Contextualized ranking of entity types based on knowledge graphs

Alberto Tonon, Michele Catasta, Roman Prokofyev, Gianluca Demartini, Karl Aberer, Philippe Cudré-Mauroux
2016 Journal of Web Semantics  
In this paper, we define the new task of ranking entity types given an entity and its context.  ...  However, an entity is usually not associated to a single generic type in the background knowledge graph but rather to a set of more specific types, which may be relevant or not given the document context  ...  Then, we introduce the most important concepts in the Web of Data (Section 3) to formally define our new type ranking task in Section 4.  ...

Roman Prokofyev, Alberto Tonon, Michael Luggen, Loic Vouilloz, Djellel Eddine Difallah, Philippe Cudré-Mauroux
2015 Lecture Notes in Computer Science  
Finally, we use the semantic relatedness of the introduced types to improve the stateof-the-art techniques by splitting and merging coreference clusters.  ...  Then, we propose an approach to type noun phrases using an inverted index built on top of a Knowledge Graph (e.g., DBpedia).  ...  This work was supported by the Swiss National Science Foundation under grant number PP00P2 153023, and by the Haslerstiftung in the context of the Smart World 11005 (Mem0r1es) project.  ...

Scalable Link-based Personalization for Ranking in Entity-Relationship Graphs

Vagelis Hristidis, Louiqa Raschid, Yao Wu
2011 International Workshop on the Web and Databases  
Authority flow techniques like PageRank and ObjectRank can provide personalized ranking of typed entity-relationship graphs.  ...  We propose for the first time an approach to achieve efficient edge-based personization using a combination of precomputation and runtime algorithms.  ...  INTRODUCTION The success of PageRank [1] in ranking Web pages resulted in many flavors of authority flow-based ranking techniques for data in entity-relationship graphs [2, 3, 4, 5] .  ...

Enhancing Search with Structure

Soumen Chakrabarti, Sunita Sarawagi, S. Sudarshan
2010 IEEE Data Engineering Bulletin  
In recent years, there has been a good deal of work that attempts to go beyond the above paradigms, to improve search experience on unstructured textual data as well as on structured or semi-structured  ...  Similarly, work on keyword queries on structured data has focussed on retrieving closely connected pieces of data that together contain given query keywords.  ...  Entity nodes may be explicitly connected by edges to a type "meta data" node, or the type may be interpreted as a discrete attribute of the entity node.  ...

Gleaning Types for Literals in RDF Triples with Application to Entity Summarization [chapter]

Kalpa Gunaratna, Krishnaprasad Thirunarayan, Amit Sheth, Gong Cheng
2016 Lecture Notes in Computer Science  
Associating meaning with data in a machine-readable format is at the core of the Semantic Web vision, and typing is one such process.  ...  We show the usefulness of generated types by utilizing them to group facts on the basis of their semantics in computing diversified entity summaries by extending a state-of-the-art summarization algorithm  ...  Any opinions, findings, and conclusions/recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the NSF.  ...

Mazen Alsarem, Pierre-Edouard Portier, Sylvie Calabretto, Harald Kosch
2015 Lecture Notes in Computer Science  
We use crowdsourcing for building a publicly available and reusable dataset for the evaluation of query-biased ranking of Web of data resources detected in Web pages.  ...  and the Web of data.  ...  Finally, TRank [27] addresses the task of ranking entity types given an initial entity and its textual context.  ...

Entity Summarization: State of the Art and Future Challenges [article]

Qingxia Liu, Gong Cheng, Kalpa Gunaratna, Yuzhong Qu
2021 arXiv   pre-print
The increasing availability of semantic data has substantially enhanced Web applications. Semantic data such as RDF data is commonly represented as entity-property-value triples.  ...  The magnitude of semantic data, in particular the large number of triples describing an entity, could overload users with excessive amounts of information.  ...  However, we do not use Semantic Web terms in this article because entity summarization is not specific to semantic data that complies with Semantic Web standards.  ...

deepschema.org: An Ontology for Typing Entities in the Web of Data

Panayiotis Smeros, Amit Gupta, Michele Catasta, Karl Aberer
2017 The Web Conference  
Discovering the appropriate type of an entity in the Web of Data is still considered an open challenge, given the complexity of the many tasks it entails.  ...  Furthermore, the generation of the ontology must follow an automated fashion, combining the most widely used data sources and following the speed of the Web.  ...  ACKNOWLEDGEMENTS This work was partially supported by the project "Exploring the interdependence between scientific and public opinion on nutrition through large-scale semantic analysis" from the Integrative  ...

Seyed Amin Pouriyeh, Mehdi Allahyari, Krys Kochut, Gong Cheng, Hamid R. Arabnia
2017 International Joint Conference on Natural Language Processing  
With the advent of the Internet, the amount of Semantic Web documents that describe real-world entities and their inter-links as a set of statements have grown considerably.  ...  We demonstrate the effectiveness of our approach by conducting extensive experiments and show that our model outperforms the state-of-the-art techniques and enhances the quality of the entity summaries  ...  Acknowledgments Gong Cheng was partially funded by the NSFC under Grant 61572247.  ...

Qunits: queried units in database search [article]

Arnab Nandi, H V Jagadish (University of Michigan)
2009 arXiv   pre-print
As a consequence, when keyword queries are attempted against databases, relatively ad-hoc ranking mechanisms are invented (if ranking is used at all), and there is little leverage from the large body of  ...  We provide insights that encourage the use of this query paradigm, and discuss preliminary investigations into the efficacy of a qunits-based framework based on a prototype implementation.  ...  Objec-tRank, on the other hand, combines tuple-level PageRank from a pre-computed data graph with keyword matching.  ...

An EBMC-Based Approach to Selecting Types for Entity Filtering

Jiwei Ding, Wentao Ding, Wei Hu, Yuzhong Qu
2015 PROCEEDINGS OF THE THIRTIETH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE AND THE TWENTY-EIGHTH INNOVATIVE APPLICATIONS OF ARTIFICIAL INTELLIGENCE CONFERENCE  
The quantity of entities in the Linked Data is increasing rapidly. For entity search and browsing systems, filtering is very useful for users to find entities that they are interested in.  ...  Type is a kind of widely-used facet and can be easily obtained from knowledge bases, which enables to create filters by selecting at most K types of an entity collection.  ...  Gong Cheng for his valuable suggestion on the design of our experiments, and Yong Wang for his help on evaluation. We are also grateful to all participants in the evaluation for their time and effort.  ...
