TagMe! is a tagging and exploration front-end for Flickr images, which enables users to annotate specific areas of an image, i.e. users can attach tag assignments to a specific area within an image and further categorize the tag assignments. Additionally, TagMe! automatically maps tags and categories to DBpedia URIs to clearly define the meaning. In this work we discuss the differences between ...
With a large amount of geotagged resources from smart devices, it is important to provide users with intelligent location-based services. Particularly, in this work, we focus on spatial ranking service, which can retrieve a set of relevant resources with a certain tag. This paper designs ranking algorithm in order to find out a list of locations which are collected from geotagged resources on S...
The existence of emergent semantics within social metadata (such as tags in bookmarking systems) has been proven by a large number of successful approaches making the implicit semantic structures explicit. However, much less attention has been given to the factors which influence the “maturing” process of these structures over time. A natural hypothesis is that tags become semantically more and...
Entity ranking has recently emerged as a research field that aims at retrieving entities as answers to a query. Unlike entity extraction where the goal is to tag the names of the entities in documents, entity ranking is primarily focused on returning a ranked list of relevant entity names for the query. Many approaches to entity ranking have been proposed, and most of them were evaluated on the...
Further kinematical variables are suggested, in which to compare the putative leptonic W plus 4-jet top quark signal with the QCD background. We show that the lepton rapidity asymmetry, the p T-ranking of the tagged b-jet, the double-tag probability, the reconstructed t + ¯ t invariant mass, and the lepton energy in the parent top quark rest-frame, all display interesting differences between si...
Automatic image annotation is a process in which computer systems automatically assign the textual tags related with visual content to a query image. In most cases, inappropriate tags generated by the users as well as the images without any tags among the challenges available in this field have a negative effect on the query's result. In this paper, a new method is presented for automatic image...
The success of information retrieval style keyword search on the web leads to the emergence of XML based keyword search. The text database and XML database differences leads to three new challenges: 1) The users search intention is to be identified, i. e. , the XML node types that user wants to search for and search via is identified. 2) The similarities in tag name, tag value and the structure...
در بیان و خالص سازی پروتئین های نوترکیب از توالی مکملی معروف به دنباله استفاده میشود که از انواع آنها می توان به his-tag، gst-tag، mbp-tag وstrep-tag اشاره نمود. وجود این توالیها موجب تسهیل وتسریع امر خالص سازی میگردد و در این میان his-tag پرکاربردترین این توالی هاست. در بسیاری از مواقع حضور این دنباله ها میتواند تاثیر منفی بر روی ساختار و عملکرد پروتئین داشته باشد اما در مطالعات معمولا این مسئ...
Multimedia content is uploaded, tagged and recommended by users of collaborative systems such as YouTube and Flickr. These systems can be represented as tagged-graphs, where nodes correspond to users and taggedlinks to recommendations. In this paper we analyze the online computation of user-rankings associated to a set of tags, called a facet. A simple approach to faceted ranking is to apply an...
Folksonomies complete the methods of indexing scientific documents. Now scientists in their function as readers may play an active role in science communication as well, since they can tag documents with terms taken from their professional or personal environment. Folksonomies allow the indexing of documents by everyone without following any rules. Besides the benefits of folksonomies there are...
