Information Extraction (IE) systems typically rely on extraction patterns encoding domain-specific knowledge. When matched against natural language texts, these patterns recognize with high accuracy information relevant to the extraction task. Adapting an IE system to a new extraction scenario entails devising a new collection of extraction patterns a time-consuming and expensive process. To ov...

We will report on the IREX (Information Retrieval and Extraction Exercise) project. It is an evaluation-based project for Information Retrieval and Information Extraction in Japanese. The project started in May 1998 and concluded in September 1999 with the IREX workshop held in Tokyo with more than 150 attendance (IREX Commettee, 1999). There is a homepage of the project at (IREX, Homepage) and...

The large-scale applicability of knowledge-based information access systems such as the ones based on Information Extraction techniques strongly depends on the possibility of automatically acquiring the large amount of knowledge required. However, the basic assumption of the IE paradigm, i.e. that the information need is known in advance, limits inherently its applicability since the resulting ...

As a participating national lab in the inter-institutional effort to resolve performance issues of the non-elutable ion exchange technology for Cs extraction, we have carried out a series of characterization studies of UOP IONSIV IE-911 and its component parts. IE-911 is a bound form (zirconium hydroxide-binder) of crystalline silicotitanate (CST) ion exchanger. The crystalline silicotitanate r...

PURPOSE The ketogenic diet (KD) is an effective treatment for intractable epilepsy (IE), however the therapeutic mechanism is still unclear. This study was designed to investigate T helper type 17/regulatory T cell (Th17/Treg) levels in children with IE and age-matched healthy controls following KD. METHOD Circulating levels of Th17/Treg cells were analyzed by flow cytometry. Plasma concentra...

Relation Discovery discovers predicates (relation types) from a text corpus relying on the co-occurrence of two named entities in the same sentence. This is a very narrowing constraint: it represents only a small fraction of all relation mentions in practice. In this paper we propose a high recall approach for predicate extraction which enables covering up to 16 times more sentences in a large ...

ILQUA first participated in TREC QA main task in 2003. This year we have made modifications to the system by removing some components with poor performance and enhanced the system with new methods and new components. The newly built ILQUA is an IE-driven QA system. To answer “Factoid” and “List” questions, we apply our answer extraction methods on NE-tagged passages. The answer extraction metho...

This paper presents new Information Extraction scenarios which are linguistically and structurally more challenging than the traditional MUC scenarios. Traditional views on event structure and template design are not adequate for the more complex scenarios. The focus of this paper is to show the complexity of the scenarios, and propose a way to recover the structure of the event. First we ident...

A Job Shop Scheduling Problem (JSSP), where p processes and n jobs should be processed on m machines so that the total completion time is minimal, a well-known problem with many industrial applications. Many researchers focus JSSP classification algorithms address different classes. In this research work, production times, very theme covered in Industrial Engineering (IE), are integrated into a...

Chaotic maps used to shuffle and manipulate the image pixels are important for encryption (IE). In this study, a novel 2D optimized chaotic map (OPMAP) using triple-objective differential evolution (TODE) algorithm is presented IE. A model OPMAP with eight decision variables empirically designed, then its determined utilizing TODE through minimizing function that involving Lyapunov exponent (LE...
