Leveraging the Semantics of Tweets for Adaptive Faceted Search on Twitter [chapter]

Fabian Abel, Ilknur Celik, Geert-Jan Houben, Patrick Siehndel
2011 Lecture Notes in Computer Science  
We propose strategies for inferring facets and facet values on Twitter by enriching the semantics of individual Twitter messages (tweets) and present different methods, including personalized and context-adaptive  ...  In the last few years, Twitter has become a powerful tool for publishing and discussing information. Yet, content exploration in Twitter requires substantial effort.  ...  By choosing from the suggested facet-values, a user can interactively refine the query.  ...

Crisis and Disaster Situations on Social Media Streams: An Ontology-Based Knowledge Harvesting Approach

2019 Interdisciplinary Journal of Information, Knowledge, and Management  
Hence, the pervasive use of ontology is highly suggested that build semantic-oriented metadata for concept-based modeling, information flow searching and knowledge exchange.  ...  Besides, the proposed method makes use of SPARQL to disambiguate the query and yield the results which produce high precision.  ...  In the following sections, we present semantic filtering of entities from Twitter streams and identifying the potential meaning of tweets using domain ontology.  ...

Discovering similar Twitter accounts using semantics [article]

Gerasimos Razis, Ioannis Anagnostopoulos
2015 arXiv   pre-print
Towards this direction, we introduce a methodology for discovering and suggesting similar Twitter accounts, based entirely on their disseminated content in terms of Twitter entities used.  ...  Many of these entities are used in common by many accounts.  ...  -how-to-use-twitter-s-suggestions-for-who-to-follow  ...

TUMS: Twitter-Based User Modeling Service [chapter]

Ke Tao, Fabian Abel, Qi Gao, Geert-Jan Houben
2012 Lecture Notes in Computer Science  
In this paper, we introduce TUMS, a Twitter-based User Modeling Service, that infers semantic user profiles from the messages people post on Twitter.  ...  It allows end-users to overview Twitter-based profiles in a structured way and allows them to see in which topics or entities a user was interested in a specific point in time.  ...  [11] proposed to exploit contextual information to enrich the semantics of Twitter messages. In previous work, we followed this suggestion and linked tweets to related Web resources [12] .  ...

The iCrawl Wizard – Supporting Interactive Focused Crawl Specification [chapter]

Gerhard Gossen, Elena Demidova, Thomas Risse
2015 Lecture Notes in Computer Science  
Using the iCrawl Wizard even non-expert users can create semantic specifications for focused crawlers interactively and efficiently.  ...  Our tool uses major search engines and Social Media APIs as well as information extraction techniques to find seed URLs and a semantic description of the crawl intent.  ...  Additionally, it uses information extraction tools to suggest representative keywords and entities for the semantic crawl specification.  ...

Modeling Influence with Semantics in Social Networks: a Survey [article]

Gerasimos Razis, Ioannis Anagnostopoulos, Sherali Zeadally
2018 arXiv   pre-print
The discovery of influential entities in all kinds of networks (e.g. social, digital, or computer) has always been an important field of study.  ...  In this work, we present a systematic review across i) online social influence metrics, properties, and applications and ii) the role of semantic in modeling OSNs information.  ...  Specifically, we propose an algorithmic approach, which expands a user's query by creating a suggestion set of the most viral and up-to-date Twitter entities (e.g. hashtags, user mentions, URLs, etc.).  ...

Learning Semantic Relationships between Entities in Twitter [chapter]

Ilknur Celik, Fabian Abel, Geert-Jan Houben
2011 Lecture Notes in Computer Science  
In this paper, we investigate whether semantic relationships between entities can be learnt from analyzing microblog posts published on Twitter.  ...  We identify semantic links between persons, products, events and other entities.  ...  Furthermore, when people search in Twitter, our framework can identify entities mentioned in a keyword query and exploit relationships to other entities to provide query suggestions to the user.  ...
