1 Social tags in web 2.0 are becoming another important information source to describe the content of items as well as to profile users’ topic preferences. However, as arbitrary words given by users, tags contains a lot of noise such as tag synonym and semantic ambiguity a large number personal tags that only used by one user, which brings challenges to effectively use tags to make item recomme...

The objective of our group was to exploit state-of-the-art Information Retrieval methods for finding associations and dependencies between tags, capturing and representing differences in tagging behavior and vocabulary of various folksonomies, with the overall aim to better understand the semantics of tags and the tagging process. Therefore we analyze the semantic content of tags in the Flickr ...

The Web is experiencing an exponential growth in the use of weblogs or blogs, websites containing dated journal-style entries. Blog entries are generally organised using informally defined labels known as tags. Increasingly, tags are being proposed as a ‘grassroots’ alternative to Semantic Web standards. We demonstrate that tags by themselves are weak at partitioning blog data. We then show how...

In the problems of image retrieval and annotation, complete textual tag lists of images play critical roles. However, in real-world applications, the image tags are usually incomplete, thus it is important to learn the complete tags for images. In this paper, we study the problem of image tag complete and proposed a novel method for this problem based on a popular image representation method, c...

The sensing capabilities of an Internet-of-Things (IoT) network are usually fixed at deployment. Adding new sensing modalities is a cumbersome process because it requires altering the deployed hardware. We introduce passive sensor tags that allow to easily and seamlessly add new sensors to existing IoT deployments without requiring hardware modifications or additional energy sources. Passive se...

This paper puts TAGs into an algebraic perspective. The operation of tree adjunction is shown to be a special case of function substitution within a derived theory. The underlying process of theory derivation is illustrated with the concrete example of free continuous tree algebras.

─ In this paper we provide the basis of using radio frequency identification (RFID) tags for advertisement. Two RFID tags that apply to the 866 MHz and 915 MHz operating frequencies, respectively, were designed based on the logos of two universities participating in this project. Several fabrication methods were used to build the RFID tags on different substrates. The experimental results exhib...

Mixture Hierarchical Model Instead of assuming that vt is normally distributed, assume that vt comes from a mixture of normal distributions Intuition: Suppose for “genre tags” clusters around 0.25 and for “acoustic tags” clusters around 0.05 then if = 0.20, then vt might have two peaks at 0.05 and -0.15. 10,870 songs 2 tag vocabularies 71 genre and subgenre tags (e.g., “rock”, “delta blues”, “t...

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as refer...

a compact multi resonator circuit for Chipless rfid tag is presented in this paper. The basic resonator is a shorted λ/4 Stepped Impedance Resonator (SIR). The tag is designed and simulated using High Frequency Structure Simulator and a 6 bit prototype is fabricated on rtduroid(εr=2.2 and tanδ=.0008) Substrate in area of 4.5x2cm2. Data is coded as amplitude variations in the frequency domain. H...
