Beyond term indexing: A P2P framework for Web information retrieval

Karl Aberer, Martin Rajman, Vinh Toan Luu, Ivana Podnar, Fabius Klemm

Web search over peer-to-peer (P2P) networks shows promise to become an alternative to the state-of-the-art search engines since P2P overlays offer means for decentralized search across widely-distributed document collections. However, the design of effecti ...

Machine Learning Approaches to Text Representation using Unlabeled Data

Mikaela Keller

With the rapid expansion in the use of computers for producing digitalized textual documents, the need of automatic systems for organizing and retrieving the information contained in large databases has become essential. In general, information retrieval s ...

Inferring Document Similarity from Hyperlinks

Samy Bengio, David Grangier

Assessing semantic similarity between text documents is a crucial aspect in Information Retrieval systems. In this work, we propose to use hyperlink information to derive a similarity measure that can then be applied to compare any text documents, with or ...

Inferring Document Similarity from Hyper-links

Samy Bengio, David Grangier

Assessing semantic similarity between text documents is a crucial aspect in Information Retrieval systems. In this paper, we propose a technique to derive a similarity measure from hyper-link information. As linked documents are generally semantically clos ...

Information Retrieval (IR) aims at solving a ranking problem: given a query

q

and a corpus

C

, the documents of

C

should be ranked such that the documents relevant to

q

appear above the others. This task is generally performed by ranking the documen ...

On the Use of Information Retrieval Measures for Speech Recognition Evaluation

Hervé Bourlard, Daniel Gatica-Perez, John David Scott Dines, Darren Moore

This paper discusses the evaluation of automatic speech recognition (ASR) systems developed for practical applications, suggesting a set of criteria for application-oriented performance measures. The commonly used word error rate (WER), which poses ASR eva ...

Information Retrieval on Noisy Text

Hervé Bourlard, David Grangier, Alessandro Vinciarelli

Spoken Document Retrieval (SDR) consists in retrieving segments of a speech database that are relevant to a query. The state-of-the-art approach to the SDR problem consists in transcribing the speech data into digital text before applying common Informatio ...

Joint Textual And Visual Cues For Retrieving Images Using Latent Semantic Indexing

Martin Vetterli, Serge Ayer, Zoran Pecenovic

In this article we present a novel approach of integrating textual and visual descriptors of images in a uniﬁed retrieval structure. The methodology, inspired from text retrieval and information ﬁltering is based on Latent Semantic Indexing (LS1). ...

Dynamic overview techniques for image retrieval

Pearl Pu Faltings

One difficulty often overlooked in information retrieval systems is that search criteria themselves are often poorly defined. People describe their information needs in many different ways and frequently change their goals depending on the current results ...
