Categorization of web pages – Performance enhancement to search engine

S. Lakshminarayana
2009 Knowledge-Based Systems  
Retrieval performance can often be improved using several algorithms and methods. Abundance in web has impelled to exert better search systems.  ...  The Spider/worm could be designed to traverse towards a better clustered 'B' group. A better verge for spider can be reached at shorter number of node (page) traversals.  ...  In the absence such works, the spider/worm either moves to the next page available at the least time or by network selection.  ...

Ajayi, Olusola Olajide
2014 IOSR Journal of Engineering  
recall, the fraction of the items of interest to the user that are retrieved by the system.  ...  On the other hand, the field of information retrieval has two classical performance evaluation metrics: precision, the fraction of the items retrieved by the system that are interesting to the user, and  ...  The stability of search engine performance was first examined by looking at the stability of the number of pages retrieved over the 5-week period.  ...

Learning to Retrieve Passages without Supervision [article]

Ori Ram, Gal Shachaf, Omer Levy, Jonathan Berant, Amir Globerson
2022 arXiv   pre-print
Moreover, a hybrid retriever over Spider and BM25 improves over both, and is often competitive with DPR models, which are trained on tens of thousands of examples.  ...  Last, notable gains are observed when using Spider as an initialization for supervised training.  ...  In addition, we add another filter: (5) spans should contain at least 2 tokens.  ...

2007 Proceedings of the sixteenth ACM conference on Conference on information and knowledge management - CIKM '07  
A document retrieval experiment is conducted using the TREC queries (1) without any phrases, (2) with the phrases recognized from a baseline noun phrase recognition algorithm, and (3) with the phrases  ...  It has been shown that using phrases properly in the document retrieval leads to higher retrieval effectiveness.  ...  Finally, we apply the recognized phrases from TREC queries to TREC document retrieval tasks, comparing the retrieval effectiveness of the IR system when (1) not utilizing phrases in the queries at all,  ...
