UniPiSynthema POS tagger |
| Autore/i |
Carlo Aliprandi, Carmignani Nicola, Deha Nedjma, Mancarella Paolo Maria, Rubino Michele |
| Descrizione |
The UniPiSynthema POS tagger basic assumption is that contextual information
affects the environment where the word has to be tagged. In order to tag the word
with the most likely PoS it is necessary to have a high-order representation of the
context. This assumption has been consolidated into stochastic methods that are
based on a second order Markov Model.

This rule-based PoS tagger is developed by the NLP Group of the Dipartimento di Informatica of the
University of Torino, and it is part of the TULE framework. It takes as input the result of the
morphological analysis of a sentence, which may include multiple entries for each word when
an ambiguity is present. The output of the tagger is a sequence of single entries, each of which
is associated with an input word.

| Descrizione |
VeST is a symbolic rule tagger that uses little quantitative and statistical information.
Most of its computational work is based on tagged lexical information available in datasets
made available from previous work in the field. The system also uses a morphological
analyzer which is only activated for derivational nouns, cliticized verbs and some adjectives.
It is also activated as a guesser by unknown, and out of vocabulary words which will end up
with a default classification in case of failure: uppercase words are labeled proper nouns,
lowercase words common nouns.

classifier for learning how to chunk texts. Maximum Entropy is a more efficient technique than SVM, and
by complementing it with dynamic programming it can achieve similar levels of accuracy. |

IRSTLM
| Nome |
IRSTLM Toolkit |
| Autore/i |
Marcello Federico, Nicola Bertoldi |
| Descrizione |
The IRST Language Modeling Toolkit features algorithms and data structures suitable
to estimate, store, and access very large LMs. Our software has been integrated into a popular
open source Statistical Machine Translation decoder called Moses, and is compatible with
language models created with other tools, such as the SRILM Tooolkit.

LexSub
| Nome |
LexSub |
| Autore/i |
Diego De Cao, Roberto Basili |
| Descrizione |
The LexSub experimental platform proceeds through three steps: 1) the extraction of
the lexical substitution sets for the target words, 2) the acquisition of domain models for
candidates and 3) the ranking of candidate lexical substitutes over individual sentences
according to the acquired domain models. A further step 4) back-off is included to deal
with test cases for which the step 1) produces an empty candidate set.

Cedat85
automatic speech recognition system
| Nome |
Cedat85 automatic speech recognition system |
| Autore/i |
Maria Palmerini |
| Descrizione |
The system has been developed within a research project led in 2008 by Cedat 85 in
cooperation with the European Media Laboratory in Heidelberg. It's based on the most
recent IBM VoiceTailor technology; Cedat 85 provided the whole training process (acoustic
data, text data, scripts) for spontaneous Italian language. Some of the features of VoiceTailor
system are the speaker independence, the possibility to manage spontaneous speech, to use
unlimited vocabularies, to use different acoustic and language models, to manage noise and
the possibility to set some parameters in order to choose different strategies with respect to
accuracy or speed. The system works in a Linux environment and can run on more processors in
order to have more elaborations running in parallel.

Syllable-Based ASR System of Naples University
| Nome |
Syllable-Based ASR System of Naples University |
| Autore/i |
Francesco Cutugno, Bogdan Ludusan, Antonio Origlia, Serena Soldo |
| Descrizione |
The recognition system uses the syllable as base unit. In a first stage, the continuous
speech sequence is divided in syllable-like units using an energy-based algorithm. Then,
the obtained syllables are passed to a classifier in order to calculate the syllable/class probability
distribution. In the final stage, a Viterbi-like decoding algorithm based on multistage graphs will
find the most likely sequence corresponding to the audio input.

TSpeech |
| Autore/i |
Leandro D’Anna, Gianpaolo Coro, Francesco Cutugno |
| Descrizione |
TSpeech is an Abla srl proprietary speech recognizer, based on standard decoding algorithms,
with syllabic acoustic models. The recognition phase is followed by a rescoring session, based on
syllables energy and duration templates, which recover some recognition errors.

Coreference Resolution Module
| Nome |
TEXTPRO |
| Autore/i |
Octavian Popescu, Bernardo Magnini |
| Descrizione |
The coreference system has been developed to decide wether two mentions refer to the same
entity or not. The input of the systems consists of a list of Named Entities of type Person, i.e. Person
Names (PNs), that have been automatically recognized in a document collection. Its output consists
of a number of clusters of PNs, where each cluster is interpreted as the set of PNs that refer to the
same entity.
