The TREC 2004 Terabyte Track evaluated information retrieval in largescale text collections, using a set of 25 million documents (426 GB). This paper gives an overview of our experiences with this collection and describes Amberfish, the text retrieval software used for the experiments.

This paper provides an overview of experiments carried out at the TREC 2004 Terabyte Track using the Indri search engine. Indri is an efficient, effective distributed search engine. Like INQUERY, it is based on the inference network framework and supports structured queries, but unlike INQUERY, it uses language modeling probabilities within the network which allows for added flexibility. We des...

This paper describes the participation of the XLDB Group in the Monolingual IR task for the Portuguese language. We present tumba!, a Portuguese search engine, and we describe its architecture and asumptions. We discuss the way we used tumba! in CLEF, detailing the submitted runs and our experiments with ranking algorithms. In the end, we evaluate our participation and comment on future work.

We participated in two multi-document summarization tasks (Task 2 and Task 5) at the DUC-2004 formal run and evaluated the performance of our summarization system. Our system based on sentence extraction also uses a module to estimate similarity between sentences. The similarity information was used for either selecting the representative sentence among similar sentences or gathering key senten...

Speckled shrimp (Metapenaeus monoceros), is a commercially important prawn in the embayments and estuaries of the Mediterranean Sea. It is originally a Lessepsian species which had migrated from the Red Sea into the Mediterranean Sea through the Suez Canal. This study was carried out in the North-eastern Mediterranean Sea between November 2009 and October 2010 with monthly sampling of speckled ...

A study to evaluate the reproductive performance of Abergelle goat was carried out at Sekota District of Amhara National Regional State. On-farm flocks from two peasant associations were monitored for two years to collect data. Data collected included identification number of doe and kid, birth / kidding date, kid birth weight, sex of kid, post partum doe weight, litter size, parity of doe. Dat...

A Pilot Question Answering Task has been activated in the Cross-Language Evaluation Forum 2004 with a twofold objective. In the first place, the evaluation of Question Answering systems when they have to answer conjunctive lists, disjunctive lists and questions with temporal restrictions. In the second place, the evaluation of systems’ capability to give an accurate self-scoring about the confi...

This is the first time that THUIR participates in TREC Genomics Track. We took part in both Ad hoc retrieval task and Categorization task. Based on our retrieval system TMiner, our research in the Ad hoc retrieval task focuses on: (1) Category of organism retrieval strategy; (2) Primary Feature Model; (3) Query Expansion (QE) technology; (4) Result fusion method. Five official runs have been su...

This year, the Computer Vision Group at University of Central Florida participated in two tasks in TRECVID 2004: High-Level Feature Extraction and Story Segmentation. For feature extraction task, we have developed the detection methods for “Madeleine Albright”, “Bill Clinton”, “Beach”, “Basketball Scored” and “People Walking/Running”. We used the adaboost technique, and has employed the speech ...
