Social tags

Proceedings of the 17th ACM conference on Information and knowledge management, 2008
This paper aims to quantify two common assumptions about social tagging: (1) that tags are "meaningful" and (2) that the tagging process is influenced by tag suggestions. For (1), we analyze the semantic properties of tags and the relationship between the tags and the content of the tagged page.

Social tag prediction

Proceedings of the 31st annual international ACM SIGIR conference on Research and development in information retrieval, 2008
In this paper, we look at the "social tag prediction" problem. Given a set of objects, and a set of tags applied to those objects by users, can we predict whether a given tag could/should be applied to a particular object? We investigated this question using one of the largest crawls of the social bookmarking system del.icio.us gathered to date.

Tags vs shelves

Proceedings of the 22nd ACM conference on Hypertext and hypermedia, 2011
Recent research has shown that different tagging motivation and user behavior can effect the overall usefulness of social tagging systems for certain tasks. In this paper, we provide further evidence for this observation by demonstrating that tagging data obtained from certain types of users - so-called Categorizers - outperforms data from other users ...

Identifying Consensus Tags in Social Tagging Systems

2011 IEEE Ninth International Conference on Dependable, Autonomic and Secure Computing, 2011
Social Tagging is a free but also uncontrolled way to index and organize Web 2.0 resources. Many works have been proposed to leverage such tagging information. However, although previous studies have shown that users could reach consensus on which tags should be attached to a resource, the study about the consensus showing how to use a tag is still ...

Mining tag semantics for social tag recommendation

2011 IEEE International Conference on Granular Computing, 2011
Nowadays lots of information are stored as Web pages for ease of sharing and searching. It is rather impractical for users to browse such gigantic amount of Web pages to obtain target information. Therefore, users often count on search engines to retrieve information they needed.

Survey on social tagging techniques

SIGKDD Explorations: Newsletter of the Special Interest Group (SIG) on Knowledge Discovery & Data Mining, 2010
Social tagging on online portals has become a trend now. It has emerged as one of the best ways of associating metadata with web objects. With the increase in the kinds of web objects becoming available, collaborative tagging of such objects is also developing along new dimensions. This popularity has led to a vast literature on social tagging. In this

From keywords to social tags: Tagging for dialogues

2011 7th International Conference on Natural Language Processing and Knowledge Engineering, 2011
This paper proposes an unsupervised method for generating informative tags for multi-party dialogue in an open domain. Our model first extracts keywords from text through a multi-weighting framework, which includes frequency weighting, sentence weighting, speaker weighting and position weighting.

Semantic imitation in social tagging [PDF]

open access: yesACM Transactions on Computer-Human Interaction, 2010
We present a semantic imitation model of social tagging and exploratory search based on theories of cognitive science. The model assumes that social tags evoke a spontaneous tag-based topic inference process that primes the semantic interpretation of resource contents during exploratory search, and the semantic ...
