چکیده

We have developed two conceptually different systems that are able to identify named entities from spoken audio. One (referred to as SPRACH-S) has a stochastic finite state machine structure for use with an acoustic model that identifies both words and named entities from speech data. The other (referred to as SPRACH-R) is a rulebased system which uses matching against stored name lists, partof-speech tagging, and light phrasal parsing with specialised named entity grammars. We provide an overview of the two approaches and present results on the Hub-4E IE-NE evaluation task.

Using a semantic network for information extraction

This paper describes the approach to knowledge representation taken in the LaSIE Information Extraction (IE) system. Unlike many IE systems that skim texts and use large collections of shallow, domain-specific patterns and heuristics to fill in templates, LaSIE attempts a fuller text analysis, first translating individual sentences to a quasi-logical form, and then constructing a weak discourse...

Lasie Jumps the Gate

The beneets of the eeective creation of Information Extraction (IE) in the last ten years, driven by the ARPA TIPSTER programme and the associated MUC evaluations, have been enormous, but it must now be time to ask what research issues face the systems we have built and what we should do next. We suggest that there are two classes of important research issues: those requiring detailed comparati...

1998 Hub-4 Information Extraction Evaluation

This paper documents the Information Extraction Named-Entity Evaluation (IE-NE), one of the new spokes added to the DARPA-sponsored 1998 Hub-4 Broadcast News Evaluation. This paper discusses the information extraction task as posed for the 1998 Broadcast News Evaluation. This paper reviews the evaluation metrics, the scoring process, and the test corpus that was used for the evaluation. Finally...

Coreference Resolution in a Multilingual Information Extraction System

We present in this paper the coreference mechanism implemented in the M-LaSIE system, a prototype multilingual Information Extraction (IE) system. We describe an experiment in which texts from a parallel French/English corpus were marked up manually and processed by the system following the MUC coreference annotation scheme. This experiment allows us to assess the applicability of the MUC annot...

ایجاد تجربی بیماری آنتریت در جوجه های گوشتی با استفاده از جدایه های PERFRINGENS CLOSTRIDIUM از موارد حاد بیماری در ایران

To establish an stable challenge system for induction of necrotic enteritis (NE) in broiler chickens, different potential factors and predisposing conditions were imposed in 6 separate different experiments using 525 day-old chicks in total. Despite the presence of some predisposing factors and using 4 isolates of Clostridium perfringens ( CP ) from acute and severe NE outbreaks as challenge ...
