Experiments on Pseudo Relevance Feedback Using Graph Random Walks

, 2012
International audienceIn this article, we apply a graph-based approach for pseudo-relevance feedback. We model term co-occurrences in a fixed window or at the document level as a graph and apply a random walk algorithm to select expansion terms ...

Knowledge graph based entity selection framework for ad-hoc retrieval

Web Semantics
Recent entity-based retrieval models utilizing knowledge bases have shown significant improvement in ad-hoc retrieval. However, a lack of coherence between candidate entities can lead to query intent drift at retrieval time.

Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

Advanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

Anchored dense-chain pseudo-relevance feedback: sequential state refinement for neural retrieval

Journal of King Saud University: Computer and Information Sciences
Pseudo-relevance feedback (PRF) has been shown to improve the effectiveness of bag-of-words retrieval models. However, the incorporation of PRF into dense neural retrieval remains challenging. Direct updates to query embeddings can induce semantic drift,

中文專利前案檢索模式之成效評估 Evaluation of Prior Art Search Mothods [PDF]

Jiàoyù zīliào yǔ túshūguǎn xué, 2011
全球各地的專利申請件數近十多年來不斷的成長，各國專利主管單位皆積極的增聘專利審查官，以應付漸增的數量，並確保專利審查的品質。審查人員在決定核發專利前，都必頇執行前案檢索，以確定是否有先前之專利或技術，與該申請案雷同，做為判斷專利核駁的依據。對產業界而言，在專利申請前或專利訴訟中，也常執行前案檢索，以確保沒有誤觸他人之專利權。因此，專利前案檢索的結果，對當事人有極大的影響。國外在此方面的研究，已有數年的投入。但針對中文的專利，則付之闕如。本研究以臺灣的中文專利為對象，進行五種檢索模式的成效比較 ...

LLM-Assisted Pseudo-Relevance Feedback

Query expansion is a long-standing technique to mitigate vocabulary mismatch in ad hoc Information Retrieval. Pseudo-relevance feedback methods, such as RM3, estimate an expanded query model from the top-ranked documents, but remain vulnerable to topic drift when early results include noisy or tangential content.

Improvement of Trademark Retrieval Using Pseudo Relevance Feedback [PDF]

Proceedings of the 11th Indian Conference on Computer Vision, Graphics and Image Processing, 2018
As the number of registered trademarks become larger, the demand for trademark retrieval systems with high accuracy has grown to reduce the burden of human searchers. In particular, precision at high recall is important to avoid erroneous registration of newly submitted trademarks.

Intelligent Maintenance Review for Robots: Multimodal Information, Deep Diagnosis and Embodied Artificial Intelligence

Advanced Robotics Research, EarlyView.
This review maps the methods to monitor robots’ health by fusing vibration, sound, control signals, vision, force, and oil information with artificial intelligence. It identifies deep learning, transfer learning, digital twins, and physics‐informed models as key methodological pathways enabling earlier diagnosis, safer human–robot collaboration, and ...

Tumor‐Derived LAMB3 Drives Immunosuppressive LRRC15+ Fibroblast Formation During Pancreatic Ductal Adenocarcinoma Development

Advanced Science, EarlyView.
A single‐cell atlas of pancreatic ductal adenocarcinoma development reveals progressive ductal‐fibroblast‐immune crosstalk. Tumor‐derived LAMB3 drives the formation of immunosuppressive LRRC15+ fibroblasts through the ITGB1/FAK/MAPK/FOSL2 signaling. Glycolytic reprogramming upregulates LAMB3 and correlates with LRRC15+ fibroblast enrichment.

A Keratinocyte‐Mast Cell NF‐κB2/CXCL2/IL‐6 Amplification Loop Enhances Cutaneous Antifungal Defense Against C. albicans

Advanced Science, EarlyView.
ABSTRACT Mast cells (MCs), key innate immune sentinels at the host–environment interface, serve as primary responders to invading pathogens. However, their specific contribution to host defense against cutaneous Candida albicans (C. albicans) infection and their synergy with other immune and non‐immune cells remain poorly understood. Here, we show that
