Towards Automated Semantics-Driven Web Service Composition: Case Study on Question Answering Systems
2024 IEEE 18th International Conference on Semantic Computing (ICSC)
Year: 2024 | Conference Paper |
When following the Component-based Architecture (CBA), Web Services (WSs), as individual components, are composed to meet the functional and non-functional requirements of users. As the number of available WSs increases, this process becomes more complex. Therefore, designers must be able to easily (1) define, (2) select, (3) verify, and (4) execute composite WSs. While many papers focus on the ex...Show More
QALD-9-plus: A Multilingual Dataset for Question Answering over DBpedia and Wikidata Translated by Native Speakers
Aleksandr Perevalov;Dennis Diefenbach;Ricardo Usbeck;Andreas Both
2022 IEEE 16th International Conference on Semantic Computing (ICSC)
Year: 2022 | Conference Paper |
Cited by: Papers (13)
The ability to have the same experience for different user groups (i.e., accessibility) is one of the most important characteristics of Web-based systems. The same is true for Knowledge Graph Question Answering (KGQA) systems that provide the access to Semantic Web data via natural language interface. While following our research agenda on the multilingual aspect of accessibility of KGQA systems, ...Show More
Enhancing the Accessibility of Knowledge Graph Question Answering Systems through Multilingualization
2022 IEEE 16th International Conference on Semantic Computing (ICSC)
Year: 2022 | Conference Paper |
Cited by: Papers (2)
There are around 7000 languages spoken today in the world, yet English dominates in many research communities e.g., Knowledge Graph Question Answering (KGQA). The goal of a KGQA system is to provide natural language access to a knowledge graph. While many research works aim to achieve the best possible QA quality over English benchmarks, only a small share of them additionally focus on providing a...Show More
Improving the Question Answering Quality using Answer Candidate Filtering based on Natural-Language Features
Aleksandr Gashkov;Aleksandr Perevalov;Maria Eltsova;Andreas Both
2021 16th International Conference on Intelligent Systems and Knowledge Engineering (ISKE)
Year: 2021 | Conference Paper |
Cited by: Papers (4)
Software with natural-language user interfaces has an ever-increasing importance. However, the quality of the included Question Answering (QA) functionality is still not sufficient regarding the number of questions that are answered correctly.In our work, we address the research problem of how the QA quality of a given system can be improved just by evaluating the natural-language input (i.e., the...Show More
Towards a Message-Driven Vocabulary for Promoting the Interoperability of Question Answering Systems
Kuldeep Singh;Andreas Both;Dennis Diefenbach;Saeedeh Shekarpour
2016 IEEE Tenth International Conference on Semantic Computing (ICSC)
Year: 2016 | Conference Paper |
Cited by: Papers (18)
Question answering (QA) is one of the biggest challenges for making sense out of data. The Web of Data has attracted the attention of the QA community and recently, a number of schema-aware QA systems have been introduced. While research achievements are individually significant, yet, integrating different approaches is not possible due to lack of a systematic approach for conceptually describing ...Show More
Motive-based search: Computing regions from large knowledge bases using geospatial coordinates
Liliya Avdiyenko;Martin Nettling;Christiane Lemke;Matthias Wauer;Axel-Cyrille Ngonga Ngomo;Andreas Both
2015 7th International Joint Conference on Knowledge Discovery, Knowledge Engineering and Knowledge Management (IC3K)
Year: 2015 | Conference Paper |
To create a better search experience for end users and to satisfy their actual intents even for vaguely formulated queries, a contemporary search engine has to go beyond simple keyword-based retrieval concepts. For a geospatial search, where user queries can be quite complex such as “places for winter sport holidays and culture in Central Europe”, we introduce the notion of geospatial motifs denot...Show More
Automatic Component Protocol Generation and Verification of Components
2010 36th EUROMICRO Conference on Software Engineering and Advanced Applications
Year: 2010 | Conference Paper |
Cited by: Papers (1)
In several works a method was suggested to overcome the lack of signature-based composition currently enabled in component-based and service-oriented architectures (SOA). Several approaches allow to encode non-functional properties of a single component in a contract (component protocol) where the remote calls to a component are taken into consideration. Component protocols ensures that bugs or un...Show More
A Step Towards a More Practical Protocol Conformance Checking Algorithm
2009 35th Euromicro Conference on Software Engineering and Advanced Applications
Year: 2009 | Conference Paper |
Cited by: Papers (4)
In previous works we suggested an approach to verify if in a component-based system the interaction behavior to a component obeys the specified requirements.We can capture unbounded recursion, synchronous method calls and call backs as well as asynchronous method calls and unbounded parallel behavior including synchronization.In an industrial environment we have the problem, that extensive use of ...Show More
On More Predictable Implementations of Reliable Workflows in Service-oriented Architectures
2009 Seventh IEEE European Conference on Web Services
Year: 2009 | Conference Paper |
Cited by: Papers (2)
Implementing a workflow using previously implemented services is a typical task while dealing with Service-oriented Architectures (SOA). Defining these workflows is the task of business (process) analysts in tight collaboration with clients or domain experts. Unfortunately these analysts only have a sketchy view on the Service-oriented Architecture, thus they do not know which investigations a spe...Show More
Today model checking of Web Services formulated in BPEL is often reduced by transforming BPEL-processes to Petri nets. These can be model checked using traditional approaches. If recursion is present in the BPEL model this approach hides some possible violations of the wished behaviour. We present an approach which allows the Web Service developer to formulate more properties of the required usage...Show More
