In this paper we introduce the Beam Search CRM (BS-CRM) model. This model implements two novel improvements to the basic CRM [2]. First, we argue that using a Minkowski kernel allows us to capture the covariance of visual features more effectively than the standard Gaussian kernel. Second, we advocate a procedure that selects the most informative subset of tags as the image annotation. Our proc...

Purpose – Many Web 2.0 services (including Library 2.0 catalogs) make use of folksonomies. The purpose of this paper is to cut off all tags in the long tail of a document-specific tag distribution. The remaining tags at the beginning of a tag distribution are considered power tags and form a new, additional search option in information retrieval systems. Design/methodology/approach – In a theor...

This paper presents the analysis, design and experimental evaluation of miniaturized magnetoelastic tags using frame-suspended hexagonal resonators. Magnetoelastic tags—also known as acousto-magnetic or magnetomechanical tags—are used in wireless detection systems—for example, electronic article surveillance and location mapping systems—that electromagnetically query the resonant response of th...

Radio frequency identification systems with passive tags dramatically increase the ability of an organization to acquire a vast array of data about the location and properties of any entity that can be physically tagged and wirelessly scanned within certain technical limitations. However, if multiple tags are to be identified simultaneously, messages from the tags can collide and cancel each ot...

Games with a purpose (GWAPs) are increasingly used in audio-visual collections as a mechanism for annotating videos through tagging. This trend is driven by the assumption that user tags will improve video search. In this paper we study whether this is indeed the case. To this end, we create an evaluation dataset that consists of: (i) a set of videos tagged by users via video labelling game, (i...

In this report,we propose a method for recommending tags of images.The proposed method presents to the user various tags with high precision by taking into account both the co-occurrence of tags and similar images. Additional search with the user feedback enables us to find some new tags relevant to the image of interest.In order to test the proposed method,we compare it with a method based onl...

This paper describes the results of a study whose goal is to analyze, evaluate and understand the use of semantics in social networks. As a paradigmatic example, the study concentrates on a fairly large portion of the tags used in del.icio.us (more than 5,000 tags). The results show that semantics are pervasively used. In particular, the large majority (in our experiment, 75%) of the tags are s...

There are millions of users who tag multimedia content, generating a large vocabulary of tags. Some tags are frequent, while other tags are rarely used following a long tail distribution. For frequent tags, most of the multimedia methods that aim to automatically understand audio-visual content, give excellent results. It is not clear, however, how these methods will perform on rare tags. In th...

We show that categories induced by unsupervised word clustering can surpass the performance of gold part-of-speech tags in dependency grammar induction. Unlike classic clustering algorithms, our method allows a word to have different tags in different contexts. In an ablative analysis, we first demonstrate that this context-dependence is crucial to the superior performance of gold tags — requir...
