R2D2 at NTCIR-4 Web Retrieval Task
نویسندگان
چکیده
We evaluated the Relevance-based Superimposition Model at NTCIR 4 Web task A (survey retrieval) and B (target retrieval). We developed a distributed indexing / searching engine for treating the large amount of documents in a practical processing time. Some improvements of the retrieval precisions were achieved algorithmically.

R2D2 at NTCIR 2 Ad-hoc Task: Relevance-based Superimposition Model for IR
This paper describes our evaluation experiments for NTCIR 2 ad-hoc task. We developed a retrieval system using the Relevance-based Superimposition (RS) model, in which document vectors are modified based on the relevance of the documents. The major focus of this year is on combination of the RS model and query expansion (QE). We submitted fully automatic ad-hoc results brought by different para...
متن کاملOverview of the Informational Retrieval Task at NTCIR-4 WEB
This paper gives an overview of the Informational Retrieval Task 2 that was conducted from 2003 to 2004 as a subtask of the WEB Task at the Fourth NTCIR Workshop (‘NTCIR-4 WEB’). In the Informational Retrieval Task, we attempted to assess the retrieval effectiveness of Web search engine systems from a viewpoint of topical relevance, and to build a re-usable test collection suitable for evaluati...
متن کاملNTCIR-4 WEB Experiments at Osaka Kyoiku University - Static/Dynamic Scoring Using Link Structure Analysis and Web Page Grouping
We did gram-based indexing and the retrieval with NTCIR-4 WEB task. The time required to make indices are 34.7 hours. The size of indices is 30.2Gbyte. The median of retrieval time par word is 26msec. The ranking algorithm of retrieval results is based on a traditional probabilistic model. We report on the result of gram-based indexing and the retrieval, and propose a scoring method based on li...
متن کاملOverview of WEB Task at the Fourth NTCIR Workshop
This paper gives an overview of the WEB Task at the Fourth NTCIR Workshop (‘NTCIR-4 WEB’) conducted from 2003 to 2004. Through the NTCIR-4 WEB, we investigated the evaluation methods used to measure some tasks of Web information access, such as information retrieval, information classification, and information extraction. We used a 100-gigabyte document dataset that was mainly gathered from the...
متن کاملOverlapping Clustering Method Using Local and Global Importance of Feature Terms at NTCIR-4 WEB Task
In NTCIR-4 WEB Task D (Topical Classification Task), we present an overlapping clustering method for a Japanese meta search engine as an alternative to listing of ranked retrieved results, which most search engines adopt to present the retrieval results. The proposed method clusters the retrieved results dynamically according to two steps: (1) cluster labels consisting of the most important fea...
