Towards Semantic Retrieval of Hashtags in Microblogs
2015
Proceedings of the 24th International Conference on World Wide Web - WWW '15 Companion
In this poster, we propose and evaluate a novel method of semantic enrichment of microblogs for a particular type of entity search -retrieving a ranked list of the top-k hashtags relevant to a user's query ...
We observed an improvement of more than 10% in NDCG for microblog retrieval task, and around 11% in mean average precision for hashtag retrieval task. ...
CONCLUSIONS AND FUTURE WORK We have presented and evaluated a semantic search system in context of hashtag and microblog retrieval. ...

Semantic query suggestion using Twitter Entities
2015
Neurocomputing
Towards this direction, we introduce an algorithmic approach capable of creating a dynamic query suggestion set, which consist of the most viral and trendy Twitter Entities (that is hashtags, user mentions ...
However, the penetration of microblogging services in our daily life demands to also consider social sphere as far as query suggestion is concerned. ...

Adding semantics to microblog posts
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. ...
[16] analyze the semantics of hashtags in more detail and reveal that hashtagging in Twitter is more commonly used to join public discussions than to organize content for future retrieval. ...

Information search and retrieval in microblogs
2011
Journal of the American Society for Information Science and Technology
After an overview of microblogs and the behavior surrounding them, the article describes established problems in microblog retrieval such as entity search, sentiment analysis, and modeling abstractions ...
Modern information retrieval (IR) has come to terms with numerous new media in efforts to help people find information in increasingly diverse settings. ...
Thus in microblog IR, the unit of retrieval is often either non-obvious or in need of formalizing to permit tractable retrieval. ...

HyperTwitter: Collaborative Knowledge Engineering via Twitter Messages
[chapter]
2010
Lecture Notes in Computer Science
A recent trend in the evolution of the Web is the massive contribution of small chunks of content by regular users, typically in combination with mechanisms for fostering social interaction. ...
The resulting RDF graphs can be combined easily with other Semantic Web data. ...
In Twitter, hashtags have a stronger global reach than in other social tagging systems, because one does not invent tags for personal retrieval but for being visible by others. ...

HU DB at TREC 2014 Microblog Track
2014
Text Retrieval Conference
This paper describes our system for the Tweet Timeline Generation (TTG) task of the Microblog track, at the Text Retrieval Conference (TREC) 2014. ...
Intuitively, given a collection of microblog posts (i.e., tweets), and a keyword query Q, the goal is to generate a timeline of related tweets. ...

Improving LDA topic models for microblogs via tweet pooling and automatic labeling
2013
Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '13
We empirically establish that a novel method of tweet pooling by hashtags leads to a vast improvement in a variety of measures for topic coherence across three diverse Twitter datasets in comparison to ...
An additional contribution of automatic hashtag labeling further improves on the hashtag pooling results for a subset of metrics. ...

What Makes a Tweet Relevant for a Topic?
2012
Workshop on Making Sense of Microposts
Our in-depth analysis compares the importance of the different types of features and reveals that semantic features and therefore an understanding of the semantic meaning of the tweets plays a major role ...
Users who rely on microblogging search (MS) engines to find relevant microposts for their queries usually follow their interests and rationale when deciding whether a retrieved post is of interest to them ...
Twitter users typically apply hashtags in order to facilitate the retrieval of the tweet. For example, by using a hashtag people can join a discussion on a topic that is represented via that hashtag. ...

A Tweets Classifier based on Cosine Similarity
2017
Conference and Labs of the Evaluation Forum
The 2017 Microblog Cultural Contextualization task consists in three challenges: (1) Content Analysis, (2) Microblog search, and (3) TimeLine illustration. ...
This paper describes the use of cosine similarity, which is characterized by the comparison of similarity between two vectors of an inner product space. ...
In related research, Murtagh [8] used correspondence analysis to map the dual spaces of days and hashtags to a latent semantic space with social narratives information, and related work on Pierre Bourdieu ...

Exploiting Meta Attributes for Identifying Event Related Hashtags
2017
Proceedings of the 9th International Joint Conference on Knowledge Discovery, Knowledge Engineering and Knowledge Management
A learning to rank algorithm is applied to learn the importance weights of the features towards the task of predicting the relevance of a hashtag to the given event. ...
Finding event related hashtags can be useful for this purpose. In this paper, we focus on the problem of finding relevant hashtags for a given event. ...
The work shows that identification of semantic relatedness between the hashtag and the event metadata helps in better retrieval of relevant hashtags. ...

Emergent Case Management for Ad-hoc Processes: A Solution Based on Microblogging and Activity Streams
[chapter]
2011
Lecture Notes in Business Information Processing
We theoretically derive characteristics of such a system and demonstrate the approach based on a toolset of current Social Software techniques including microblogging, activity streams and tagging. ...
In addition to existing top-down approaches, this paper suggests a bottom-up view on Case Management that leverages emergent user-driven case handling. ...
Therefore, a strong technological foundation in terms of semantics and open standards is necessary. ...
