Description(s):
by Marc Poch Riera (over 12 years ago)

The UPF Institute for Applied Linguistics, IULA was created in 1994 and is a research and research-training centre that actually consists of about 70 researchers. IULA members are UPF professors of the Department of Translation and Language Sciences, the Department of Information Technologies and the Department of Communication, 14 PhD research scholarship holders and 16 assistant researchers contracted for specific externally funded projects, in addition to UPF funded support staff. DTCL and IULA jointly organize the Mención-de-Calidad awarded PhD program "Comunicació lingüística i mediació multilingüe", with a significantly international student population.

The group Tecnologies dels Recursos Lingüístics, TRL (Language Resource Techologies), a member of IULATERM unit led by prof. Núria Bel, works in the creation, development and application of technologies related to the acquisition, production, formalization, management, validation and evaluation of language resources as required for Language Technologies, Natural Language Processing and Computational Linguistics.

The service automatically calls the FreeLing WS and makes use of its Named Entity Recognition tool to detect proper nouns. The languages supported are English, Catalan, Spanish, Asturian, Welsh, Galician, Italian, Russian and Portuguese.

LMF file merger Web Service SOAPSoaplab Es
PASSED
Given two LMF files, this webservice merges them into a single LMF file. It works for LMF files encoding the information in the same way, i.e. same labels, values and structure. This will work, for example, for merging different lexica learnt under PANACEA platform. If the LMF files contain equivalent information encoded in different ways, a mapping into a common format should be previously performed. WARNING: this version of the webservice only works for LMF files without references. Thi...

Location nouns classifier Web Service SOAPSoaplab Es
PASSED
This WS identifies location nouns in a part of speech tagged text (with FreeLing Morphosyntactic tagger V 3.0 WS). The classification is performed with a pre-trained Decision Tree. The output is a LMF file with the classifier prediction for each noun. You can choose to have this prediction as: - "scored": each noun gets a score of being or not being a member of the class (bigger than 0 means class member, smaller, non member of the class) - "filtered": the nouns are filtered according to t...

XML/TXT to Weka converter Web Service SOAPSoaplab Es
Categories:
PASSED
Given a XML signatures file (signatures.xml) and the indicators file (indicators.txt) with the nouns that belong or not to the class, this WS creates a file in ARFF format to experiment with Weka. Warning: the default encoding for input and outputs files is ISO-8859-1. It may be changed using optional parameters, but the two input files must have the same encoding, which must be indicated in the headers of the XML file.

Naive Bayes classifier Web Service SOAPSoaplab Es
PASSED
This webservice performs traditional Naive Bayes classification of instances given in a weka file. It outputs the predicted classification for each instance and some statistics about the performance of the classification. The parameters needed as input can be learnt using estimate_bayesian_parameters webservice.

Bayesian parameter estimation Web Service SOAPSoaplab Es
PASSED
Given a training set encoded as vectors of cue (or feature) occurrences, this web service estimates the parameters P(cuei|class): the probability of seeing each cue as a member or non-member of the class. This estimation is performed using Bayesian inference, which combines prior knowledge with observed data. The parameters estimated with this web service can be used, for example, to classify new instances using a Naive Bayes classifier. The output format is the one needed as input for the...

P clue/ lexical class from Weka computer Web Service SOAPSoaplab Es
Categories:
PASSED
Given a training set encoded as vectors of cue (or feature) occurrences in weka format, this web service computes P(cuei|class): the probability of seeing each cue as a member or non-member of the class using MLE approach (counts frequencies of appearance of each cue in each class). Inputs: - weka_signatures: classified instances encoded as cue vectors. Each slot of the vector contains the number of times each feature has been observed for that instance. Also, we add special slots: total nu...

P clue/ lexical class computer Web Service SOAPSoaplab Es
Categories:
PASSED
This WS calculates the probability of seeing a linguistic cue given a lexical class (P(cue|class) value). This probability is computed given the occurrences of cues in a corpus (codified in the signatures file) and the information of belonging or not belonging of these words to different classes (codified in indicators file). The probability is computed for each studied cue in the signatures file and for each class in the indicators file.
