Document expansion for text-based image retrieval at WikipediaMM 2010 [PDF]

, 2010
We describe and analyze our participation in the Wikipedi- aMM task at ImageCLEF 2010. Our approach is based on text-based image retrieval using information retrieval techniques on the metadata documents of the images.

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

Molecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Using a Query Expansion Technique to Improve Document Retrieval [PDF]

, 2008
Query expansion (QE) is a potentially useful technique to help searchers formulate improved query statements, and ultimately retrieve better search results. The objective of our query expansion technique is to find a suitable additional term. Two query

Phenotypic and genotypic characterization of single circulating tumor cells in the follow‐up of high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Single circulating tumor cells (sCTCs) from high‐grade serous ovarian cancer patients were enriched, imaged, and genomically profiled using WGA and NGS at different time points during treatment. sCTCs revealed enrichment of alterations in Chromosomes 2, 7, and 12 as well as persistent or emerging oncogenic CNAs, supporting sCTC identity.

Automatic Query Expansion based Document Retrieval System using Hyper Tuned Graph Enhanced Bi-directional Encoder Representation from Transformers with Manifold Ranking Algorithm

International Transactions on Electrical Engineering and Computer Science
Document retrieval system automatic query expansion (AQE) adds relevant phrases to user searches to improve search results. AQE enhances recollection but introduces irrelevant phrases, increases computing complexity, and slows retrieval.

Query expansion with naive bayes for searching distributed collections [PDF]

, 2002
The proliferation of online information resources increases the importance of effective and efficient distributed searching. However, the problem of word mismatch seriously hurts the effectiveness of distributed information retrieval.

Tumor mutational burden as a determinant of metastatic dissemination patterns

Molecular Oncology, EarlyView.
This study performed a comprehensive analysis of genomic data to elucidate whether metastasis in certain organs share genetic characteristics regardless of cancer type. No robust mutational patterns were identified across different metastatic locations and cancer types.

Semantic Sequential Query Expansion for Biomedical Article Search

IEEE Access, 2018
The conventional sequential dependence model (SDM) has been proved to perform better than the bag of words model for biomedical article search because it pays attention to the sequence information within queries.
