text: 'Many applications require explainable node classification in knowledge graphs.
Towards this end, a popular ``white-box'''' approach is class expression learning:
Given sets of positive and negative nodes, class expressions in description logics
are learned that separate positive from negative nodes. Most existing approaches
are search-based approaches generating many candidate class expressions and selecting
the best one. However, they often take a long time to find suitable class expressions.
In this paper, we cast class expression learning as a translation problem and
propose a new family of class expression learning approaches which we dub neural
class expression synthesizers. Training examples are ``translated'''' into class
expressions in a fashion akin to machine translation. Consequently, our synthesizers
are not subject to the runtime limitations of search-based approaches. We study
three instances of this novel family of approaches based on LSTMs, GRUs, and set
transformers, respectively. An evaluation of our approach on four benchmark datasets
suggests that it can effectively synthesize high-quality class expressions with
respect to the input examples in approximately one second on average. Moreover,
a comparison to state-of-the-art approaches suggests that we achieve better F-measures
on large datasets. For reproducibility purposes, we provide our implementation
as well as pretrained models in our public GitHub repository at https://github.com/dice-group/NeuralClassExpressionSynthesis'

text: "Knowledge bases are widely used for information management on the web,\r\nenabling
high-impact applications such as web search, question answering, and\r\nnatural
language processing. They also serve as the backbone for automatic\r\ndecision
systems, e.g. for medical diagnostics and credit scoring. As\r\nstakeholders affected
by these decisions would like to understand their\r\nsituation and verify fair
decisions, a number of explanation approaches have\r\nbeen proposed using concepts
in description logics. However, the learned\r\nconcepts can become long and difficult
to fathom for non-experts, even when\r\nverbalized. Moreover, long concepts do
not immediately provide a clear path of\r\naction to change one's situation. Counterfactuals
answering the question \"How\r\nmust feature values be changed to obtain a different
classification?\" have been\r\nproposed as short, human-friendly explanations
for tabular data. In this paper,\r\nwe transfer the notion of counterfactuals
to description logics and propose the\r\nfirst algorithm for generating counterfactual
explanations in the description\r\nlogic $\\mathcal{ELH}$. Counterfactual candidates
are generated from concepts\r\nand the candidates with fewest feature changes
are selected as counterfactuals.\r\nIn case of multiple counterfactuals, we rank
them according to the likeliness\r\nof their feature combinations. For evaluation,
we conduct a user survey to\r\ninvestigate which of the generated counterfactual
candidates are preferred for\r\nexplanation by participants. In a second study,
we explore possible use cases\r\nfor counterfactual explanations."

text: Class expression learning in description logics has long been regarded as
an iterative search problem in an infinite conceptual space. Each iteration of
the search process invokes a reasoner and a heuristic function. The reasoner finds
the instances of the current expression, and the heuristic function computes the
information gain and decides on the next step to be taken. As the size of the
background knowledge base grows, search-based approaches for class expression
learning become prohibitively slow. Current neural class expression synthesis
(NCES) approaches investigate the use of neural networks for class expression
learning in the attributive language with complement (ALC). While they show significant
improvements over search-based approaches in runtime and quality of the computed
solutions, they rely on the availability of pretrained embeddings for the input
knowledge base. Moreover, they are not applicable to ontologies in more expressive
description logics. In this paper, we propose a novel NCES approach which extends
the state of the art to the description logic ALCHIQ(D). Our extension, dubbed
NCES2, comes with an improved training data generator and does not require pretrained
embeddings for the input knowledge base as both the embedding model and the class
expression synthesizer are trained jointly. Empirical results on benchmark datasets
suggest that our approach inherits the scalability capability of current NCES
instances with the additional advantage that it supports more complex learning
problems. NCES2 achieves the highest performance overall when compared to search-based
approaches and to its predecessor NCES. We provide our source code, datasets,
and pretrained models at https://github.com/dice-group/NCES2.

text: "Classifying nodes in knowledge graphs is an important task, e.g., predicting\r\nmissing
types of entities, predicting which molecules cause cancer, or\r\npredicting which
drugs are promising treatment candidates. While black-box\r\nmodels often achieve
high predictive performance, they are only post-hoc and\r\nlocally explainable
and do not allow the learned model to be easily enriched\r\nwith domain knowledge.
Towards this end, learning description logic concepts\r\nfrom positive and negative
examples has been proposed. However, learning such\r\nconcepts often takes a long
time and state-of-the-art approaches provide\r\nlimited support for literal data
values, although they are crucial for many\r\napplications. In this paper, we
propose EvoLearner - an evolutionary approach\r\nto learn ALCQ(D), which is the
attributive language with complement (ALC)\r\npaired with qualified cardinality
restrictions (Q) and data properties (D). We\r\ncontribute a novel initialization
method for the initial population: starting\r\nfrom positive examples (nodes in
the knowledge graph), we perform biased random\r\nwalks and translate them to
description logic concepts. Moreover, we improve\r\nsupport for data properties
by maximizing information gain when deciding where\r\nto split the data. We show
that our approach significantly outperforms the\r\nstate of the art on the benchmarking
framework SML-Bench for structured machine\r\nlearning. Our ablation study confirms
that this is due to our novel\r\ninitialization method and support for data properties."

text: 'Smart home systems contain plenty of features that enhance wellbeing in everyday
life through artificial intelligence (AI). However, many users feel insecure because
they do not understand the AI’s functionality and do not feel they are in control
of it. Combining technical, psychological and philosophical views on AI, we rethink
smart homes as interactive systems where users can partake in an intelligent agent’s
learning. Parallel to the goals of explainable AI (XAI), we explored the possibility
of user involvement in supervised learning of the smart home to have a first approach
to improve acceptance, support subjective understanding and increase perceived
control. In this work, we conducted two studies: In an online pre-study, we asked
participants about their attitude towards teaching AI via a questionnaire. In
the main study, we performed a Wizard of Oz laboratory experiment with human participants,
where participants spent time in a prototypical smart home and taught activity
recognition to the intelligent agent through supervised learning based on the
user’s behaviour. We found that involvement in the AI’s learning phase enhanced
the users’ feeling of control, perceived understanding and perceived usefulness
of AI in general. The participants reported positive attitudes towards training
a smart home AI and found the process understandable and controllable. We suggest
that involving the user in the learning phase could lead to better personalisation
and increased understanding and control by users of intelligent agents for smart
home automation.'

text: At least 5% of questions submitted to search engines ask about cause-effect
relationships in some way. To support the development of tailored approaches that
can answer such questions, we construct Webis-CausalQA-22, a benchmark corpus
of 1.1 million causal questions with answers. We distinguish different types of
causal questions using a novel typology derived from a data-driven, manual analysis
of questions from ten large question answering (QA) datasets. Using high-precision
lexical rules, we extract causal questions of each type from these datasets to
create our corpus. As an initial baseline, the state-of-the-art QA model UnifiedQA
achieves a ROUGE-L F1 score of 0.48 on our new benchmark.

text: Manufacturing companies are challenged to make the increasingly complex work
processes equally manageable for all employees to prevent an impending loss of
competence. In this contribution, an intelligent assistance system is proposed
enabling employees to help themselves in the workplace and provide them with competence-related
support. This results in increasing the short- and long-term efficiency of problem
solving in companies.

abstract:

text: "Knowledge graph embedding research has mainly focused on the two smallest\r\nnormed
division algebras, $\\mathbb{R}$ and $\\mathbb{C}$. Recent results suggest\r\nthat
trilinear products of quaternion-valued embeddings can be a more effective\r\nmeans
to tackle link prediction. In addition, models based on convolutions on\r\nreal-valued
embeddings often yield state-of-the-art results for link\r\nprediction. In this
paper, we investigate a composition of convolution\r\noperations with hypercomplex
multiplications. We propose the four approaches\r\nQMult, OMult, ConvQ and ConvO
to tackle the link prediction problem. QMult and\r\nOMult can be considered as
quaternion and octonion extensions of previous\r\nstate-of-the-art approaches,
including DistMult and ComplEx. ConvQ and ConvO\r\nbuild upon QMult and OMult
by including convolution operations in a way\r\ninspired by the residual learning
framework. We evaluated our approaches on\r\nseven link prediction datasets including
WN18RR, FB15K-237 and YAGO3-10.\r\nExperimental results suggest that the benefits
of learning hypercomplex-valued\r\nvector representations become more apparent
as the size and complexity of the\r\nknowledge graph grows. ConvO outperforms
state-of-the-art approaches on\r\nFB15K-237 in MRR, Hit@1 and Hit@3, while QMult,
OMult, ConvQ and ConvO\r\noutperform state-of-the-approaches on YAGO3-10 in all
metrics. Results also\r\nsuggest that link prediction performances can be further
improved via\r\nprediction averaging. To foster reproducible research, we provide
an\r\nopen-source implementation of approaches, including training and evaluation\r\nscripts
as well as pretrained models."

text: Many websites offer links to social media sites for convenient content sharing.
Unfortunately, those sharing capabilities are quite restricted and it is seldom
possible to share content with other services, like those provided by a user's
favorite applications or smart devices. In this paper, we present Semantic Data
Mediator (SDM) --- a flexible middleware linking a vast number of services to
millions of websites. Based on reusable repositories of service descriptions defined
by the crowd, users can easily fill a personal registry with their favorite services,
which can then be linked to websites by SDM. For this, SDM leverages semantic
data, which is already available on millions of websites due to search engine
optimization. Further support for our approach from website or service developers
is not required. To enable the use of a broad range of services, data conversion
services are automatically composed by SDM to transform data according to the
needs of the different services. In addition to linking web services, various
service adapters allow services of applications and smart devices to be linked
as well. We have fully implemented our approach and present a real-world case
study demonstrating its feasibility and usefulness.

text: Websites increasingly embed semantic data for search engine optimization.
The most common ontology for semantic data, schema.org, is supported by all major
search engines and describes over 500 data types, including calendar events, recipes,
products, and TV shows. As of today, users wishing to pass this data to their
favorite applications, e.g., their calendars, cookbooks, price comparison applications
or even smart devices such as TV receivers, rely on cumbersome and error-prone
workarounds such as reentering the data or a series of copy and paste operations.
In this paper, we present Semantic Data Mediator (SDM), an approach that allows
the easy transfer of semantic data to a multitude of services, ranging from web
services to applications installed on different devices. SDM extracts semantic
data from the currently displayed web page on the client-side, offers suitable
services to the user, and by the press of a button, forwards this data to the
desired service while doing all the necessary data conversion and service interface
adaptation in between. To realize this, we built a reusable repository of service
descriptions, data converters, and service adapters, which can be extended by
the crowd. Our approach for linking services to websites relies solely on semantic
data and does not require any additional support by either website or service
developers. We have fully implemented our approach and present a real-world case
study demonstrating its feasibility and usefulness.

vandalism detection as an online learning problem, requiring\r\nparticipant software
to predict vandalism in near real-time. The\r\nbest-performing approach achieves
a ROC-AUC of 0.947 at a PR-AUC of 0.458. In\r\nparticular, this task was organized
as a software submission task: to maximize\r\nreproducibility as well as to foster
future research and development on this\r\ntask, the participants were asked to
submit their working software to the TIRA\r\nexperimentation platform along with
the source code for open source release."

text: "The WSDM Cup 2017 was a data mining challenge held in conjunction with the\r\n10th
International Conference on Web Search and Data Mining (WSDM). It\r\naddressed
key challenges of knowledge bases today: quality assurance and entity\r\nsearch.
For quality assurance, we tackle the task of vandalism detection, based\r\non
a dataset of more than 82 million user-contributed revisions of the Wikidata\r\nknowledge
base, all of which annotated with regard to whether or not they are\r\nvandalism.
For entity search, we tackle the task of triple scoring, using a\r\ndataset that
comprises relevance scores for triples from type-like relations\r\nincluding occupation
and country of citizenship, based on about 10,000 human\r\nrelevance judgements.
For reproducibility sake, participants were asked to\r\nsubmit their software
on TIRA, a cloud-based evaluation platform, and they were\r\nincentivized to share
their approaches open source."

text: Wikidata is the new, large-scale knowledge base of the Wikimedia Foundation.
Its knowledge is increasingly used within Wikipedia itself and various other kinds
of information systems, imposing high demands on its integrity.Wikidata can be
edited by anyone and, unfortunately, it frequently gets vandalized, exposing all
information systems using it to the risk of spreading vandalized and falsified
information. In this paper, we present a new machine learning-based approach to
detect vandalism in Wikidata.We propose a set of 47 features that exploit both
content and context information, and we report on 4 classifiers of increasing
effectiveness tailored to this learning task. Our approach is evaluated on the
recently published Wikidata Vandalism Corpus WDVC-2015 and it achieves an area
under curve value of the receiver operating characteristic, ROC-AUC, of 0.991.
It significantly outperforms the state of the art represented by the rule-based
Wikidata Abuse Filter (0.865 ROC-AUC) and a prototypical vandalism detector recently
introduced by Wikimedia within the Objective Revision Evaluation Service (0.859
ROC-AUC).
