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. We deal with software agents and formal knowledge representation. 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 representation semantics

We work with semantically defined 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 (oL) 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 oδ).

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 oδ). 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.) 5.

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, L made of pairs of resource identifier.

We have introduced link keys 5, 1 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 considers how culture spreads and evolves with human societies 23. It applies a generalised version of the theory of evolution to culture. In computer science, cultural evolution experiments are performed through multi-agent simulation: a society of agents adapts its culture through a precisely defined protocol 20: 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 25, 24. 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. Such experiments have shown how agents can agree on a colour coding system or a grammatical case system.

Work has recently been developed for evolving alignments between ontologies. It can be used to repair alignments better than blind logical repair 4, to create alignments based on entity descriptions 18, to learn alignments from dialogues framed in interaction protocols 19, 22, or to correct alignments until no error remains 214 and to start with no alignment 3. Each study provides new insights and opens perspectives.

We adapt this experimental strategy to knowledge representation 4. 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 (see previous years' report).

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 adapted to changing situations.

5 Highlights of the year

In 2022, ChatGPT was all the rage. We thus tried to challenge it.

Unfortunately, AI is not yet able to produce this activity report. So, this year again, what you will read had to be written by a human being.

6 New software and platforms

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:
    Lazy Lavender is a simulation environment for cultural knowledge evolution, i.e. running randomised experiments with agent adjusting their knowledge while attempting to communicate. It can generate detailed report and data from the experiments and directions to repeat them.
  • Release Contributions:

    Lazy is continuously evolving and do not feature stable releases.

    Instead, use git hashes to determine which version is used in a simulation.

  • News of the Year:
    In 2022, two threads were followed: (a) concerning alignment repair, the addition of disruptive events and specific parameters to control diversity, (b) increased parameters to control the behaviour of specialised agents (number of tasks played, size of ontologies, choice of the other player, task preferences).

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).

6.1.3 LinkEx

  • Keywords:
    LOD - Linked open data, Data interlinking, Formal concept analysis
  • Functional Description:
    LinkEx implements link key candidate extraction with our initial algorithms, formal concept analysis or pattern structures. It can extract link key expressions with inverse and composed properties and generate compound link keys. Extracted link key expressions may be evaluated using various measures, including our discriminability and coverage. It can also evaluate them according to an input link sample. The set of candidates can be rendered within the Alignment API's EDOAL language or in dot.
  • News of the Year:
    We are now able to compute the owl:sameAs closure of a set of links (and also the partition of instances). EDOAL rendering of link keys has been improved: give the pair of classes attached with the link key, render link keys with property composition and inverse.

7 New results

7.1 Cultural knowledge evolution

2022 saw the continuation of our work on experimental cultural knowledge evolution through studying the impact of diversity of knowledge and of agent preference on knowledge. Concerning link keys the work on reasoning in description logic with link keys led to the PhD thesis of Khadija Jradeh; the work on extracting them was pursued in the perspective of increasing the quality of link keys.

7.1.1 Knowledge transmission across agent generations

Participants: Manuel Atencia, Yasser Bourahla [Correspondent], Jérôme Euzenat.

Last year, we showed that vertical transmission improves on horizontal transmission even without drastic selection and oriented learning. We also showed that horizontal transmission is able to compensate for the lack of parent selection if it is maintained for long enough 7, 10, 11. In 2022, we also confirmed that that this setting was able to preserve knowledge diversity, although it decreases.

This work is part of the PhD thesis of Yasser Bourahla.

7.1.2 Measuring and controlling knowledge diversity

Participants: Yasser Bourahla, Jérôme David, Jérôme Euzenat [Correspondent], Meryem Naciri.

Assessing knowledge diversity may be useful for many purposes. In particular, it is necessary to measure diversity in order to understand how it arises or is preserved (see §7.1.1). It is also necessary to control it in order to measure its effects. We have considered measuring knowledge diversity using two components: (a) a diversity measure taking advantage of (b) a knowledge difference measure 8. We have proposed general principles for such components and compared various candidates. The most satisfycing solutions are entropy-based measures. We designed algorithms using these measures to generate populations of agents with controlled levels of knowledge diversity.

7.1.3 Pluripotent agents

Participants: Jérôme Euzenat, Andrea Kalaitzakis [Correspondent].

We introduced multi-tasking agents that interact over a limited set of tasks. Unintuitively, our experiments demonstrate that multi-task agents are not necessarily less accurate than specialised one. We constrained agent memory size to be limited, in order to avoid multi-tasking agents to learn all tasks in the long term. On the one hand, when agents have unlimited memory, generalist agents are always more accurate than specialist agents on all tasks. On the other hand, when agents have limited memory, results suggest that the goals of maximising task specific accuracy and achieving consensus are mutually exclusive. Agents can either specialise in detriment of their interoperability, or learn to agree but fail to specialise.

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

7.1.4 Experiment reproducibility

Participants: Jose Luis Aguirre Cervantes, Yasser Bourahla, Jérôme Euzenat [Correspondent].

We have pursued our effort to document the repurposing of our experiments as Jupyter notebooks (https://sake.re). Some neglected benefits of semantically describing experiments provide more arguments in favour of scientific knowledge graphs 9. Beyond being searchable through flat metadata, a knowledge graph of experiment descriptions may be able to provide answers to scientific and methodological questions. This includes identifying non experimented conditions or retrieving specific techniques used in experiments. In turn, this is useful for researchers as this information can be used for repurposing experiments, checking claimed results or performing meta-analyses.

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

Participants: Helga Lendrin [Correspondent], Jérôme Euzenat.

We are designing experiments with human learners to test the hypothesis that the medium used for knowledge transmission has an effect on its acquisition and evolution. As a corollary, we want to assess the impact of physical presence, as a medium for knowledge transmission, on knowledge evolution. In other words, is the hybrid mode of teaching closer to the written modality of knowledge transmission or to the face-to-face classroom modality? For that purpose, we are investigating the possible use of the Class? game in the classroom.

7.2 Link keys

The link key exploration is continued following two directions (§3.2):

  • Extracting link keys;
  • Reasoning with link keys.

7.2.1 Strategies for identifying high-quality link keys

Participants: Jérôme David [Correspondent].

We have studied and evaluated the redundancy of link keys based on the fact that owl:sameAs is an equivalence relation. To that extent we use the formalism of Partition Pattern Structures (pps) to detect such redundancy 6. In the pps concept lattice, every concept has an extent representing a link key candidate and an intent representing a partition of instances into sets of equivalent instances. Experiments showed two main results. First, redundancy of link keys is not so significant in real-world datasets. Nevertheless, the link key discovery approach based on pps returns a reduced number of non redundant link key candidates.

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

7.2.2 An effective algorithm for reasoning with link keys

Participants: Manuel Atencia, Khadija Jradeh [Correspondent].

Link keys can be thought of as axioms in a description logic. It is thus possible to reason with link keys in combination with ontologies and alignments. In 2022, we have defined a compressed tableau for reasoning in the description logic 𝒜ℒ𝒞 extended with link keys and inverse roles. This provides a solid basis for designing a worst-case optimal algorithm for reasoning in the description logic 𝒜ℒ𝒞ℐ extended with link keys. We have also proposed and evaluated different strategies to integrate reasoning with link keys in the data interlinking pipeline.

This work was the final part the PhD thesis of Khadija Jradeh 14, co-supervised by Chan Le Duc (LIMICS).
