Adding semantics to microblog posts

Edgar Meij, Wouter Weerkamp, Maarten de Rijke
2012 Proceedings of the fifth ACM international conference on Web search and data mining - WSDM '12  
We propose a solution to the problem of determining what a microblog post is about through semantic linking: we add semantics to posts by automatically identifying concepts that are semantically related  ...  Using a purpose-built test collection of tweets, we show that recently proposed approaches for semantic linking do not perform well, mainly due to the idiosyncratic nature of microblog posts.  ...  See wsdm2012-adding-semantics-to-microblog-posts/. See  ...

Chinese Microblog Topic Detection through POS-Based Semantic Expansion

Lianhong Ding, Bin Sun, Peng Shi
2018 Information  
The semantic expansion of the post supplies more information and clues for topic detection. First, semantic features are extracted from a microblog post.  ...  Since traditional methods showed low performance on a short text from a microblog, we put forward a topic detection method based on the semantic description of the microblog post.  ...  If semantics are added to microblog posts through TYCCL, a post is represented as a set of feature items and their weights.  ...

Rethinking Microblogging: Open, Distributed, Semantic [chapter]

Alexandre Passant, John G. Breslin, Stefan Decker
2010 Lecture Notes in Computer Science  
In this paper, we detail the anatomy of SMOB, a distributed semantic microblogging framework.  ...  There needs to be a focus on the one hand on distributed architectures -so that users remain owners of their data -and on the other hand on means to semantically-enhance their content -so that it becomes  ...  We would like to thanks Uldis Bojārs and Tuukka Hastrup for their involvement in SIOC and in the first version of SMOB as well as Milan Stankovic and Philippe Laublet for their work on OPO.  ...

miKrow: Semantic Intra-enterprise Micro-Knowledge Management System [chapter]

Víctor Penela, Guillermo Álvaro, Carlos Ruiz, Carmen Córdoba, Francesco Carbone, Michelangelo Castagnone, José Manuel Gómez-Pérez, Jesús Contreras
2011 Lecture Notes in Computer Science  
In this paper, a lightweight framework for Knowledge Management is proposed based on the combination of two layers that cater to each need: a microblogging layer that simplifies how users interact with  ...  the whole system and a semantic powered engine that performs all the intelligent heavy lifting by combining semantic indexing and search of messages and users.  ...  This search returns messages semantically relevant to the one that the user has just posted.  ...

2013 Communications in Computer and Information Science  
We validate the proposed method by linking 1232 entities mined from Sina Weibo to a Chinese Semantic knowledge base, resulting in an accuracy of 88.5%.  ...  In this paper, we propose an entity linking method based on Chinese Semantic Knowledge where entity disambiguation can be addressed by retrieving a variety of semantic relations and analyzing the corresponding  ...  Secondly, in order to make a balance between the contents of a microblog post and the wiki page contents in the knowledge base, we attempt to make an understanding of microblog posts by adding relevant  ...

Mining the Personal Interests of Microbloggers via Exploiting Wikipedia Knowledge [chapter]

Miao Fan, Qiang Zhou, Thomas Fang Zheng
2014 Lecture Notes in Computer Science  
Previous studies regarded the microblogs posted by one microblogger as a whole document and adopted traditional keyword extraction approaches to select high weighting nouns without considering the characteristics  ...  Based on the semantic graph constructed via the Wikipedia, the proposed semantic spreading model (SSM) can discover and leverage the semantically related interest tags which do not occur in one's microblogs  ...  Representative platforms such as Twitter and Sina Weibo allow users to freely post 140 English characters and Chinese words respectively in one microblog.  ...

Ubiquitous Microblogging: A Flow-Based Front-End for Information Logistics [chapter]

Martin Böhringer, Martin Gaedke
2010 Lecture Notes in Business Information Processing  
Beyond the Web 2.0 tool family, in particular microblogging could show a perfect match with Information Logistics scenarios due to its adhoc character and its simplicity.  ...  To allow ordinary users to participate, there is a clear need for simple but yet powerful front-end technology.  ...  An alternative to semantic markup of microblogging postings is to understand the meanings of natural language using Natural Language Processing (NLP).  ...

Microblog-HAN: A micro-blog rumor detection model based on heterogeneous graph attention network

Bei Bi, Yaojun Wang, Haicang Zhang, Yang Gao, Sathishkumar V E
2022 PLoS ONE  
Moreover, semantic-level attention fuses different semantics to obtain the final node embedding of the microblog, which is then used as a classifier's input.  ...  Specifically, after the initial textual and visual features of posts are extracted, the node-level attention mechanism combines neighbors of the microblog nodes to generate three groups of node embeddings  ...  Still, these methods seldomly consider the multimedia form of a microblog and fail to explore the semantic information of microblog information's spreading path fully.  ...

Jing Li, Zhongyu Wei, Hao Wei, Kangfei Zhao, Junwen Chen, Kam-Fai Wong
2015 Lecture Notes in Computer Science  
We combine content-based, microblog-specific and temporal features into learning to rank models, which are found to model microblog posts effectively.  ...  In the era of Big Data, we are overwhelmed by the large amount of microblog posts. To make good use of these informative data, an effective search tool is required specialized for microblog posts.  ...  In the future, we will take the semantic information inside the query term and microblog posts content into consideration.  ...

MIKE: An Interactive Microblogging Keyword Extractor using Contextual Semantic Smoothing

Osama Khan, Asim Karim
2012 International Conference on Computational Linguistics  
In this paper we present MIKE, a robust interactive system for keyword extraction from single microblog posts, which uses contextual semantic smoothing; a novel technique that considers term usage patterns  ...  Social media, such as tweets on Twitter and Short Message Service (SMS) messages on cellular networks, are short-length textual documents (short texts or microblog posts) exchanged among users on the Web  ...  Due to the short length of microblog posts, we assume the co-occurrence window size to be the document length.  ...
