Comparative study of indoor positioning datasets focusing on localization accuracy success rate and floor classification.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Indoor positioning systems (IPS) are crucial for enabling location-aware services in GPS-denied environments such as buildings, hospitals, and industrial facilities. However, the lack of standardized, high-quality datasets remains a significant barrier to the development and fair evaluation of localization algorithms. This paper presents a comprehensive comparative analysis of four widely used indoor positioning datasets-BLE Indoor, SODIndoorLoc, TUJI1, and UJIIndoorLoc-evaluating their localization accuracy, success rate, and floor classification performance. Through exploratory data analysis and systematic experimentation using an XGBoost model with consistent hyperparameters, we identify how dataset-specific characteristics such as signal sparsity, access point (AP) density, device heterogeneity, and spatial layout affect localization outcomes. Results show that while high AP density can enhance accuracy, other factors like environmental complexity, weak RSSI signals, and multi-device variability significantly influence model performance. Based on our findings, we offer practical guidelines for dataset selection, feature engineering, and design improvements to support robust and generalizable IPS development. This study provides critical insights for both researchers and practitioners aiming to advance reliable indoor localization solutions.
