NLSC: Unrestricted Natural Language-based Service Composition through Sentence Embeddings
Current approaches for service composition (assemblies of atomic services)
require developers to use: (a) domain-specific semantics to formalize services
that restrict the vocabulary for their descriptions, and (b) translation
mechanisms for service retrieval to convert unstructured user requests to
strongly-typed semantic representations. In our work, we argue that effort to
developing service descriptions, request translations, and matching mechanisms
could be reduced using unrestricted natural language; allowing both: (1)
end-users to intuitively express their needs using natural language, and (2)
service developers to develop services without relying on syntactic/semantic
description languages. Although there are some natural language-based service
composition approaches, they restrict service retrieval to syntactic/semantic
matching. With recent developments in Machine learning and Natural Language
Processing, we motivate the use of Sentence Embeddings by leveraging richer
semantic representations of sentences for service description, matching and
retrieval. Experimental results show that service composition development
effort may be reduced by more than 44\% while keeping a high precision/recall
when matching high-level user requests with low-level service method
invocations.Comment: This paper will appear on SCC'19 (IEEE International Conference on
Services Computing) on July 1
KCDC - The KASCADE Cosmic-ray Data Centre
KCDC, the KASCADE Cosmic-ray Data Centre, is a web portal, where data of
astroparticle physics experiments will be made available for the interested
public. The KASCADE experiment, financed by public money, was a large-area
detector for the measurement of high-energy cosmic rays via the detection of
air showers. KASCADE and its extension KASCADE-Grande stopped finally the
active data acquisition of all its components including the radio EAS
experiment LOPES end of 2012 after more than 20 years of data taking. In a
first release, with KCDC we provide to the public the measured and
reconstructed parameters of more than 160 million air showers. In addition,
KCDC provides the conceptional design, how the data can be treated and
processed so that they are also usable outside the community of experts in the
research field. Detailed educational examples make a use also possible for
high-school students and early stage researchers.Comment: 8 pages, accepted proceeding of the ECRS-symposium, Kiel, 201
