PostDoc position in Semantic Wev at IRISA (Rennes, France)

by Sebastien Ferre

Hello, The IRISA lab of University Rennes invites applications for the attached postdoctoral position. *Job title: *postdoc 24 months, starting January 2024 *Project*: MeKaNo (ANR), 2023-2026 *Research Lab*: IRISA, Rennes, France *Team*: LACODAM *Contact*: ferre(a)irisa.fr, peggy.cellier(a)irisa.fr *Keywords*: semantic web, knowledge graphs, query languages, microdata, user interaction *Context and Objectives*: In MeKaNo, we aim to search the web with "Things" (entities), in order to get more accurate results over a wide diversity of sources. Traditional web search engines search the web with strings. However, keyword search often returns many irrelevant documents, pushing users to refine their keyword list following a trial-and-error process. On the other hand, Knowledge Graphs (KG) like Wikidata [1] enable users to search for Things and facts, and to get exact answers. However, there may exist many answers on the web that are not part of the knowledge graph. Moreover, nowadays, many websites include entities and facts in the form of microdata [2], for which there is no query engine so far. In MeKaNo, we aim at combining the querying of knowledge graphs and microdata together in order to reconcile the accuracy of KG querying, and the diversity of web search. To search the web with Things, we face several scientific challenges. Among them, an important one is the definition of a query language that combines knowledge graph querying, web search, and microdata querying. Another challenge is to assist users in the building of such complex queries [3]. We already have an approach (Sparklis [4]) that assists users in knowledge graph querying. The objective of the postdoc is to extend this approach to include web search and microdata querying. *Requirements*: The candidate must hold a Ph.D in Computer Science, preferably in the field of the Semantic Web. Skills in query languages (SPARQL), language design, web programming are a plus. *Application method:* To apply send an email to sebastien.ferre(a)irisa.fr and peggy.cellier(a)irisa.fr with attached a single PDF containing: * Cover letter in which you describe your motivation and qualifications for the position. * Curriculum vitae, including a list of your publications and the contact information of references. *References*: 1.

CfP - Ordinal Methods for Knowledge Representation and Capture (OrMeKR @ K-CAP 2023)

by Tom Hanika

***** 1st CALL FOR PAPERS*****: First international workshop on *Ordinal Methods for Knowledge Representation and Capture (OrMeKR)* in conjunction with *The Twelfth International Conference on Knowledge Capture (K-CAP 2023)* December 5th, 2023, Pensacola, Florida, USA *Submission Deadline: October 15th, 2023* 1.1 Abstract and Scope: ─────────────────────── The concept of order (i.e., partial ordered sets) is predominant for perceiving and organizing our physical and social environment, for inferring meaning and explanation from observation, and for searching and rectifying decisions. Compared to metric methods, however, the number of (purely) ordinal methods for capturing knowledge from data is rather small, although in principle they may allow for more comprehensible explanations. The reason for this could be the limited availability of computing resources in the last century, which would have been required for (purely) ordinal computations. Hence, typically relational and especially ordinal data are first embedded in metric spaces for learning. Therefore, in this workshop we want to collect and discuss ordinal methods for capturing and representing knowledge, their role in inference and explainability, and their possibilities for knowledge visualization and communication. We want to reflect on these topics in a broad sense, i.e., as a tool to arrange, compare and compute ontologies or concept hierarchies, as a feature in learning and capturing knowledge, and as a measure to evaluate model performance. 1.2 Topics of Interest ────────────────────── • Ordinal Aspects for Knowledge Representation and Knowledge Bases • Knowledge Visualization using Order Relations • Ordinal Representation and Analysis of Ontologies • Data Fidelity and Reliability of Ordinal Methods • Theory and Application of Order Dimension and Related Notions • Ordinal Knowledge Spaces and Ordinal Exploration • Scaling and Processing Ordinal Information • Metric Structures in Order Relations • Algorithms for querying Large Ordinal Data • Knowledge Discovery in metric-ordinal Heterogeneous Representation • Ordinal Pattern Structures and Motifs • Methods for Representation Learning of Order Relations • Drawing of Hierarchical Graphs and Knowledge Structures • Non-Linear Ranking in Recommendation Applications • Linear Ordered Knowledge and Learning • Scheduling and Planning • Applications of Ordinal Methods to Scientific Knowledge (e.g., from domains such as Biology, Physics, Social Sciences, Digital Humanities, etc.) • Methodologically Related Fields such as Directed Graphs, Formal Concept Analysis, Conceptual Structures, Relational Data, Recommendation, Lattice Theory, with a Clear Reference to Order Relations and Knowledge 1.3 Important Dates (all dates are AoE) ─────────────────────────────────────── • Submission: October 15, 2023 • Author Notification: October 29, 2023 • Camera Ready: November 12, 2023 1.4 Submission Guidlines and Conditions ─────────────────────────────────────── OrMeKR will focus on contributions to the theory and application of ordinal methods in the realm of knowledge representation and capture. The workshop welcomes *report papers* (summaries of past work concerning ordinal methods), *research papers* (novel results), *position papers* (discussing issues concerning the usefulness of ordinal methods in KR), and *challenge papers* (describing limitations and open research questions). • Submissions should have a minimum of 5 pages and shall not exceed 8 pages. • Submission must use the provided CEUR Template: <https://www.kde.cs.uni-kassel.de/ormekr2023/ceur.zip> • The workshop is not double-blind, hence authors should list their names and affiliations on the submission. • Accepted Papers will be published in CEUR Workshop Proceedings corresponding to K-CAP. • Authors of accepted workshop papers will present their work in plenary sessions during the workshop on December 5th. • Submissions should be emailed to: *[ormekr2023(a)cs.uni-kassel.de]* 1.5 Organizing Committee ──────────────────────── • Tom Hanika ⁃ Institute for Computer Science, University of Hildesheim, Germany ⁃ Berlin School of Library and Information Science, Humboldt-Universität zu Berlin, Germany • Dominik Dürrschnabel ⁃ Knowledge & Data Engineering Group, University of Kassel, Germany • Johannes Hirth ⁃ Knowledge & Data Engineering Group, University of Kassel, Germany 1.6 Program Committee ───────────────────── • Agnès Braud, Université de Strasbourg, France • Diana Christea, Babes-Bolyai University, Romania • Pablo Cordero, University of Malaga, Spain • Bernhard Ganter, TU Dresden, Germany • Rokia Missaoui, University of Quebec in Outaouais, Canada • Robert Jäschke, Humboldt-Universität zu Berlin, Germany • Giacomo Kahn, Université Lumière Lyon 2, France • Léonard Kwuida, Bern University of Applied Sciences, Switzerland • Sebastian Rudolph, TU Dresden, Germany • Gerd Stumme, University of Kassel, Germany • Francisco J.

[OM-2023] 2nd CFP: 18th workshop on Ontology Matching collocated with ISWC

by Cassia TROJAHN

The 18th International Workshop on ONTOLOGY MATCHING (OM-2023) http://om2023.ontologymatching.org/ November 6th or 7th, 2023, International Semantic Web Conference (ISWC) Workshop Program, Athens, Greece BRIEF DESCRIPTION AND OBJECTIVES Ontology matching is a key interoperability enabler for the Semantic Web, as well as a useful technique in some classical data integration tasks dealing with the semantic heterogeneity problem. It takes ontologies as input and determines as output an alignment, that is, a set of correspondences between the semantically related entities of those ontologies. These correspondences can be used for various tasks, such as ontology merging, data interlinking, query answering or navigation over knowledge graphs. Thus, matching ontologies enables the knowledge and data expressed with the matched ontologies to interoperate. The workshop has three goals: 1. To bring together leaders from academia, industry and user institutions to assess how academic advances are addressing real-world requirements. The workshop will strive to improve academic awareness of industrial and final user needs, and therefore, direct research towards those needs. Simultaneously, the workshop will serve to inform industry and user representatives about existing research efforts that may meet their requirements. The workshop will also investigate how the ontology matching technology is going to evolve, especially with respect to data interlinking, knowledge graph and web table matching tasks. 2. To conduct an extensive and rigorous evaluation of ontology matching and instance matching (link discovery) approaches through the OAEI (Ontology Alignment Evaluation Initiative) 2023 campaign: http://oaei.ontologymatching.org/2023/ 3. To examine similarities and differences from other, old, new and emerging, techniques and usages, such as web table matching or knowledge embeddings. TOPICS of interest include but are not limited to: Business and use cases for matching (e.g., big, open, closed data); Requirements to matching from specific application scenarios; Formal foundations and frameworks for matching; Novel matching methods, including link prediction, ontology-based access; Matching and knowledge graphs; Matching and deep learning; Matching and embeddings; Matching and big data; Matching and linked data; Instance matching, data interlinking and relations between them; Privacy-aware matching; Process model matching; Large-scale and efficient matching techniques; Matcher selection, combination and tuning; User involvement (including both technical and organizational aspects); Explanations in matching; Social and collaborative matching; Uncertainty in matching; Expressive alignments; Reasoning with alignments; Alignment coherence and debugging; Alignment management; Matching for traditional applications (e.g., data science); Matching for emerging applications (e.g., web tables, knowledge graphs). SUBMISSIONS Contributions to the workshop can be made in terms of technical papers and posters/statements of interest addressing different issues of ontology matching as well as participating in the OAEI 2023 campaign. Long technical papers should be of max. 12 pages. Short technical papers should be of max. 6 pages. Posters/statements of interest should not exceed 3 pages.

Hi, the CoNo-Concepts Workshop at ICFCA showed that there is growing interest in using Jupyter (and other) notebooks for FCA and that creating a page that collects these notebooks may be useful. Since many people host their notebooks on Github, the easiest way to create such a webpage is to add topics to the notebooks because Github automatically generates a page for each topic. My suggestion for such a topic is concept-analysis-notebooks If you add that to your notebook on Github, it will be added to the page https://github.com/topics/concept-analysis-notebooks BTW it is possible to directly execute notebooks without locally installing any software. One only needs to figure out the URL corresponding to a notebook (for example using https://mybinder.org/). For example, if your notebook resides at https://github.com/YOURNAME/YourRepository/folder/name.ipynb and the branch is "main" then it can be executed at https://mybinder.org/v2/gh/YOURNAME/YourRepository/main?urlpath=lab/tree/fo… without installing anything and without requiring any logins. If you include such a link in your description and Readme, then users can find it quickly. Best wishes Uta

[RecSys 2023] Fifth Knowledge-aware and Conversational Recommender Systems Workshop (KaRS 2023)

by Vito Walter Anelli

Call for Papers Fifth Knowledge-aware and Conversational Recommender Systems Workshop (KaRS 2023) https://kars-workshop.github.io/2023/ Sep. 18th - Sep. 22rd, 2023, Singapore Submission deadline: August 3rd, 2023, AoE [SCOPE] We are pleased to invite you to contribute to the Fifth Knowledge-aware and Conversational Recommender Systems Workshop held in conjunction with the ACM International Conference on Recommender Systems (RecSys 2023), Singapore, from September the 18th to September the 22nd, 2023. In the last few years, a renewed interest of the research community in conversational recommender systems (CRSs) is emerging. This is probably due to the great diffusion of Digital Assistants (DAs) such as Amazon Alexa, Siri, or Google Assistant that are revolutionizing the way users interact with machines. DAs allow users to execute a wide range of actions through an interaction mostly based on natural language messages. However, although DAs are able to complete tasks such as sending texts, making phone calls, or playing songs, they are still at an early stage in offering recommendation capabilities by using the conversational paradigm. In addition, we have been witnessing the advent of more and more precise and powerful recommendation algorithms and techniques able to effectively assess users' tastes and predict information that would probably be of interest to them. Most of these approaches rely on the collaborative paradigm (often exploiting machine learning techniques) and do not take into account the huge amount of knowledge, both structured and non-structured, describing the domain of interest of the recommendation engine. Although very effective in predicting relevant items, collaborative approaches miss some very interesting features that go beyond the accuracy of results and move in the direction of providing novel and diverse results as well as generating an explanation for the recommended items. Furthermore, this side information becomes crucial when a conversational interaction is implemented, in particular for the preference elicitation, explanation, and critiquing steps. The Fifth Knowledge-aware and Conversational Recommender Systems (KaRS) Workshop focuses on all aspects related to the exploitation of external and explicit knowledge sources to feed and build a recommendation engine, and on the adoption of interactions based on the conversational paradigm. The aim is to go beyond the traditional accuracy goal and to start a new generation of algorithms and approaches with the help of the methodological diversity embodied in fields such as Machine Learning (ML), Deep Learning (DL) – including Large Language Models (LLMs) –, Human-Computer Interaction (HCI), Information Retrieval (IR), Information Systems (IS). Consequently, the focus lies on works improving the user experience and following goals such as user engagement and satisfaction or customer value. The aim of this fifth edition of KaRS is to bring together researchers and practitioners around the topics of designing and evaluating novel approaches for recommender systems in order to: * share research and techniques, including new design technologies and evaluation methodologies; * identify the next key challenges in the area; * identify emerging topics in the field. [TOPICS] This workshop aims at establishing an interdisciplinary community with a focus on the exploitation of (semi-)structured knowledge and conversational approaches for recommender systems and promoting collaboration opportunities between researchers and practitioners. Topics of interest include, but are not limited to: - Knowledge-aware Recommender Systems. - Models and Feature Engineering: - Knowledge-aware data models based on structured knowledge sources (e.g., Linked Open Data, BabelNet, Wikidata, etc.) - Semantics-aware approaches exploiting the analysis of textual sources (e.g., Wikipedia, Social Web, etc.) - Knowledge-aware user modeling - Methodological aspects (evaluation protocols, metrics, and data sets) - Logic-based modeling of a recommendation process - Knowledge Representation and Automated Reasoning for recommendation engines - Deep learning methods to model semantic features - Large language models (LLMs) for Knowledge-aware Recommender Systems - Beyond-Accuracy Recommendation Quality: - Using knowledge bases and knowledge graphs to increase recommendation quality(e.g., in terms of novelty, diversity, serendipity, or explainability) - Explainable Recommender Systems - Knowledge-aware explanations to recommendations (compliant with the General Data Protection Regulation) - Online Studies: - Using knowledge sources for cross-lingual recommendations - Applications of knowledge-aware recommenders (e.g., music or news recommendation, off-mainstream application areas) - User studies (e.g., on the user's perception of knowledge-based recommendations), field studies, in-depth experimental offline evaluations - Conversational Recommender Systems. - Design of a Conversational Agent: - Design and implementation methodologies - Dialogue management (end-to-end, dialog-state-tracker models) - UX design - Dialog protocols design - Large language models (LLMs) for Conversational Recommender Systems - User Modeling and interfaces: - Critiquing and user feedback exploitation - Short- and Long-term user profiling and modeling - Preference elicitation - Natural language-, multi-modal-, and voice-based interfaces - Next-question problem - Methodological and Theoretical aspects: - Evaluation and metrics - Datasets - Theoretical aspects of conversational recommender systems [SUBMISSIONS] Submissions of full research papers must be in English, in PDF format in the CEUR-WS two-column conference format available at: http://ceur-ws.org/Vol-XXX/CEURART.zip or at: https://www.overleaf.com/latex/templates/template-for-submissions-to-ceur-w… if an Overleaf template is preferred. Submission will be peer-reviewed and accepted papers will appear in the CEUR workshop series. Papers may range from theoretical works to system descriptions. We particularly encourage Ph.D. students or Early-Stage Researchers to submit their research. We also welcome contributions from the industry and papers describing ongoing funded projects which may result useful to the Knowledge-aware and Conversational Recommender Systems community. The conference language is English. We invite three kinds of submissions, which address novel issues in Knowledge-aware and Conversational Recommender Systems: * Long Papers should report on substantial contributions of lasting value. The Long papers must have a length of a minimum of 6 and a maximum of 8 pages (plus an unlimited number of pages for references). Each accepted long paper will be included in the CEUR online Workshop proceedings and presented in a plenary session as part of the Workshop program. * Short/Demo Papers typically discuss exciting new work that is not yet mature enough for a long paper. In particular, novel but significant proposals will be considered for acceptance in this category despite not having gone through sufficient experimental validation or lacking a strong theoretical foundation. Applications of recommender systems to novel areas are especially welcome. The Short/Demo papers must have a length of a minimum of 3 and a maximum of 5 pages (plus an unlimited number of pages for references). Each accepted short paper will be included in the CEUR online Workshop proceedings * Position/Discussion Papers describe novel and innovative ideas. Position papers may also comprise an analysis of currently unsolved problems, or review these problems from a new perspective, in order to contribute to a better understanding of these problems in the research community. We expect that such papers will guide future research by highlighting critical assumptions, motivating the difficulty of a certain problem, or explaining why current techniques are not sufficient, possibly corroborated by quantitative and qualitative arguments. The Position/Discussion papers must have a length of a minimum of 2 and a maximum of 3 pages (plus an unlimited number of pages for references). Original Position/Discussion accepted papers will be included in the CEUR online Workshop proceedings. Selected Position/Discussion papers will be invited as oral presentations. The review process is single-blind. Submitted papers will be evaluated according to their originality, technical content, style, clarity, and relevance to the workshop. Short and long paper submissions must be original work and may not be under submission to another venue at the time of review. Accepted papers will appear in the workshop proceedings. Submission will be through Microsoft CMT at: https://cmt3.research.microsoft.com/kars2023 [IMPORTANT DATES] * Paper submissions due: August 3rd, 2023 * Paper acceptance notification: August 27th, 2023 * Camera-ready deadline: September 10th, 2023 * Workshop day: September 18th-22nd, 2023 Deadlines refer to 23:59 (11:59 pm) in the AoE (Anywhere on Earth) time zone.
