, objects, properties) occurring in the ontologies. We call a set of such correspondences an alignment.
  • Release Contributions:

    See release notes.

    This is the last release made from gforge svn repository. After it, the Alignment API is hosted by gitlab and versioned with git. It may well be the last formal release, clone from the repo instead.

    The Alignment API compiles in Java 11 (jars are still compiled in Java 8).

7 New results

7.1 Cultural knowledge evolution

In 2023, the work on cultural knowledge evolution has progressed in several directions, tasks, values, motivations, all based on the protocol described in the PhD dissertation of Yasser Bourahla 10.

Concerning link keys the work on extracting link keys led to the PhD dissertation of Nacira Abbas and part of the habilitation of her supervisor Jérôme David 11.

7.1.1 Measuring knowledge diversity

Participants: Adrien Bonnardel, Yasser Bourahla, Jérôme David, Jérôme Euzenat [Correspondent].

Assessing knowledge diversity is useful in our experiments. We had proposed to use an entropy-based diversity measure inspired from 16 and using an ontology distance measure. However, in such measures the maximal diversity is not obtained with a uniform distribution and it has to be computed. This year, we implemented its computation and developed a normalised version of this measure. It should help reconsidering the results previously obtained on knowledge diversity 10 with this new method.

7.1.2 Pluripotent agents

Participants: Jérôme Euzenat, Andrea Kalaitzakis [Correspondent].

Following last years' results, we continued investigating resource-limited agents tackling multiple tasks. We found, by varying the number of tasks assigned to each agent and the number of common properties across these tasks, that agents transfer knowledge from one task to another 7. In addition, we showed that agents with limited memory will specialize on a subset of tasks, whose number depends on available memory. However, it seems that maximising task accuracy and achieving consensus are mutually exclusive 8.

When imposing an equidistribution of the tasks that agents play, global benefits have been identified. First, the agents achieve comparable precision in all tasks. Second, the total wealth acquired by agents is higher and more equitably distributed, but lower than with unlimited agents. The wealth is the accumulation of points acquired when agents make the correct decision. The question is then how could agents adopt this behaviour without imposing it. We attempted to reach this goal by replacing agents from one generation to the other favouring those disagreeing more often (lower success rate), assuming that they have rare knowledge. However, this only has a temporary effect.

This work is part of the PhD thesis of Andreas Kalaitzakis.

7.1.3 Value-sensitive cultural evolution

Participants: Jérôme Euzenat [Correspondent], Adriana Luntraru.

Cultural values are cognitive representations of general objectives, such as independence or mastery, that people use to distinguish whether something is “good” or “bad”. More specifically, people may use their values to evaluate alternatives and pick the most compatible one. We consider values as grounding agent behaviour in cultural knowledge evolution, and more specifically in the way they evolve their ontologies. We used the cultural values of independence, novelty, authority and mastery to influence the choice of which agent adapts in a population of agents sharing the same values. From a weighted aggregation of how much agents adhere to these values, they determine which one adapts its knowledge when two agents disagree, e.g. novelty will give more change to rare knowledge, though mastery will promote knowledge that has proved efficient. Results 14 show that agents do not improve the accuracy of their knowledge without using the mastery value (akin the success biais in social learning 10). Under certain conditions, independence causes the agents to converge to successful interactions faster, and novelty increases knowledge diversity, but both effects come with a large reduction in accuracy. We did not find any significant effects of authority.

This was the master work of Adriana Luntraru.

7.1.4 Intrinsic motivation, curiosity and creativity

Participants: Jérôme Euzenat [Correspondent], Anaïs Siebers.

In cultural knowledge evolution simulations, agent knowledge might be confined to specific areas because the tasks that they perform do not require them to explore more. We considered how agents may be provided with the intrinsic motivation to explore and how this affects their knowledge. Three different kinds of motivation were investigated: curiosity (the will to explore the unknown), creativity (the will to act differently) and non-exploration (the will to not explore new things). Moreover, intrinsic motivation was modelled directly or learned through reinforcement learning. Finally, agents either explored on their own or picked specific interaction partner(s). We have shown that such settings may have a significant effect on the agent knowledge 15. Contrary to the expectations and other studies, this did not lead to an increase in knowledge completeness. Out of all intrinsic motivations, curiosity had the highest accuracy and completeness. Models with reinforcement learning performed similarly as direct models. As expected, intrinsic motivation led to faster convergence of the agents’ knowledge, especially with social agents. Heterogeneously motivated agents only had a higher accuracy and completeness than homogeneously motivated agents in specific cases.

This was the master work of Anaïs Siebers.

7.1.5 Awareness and forgetting in dynamic epistemic logic

Participants: Manuel Atencia, Jérôme Euzenat [Correspondent], Line van den Berg.

Agents use their own vocabularies to reason and talk about the world. Public signature awareness is satisfied if agents are aware of the vocabularies, or signatures, used by all agents. Logics and in particular Dynamic Epistemic Logic rely on public signature awareness. However, this assumption is not desirable for dynamic and open multi-agent systems because it prevents agents to use vocabulary other agents are unaware of and to extend it when encountering new information. We propose a new semantics for awareness that enables us to drop public signature awareness 6. This semantics is based on partial valuation functions and weakly reflexive relations. We added dynamic modalities for raising public and private awareness in which a distinction is made between becoming aware of a proposition and learning its truth value. As a result, the semantics introduced can be used to model agent interaction without the public signature awareness assumption.

This work is part of the PhD thesis of Line van den Berg defended in October 2021.

7.1.6 A social science and the humanities approach to cultural knowledge evolution

Participants: Helga Lendrin [Correspondent], Jérôme Euzenat.

We defined a protocol to experiment with human learners various modalities of knowledge transmission based on the Class? game that we designed. In particular, we want to test the effect of the medium on knowledge acquisition and evolution. This protocol involves groups of pupils learning how to play the game and transmitting it to the next group. Transmission modalities varied in terms of face-to-face physical presence, online or written transmission. A series of tests have been designed in order to determine which playing strategies are acquired by pupils after transmission and after playing.

7.2 Link keys

The investigation of link keys has been pursued following the properties of link key extraction (§3.2).

7.2.1 Link key redundancy

Participants: Jérôme David [Correspondent].

We have continued studying how Formal Concept Analysis and its extensions are well adapted to support the discovery of link keys. Different link key candidates can generate sets of identity links between individuals that can be considered as equal when they are regarded as partitions of the identity relation and thus involving a kind of redundancy. We have studied such a redundancy through partition pattern structures 5. In particular, experiments showed that redundancy of link key candidates while not significant when based on identity of partitions appears to be much more significant when based on similarity.

This work is part of the PhD thesis of Nacira Abbas, co-supervised by Jérôme David and Amedeo Napoli (LORIA).
