2021	Amaral, G., Piscopo, A., Kaffee, L.-a., Rodrigues, O. and Simperl, E., Assessing the Quality of Sources in Wikidata Across Languages: A Hybrid Approach, J. Data and Information Quality, Vol. 13 (4), DOI: 10.1145/3484828, 2021. [Abstract] [BibTeX]	URL
Abstract: Wikidata is one of the most important sources of structured data on the web, built by a worldwide community of volunteers. As a secondary source, its contents must be backed by credible references; this is particularly important, as Wikidata explicitly encourages editors to add claims for which there is no broad consensus, as long as they are corroborated by references. Nevertheless, despite this essential link between content and references, Wikidata's ability to systematically assess and assure the quality of its references remains limited. To this end, we carry out a mixed-methods study to determine the relevance, ease of access, and authoritativeness of Wikidata references, at scale and in different languages, using online crowdsourcing, descriptive statistics, and machine learning. Building on previous work of ours, we run a series of microtasks experiments to evaluate a large corpus of references, sampled from Wikidata triples with labels in several languages. We use a consolidated, curated version of the crowdsourced assessments to train several machine learning models to scale up the analysis to the whole of Wikidata. The findings help us ascertain the quality of references in Wikidata and identify common challenges in defining and capturing the quality of user-generated multilingual structured data on the web. We also discuss ongoing editorial practices, which could encourage the use of higher-quality references in a more immediate way. All data and code used in the study are available on GitHub for feedback and further improvement and deployment by the research community.

Abstract: The notion of forgetting, as considered in the famous paper by Lin and Reiter has been extensively studied in classical logic and more recently, in non-monotonic formalisms like logic programming. In this paper, we convey the idea of forgetting to another major AI formalism, namely Dung-style argumentation frameworks. Our approach is axiomatic-driven and not limited to any specific semantics: we propose semantical and syntactical desiderata encoding different criteria for what forgetting an argument might mean; analyze how these criteria relate to each other; and check whether the criteria can be satisfied in general. The analysis is done for a number of widely used argumentation semantics. Our investigation shows that almost all desiderata are individually satisfiable. However, combinations of semantical and/or syntactical conditions reveal a much more interesting landscape. For instance, we found that the ad hoc approach to forgetting an argument, i.e., by the syntactical removal of the argument and all of its associated attacks, is too restrictive and only compatible with the two weakest semantical desiderata. Amongst the several interesting combinations identified, we showed that one satisfies a notion of minimal change and presented an algorithm that given an AF F and argument x, constructs a suitable AF G satisfying the conditions in the combination.

Abstract: In argumentation theory, some reasoning problems involve the enu- meration of all extensions of an abstract argumentation framework. Abstractly speaking, extensions are simply subsets of a given do- main having some special properties. The result of the enumeration is usually presented as a single text file with elements and sets sepa- rated by designated delimiters. Neither the elements within each set (a single extension), nor the extensions themselves are presented in any pre-defined order. Events such as the International Competition of Computational Models of Argumentation require the compar- ison of a large number of enumerations and thus performing the comparisons very efficiently has become very desirable. This paper presents and compares three different alternative representations of extensions, one of which is novel for the argumentation domain, and provides an empirical evaluation of their effectiveness in the comparison of large enumerations. We found that the newly pro- posed representation can perform the comparisons in a much more memory and time efficient manner than existing solutions.

2019	Hao, Q., Keppens, J. and Rodrigues, O., A Self-Training Ontology-Driven Approach to Topic Classification, The 12th International Conference on Computer Science and Information Technology, 2019. [Abstract] [BibTeX]	PDF
Abstract: Abstract-Latent Dirichlet Allocation (LDA) is a topic classification technique that produces a probabilistic model based on word co-occurrence, for the purpose of text classification. Conventional LDA ignores the fact that words may have multiple meanings and that different words may have the same meaning. This focus on the words rather than their meanings limits the accuracy of the classification. This work introduces an intermediate labelling component to LDA using the concepts in DBpedia’s ontology to help capture some of the possible meanings of the words appearing in the documents. We call this novel technique Ontology-Driven LDA (OLDA). As for LDA, OLDA can be combined with a self-training procedure to reduce the amount of manually classified data required (we refer to the self- training variant as ST-OLDA). We compared the classification performance of ST-OLDA against the performance of two other leading self-training classification methods: ST Term Frequency- Inverse Document Frequency (ST TF-IDF) and ST-LDA. Our experimental results show that the inclusion of the ontology component helps to reduce the training time by nearly half whilst achieving the highest accuracy in the classification of four widely used datasets. In particular, ST-OLDA outperforms ST-LDA’s accuracy of classification by as much as 11%.

Abstract: It is well known that the computation of solutions to decision and enumeration problems in argumentation can be very hard. In this work, we analyse some of the results of the 2017 International Competition on Computational Models of Argumentation. Our analysis shifts the focus from the performance of individual solvers to how well/badly they can collectively tackle different classes of abstract argumentation frameworks. In so doing, we were able to identify the instances that were particularly difficult for all/most solvers and look into their particular structural properties.

Abstract: This paper compares the performance of the forward propagation algorithm proposed in [15] (which is used in the solver EqArgSolver) with two custom-built SAT-based argumentation solvers in the search for preferred extensions of abstract argumentation frameworks. The SAT-based solvers employ standard ways of computing argumentation semantics via the characterisation of the concept of extensions as models of propositional logic theories. As a result, the comparisons offer new insights about the employment and combination of reduction and direct approaches to the computation of argumentation semantics.

Abstract: With the growing number of unstructured articles written in natural-language, automated extraction of knowledge, such as associations between entities, is becoming essential for many applications. In this paper, we develop an automated verb-based algorithm for multiple relation extraction from unstructured data obtained on-line. Named Entity Recognition (NER) techniques were applied to extract biomedical entities and relations were recognized by algorithms with Natural Language Processing (NLP) techniques. Evaluation based on F-measure with a random sample of sentences from biomedical literature results an average precision of 90% and recall of 82%. We also compared the performance of the proposed algorithm with a single-relation extraction algorithm, indicating improvements of this work. In conclusion, the preliminary study indicates that this method for multiple-relation extraction from unstructured literature is effective. With different training dataset, the algorithm can be applied to different domains. The automated method can be applied to detect and predict hidden relationships among varying areas.
