Query-by-example search often uses dynamic time warping (DTW) for comparing queries and proposed matching segments. Recent work has shown that comparing speech segments by representing them as fixed-dimensional vectors — acoustic word embeddings — and measuring their vector distance (e.g., cosine distance) can discriminate between words more accurately than DTW-based approaches. We consider an ...

Relatively few query tools exist for data exploration and pattern identification in time series data sets. In previous work we introduced Timeboxes. Timeboxes are rectangular, direct-manipulation queries for studying time-series datasets. We demonstrated how Timeboxes can be used to support interactive exploration via dynamic queries, along with overviews of query results and drag-and-drop supp...

Shill bidding, where a seller masquerades as a buyer bidding for her own item to inflate the price, has challenged the classical auction theories. We show that with the possibility of shill bidding, a multi-round single-unit English auction has neither pure-nor mixed-strategy Perfect Bayesian Equilibria (PBE) when there is no gap between the seller's valuation and the lowest possible buyer valu...

There are lots of historical handwritten documents with information that can be used for several studies and projects. The Document Image Analysis and Recognition community is interested in preserving these documents and extracting all the valuable information from them. Handwritten word-spotting is the pattern classification task which consists in detecting handwriting word images. In this wor...

We will demonstrate our CVPR2000 paper ”Measurement of Color Invariants” for the cases of image retrieval based on query by example and for color image segmentation. Both are of importance in content based access of image and video data. We demonstrate the usefulness of the proposed color invariants in image retrieval by example systems. We show that an image retrieval query should include the ...

Detection of events and actions in video entails substantial processing of very large, even open-ended, video streams. Video data present a unique challenge for the information retrieval community because properly representing video events is challenging. We propose a novel approach to analyze temporal aspects of video data. We consider video data as a sequence of images that forms a 3-dimensio...

This paper describes how semantic annotations in terms of a domain ontology and theme hierarchy can be used for organising and reusing educational resources. A case study is presented in the domain of human genetics. The technology has been developed as a part of the Eurogene project and allows the user to submit, annotate and retrieve multimedia learning resources in nine European languages. W...

Li Yang and Jiankang Wu have designed a semantic image database system (OISDBS) for structural management of image data. They describe a semantic image data model and propose a diagrammatic query language with a Query-by-example (QBE) in order to manipulate the pictorial database directly. They also describe an implementation of OISDBS build on ISDBS, a relational image database system. In this...

We study a model of decentralised bilateral interactions in a small market where one of the sellers has private information about her value. There are two identical buyers and another seller, apart from the informed one, whose valuation is commonly known to be in between the two possible valuations of the informed seller. This represents an attempt to model alternatives to current partners on b...

Commercial systems such as Flickr display interesting photos from their collection as an interaction mechanism for sampling the collection. It purely relies on social activity analysis for determining the notion of interestingness. We propose an alternative technique based on content analysis for finding interesting photos in a collection. We use a combination of visual attention models and an ...
