FLOWING EVIDENCE BENCHMARK

How do we tell whether Evidence helps?

At the same writing position, with the same model and task, how does supplying retrieved paper passages change the first output? We compare matched versions and retain ties, unusable outputs and incomplete reviews.

Blind judge agent

First outputs are anonymized as X and Y

Continuation review: accuracy, fit to the writing task and usability
Returns: X preferred / tie / Y preferred / both unusable

Order check: X / Y → Y / X

HOW DOES BLIND JUDGING WORK?

① Anonymize both outputs
The judge sees the same draft and both first outputs without knowing which received Evidence.

② Compare and swap order
The judge applies task-specific criteria in X/Y and then Y/X order.

③ Review disagreements
A third pass resolves disagreements. Incomplete reviews remain in the denominator.

How are autocomplete positions stratified?

Before seeing generation outcomes, we check whether a retrieved passage contains a specific proposition that directly supports the next writing move. Those positions appear in the left opportunity group; the rest are ordinary positions on the right. We select a balanced sample from admitted papers in each field. The 50/50 split is experimental, not a measure of how often either type occurs in writing.

AUTOCOMPLETE · 110

Biology, statistics and astrophysics

55 positions on each side; statistics uses the ten-paper rerun.

AUTOCOMPLETE · 52

Psychology and climate science

26 positions on each side; psychology includes nine papers and climate science four.

How are the table percentages calculated?

Across five fields there are 81 source-opportunity positions. The original blind review preferred Evidence in 51; a task check moved one empty Evidence continuation to both unusable, leaving 50 in public counts. In the ordinary group, another pair of empty outputs moved from no winner to both unusable. Original verdicts remain visible on case pages.

Source contribution is a separate review: 16 of 21 Evidence wins entered into source review directly used retrieved papers; another 29 wins await review.

These are development-stage model judgments pending independent human review. They are not formal Benchmark conclusions and do not, on their own, establish causality.

A Survey on Improving Human Robot Collaboration through Vision-and-Language Navigation

1. INTRODUCTION

…orough resource that inspires further research at the intersection of VLN and robotics. We advocate that the future VLN systems should support proactive clarification, real-time feedback, and contextual reasoning through advanced natural language understanding (NLU) techniques. Additionally, decentralized decision-making frameworks with dynamic role assignment are essential for scalable, efficient multi-robot collaboration. These innovations can significantly enhance human-robot interaction (HRI) and enable real-world deployment in domains such as healthcare, logistics, and disaster response.

…D environments ( Anderson et al., 2018b ) ( Chen et al., 2019 ) , ( Thomason et al., 2020 ) , . In VLN tasks, agents interpret human instructions and leverage visual observations to traverse previously unseen spaces with increasing reliability. These agents integrate visual inputs and language instructions to generate navigation commands, provide verbal feedback, execute manipulation actions, and identify object locations ( Wu et al., 2023 ) . As a hallmark of embodied AI (EAI) ( Das et al., 2018 ) , VLN has catalyzed extensions into vision-language-guided manipulation and outdoor navigation.

Preferred by blind review

A key methodological shift in this trajectory was the move from graph-based navigation, in which agents traverse a pre-prepared navigation graph, to Vision-Language Navigation in Continuous Environments (VLN-CE), which removes the need for such graphs and allows agents to move freely in 3D spaces. This continuous formulation has been adopted because it better reflects realistic robotic navigation and permits agents to respond effectively to verbal commands.

Vision Language Navigation (VLN) plays a pivotal role in robotics, where an embodied agent carries out natural language instructions inside real 3D environments based on visual observations. Traditionally, the movements of agents in VLN environments are processed by a pre-prepared navigation graph that the agent traverses. Recognizing this, Krantz et al. [ 15 ] introduced an alternative approach known as Vision-Language Navigation in Continuous Environments (VLN-CE). Unlike traditional methods, VLN-CE eliminates the need for navigation graphs, enabling agents to move freely in 3D spaces. This framework has gained prominence for its realistic and adaptable approach to robotic navigation, allowing agents to respond effectively to verbal commands.

Not preferred in this comparison

The product produced no insertable continuation text.

The model explicitly returned a no-completion marker.

Judgment and task check

The blinded model review preferred the Evidence version. Its original rationale appears below.

Read the original model judgment

In this rationale, Output A = No Evidence; Output B = Evidence.

Output A is empty, providing no paragraph continuation despite the task requiring content. Output B provides a coherent academic paragraph that directly draws from the supplied source about VLN-CE, accurately describing the shift from graph-based navigation to continuous environments, the elimination of navigation graphs, and the benefits for realistic robotic navigation and verbal command response. The content is well-grounded in the source snippet, maintains the academic tone of the draft, and creates a logical bridge between the draft's discussion of VLN and the specific methodological evolution to continuous environments.

The passages are input material; their presence does not mean an output used them or that they support every claim. Draft and source passages are excerpted; no simulated scores or PDF appear here.
