One of the key requirements to facilitate semantic analytics of information regarding contemporary and historical events on the Web, in the news and in social media is the availability of reference knowledge repositories containing comprehensive representations of events and temporal relations. Existing knowledge graphs, with popular examples including DBpedia, YAGO and Wikidata, focus mostly on entity-centric information and are insufficient in terms of their coverage and completeness with… 
EventKG - the Hub of Event Knowledge on the Web - and Biographical Timeline Generation
TLDR
An application of EventKG to biographical timeline generation, where it is demonstrated to adopt a distant supervision method to identify relations most relevant for an entity biography and the effectiveness of the proposed biographical Timeline generation method is demonstrated.
EventKG+TL: Creating Cross-Lingual Timelines from an Event-Centric Knowledge Graph
TLDR
This paper presents \eventTL{} - a novel system that generates cross-lingual event timelines using EventKG and facilitates an overview of the language-specific event relevance and popularity along with the cross-lingsual differences.
What is Event Knowledge Graph: A Survey
TLDR
To characterize EKG thoroughly, this paper focuses on its history, definitions, schema induction, acquisition, related representative graphs/systems, and applications, and the development processes and trends are studied therein.
EventNarrative: A large-scale Event-centric Dataset for Knowledge Graph-to-Text Generation
TLDR
The aim of this paper is to help break new ground in event-centric research where data is lacking and to give researchers a well-defined, large-scale dataset in order to better evaluate existing and future knowledge graph-to-text models.
From Discourse to Narrative: Knowledge Projection for Event Relation Extraction
TLDR
This paper proposes Multi-tier Knowledge Projection Network (MKPNet), which can leverage multi-tier discourse knowledge effectively for event relation extraction, and shows that MKPNet achieves the new state-of-the-art performance and extrinsic experimental results verify the value of the extracted event relations.
Comprehensive Event Representations using Event Knowledge Graphs and Natural Language Processing
TLDR
Sub-event extraction is used as a way of creating sub-event-aware event representations, which are further enriched through fine-grained location extraction and contextualised through the alignment of historically relevant quotes.
Searching News Articles Using an Event Knowledge Graph Leveraged by Wikidata
TLDR
A general method that leverages the Wikidata knowledge base to produce semantic annotations of news articles is proposed and a semantic search engine that supports both keyword based search in news articles and structured data search providing filters for properties belonging to specific event schemas is described.
Towards Better Understanding Researcher Strategies in Cross-Lingual Event Analytics
TLDR
This paper presents researchers’ strategies for the content, method and feature selection in the context of cross-lingual event-centric analytics observed in two case studies on multilingual Wikipedia.
Towards extracting event-centric collections from Web archives
TLDR
This article addresses the novel problem of extracting interlinked event-centric document collections from large-scale Web archives to facilitate an efficient and intuitive access to information regarding past events by developing a specialised extraction method that adapts focused crawling techniques to the Web archive settings.

EventKG+TL: Creating Cross-Lingual Timelines from an Event-Centric Knowledge Graph
TLDR

Building event-centric knowledge graphs from news
Automatic Classification and Relationship Extraction for Multi-Lingual and Multi-Granular Events from Wikipedia
TLDR
This paper focuses on extending the prior method for extracting events for a daily granularity, the automatic classification of events and finding relationships between events and automatically built categories for about 70% of the events of another language set.
A Fresh Look on Knowledge Bases: Distilling Named Events from News
TLDR
This paper presents a method for extracting named events from news articles, reconciling them into canonicalized representation, and organizing them into fine-grained semantic classes to populate a knowledge base.
Introducing Wikidata to the Linked Data Web
TLDR
New RDF exports that connect Wikidata to the Linked Data Web are introduced and several partial exports are introduced that provide more selective or simplified views on the data.
LODE: Linking Open Descriptions of Events
TLDR
A model for publishing records of events as Linked Data is described, which can be used to locate stable URIs for events that have occurred, provide RDFS+OWL descriptions and link to related resources.
Ongoing Events in Wikipedia: A Cross-lingual Case Study
TLDR
Preliminary results of a case study are presented with the goal to better understand how researchers interact with multilingual event-centric information in the context of cross-cultural studies and which methods and features they use.
TimeMachine: Timeline Generation for Knowledge-Base Entities
TLDR
This work develops three orthogonal timeline quality criteria that an ideal timeline should satisfy, and presents an algorithm to generate such timelines for a given time period and screen size, based on submodular optimization and web-co-occurrence statistics with provable performance guarantees.
DBpedia - A large-scale, multilingual knowledge base extracted from Wikipedia
TLDR
An overview of the DBpedia community project is given, including its architecture, technical implementation, maintenance, internationalisation, usage statistics and applications, including DBpedia one of the central interlinking hubs in the Linked Open Data (LOD) cloud.
Indexing and analyzing wikipedia's current events portal, the daily news summaries by the crowd
TLDR
The results show that WCEP has reached a stable state in terms of the volume of contributions as well as the size of its crowd, which makes it an important source of news summaries for the public and the research community.
