Scientists always look for the most accurate and relevant answers to their queries in the literature. Traditional scholarly digital libraries list documents in search results, and therefore are unable to provide precise answers to search queries. In other words, search in digital libraries is metadata search and, if available, full-text search. We present a methodology for improving a faceted search system on structured content by leveraging a federation of scholarly knowledge graphs. We… 

Enriching Scholarly Knowledge with Context

A novel web widget based approach for the presentation of scholarly knowledge with rich contextual information sourced in a federated manner from numerous technologically heterogeneous scholarly communication infrastructures is developed.

Knowledge Graph Induction enabling Recommending and Trend Analysis: A Corporate Research Community Use Case

This paper presents a use case of how a corporate research community, IBM Research, utilizes Semantic Web technologies to induce a Knowledge Graph from both structured and textual data obtained by integrating various applications used by the community related to research projects, academic papers, datasets, achievements and recognition.



Faceted search over RDF-based knowledge graphs

Creating a Scholarly Knowledge Graph from Survey Article Tables

A human-in-the-loop methodology used to build a scholarly knowledge graph leveraging literature survey articles, demonstrating the feasibility of the approach, but also indicating that manual effort is required and thus underscore the important role of human experts.

Towards a Definition of Knowledge Graphs

This work discusses and defines the term knowledge graph, considering its history and diversity in interpretations and use, and proposes a definition of knowledge graphs that serves as basis for discussions on this topic and contributes to a common vision.

Towards a Knowledge Graph Representing Research Findings by Semantifying Survey Articles

This article describes how surveys for research fields can be represented in a semantic way, resulting in a knowledge graph that describes the individual research problems, approaches, implementations and evaluations in a structured and comparable way and demonstrates the utility of the resulting knowledge graph.

Knowledge Graphs on the Web - an Overview

This chapter provides an overview and comparison of those publicly available knowledge graphs, and gives insights into their contents, size, coverage, and overlap.

Open Research Knowledge Graph: Next Generation Infrastructure for Semantic Scholarly Knowledge

The first steps towards a knowledge graph based infrastructure that acquires scholarly knowledge in machine actionable form are presented thus enabling new possibilities for scholarly knowledge curation, publication and processing.

Faceted Search with Object Ranking and Answer Size Constraints

This article proposes an extension of the model with two parameters that enable specifying the desired answer size and the granularity of the sought object ranking, and provides an algorithm that produces an object ranking that satisfies these parameters, in a transparent way for the user.

A Survey of Faceted Search

This paper first analyzes the representative facet search models, then presents a general faceted search framework, and surveys the related methods and techniques, including facet term extraction, hierarchy construction, compound term generation and facet ranking.

Minimum-effort driven dynamic faceted search in structured databases

This paper proposes minimum-effort driven navigational techniques for enterprise database systems based on the faceted search paradigm that dynamically suggest facets for drilling down into the database such that the cost of navigation is minimized.

Open Research Knowledge Graph: A System Walkthrough

The core functionality of ORKG for representing research contributions published in scholarly articles is demonstrated and the Open Research Knowledge Graph is demonstrated as an infrastructure for representing, curating and exploring scholarly knowledge in a machine actionable manner.
