Target Type Identification for Entity-Bearing Queries

Identifying the target types of entity-bearing queries can help improve retrieval performance as well as the overall search experience. In this work, we address the problem of automatically detecting the target types of a query with respect to a type taxonomy. We propose a supervised learning approach with a rich variety of features. Using a purpose-built test collection, we show that our approach outperforms existing methods by a remarkable margin.

Semantic metrics

In the context of the Semantic Web, many ontology-related operations, e.g. ontology ranking, segmentation, alignment, articulation, reuse, evaluation, can be boiled down to one fundamental operation: computing the similarity and?or dissimilarity among ontological entities, and in some cases among ontologies themselves. In this paper, we review standard metrics for computing distance measures and we propose a series of semantic metrics. We give a formal account of semantic metrics drawn from a variety of research disciplines, and enrich them with semantics based on standard Description Logic constructs. We argue that concept-based metrics can be aggregated to produce numeric distances at ontology-level and we speculate on the usability of our ideas through potential areas

Council of the Baltic Sea States: The Role of a Sustainable and Prosperous Region in Bringing Science Diplomacy Forward. EL-CSID Working Paper Issue 2018/19 • July 2018

2017 has been a year full of promising major milestones for the future EU Science Diplomacy Strategy. At the beginning of 2017, the Directorate-General for Research and Innovation (DG RTD) of the European Commission released a thought-provoking report Tools for an EU science diplomacy (Van Langenhove, 2017). This publication was accompanied with a recognition among some parts of the academic circles and practitioners that the "Union is in process of reinforcing its diplomacy for science (the classical international S&T cooperation), while developing a genuine science for diplomacy" (López de San Román & Schunz, 2018, p. 262). Later on others have called the subsequent developments a worldwide "jump on the “science diplomacy” bandwagon" (Penca, 2018, p. 1). In the Baltic Sea Region setting, on 20 June 2017, the Reykjavík Ministerial of the Council of the Baltic Sea States (CBSS) took place and resulted in a Declaration on the Occasion of the 25th Anniversary of the CBSS (CBSS, 2017), as well as the endorsement of Realizing the Vision: Baltic 2030 Action Plan (CBSS Secretariat, 2017), which serves as "a solid basis for concrete CBSS action to meet the Sustainable Development Goals at regional level" (CBSS, 2017, p. 2). The report Tools for an EU science diplomacy outlines promising recommendations for further assembly of cases, which might serve as reference points or potential sources of inspiration once crafting the main structures and guidance enshrined in the upcoming 'EU Science Diplomacy Strategy'. As it will be outlined in subsequent paragraphs, the CBSS-endorsed multilateral cooperation initiatives have spurred various macro-regional dynamics of implicit science diplomacy,1 which might serve as a source of inspiration in the crafting of certain elements for the forthcoming strategy

On the use of clustering and the MeSH controlled vocabulary to improve MEDLINE abstract search

Databases of genomic documents contain substantial amounts of structured information in addition to the texts of titles and abstracts. Unstructured information retrieval techniques fail to take advantage of the structured information available. This paper describes a technique to improve upon traditional retrieval methods by clustering the retrieval result set into two distinct clusters using additional structural information. Our hypothesis is that the relevant documents are to be found in the tightest cluster of the two, as suggested by van Rijsbergen's cluster hypothesis. We present an experimental evaluation of these ideas based on the relevance judgments of the 2004 TREC workshop Genomics track, and the CLUTO software clustering package

Computer Programs, User Interfaces, and Section 102(b) of the Copyright Act of 1976: A Critique of Lotus v. Paperback

The Supreme Court\u27s landmark ruling Lotus Development Corp vs Paperback Software International is critiqued. The ruling did not resolve the issue of whether copyright law protects user interfaces

Levinas, Simmel, and the Ethical Significance of Money

An examination of Emmanuel Levinas’ writings on money reveals his distance from—and indebtedness to—a philosophical predecessor, Georg Simmel. Levinas and Simmel share a phenomenological approach to analyses of the proximity of the stranger, the importance of the face, and the interruption of the dyadic relationship by the third. Money is closely linked to the conception of totality because money is the medium that compares heterogeneous values. Levinas goes beyond Simmel in positing an ethical relation to money permitting transcendence
