TextWise LLC. participated in the TREC-7 Cross-Language Retrieval track using the CINDOR system, which utilizes a “conceptual interlingua” representation of documents and queries. The current CINDOR research system uses a conceptual interlingua constructed around the Princeton WordNet, which we are mapping into French and Spanish. The use of an interlingual representation of documents and queri...

A distributed information retrieval system with resource‐selection and result‐set merging capability was used to search subsets of the GOV2 document corpus for the 2008 TREC Million Query Track. The GOV2 collection was partitioned into host‐name subcollections and distributed to multiple remote machines. The Multisearch demonstration application restricted each search to a fraction of the avail...

Retrieval tasks provide learners with an opportunity to focus both on meaning and on form. There are four different retrieval directions. The present study aimed to identify the optimal direction of recall type retrievals during reading and to investigate the outcomes of each one. Forty-eight intermediate EFL learners took part in the study. One of the experimental groups was provided with the ...

of thesis entitled: Statistical Machine Learning for Bridging the Semantic Gap in Image Retrieval Submitted by HOI, Chu Hong (Steven) With the explosive growth of multimedia data, more and more research attentions have been devoted to visual information retrieval. Image retrieval, particularly content-based image retrieval (CBIR), has been actively studied in multimedia information retrieval co...

Information retrieval systems can be partitioned into two main classes: large-scale systems that make use of an inverted index or some other auxiliary data structure, intended for massive volumes of data; and the small-scale systems based upon sequential pattern matching that most computer users employ when hunting for missing email and news items. In this paper we describe a hybrid approach th...

The aim of the present study was to investigate whether and by which mechanism; histamine can induce state-dependent retrieval of passive avoidance task. The pre-training or pre-test intracerebroventricular (i.c.v.) injection of histamine (20µg/mouse) impaired retrieval, when it was tested 24 h later. In the animals, which retrieval was impaired due to histamine pre-training administration, pre...

Experiments carried out within evaluation initiatives for information retrieval have been building a substantial resource for further detailed research. In this study, we present a comprehensive analysis of the data of the Cross Language Evaluation Forum (CLEF) from the years 2000 to 2004. Features of the topics are related to the detailed results of more than 100 runs. The analysis considers t...

Increasing size and prevalence of real time information have become important characteristics of databases found on the internet. Due to changing information, the relevancy ranking of the search results also changes. Current methods in information retrieval, which are based on offline indexing, are not efficient in such dynamic search spaces and cannot quickly provide the most current results. ...
