text: The standard approach of job search engines disregards the structural aspect
of job announcements in the Web. Bag-of-words indexing leads to a high amount
of noise. In this paper we describe a method that uses local grammars to transform
unstructured Web pages into structured forms. Evaluation experiments show high
efficiency of information access to the generated documents.

text: 'The term uncertainty decoding has been phrased for a class of robustness
enhancing algorithms in automatic speech recognition that replace point estimates
and plug-in rules by posterior densities and optimal decision rules. While uncertainty
can be incorporated in the model domain, in the feature domain, or even in both,
we concentrate here on feature domain approaches as they tend to be computationally
less demanding. We derive optimal decision rules in the presence of uncertain
observations and discuss simplifications which result in computationally efficient
realizations. The usefulness of the presented statistical framework is then exemplified
for two types of realworld problems: The first is improving the robustness of
speech recognition towards incomplete or corrupted feature vectors due to a lossy
communication link between the speech capturing front end and the backend recognition
engine. And the second is the well-known and extensively studied issue of improving
the robustness of the recognizer towards environmental noise.'

text: In distributed and network speech recognition the actual recognition task
is not carried out on the user{\rq}s terminal but rather on a remote server in
the network. While there are good reasons for doing so, a disadvantage of this
client-server architecture is clearly that the communication medium may introduce
errors, which then impairs speech recognition accuracy. Even sophisticated channel
coding cannot completely prevent the occurrence of residual bit errors in the
case of temporarily adverse channel conditions, and in packet-oriented transmission
packets of data may arrive too late for the given real-time constraints and have
to be declared lost. The goal of error concealment is to reduce the detrimental
effect that such errors may induce on the recipient of the transmitted speech
signal by exploiting residual redundancy in the bit stream at the source coder
output. In classical speech transmission a human is the recipient, and erroneous
data are reconstructed so as to reduce the subjectively annoying effect of corrupted
bits or lost packets. Here, however, a statistical classifier is at the receiving
end, which can benefit from knowledge about the quality of the reconstruction.
In this book chapter we show how the classical Bayesian decision rule needs to
be modified to account for uncertain features, and illustrate how the required
feature posterior density can be estimated in the case of distributed speech recognition.
Some other techniques for error concealment can be related to this approach. Experimental
results are given for both a small and a medium vocabulary recognition task and
both for a channel exhibiting bit errors and a packet erasure channel.

text: In this paper, we derive an uncertainty decoding rule for automatic speech
recognition (ASR), which accounts for both corrupted observations and inter-frame
correlation. The conditional independence assumption, prevalent in hidden Markov
model-based ASR, is relaxed to obtain a clean speech posterior that is conditioned
on the complete observed feature vector sequence. This is a more informative posterior
than one conditioned only on the current observation. The novel decoding is used
to obtain a transmission-error robust remote ASR system, where the speech capturing
unit is connected to the decoder via an error-prone communication network. We
show how the clean speech posterior can be computed for communication links being
characterized by either bit errors or packet loss. Recognition results are presented
for both distributed and network speech recognition, where in the latter case
common voice-over-IP codecs are employed.

text: This paper addresses the robustness of automatic speech recognition to environmental
noise. In order to account for reliability of the clean feature estimate we employ
the feature posterior density conditioned on observed noisy features to perform
uncertainty decoding. We investigate two approaches to estimate the posterior
using a discrete feature space, first conditioning only on the current observation,
and second on the whole feature sequence of an utterance. Experiments with Aurora
2 showed that the latter provides slightly better performance, as it allows for
exploiting the temporal correlations between consecutive features.

text: This paper considers the convolutive blind source separation of speech sources
in the presence of spatially correlated noise. We introduce a method for estimating
the scaled mixing matrix from the sources to the microphones even if coherent
noise is present. This is achieved by combining time-frequency sparseness with
the generalized eigenvalue decomposition of the power spectral density matrix
(PSD) of the noisy speech and noise-only microphone signals. Separation is performed
by spatial filtering with coefficients constructed by Gram-Schmidt orthogonalization
which places spatial nulls at the interferer{^A}?`s direction. Experimental results
show that our approach is capable of separating 2 sources in a reverberant environment
(RT60=0ms..500ms) degraded by significant directional noise.

text: This Paper deals with a new Technique for multi-channel separation of speech
signals from convolutive mixtures under coherent noise. We demonstrate how the
scaled transfer functions from the sources to the microphones can be estimated
even in the presence of stationary coherent noise. The key to this are generalized
eigenvalue decompositions of the power spectral density (PSD) matrices of the
noisy speech and noise-only microphone signals with a controlled estimation of
these matrices exploiting time-frequency sparseness of the speech sources. Separation
is further improved by subsequent Gram-Schmidt orthogonalization which places
spatial nulls at the interferers{\rq} directions, while noise reduction is improved
by employing a novel blocking matrix and adaptive interference canceller in a
Generalized Sidelobe Canceller (GSC)-like structure. We report promising experimental
results for 2 speech sources with significant coherent noise in reverberant environments
(RT60=0oms..500ms).

text: The generalized sidelobe canceller by Griffith and Jim is a robust beamforming
method to enhance a desired (speech) signal in the presence of stationary noise.
Its performance depends to a high degree on the construction of the blocking matrix
which produces noise reference signals for the subsequent adaptive interference
canceller. Especially in reverberated environments the beamformer may suffer from
signal leakage and reduced noise suppression. In this paper a new blocking matrix
is proposed. It is based on a generalized eigenvalue problem whose solution provides
an indirect estimation of the transfer functions from the source to the sensors.
The quality of the new generalized eigenvector blocking matrix is studied in simulated
rooms with different reverberation times and is compared to alternatives proposed
in the literature.

text: In this paper a switching linear dynamical model (SLDM) approach for speech
feature enhancement is improved by employing more accurate models for the dynamics
of speech and noise. The model of the clean speech feature trajectory is improved
by augmenting the state vector to capture information derived from the delta features.
Further a hidden noise state variable is introduced to obtain a more elaborated
model for the noise dynamics. Approximate Bayesian inference in the SLDM is carried
out by a bank of extended Kalman filters, whose outputs are combined according
to the a posteriori probability of the individual state models. Experimental results
on the AURORA2 database show improved recognition accuracy.
