Structured domains are characterized by the fact that there is an intrinsic dependency between certain key elements in the domain. Considering these dependencies leads to better performance of the planning systems, and it is an important factor for determining the relevance of the cases stored in a case-base. However, testing for cases that meet these dependencies, decreases the performance of ...

This paper describes a statistical methodology ibr automatically retrieving collocations from POS tagged Korean text using interrupted bigrams. The free order of Korean makes it hard to identify collocations. We devised four statistics, 'frequency', 'randomness', 'condensation', and 'correlation' .to account for the more flexible word order properties of Korean collocations. We extracted meanin...

This paper discusses musical form from a cognitive and a computational viewpoint. While several time-windows exist in the brain, we here put emphasis on the superchunks of up to more than 30 seconds lengths. We compare a strategy for auditive analysis based on human cognition with a strategy for automatic analysis based on feature extraction. The feature extraction is based on the musical featu...

A fundamental feature of research papers is how many times they are cited in other articles, i.e. how many later references to them there are. That is the only objective way of evaluation how important or novel a paper's ideas are. With an increasing number of articles available online, it has become possible to find these citations in a more or less automated way. This paper first describes ex...

In this paper we present an approach to allow indexing and retrieving vector graphics by content, using topological and geometric information automatically extracted from figures. The method described retrieves WMF ClipArt files as an instance of the general problem of searching vector drawings. Our prototype can already handle databases with thousands of drawings using commodity hardware. Our ...

Convenient access to handwritten historical document collections in libraries generally requires an index, which allows one to locate individual text units (pages, sentences, lines) that are relevant to a given query (usually provided as text). Currently, extensive manual labor is used to annotate and organize such collections, because handwriting recognition approaches provide only poor result...

In this paper we discuss some issues about information retrieval in multimedia presentations. We introduce a class of multimedia presentations made of independent and synchronized media, and discuss retrieval requirements of presentation fragments. Then we discuss a retrieval model able to reconstruct the fragments of a presentation from the atomic components returned by the execution of querie...

Given a software library whose components are represented by formal specii-cations, we distinguish between two types of retrieval procedures: exact retrieval, whereby, given a query K, we identify all (and only) the library components that are correct with respect to K; approximate retrieval, which is invoked in case exact retrieval fails, and which (ideally) identiies the library components th...

We develop methods for action retrieval from surveillance video using contextual feature representations. The novelty of our proposed approach is two-fold. First, we introduce a new feature representation called the action context (AC) descriptor. The AC descriptor encodes information about not only the action of an individual person in the video, but also the behaviour of other people nearby. ...
