Extracting information from plain text and restructuring them into relational databases raise a challenge as how to locate relevant information and update database records accordingly. In this paper, we propose a wrapper to efficiently extract information from unstructured documents, containing plain text expressed with natural-like language. Our extraction approach is based on the automata for...

This paper presents the BNSI Slovenian Broadcast News database project. The result of the project is a database with speech and text corpus oriented toward large vocabulary continuous speech recognition in general domain. The speech corpus consists of 36 hours of transcribed evening and late night news. The raw database material was captured in the archive of national broadcaster RTV Slovenia t...

A multi-database model of distributed information retrieval is presented, in which people are assumed to have access to many searchable text databases. In such an environment, full-text information retrieval consists of discovering database contents, ranking databases by their expected ability to satisfy the query, searching a small number of databases, and merging results returned by different...

Supervised machine learning algorithms for information extraction generally require large amounts of training data. In many cases where labeling training data is burdensome, there may, however, already exist an incomplete database relevant to the task at hand. Records from this database can be used to label text strings that express the same information. For tasks where text strings do not foll...

Particular uses of PNs with sense extension are focussed on and inspected taking into account the presence of PNs in lexical semantic databases and electronic corpora. Methodology to select ad include PNs in semantic databases is described; the use of PNs in corpora of Italian Language is examined and evaluated, analyzing the behaviour of a set of PNs in different periods of time. Computational...

The SuperKOM computer conferencing system was designed to incorporate many ideas from older messaging and conference systems in a simple and generalpurpose internal structure. This paper describes the design goals, and then describes how the internal structure of SuperKOM was designed to meet these goals. In particular, SuperKOM provides a distributed, highly structured conference system and in...

Bone et al. recently proposed an unsupervised signal-derived vocal arousal score (VC-AS) based on fusion of three intuitive acoustic features, i.e., pitch, intensity, and HF500, and have shown the effectiveness of quantifying human perceptual ratings of arousal robustly across multiple corpora. Due to the readily-applicable nature of the system, this objective quantification scheme could forese...

The present paper gives an account of the approach we have led so far to build a database of frozen units. Although it has long been absent from linguistic studies and grammatical tradition, linguistic frozenness is currently a major research issue for linguistic studies, as frozen markers ensure the economy of the language system. The objective of our study is twofold: we first aim to build a ...

The database group at University of Twente participates in TREC-8 using the Mirror DBMS, a prototype database system especially designed for multimedia and web retrieval. From a database perspective, the purpose has been to check whether we can get sufficient performance, and to prepare for the very large corpus track in which we plan to participate next year. From an IR perspective, the experi...
